What Is Water Hammer Effect?
Water Hammer effect refers to the phenomenon of pressure fluctuation and vibration caused by the rapid change of fluid flow in the closed pipeline system (including pump) , just like a hammer made of water. Its instantaneous pressure can greatly exceed the normal pressure, and often have destruct...Read more -
Working Principle Of Fireproof Valve
The working principle of the Fire-proof Valve is to use the temperature of easily fusible alloy to control the opening, and to close the valve by the action of gravity and spring mechanism. When the fire occurs, the flame invades the air passage, the high temperature causes the fusible alloy on t...Read more -
