there are often customers inquiry what is our working principle of the exhaust valve manufacturer? To tell you installed on the exhaust valve valve used in pipes of the high point of the gas in the pipeline, when the water pipe line have gas overflow, gas will be gathered up along a tube into the vent Industrial Valves cavity in the upper portion of the exhaust valve, with the increasing of the gas inside the valve, pressure rise, when gas pressure is greater than the system pressure, the gas can make the cavity of the water drops, float with the water level drops, open the vent; Gas, after the water level rise, buoy also rose, close the vent. Likewise, when negative pressure is formed in system, valve chamber in the water drops, vent open, because the outside atmospheric pressure is greater than the system pressure, so the atmosphere through the vent into the system, avoid the harm of negative pressure. Existing composite exhaust valve, the air outlet is often only one, occurring in the process of water gas, all need from & middot; When the discharge outlet, and when the water pipe LuZhengChang conveyor don't need a large number of exhaust, only a small amount of air gathered within the Industrial Valves, the composite exhaust vent valve will continue to lead to the stainless steel ball float frequently make lifting exhaust gesture, which reduces the service life of the stainless steel ball float.
