AI Technical Summary

Technical Problem

When the existing F-type wrench opens the disc manual valve, especially when there is a pressure difference on both sides of the valve, it is easy to be difficult to open due to the short handle. The space around the valve is small, and the support arm is too long, which leads to difficulty in operation.

Method used

A disc-type claw wrench for adjusting a disc-type manual valve is designed, including inner branch pipe, outer sleeve, connecting collar, support arm, V-shaped clamp arm, handle and abutment head. Through the threaded connection between the outer sleeve and the inner branch pipe, the wrench arm can be extended when necessary, and the operating direction can be adjusted by connecting the sleeve to solve the problem of space limitations.

Benefits of technology

It realizes operating the valve without tripping under high torque, which is convenient for opening and closing, and can flexibly adjust the operating direction when space is limited, simplifying the operation process.

Abstract

The utility model discloses a claw wrench for adjusting a disc type manual valve. A common F-shaped spanner is short in spanner handle and not easy to open, so that the F-shaped spanner needs to be operated by multiple persons or sleeved with a steel pipe to extend a supporting arm of the F-shaped spanner, operation is difficult, and meanwhile when the distance between a valve and the periphery is small, operation is difficult due to the fact that the supporting arm is too long. The device comprises an inner branch pipe (2) and an overhanging sleeve (1), a connecting lantern ring (3) is fixed at the end part of the inner branch pipe, the other end of the connecting lantern ring is fixed with a support arm (4), a V-shaped clamping arm (5) is fixed at the end part of the support arm, a pulling handle (7) is fixed at one end of the V-shaped clamping arm, and an abutting head (6) is fixed at the other end of the V-shaped clamping arm; and the outer extending sleeve is sleeved on the inner branch pipe and is in threaded connection with the inner branch pipe. The disc-type manual valve adjusting device is used for adjusting the disc-type manual valve.

Description

Technical Field

[0001] The utility model relates to a claw-shaped spanner for adjusting a disc-type manual valve. Background Art

[0002] When opening a disc-type manual valve in a power plant, an F-type wrench is used. When opening a valve, especially when there is a pressure difference on both sides of the valve, the valve will be relatively tight. The handle of a general F-type wrench is relatively short and not easy to open. It requires multiple people to operate or a steel pipe to extend the arm of the F-type wrench, making it difficult to operate. At the same time, when the space around the valve is small, the arm is too long, which makes it difficult to operate. Utility Model Content

[0003] The utility model aims to solve the above-mentioned technical problems and provides a claw wrench for adjusting a disc-type manual valve.

[0004] The above purpose is achieved through the following technical solutions:

[0005] A claw wrench for adjusting a disc-type manual valve, comprising an inner branch pipe and an outer extension sleeve, wherein a connecting collar is fixed to the end of the inner branch pipe, the other end of the connecting collar is fixed to a support arm, a V-shaped clamping arm is fixed to the end of the support arm, a wrench is fixed to one end of the V-shaped clamping arm, and a butt head is fixed to the other end;

[0006] The outwardly extending sleeve is sleeved on the inner branch pipe and is threadedly connected with the inner branch pipe.

[0007] The claw-type spanner for adjusting the disc-type manual valve has an external thread on the outside of the extension sleeve, and an internal thread matching the external thread of the extension sleeve on the inside of the connecting collar.

[0008] The claw-type spanner for adjusting the disc-type manual valve has a spanner handle of a straight rod structure.

[0009] The claw-type wrench for adjusting the disc-type manual valve has a supporting head of a V-shaped rod structure. Beneficial Effects

[0010] 1. The utility model sets the wrench as a claw type. When in use, the wrench handle is inserted between the wheel disc and the rib rod of the manual valve to hook the valve, and the abutment head abuts against the outer edge of the wheel disc, so that the wrench can withstand a large torque without being disengaged, thereby facilitating the operation of the valve.

[0011] 2. The utility model sets the lever as a straight rod structure, so that the two-way operation of opening and closing the valve can be realized.

[0012] 3. The utility model provides an extension sleeve and an inner branch pipe, so that when the valve is tight, the extension sleeve can be twisted to extend the wrench arm, which is convenient for operation.

[0013] 4. The utility model provides a connecting ring. When the space around the valve is small, the wrench arm of the wrench is too long, which will result in no space for operation. By unscrewing the extension sleeve and threading it in the connecting ring, the operating direction can be changed, which is convenient for operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Attached Figure 1 It is a top view of the utility model;

[0015] Attached Figure 2 It is a rear view of the utility model;

[0016] Attached Figure 3 It is a schematic diagram of the structure used when the valve is open;

[0017] Attached Figure 4 It is a schematic diagram of the structure used when the valve is closed;

[0018] In the figure: 1. extension sleeve; 2. inner branch pipe; 3. connecting ring; 4. support arm; 5. V-shaped clamp arm; 6. abutment head; 7. lever; 8. disc-type manual valve. DETAILED DESCRIPTION

[0019] Reference Figure 1-Figure 2 A claw wrench for adjusting a disc-type manual valve, which comprises an inner branch pipe 2 and an outer extension sleeve 1, a connecting collar 3 is fixed to the end of the inner branch pipe, the other end of the connecting collar is fixed to a support arm 4, the inner branch pipe is welded to the connecting collar, the support arm is welded to the connecting collar, a V-shaped clamp arm 5 is fixed to the end of the support arm, a wrench 7 is fixed to one end of the V-shaped clamp arm, and a butt head 6 is fixed to the other end;

[0020] The outwardly extending sleeve is sleeved on the inner branch pipe and is threadedly connected with the inner branch pipe.

[0021] The claw-type spanner for adjusting the disc-type manual valve has an external thread on the outside of the extension sleeve, and an internal thread matching the external thread of the extension sleeve on the inside of the connecting collar.

[0022] The claw-type spanner for adjusting the disc-type manual valve has a spanner handle of a straight rod structure.

[0023] The claw-type wrench for adjusting the disc-type manual valve has a supporting head of a V-shaped rod structure.

[0024] Working principle: When the valve needs to be opened, refer to Figure 3 , insert the lever between the manual valve's wheel disc and the rib rod to hook the valve, and the abutment head abuts against the outer edge of the wheel disc, and then turn the valve clockwise to allow it to withstand a large torque without disengaging, making it easier to operate the valve;

[0025] When the valve needs to be closed, refer to Figure 4 , insert the handle between the wheel disc and the rib rod of the manual valve to hook the valve, the abutment head rests on the outer edge of the wheel disc, and then turn the valve counterclockwise to close the valve.

[0026] When the space around the valve is small, the wrench arm is too long and there is no space for operation. The valve can be operated by unscrewing the extension sleeve and threading it into the connecting ring. The extension sleeve can be held by hand to change the operating direction, which is convenient for operation.
