[0024] ​In the structure, the sealing groove 7 is arranged in the inner cavity of the sealing box 3, and the piston 9 and the connecting rod 10 are arranged in the inner cavity of the sealing groove 7. When the water flow is reversed, the outer wall of the stress plate 12 is acted on, so that the connecting rod 10 and the piston 9 are driven, and the air in the inner cavity of the sealing groove 7 is compressed. Under the action of the piston 9, the impact force of the water flow is relieved.

[0025] In a preferred embodiment, the outer wall diameter of the piston 9 is equal to the inner wall diameter of the sealing groove 7, and the piston 9 is made of natural rubber.

[0026] In the structure, the piston 9 is arranged in the inner cavity of the sealing groove 7. When the stress plate 12 moves under the action of the water flow, the piston 9 moves along the inner wall of the sealing groove 7, so that the air in the inner cavity of the sealing groove 7 is compressed.

[0028] In the structure, the reset spring 11 is arranged on the outer wall of the connecting rod 10. Under the support of the reset spring 11, the piston 9 can be ensured to be in the middle position of the inner cavity of the sealing groove 7. When the water flow passes through the second water pipe 5 to the first water pipe 1, the stress plate 12 close to the first water pipe 1 side is driven by the water flow, so that the piston 9 moves to the end of the sealing groove 7. Under the action of the reset spring 11, the piston 9 is supported, so that the piston 9 can be in the middle position of the inner cavity of the sealing groove 7, so as to better compress the gas in the inner cavity of the sealing groove 7 and buffer the water flow.
