Description

Technical Field

[0001] This utility model relates to a valve switching tool, specifically an auxiliary C-type wrench for valve switching. Background Technology

[0002] Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow splitting, and pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to the various valves used in highly complex automated control systems, exhibiting a wide variety of types and specifications. Valve operation is also an essential step in valve testing.

[0003] During valve testing, it is extremely difficult to open or close the valve manually or with traditional pipe wrenches. When the valve is clamped onto the testing equipment and the valve is opened or closed, the wrench and handwheel may slip relative to each other during the turning of the handwheel. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary C-type wrench for valve switching, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An auxiliary C-type wrench for valve switching includes a wrench body, the wrench body having a gripping part and a locking part;

[0007] The engaging part includes a first C-shaped engaging member and a second C-shaped engaging member. The openings of the first C-shaped engaging member and the second C-shaped engaging member are perpendicular to each other. The opening of the first C-shaped engaging member is engaged above or below the valve handwheel, and the second C-shaped engaging member is engaged along the outer ring of the valve handwheel and abuts against the valve handwheel.

[0008] The auxiliary C-type wrench for valve switching as described above: the arc of the first C-type engaging member is greater than 180°.

[0009] The auxiliary C-type wrench for valve switching as described above: the arc of the second C-type engagement member is less than or equal to 180°.

[0010] As described above, the auxiliary C-type wrench for valve switching: the first C-type engaging member and the second C-type engaging member are respectively fixed at both ends of the arc-shaped connecting member connected to the gripping part.

[0011] As described above, the auxiliary C-type wrench for valve switching has an arc greater than 180°, so that the radial planes of the first C-type engaging member and the second C-type engaging member intersect.

[0012] As described above, the auxiliary C-type wrench for valve switching has an arc of 180°, so that the radial planes of the first C-type engaging member and the second C-type engaging member are parallel to each other.

[0013] The auxiliary C-type wrench for valve switching as described above: a main lever is fixed on the arc-shaped connector, and the main lever forms the gripping part.

[0014] The auxiliary C-type wrench for valve switching as described above: the main lever is equipped with a non-slip handle.

[0015] The auxiliary C-type wrench for valve switching as described above: the anti-slip handle is a rubber sleeve fitted on the main lever or an anti-slip texture formed on the main lever.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] When the first and second C-type locking parts are engaged on the valve handwheel, they abut against the inner and outer sides of the handwheel, forming two support points with opposite force directions. When the grip rotates, it can drive the valve handwheel to rotate, thereby achieving the function of quickly opening and closing the valve. Combined with the length of the grip, it forms a lever, which saves effort. Furthermore, through the cooperation of the first and second C-type locking parts, stable engagement of valve handwheels of different sizes can be achieved, improving the wrench's versatility and practicality. In addition, since the openings of the first and second C-type locking parts are perpendicular to each other, the engagement process is simpler, allowing for quick and accurate engagement of the valve handwheel, further improving work efficiency.

[0018] When the operator applies force, the end of the first C-shaped locking part extends below or above the contact position with the valve handwheel, which can effectively increase the contact area with the valve handwheel, thereby improving the stability of the locking. At the same time, when the wrench body rotates the valve handwheel, it is not easy to slip off, further ensuring the safety and reliability of operation. Attached Figure Description

[0025] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0026] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0027] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail, in order to highlight the main points of this application.

[0028] Please see Figures 1-4 In this embodiment of the present invention, an auxiliary C-type wrench for valve switching includes a wrench body, the wrench body having a gripping part and a locking part; the locking part includes a first C-type locking member 4 and a second C-type locking member 5, the openings of the first C-type locking member 4 and the second C-type locking member 5 being perpendicular to each other, the opening of the first C-type locking member 4 being engaged above or below the valve handwheel, and the second C-type locking member 5 being engaged along the outer ring of the valve handwheel and abutting against the valve handwheel, preferably, the opening of the first C-type locking member 4 being perpendicular to the length direction of the gripping part.

[0029] When the first C-type locking component 4 and the second C-type locking component 5 are engaged on the valve handwheel, they abut against the inner and outer sides of the valve handwheel, forming two support points with opposite force directions. When the grip rotates, it can drive the valve handwheel to rotate, thereby achieving the function of quickly opening and closing the valve. Combined with the length of the grip, a lever is formed, which saves effort. Furthermore, through the cooperation of the first C-type locking component 4 and the second C-type locking component 5, stable engagement of valve handwheels of different sizes can be achieved, improving the versatility and practicality of the wrench. In addition, since the openings of the first C-type locking component 4 and the second C-type locking component 5 are perpendicular to each other, the engagement process is simpler, and the valve handwheel can be engaged quickly and accurately, further improving work efficiency.

[0030] Furthermore, the arc of the first C-shaped engaging member 4 is greater than 180°. When the operator applies force, the end of the first C-shaped engaging member 4 extends to the area below or above the contact position with the valve handwheel, which can effectively increase the contact area with the valve handwheel, thereby improving the stability of the engagement. At the same time, when the wrench body rotates the valve handwheel, it is not easy to slip off, further ensuring the safety and reliability of the operation.

[0031] Furthermore, the curvature of the second C-type engaging component 5 is less than or equal to 180°, which reduces the curvature of the second C-type engaging component 5 to a certain extent, making the second C-type engaging component 5 more flexible when engaging, and able to adapt to valve handwheels of different sizes and shapes, thereby enhancing the adaptability and flexibility of the wrench.

[0032] The first C-shaped engaging member 4 and the second C-shaped engaging member 5 are respectively fixed to both ends of the arc-shaped connecting member 3 connected to the gripping part, so that there is a certain distance between the first C-shaped engaging member 4 and the second C-shaped engaging member 5. This increases the distance between the first C-shaped engaging member 4 and the second C-shaped engaging member 5 when they abut against the valve handwheel, thereby generating greater torque when the valve handwheel is turned, making the turning easier and less strenuous. In addition, this design also helps to clamp the valve handwheel from different angles when engaging valve handwheels of different sizes, improving the stability of the engagement and the convenience of operation.

[0033] As an example, one implementation method is described in [reference needed]. Figure 4 The arc of the arc-shaped connector 3 is equal to 180°, so that the radial planes of the first C-shaped snap-fit ​​4 and the second C-shaped snap-fit ​​5 are parallel to each other.

[0034] As an example, one implementation method is described in [reference needed]. Figure 5 The arc of the arc-shaped connector 3 is greater than 180°, so that the radial planes of the first C-type engaging member 4 and the second C-type engaging member 5 intersect, which increases the contact area between the first C-type engaging member 4 and the second C-type engaging member 5 and the valve handwheel. It also makes the wrench adaptable to more types of valve handwheels, improving the wrench's versatility and practicality. In addition, it helps to distribute the applied force more evenly between the two engaging members when rotating the valve handwheel, avoiding loosening of the engagement or damage to the valve handwheel due to uneven force.

[0035] Furthermore, a main lever 1 is fixed on the arc-shaped connector 3, and the main lever 1 forms the gripping part. Both the main lever 1 and the arc-shaped connector 3 are made of metal, and the main lever 1 and the arc-shaped connector 3 are welded together, which can improve the stability of the connection between the main lever 1 and the arc-shaped connector 3.

[0036] Preferably, the main lever 1 is provided with an anti-slip handle 2, wherein the anti-slip handle 2 is a rubber sleeve fitted on the main lever 1 or an anti-slip texture formed on the main lever 1, so as to provide better grip stability and comfort, prevent accidental injury caused by hand slippage when using a wrench to turn the valve handwheel, and at the same time, it can also effectively prevent discomfort caused by friction in the hand after long-term use.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
