Description

Technical Field

[0001] This utility model relates to the field of valve operating tools for nuclear power plants, and in particular to a multifunctional valve operating tool. Background Technology

[0002] In the daily work of nuclear power plants, on-site personnel frequently need to use wrenches to operate valves in the process system. When encountering multiple valve operation tasks, it is often necessary to carry multiple valve operating wrenches of different sizes or types. For example, different sizes of wrenches are needed depending on the size of the valve; "F" type wrenches are needed for valves with openwork valve handles and "I" type valve handles; "claw" type wrenches are needed for valves with openwork valve handles; copper wrenches are needed for valves in hydrogen-related systems; and plastic-coated wrenches are needed for valves in hazardous chemical systems. These valve operating wrenches are all made of metal, which makes it heavy for workers to carry and inconvenient. Moreover, carrying multiple operating wrenches at the same time is prone to loss, creating a problem of foreign objects in the plant. Utility Model Content

[0003] This utility model provides a multifunctional valve operating tool to solve the problem in the prior art where operators carry multiple wrenches, resulting in heavy loads and inconvenience.

[0004] The technical solution of this utility model is as follows:

[0005] This utility model proposes a multifunctional valve operating tool, which includes: an operating handle, a wrench storage compartment, several short-handled wrenches, and a locking bolt. The upper end of the operating handle is connected to several short-handled wrenches through the locking bolt. The force direction of the short-handled wrenches is perpendicular to the locking bolt to prevent the locking bolt from loosening due to the force of the short-handled wrenches. A wrench storage compartment is provided below the locking bolt.

[0006] In some embodiments, the wrench storage compartment has openings on both sides, and the wrench storage compartment is used to store short-handled wrenches.

[0007] In some embodiments, the short-handle wrench includes an "F"-shaped short-handle wrench and a "claw"-shaped short-handle wrench. The "F"-shaped short-handle wrench is used to operate a hollow valve handle and a "I"-shaped valve handle, while the "claw"-shaped short-handle wrench is used to operate a star-shaped valve handle.

[0008] In some embodiments, the "F"-shaped short-handle wrench includes: a stainless steel "F"-shaped short-handle wrench, a copper "F"-shaped short-handle wrench, and a plastic-coated "F"-shaped short-handle wrench. The copper "F"-shaped short-handle wrench is used to operate valves in hydrogen-related systems of nuclear power plants, and the plastic-coated "F"-shaped short-handle wrench is used to operate valves in hazardous chemical systems.

[0009] In some embodiments, short-handle wrenches are designed in various sizes of "F"-shaped and "claw"-shaped short-handle wrenches as needed.

[0010] In some embodiments, the operating handle is a telescopic rod with telescopic function, providing different sizes of operating torque.

[0011] The following are the beneficial effects of implementing this utility model:

[0012] This invention proposes a multi-functional valve operating tool. By incorporating multiple short-handled wrenches and a retractable operating handle, it eliminates the need for operators to carry multiple wrenches of different sizes or types. Only one multi-functional valve operating tool is required to handle valves of various sizes and types. The design, with multiple short-handled wrenches sharing a single retractable operating handle, avoids the burden on operators caused by carrying multiple long-handled wrenches. Furthermore, by aligning the locking bolt perpendicular to the force direction of the short-handled wrench, this invention prevents the bolt from loosening due to stress, thus preventing the wrench from malfunctioning.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] like Figures 1 to 5 As shown, this utility model proposes a multifunctional valve operating tool, which includes: an operating handle 6, a wrench storage compartment 7, several short-handled wrenches, and a locking bolt 8. The operating handle 6 is a telescopic rod with a telescopic function. By extending and retracting the operating handle 6, the length and torque of the operating handle can be changed, thus making it applicable to different operating spaces and providing different operating torques to make it easier for the operator to turn the wrench. Several short-handled wrenches are connected to the upper end of the operating handle 6 via the locking bolt 8. The force direction of the short-handled wrenches is perpendicular to the locking bolt 8 to prevent the locking bolt 8 from loosening due to the force applied by the short-handled wrenches. The wrench storage compartment 7 is located below the locking bolt 8, with openings on both sides for storing the short-handled wrenches. The operating handle 6 has short-handled wrenches at the upper end and the other end at the lower end.

[0021] The tool suite includes a small steel "F"-shaped short-handle wrench 1, a large steel "F"-shaped short-handle wrench 2, a "claw"-shaped short-handle wrench 3, a copper "F"-shaped short-handle wrench 4, and a plastic-coated "F"-shaped short-handle wrench 5. The "F"-shaped short-handle wrench is used to operate the openwork valve handle 9 and the "I"-shaped valve handle 11, while the "claw"-shaped short-handle wrench 3 is used to operate the openwork valve handle 10. The copper "F"-shaped short-handle wrench 4 is used to operate the openwork valve handle 9 and the "I"-shaped valve handle 11 of valves in hydrogen-related systems, and the plastic-coated "F"-shaped short-handle wrench 5 is used to operate the openwork valve handle 9 and the "I"-shaped valve handle 11 of valves in hazardous chemical systems. If needed, depending on the actual on-site work, different sizes of "F"-shaped short-handle wrenches and "claw"-shaped short-handle wrenches 3 can be added, as can "claw"-shaped short-handle wrenches 3 made of copper or with plastic coatings.

[0022] This invention eliminates the need for workers to carry multiple wrenches of different sizes or types. A single, multi-functional valve operating tool suffices to meet the operational needs of valves of various sizes and types. Its design allows multiple short-handled wrenches to share a single retractable operating handle 6, avoiding the heavy burden on workers caused by carrying multiple long-handled wrenches. Furthermore, the integration of all wrenches into a single tool solves the problem of easily losing wrenches that arises when carrying multiple wrenches.

[0023] This utility model proposes a multifunctional valve operating tool, the operation method of which includes:

[0024] Step 1: Loosen the locking bolt 8, and rotate the appropriate short-handle wrench to a position parallel to the operating handle 6 according to the valve type and size;

[0025] Step 2: Tighten the locking bolt 8, adjust the length of the telescopic operating handle 6, and use the tool to open and close the valve;

[0026] Step 3: Loosen the locking bolt 8, rotate the selected short-handled wrench into the wrench storage compartment 7, tighten the locking bolt 8, and retract the telescopic operating handle 6.

[0027] Before using this tool, such as Figure 2 As shown, a multi-functional valve operating tool includes a small steel "F"-shaped short-handle wrench 1, a large steel "F"-shaped short-handle wrench 2, a "claw"-shaped short-handle wrench 3, a copper "F"-shaped short-handle wrench 4, and a plastic-coated "F"-shaped short-handle wrench 5, all stored in a wrench storage compartment 7, with the locking bolt 8 in a tightened state.

[0028] When using this tool, such as Figure 1 As shown, when using a multi-functional valve operating tool, loosen the locking bolt 8, select a different type or size short-handled wrench according to the valve type and size, rotate the selected short-handled wrench to a position parallel to the operating handle 6, and tighten the locking bolt 8. Adjust the length of the telescopic operating handle 6 according to the actual operating space and the required operating torque.

[0029] like Figures 3 to 5 As shown, insert the selected short-handled wrench into the hollow valve handle 9, the "I"-shaped valve handle 11, or the plum blossom-shaped valve handle 10. Adjust the length of the retractable operating handle 6, and the operator holds the operating handle 6 to open or close the valve. After the operation is completed, loosen the locking bolt 8, rotate the selected short-handled wrench into the wrench storage compartment 7, tighten the locking bolt 8, and retract the retractable operating handle 6.

[0030] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
