Examples
As shown in fig. 1, screw holes are respectively formed in the left side and the right side of the water inlet end and the water outlet end of the main valve body 1, the screw hole on the right side of the water inlet end is connected with one port of the first ball valve 15 through a pipe fitting, the other port of the first ball valve 15 is connected with the pressure sensing port of the pressure relief pilot valve 17 through a pipe fitting, the water outlet port of the pressure relief pilot valve 17 is connected with one port of the second ball valve 16 through a pipe fitting, and the other port of the second ball valve 16 is connected with the screw hole on the right side of the water outlet end of the main valve body 1.
As shown in fig. 3, a diaphragm 6 is arranged at the joint of the main valve body 1 and the main valve cover 7, a diaphragm pressing plate 5 is arranged at the upper end of the diaphragm 6, a valve disc 4 is connected with the lower end of the diaphragm 6, a sealing ring groove is arranged at the lower end of the valve disc 4, a sealing ring 3 is arranged in the sealing ring groove, and the lower end of the sealing ring 3 is connected with the sealing ring pressing plate 2. The sealing ring pressing plate 2 and the valve disc 4 squeeze 3 the sealing ring. The valve cover 7 is positioned above the valve body 1, and the valve cover and the valve body are fixed together through bolts. The valve body 1 and the valve cover 7 fix the diaphragm 6 in the main valve middle cavity 9 by extrusion. The diaphragm 6, the diaphragm pressing plate 5, the valve disc 4, the sealing ring 3 and the sealing pressing plate 2 are fixed together through screws. The diaphragm pressing plate 5 is sleeved at the upper end of the middle part of the diaphragm 6, the outer side of the valve disc 4 is sleeved below the diaphragm pressing plate 5, and the valve disc 4 and the diaphragm pressing plate 5 squeeze 6 the diaphragm.
The upper end of the diaphragm pressing plate 5 is connected with one end of a spring 8, and the other end of the spring 8 is connected with the inner wall of the valve cover 7.
As shown in fig. 2, the screw hole on the main valve cover 7 is connected with the pressure stabilizing tank 14 through a pipe fitting.
The lower port of the pressure relief pilot valve 17 is connected with a screw hole on the main valve cover 7, and the pressure relief pilot valve 17 is fixed on the valve cover 7.
The screw hole at the left side of the water inlet end of the main valve body 1 is connected with one port of a tee joint 10, the second port of the tee joint 10 is connected with a ball valve III 11, one end of the ball valve III 11 is connected with a pressure gauge, the third port of the tee joint 10 is connected with one port of a needle valve 13 through a pipe fitting, and the other port of the needle valve 13 is connected with the screw hole on the main valve cover 7. The pressure gauge 12 is used to measure the pipe medium pressure.

The water hammer relief valve of the embodiment is mainly used for pipeline protection equipment for long-distance water delivery and high-rise water supply, and is arranged on a water leakage bypass, namely in parallel connection with a pipeline when the water hammer relief valve is used. The surge relief valve sets the pressure relief pilot valve 17 and surge tank 14 at the desired pressure prior to use. When the medium pressure of the pipeline rises to be higher than the set pressure, part of the medium in the main valve middle cavity 9 flows into the surge tank 14, the pressure relief valve 17 is opened, and part of the medium in the main valve middle cavity 9 flows out from the water outlet end of the pressure relief pilot valve 17. Under the action of the medium pressure, the sealing pressing plate 2 in the valve body 1 moves upwards, the valve body 1 is opened, and the medium pressure in the pipeline is released. When the pressure of medium in the pipeline is reduced to be lower than the set pressure, the high-pressure medium in the 14-type pressure stabilizing tank flows into the main valve middle cavity 9, the pressure relief pilot valve 17 is closed, the medium in the pipeline flows into the main valve middle cavity 9 through a pipe fitting, the sealing pressing plate 2 in the valve body 1 moves downwards under the acting force of the medium, and the valve body 1 is closed.
In the use process of the water hammer relief valve, when the pressure of a pipeline medium suddenly rises and rapidly exceeds the set pressure, the relief pilot valve 17 is opened in time rather than in the past. A part of the medium in the main valve middle chamber 9 can flow into the 14 surge tank, so that the valve body 1 can realize a part of opening and release a part of pipeline pressure. Then the pressure relief pilot valve 17 is opened, the opening of the valve body 1 is increased, and quick pressure relief is realized. When the pressure of the pipeline medium drops to the set pressure, the 14 surge tank can rapidly supplement medium for the main valve middle cavity 9, so that the valve body 1 is rapidly closed.
