Description

Technical Field

[0001] The utility model relates to the technical field of pipeline valve maintenance, in particular to a fixing device for pipeline valve maintenance. Background Art

[0002] Pipeline valves are control components in fluid transportation systems. They have functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief. From simple mechanical shut-off valves to electronically controlled valves used in complex automatic control systems, there are many types and specifications of valves. Valves are extremely common in various liquid and gas transportation pipelines, and the usage is also very large, resulting in a large number of valves that need maintenance.

[0003] In the prior art, a patent document with the announcement number CN220197472U proposes a fixing device for valve maintenance, comprising a main board, two brackets fixedly mounted on the main board, two movable plates disposed between the two brackets, a clamping plate rotatably disposed within each movable plate, the space between the two clamping plates being used to accommodate the valve body, and connecting blocks being fixed on both sides of each movable plate. A drive structure is mounted on the bracket, the drive structure comprising a second motor disposed at one end of the bracket, the output end of the second motor passing through one side of the bracket and fixedly connected to a bidirectional screw, a movable block being threadedly connected to the bidirectional screw, the bidirectional screw being driven to rotate by the second motor, so that the two movable plates on the bidirectional screw can move toward each other, thereby clamping and fixing the valve body. When the angle of the valve body needs to be rotated, the first motor only needs to be started, and the clamping plates driven by the first motor are rotated, thereby driving the valve body to rotate a certain angle, making it convenient for the user to inspect, disassemble, and repair the valve body.

[0004] In order to solve the problem that the existing valves are inconvenient to fix during maintenance, the existing technology adopts a method of providing a clamping mechanism to assist in fixing the valve. However, the device can only fix valves of fixed sizes during use. At the same time, it is inconvenient to limit the valve when adjusting the valve angle, which easily causes the valve to rotate during maintenance, thereby reducing the practicality of the valve fixing device.
