Technical Field

[0001] The utility model relates to the technical field of valve production detection, in particular to a pressure resistance detection device for valve production. Background Art

[0002] Valves are widely used, and the requirements for valves in production are relatively strict. For manufacturers of sealing valves, they will test the valves before the finished products are shipped. Among them, pressure resistance and sealing are important indicators of whether a valve is qualified, and they need to be tested using testing equipment;

[0003] Existing testing equipment uses water or air to inject into the valve to perform pressure testing when testing valves. During the testing process, manual observation is required. For example, Patent No. CN216483776U discloses a valve pressure seal testing device, which injects high-pressure water into the test pipeline connected to the valve and then observes the valve for leakage. Manual inspection has large errors and low detection efficiency. Therefore, we propose a pressure testing device for valve production. Utility Model Content

[0004] The purpose of the present utility model is to provide a pressure resistance testing device for valve production, so as to solve the problem that the existing testing equipment proposed in the above background technology adopts the method of injecting water or air into the inside of the valve to perform pressure resistance testing when testing the valve, and manual observation of the testing process is required during the testing process. Manual testing has large errors and low testing efficiency.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a pressure-resistant testing device for valve production, comprising a testing platform, a valve body, a pipeline, a drive assembly and a clamping assembly, wherein the drive assembly is mounted at the bottom of the testing platform, and the drive assembly is mounted at the top of the testing platform. When the regulating assembly is started, the gas in the pipeline is compressed to realize valve body detection.

[0006] Preferably, the driving assembly includes a fixed plate, an electric telescopic rod and a movable block. The bottom of the detection table is fixedly connected to the fixed plate, the side of the fixed plate is installed with an electric telescopic rod, the output end of the electric telescopic rod is fixedly connected to the movable block, and the surface of the movable block is fixedly connected to a sealing ring.

[0007] Preferably, a pipe is plugged into the surface of the detection platform, the bottom end of the pipe extends to the bottom of the detection platform, and the pipe and the movable block are located at the same horizontal height.

[0008] Preferably, the clamping assembly includes a motor, a splint, a threaded block, a bidirectional screw and a slide groove. A slide groove is provided on the top of the detection platform, and a bidirectional screw is installed inside the slide groove. The surface of the bidirectional screw is threadedly connected with a symmetrical threaded block, and the threaded block is slidably connected to the inside of the slide groove. A splint is welded on the surface of the threaded block. One end of the bidirectional screw extends to the outside of the detection platform, and the outer end of the bidirectional screw is connected to the motor output end on the surface of the detection platform.

[0009] Preferably, a connection plate matching the valve body is fixedly connected to the top end of the pipeline, and a pressure sensor is installed on the inner wall of the pipeline near the connection plate.

[0010] Preferably, a PLC control panel is installed on the top of the testing platform, and the PLC control panel is electrically connected to the electric telescopic rod, the pressure sensor and the motor respectively.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model sets a pipeline on the surface of the test platform and connects it to the valve body through a connecting plate. The movable block is controlled to move in the pipeline by an electric telescopic rod at the bottom of the test platform. As the movable block moves in the pipeline, the air in the pipeline is compressed, that is, the air pressure in the pipeline increases. At the same time, the pressure sensor in the pipeline checks the air pressure in the pipeline, and the detection data is stored in the PLC control panel. According to the changes in the data detected by the pressure sensor, the pressure resistance and air tightness of the valve body can be tested. The detection is efficient and highly automated.

[0013] 2. The utility model provides a sliding groove on the surface of the test platform to install a bidirectional screw threaded connection with symmetrical threaded blocks. The bidirectional screw is driven to rotate by a motor on the surface of the test platform, which then drives the two threaded blocks closer, driving the clamping plate to clamp the valve body. It not only fixes the valve body and ensures the stability of the valve body during the pressure resistance test, but also tests the pressure resistance of the valve body surface through the clamping of the valve body by the clamping plate, thereby ensuring the detection effect of the valve body.
