Description
use
 
The valve is designed to be pumped at the water outlet or in the high-pressure water distribution pipeline to remove a large amount of air in the pipeline to improve the efficiency of the water pipe and the water hopper. When a negative pressure occurs in the pipe, the valve can quickly take in air. To ensure that the pipeline will not be damaged by negative pressure.
 
Principle of action
 
When the water is started in the tube, the floating ball stays in the open position, and a large amount of exhaust is performed. When the air is exhausted, the water floating ball in the valve body is floated to the closed position, and a large amount of exhaust is stopped, when the tube is normally transported, if any A small amount of air collects in the valve to a considerable extent, the water level in the valve drops, and the float drops, and the air is discharged from the small hole. When the water pump or the high-pressure water distribution pipeline stops sending water, when the water flow in the pipe or the negative pressure occurs in the pipe, the float ball is down, leaving the sealing surface, and the air is sucked to ensure the safety of the pipeline. (Note: The nominal pressure is 2.5Mpa. The company is equipped with a buffer.) Device)
