[0020] The technical scheme of the utility model will be further explained below in combination with the drawings of the specification:

[0021] As Figures 1 to 3As shown, the adaptive pressure water meter sealing test device includes a servo motor 1, a screw jack 3, a reducer 2, a support plate 4, a guide frame 5, a telescopic water pipe 6, an upper plate 7, a lower plate 8, a base 9, a power mechanism 10, a water tank 11 with a high-frequency booster pump, and several guide columns 12. The servo motor 1, reducer 2, and screw jack 3 are all mounted on the support plate 4. The servo motor 1 drives the reducer 2 to rotate, and the reducer 2 drives the screw jack 3 to move up and down. The screw jack 3 is connected to the guide frame 5 via a transmission connection. The upper plate 7 is fixedly connected to the guide frame 5. One end of the telescopic water pipe 6 is connected to the upper plate 4. The upper plate 7 is connected to the lower plate 8, and the other end of the telescopic water pipe 6 is connected to the water tank 11 with a high-frequency booster pump. A valve 61 is installed on the telescopic water pipe 6. The power mechanism 10 is installed on the base 9, and the base 9 is installed inside the water tank 11 with a high-frequency booster pump. The lower plate 8 is slidably connected to the base 9. The power mechanism 10 is connected to the lower plate 8, and the lower plate 8 is connected to the water tank 11 with a high-frequency booster pump. Both the upper plate 7 and the lower plate 8 are provided with water passage holes 71. The guide frame 5 is sleeved on the guide column 12. One end of the guide column 12 is installed on the support plate 4, and the other end of the guide column 12 is installed on the base 9.

[0022] like Figure 1 As shown, there are four guide columns 12, the power mechanism 10 is a telescopic cylinder, and the guide frame 5 is X-shaped.

[0023] like Figure 2 As shown, the base 9 is provided with a sliding groove 92, and the bottom of the lower plate 8 is provided with a slider 81, which is slidably connected to the sliding groove 92.

[0024] like Figure 3 As shown, the lower plate 8 is also provided with a water pipe 82, and the base 9 has an opening 91. One end of the water pipe 82 is connected to the water passage hole 71 located on the lower plate 8, and the other end of the water pipe 82 is inserted into the opening 91 and connected to the water tank 11 with a high-frequency booster pump.

[0025] like Figure 1 As shown, the upper plate 7 and the lower plate 8 are both circular, and the support plate 4, guide frame 5, upper plate 7, lower plate 8, and base 9 are distributed from top to bottom.

[0026] Working principle:

[0027] like Figures 1 to 5As shown, the water meter 88 is vertically placed on the lower disc by hoisting at the empty position, then the telescopic air cylinder drives the lower disc 8 to slide along the chute 92 to the position right below the upper disc 7, then the servo motor 1 drives the speed reducer 2 to rotate, the speed reducer 2 drives the screw lifter 3 to move downward, the screw lifter 3 drives the guide frame 5 to move downward, since the upper disc 7 is fixedly connected with the guide frame 5, the upper disc 7 moves downward along with the guide frame 5, so that the upper disc presses the water meter, thereby clamping the water meter by the upper disc and the lower disc. Since the clamping force is adjusted according to different models of water meters by torque control of the servo motor, the force on each model of water meter is reasonable, the water meter is not sealed due to too small clamping force, and the water meter is not damaged due to too large clamping force. One end of the water meter is communicated with the water passage hole of the upper disc, and the other end of the water meter is communicated with the water passage hole of the lower disc, at this time, the high-frequency booster pump and the valve 61 are opened, the water tank 11 is high-pressure water through the water passage 82 to the water passage hole of the lower disc through the high-frequency booster pump, thereby high-pressure water to the water meter, the water in the water meter is communicated to the upper disc through the water passage, and the water in the upper disc is transported back to the water tank 11 through the telescopic water pipe 6, thereby circulating water, so that water resources are not wasted, the air in the water meter is exhausted, and after a period of water passage, the air in the water meter is completely exhausted, at this time, the high-frequency booster pump and the one-way valve are closed, at this time, whether the water meter leaks is observed, if the water meter leaks, the water meter has poor sealing performance, and if the water meter does not leak, the water meter has good sealing performance.

[0028] The utility model is applicable to mechanical water meter, ultrasonic water meter and electromagnetic water meter with DN50, DN100, DN125, DN150, DN200 and DN250 caliber.

[0029] The utility model can be applicable to the sealing test of different models of water meters, so the application range is wide, the test operation is simple, the working efficiency is high, and the accuracy of the test result is higher, the water tank of the utility model is provided with a high-frequency booster pump, so that the boosting process is continuous, stable and reliable, the utility model is convenient to install, only needs to be hoisted at the empty position and vertically installed on the lower disc, and pushed to the position right below the upper disc by the telescopic air cylinder.
