Benefits of technology

[0013] The beneficial effects of this utility model are as follows: By setting clamping rods, when the space of the main body mechanism is relatively limited or difficult to access, according to the rim diameter or spoke spacing of the handwheel on the top of the valve body, the limiting ring is rotated counterclockwise at the bottom of each clamping rod to reduce the pressure of the top of the limiting ring pressing the bottom of the base plate, thereby releasing the restriction on the horizontal position of the clamping rods. Then, in conjunction with the markings on the scale in the U-shaped limiting hole, each clamping rod is slid inward or outward to the desired position so that the slot can engage with the rim or spoke outer wall of the handwheel. According to the required height distance, a corresponding number of connecting rods are added to make the connecting rods engage with each other. The lower end of the bottom connecting rod is engaged with the inner wall of the cavity column, and the upper end of the top connecting rod is engaged with the inner wall of the bottom end of the handle. The limiting pins are inserted into the corresponding through holes for further fixation. Finally, the device is held by the hand dial. The entire assembly is lowered so that the slot locks onto the rim or outer wall of the handwheel. Multiple clamping rods clamp the handwheel horizontally. Finally, rotating the handwheel drives the extension mechanism to rotate, which in turn drives the handwheel to rotate synchronously, opening or closing the main body mechanism. This effectively avoids situations where traditional wrenches cannot operate deep well valves due to limited working space or inaccessible installation locations. It reduces the difficulty of operation and also reduces the risk of valve damage and safety accidents. By setting shims, the clamping rods can be effectively prevented from loosening by applying support force to the top block, ensuring the stability of the clamping rod position. By setting a scale, the comparison between the scale and the top block can effectively indicate the movement stroke and current position of the top block and its bottom clamping rod, improving the accuracy of personnel when adjusting the position of the clamping rod.

[0002] Valves are devices installed in pipeline systems to control fluid flow by changing the flow area or direction of the flow path. Their main functions are to regulate flow rate, cut off fluid flow, prevent backflow, or reduce pressure, thereby ensuring the safe and stable operation of the system.

[0003] Among the existing valve operating tools, traditional wrenches are often ineffective when dealing with valves in confined spaces or difficult-to-access areas due to insufficient length or limited angle. This not only increases the difficulty of the work, but may also lead to valve damage or safety accidents due to improper operation. Utility Model Content

[0004] The purpose of this utility model is to provide an extended operating handle for deep well valves, which can solve the problem that traditional wrenches are often unable to operate effectively when facing valves in confined spaces or difficult-to-access areas due to insufficient length or limited angle, and that improper operation can lead to valve damage or safety accidents.

[0005] The technical solution of this utility model is as follows: An extended operating handle for a deep well valve includes a main body mechanism and an extension mechanism disposed on the top of the main body mechanism. The extension mechanism includes a plurality of clamping rods symmetrically arranged and inserted into the outer wall of a handwheel via slots. A limit ring is threaded to the outer side of the bottom end of each clamping rod. A top block is fixedly connected to the top of each clamping rod. A base plate is movably connected to the outer side of each clamping rod through a limit hole. A hollow column is fixedly connected to the top of the base plate. A connecting rod is clamped and connected to the top of the hollow column. A handle is clamped and connected to the top of the connecting rod. A hand disc is fixedly connected to the top of the handle. Through holes are provided on the inner sides of the hollow column, the connecting rod, and the handle, and the through holes correspond one-to-one.

[0006] The main body mechanism includes a valve body, with adapter pipes fixedly connected to both sides of the valve body, and a handwheel rotatably connected to the top of the valve body.

[0007] The limiting hole has a U-shaped structure, and a clamping rod is movably connected to the inner side of the limiting hole.

[0008] A washer is movably connected to the outer side of the top end of the clamping rod, and the washer is located between the bottom plate and the top block.

[0009] A ruler is fixedly connected to the top of the base plate. Several rulers are symmetrically arranged, and each ruler is located on one side of the top block.

[0010] A reinforcing rib is fixedly connected to one side of the hollow column. Several reinforcing ribs are symmetrically arranged. A base plate is fixedly connected to the bottom of the reinforcing rib. The reinforcing rib has an inclined structure.

[0011] A socket is provided on one side of the top of the handle, and the socket extends through the inside of the handle.

[0012] The outer surface of the main body is provided with an electroplated anti-oxidation coating.

[0013] The beneficial effects of this utility model are as follows: By setting clamping rods, when the space of the main body mechanism is relatively limited or difficult to access, according to the rim diameter or spoke spacing of the handwheel on the top of the valve body, the limiting ring is rotated counterclockwise at the bottom of each clamping rod to reduce the pressure of the top of the limiting ring pressing the bottom of the base plate, thereby releasing the restriction on the horizontal position of the clamping rods. Then, in conjunction with the markings on the scale in the U-shaped limiting hole, each clamping rod is slid inward or outward to the desired position so that the slot can engage with the rim or spoke outer wall of the handwheel. According to the required height distance, a corresponding number of connecting rods are added to make the connecting rods engage with each other. The lower end of the bottom connecting rod is engaged with the inner wall of the cavity column, and the upper end of the top connecting rod is engaged with the inner wall of the bottom end of the handle. The limiting pins are inserted into the corresponding through holes for further fixation. Finally, the device is held by the hand dial. The entire assembly is lowered so that the slot locks onto the rim or outer wall of the handwheel. Multiple clamping rods clamp the handwheel horizontally. Finally, rotating the handwheel drives the extension mechanism to rotate, which in turn drives the handwheel to rotate synchronously, opening or closing the main body mechanism. This effectively avoids situations where traditional wrenches cannot operate deep well valves due to limited working space or inaccessible installation locations. It reduces the difficulty of operation and also reduces the risk of valve damage and safety accidents. By setting shims, the clamping rods can be effectively prevented from loosening by applying support force to the top block, ensuring the stability of the clamping rod position. By setting a scale, the comparison between the scale and the top block can effectively indicate the movement stroke and current position of the top block and its bottom clamping rod, improving the accuracy of personnel when adjusting the position of the clamping rod.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-4As shown, an extended operating handle for a deep well valve includes a main body mechanism 1 and an extension mechanism 2 disposed on top of the main body mechanism 1 to increase the working height, extend the working space to a wider area, and facilitate operation. The extension mechanism 2 includes several clamping rods 208 symmetrically arranged on the outer wall of the handwheel 103 and inserted into slots 209. A limit ring 211 is threaded to the outer side of the bottom end of the clamping rod 208. A top block 210 is fixedly connected to the top of the clamping rod 208. A base plate 201 is movably connected to the outer side of the clamping rod 208 through a limit hole 207. A hollow column 202 is fixedly connected to the top of the plate 201. A connecting rod 203 is clamped and connected to the top of the hollow column 202. A handle 204 is clamped and connected to the top of the connecting rod 203. A handwheel 205 is fixedly connected to the top of the handle 204. Through holes 206 are provided on the inner sides of the hollow column 202, the connecting rod 203, and the handle 204. The through holes 206 correspond one-to-one. When the space of the main body mechanism 1 is relatively limited or difficult to access, according to the rim diameter or spoke spacing of the handwheel 103 on the top of the valve body 101, the bottom of each clamping rod 208 is adjusted. Rotate the limiting ring 211 counterclockwise to reduce the pressure of the top of the limiting ring 211 pressing against the bottom of the base plate 201, thereby releasing the restriction on the horizontal position of the clamping rod 208. Then, in conjunction with the markings on the scale 4 within the U-shaped limiting hole 207, slide each clamping rod 208 inward or outward to the desired position, so that the slot 209 can engage with the rim or spoke outer wall of the handwheel 103. Add a corresponding number of connecting rods 203 according to the required height distance, so that the connecting rods 203 are engaged with each other, and then connect the bottom connecting rods 203. The lower end is inserted into the inner wall of the cavity column 202, and the upper end of the top connecting rod 203 is inserted into the inner wall of the bottom end of the handle 204. The limiting pins are inserted into the corresponding through holes 206 for further fixation. Finally, after holding the hand disc 205, the entire device is lowered so that the slot 209 is engaged with the outer wall of the rim or spoke of the handwheel 103. The handwheel 103 is clamped in the horizontal direction by multiple sets of clamping rods 208. Finally, the hand disc 205 is rotated to drive the extension mechanism 2 to rotate as a whole, driving the handwheel 103 to rotate synchronously, thus completing the opening or closing of the main body mechanism 1.

[0021] In this utility model, the main body mechanism 1 includes a valve body 101, with adapter pipes 102 fixedly connected to both sides of the valve body 101, and a handwheel 103 rotatably connected to the top of the valve body 101. The valve body 101 is opened or closed by rotating the handwheel 103.

[0022] The limiting hole 207 has a U-shaped structure, and a clamping rod 208 is movably connected to the inner side of the limiting hole 207. The spacing of the clamping rod 208 can be adjusted according to the size of the handwheel 103 to adapt to various handwheel 103 specifications and improve applicability.

[0023] A pad 3 is movably connected to the outer side of the top end of the clamping rod 208. The pad 3 is located between the base plate 201 and the top block 210. It can effectively reduce the loosening of the clamping rod 208 by applying a supporting force to the top block 210, thus ensuring the stability of the position of the clamping rod 208.

[0024] A ruler 4 is fixedly connected to the top of the base plate 201. Several rulers 4 are symmetrically arranged. Each ruler 4 is located on one side of the top block 210. By comparing the ruler 4 with the top block 210, the movement stroke and current position of the top block 210 and its bottom clamping rod 208 can be effectively indicated, improving the accuracy of personnel when adjusting the position of the clamping rod 208.

[0025] A reinforcing rib 5 is fixedly connected to one side of the cavity column 202. Several reinforcing ribs 5 are symmetrically arranged. A base plate 201 is fixedly connected to the bottom of the reinforcing rib 5. The reinforcing rib 5 has an inclined structure, which can effectively ensure the stability of the structure between the cavity column 202 and the base plate 201.

[0026] A socket 6 is provided on one side of the top of the handle 204. The socket 6 extends through the inside of the handle 204. By inserting the rod into the socket 6 and rotating the rod, the physical effort required for rotation can be effectively saved. It is also suitable for handwheels 103 with a high degree of tightness.

[0027] The outer surface of the main body 1 is coated with an electroplated anti-oxidation coating, which can effectively reduce the risk of material strength reduction caused by oxidation and corrosion, and ensure the service life of the device.

[0028] The working principle and usage process of this utility model are as follows: When the space of the main body mechanism 1 is limited or difficult to access, according to the rim diameter or spoke spacing of the handwheel 103 at the top of the valve body 101, the limiting ring 211 is rotated counterclockwise at the bottom of each clamping rod 208 to reduce the pressure of the top of the limiting ring 211 pressing against the bottom of the base plate 201, thereby releasing the restriction on the horizontal position of the clamping rod 208. Then, in conjunction with the markings on the scale 4 in the U-shaped limiting hole 207, each clamping rod 208 is slid inward or outward to the desired position, so that the slot 209 can engage with the rim or spoke outer wall of the handwheel 103. According to the required height distance, a corresponding number of connecting rods 203 are added to make the connecting rods 203 interlocked, and the bottom connecting rods 203 are then... The lower end of the connecting rod 203 is inserted into the inner wall of the cavity column 202, and the upper end of the connecting rod 203 is inserted into the inner wall of the bottom end of the handle 204. The limiting pins are then inserted into the corresponding through holes 206 for further fixation. Finally, the entire device is lowered after holding the hand disc 205, so that the slot 209 is engaged with the outer wall of the rim or spoke of the handwheel 103. The handwheel 103 is clamped in the horizontal direction by multiple sets of clamping rods 208. Finally, the hand disc 205 is rotated to drive the extension mechanism 2 to rotate as a whole, which drives the handwheel 103 to rotate synchronously, thus completing the opening or closing of the main body mechanism 1. This effectively avoids the situation where traditional wrenches cannot operate deep well valves due to limited working space or difficult-to-access installation positions. It reduces the difficulty of operation and also reduces the risk of valve damage and safety accidents.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
