Description

Technical Field

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

[0002] In fluid pipeline systems, valves are control elements whose main functions are to isolate equipment and pipeline systems, regulate flow, prevent backflow, regulate and release pressure. They can be used to control the flow of various types of fluids, such as air, water, steam, various corrosive media, mud, oil, liquid metals and radioactive media. In daily life, common manual valves include a valve body 101, a screw or threaded rod rotatably connected to the valve body 101, a nut 102 screwed onto the screw or threaded rod, and a handwheel screwed onto the screw or threaded rod. The handwheel includes an outer ring 1031 coaxially arranged, an inner ring 1032 screwed onto the screw or threaded rod, and multiple connecting rods 1033 for connecting the outer ring 1031 and the inner ring 1032. The multiple connecting rods 1033 divide the area between the outer ring 1031 and the inner ring 1032 into multiple sector-shaped areas. For example, in a manual valve for a small sluice gate disclosed in CN114321417A and a manual valve disclosed in CN202302074U, the tool usually used to turn the valve handwheel is a valve wrench.

[0003] However, when the valve is installed in a difficult position, the operator is far away from the handwheel and it is difficult to apply force directly to the handwheel, which increases the difficulty of the operator's work. Utility Model Content

[0004] The purpose of this utility model is to address the above-mentioned shortcomings by providing a multi-angle combination valve wrench. When the valve is installed in a difficult position, the valve can be operated without direct contact with the handwheel, thus reducing the difficulty of the operator's work.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-angle combination valve wrench includes a wrench base, multiple wrench pins disposed at one end of the wrench base, and a handle connected to the wrench base at one end. The wrench base is provided with a hexagonal through hole penetrating the wrench base. One end of each wrench pin is fixed to the wrench base, and the multiple wrench pins are arranged around the hexagonal through hole.

[0007] Furthermore, at least three levers are provided, and the three levers are arranged at equal angles with the axis of the hexagonal through hole as the center.

[0008] Furthermore, the handle includes a support rod with a fixed wrench seat welded to its bottom end, and the top ends of the three support rods are welded to the same connecting seat. A hand handle is fixed on the connecting seat, and a wheel is provided at the top end of the hand handle.

[0009] Furthermore, the handheld rod includes an outer tube with its bottom end fixed to a connecting seat, an inner tube with its bottom end slidably connected inside the outer tube, a rotating wheel fixedly connected to the top end of the inner tube after it extends out of the outer tube, and multiple external threaded holes are provided on the outer tube along the length direction of the outer tube, and an internal threaded hole is provided on the inner tube opposite to the outer tube, and the external threaded hole and the internal threaded hole are connected by bolts.

[0010] Furthermore, the wrench base is an equilateral triangular base, with the three wrench posts respectively positioned near the three corners of the base, and the support rod corresponding to each wrench post.

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

[0012] In practical applications, the wrench is inserted between adjacent valve connecting rods, with the hexagonal through hole aligned with the valve nut. Turning the handle drives the wrench seat, which in turn rotates the valve nut through the hexagonal through hole. Simultaneously, the wrench pushes the valve connecting rod to rotate the handwheel, thus completing the valve operation. This invention allows valve operation without direct contact with the handwheel when the valve is installed in a difficult location, reducing the difficulty of the operator's work.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a multi-angle combination valve wrench includes a wrench base 1, multiple wrench pins 2 disposed at one end of the wrench base 1, and a handle 3 connected to the wrench base 1 at one end. The wrench base 1 is provided with a hexagonal through hole 11 penetrating the wrench base 1. One end of each wrench pin 2 is fixed to the wrench base 1, and the multiple wrench pins 2 are arranged around the hexagonal through hole 11.

[0020] In use, insert the wrench 2 between adjacent valve connecting rods 1033, with the hexagonal through hole 11 aligned with the valve nut 102. Rotate the handle 3, which in turn drives the wrench seat 1. The wrench seat 1, through the hexagonal through hole 11, drives the valve nut 102 to rotate. Simultaneously, the wrench 2 pushes the valve connecting rod 1033 to rotate the handwheel, thus completing the valve operation. This invention allows the valve to be operated without direct contact with the handwheel when the valve is installed in a difficult position, reducing the difficulty of operation for the operator.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, at least three levers 2 are provided, and the three levers 2 are arranged at equal angles with the axis of the hexagonal through hole 11 as the center. In this embodiment, the valve connecting rod 1033 is subjected to force by the three levers 2 arranged at equal angles with the axis of the hexagonal through hole 11 as the center, so that the valve handwheel is subjected to more uniform force.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the handle 3 includes a support rod 31 with a fixed wrench seat 1 welded to its bottom end. The top ends of the three support rods 31 are welded to the same connecting seat 32. A hand handle 33 is fixed on the connecting seat 32. A rotating wheel 34 is provided at the top end of the hand handle 33. In this embodiment, when in use, the wrench 2 is inserted between adjacent valve connecting rods 1033, with the hexagonal through hole 11 aligned with the valve nut 102. The rotating wheel 34 is rotated, and the rotating wheel 34 drives the wrench seat 1 through the hand handle 33, the connecting seat 32, and the support rod 31. The wrench seat 1 drives the valve nut 102 to rotate through the hexagonal through hole 11. At the same time, the wrench 2 pushes the valve connecting rod 1033 to rotate the handwheel, thus completing the operation of the valve.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the handheld lever 33 includes an outer tube 331 with its bottom end fixed to a connecting seat 32, and an inner tube 332 slidably connected to the bottom end of the outer tube 331. The top end of the inner tube 332 extends out of the outer tube 331 and is fixedly connected to a rotating wheel 34. Along the length of the outer tube 331, the outer tube 331 is provided with a plurality of external connecting threaded holes 3311, and the inner tube 332 is provided with an internal connecting threaded hole 3321 opposite to the outer tube 331. The external connecting threaded holes 3311 and the internal connecting threaded holes 3321 are connected by bolts. In this embodiment, by adjusting the opposite external connecting threaded holes 3311 and internal connecting threaded holes 3321, the length of the handheld lever 33 is adjustable, making it more versatile.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the wrench base 1 is an equilateral triangular base, and the three wrench posts 2 are respectively set near the three corners of the base. The support rods 31 correspond one-to-one with the wrench posts 2. In this embodiment, by having the three support rods 31 correspond one-to-one with the wrench posts 2, the force applied to the handle is more even.

[0025] The specific embodiments described herein are merely illustrative examples of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the scope defined by this utility model.
