Abstract:The structure, work principle and design method of the pressure-releasing and pressure-continuous valve are introduced. This kind of valve uses piston as driver, and uses pilot valve as degenerative feedback controller. Its application shows that it have some good characteristics. It turns on rapidly; it has good pressure release effect; it removes water hammer when closed which avoiding pipe pressure fluctuating; it has steady continuous pressure, and it runs steadily.
