Description

Technical Field

[0001] This utility model relates to the field of wrench technology, specifically a novel valve wrench. Background Technology

[0002] Valves are widely used in industries such as petrochemicals, power, metallurgy, and pharmaceuticals. Correspondingly, operating valves is very common in industrial work. Valves usually have a handwheel, which workers can turn to open or close the valve by hand or with the help of tools. The commonly used tool is a valve wrench, also called an F-wrench. A valve wrench is a special tool used to open and close valves. It uses the lever principle to increase the operating torque and easily turn the valve stem. Its material is mostly carbon steel, stainless steel, or alloy, and the surface is treated with electroplating, etc., to be wear-resistant and rust-proof. According to the structure, there are fixed opening, movable opening, and sleeve type, which are suitable for different valve specifications. When using it, the corresponding wrench should be selected according to the valve size to ensure that the valve stem is locked and the force is applied evenly to avoid slippage and damage to parts. It is widely used in the maintenance of valves in pipelines and equipment. It is an essential tool for operating valves in industrial production, water supply and drainage systems, etc., which can improve operating efficiency and ensure safety.

[0003] Current valve wrenches have many limitations in practical use. For example, the shape and size of valve wrenches are relatively fixed, and they are usually only applicable to valves of specific specifications and types. They may not be usable for some non-standard sized valves. Furthermore, valve wrenches require a large operating space for rotation. If the valve is installed in a narrow or compact space, it may be difficult to operate, affecting its effectiveness. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a novel valve wrench that solves the problems of valve wrenches having relatively fixed shapes and sizes, typically only applicable to valves of specific specifications and types, and potentially unusable for some non-standard sized valves. Furthermore, valve wrenches require a large operating space for rotation, which may hinder their use if the valve is installed in a narrow or compact space, thus affecting their effectiveness.

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a novel valve wrench, comprising a valve wrench, wherein an annular frame is slidably mounted on the outer surface of the valve wrench, and a wrench pliers head is fixedly mounted on the left surface of the annular frame; An auxiliary mechanism is installed on the valve wrench. The auxiliary mechanism includes a handle and a tightening bolt. Two first connecting plates are fixedly connected to the lower end of the valve wrench. A second connecting plate is rotatably installed on the inner wall of the two first connecting plates. The handle is fixedly connected to the lower end of the second connecting plate. The tightening bolt is threaded on the right surface of the annular frame. The thread of the left end of the tightening bolt penetrates into the interior of the annular frame and contacts the valve wrench. A mounting plate is fixedly installed on the lower end of the left surface of the valve wrench. A rectangular groove is opened on the lower surface of the mounting plate. A limit plate slides and inserts into the interior of the rectangular groove.

[0006] Preferably, the auxiliary mechanism further includes a sleeve that is fitted onto the outer surface of the throttle.

[0007] Preferably, a threaded rod is rotatably mounted on the upper inner wall of the rectangular groove, the threaded rod is threadedly connected to the limiting plate, and a circular hole is opened on the upper surface of the mounting plate.

[0010] Preferably, a handle is fixedly installed on the right surface of the valve wrench.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides a novel valve wrench with the following advantages: 1. This new type of valve wrench, by allowing the ring frame to slide along the valve wrench and be fixed with tightening bolts, enables the wrench head to adapt to valve handwheels of different specifications and positions. The rotatable handle can adjust the length of the valve wrench main rod. When rotating normally, it can be turned to the vertical direction for easy and rapid rotation, improving the efficiency of valve opening and closing.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 This utility model provides a new technical solution: a new type of valve wrench, including a valve wrench 1, an annular frame 3 is slidably installed on the outer surface of the valve wrench 1, and a wrench head 4 is fixedly installed on the left surface of the annular frame 3; An auxiliary mechanism is provided on the valve wrench 1. The auxiliary mechanism includes a handle 5 and a tightening bolt 6. Two first connecting plates 7 are fixedly connected to the lower end of the valve wrench 1. A second connecting plate 8 is rotatably installed on the inner wall of the two first connecting plates 7. The handle 5 is fixedly connected to the lower end of the second connecting plate 8. The tightening bolt 6 is threaded on the right surface of the annular frame 3. The thread of the left end of the tightening bolt 6 penetrates into the interior of the annular frame 3 and contacts the valve wrench 1. A mounting plate 9 is fixedly installed on the lower end of the left surface of the valve wrench 1. A rectangular groove 10 is opened on the lower surface of the mounting plate 9. A limit plate 11 is slidably inserted into the interior of the rectangular groove 10.

[0016] Furthermore, the auxiliary mechanism also includes a sleeve 12, which is fitted onto the outer surface of the throttle 5.

[0017] Furthermore, by allowing the annular frame 3 to slide along the valve wrench 1 and being fixed in place with the tightening bolt 6, the wrench head 4 can adapt to valve handwheels of different specifications and positions. The rotatable handle 5 can adjust the length of the valve wrench main rod. When rotating normally, it can be turned to the vertical direction for easy and rapid rotation, which improves the efficiency of valve opening and closing. The cooperation between the threaded rod 13 and the rotating rod 15 drives the limiting plate 11 to restrict and fix the rotation of the handle 5, preventing the handle 5 from rotating arbitrarily when the operator picks up the wrench, avoiding inconvenience or safety hazards caused by the handle shaking, and improving the stability and safety of use.

[0018] Furthermore, a threaded rod 13 is rotatably mounted on the upper inner wall of the rectangular groove 10. The threaded rod 13 is threadedly connected to the limiting plate 11, and a circular hole 14 is opened on the upper surface of the mounting plate 9.

[0019] Furthermore, a rotating rod 15 is rotatably mounted inside the circular hole 14, and the lower end of the rotating rod 15 is fixedly connected to the threaded rod 13.

[0020] Furthermore, an annular groove 16 is provided on the inner wall of the circular hole 14, and an annular plate 17 is rotatably installed inside the annular groove 16. The annular plate 17 is fixedly connected to the rotating rod 15.

[0021] Furthermore, a handle 2 is fixedly installed on the right surface of the valve wrench 1.

[0022] Furthermore, when using this valve wrench, the annular frame 3 can be slid along the outer surface of the valve wrench 1, aligning the wrench head 4 with the valve handwheel to be operated. By rotating the tightening bolt 6, its left end is pressed against the valve wrench 1, fixing the position of the annular frame 3 and ensuring that the wrench head 4 stably holds the handwheel. If the valve is installed in a narrow space, the position of the annular frame 3 can be adjusted first so that the wrench head 4 can smoothly engage the handwheel, then the tightening bolt 6 is fixed, and the handle 5 is rotated so that it is perpendicular to the valve wrench 1, reducing the valve wrench opening. With the length of 1, hold the handle 2 and the socket 12 on the throttle 5, apply force evenly, and drive the handwheel to rotate through the wrench head 4 to open the valve. When it is necessary to fix the position of the throttle 5 to prevent the throttle 5 from rotating arbitrarily, the rotating rod 15 can be rotated to drive the threaded rod 13 to rotate, so that the limiting plate 11 slides up and down in the rectangular groove 10. When the limiting plate 11 moves downward and gets into the rotation path of the throttle 5, the rotation of the throttle 5 can be restricted and kept in the desired position; conversely, moving the limiting plate 11 upward can release the restriction.
