Description

Technical Field

[0001] The utility model relates to a driving tool for a butterfly valve in a pit, belonging to the technical field of driving tools for butterfly valves in pits. Background Art

[0002] A butterfly valve, also called a flap valve, is a simple-structured regulating valve. A butterfly valve used for switching control of media in low-pressure pipelines refers to a valve whose closing member (valve flap or butterfly plate) is a disc and rotates around the valve shaft to achieve opening and closing. The valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil products, liquid metals, and radioactive media, and mainly plays a role of cutting off and throttling in pipelines.

[0003] Figure 1 As shown in the figure, it is a butterfly valve applied in a pit in a chemical plant. The valve core of the butterfly valve is controlled by a handle 1. When opening or closing the butterfly valve or adjusting the opening degree of the butterfly valve, the handle 1 is pressed down (if the handle 1 is not pressed down, the valve core is in a self-locking state and cannot rotate), and then the valve core is rotated; such butterfly valves are relatively deep, and workers cannot directly operate on the ground. It is rather troublesome and extremely inconvenient for workers to enter the pit to operate the handle 1. Moreover, when an emergency situation requires the butterfly valve to be closed immediately, it cannot be closed in time.

[0004] In summary, it is obvious that the prior art has inconveniences and defects in actual use, so it is necessary to improve it. Content of the Utility Model

[0005] Aiming at the deficiencies in the background art, the utility model provides a driving tool for a butterfly valve in a pit, which has a simple structure and does not require entering the interior of the pit. With this tool on the ground, the butterfly valve can be driven quickly and simply.

[0006] To solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A driving tool for a butterfly valve in a pit includes an operating rod and an extension rod. The extension rod is perpendicularly arranged with the operating rod. The front end of the extension rod is provided with a first card slot and a second card slot. The first card slot and the second card slot are arranged opposite to each other, and the depth of the first card slot is deeper than that of the second card slot.

[0008] Further, a driving head is provided at the front end of the extension rod. A cavity is arranged inside the driving head, making the driving head in a cylindrical shape. The first card slot and the second card slot are arranged at the front end of the driving head.

[0009] Further, the extension rod is welded at the middle position of the operating rod, and a driving head is welded at the front end of the extension rod.

[0010] Further, the operating rod includes two folding rods and an intermediate rod. The two folding rods are respectively hinged to both ends of the intermediate rod, and the extension rod is welded to the intermediate rod.

[0011] Further, the extension rod is formed by connecting multiple short rods end to end.

[0012] Further, one end of the short rod is provided with a check screw, and the other end is provided with a threaded hole. The check screw at one end of the short rod is installed in the threaded hole of another short rod.

[0013] Further, a check screw is welded at the middle position of the operating rod. The check screw of the operating rod is installed in the threaded hole of the short rod; a threaded hole is provided at the rear end of the driving head, and the check screw of the short rod is installed in the threaded hole of the driving head.

[0014] After the present utility model adopts the above technical solutions, compared with the prior art, it has the following advantages:

[0015] Insert the front end of the extension rod deep into the pit, so that the second card slot with a shallow depth is stuck on the handle side of the butterfly valve, and the first card slot with a deep depth is stuck on the opposite side of the handle. Hold the operating rod and press it down. Use the second card slot to tilt the handle downward, and the opposite side of the handle is stuck on the first card slot. Then, the operating rod can be rotated to rotate the butterfly valve, so that workers do not need to enter the pit. On the ground, this tool can be used to quickly and simply drive the butterfly valve.

[0016] The following will describe the present utility model in detail with reference to the drawings and embodiments. Description of the Drawings

[0024] As Figure 2 shown, the present utility model provides a driving tool for a butterfly valve in a pit, which includes an operating rod 2 and an extension rod 3. The extension rod 3 is perpendicularly arranged with respect to the operating rod 2. A first slot 5 and a second slot 6 are provided at the front end of the extension rod 3. The first slot 5 and the second slot 6 are arranged opposite to each other, and the depth of the first slot 5 is deeper than that of the second slot 6.

[0025] When using this tool to drive the butterfly valve, the front end of the extension rod 3 is inserted into the pit, so that the second slot 6 with a shallower depth is stuck on the side of the handle 1 of the butterfly valve, and the first slot 5 with a deeper depth is stuck on the opposite side of the handle 1. Hold the operating rod 2 and press down, tilt the handle 1 downward with the second slot 6, and the opposite side of the handle 1 is stuck on the first slot 5. Then, the operating rod 2 can be rotated to rotate the butterfly valve.

[0026] A driving head 4 is provided at the front end of the extension rod 3. A cavity is provided inside the driving head 4, so that the driving head 4 is in a cylindrical shape. The first slot 5 and the second slot 6 are arranged at the front end of the driving head 4.
