[0026] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0027] In the present disclosure, unless otherwise indicated, the directional words used, such as "inside" and "outside", refer to the inside and outside relative to the contour of the corresponding component itself. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0028] According to a specific embodiment of the present disclosure, a ratchet valve wrench is provided, referring to Figure 1 and Figure 2 As shown, the ratchet valve wrench may include a ratchet seat 1, a ratchet 2, a handle 3 and a clamping claw seat 4. The ratchet seat 1 may be provided with a mounting through hole 10, and the ratchet 2 may be rotatably accommodated in the mounting through hole 10. The ratchet seat 1 may also be provided with a ratchet pawl (not shown) for cooperating with the ratchet 2, so that the ratchet 2 can rotate unidirectionally in the mounting through hole 10, that is, when the ratchet 2 is configured to rotate clockwise relative to the mounting through hole 10, if the ratchet 2 rotates counterclockwise, the ratchet 2 will drive the ratchet seat 1 to rotate counterclockwise together, and when the ratchet 2 is configured to rotate counterclockwise relative to the mounting through hole 10, if the ratchet 2 rotates clockwise, the ratchet 2 will drive the ratchet seat 1 to rotate clockwise together.

[0029] The handle 3 can be fixedly connected to one of the ratchet seat 1 and the ratchet 2, and the jaw seat 4 can be fixedly connected to the end surface of the other of the ratchet seat 1 and the ratchet 2. The side surface of the jaw seat 4 facing away from the ratchet seat 1 is provided with a plurality of outwardly protruding jaws 40 to be inserted between the spokes (not shown) of the valve handwheel. The plurality of jaws 40 can be arranged at intervals around the central axis of the ratchet 2 so as to cooperate with the spokes of the valve handwheel.

[0030] Different types of valve handwheels have different numbers of spokes, which results in different distances between spokes on different types of valve handwheels. A portion of the plurality of jaws 40 may be configured as fixed jaws 41 fixedly connected to the jaw seat 4, and another portion may be configured as movable jaws 42 slidably connected to the jaw seat 4, so that the distance between the movable jaws 42 and adjacent jaws 40 is adjustable, thereby enabling the distance between adjacent jaws 40 to match the distance between the spokes on the valve handwheel.

[0031] Through the above technical solution, in the ratchet valve wrench provided by the present disclosure, the distance between the movable jaw 42 and the adjacent jaw 40 can be adjusted by relative sliding between the movable jaw 42 and the jaw seat 4, so that the jaw seat 4 can cooperate with the valve handwheel with different numbers of spokes, and the two are relatively fixed along the rotation direction of the valve wrench, thereby avoiding the valve wrench and the valve handwheel from slipping. In this way, the versatility of the ratchet valve wrench can be improved, and the connection reliability between the ratchet valve wrench and the valve handwheel can be improved, thereby improving the opening and closing efficiency of the valve.

[0032] As a specific embodiment of the present disclosure, refer to Figure 1 and Figure 2As shown, the handle 3 can be fixedly connected to the ratchet seat 1, and the clamping claw seat 4 can be fixedly connected to one end surface of the ratchet 2. When the ratchet 2 is set to be able to rotate clockwise relative to the installation through hole 10, that is, the ratchet seat 1 can rotate counterclockwise relative to the ratchet 2, the staff can drive the ratchet seat 1, the ratchet 2 and the clamping claw seat 4 to rotate clockwise through the handle 3, thereby driving the valve handwheel to rotate clockwise through the clamping claw seat 4; when the ratchet 2 is set to be able to rotate counterclockwise relative to the installation through hole 10, that is, the ratchet seat 1 can rotate clockwise relative to the ratchet 2, the staff can drive the ratchet 1, the ratchet 2 and the clamping claw seat 4 to rotate counterclockwise through the handle 3, thereby driving the valve handwheel to rotate counterclockwise through the clamping claw seat 4. Through the above process, the valve can be opened or closed.

[0033] In order to switch the direction of relative rotation between the ratchet 2 and the ratchet seat 1, refer to Figure 1 As shown, a reversing paddle 5 may be provided on the ratchet seat 1, and by adjusting the position of the reversing paddle 5, the ratchet 2 can be rotated clockwise relative to the mounting through hole 10 or the ratchet 2 can be rotated counterclockwise relative to the mounting through hole 10. Specifically, the matching mode between the ratchet 2, the pawl in the ratchet seat 1, and the reversing paddle 5 on the ratchet seat 1 in the specific embodiment of the present disclosure can adopt the matching mode between the ratchet teeth 51, the pawl body 81, and the elastic member 82 in the patent with publication number CN219504636U.

[0034] As another specific embodiment of the present disclosure that is not shown, the handle 3 can be fixedly connected to the ratchet 2 , and the clamping claw seat 4 can be fixedly connected to the ratchet seat 1 .

[0035] refer to Figure 2 As shown, a side surface of the clamping jaw seat 4 facing away from the handle may be provided with a slide groove 43 , and the movable clamping jaw 42 may be slidably connected to the slide groove 43 .

[0036] In order to limit the position of the movable jaw 42 in the slide slot 43, an elastic member (not shown) may be connected between the movable jaw 42 and the jaw seat 4, and the elastic member may provide the movable jaw 42 with an elastic force to move toward one end of the slide slot 43, so that the movable jaw 42 is retained at one end of the slide slot 43. In actual use, when the distance between adjacent jaws 40 needs to be adjusted, the elastic force of the elastic member may be overcome to move the movable jaw 42 until the movable jaw 42 is moved to a position suitable for cooperating with the spoke, so that the movable jaw 42 can be pressed against the spoke under the elastic force of the elastic member, so that the jaw seat 4 and the valve handwheel are relatively fixed along the rotation direction of the valve wrench.

[0037] In addition, reference Figure 2As shown, at least one fixed jaw 41 is provided between two adjacent movable jaws 42, so that the distance between each movable jaw 42 and the adjacent jaw 40 is adjustable only in one direction to avoid relative rotation between the jaw seat 4 and the valve handwheel, thereby further improving the connection reliability between the jaw seat 4 and the valve handwheel.

[0038] refer to Figure 1 As shown, one end of the ratchet 2 can extend out of the mounting through hole 10 and can be provided with a stop flange 21 extending radially outward of the ratchet 2. The stop flange 21 stops on the surface of the ratchet seat 1 to prevent axial movement between the ratchet 2 and the ratchet seat 1.

[0039] In order to facilitate the insertion of the clamping jaws 40 between the spokes of the valve hand wheel, refer to Figure 2 As shown, the clamping jaw 40 may be configured as a columnar structure.

[0040] In order to avoid slipping between the jaws 40 and the spokes of the valve handwheel, refer to Figure 2 As shown, a groove 401 for cooperating with the spoke of the valve handwheel can be provided on the outer circumference of the clamp 40, and the outer circumference of the spoke can cooperate with the inner wall of the groove 401, thereby increasing the contact area between the clamp 40 and the spoke and improving the cooperation stability between the clamp 40 and the spoke.

[0041] In order to facilitate the staff to operate the valve wrench, refer to Figure 1 and Figure 2 As shown, the end of the handle 3 away from the ratchet seat 1 and the ratchet 2 may be provided with an anti-slip gripping portion 31 to improve the comfort of use of the valve wrench. The anti-slip gripping portion 31 may be configured as an anti-slip coating applied on the handle 3, for example, polyurethane coating, epoxy coating, anti-slip paint, etc. may be applied on the handle 3; or the anti-slip gripping portion 31 may be formed by engraving a groove on the handle 3 or sandblasting.

[0042] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
