Description

Technical Field

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

[0002] Valves are pipe accessories used to open and close pipes, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. During valve production, a testing device is required to test the air tightness of finished valves. Only after the test is qualified can the subsequent storage operation be carried out.

[0003] Traditional testing devices, when testing the air tightness of a valve, usually place the valve on a placement table, use a push rod to make the air supply disk contact with the valve to supply air, and detect the air tightness of the valve by observing the air pressure in the air supply equipment. However, when the air supply disk contacts the valve, the staff needs to manually fix the valve to prevent the valve from moving during testing, which requires the staff to fix the valve while performing the testing operation, increasing the staff's work intensity. At the same time, there is still a gap between the surface of the valve and the air supply disk and the placement table, which causes deviations in the valve test results and reduces the work quality of the testing device.

[0004] According to a sealing detection device for valve production provided by publication number: CN220182677U, two lifting components are symmetrically arranged on the detection platform, and the lifting components include a bottom plate, a bearing plate, a lifter and a slide groove. The bottom plate is located at the bottom end of the cabinet and is fixed on both sides of the detection platform, the lifter is fixed at the upper end of the bottom plate, and the bearing plate is located at the upper end of the lifter. The lifting component at the rear end of the detection platform can facilitate valve loading, and the lifting component at the front end of the detection platform can facilitate valve unloading. A valve is placed on the bearing plate and the lifter is started. At this time, the lifter will drive the bearing plate to rise, and then the valve will rise, and then the valve can be moved from one end of the bearing plate to the detection platform. This process does not require manual movement of the valve, which can save labor and improve the loading efficiency of the valve.

[0005] According to the detection device introduced above, when the air supply disk contacts the valve, the staff needs to manually fix it to prevent the valve from moving during detection. As a result, the staff needs to fix it while performing the detection operation, which increases the staff's work intensity. At the same time, there is still a gap between the surface of the valve and the air supply disk and the placement table, which causes deviations in the detection results of the valve and reduces the working quality of the detection device. Therefore, we need to propose a detection device for valve production. Utility Model Content
