Composite exhaust valve

Release time：2024-03-22 Click：

Composite exhaust valve is used in pump outlet or water distribution system pipeline, used to eliminate the air accumulated in the pipeline, so as to improve the efficiency of the pipeline and pump, when the pipe once negative pressure is generated, the valve quickly sucks in the outside air to prevent the pipeline from being damaged by negative pressure. When the pipeline begins to fill with water, the valve disc is in the open position, a large amount of exhaust, when the air plays when the valve is filled with water, the float rises and drives the valve disc to close, stop the exhaust, when the water in the pipe is normally transported, if a small amount of air collects in the valve to a considerable extent, the water level in the valve drops, and the air is discharged by the small hole. When the water pump stops, the water flow in the pipe is empty or the pressure is generated in the pipe, at this time, the plug head is quickly opened, the air is inhaled, the negative pressure in the pipeline is balanced, the vacuum of the pipeline is prevented, and the safety of the pipeline is ensured.
