Generally, it is divided into two categories: volumetric water meters and velocity water meters. It originated in the UK, and the development of water meters has a history of nearly two hundred years. When selecting the specification of a water meter, the size and flow range of the water flow used under normal circumstances should be estimated first, and then the water meter of the specification with the most commonly used flow rate closest to this value should be selected as the first choice. A pressure resistance detection device for water meter production is a device specifically designed to test whether a water meter can work properly under high-pressure environments.

[0037] Specifically, before the device detects the water meter, the water meter is first placed on the placement component 1, and then the rotating seat 101 drives the water meter to be detected to rotate above the detection component 2. Then, under the drive of the lifting cylinder 10, the detection component 2 covers the water meter to realize the detection of the pressure resistance of the water meter.

[0038] The placement component 1 includes a rotating seat 101, and the rotating seat 101 is rotatably connected to the top surface of the main body 6.

The design of the sealing strip 102 in the sealing groove 106 enables good sealing between the detection component 2 and the placing component 1.

[0040] The implementation principle of a pressure resistance detection device for water meter production in the first embodiment of this application is as follows: In the placing component 1, the rotating motor 109 can drive the rotating base 101 to rotate on the top surface of the main body 6. Then, under the drive of the adjusting motor 111, the adjusting screw rod 108 drives the sealing block 105 to adjust the distance in the placing groove 104, and the electric telescopic rod 110 can adjust the height of the supporting block 103, facilitating the conveying of the central axes of different water meters to the same position.

The placing groove 104 is axially symmetric about the rotating base 101. When one placing groove 104 of the device detects a water meter, the other placing groove 104 can prepare for the next detection, greatly shortening the preparation work before detection and improving the detection efficiency of the water meter. Moreover, the supporting block 103 in the placing groove 104 can be adjusted up and down under the action of the electric telescopic rod 110, enabling the device to position and clamp water meters of different calibers, improving the functionality and adaptability of the device. Before the device detects a water meter, the water meter is first placed on the placing component 1, and then the rotating base 101 drives the water meter to be detected to rotate above the detection component 2. Then, under the drive of the lifting cylinder 10, the detection component 2 covers the water meter to realize the detection of the pressure resistance of the water meter.

[0041] Embodiment Two: Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 8 、 Figure 9 and Figure 10, the detection assembly 2 includes a sealing frame 204.
