When the opened valve is suddenly closed, water flow generates a pressure on the valve and the pipe wall, mainly the valve; because the pipe wall is smooth, the follow-up water flow quickly reaches the maximum under the action of inertia and generates a destructive effect, namely a water hammer effect in water conservancy, namely a positive water hammer; this factor is considered in the construction of water conservancy pipelines, and on the contrary, after a closed valve is suddenly opened, a water hammer, called a negative water hammer, is also generated, and certain destructive power is also generated.

Therefore, it is urgently needed to develop a device capable of replacing a pressure stabilizing valve and eliminating pipeline vibration, and the problems that the pipeline is easy to damage due to small flow of pipeline vibration water and the water hammer effect are solved.
