Hvac systems and hvac system in the process of running, the release of the water in the heating gas such as hydrogen and oxygen can be damaged by the adverse effects of system and reduce the thermal effect, these gases such as not drained in time will have a lot of bad consequences. Such as: caused by oxidation corrosion; The formation of the radiator air pocket; Hot water circulation is not smooth imbalance, make some radiator local hot; The noise of the pipeline with destiny row; Vortex air phenomena of the circulating pump. So the exhaust gas in the system must be in time, thus using the important role of automatic exhaust valve. A, characteristics: 1) Reliable performance. Use the PK - discharge device materials EP。 PK - compared with those of all known synthetic materials EP has the best performance and high reliability. PK - A much higher working temperature. Type O sealing ring to optimize material EPDM, guarantee under the high temperature type O sealing ring still has good flexibility and reliability. Exhaust valve valve core of the internal spring the use of special materials, and adopt import stainless steel, nickel plating to prevent oxidation if oxidation affect the movement of the valve core; Exhaust valve exhaust system is very reliable, each valve before they go out all through the vent experiment and pressure seal. Individual components are composed of high precision casting, so as to get a perfect assembly. 2) Only exhaust, undrained. Steam and water separation plate design with special structure, ensure no drainage during exhaust. 3) As long as the system pressure, exhaust vent valve will be continuous. B, main use: automatic exhaust Industrial Valves used in: independent heating system; The central heating system; Radiant floor heating system; The solar heating system; Heat pump system; The central air conditioning; Heating boiler, etc. C, the working principle of automatic exhaust valve when the system in the air, gathered in the upper portion of the exhaust valve, gas bubbles in the body accumulation make float along with the water level drops, so open the exhaust piston; Gas, after the water level rise, floating ball also rose, close the exhaust pistons. Such as tight body side of the bonnet, stop exhaust exhaust valve, in usually, the bonnet should be in an open position. In this paper, the keyword search: more valve product information
