Description

Technical Field

[0001] The utility model relates to the field of general tools, in particular to a special wrench for disassembling a ball valve. Background Art

[0002] Ball valves are widely used in compressed air and water supply pipelines at various locations in mines. Due to the humid underground environment and poor water quality, ball valves are very easy to rust. The rust includes difficulties in opening and closing caused by rust on the outside of the ball valve, and damage and leakage of the ball valve caused by rust on the inside of the ball valve. In addition, since some ball valves lack an external hexagonal structure, it is very difficult to disassemble and replace the ball valve. In the existing technology, the disassembly of this type of ball valve is to use a pipe wrench to obliquely lock the outer jacket of the ball valve core and the valve core outer jacket. This locking method is very easy to slip, making the ball valve difficult to remove. It can only be cut with an angle grinder. This disassembly method often requires additional operations such as re-threading the pipe end, which makes the disassembly of the ball valve very cumbersome. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a special wrench for dismantling ball valves which has a simple structure, is specially used for dismantling various ball valves, and is easy to use.

[0004] The device includes a grip handle, which is the gripping component and assembly basis of the device;

[0005] The front end of the grip handle is provided with a pipe sleeve; the pipe sleeve is used to be sleeved or buckled onto the pipe;

[0006] An assembly connecting rod is provided on the gripping handle, a pressing connecting rod is provided at the end of the assembly connecting rod, and a ball valve top block is also provided at the end of the pressing connecting rod.

[0007] The effect achieved thereby is that the pipe sleeve is partially sleeved on the pipe, and the ball valve top block on its side is pressed against the valve core outer sleeve of the ball valve;

[0008] By rotating the assembly connecting rod, the ball valve can be pushed, that is, the valve core part can be disassembled.

[0009] The beneficial effects of the utility model are: the utility model has a simple structure, flexible assembly, low manufacturing and maintenance costs, and realizes rapid disassembly of the ball valve through a simple structure. It is particularly suitable for ball valves that lack assembly and disassembly sleeves and for use in work sections where ball valves are frequently replaced. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Reference Figure 1 、 Figure 2 The utility model discloses a special wrench for disassembling a ball valve, comprising a gripping handle 2, which is a gripping component and an assembly base of the device;

[0016] The front end of the gripping handle 2 is provided with a pipe sleeve 1; the pipe sleeve 1 is used to be sleeved or buckled onto the pipe;

[0017] An assembly connecting rod 8 is provided on the gripping handle 2 , a pressing connecting rod 3 is provided at the end of the assembly connecting rod 8 , and a ball valve top block 4 is also provided at the end of the pressing connecting rod 3 .

[0018] The effect achieved in this way is that the pipe sleeve 1 is partially sleeved on the pipe, and the ball valve top block 4 on its side is pressed against the valve core outer sleeve of the ball valve;

[0019] By rotating the assembly connecting rod 8, the ball valve can be pushed, that is, the valve core part can be disassembled.

[0020] Furthermore, the pipe sleeve 1 is in the form of an open hook body, and the pipe sleeve 1 is provided with various specifications;

[0021] The pipe sleeve 1 is threadedly connected to the grip handle 2.

[0022] The effect achieved thereby is that the pipe sleeve 1 part can be easily buckled on the pipe and provide force support for subsequent rotation movements.

[0023] Furthermore, the ball valve top block 4 is in the form of a supporting fork.

[0024] The effect achieved thereby is that the supporting fork portion is convenient for pressing against the outer sleeve position of the ball valve core.

[0025] In Example 1, the assembly link 8 is integrally provided on the gripping handle 2, and the pressing link 3 is obliquely provided at the end of the assembly link 8, and the setting direction is upwardly inclined.

[0026] The effect achieved in this way is that the position of each unit corresponds to the pipeline and the ball valve.

[0027] In Example 2, a plurality of spline grooves 6 are arranged in an array on the gripping handle 2 , and the assembly connecting rod 8 is a spline shaft, and the assembly connecting rod 8 is arranged in the spline groove 6 for insertion and removal.

[0028] The effect achieved by this is as shown in the accompanying drawings of the specification. Figure 1 As shown, the assembly connecting rod 8 can be inserted into any spline groove 6, and the axial position of the ball valve top block 4 can be adjusted accordingly;

[0029] During insertion, the orientation of the push rod 3 is determined or flexibly adjusted by adjusting the assembly position between the keyway and the key shaft. This means the device can be used to disassemble ball valves of a wider variety of specifications, making installation more convenient. The position of the ball valve top block 4 can be flexibly adjusted based on the position of the pipe sleeve 1.

[0030] In embodiment 3, corresponding to the multiple spline grooves 6 , a plurality of positioning screw holes 7 are opened on the upper portion of the gripping handle 2 , and positioning bolts are arranged in the positioning screw holes 7 .

[0031] The effect achieved thereby is to lock and limit the horizontal position of the spline shaft.

[0032] Furthermore, the end of the gripping handle 2 is provided with an anti-slip rubber sleeve 5.
