Description

Technical Field

[0001] This utility model belongs to the technical field of valve operating tools, specifically a multi-jaw positioning valve wrench. Background Technology

[0002] In industrial settings such as petrochemical and refining plants, the frequent operation and maintenance of valves are core aspects of ensuring production safety. Gate valves, globe valves, and other equipment used extensively on-site often suffer from problems such as rust, coking, and deformation on their outer surfaces due to long-term exposure to high-temperature, high-pressure, and corrosive media. Although traditional single-jaw fixed wrenches can achieve adjustment, in actual applications, there are a large number of non-standard valves and irregularly shaped valve bodies caused by deformation in refining plants. The limited adjustment range of traditional wrenches is difficult to effectively match, and slippage is likely to occur during operation, even causing damage to the valve stem or handwheel. Utility Model Content

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] As attached Figure 1 To be continued Figure 5 As shown:

[0023] Example 1: This utility model provides a multi-claw positioning valve wrench, including a wrench body 1. The wrench body 1 has a rotating ring 2 rotatably connected inside. The bottom of the rotating ring 2 has a fixedly connected mounting ring 3. The outer ring wall of the mounting ring 3 has a recessed receiving chamber 4. The receiving chamber 4 has annularly distributed movable claws 5 inside. The bottom of the movable claws 5 has a claw groove 6. The top of the receiving chamber 4 has a mounting notch 7. The mounting notch 7 is located between two adjacent movable claws 5. The movable claws 5 enter the receiving chamber 4 through the mounting notch 7.

[0024] It also includes a multi-jaw positioning component, which is installed in a ring on the top of the mounting ring 3 and fixes the movable jaw 5 in the receiving chamber 4. One end of the wrench body 1 is provided with a wrench handle 8.

[0025] It should be noted that the wrench body 1 has a rotating ring 2 inside it, and a mounting ring 3 at the bottom of the rotating ring 2. The movable claw 5 is placed inside the mounting ring 3 through the mounting notch 7, allowing it to move within the receiving chamber 4. It can also be adjusted according to the position of the valve, and different numbers of movable claws 5 can be installed for different types of valves. When the claw groove 6 of the movable claw 5 is engaged with the valve, the movable claw 5 can be fixed to the mounting ring 3 by the multi-claw positioning component. Rotating the wrench body 1 can rotate the valve. Compared with traditional handles, it can adapt to different valves and improve the flexibility of the valve handle.

[0026] Specifically, when it is necessary to tighten or loosen the valve, select the corresponding movable claw 5 according to the number of valves that need to be fixed in position, and put the movable claw 5 into the receiving chamber 4 from the installation notch 7 on the mounting ring 3, so that the corresponding groove 11 on the movable claw 5 is locked on the mating retaining ring 10. The movable claw 5 can move on the mating retaining ring 10, so as to adjust according to the specific position of the valve installation and the number of fixed positions. The claw groove 6 on the movable claw 5 is locked on the valve stem.

[0027] In this embodiment, the rotating ring 2 and the mounting ring 3 are provided with through holes 9, and the number of movable claws 5 is not less than three.

[0028] It should be noted that by providing through holes 9 on the rotating ring 2 and the mounting ring 3, the purpose of the through holes 9 is to allow the screw on the valve to pass through the through holes 9, thereby fixing the valve wrench to the valve.

[0029] In this embodiment, an annular locking ring 10 is provided on the bottom wall of the receiving chamber 4, and a corresponding slot 11 is provided at the bottom of the movable claw 5. After the movable claw 5 is placed into the receiving chamber 4, the corresponding slot 11 and the locking ring 10 cooperate with each other. Vertical positioning holes 12 are provided on the mounting ring 3, the locking ring 10 and the movable claw 5.

[0030] It should be noted that the corresponding slot 11 is engaged with the mating ring 10. The purpose of setting the two is that after the movable claw 5 is placed in the receiving chamber 4, it is limited by the mating ring 10, so that the movable claw 5 can only move on the mating ring 10 and will not move outward or inward, thereby improving the stability of the movable claw 5 after positioning.

[0031] In this embodiment, the multi-claw positioning assembly includes a concave plate 13, a positioning rod 14, a positioning spring 15, a lifting plate 16, and a pull ring 17. The concave plate 13 is fixedly connected to the top of the mounting ring 3 in a ring shape with the concave plate 13 facing downward. The positioning rod 14 is vertically movably connected to the concave plate 13, and the positioning rod 14 cooperates with the positioning hole 12.

[0032] In this embodiment, the lifting plate 16 is fixedly connected to the positioning rod 14 and is inside the recess of the concave plate 13. The positioning spring 15 is sleeved on the positioning rod 14. One end of the positioning spring 15 abuts against the lifting plate 16 and the other end abuts against the concave plate 13. The pull ring 17 is fixedly connected to the top of the positioning rod 14 and is movably fitted to the top of the concave plate 13.

[0033] It should be noted that the number of concave plates 13 is not less than the number of movable claws 5 and they are evenly spaced. Since the positioning spring 15 is sleeved on the positioning rod 14, when the positioning hole 12 on the movable claw 5 coincides with the positioning hole 12 on the mounting ring 3, the positioning rod 14 is released. At this time, the positioning spring 15, which was originally compressed, gradually returns to its original position and applies a rebound force to the lifting plate 16, which drives the positioning rod 14 to pass downward through the positioning hole 12 on the movable claw 5 and the mounting ring 3, thereby fixing the movable claw 5. When the wrench body 1 drives the rotating ring 2 to rotate, it will also apply force to the movable claw 5, thereby tightening and loosening the valve.

[0034] In this embodiment, the top of the wrench body 1 is provided with a light lamp 18, the wrench handle 8 is connected to the wrench body 1 by a thread, and the outer wall of the wrench handle 8 is covered with a rubber layer 19.

[0035] It should be noted that the purpose of setting up the lighting lamp 18 is to turn on the lighting lamp 18 in the case of a low light environment so that the workers can work better. The rubber layer 19 is set on the wrench handle 8. The rubber layer 19 can withstand high temperature and is non-slip, reducing the slippage during the tightening of the valve and improving work safety.

[0036] In this embodiment, a ratchet 20 is fixedly connected inside the wrench body 1 and on the outer wall of the rotating ring 2. A locking tooth 21 is rotatably connected inside the wrench body 1, and the locking tooth 21 cooperates with the ratchet 20. An elastic pin 22 is provided on the side of the locking tooth 21 away from the ratchet 20.

[0037] It should be noted that the elastic pin 22 is made of spring steel and has a built-in return spring. A guide hole is pre-set inside the wrench body 1, and the elastic pin 22 can move axially in the guide hole. When the wrench handle 8 drives the wrench body 1 to rotate counterclockwise, the locking tooth 21 will not cooperate with the ratchet 20, but will only move on the ratchet 20. When you want to rotate clockwise, the locking tooth 21 cooperates with the ratchet 20, so that the locking tooth 21 drives the wrench body 1 to rotate, and finally applies force to the movable claw 5 to tighten the valve. The continuous back and forth movement realizes the opening and closing of the valve. The above ratchet 20 mechanism adopts existing technology and will not be elaborated on here.

[0038] The embodiments of this utility model are given for the purpose of illustration and description. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
