Automatic exhaust valve, a valve is used, basically each valve manufacturers will have. The principle of its working principle and the other valve almost, but is not the same characteristics. We OLS valve company some research on this aspect, the following will come to share the characteristics, applications and the principle of the automatic exhaust valve.
HVAC systems and HVAC system in the process of operation, many adverse effects on release of water in the heating gas such as hydrogen, oxygen and other brings damage to the system and reduce the thermal effect, these gases, such as not timely drain will have many adverse consequences. Such as: corrosion by oxidation leads to the formation of the radiator; bag; hot water circulation is not smooth uneven, some local radiator is not hot; with a gas pipeline running noise; cavitation phenomenon of the cycle pump. So the exhaust system must be discharged in time, the important role that use automatic exhaust valve.
A, features:
1). Only the exhaust, undrained. Steam, water from the disk design adopts special structure, ensure the exhaust will not drain.
2) reliable performance. Emission device materials using PK-EP. And compared to all known synthetic materials, PK-EP has the best performance with the highest reliability. The PK-EP can withstand high temperature than the exhaust valve of the operating temperature is much higher. O type sealing ring using the optimization of material EPDM, to ensure that the high temperature O type sealing ring is still has good flexibility and reliability. Exhaust valve spool of the internal spring using special materials, and the use of imported nickel stainless steel, prevent oxidation if oxidation affects the movement of the spool; exhaust valve of the exhaust system is very reliable, in the factory before each experiment through the exhaust valves and pressure seal test. Individual components are precision cast, resulting in a perfect assembly. 3). As long as the system pressure, exhaust valve is continually. In this paper.
B, the main use of:
Automatic exhaust valve for: an independent heating system; heating system; heating system of floor radiation heating system; solar energy; heat pump system; central air conditioning; heating boiler etc..
The work principle of C, automatic exhaust valve
When there is air, gas accumulation in upper part of the exhaust valve, in vivo accumulation of air bubbles to float with the water level dropped, so open the exhaust piston; gas drained, the water level rises, float will also rise, closing the exhaust piston. Such as tightening the valve body lateral cap, exhaust valve to stop the exhaust, in general, the valve cap should be in the open state.
