In this embodiment, the pipe 56 is made of PE, when water in the pipe 56 flows normally, the abutting block 60 seals the water inlet end of the parallel channel 66 and the water inlet end of the transition channel 65, the first spring 62 is in a stretched state, water in the pipe 56 flows from the water inlet end of the water channel 64, the micro driving member 57 is a micro driving motor, when the valve of the pipeline is opened or closed, the controller connected with the micro driving member 57 controls the micro driving member 57 to act, so as to drive the movable rod 58 to move towards the left side, under the action of the restoring force of the first spring 62, the first slider 61 is driven to move upwards along the transition channel 65, at this time, the abutting block 60 does not seal the water inlet end of the transition channel 65 and the water inlet end of the parallel channel 66, at this time, part of water passing through the water channel 64 flows into the parallel channel 66 through the water inlet end of the transition channel 65, and then flows out of the water diversion channel 67 from the inclined arrangement, so that the pressure effect of the pipeline is slowed down, and the water flow effect in the pipeline 64 is effectively slowed down.

When part of the water in the water passing channel 64 flows into the parallel channel 66 through the water inlet end of the transition channel 65, the moving block 69 is pushed to slide in the parallel channel 66 under the action of water pressure, so that the sliding block does not seal the water diversion channel 67, the water diversion channel 67 is utilized for diversion, in addition, when the moving block 69 moves, the connecting rod 70 can be propped to slide, when the connecting rod 70 is propped to slide, as the fourth inclined plane and the third inclined plane are mutually matched, the connecting rod 70 moves towards the direction of the vertical rod 73, the end part of the vertical rod 73 is propped against the vertical channel 71, the vertical rod 73 is utilized to effectively block the water in the water passing channel 64, the flow speed of the water in the water passing channel 64 is reduced, and the damage of the flowing water to a pipeline is effectively slowed down; when the end of the vertical rod 73 slides out of the vertical channel 71, the baffle 74 slides out along with the end, water impacts the baffle 74, and the baffle 74 can split and reduce the flow velocity of the flowing water, so that the damage of the flowing water to the pipeline is slowed down, and the water hammer effect is prevented. When the vertical rod 73 is entirely located in the vertical channel 71, the second spring 75 is in a natural state (i.e. an uncompressed or stretched state), and when the connecting rod 70 abuts against the vertical rod 73 and partially slides out of the vertical channel 71, the second slider 76 slides downward in the second side groove 72, and then stretches the second spring 75.

When the pipeline valve is opened or closed, the subsequent water flow continues to move forwards due to inertia, the front water flow is blocked, the backward reverse movement is performed, the water flow in the two directions merges to cause larger extrusion to the pipeline, at this time, a part of the water flow flows back into the backflow pipe 77 in the backflow process, the part of the backflow water can prop against the movable sealing member 80, so that the movable sealing member 80 moves towards one end far away from the limiting body 79, the third spring 81 is compressed, then the backflow water flows through a gap between the movable sealing member 80 and the limiting body 79 and then passes through the through hole 84, the third spring 81 can offset the distance of the backflow water, the water passing through the through hole 84 flows through the flow hole 78 to the buffer space 83, then the water entering the buffer space 83 can prop against the sealing block 87, the sealing block 87 moves in the buffer space 83, then compresses the fourth spring 88, so as to offset the backflow pressure, and meanwhile, the backflow water can flow into the buffer space 89 through the drain hole 89, and finally flow back through the backflow water through the backflow plate 90 to the backflow water flow-through the buffer plate 64, and the backflow water can flow back through the flow-through the buffer plate 64.

In addition, the other part of the return water enters the water channel 64 to collide with the subsequent inertial water flow, the pressure suddenly changes, longitudinal pressure is generated on the water channel 64 and the buffer plate 90 is extruded, the fifth elastic piece 91 is compressed after being stressed, and the fifth elastic piece 91 can effectively eliminate the longitudinal pressure through elastic deformation, so that the water flow becomes stable, and the pressure suddenly changes of the water flow in the pipeline caused by the water hammer effect are greatly eliminated through the structure of transverse, longitudinal and pressure relief, and the impact of the water hammer effect on the pipeline wall is reduced.

The above disclosure is only a preferred embodiment of the present invention, and it should be understood that the scope of the invention is not limited thereto, and those skilled in the art will appreciate that all or part of the procedures described above can be performed according to the equivalent changes of the claims, and still fall within the scope of the present invention.
