Floor drain and the suction valve of the safety issues

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
