Description

Technical Field

[0001] This utility model relates to a tool for operating valve groups. Background Technology

[0002] Currently, the traditional tools for operating manual valves in power plants are two-pronged or three-pronged iron hooks, with a single handle for operation. When using these traditional hooks, personnel exert force on the handle, which rotates the valve to open or close it. This method is relatively easy for operating valves that are low in position and few in number. However, every time the handle is rotated approximately 90 degrees, the fork must be re-inserted into the valve, requiring dozens of repetitions for a single valve to be fully open or closed. In actual power plant production, such as in bottom heating operations, where there are many valves, their positions are relatively high, and adjacent valves are closely spaced, continuing to use traditional tools not only consumes a significant amount of physical strength but also wastes considerable time, increasing unit start-up time. Furthermore, the close proximity of these valves makes it extremely easy for personnel to injure their arms during operation. Therefore, given the increasing frequency of peak shaving and start-ups / shutdowns in thermal power plants, and the increasingly frequent operation of bottom heating valves, there is an urgent need for a new type of operating tool to address these safety issues encountered in production. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned technical problems and provide a tool for operating valve groups.

[0004] The above objectives are achieved through the following technical solutions: A tool for operating valve groups, comprising four socket wrenches arranged at a 90° angle to form a spiral structure. The socket wrench includes a hollow cylindrical sleeve and a handle, the handle being welded to the hollow cylindrical sleeve, and a vertically arranged claw rod being welded to the bottom of the hollow cylindrical sleeve.

[0005] The aforementioned tool is used for operating valve groups, and the hollow cylindrical sleeve is threaded with a fixing bolt.

[0006] The aforementioned tool is used for operating valve assemblies, wherein the claw rod is a cylindrical rod. Beneficial effects

[0007] 1. This utility model allows for continuous valve operation without the need for readjustment each time, thus achieving the goals of saving physical strength, time, and safety.

[0008] 2. The hook of this utility model can be operated continuously by inserting the handwheel only once, which has the outstanding advantages of saving time, effort and safety.

[0009] 3. This utility model, by setting four socket wrenches, can adjust the connection position of the four socket wrenches to make it suitable for valves of different sizes. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 A schematic diagram of the sleeve wrench; Figure 3 This is a perspective view of the present invention in use; Figure 4 This is a top view of the present invention in use; In the diagram: 1. Fixing bolt; 2. Hollow cylindrical sleeve; 3. Hand lever; 4. Claw lever; 5. Valve. Detailed Implementation

[0011] Reference Figures 1-2 A tool for operating valve groups, comprising four socket wrenches arranged at a 90° angle to form a spiral structure. The socket wrench includes a hollow cylindrical sleeve 2 and a handle 3. The handle is welded to the hollow cylindrical sleeve, and a vertically arranged claw 4 is welded to the bottom of the hollow cylindrical sleeve.

[0012] The aforementioned tool is used for operating valve groups, wherein a fixing bolt 1 is threadedly connected to the hollow cylindrical sleeve.

[0013] The aforementioned tool is used for operating valve assemblies, wherein the claw rod is a cylindrical rod.

[0014] Working principle: Refer to Figures 3-4 The device needs to be installed first, by assembling the four socket wrenches, such as... Figure 3As shown, four socket wrenches are labeled A, B, C, and D. First, socket wrench B is at a 90-degree angle to socket wrench A, and the hollow cylindrical sleeve of socket wrench B fits onto the handle of socket wrench A. The handle is cylindrical, and the inner diameter of the hollow cylindrical sleeve of socket wrench B is slightly larger than the diameter of the handle. Socket wrench C is at a 90-degree angle to socket wrench B, and its hollow cylindrical sleeve fits onto the handle of socket wrench B. Socket wrench D is at a 90-degree angle to socket wrench C, and its... The hollow cylindrical sleeve of the hand is fitted onto the handle of the C sleeve wrench, and the fixing bolts on each hollow cylindrical sleeve are tightened. The ends of the fixing bolts will press against the handle, thus fixing the position. Then, the entire device is placed on the valve, with its claw rod passing through the middle of the valve spokes. Then, by holding the handle of the B sleeve wrench, the device is rotated to operate the valve. After rotation, the handle of the A sleeve wrench is held. In this way, continuous operation can be performed with only one insertion of the handwheel, which has the outstanding advantages of saving time, effort, and safety.
