With the heating system reform, household heat metering and sub-room temperature control has entered the implementation stage, the temperature control valve is installed in the radiator is already very popular, and with the temperature control valve to achieve sub-room temperature control, both the maximum energy conservation, but also satisfy different user needs for indoor temperature regulation is a good thing benefits the country, but how to select temperature control valve did not fully allow users to grasp, if not the right choice of products, not only to can not meet demand, and may give users an unnecessary economic losses, for which the author according to their own application experience, in which published some of my views, designed to give colleagues and users some useful help.
Temperature control valve is installed on the water pipes in the radiator temperature regulation (actually flow regulation) of a device. Manual and automatic temperature control valve is divided into two kinds of temperature control valve, automatic temperature control valve is also called Self-operated temperature control valve or automatic thermostat valve, are also referred to as the thermostat valve. Automatic temperature control valve is a temperature sensor Self-executing agencies and special supporting temperature control valve body composition
Thermostatic valve valve's structure often straight, angle valve two of the most common two-way valve. Two-way valve is mainly used for two-pipe system or a specially designed a new single-pipe system. In recent years, according to single and double pipe system differences, but also post-graduate output of a single-pipe system specifically applicable to the three links-style temperature control valve and the use of covert installation of suitable single-, double-tube system, a special four-way valve. The four-way valve is currently more common in imported products, such as Italy Jiekemini (GIACOMI-NI) of the four-way valve, which applies not only to all kinds of radiators, and it applies to single and double control systems, but also the ability to to meet the dark filled with a variety of pipe connections.
Thermostatic valve usually have manual, automatic two kinds, the principle of the valve movements are very different. Manual temperature control valve usually spiral lift spool, rotating handle designed a straight line through the spiral into a spool displacement. And automatic temperature control valve in order to meet the temperature sensor specific self-implementing agency of the straight-line moves, spool movement is usually designed to automatically reset the direct linear displacement, therefore the body under normal circumstances are not interchangeable. But there are also interchangeable, a specially designed valve can be generic, that is, automatic temperature control valve of the valve, attach a suitable manual screw lifting mechanism, can be realized manually, automatic common exchange between the two. This is particularly suitable to improve the situation in China have great practical value, in the present, many projects, developers in order to save the initial investment, first install a valve with automatic temperature control feature along with the spiral movements with special handles, so that both the achieved with 1 / 3 the cost of automatic temperature control valve (the price of basic equivalent to manual temperature control valve) for a manual temperature control valve, and gave the user automatic temperature control in the future to upgrade the space left behind. Even in the imports of this product is also rare in this area of Italy Jiekemini walk in front of the market provides such a range of manual, automatic temperature control valve between a known pairs adjustable temperature control valve, eight stalls setting, the indoor temperature as you set up, extremely convenient. Worthy of the world's larger HVAC valve suppliers. It is this range of manual and automatic temperature control valve of the valve between the particularity of, so choice will be complex, this complexity is not fine for some business people and caused speculation salesman "fish in" The opportunities. In this I remind that, in the current market there are a lot of automatic temperature control valve suppliers salesman will carry a simple adjustment handle automatic temperature control valve body of the net charge as a dual regulatory function of the temperature control valve to the user recommended, and some users to use such a temperature control valve, which is not very appropriate, there are great risks, so that although the automatic temperature control valve body with a simple adjustment on the handle, but the handle design idea of the automatic temperature control valve in order to meet the valve before the first installation of temporary works for the system adjusted to meet the test of water pressure test only, test the water pressure in the test process is completed, be replaced by automatic temperature control valve valve head, because it temporary, so the easy adjustment of the valve handle on the original loan for a fixed temperature control valve head for helical screw lifting the ordinary use. We all know that simple adjustment handle because of its temporary, one-time, generally use plastic, if used as the final frequency adjustment, the thread wear is very fast, not to mention working in the heating system, the spool up and down movements where there is a certain pressure circumstances, even in the absence of pressure systems, the spool itself alone will greatly speed up the spring pressure on the thread handle wear and tear, so use this product as can be upgraded to automatic temperature control valve of the Manual temperature control valve is not appropriate.
