Self-reliance type regulator is a new regulator type, relative to manual control valve, its advantage is able to automatically adjust; Relative to the electric control valve, it is not to need to external power, the advantages of application of practice has proved that in a closed water circulation system (such as hot water heating system, air conditioning chilled water system), the proper use of the valve, the flow distribution can be easily implemented system; Can realize the dynamic equilibrium of system; Can greatly simplify the system debugging work; Can stable work state of pump, etc., self-reliance type regulator is a lot of advantages, so more and more get the favour of the masses of customers, but to make the product better play, then in the installation, we need to pay attention to the following points,
1, self-reliance type regulator is used in the gas or low viscosity liquid medium, usually type ZZY self-reliance type pressure regulator for vertical installed in a horizontal pipe, when position space does not allow to flip or inclined outfit,
2, to facilitate the maintenance and operation, type regulator should leave proper space around on our own efforts,
3, when the medium is clean gas or liquid, self-reliance type control valve before the filter can not install,
4, the pressure regulating valve size is too big (DN 100 or higher), shall have the fixed bracket when confirmed that medium is very clean, 3 is not installed,
5, when the position is not allowed, by-pass valve (manual) can be omitted (we do not recommend),
After 6, self-reliance type regulator is set according to users need optional check valve, relief valve, etc.,
7, self-reliance type regulator used in steam or high viscosity liquid medium, usually type ZZY self-reliance type pressure regulator for inverted installed in a horizontal pipe, condenser (steam with self-reliance type) should be higher than that of pressure regulating valve actuator and below the valve before and after taking over, condenser shall be filled with cold water before use, irrigation after about 3 months time,
