Exhaust Valve classification and selection-Shanghai Yibo Luo Fluid Control Valve Co., Ltd.
[Product introduction]]:
exhaust Valve is an essential auxiliary component in the pipeline system. It is widely used in the highest point of the pipeline, elbow or place with closed gas to remove the gas in the pipeline to dredge the pipeline and achieve normal work. If this valve is not installed, the pipeline will have air resistance at any time, which will make the water capacity of the pipeline fail to meet the design requirements. Secondly, power failure occurs during the operation of the pipeline, if negative pressure occurs in the pump stop pipeline in time, it will cause vibration or rupture of the pipeline. Air is quickly sucked into the pipe at intake valve to prevent vibration or rupture of the pipe.
[Working Principle]]
: When the water enters the pipeline, the plug stops at the lower part of the locating rack to exhaust a lot. When the air is exhausted, the water enters the valve to float the ball, and the transmission plug ends to close and stop the exhaust. During normal operation, the pipeline will naturally produce a small amount of gas, which will accumulate in the upper part of the pipe. To a certain extent, the water level in the valve drops, and the floating ball drops along with the water. The gas is discharged from the small hole. If power failure occurs, when the pump is stopped, negative pressure will appear at any time when the water flow in the pipeline is empty. The floating ball drops smoothly. Open the small hole and drive the large hole to carry out a large amount of air intake to ensure the safety of the pipeline.
