Sewage composite exhaust valve Overview: Sewage composite exhaust valve for sewage pipe on the highest point or a place to close the gas, by excluding the gas pipe to clear the pipeline to achieve normal work. If the exhaust valve is not installed, the pipe may be hindered at any time, which is the design capacity of the pipe to reach the water discharge capacity. Secondly, there is power failure during the operation of the pipe, if the pump is stopped in time, negative pressure will cause pipe vibration or rupture, The valve quickly draws air into the tube to prevent the tube from vibrating or rupturing. Sewage composite exhaust valve principle of action: When the sewage pipe in operation, the sewage compound exhaust valve flap parked in the lower part of the positioning frame, a large number of exhaust, when the air row is exhausted, the sewage into the valve, the ball float, Drive the flap to close and stop venting. Internal operation of the tube will naturally produce a small amount of gas, these gases will be concentrated to the upper part of the tube, to a considerable extent, the valve drops in the water, the float down the water, gas from the holes discharge. In the event of power failure, stop pump, negative pressure occurs at any time when the water flow in the pipe is empty, the float moves downwards, and a large hole is opened to drive a large amount of gas to ensure the safety of the pipe. Note: Exhaust valve pressure during use can not be less than 0.02Mpa, such as less than 0.02Mpa, exhaust valve prone to leakage. Must be equipped with a valve as a maintenance.
