Description

Technical Field

[0001] The utility model relates to the technical field of a positioning device for quickly separating a fixed ball valve, in particular to a positioning device for quickly separating a fixed ball valve. Background Art

[0002] With the progress of the times, the application scope of fixed ball valves is becoming more and more extensive, but the separation of fixed ball valves is still inconvenient, so auxiliary tools are needed to help make the separation of fixed ball valves more convenient. The fixed ball valve quick separation positioning device helps the ball valve to be quickly disassembled and assembled by limiting the position of the fixed ball valve.

[0003] According to the existing Chinese patent CN 217951438 U, a positioning device for quick separation of a fixed ball valve includes a support plate, and the surface of the support plate is provided with four groups of jacks and two groups of grooves, and two groups of limit strips are inserted into the four groups of jacks. The limit strips fix the fixed ball valve body to the surface of the support plate, and there is no need to add additional structures to the fixed ball valve body. Gears and two groups of racks are installed inside the grooves, and the two groups of racks are meshed with the gears. A plug rod is fixedly connected to the end of the rack, and the plug rod is inserted into the corresponding jack after passing through the groove. A lever is provided on the side of the plug rod. The lever is moved to control the plug rod to separate from the jack, so that the limit strip can be disassembled labor-savingly and conveniently, thereby facilitating the disassembly and assembly of the fixed ball valve body. The height of the support plate can be adjusted by twisting the threaded rod to ensure a stable support effect for the fixed ball valve body. Although the device allows the fixed ball valve body to be fixed on the surface of the support plate by using limit strips, plug rods and holes, the number and positions of the holes on the limit strips limit the size of the fixed ball valve body that can be used with the device to a certain extent, and the device requires manual rotation of the threaded rod to adjust the height of the support plate, and also requires manual adjustment of the limit strip to firmly fix the ball valve body. The device consumes too much manpower, is inconvenient to operate, and has few applicable scenarios.

[0004] Therefore, it is necessary to provide a positioning device for quickly separating a fixed ball valve to solve the above technical problems. Utility Model Content
