technical field

The invention relates to the technical field of valves, in particular to a water-conveying pipe cut-off valve device that is resistant to flow and overload shock.

In life, water treatment equipment is always inseparable from pipes and valves. Water hammer effect generally exists inside the pipe when the valve is closed. The water hammer effect refers to the inside of the water pipe, the inner wall of the pipe is smooth, and the water flows freely. The water flow will produce a pressure on the valve and the pipe wall, mainly the valve. Because the pipe wall is smooth, the subsequent water flow quickly reaches the maximum under the action of inertia, and has a destructive effect, which is called "water hammer effect" in hydraulics. .
