DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a valve handle wrench used for manually opening and closing a valve.

[0002]

2. Description of the Related Art Manual opening and closing operations of valves used in thermal power plants and the like are performed using tools.
As a tool, a wilkey is conventionally known. That is, as shown in FIG.
1 and a pair of holding pieces 1 formed at the tip of the handle 11
The valve handle 2 is held and fixed to the valve handle 2 using a pair of holding pieces 12, and the handle 11 is operated to rotate the valve handle 2.

[0003]

In this prior art, the wheel key 1 must be changed and the valve handle 2 must be turned, so that continuous operation cannot be performed. Further, since the wheel key 1 applies a force to a part of the valve handle 2, there is a risk that the valve handle 2 may be broken. Furthermore, since the key 1 is made of iron or stainless steel, it is heavy and difficult to handle, and there is a risk of injury to hands and feet, and the nameplate may be bent or broken when the key 1 is hooked. Therefore, in this conventional technique, there is a problem that work efficiency is poor and safety is lacking.

The present invention has been made for the purpose of solving such problems of the prior art.

[0005]

Means for solving the above problems will be described below with reference to FIG. 1 corresponding to an embodiment.
explain. According to the present invention , the frame 4 is formed at the tip of the handle 3, and one end 41 of the frame 4 is
1 is wound around the pin 44 erected and folded
Winding wound around the attachment part 51 and the valve handle 2
The short side of the winding part 52 formed from the winding part 52
At both ends of the inner circumference, do not come off the valve handle 2
A projection 52B is provided around the center of the inner periphery.
Groove 52C fitted with protrusion 21 protruding from handle 2
Is one end of the belt 5 provided fixed to the frame 4, though the other end of the belt 5 is inserted, wrapped around the inner circumference of the belt 5 on the outer periphery of the valve handle 2, by rotating the handle 3 frame 4 Is pressed against the outer periphery of the belt 5 to fix the belt 5 to the valve handle 2, and the handle 3 is operated to rotate the valve hand 2.

[0006] In such a structure, there is no need to change the handle 3, so that continuous operation is possible. Since the belt 5 is wound around the valve handle 2 and fixed, no force is applied to only a part of the valve handle 2 and there is no danger of breaking the valve handle 2.

[0007]

FIG. 1 is a diagram showing an embodiment of the present invention. In FIG. 1, 3 is a handle, 4 is a frame, 5 is a belt, and 6 is a belt pressing plate.

The handle 3 is made of aluminum, and its length is
200 to 350 mm. Since it is made of aluminum, it is lightweight and easy to handle.

The frame 4 is made of aluminum and is formed integrally with the handle 3 at the tip of the handle 3. The frame 4 has a width of 60 to 80 mm, a height of 50 to 65 mm, and a hollow portion 43 of 35 to 45 mm square. A pin 44 to which one end of the belt 5 is fixed is mounted on one end 41 of the frame 4 (see FIG. 2).

The belt 5 is made of nylon, and includes a mounting portion 51 wound around the pin 44 and folded back, and a winding portion 52 wound around the valve handle 2. One end of the winding portion 52 is attached to the mounting portion 5
1 by sewing or gluing, and the wrapped portion 52
Is inserted through the frame 4, that is, the hollow portion 43.

The winding portion 52 is composed of a strip 52A and two projections 52B. The projections 52B are provided at both ends on the inner side in the short side direction of the strip 52A so as not to come off from the valve handle 2. Are installed at regular intervals,
A groove 52C that fits with the protrusion 21 protruding from the valve handle 2 is provided at the center of the inner periphery (see FIG. 3). The protruding portion 52B places the string 53 on a belt-shaped thing,
The band is folded and sewn. The length of the belt 5 is 70 to 120 cm and its width is 35 to 45 mm. The height of the projection 52B is 5 to 10 mm. Note that the attachment portion 51 may also serve as the belt-shaped portion 52A.

The belt holding plate 6 is made of rubber and is provided on the belt insertion / exit side O of the frame 4 and one end thereof is fixed to an exit side surface 41O of one end 41 of the frame 4 by a bolt 7 and a washer 8 (see FIG. 1). (See FIG. 2). A part of the hollow portion 43 of the frame 4 is closed by the belt pressing plate 6, and the inner periphery of the belt 5 is in contact with the other end of the belt pressing plate 6. Due to this contact, the outer periphery of the belt 5 is in contact with the inside of the other end 42 of the frame 4. The other end of the belt pressing plate 6 is formed in a tapered shape in order to increase a contact area with the belt 5. Connect the belt 5 to the belt insertion exit side O
, The belt pressing plate 6 does not become an obstacle, but when it is pushed into the belt insertion entrance side I, it becomes an obstacle. Therefore, the belt 5 inserted through the frame 4
Does not separate from the frame 4 during movement or the like.

According to the size of the valve handle 2, the size of the loop of the belt 5 is adjusted, the belt 5 is put on the valve handle 2, and the positions of the projections 52B and the grooves 52C are adjusted. Is wound around the inner circumference of the belt 5. The other end of the belt 5 is pulled, the handle 3 is rotated to the belt insertion / exit side O, and the inlet side surface 42I of the other end 42 of the frame 4 is pressed against the outer periphery of the belt 5 to fix the belt 5 to the valve handle 2. . Operate the handle 3,
The valve handle 2 is rotated (see FIG. 4). To change the position of the handle 3, loosen the belt 5
To move.

Since there is no need to change the handle 3,
Continuous operation is possible, and the work efficiency of manual opening and closing operation is improved. Also, wrap the belt 5 around the valve handle 2,
Since the valve handle 2 is fixed, no force is applied to only a part of the valve handle 2, and there is no danger of breaking the valve handle 2 and safety is improved.

[0015]

As described above, the present invention provides:
The distal end of the handle, the frame is formed, at one end of the frame, wrapped around the pins which are laid on the end portion folding
Wrapped around the fitting and valve handle
And a short side of the wound portion
At both ends of the inner circumference in the direction does not come off from the valve handle
A protrusion is provided around the center of the inner periphery of the valve.
A groove is provided to fit with the protrusion protruding from the handle.
One end of which belt is fixed to the frame, the other end of the belt have been inserted, wrapped around the inner circumference of the belt on the outer periphery of the valve handle, the other end of the frame by rotating the handle The belt is fixed to the valve handle by pressing against the outer periphery of the belt, and the handle is operated to rotate the valve handle. Therefore, since it is not necessary to change the handle, continuous operation is possible. Since the belt is wound around and fixed to the valve handle, no force is applied to only a part of the valve handle, and there is no danger of breaking the valve handle. Therefore, according to the present invention, the effect of improving the efficiency and safety of the manual opening / closing operation of the valve is obtained.
