[0029] Reference Figure 1 and Figure 2The utility model provides an embodiment: a high-pressure water pressure tester, including a box body 1, a water tank 6 is fixedly connected to the inner top of the box body 1, a water suction pipe 7 is fixedly connected to the front side of the water tank 6, the front end of the water suction pipe 7 is fixedly connected to the input end of the booster pump 8, the output end of the booster pump 8 is fixedly connected to the outlet pipe 9, the right end of the outlet pipe 9 is fixedly connected to the high-pressure tank 10, the right side of the high-pressure tank 10 is fixedly connected to the delivery pipe 12, the outside of the delivery pipe 12 is fixedly connected to the pressure relief valve 13, the right side of the pressure relief valve 13 is fixedly connected to the inner of the box body 1 On the right side of the part, an electric valve 15 is fixedly connected to the outside of the delivery pipe 12, the left end of the delivery pipe 12 is fixedly connected to the top of the transparent box 19, and a test assembly is fixedly connected to the top of the high-pressure tank 10. The test includes a pressure sensor 11, which is fixedly connected to the top of the high-pressure tank 10. The pressure sensor 11 is electrically connected to the tester body 2, and the tester body 2 is fixedly connected to the top of the box body 1. Support plates 16 are fixedly connected to both sides of the bottom of the high-pressure tank 10, and the support plates 16 are fixedly connected to the inner bottom of the box body 1.

[0030] The water resources inside the water tank 6 are sucked out and the pressure is increased by the booster pump 8, and the water enters the high-pressure tank 10 through the water outlet pipe 9, and then the test water impacts the test piece through the delivery pipe 12. The tester body 2 is electrically connected to the pressure sensor 11 and the booster pump 8, and the tester body 2 receives the real-time water pressure information to control the booster pump 8 switch.

[0031] Reference Figure 1 , Figure 3 and Figure 4 The booster pump 8 is fixedly connected to the inner bottom of the box body 1, the inner bottom of the transparent box 19 is fixedly connected with a guide plate 21, the rear side of the transparent box 19 is fixedly connected with a return pipe 17, the left end of the return pipe 17 passes through the box body 1 and is fixedly connected with a water tank 6, the front side of the box body 1 is rotatably connected with a first transparent door 5, the front side of the first transparent door 5 is fixedly connected with a handle 4, the top of the box body 1 is fixedly connected with an operating table 18, and the top of the operating table 18 is fixedly connected with a transparent box 19.

[0032] The booster pump 8 is used to boost the water pressure to reach the high pressure required for the test. The guide plate 21 is used to guide the water resources after the test to flow to the return pipe 17 through the guide plate 21, and then to the inside of the water tank 6 through the return pipe 17, completing the water recycling and greatly improving the practicality of the device. The first transparent door 5 is opened by the handle 4.

[0033] Reference Figure 1 The four bottom corners of the operating table 18 are fixedly connected with supporting legs 3, a rotating wheel 14 is arranged outside the pressure relief valve 13, the rotating wheel 14 penetrates and is rotatably connected to the right side of the box body 1, and a second transparent door 20 is rotatably connected to the front side of the transparent box 19.

[0034] The supporting legs 3 are used to support the operation of the operating table 18. Before the test, the gas in the high-pressure tank 10 and the delivery pipe 12 is discharged through the pressure relief valve 13. The rotary wheel 14 is used to drive the pressure relief valve 13. The transparent box 19 is convenient for observing the test process. The second transparent door 20 is used to open the transparent box 19 and place the object to be tested.

[0035] Working principle: When using the device, first add a certain amount of water source to the water tank 6, and then turn on the tester body 2. At this time, the pressure sensor 11 detects that the water pressure in the high-pressure tank 10 is relatively low, and the tester body 2 displays the real-time water pressure on its display screen and controls the booster pump 8 to work. The booster pump 8 increases the pressure of the water source with relatively low water pressure in the water tank 6, so that the water pressure of the water source flowing into the high-pressure tank 10 through the outlet pipe 9 is relatively high. The high-pressure tank 10 itself has the ability to withstand high pressure, and due to the temporary water storage and buffering effect of the high-pressure tank 10, it can effectively prevent the real-time water pressure from exceeding the maximum water pressure allowed by the test. After the real-time water pressure in the high-pressure tank 10 is gradually stabilized, the water source with higher water pressure is discharged through the delivery pipe 12 and impacted on the test piece to be tested. The test piece is tested inside the transparent box 19. The test water after the test flows into the return pipe 17 through the guide plate 21, and flows back to the inside of the water tank 6 through the return pipe 17 to complete the water circulation, which can ensure the constant water pressure during the test and the recycling of test water.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
