Description

Technical Field

[0001] This application relates to the field of industrial technologies, specifically a wrench for a valve body tooling. Background Art

[0002] The wrench used for valve body tooling, usually called a valve disassembly wrench or a valve wrench, is a special tool specifically for opening, closing, repairing, and maintaining valves.

[0003] After the existing valve body and the bottle body are welded, it is now necessary to disassemble the valve body tooling. Generally, a bayonet wrench is used for disassembly. Since the bayonet of the wrench is U-shaped, during the process of assembling and disassembling the valve body tooling with the wrench, the bayonet is easily opened to both sides under the influence of the valve body tooling, resulting in slippage between the bayonet and the valve body tooling, causing damage to the wrench and affecting disassembly. At the same time, when there is slippage between the wrench and the valve body tooling, when the wrench hits the valve body bottle, it is easy to scrape and damage the bottle body.

[0004] Therefore, this application provides a wrench for a valve body tooling to solve the above problems. Utility Model Content

[0005] This application provides a wrench for a valve body tooling, aiming to solve the problems in the background art that the bayonet of the existing wrench is U-shaped, and during the process of assembling and disassembling the valve body tooling with the wrench, the bayonet is easily opened to both sides under the influence of the valve body tooling, resulting in slippage between the bayonet and the valve body tooling, causing damage to the wrench and affecting disassembly. At the same time, when there is slippage between the wrench and the valve body tooling, when the wrench hits the valve body bottle, it is easy to scrape and damage the bottle body, etc.

[0006] To achieve the above object, this application provides the following technical solution: A wrench for a valve body tooling includes a base, a bayonet opened at one end of the base for clamping outside the valve body tooling, a socket opened on the base and communicating with the bayonet, and a handle fixedly provided at one end of the base away from the bayonet. When in use, first hold the handle, then clamp the bayonet at the end of the base away from the handle on the valve body tooling, and then drive the base to rotate through the handle to achieve the installation or disassembly of the valve body tooling.

[0007] To improve the clamping stability of the bayonet: A limiting block for limiting the diameter of the bayonet is fixedly provided in the bayonet. When disassembling the valve body tooling, the limiting block can limit the diameter of the stressed part of the bayonet to prevent the diameter of the bayonet from deforming under force, avoid slippage between the bayonet and the valve body tooling, and achieve the clamping stability of the base on the valve body tooling.

[0008] To prevent the wrench from scraping and damaging the valve body bottle when the wrench slips on the valve body tooling: buffer pads are symmetrically and fixedly arranged on one side of the base corresponding to the socket. When the wrench slips on the valve body tooling, the buffer pads collide with the valve body bottle, preventing the wrench from contacting the bottle body and protecting the bottle body.

[0009] Preferably, for the convenience of installing, disassembling and replacing the buffer pads: screws are inserted through through-holes on the buffer pads, and threaded holes for the screws to be threadedly inserted are provided on the base. The use of screws facilitates the installation of the buffer pads. When the buffer pads are worn, only the screws need to be unscrewed to replace the buffer pads.

[0010] Preferably, to improve the elasticity and wear resistance of the buffer pads: the buffer pads are made of resin material. Resin has high strength, high wear resistance, chemical corrosion resistance and good processing performance.

[0011] Preferably, for the convenience of storing the handle when it is idle: a through-groove for hanging the handle is provided at one end of the handle away from the base. When the handle is not in use, the handle can be conveniently hung at a designated position through the cooperation of the convex pin and the through-groove.

[0012] Preferably, to avoid discomfort to the hand caused by the handle: a protective sleeve is fixedly sleeved on the handle. During the process of holding the handle, the hand contacts the protective sleeve, improving the comfort between the hand and the handle.

[0013] Preferably, the protective sleeve is made of silicone material. Silicone has the characteristics of high temperature resistance, easy cleaning, bright color, good feel, long service life, non-toxic and odorless, stable chemical properties, strong adsorption, etc.

[0014] Preferably, both the base and the handle are made of chrome vanadium steel material.

[0015] Preferably, to avoid rust on the surfaces of the base and the handle: a layer of bright chromium is electroplated on both the base and the handle. After the base and the handle are polished and buffed, through electrolysis, a uniform and dense chromium layer is deposited on the surface of the chrome vanadium steel, forming a surface with a bright chromium effect. This can not only further improve its appearance aesthetics but also enhance its rust prevention, corrosion resistance and other properties, thereby extending the service life of the tool.

[0016] When disassembling the valve body tooling in this application, the limiting block can limit the caliber of the stressed bayonet part to prevent the bayonet caliber from deforming under force, avoid slipping between the bayonet and the valve body tooling, and realize the clamping stability of the base for the valve body tooling.

[0017] When the wrench and the valve body tooling slip, the buffer pad impacts the valve body bottle, preventing the wrench from contacting the bottle and protecting the bottle. The buffer pad is made of resin material. Resin has high strength, high wear resistance, chemical corrosion resistance, and good processing performance.

[0018] In this application, a protective sleeve made of silicone is sleeved outside the handle to improve the comfort between the hand and the handle. Brief Description of the Drawings

[0024] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0025] Embodiment 1

[0026] This embodiment provides a wrench for removing the valve body tooling. As Figures 1-3 shown, the wrench includes a base 1, a bayonet 11 opened at one end of the base 1 for clamping outside the valve body tooling, a socket 12 opened on the base 1 and communicating with the bayonet 11, and a handle 2 fixedly provided at one end of the base 1 away from the bayonet 11. When in use, first hold the handle 2, then clamp the bayonet 11 at one end of the base 1 away from the handle 2 on the valve body tooling, and then drive the base 1 to rotate through the handle 2 to install or remove the valve body tooling.

[0027] To improve the clamping stability of the bayonet 11: A limit block 3 for limiting the caliber of the bayonet 11 is fixedly arranged inside the bayonet 11. During use, first place the limit block 3 inside the bayonet 11, and then fix and weld the limit block 3 to the base 1 by welding. When the base 1 rotates the valve body tooling through the bayonet 11, the limit block 3 can limit the caliber of the stressed part of the bayonet 11 to prevent the deformation of the bayonet 11 caliber due to force, avoid slipping between the bayonet 11 and the valve body tooling, and achieve the clamping stability of the base 1 to the valve body tooling.

[0028] To prevent the wrench from scraping and damaging the valve body bottle when the wrench slips with the valve body tooling: On one side of the base 1 corresponding to the socket 12, buffer pads 4 are symmetrically and fixedly arranged. During use, first install the two buffer pads 4 symmetrically on the base 1. When the wrench slips with the valve body tooling, the buffer pads 4 collide with the valve body bottle, avoiding contact between the wrench and the bottle body, and achieving the protection of the bottle body.

[0029] Specifically, to facilitate the installation, disassembly and replacement of the buffer pad 4: A screw 42 is inserted through a through hole 41 on the buffer pad 4, and a threaded hole 13 for threaded insertion of the screw 42 is opened on the base 1. During use, the screw 42 passes through the through hole 41 of the through slot 21 and is threadedly inserted into the threaded hole 13. The installation of the screw 42 facilitates the installation of the buffer pad 4. When the buffer pad 4 is worn, only need to unscrew the screw 42 to replace the buffer pad 4.

[0030] More specifically, to improve the elasticity and wear resistance of the buffer pad 4: The buffer pad 4 is made of resin material. Resin has high strength, high wear resistance, chemical corrosion resistance and good processing performance.

[0031] Further, to facilitate the storage of the handle 2 when it is idle: A through slot 21 for hanging the handle 2 is opened at one end of the handle 2 away from the base 1. When the handle 2 is not in use, it is convenient to hang the handle 2 at a designated position through the cooperation of the through slot 21 and the protruding nail.

[0032] Specifically, both the base 1 and the handle 2 are made of chrome vanadium steel material.

[0033] More specifically, to avoid rust stains on the surfaces of the base 1 and the handle 2: A layer of bright chromium is electroplated on both the base 1 and the handle 2. After the base 1 and the handle 2 are polished and buffed. Through electrolysis, a uniform and dense chromium layer is deposited on the surface of the chrome vanadium steel, forming a surface with a bright chromium effect, which can not only further improve its appearance aesthetics, but also enhance its anti-rust, corrosion resistance and other properties, thereby extending the service life of the tool.

[0034] Embodiment 2

[0035] Different from Embodiment 1, (when holding the handle 2, there will be a problem that the hardness of the handle is too high and it will leave marks on the hand). Therefore, a protective sleeve 22 is fixedly sleeved on the handle 2. During use, first, the protective sleeve 22 is sleeved on the handle 2. During the process of holding the handle 2, the hand contacts with the protective sleeve 22, improving the comfort between the hand and the handle 2.

[0036] Furthermore, the protective sleeve 22 is made of silicone material. Silicone has the characteristics of high temperature resistance, easy cleaning, bright color, good hand feeling, long service life, non-toxic and odorless, stable chemical properties, strong adsorption, etc.

[0037] As mentioned above, the above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and its concept of the present application, making equivalent substitutions or changes should be covered within the protection scope of the present application.
