[0025] In actual use, the high-pressure water pump 302 passes high-pressure water into the water meter 1 through the first pipe 301, so that the auxiliary inspection personnel observe whether the water meter 1 can withstand high-pressure liquid water, and then complete the pressure resistance test of the water meter 1; the first solenoid valve 303 is mainly used to control the opening and closing of the first pipe 301.

[0026] like Figure 3 As shown, preferably, the extraction component 4 includes a second tube 401 which is connected to the upper part of the other side wall of the water tank 2 , and a high-pressure fan 402 and a second solenoid valve 403 are provided on the second tube 401 .

[0027] In actual use, after the detection is completed, the second solenoid valve 403 is opened first, and the liquid water in the water meter 1 naturally flows into the second tube 401. After a certain period of time, the high-pressure fan 402 is started to transfer the air inside the water meter 1 and the residual liquid water to the second tube 401. After a certain period of time, the second solenoid valve 403 is closed so that no liquid water will remain inside the water meter 1.

[0028] It should be noted that the high-pressure fan 402 is purchased from the market, and the structure of the high-pressure fan 402 is not described in detail here.

[0029] like Figure 4 as well as Figure 5 As shown, preferably, the clamping assembly 5 includes a mounting bar 501 arranged on the upper surface of the water tank 2, an electric telescopic rod 502 is provided on the mounting bar 501, a sliding bar 503 is provided at the output end of the electric telescopic rod 502, a sliding tube 504 is provided on the sliding bar 503, a hose 505 is provided at one end of the sliding tube 504, and the hose 505 is connected to the end of the first tube 301.

[0036] During the detection process, liquid water is extracted from the water tank 2 through the first tube 301, and finally flows back into the water tank 2 from the second tube 401, thereby realizing water circulation and water saving. Since liquid water carries dust and impurities when it returns to the water tank 2 through the water meter 1, the dust and impurities can be effectively filtered out by setting a filter plate 6, so that the water quality discharged from the first tube 301 is cleaner, and the liquid water and impurities in the water tank 2 are regularly discharged through the water replacement pipe 7, and replaced with new liquid water.
