Description

Technical Field

[0001] The utility model relates to the technical field of wrenches, in particular to a valve wrench. Background Art

[0002] Conventional steam pipelines are all provided with valves for controlling the flow of steam. A handwheel is arranged on the valve, and the staff controls the opening and closing state of the valve by rotating the handwheel. Since the steam valve forms a part of the steam pipeline, the long-term flow of high-temperature steam will transfer part of the heat to the handwheel of the valve. In this way, when the staff rotates the handwheel, it is easy to cause burns, which has certain potential safety hazards.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] AsFigure 1-6 A valve wrench as shown includes a main rod 1. A fixed clamping rod 11 is provided at the end of the main rod 1, and an adjusting clamping rod 12 is parallel to the fixed clamping rod 11 and is limitedly movable on the main rod 1. Since the valve handwheel of the steam pipeline is subjected to heat transfer for a long time, its own temperature is too high. When a staff member turns it by hand, it may cause burns. Therefore, this wrench can be used to assist in turning the handwheel. When using the wrench, the fixed clamping rod 11 at the front end abuts against one side of the spoke of the handwheel, and then the adjusting clamping rod 12 abuts against the other side of the spoke relatively and misaligned to clamp the handwheel. Then, by pulling the wrench to drive the handwheel to rotate, the adjustment of the valve can be realized, avoiding the risk of burns. At the same time, this wrench can also be applied to all valves with handwheels. The structure of its force arm makes the adjustment work of the valve easier and more stable.

[0024] In an embodiment, a limiting ring 2 is provided on the main rod 1. A sliding ring 21 is slidably sleeved on the main rod 1 between the limiting ring 2 and the fixed clamping rod 11. The adjusting clamping rod 12 is arranged on the sliding ring 21. By sliding the sliding ring 21 between the limiting ring 2 and the fixed clamping rod 11, the adjusting clamping rod 12 can be driven to move and change the relative distance from the fixed clamping rod 11, so that the wrench can adapt to the spokes of handwheels of different sizes for clamping, thereby improving the applicability of the wrench.

[0025] In an embodiment, a raised key plate 3 is arranged inside the limiting ring 2, and a key groove 31 for the key plate 3 to be limitedly slidable is arranged on the main rod 1. Through the arrangement of the key plate 3 and the key groove 31, the sliding ring 21 can only slide up and down on the main rod 1 and cannot rotate, so as to keep the adjusting clamping rod 12 and the fixed clamping rod 11 always parallel, and the holding force of the wrench is more stable when turning the handwheel.

[0026] In an embodiment, a threaded hole 4 is opened on the sliding ring 21. A bolt 41 that is threadedly connected in the threaded hole 4 and abuts against the outer surface of the sliding ring 21 is provided. One end of the bolt 41 away from the threaded hole 4 is provided with a lever 42. After the sliding ring 21 slides and adjusts on the main rod 1, by rotating the bolt 41, its end abuts tightly against the outer surface of the sliding ring 21, so as to fix the sliding ring 21 and prevent it from sliding again. The setting of the lever 42 enables the user to better apply a rotational force to the bolt 41.

[0027] In an embodiment, the part of the main rod 1 where the sliding ring 21 is limitedly slidable is cut into a plane on the side facing the bolt 41, and serrated lines 5 for increasing the friction with the bolt 41 are arranged on the plane. The setting of the plane can increase the contact surface between the end of the bolt 41 and the sliding ring 21. Coupled with the serrated lines 5, the locking state of the bolt 41 to the sliding ring 21 is more stable.

[0028] In one embodiment, a receiving groove 6 is further formed on the outer surface of one end of the main rod 1 away from the fixed clamping rod 11. A fixed grip rod 61 received therein is rotatably arranged inside the receiving groove 6. An active barrel sleeve 62 is rotatably sleeved on the fixed grip rod 61. Since it is sometimes necessary to rotate the handwheel multiple times when controlling the steam valve, the conventional straight rod state of the main rod 1 is not easy to operate. Therefore, the fixed grip rod 61 can be rotated out of the receiving groove 6, and then the active barrel sleeve 62 can be held by hand to drive the rotation of the main rod 1, improving the operation convenience.

[0029] In one embodiment, a convex rod head 7 is arranged at one end of the active barrel sleeve 62 away from the fixed grip rod 61. Side clamping rods 71 are arranged on both sides of the convex rod head 7. A clamping groove 72 for clamping the side clamping rods 71 is arranged in the receiving groove 6. After the wrench is used, by receiving the active barrel sleeve 62 back into the receiving groove 6, and then clamping the side clamping rods 71 in the clamping grooves 72 for fixation, the stability of the storage is ensured.

[0030] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes within the meaning and scope of the equivalent elements of the claims in the present invention.
