The device is arranged on a pipeline 2 which is easy to generate a water hammer effect, when normal water flows, under the action of water pressure, the water pressure generates acting force on a valve plate 303, so that the valve plate 303 moves to be separated from a valve seat 1, water flows into the downstream of the pipeline 2 from between the valve plate 303 and the valve seat 1, the valve plate 303 moves to drive a control rod 302 to move, the control rod 302 slides on a fixed plate 301, a control spring 304 is compressed, meanwhile, the control rod 302 drives a friction piston 402 to move in a friction cylinder 401, the friction piston 402 presses gas in the friction cylinder 401, an electromagnetic valve 404 is opened, under the action of an air duct 403, the gas enters the upper part of a water storage tank 501, the gas pushes a pressing piston 602 to move in the water storage tank 501, the pressing piston 602 moves to the positions of a water inlet pipe 502 and a water outlet pipe 503, the electromagnetic valve 404 is closed, the communication between the water storage tank 501 and the friction cylinder 401 is disconnected, and the water storage space in the water storage tank 501 is reduced, the water entering the water storage tank 501 is forced to be less, and the normal water flow is ensured;
At this time, water flows from the valve seat 1 into the pipe 2, and the water flows downstream of the pipe 2 through the fixing plate 301, the outside of the friction cylinder 401, the mounting plate 701, the water collecting cylinder 802, and the water flow passage 903;
When the liquid suddenly stops, such as the pump suddenly stops, the electromagnetic valve 404 is opened because the valve plate 303 is not subjected to the action of water pressure, the valve plate 303 and the valve seat 1 are slowly closed under the action of the control spring 304 because the control spring 304 needs to restore the original state, at the moment, the friction piston 402 rubs and retreats in the friction cylinder 401 to consume energy, at the moment, the gas in the water storage tank 501 enters the friction cylinder 401 to cause the gas in the friction cylinder 401 to gradually increase until the valve plate 303 and the valve seat 1 are completely closed, the electromagnetic valve 404 is closed, at the moment, the gas at the upper part of the water storage tank 501 is reduced to cause the extruding piston 602 to move upwards to force the water storage space in the water storage tank 501 to increase until the contact plate 603 moves to the pressing head 1103, and the water storage preparation work is completed;
The water flow flows back to impact the water diversion plate 901 and the arc plate 902 at first, so that the water diversion plate 901 disperses the water flow, the water flow is dispersed into small strands, the impact force of the water flow is reduced, at the moment, the movement of the water collection cylinder 802, the connecting plate 801, the pulling rod 702, the pulling spring 704, the limiting plate 705 and the baffle 703 is limited due to the action of the mounting plate 701 and the limiting plate 705, then the water flow passes through the water flow channel 903 and the water through hole 904, the water flow enters the water collection cylinder 802 and flows back to the water storage tank 501, at the moment, when the water flow still generates larger impact force, the water flow enters the water storage tank 501 through the water inlet pipe 502, so that the water flow with the impact force is led into the water storage tank 501 for storage, the buffer action of the water flow is realized, and the impact of the water flow is further reduced;
Since the water in the water storage tank 501 is stored with the water in the water storage tank 501 and needs to be led out into the pipeline 2, during normal water supply, the friction piston 402 is forced to move in the friction cylinder 401 due to the opening action of the valve plate 303, so that the gas in the friction cylinder 401 enters the upper part of the water storage tank 501, and the extrusion piston 602 extrudes the water in the water storage tank 501, so that a part of water flow can be led out, but the water flow cannot be led out completely, and the water storage capacity of the water storage tank 501 is easy to be reduced;
When the valve plate 303 is opened, due to the arrangement of apertures at two ends of the water collecting cylinder 802, namely, the aperture of the upstream section of the water collecting cylinder 802 is large, the aperture of the downstream section of the water collecting cylinder 802 is small, water flow enters the water collecting cylinder 802 to be converged and cannot pass through quickly after being released, so that the water flow generates acting force on the water collecting cylinder 802, the water collecting cylinder 802 generates displacement to move downwards, the water collecting cylinder 802 drives the connecting plate 801 to move, the connecting plate 801 drives the pulling rod 702 to move, the pulling rod 702 moves forwards under the action of the mounting plate 701, the pulling rod 702 drives the baffle 703 to move, at the moment, the pulling spring 704 stretches, the pulling rod 702 moves to drive the straight rack 1003 to move, the straight rack 1003 drives the transmission gear 1004 to rotate, the shaft 1002 is forced to rotate, the shaft 1002 drives the threaded rod 1101 to rotate, under the guiding action of the supporting plate 1001, the threaded rod 1101 drives the connecting rod 1102 to move downwards, and the connecting rod 1102 drives the pressing head 1103 to move towards the contact plate 603 until the pressing head 1103 presses the contact plate 603 to a reasonable position, the contact plate 603 drives the pressing rod 601 to move, the rod 601 drives the pressing piston 602 to move until the pressing piston 602 to the pressing piston 602 moves to the position of the water outlet pipe 503 to be communicated with the water outlet pipe 503 and the water outlet pipe 501 is completely extruded in the water storage tank 2 through the water outlet pipe 2;
