Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a gate valve hardness detection device. Background Art

[0002] A gate valve is a gate plate that opens and closes. The movement direction of the gate plate is perpendicular to the direction of the fluid. The gate valve can only be fully opened or fully closed, and cannot be adjusted or throttled. The gate valve is sealed by the contact between the valve seat and the gate plate. Usually, the sealing surface is welded with metal materials to increase wear resistance. Depending on the gate plate, the gate valve is divided into rigid gate valves and elastic gate valves. During the production and processing of the gate plate, it is usually necessary to test its hardness.

[0003] An existing hardness testing device for gate valve production (publication number: CN217981126U) has at least the following disadvantages:

[0004] When the above patent is in use, the rotating disk is driven by the rotation of the servo motor, so that the material to be tested can be rotated during the testing process, and the detection head is driven by the electric hydraulic push rod to perform multiple tests on the surface of the test material. Because when testing the gate valve, the above patent needs to place the gate valve inside the placement groove first, and then clamp it and fix it with a clamping plate. The gate valve is inside the placement groove, and there is no lifting structure at the bottom of the placement groove. After testing the hardness, the tester needs to use his fingers to buckle the gate valve to take it out of the placement groove. The operation process is inconvenient and not convenient for the tester to use. Utility Model Content
