The principle of the role of the exhaust valve instructions
Exhaust valve piping system is an essential auxiliary components, are widely used in the pipeline on the highest point or elbow or a place to close the gas to exclude the gas pipe to clear the pipeline to achieve normal work. Principle of action: When water enters the pipeline, the stopper stops at the lower part of the positioning frame for a large amount of exhaust gas. When the air is exhausted, the water floats into the valve to float the ball and the transmission plug closes to stop the exhaust gas. The pipe will naturally produce a small amount of gas during normal operation. The gas will gather in the upper part of the pipe. To a considerable extent, the water level in the valve will drop. The float will descend and the gas will be drained from the small hole. If there is power failure, pump stoppage and water flow in the pipe At any time there will be negative pressure, the float down the water, open the hole to drive a large number of large holes into the air to ensure pipeline safety. If the valve is not installed, the pipe will appear gas resistance at any time, so that the water capacity of the pipe will not meet the design requirements. Secondly, when the pipe runs out of power, the pipe will vibrate or rupture if there is negative pressure in time. Pai, intake valve quickly inhaled air pipe to prevent pipe vibration or rupture.
