Heating measurement reform regulation is the premise, measurement is the means, energy saving is the goal, the indoor radiator control valve is the only device for user self-regulation, you must transform the installation, otherwise fail to save energy. Therefore, no matter what option is selected, there is no good temperature control products, energy saving is equal to empty talk. Heating measurement is the core of indoor temperature control device (also known as radiator thermostatic valve or radiator thermostatic valve, referred to as the thermostat valve or thermostatic valve), thermostatic valve can be achieved heating system temperature and thermal flow changes in regulation, there is no constant temperature Valve regulation, it is impossible to achieve better energy-saving effect. Choose a good thermostatic valve products, in order to have the practical effect of saving money. Saving money here means not saving on the purchase cost of a single product, but saving on heating costs. At present, with the continuous deepening of the heating metering process, new buildings must be forced to install radiator thermostatic control valve is well known. So, a good thermostatic valve (temperature control valve) What is the product? In accordance with relevant state regulations and industry standards require thermostatic valve must have the following functions: First, with a water pressure block or replace the cartridge Features. During heating and heating, the thermostatic valve can not work effectively due to various factors, and the maintenance staff can clean the thermostatic valve or replace the valve core under the condition of not stopping the heating, so as to ensure that the entire heating The normal operation of the system. Second, the thermostatic valve installed in the vertical two-pipe system must have a preset resistance function in order to more effectively and reasonably regulate the flow of the heating and the pressure of the heating pipe and adjust the balance of the area. These two requirements are the mandatory technical requirements of the Technical Regulation on Heating Metering (JGJ173-2009) promulgated by the Ministry of Housing and Urban-Rural Development. Third, the KV value of the thermostat valve can be pre-set function. Fourth, the thermostatic valve is also an important indicator is the heating valve leakage problem, the valve there is the possibility of water leakage, especially in the user's home heating valve. Therefore, the valve is anti-leakage function, is to determine the merits of thermostatic valve is a very important reference indicator. Thermostatic valve is an automatically controlled valve, in the case of unmanned use, the thermostatic valve will automatically repeat the work every day, when the thermostatic valve leaks, no one can not judge, therefore, the thermostatic valve may seem small, but it is An important livelihood issue. Proposed new residential buildings should be selected with the following basic functions of the thermostatic valve: (1) free tool can take with water pressure block or replace the spool, with special tools with water pressure block or replace the spool. The difference between the two is relatively large, free use of special tools is very convenient, small tools available everywhere. Their own operation can be repaired and replaced, and special tools is a special tool, high prices, not retail. (2) The vertical two-pipe system must have a function of a preset drag coefficient in order to solve the problem of hydraulic imbalance. (3) anti-leakage features, allowing users to rest assured. Recently, all over the country for the old residential building heating metering reform is also gradually started, many transformation programs came into being, the basic is to give priority to household control. The so-called household control, that is, as a unit of measurement and temperature control. Regardless of the choice of program, must include temperature control products, the current commonly used products are: electric valve, electric two-way valve, electric ball valve and other related products, these products are used 220 volt power for the water system. Electric valve is the core components of paraffin warm package, which is composed of paraffin and metal powder, under the conditions of heat conduction, warm packets of paraffin and metal powder easily layered, resulting in metal powder precipitation, accelerated the failure of the electric valve At the same time, the electric valve can not be replaced online spool spool. Existing (old) residential building renovation recommended User selected temperature control valve should have the basic functions: (1) working voltage below 24 volts of safety products, there will be no leakage, electric shock and other conditions. (2) Working power is less than 1 watt, saving energy while saving energy. (3) The valve should be normally open after abnormal power failure, to avoid affecting the heating system and causing unnecessary disputes. (4) With water pressure block or replace the spool, easy to maintain and maintain. (5) Anti-leakage function, allowing users more at ease. (6) Automatic return to the product after the fault (that is, to maintain the normally open state), but also to protect the normal operation of the heating system is necessary. The selection of good temperature control products is crucial, which is related to the vital interests of ordinary people. In particular, development enterprises, construction enterprises, heating enterprises and heating supply enterprises must use temperature control products that conform to the national technical standards and really do practical work for ordinary people, laying a solid foundation for the sound development of heating metering in our country.
