KPQuick exhaust (suction) valve
Working principle:
When the pipeline is running, the floating ball stops at the bottom of the ball bowl for a large amount of exhaust. When the air inside the pipeline is exhausted, water rushes into the valve, passes through the ball bowl, and reacts with the floating ball, causing the floating ball to float and close. During normal operation of the pipeline, if a small amount of gas is concentrated in the valve to a certain extent, the water level in the valve will drop, and the floating ball will also drop, and the gas will be discharged from the small hole. If the water pump stops, negative pressure will be generated at any time, and the floating ball will descend at any time. A large amount of suction will be carried out to ensure the safety of the pipeline.
Main purpose
KP quick exhaust valveSuitable for pipelines with water as the industrial medium, it is an essential equipment for quickly removing gas from the pipeline to improve the efficiency of water transportation equipment and protect the pipeline from deformation and rupture. The valve is a cylindrical body with stainless steel floating balls and plugs inside. This valve is installed at the outlet of the pump or in the water supply and distribution pipeline to remove a large amount of accumulated air in the pipeline, in order to improve the efficiency of the water pipe and pump. Once negative pressure occurs inside the pipeline, this valve can quickly suck in air to prevent damage to the pipeline caused by negative pressure.
maincharacteristic
1. It can eliminate gas in the pipeline, reduce resistance, and save energy.
2. When the pipeline is under negative pressure, this product can quickly and automatically suck in air to prevent pipeline rupture.
3. The exhaust capacity is several times that of a regular dual hole exhaust valve.
4. The floating ball bracket is made of stainless steel, with a long service life, safety and reliability.
