How can the fast closing noise check valve prevent water hammer?
It is recommended to see the principle of water hammer in fluid mechanics and the structure and principle of the check valve. These are not a few words to talk about, you can understand, and the important thing is to study your own! Only in this way can I really understand.
Biaoguan valve that once the pump stopped, check valve spool in the spring or other auxiliary device for double end under the action of force balance in advance to the closed position, can greatly reduce the amount of water and initial water reflux falling height, water hammer force is calculated by gravity superposition, to reduce the amount of water is equal to the reduced gravity, but fell short height reduces the inertia time is relatively reduced speed, and can prevent the formation of destructive or reduce water hammer water hammer.
Quick closing silencing check valve prevents water hammer principle:Once the pump stopped, check valve spool in the spring or other auxiliary device for double end under the action of force balance in advance to the closed position, can greatly reduce the amount of water and initial water reflux falling height, water hammer force is calculated by gravity superposition, reduce the amount of return equal to the reduction of gravity. Fall short height reduces the inertia time is also relatively reduced speed, and can prevent the formation of destructive or reduce water hammer water hammer.Quick closing and silencing check valve and silencing check valve is to rely on the flow of the medium itself automatically open and close the valve, backflow valve to prevent the media, also known as check valve, check valve, silent check valve reflux valve, and back pressure valve. The check valve belongs to an automatic valve, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium. The check valve can also be used to provide a supply to the auxiliary system where the pressure may rise above the system pressure. The check valve can be mainly divided into swing check valve (rotating by gravity center) and lift check valve (moving along the axis).
