Indoor Riser same floor drain is a novel design and construction and installation process is completed in the reinforced concrete floor will be followed by thin horizontal flat body floor drain and the pipe network, direct access to the leveling layer riser. Toilet drain after use, or to split water tanks hidden inside the separator in the pipe gallery. To facilitate the pipe network maintenance, set up inside the shower rooms are waterproof repair the door. The master bathroom, to bath water seal drainage network have sufficient reasonable arrangement should be elevated to the bottom of the bathtub over leveling layer. Leveling layer than the traditional floor height increase is only 55mm. Not only to solve the traditional clothing floor, sewer drip, Kiyomichi environmental health issues affect the neighbors stole a save investment with caisson pipe. Replacement of equipment and pipe network maintenance compared with the caisson pipe mode, the former light, the latter time-consuming and laborious.
The development of the same floor drain is not as difficult technique, but the traditional values. 2003 "Building Water Supply and Drainage Design Standards" provides that: to drain the water seal depth is based on the provisions of foreign norms established. 50mm water seal depth is to determine the gravity flow drainage system in the ventilator pipe and drain pipe diameter base. Trying to suck in some areas an additional valve, reducing water seal depth of practice is inappropriate. First, only a balance of negative pressure suction valve, but can not eliminate the pressure fluctuations. The second suction valve valve valve aging, loss of function caused after the indoor environmental pollution. Third, reduce the water seal to drain the water depth is bound to reduce the volume of water seal, easy to evaporate dry.
Can eliminate the negative pressure suction valve to siphon pumping loss is nearly zero. No pressure valves abolished by addition, but by "double" structure principle, the use of pipe network to be able to promote growth in water seal. Suction valve valve problem of aging is a technological breakthrough in the most crucial part, using wear-resistant, anti-oil, dense silicone rubber plus anti-aging agents, improve technical performance, the aging period of up to 8 ~ 10 years, is bound to home, changing a light bulb replacement is also easy.
Therefore, the Bell-floor drain in terms of a static or dynamic aspects of comparison, the superiority does not exist. Because the latter design is a low-water-sealed as the guiding ideology, specifically with less evaporation loss and high Huibu way to achieve high performance, high-quality suction valve located in the shelter to better ensure that its unique effects. To drain water seal to protect the concept should be updated. ball valve Trunnion Mounted Ball Valve Floating Ball Valve Top Entry Ball Valve ball valve V Type Ball Valve

Valve types and uses
Valve is closed parts (ram) along the channel center line perpendicular to the direction of movement of the valve. Valve in the pipeline used mainly for cutting.
Valve is to use a valve very broad, general diameter DN ≥ 50mm cut-off devices are selected it, and sometimes cut off a small-caliber devices also use valve, the valve has the following advantages:
① fluid resistance.
A smaller external force required to open and close ②.
③ medium flow unrestricted.
④ full-time, the sealing surface of the erosion by the working fluid valve smaller than the cut-off.
⑤ relatively simple shape, casting process is better.
Valve also has shortcomings:
① Overall size and height of a larger opening. Large space required for installation.
② opening and closing process, the sealing surface friction between the relatively easy to cause abrasions.
③ valve normally have two sealing surface, to the processing, polishing and maintenance of the increased number of difficulties.
First, the type of valve
1. Construction of divisible by ram
1) Parallel Gate Valve: sealing surface and vertical axis parallel to the two valve sealing surface parallel to each other.
In a parallel-type valve in order to wedge-thrust structure with the most common is common, both in the middle of two double-sided thrust wedge gate, which applies to low-voltage small-caliber valve (DN40-300mm) valve. Also have two rooms with a spring damper, spring can produce to the tight power is conducive to ram seal.
2) Wedge Gate Valve: sealing surface and the vertical axis into a certain point of view, that is, two sealing surface into a wedge-shaped valve.
Sealing surface of the tilt angle are generally 2 ° 52 ', 3 ° 30', 5 °, 8 °, 10 °, etc. The size of the angle depends primarily on medium high and low temperature. Generally higher operating temperature, the angle taken to be larger in order to reduce the temperature change occurs when the wedge housing possibilities.
In the wedge-type gate valve, a further single gate, Shuangzha divided board and elastic damper. Single wedge gate valve, simple structure, the use of *, but the sealing surface angle of the higher accuracy requirements, processing and maintenance more difficult, the temperature change is very likely to live wedge. Shuangzha plate wedge gate valve in the water and steam pipes in the media to use more. Its advantages are: the angle of the sealing surface precision low temperature is not easy to live a phenomenon caused by wedge, sealing surface wear, you can add pads compensation. However, this structural components are more easily bonded in the viscous medium, affecting sealing. More important is the upper and lower baffle long-term use is easy to produce rust, gate easily. Flexible wedge gate valve, it has a single wedge gate valve structure is simple, using * the merits, but also produce small amounts of elastic deformation of the cover sealing surface angle deviations arising during processing and improve the technics now been widely adopted.

Talk about pressure relief valves, emergency shut-off valve and open the valve settings
At present, the butterfly valve is used to achieve piping system as an on-off and flow control components, has been in the petroleum, chemical industry, metallurgy, water, electricity and many other areas to be very widely used. In the known butterfly has been recognized technology, its sealed form of multi-sealed structure, sealing material for rubber, PTFE and so on. As the structural characteristics of the restriction is not suitable for high temperature, high pressure and corrosion resistance, abrasion resistance and other industries.
Present a more sophisticated three eccentric butterfly valve is metal seal butterfly valve, valve and valve seat as the Siamese components, valve seat sealing surface layer welding temperature, corrosion resistant alloy material. Soft-stacked multi-ring fixed to the valve plate, this butterfly valve in comparison with the traditional high temperature, easy operation, open and close without friction, closed with the transmission of the torque increases to compensate for seal, to improve a butterfly valve sealing performance and durability advantages.
However, this butterfly is still in the course of the following problems:
1, due to soft and hard stacked multi-ring fixed to the valve plate, when the valve plate to its normal open state media, the formation of a positive sealing surface erosion, and metal sheets laminated in the soft-sealing tape subject to erosion, the direct impact on seal performance.
Third, because the principle of the three eccentric structure, the valve plate sealing surface and the seal between the valve seat is to rely on the torque transmission device so that pressure valve plate to the valve seat. Positive flow state, the media, the higher the pressure squeezed more tightly sealed. When the flow channel upstream medium with medium pressure increases when the valve plate and seat the pressure between the units is less than the medium pressure, the seal started to leak out.
High-performance 3-way eccentric hard-seal butterfly valve, its characteristics are: described by a soft T-shaped valve seat ring seal ring on both sides of the composition of multi-layer stainless steel sheet. Valve plate and valve seat sealing surface for the oblique cone structure, in the valve plate oblique cone surfacing temperature, corrosion resistant alloy materials; fixed platen in the regulation of rings between the spring and the adjustment bolt assembly with the platen structure. This structure effectively compensate for the tolerance between the sleeve and the valve stem in the medium zone and the elastic deformation under pressure to solve the two-way valve in the transmission medium of exchange that exist in the process of sealing problems. Use of soft T-seals on both sides of the composition of multi-layer stainless steel sheet with a metal seal and soft seal the dual advantages of both the low and high temperature cases, both with zero leakage sealing performance.
Test proved positive flow state (medium flow direction and the butterfly plate rotation in the same direction), the sealing surface pressure is the transmission of torque and media pressure on the valve plate of the role of the elected. Positive medium pressure increases, valve plate oblique cone surface and the valve seat sealing surface squeezed more tightly, sealing the better. When the counter-current state, the valve plate and valve seat through the seal between the drive torque to the valve seat so that pressure valve plate. With the reverse-media pressure, valve plate and valve seat unit between the positive pressure is less than medium pressure, the adjustment of the spring ring is contained in the subject after the deformation energy stored in compensation valve plate and valve seat sealing surface of the tight the pressure to play the role of automatic compensation. Therefore, this utility model, unlike existing technologies, as the valve plate to install software and hardware multi-ring, but directly installed on the valve body, in the platen, and the middle seat an additional adjustment ring is a very good two-way hard-sealing method . It can replace valve, the cut-off valve and ball valve. ball valve Trunnion Mounted Ball Valve Floating Ball Valve Top Entry Ball Valve ball valve V Type Ball Valve

Pneumatic butterfly valve in the powder system operating instructions
Pneumatic butterfly valve on the gas, liquid medium occasions we have discussed the use of more, and because the pneumatic valves used for solid materials (such as dust, powder) not, in the selection and use also there are many places worth exploring. Experience combined with the practical application of the following to talk about the see-zero.
Butterfly valve for the control of solid materials, often at the end of the tank as the discharge valve to use, such as cement cans, powder cans, etc. at the end of the tank to leak the news and quickly cut off. Because most of the dust materials containing large or small particles, the valve sealing surface on the wear and tear is not in doubt Selection properly, will greatly reduce the life of the valve, or valve leakage caused by very quickly, the impact of continued use. Such a case: there is a burden weighing system, the whole process of ingredients to achieve fully automatic with PLC control, and the ingredients of the discharge valve car uses three eccentric butterfly valve pneumatic, medium is a very fine powder particles. After a period of time with customers to reflect inside the drain valve, which often piles of powder to leak in the table. Detection valve is not leaking, but also reflects the previous customers of this valve is used, and the same medium, there is no such thing happened. In order to understand the whole story, the company sent to the scene, we have finally found the reason: the original, this medium is very small and a bit sticky, though the ingredients with a small vibration motor vehicles, the end of a number of materials attached to the tank wall and valve parts in the valve closed, stuck in the sealing surface around the valve can not be completely closed, with the result after re-installation of materials spill, with the passage of time, but also sealing surface wear very much, and even to show a trench.

Filters and pressure regulating valve to maintain
In the routine maintenance of vehicles, the air filter and PCV valve pressure easily be ignored. Moreover, often when they plug into the engine and endanger the normal working hours will be subject to remedy the situation as the replacement of the maintenance. In order to avoid premature engine wear (non-normal) and maintain the best working condition, the pressure of the air filter and PCV valve for regular inspection and replacement is all the more essential.
We emphasize on preventive maintenance of air filter is not an exaggeration. In the inhalation of air and fuel mixture before the air filter the air in the dust least squares, carbon and other debris, thus ensuring the cleanliness of the air inhaled. In fact, the volume per unit of fuel combustion, about the need for 10,000 per unit volume of air through the filter. And then a small dirt particles will also lead to internal engine parts and components related to the severe wear and tear.
Usually, manufacturers recommend regular maintenance of air filter replacement cycle for 48,000 km, and every 24,000 km to conduct a routine examination; the recommendation to maintain its conservative replacement cycle for 24,000 km.
The density of the atmosphere contains three basic particles of different pollutants, namely, dust, and carbon residue. In the open highway, the dust content of the more rural areas and low built-up areas. Dust concentration in the larger region, air filter inspection and replacement of higher frequency. Highways and traffic congestion in the region, because the concentration of emissions from vehicles, so the air in the carbon content was high.
Replacement of the oil during the day-to-day when, incidentally, check the air filter can be regarded as a good habit of the best of both worlds. At this point, won the filter, carefully read the depths of its folds inside. In some cases, appears to clean the external filter, but it is very dirty inside, and must immediately be replaced at this time.
Channeling PCV system will leak into the crankcase of the introduction of mixed-gas intake system, and then in the combustion chamber for secondary combustion.天少夜暂, oil, gasoline and other concentrates in the PCV valve into the internal deposition of colloidal sludge, resulting in PCV valve plug, resulting in improved internal crankcase gas pressure. Pressure led to the upgrading of the oil from the seal or gasket leakage Department, resulting in additional leakage of oil consumption and engine failure and so on. In addition, to increase the pressure on the crankcase vapors through the PCV make sticky oil and HC compounds have the air filter particles will inevitably reduce the accuracy of its filter. When the adhesion of foreign matter can not be completely closed PCV not appropriate amount of air will be the introduction of the combustion chamber, thus diluting the air / fuel mixture, which eventually led to the deterioration of motor vehicles and easy off idle performance.
The majority of manufacturers to provide normal maintenance of the PCV valve replacement cycle for the recommended 96,000 km; conservative replacement cycle for the maintenance of 48,000 km. In any case, check the air filter at the same time, be sure to test whether PCV valve plug and bonded. Ford PCV valve replacement cycle based on the recommendation of the different specific models for the 9.6 ~ 160,000 km range; GM also provided according to different models corresponding recommended PCV valve replacement cycle, the more broad range. When you on the ongoing maintenance of the vehicle replacement cycle of PCV valve doubts, please timely access to information on the owner's manual or maintenance. valve ball valve gate valve check valve globe valve butterfly valve

Explore ways to connect the valve characteristics and the application of performance
(1) thread connection valve. This connection is usually the end of the valve and out of cones processed into pipes or straight pipe thread, so that it can be connected to the cone tube or pipe nipple on the road. As a result of this connection may leak a larger channel, it can be used sealants, sealing or packing tape to plug the channel. If the valve body material can be welded, but very different thermal expansion coefficient, or changes in operating temperature range of a larger thread junction closure weld must be honey.
Valve thread Nominal mainly by valves in the 50mm below. Path size, if too large, the junction is very difficult to install and seal. In order to facilitate the installation and removal of the valve connecting thread in the pipeline system can be used at appropriate locations on the pipe connection. DN 50mm below the valve can be used as a socket pipe fittings, pipe thread socket will connect the two parts together.
(2) flanged connection valves. Valve flange connection, the installation and removal are more convenient. But the thread of the valve than the heavy, the corresponding prices are highest. Therefore, it applies to all kinds of pressure path and the pipe connection. However, when the temperature over 350 degrees, as bolts, gaskets and flange of a change to relax, but also significantly reduces the load bolts, a lot of stress on the flange connection may have a leak.
(3) welding to connect the valve. This connection applies to all kinds of pressure and temperature, in a moment under the condition of the Netherlands use more reliable than the flange connection. However, welding to connect the valve and re-installation of the demolition are more difficult, so its use is usually limited to long-term reliable operation, or use of the conditions of Dutch engraved, high temperature occasion. Such as thermal power stations, nuclear power engineering, the ethylene project pipeline. DN 50mm below the welding socket weld valves generally have a flat side to take charge of the pipeline. As the jack socket and pipe welding in the formation of the gap between, there may be some crevice corrosion medium, the vibration at the same time pipeline will connect the site of fatigue, so the use of socket welding subject to certain restrictions. Larger in nominal diameter, engraved with the use of the conditions of the Netherlands, the higher the temperature of the occasion, often the use of body welding groove on at the same time, to have the original lattice seam welding requirements, choice of technology must be perfect to complete the work of welders. ball valve Trunnion Mounted Ball Valve Floating Ball Valve Top Entry Ball Valve Three way ball valve V Type Ball Valve

As the jack socket and pipe welding in the formation of the gap between, there may be some crevice corrosion medium, the vibration at the same time pipeline will connect the site of fatigue, so the use of socket welding subject to certain restrictions. Larger in nominal diameter, engraved with the use of the conditions of the Netherlands, the higher the temperature of the occasion, often the use of body welding groove on at the same time, to have the original lattice seam welding requirements, choice of technology must be perfect to complete the work of welders. ball valve Trunnion Mounted Ball Valve Floating Ball Valve Top Entry Ball Valve Three way ball valve V Type Ball Valve
