Description

Technical Field

[0001] The utility model relates to the technical field of handwheel valve switch assisting tools, and particularly relates to a five-wheel handrail handwheel valve switch assisting tool. Background Technique

[0002] The handwheel valve is a traditional type of valve that controls the flow of fluid in a pipeline through manual operation. The design of the handwheel valve is simple and reliable, making it very common in industries such as metallurgy and mining. The working principle of the handwheel valve mainly drives the valve flap to move on the valve seat by manually rotating the handwheel, thereby changing the channel state of the pipeline and enabling the fluid to flow or be blocked.

[0003] However, when the valve has not been used for a long time, the valve often rusts. Coupled with the small rotation radius of the handwheel valve in the existing technology, there are problems such as the valve being unable to be opened, difficult to open, and difficult to lock after being opened when manually rotating the handwheel. Content of the Utility Model

[0004] In view of the above technical problems, the utility model provides a five-wheel handrail handwheel valve switch assisting tool.

[0005] In order to achieve the above purpose, the technical solution of the utility model is specifically as follows:

[0006] A five-wheel handrail handwheel valve switch assisting tool, comprising:

[0007] A nut sleeve;

[0008] An extension rod, threadedly installed at the tail of the nut sleeve;

[0009] A front fixing piece and a rear fixing piece, vertically arranged at the front end of the nut sleeve to form an F-shaped structure, and a screw hole is provided on the rear fixing piece;

[0010] A movable piece, vertically arranged between the front fixing piece and the rear fixing piece, with an adjusting screw vertically arranged on its side wall, and the adjusting screw is fitted and installed in the screw hole on the rear fixing piece, so that when the adjusting screw is rotated, the movable piece can move back and forth to clamp the valve handwheel.

[0011] The movable piece and the adjusting screw can rotate relative to each other.

[0012] The utility model further includes:

[0013] A lead screw, with an annular groove provided at the front end;

[0014] A clamping piece, perpendicularly arranged with the lead screw at the front end of the lead screw and sleeved on the annular groove;

[0015] Among them, the nut sleeve is provided with internal threads, and the threaded part at the tail of the lead screw is installed inside the nut sleeve.

[0016] An assembly round hole is arranged in the middle part of the clamping and blocking piece for fitting and installation with the annular groove; clamping notches are respectively arranged at both ends of the clamping and blocking piece for clamping with the internal spokes of the valve handwheel.

[0017] The head of the lead screw is provided with an external hexagon for easy rotation and force application.

[0018] The beneficial effects of the present utility model are as follows:

[0019] 1. The present utility model can be fixed on the valve handwheel. By pulling the extension rod to drive the rotation of the valve handwheel, the rotation radius is increased, and the torque is increased, thus solving the problem that it is laborious due to the short rotation radius of the valve handwheel.

[0020] 2. By adjusting the movable blocking piece, the present utility model can be compatible with various scenarios where the outer diameters of different handwheels are different, improving the flexibility and compatibility of the present utility model.

[0021] 3. By setting the adjustable wheel support blocking piece, the present utility model can be compatible with valve handwheels of various wheel support specifications, improving the compatibility of the present utility model with different specifications of valve handwheels.

[0022] 4. By setting the extension rod, the rotation radius of the present utility model can be increased, thus achieving a better labor-saving effect. The detachable design also enables the present utility model to be used in a narrow space, improving the flexibility of the present utility model.

[0023] 5. The present utility model clamps the internal spokes of the valve handwheel through the clamping and blocking piece, enabling the maximum mutual locking between the tool and the valve handwheel.

[0024] 6. There is a circular groove in the middle of the movable blocking piece, which can be fitted with the adjusting screw rod. The position of the movable blocking piece can be adjusted back and forth through the adjusting screw rod. The movable blocking piece does not participate in rotation. This adjusting structure can match the thickness of the outer rings of various handwheels, improving the compatibility of the tool.

[0025] 7. The extension rod increases the rotation radius of the handwheel when applying force, thus achieving a labor-saving effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the specific implementation manners and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following descriptions, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0032] As Figures 1 to 3 shown, a five-wheel handwheel valve switch assisting tool includes: a nut sleeve 3; an extension rod 6 threadedly installed at the tail of the nut sleeve 3; a front fixing retaining piece 7 and a rear fixing retaining piece 8 vertically arranged at the front end of the nut sleeve 3 to form an F-shaped structure, and a threaded hole is provided on the rear fixing retaining piece 8; a movable retaining piece 4 vertically arranged between the front fixing retaining piece 7 and the rear fixing retaining piece 8, with an adjusting screw rod 5 vertically arranged on its side wall, and the adjusting screw rod 5 is fitted and installed in the threaded hole on the rear fixing retaining piece 8, so that when the adjusting screw rod 5 is rotated, the movable retaining piece 4 can move back and forth to realize the clamping of the valve handwheel, and the movable retaining piece 4 and the adjusting screw rod 5 can rotate relative to each other.

[0033] As Figure 1 , Figure 3 and Figure 4 shown, the present utility model further includes: a lead screw 2 with an annular groove 9 provided at the front end; a clamping retaining piece 1 perpendicularly arranged with the lead screw 2 at the front end of the lead screw 2 and sleeved on the annular groove 9; wherein, an internal thread is provided inside the nut sleeve 3, and the tail of the lead screw 2 is threadedly installed inside the nut sleeve 3.

[0034] As Figure 5 shown, an assembly round hole 101 is provided at the middle part of the clamping retaining piece 1 for fitting and installing with the annular groove 9; clamping notches 102 are respectively provided at both ends of the clamping retaining piece 1 for clamping with the internal spokes of the valve handwheel.

[0035] As Figure 1 and Figure 4 shown, an external hexagon is provided at the head of the lead screw 2 to facilitate rotation and force application.

[0036] When the utility model is in use, the front fixing flap 7 and the rear fixing flap 8 are clamped on the valve handwheel. The adjusting screw rod 5 is rotated to make the movable flap 4 clamp the handwheel. Then, the external hexagon at the head of the screw rod 2 is rotated to make the screw rod 2 continuously move towards the center of the valve handwheel until the clamping notches 102 at both ends of the clamping flap 1 are clamped on the inner spokes of the valve handwheel. At this time, the utility model is completely locked with the valve handwheel. Preferably, the extension rod 6 is rotated to extend the nut sleeve 3. At this time, the operator pulls the extension rod 6 and the valve handwheel starts to rotate. Among them, in a narrow space, it can be considered not to rotate the extension rod 6 for extension. According to actual needs, it is decided whether to use the extension rod 6, so as to achieve a better labor-saving effect.
