Description

Technical Field

[0001] This utility model relates to the field of valve opening and closing technology, specifically to a manual valve opening and closing tool. Background Technology

[0002] During the power plant's production and operation phase, numerous manual valves are required in various media pipeline systems for energy isolation. Operators frequently need to open and close these valves during start-up, shutdown, and inspection. The commonly used valve opening and closing tool is the F-type wrench. Because the manual valves to be operated vary in size, different sizes of F-type wrenches need to be frequently changed when operating the valves.

[0003] A tool for assisting valve opening and closing, disclosed in Chinese invention patent application publication CN218644914U, belongs to the technical field of valve switching tools. It includes a reinforcing rod with an inner rod fixed at one end and an outer rod near the inner rod. The inner and outer rods are parallel to each other and are used to cooperate in opening and closing the valve. When the valve needs to be opened, the operator moves the reinforcing rod, placing the inner rod at the connection position between the handwheel connecting rib and the handwheel ring, and placing the outer rod at the outer edge of the handwheel ring. Then, moving the reinforcing rod rotates the valve, allowing for convenient opening and closing of infrequently used valves. This technical solution uses a movable outer rod to adapt to different valves; however, the outer rod is connected with a nut when its connection position is changed. When the position needs to be changed, the nut must be separated from the outer rod, and the position of the outer rod must be adjusted before it can be adapted, which is time-consuming. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a manual valve opening and closing tool, which solves the problem of wasting time by installing and removing nuts when adjusting the position of the outer rod in the prior art.

[0005] Technical solution

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a manual valve opening and closing tool, including a torsion bar, wherein a set of semi-through snap-fit ​​grooves for snap-fit ​​are provided on the outer surface of the torsion bar, and a sliding groove communicating with the snap-fit ​​grooves is provided on the outer surface of the torsion bar. A fixed claw pin is fixedly installed at the lower end of one end of the torsion bar, and a movable claw pin is inserted into the snap-fit ​​groove, and the movable claw pin is slidably connected with the sliding groove.

[0007] Furthermore, the snap-fit ​​groove and the sliding groove are located on the same axis, and the cross-sectional shape of the snap-fit ​​groove is rectangular.

[0008] Furthermore, the movable claw pin includes a threaded shaft, the outer surface of which is threadedly connected to a snap-fit ​​block inserted into a snap-fit ​​groove, and a baffle is threadedly connected to the threaded shaft below the sliding groove.

[0009] Furthermore, the locking groove is located below the torsion bar, and the sliding groove is located on the side wall of the torsion bar. The sliding groove and the locking groove are connected and communicate with each other through a connecting groove. The sliding groove protrudes outward parallel to the axis of the torsion bar. The movable claw pin includes a ball head rotatably connected in the sliding groove. One end of the ball head is fixedly installed with a locking rod extending to the outside of the torsion bar. The locking rod and the ball head are slidably connected with the locking groove.

[0010] Furthermore, the sliding groove is horizontally opened from the side where the torsion bar is installed and fixed with the claw pin, and the end of the torsion bar located at the end where the claw pin is installed is threaded with an end cap.

[0011] Furthermore, an extension rod is threaded to the end of the torsion bar away from the fixed claw pin.

[0012] Furthermore, a rotating ring is rotatably connected to the end of the extension rod away from the torsion bar, and a handle is fixedly installed on the outer surface of the rotating ring.

[0013] Furthermore, a handrail is fixedly installed at the end of the torsion bar away from the fixed claw pin.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This manual valve opening and closing tool is designed to allow the locking block to be pulled out of the locking groove, and the threaded shaft to slide along the sliding groove. When it slides to the designated locking groove, the locking block is moved downward so that it can lock into the new locking groove, thereby achieving the effect of quickly changing the position of the moving claw pin and fixing the moving claw pin.

[0016] 2. This manual valve opening and closing tool features a locking groove located below the torsion bar and a sliding groove located on the side wall of the torsion bar. The sliding groove and the locking groove are connected and penetrate each other via a connecting groove. The sliding groove protrudes outward parallel to the axis of the torsion bar. The movable claw pin includes a ball head rotatably connected within the sliding groove. One end of the ball head is fixedly fitted with a locking rod extending to the outside of the torsion bar. The locking rod and the ball head are slidably connected to the locking groove, thus misaligning the locking groove and the sliding groove. Neither the locking groove nor the sliding groove completely penetrates the torsion bar, thereby ensuring the strength of the torsion bar while facilitating the replacement of the movable claw pin position.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1, see Figures 1-3 The manual valve opening and closing tool includes a torsion bar 1. The outer surface of the torsion bar 1 has a set of semi-through locking grooves 2 for locking. The outer surface of the torsion bar 1 has a sliding groove 3 that communicates with the locking grooves 2. A fixed claw pin 4 is fixedly installed at the lower end of one end of the torsion bar 1. A movable claw pin 5 is inserted into the inside of the locking groove 2. The movable claw pin 5 is slidably connected to the sliding groove 3. By setting the movable claw pin 5, it can slide in the sliding groove 3. When it slides to a designated position, it can lock into the locking groove 2, thereby enabling rapid movement of the movable claw pin 5 and fixing the position of the movable claw pin 5.

[0024] The snap-fit ​​groove 2 and the sliding groove 3 are located on the same axis. The cross-sectional shape of the snap-fit ​​groove 2 is rectangular. By restricting the shape of the snap-fit ​​groove 2, it can be ensured that the snap-fit ​​groove 2 and the snap-fit ​​block 502 have sufficient connection strength.

[0025] The movable claw pin 5 includes a threaded shaft 501, and a snap-fit ​​block 502 that is inserted into the snap-fit ​​groove 2 is threadedly connected to the outer surface of the threaded shaft 501. A baffle 503 is threadedly connected to the threaded shaft 501 below the sliding groove 3. This arrangement facilitates the assembly and positioning of the movable claw pin 5.

[0026] A handrail 10 is fixedly installed at the end of the torsion bar 1 away from the fixed claw pin 4. The handrail 10 facilitates the operator to exert force.

[0027] During use, the snap-fit ​​block 502 is pulled out from the snap-fit ​​groove 2, and the threaded shaft 501 slides along the sliding groove 3. When it slides to the designated snap-fit ​​groove 2, the snap-fit ​​block 502 is moved downward so that the snap-fit ​​block 502 can snap into the new snap-fit ​​groove 2, thereby achieving the effect of quickly changing the position of the moving claw pin 5 and fixing the moving claw pin 5.

[0028] Example 2, see Figure 4 The manual valve opening and closing tool includes a torsion bar 1. The outer surface of the torsion bar 1 is provided with a set of semi-through snap-fit ​​grooves 2 for snap-fit. The outer surface of the torsion bar 1 is provided with a sliding groove 3 that communicates with the snap-fit ​​grooves 2. A fixed claw pin 4 is fixedly installed at the lower end of one end of the torsion bar 1. A movable claw pin 5 is inserted into the inside of the snap-fit ​​groove 2. The movable claw pin 5 is slidably connected to the sliding groove 3.

[0029] The locking groove 2 is located below the torsion bar 1, and the sliding groove 3 is located on the side wall of the torsion bar 1. The sliding groove 3 and the locking groove 2 are connected and pass through each other through the connecting groove 6. The sliding groove 3 protrudes outward parallel to the axis of the torsion bar 1. The movable claw pin 5 includes a ball head 504 rotatably connected in the sliding groove 3. One end of the ball head 504 is fixedly installed with a locking rod 505 extending to the outside of the torsion bar 1. The locking rod 505 and the ball head 504 are slidably connected to the locking groove 2, and the locking groove 2 and the sliding groove 3 are misaligned. Neither the locking groove 2 nor the sliding groove 3 completely penetrates the torsion bar 1, so as to ensure the strength of the torsion bar 1 while making it easy to change the position of the movable claw pin 5.

[0030] The sliding groove 3 is horizontally opened from the side where the torsion bar 1 is installed with the fixed claw pin 4. The end of the torsion bar 1 where the fixed claw pin 4 is installed is threadedly connected to the end cap 506. This arrangement facilitates the assembly of the movable claw pin 5.

[0031] The end of the torsion bar 1 away from the fixed claw pin 4 is threadedly connected to an extension rod 7. By adjusting the extension rod 7, the torque applied can be changed, thereby making it easier to rotate the valve.

[0032] The end of the extension rod 7 away from the torsion bar 1 is rotatably connected to a rotating ring 8. A handle 9 is fixedly installed on the outer surface of the rotating ring 8. The handle 9 makes it easier for the operator to grip the handle and thus apply force more effectively.

[0033] In use, the ball head 504 is rotatably connected in the sliding groove 3 and slides to the designated connecting groove 6. By rotating the locking rod 505, the locking rod 505 enters the designated locking groove 2 through the connecting groove 6, and the locking rod 505 is horizontally slid to lock into the locking groove 2, thereby quickly achieving the effect of changing the position of the moving claw pin 5.

[0034] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
