Description

Large-displacement floating ball trap valve seat

Technical Field

The utility model relates to a trap field especially relates to a big discharge capacity floater trap disk seat.

Background

Water hammer is also called water hammer. In the process of conveying water (or other liquid), the flow speed is suddenly changed and the pressure fluctuates greatly due to the reasons of sudden opening or closing of a valve, sudden stop of a water pump, sudden opening and closing of a guide vane and the like. The water hammer effect is an image saying. It is a serious water hammer generated by water flow impacting a pipeline when a feed pump is started and stopped. Because the inner wall of the water pipe is smooth, water can freely flow. When the open valve is suddenly closed or the water pump is stopped, the water flow generates a pressure on the valve and the pipe wall, mainly the valve or the pump. Because the pipe wall is smooth, the water power of the subsequent water flow rapidly reaches the maximum under the action of inertia, and a destructive effect is generated, namely the water hammer effect in water conservancy.

In the use process of the large-displacement floating ball trap, the valve on the pipeline is closed, and liquid in the pipeline flows into the trap to generate a water hammer effect, so that the large-displacement floating ball trap is damaged.

Therefore, there is a need for a large displacement ball trap valve seat that solves the above problems.
