Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of valve adjustment auxiliary equipment, specifically an adjustable valve wrench. Background Technology
[0002] Pipeline valves are crucial basic components in industrial production and civil facilities. In fluid (liquid, gas, slurry, etc.) transportation systems, pipeline valves are devices used to control the direction, pressure, and flow rate of the fluid. Valves enable various functions such as opening, closing, regulating, guiding, preventing backflow, stabilizing, and relieving pressure in pipelines. In industrial production processes, complex pipeline systems often have numerous and densely packed valves. For operators, manually adjusting valves is not only inefficient but also extremely inconvenient in situations with limited space. A utility model patent (CN201820045261.9) proposes a valve wrench, but its pawls for contacting the valve are in a fixed position, resulting in poor adaptability to different types and sizes of valves. Furthermore, turning the valve relies solely on the handle, making it inconvenient to turn when the operator is in a radial position. Therefore, we propose an adjustable valve wrench to solve these problems. Utility Model Content
[0003] To address the above technical problems, this utility model provides an adjustable valve wrench.
[0004] To solve the above-mentioned technical problems, the present invention provides an adjustable valve wrench, comprising a body, the lower part of which is bent forward, and the upper part of which has several adjustment through holes. A pawl passes through the adjustment through holes, and a first positioning nut and a second positioning nut are threaded onto the pawl. The first positioning nut and the second positioning nut are respectively located on both sides of the body, and a handle is connected to the lower part of the body.
[0005] Furthermore, the lower part of the body is rotatably connected to the handle.
[0006] Furthermore, the lower part of the main body is fixedly connected to the handle.
[0007] Furthermore, a sleeve is fitted onto the handle, and a limit block is fixedly connected to the front end of the handle.
[0008] Furthermore, a locking block is fixedly connected to the rear end of the claw.
[0009] Furthermore, gaskets are provided between the first positioning nut and the body, and between the second positioning nut and the body.
[0010] This utility model has the following advantages compared with the prior art:
[0011] This utility model allows for adjustment of the position of the pawl on the adjustment through hole by tightening the positioning nut, making it adaptable to different types and sizes of valve turntables and enhancing its practicality. The radial handle makes it easier for operators to rotate the valve turntable, greatly improving the stability and reliability of force application. The locking block prevents slippage when rotating the valve, thereby improving the efficiency and safety of valve regulation. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings.
[0016] like Figures 1 to 2 An adjustable valve wrench is shown, comprising a body 1. The lower part of the body 1 is bent forward to prevent the lower part of the body 1 from exceeding the valve radius when rotated, thus avoiding movement interference with other valves nearby. The upper part of the body 1 has three strip-shaped adjustment through holes 2, and a pawl 3 is vertically inserted through the adjustment through holes 2. A first positioning nut 4 and a second positioning nut 5 are threaded onto the pawl 3. The first positioning nut 4 and the second positioning nut 5 are located on both sides of the body 1. A handle 7 is connected to the lower part of the body 1 to facilitate the operator to rotate the wrench.
[0017] The lower part of the body 1 and the handle 7 can be rotatably connected or fixedly connected. When the handle 7 is rotatably connected to the body 1, it can be achieved through a bearing. The outer edge of the bearing is fixedly connected to the body 1, and the handle 7 is fixedly connected to the inner ring of the bearing. When the handle 7 and the body 1 are fixedly connected, a sleeve 8 can be fitted on the handle 7. This makes it easier for the operator to turn the wrench. The sleeve 8 replaces the rotatable connection of the handle 7 to achieve a more convenient turning effect. A limit block 9 is fixedly connected to the front end of the handle 7 to prevent the sleeve 8 from slipping out of the handle 7 during the rotation.
[0018] To prevent the chuck 3 from sliding off the valve turntable during rotation, a locking block 6 is fixedly connected to the rear end of the chuck 3, which improves the efficiency and safety of the regulating valve.
[0019] Washers are provided between the first locating nut 4 and the body 1, and between the second locating nut 5 and the body 1. The friction generated between the washers and the body 1 enhances the connection stability and prevents the nuts from loosening during wrench rotation. At the same time, the washers also increase the contact area between the nuts and the body 1, reducing local pressure and preventing local deformation of the body 1.
[0020] The working process of this embodiment is as follows:
[0021] First, adjust the position of the locking jaws according to the type and size of the valve. During adjustment, loosen the first positioning nut 4 in sequence so that the three locking jaws 3 can extend into the gap of the connecting rod on the valve disc. Tighten the three first positioning nuts 4 so that the first positioning nuts 4 and the second positioning nuts 5 are tightly against the body 1, securing the three locking jaws 3. Then, the operator can hold the handle 7 and begin rotating the valve disc. After the valve adjustment is complete, remove the wrench.
