Description

Technical Field

[0001] The utility model belongs to the technical field of wrenches, and particularly relates to an anti-slip tongue-shaped stopper valve wrench. Background Art

[0002] Valves are widely used in the installation sites of process industries such as petroleum, chemical, fertilizer, and pharmaceutical, and are important control components in fluid transportation systems. During the process of valve opening and closing, due to the frequent opening and closing of the valve and the corrosion and high temperature of the medium in the pipeline, the valve will usually have problems such as wear, scaling, and increased friction coefficient of the sealing parts, which will cause the valve to become stuck and make it difficult to open and close the valve. In this way, it is not only very laborious to manually operate the valve only through the handwheel of the valve, but the valve cannot be closed or fully opened normally.

[0003] At present, factories usually use steel pipes welded into an F-shaped valve wrench as a force rod for operators to open and close valves. When using this F-shaped valve wrench to open and close valves, although it can save effort, it is also easy to slip. When encountering a valve that is difficult to open and close, it is necessary to use more force to open and close the valve, which makes it more likely to slip and injure people. In addition, in an emergency, it is necessary to quickly cut off the input or output of certain materials. However, due to the slippage of the wrench, the valve cannot be continuously opened or closed, which reduces the speed of opening and closing the valve, delaying the time to deal with the emergency and causing greater safety accidents.

[0004] Therefore, how to provide an anti-slip tongue-shaped stopper valve wrench for clamping the valve handwheel to prevent slipping is a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

The valve wrench of the utility model clamps and limits the valve handwheel 6 through the wrench head 1, the first force column 2 and the second force column 3, and applies a force to the main body straight rod 4 to open and close the valve, and the greater the force applied, the tighter the clamping of the valve handwheel 6 is, thereby preventing the valve wrench from detaching from the valve handwheel 6 during operation.

[0030] In some possible embodiments, the first load-bearing column 2 is formed by integrally forging a first column 21 and a first tongue-shaped stopper 22; the bottom end of the first column 21 is welded to the upper surface of one end of the wrench head 1, and the first column 21 is provided with a first tongue-shaped stopper 22, the first column is clamped with the inner side of the valve handwheel and the first tongue-shaped stopper 22 is against the valve handwheel 6.

[0031] Those skilled in the art can understand that the first force-bearing column 2 is formed by integrally forging the first column 21 and the first tongue-shaped stopper 22, has high strength, is durable and has a long service life, and the first tongue-shaped stopper 22 is arranged at the top end of the first column 21, the first column 21 is engaged with the inner side of the valve handwheel 6 and the first tongue-shaped stopper 22 is against the valve handwheel 6 to prevent the first column 21 and the valve handwheel 6 from slipping during the force application process, and the first tongue-shaped stopper 22 is used to limit and fix the valve handwheel 6; in addition, the bottom end of the first column 21 is vertically welded to the upper surface of the wrench head 1 to increase the force-bearing area.

[0032] In some possible embodiments, the included angle between the central axis of the first tongue-shaped stopper 22 and the central axis of the wrench head 1 is 35° to 95°.

[0033] like Figure 2-3 As shown, the first column 21 is cylindrical, the first tongue-shaped stopper 22 is arranged on the first column 21 and the protrusion is facing the direction of the main straight rod 4, and the angle between the central axis of the first tongue-shaped stopper 22 and the central axis of the wrench head 1 is set to be 35°~95°. When the valve wrench is used to open and close the valve, the first tongue-shaped stopper 22 can clamp the valve to bear the force and prevent sliding.

[0034] In some possible embodiments, a first rubber sleeve 23 is sleeved on the cylindrical surface of the first column 21 .

[0035] This is because the first rubber sleeve 23 is sleeved on the cylindrical surface of the first column 21, and the friction of the rubber can further enhance the anti-skid property of the first column 21, thereby improving the anti-skid performance of the valve wrench; at the same time, it can also reduce the possibility of sparks generated by the collision between the valve wrench and the valve handwheel 6, thereby improving the safety of the valve wrench. In addition, the rubber sleeve is a low-value wearing part, and can be easily replaced at any time after being damaged.

[0036] In some possible embodiments, the second force-bearing column 3 is formed by integrally forging a second column 31 and a second tongue-shaped stopper 32; the bottom end of the second column 31 is welded to the upper surface of the other end of the wrench head 1, and the second column 31 is provided with a second tongue-shaped stopper 32, and the second column 31 is clamped with the outer side of the valve handwheel 6 and the second tongue-shaped stopper 32 is against the valve handwheel 6.

[0037] In some possible embodiments, the included angle between the central axis of the second tongue-shaped stopper 32 and the central axis of the wrench head 1 is 15° to 75°.

[0038] In some possible embodiments, a second rubber sleeve 33 is sleeved on the cylindrical surface of the second column 31 .

[0039] Those skilled in the art will appreciate that, similarly, Figure 2-3 As shown, the second force-bearing column 3 is forged by an integral body of the second column 31 and the second tongue-shaped stopper 32, and the second force-bearing column 3 is arranged parallel to the first force-bearing column 2, the protruding portion of the second tongue-shaped stopper 32 is away from the direction of the main straight rod 4, and the angle between the central axis of the second tongue-shaped stopper and the central axis of the wrench head 1 is 15° to 75°. Preferably, the angle between the central axis of the first tongue-shaped stopper 22 and the central axis of the wrench head 1 is 65°, and the angle between the central axis of the second tongue-shaped stopper 32 and the central axis of the wrench head 1 is 45°, so that the first column 21 clamps the inner side of the valve handwheel 6, and the second column 31 clamps the outer side of the valve handwheel 6, and the first tongue-shaped stopper 22 and the second tongue-shaped stopper 32 are used to limit and fix the valve handwheel 6 to prevent the valve handwheel 6 from slipping.

[0040] In some possible embodiments, one end of the main straight rod 4 is welded to the other end of the wrench head 1 , and an angle between a central axis of the main straight rod 4 and a central axis of the wrench head 1 is 15° to 75°.

[0041] In some possible embodiments, the central axis of the main straight rod 4 is parallel to the central axis of the second tongue-shaped stopper 32 .

[0042] This is because one end of the main straight rod 4 is welded to the other end of the wrench head 1, so that the main straight rod 4 and the wrench head 1 form an "L"-shaped structure. When the central axis of the main straight rod 4 is parallel to the central axis of the second tongue-shaped stopper 32, the main straight rod 4 can apply a force to the second load-bearing column 3, and when the angle between the central axis of the main straight rod 4 and the central axis of the wrench head 1 is 45°, the force arm for applying the force is the longest, thereby achieving a labor-saving effect.

[0043] In some possible embodiments, the handle 5 is made of rubber material.

[0044] Those skilled in the art will appreciate that the handle 5 is made of rubber material, which can increase friction, further improve the anti-slip property of the valve wrench, and improve the grip feel of the operator.

[0045] The working principle of the utility model anti-skid tongue-shaped stopper valve wrench is as follows: the first force-bearing column 2 is placed on the inner side of the valve handwheel 6, the second force-bearing column 3 is placed on the outer side of the valve handwheel 6, and the valve handwheel 6 is locked in combination with the wrench head 1. The operator holds the handle 5 on the main body straight rod 4 and rotates it clockwise to close the valve; and rotates it counterclockwise to open the valve.
