In this embodiment the relief valve 4 includes the valve body, be equipped with the annular on the valve body lateral wall, install second sealing washer 48 in the annular, second sealing washer 48 with the inner wall of the pump body 1 forms sealedly, be equipped with the cavity in the valve body, be equipped with piston 44 and third reset spring 45 in the cavity, the tip that the overflow valve 5 was kept away from to relief valve 4 is equipped with through-hole 43, the 4 lateral walls of relief valve are equipped with apopore 47, apopore 47 intercommunication cavity and the cavity of the pump body 1, the 4 inner walls of relief valve are equipped with first sealing washer 46, first sealing washer 46 with form sealedly during the piston 44 contact, the valve body orientation the tip of overflow valve 5 is equipped with the screw hole, valve rod 41 with 4 threaded connection of relief valve, the cover is equipped with second reset spring 42 on the valve body, second reset spring 42 is in between valve body and the valve housing 53.

In this embodiment, when the high pressure gun is operated, high pressure water enters the water inlet chamber 21 in the pump body 1 and then flows out along the first water path 211 and the second water path 212, because the sealing end 411 of the valve rod 41 contacts with the perforation of the valve housing 53 to form a seal due to the acting force of the first return spring 52 and the second return spring 42, water cannot enter the overflow valve 5 through the perforation, and water passes through the first water path 211 and pushes the pressure retaining valve 31 open to flow out of the water outlet pipe 3.

When the high pressure gun is shut down, the water outlet pipe 3 is closed, the pressure in the pump body 1 rises sharply, the pressure retaining valve 31 blocks the first water path 211 under the action of the spring, so that the first water path 211 is sealed, because the water pressure in the first cavity rises, when the water pressure is greater than the supporting force of the first return spring 52 and the second return spring 42, the pressure relief valve 4 moves leftwards under the action of the water pressure, then the sealing end 411 of the valve rod 41 is separated from the valve sleeve 53, the sealing of the valve sleeve 53 is released, then the water in the water inlet chamber 21 enters the overflow valve 5 through the through hole of the valve sleeve 53 and finally flows out through the overflow hole and enters the water inlet, in addition, because the button 611 of the switch assembly 61 and the first valve core 51 are on the same straight line, when the first valve core 51 moves backwards, the first valve core 51 presses the button 611 of the switch assembly 61, so that the whole circuit is closed, the switch assembly 61 is closed, the automatic shutdown function is achieved, and the energy consumption can be saved.

In addition, since the water on the left side of the relief valve 4 enters the relief valve 5 through the through hole, the water pressure on the left side of the relief valve 4 decreases, after the high pressure gun is closed, the high pressure water on the outlet pipe 3 enters the right side of the relief valve 4 through the third water passage 32, since the water pressure on the right side of the relief valve 4 is greater than the water pressure on the left side of the relief valve 4, the third return spring 45 in the relief valve 4 cannot support the piston 44, the piston 44 pushes leftward, when the side wall of the piston 44 is separated from the first seal ring 46, the sealing of the relief valve 4 is released, and the water on the right side of the relief valve 4 enters the relief valve 4 through the through hole 43, flows out of the water outlet hole 47, merges with the water on the left side of the relief valve 4, and decreases the water pressure on the right side of the relief valve 4.

This embodiment can reduce the water pressure in the pump body 1 and make the water pressure of the inside of the pump body 1 be less than the water pressure of its during operation far away, reduces the high pressure water and to the produced burden of the pump body 1, can lengthen by a wide margin the life of the pump body 1 reduces the material requirement to the high pressure rifle, also can avoid simultaneously the high pressure rifle explodes because of the high pressure water and splits, reduces the use risk, improves user's safety in utilization, and this embodiment also can make in addition there is certain water pressure difference in the pressure retaining valve 31 left and right sides, makes the sealed more reliable of this embodiment, and the pressurize is more stable.

When the gun is opened again, the high-pressure water pushes the pressure maintaining valve 31 forward, the first valve core 51 moves rightward under the action of the first return spring 52, the valve rod 41 moves rightward under the action of the second return spring 42, and after the conical inclined surface is in contact with the through hole, the valve rod 41 and the valve sleeve 53 maintain sealing again, and meanwhile, the first valve core 51 releases the pressing on the button 611 of the switch assembly 61, so that the switch assembly 61 can be automatically opened, and the maximum pressure and the pressure maintaining pressure can be adjusted by adjusting the spring force of the first return spring 52, the second return spring 42 and the third return spring 45.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification which does not depart from the functional and structural principles of the present invention is intended to be included within the scope of the claims.
