Description
use
 
The valve is designed in the pump outlet or in the high-pressure water distribution pipeline to use a large amount of air in the conduit to enhance the efficiency of the water pipe and the pump, and the valve can be quickly opened when a negative pressure occurs in the pipe. Inhalation of a large amount of air to damage the storage line due to negative pressure
 
Principle of action
 
When the water injection starts 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, such as 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 in the pipe is empty or when a negative pressure is generated in the pipe, the float ball is lowered at this time, leaving the sealing surface, and a large amount of 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)
