Automatic exhaust valve works
Automatic exhaust valve: a valve installed at the highest point of the system to release air pockets generated in heating systems and water supply lines. Automatic exhaust valves are widely used in manifolds, radiators, underfloor heating, air conditioning and water supply system. Automatic exhaust valve works: When there is air in the system, the gas accumulates in the upper part of the exhaust valve, the valve gas accumulation, the pressure rise, when the gas pressure is greater than the system pressure, the gas will make the cavity surface water down, with the float Water level together, open the exhaust port; gas exhausted, the water level rise, the buoy also will rise, close the exhaust port. If you tighten the bonnet on the valve body, the vent valve will stop venting. Normally the bonnet should be open. Can also be used with the cut-off valve, easy to exhaust valve maintenance. The role of automatic exhaust valve: HVAC system and HVAC system in the operation process, the water released in the heating gas, such as hydrogen, oxygen and other adverse effects brought about by the system will damage and reduce thermal effects, such as gas can not be timely Drain will have a lot of adverse consequences. Such as: corrosion caused by oxidation; the formation of airbags in the radiator; unbalanced hot water circulation is not smooth, so that some radiators do not partially heat; noise when the pipe runs with gas; vortex phenomenon circulating pump. Therefore, the system of exhaust must be promptly discharged, we can see the important role of the use of automatic exhaust valve. More Search Keywords: exhaust valve
