The automatic exhaust valve is a very important auxiliary component in the pipeline system and is widely used in boilers, air conditioners, oil and gas, and water supply and drainage pipelines. It is often installed at the highest point or elbow of the pipeline system to eliminate excess gas in the pipeline, improve the efficiency of the pipeline and reduce energy consumption.
When there is a gas overflow in the system, because the density of the gas is smaller than that of water, the air bubbles will float up to the top of the inner wall of the pipeline. Driven by the water, the gas will climb up the pipeline and eventually gather at the highest point of the system. Automatic exhaust valves are generally installed at the highest point of the system. When the gas enters the stainless steel exhaust valve chamber, it gathers in the upper part of the stainless steel exhaust valve. As the gas in the valve increases, the pressure rises. When the gas pressure is greater than the system pressure, the gas will cause the water surface in the chamber to drop, and the pontoon will drop along with the water level, opening the exhaust port; after the gas is exhausted, the water level rises, and the pontoon will also rise and close the exhaust. mouth.By the same token, when a negative pressure is generated in the system, the water surface in the valve chamber of the stainless steel exhaust valve drops and the exhaust port opens. Since the external atmospheric pressure is greater than the system pressure at this time, the atmosphere will enter the system through the exhaust port to prevent the harm of negative pressure.If the valve cap on the body of the stainless steel exhaust valve is tightened, the stainless steel exhaust valve stops the exhaust. Under normal circumstances, the valve cap should be open.The stainless steel exhaust valve can also be used in conjunction with the partition valve to facilitate the maintenance of the stainless steel exhaust valve.
