[0027] When in use, four partition plates 9 are provided and arranged at intervals on the outside of the central column 8, so as to form four inspection stations on the inspection base 17.

[0033] Furthermore, a switch panel 3 is fixedly installed on the front end surface of the top box 2, a sealing ring plate 20 is arranged on the outer side of the detection base 17, and the sealing ring plate 20 is fixedly connected to the top box 2 by screws.

The setting of the ring cover 4 can block the gap between the detection base 17 and the sealing ring plate 20, reduce the dust in the air from entering the gap between the detection base 17 and the sealing ring plate 20, and improve the practicality.

[0034] Working principle: When in use, place a water meter to be tested on the placement base plate 23, and then rotate the rotating rods 27 on both sides respectively, so that the two movable plates 25 move horizontally to clamp the water meter, and then connect the first hose 5 to one end of the water meter, and connect the second hose 6 to the other end of the water meter, open the first solenoid valve 19, start the pressure pump 11, and extract the water in the water tank 14 through the suction pipe 12, and then transport it into the water meter. The water pressure is detected by the pressure sensor 21. After the pressure in the water meter reaches the specified detection value, stop the pressure pump 11 and close the first solenoid valve 19 to maintain the pressure. During the pressure maintenance process of the water meter pressure resistance test at this station, start the motor 16, drive the center column 8 to rotate, and rotate the detection base 17, and perform the pressure resistance test of the next water meter at the next station. In this way, compared with the pressure resistance test of only a single water meter at a time, the time of waiting for the water meter to maintain the pressure is saved, which is beneficial to the efficiency of the pressure resistance test of multiple water meters.
