Description

Technical Field

[0001] The invention discloses a tool for quickly closing and opening a water supply valve, which is used for quickly closing and opening a water supply valve and belongs to the technical field of tools for quickly closing and opening a water supply valve. Background Art

[0002] Water supply valves play a vital role in residential, commercial, industrial and municipal water supply systems. They are devices used to control the flow of water in pipe systems. Their main uses include:

[0003] Opening and closing the flow of water: Valves can be fully opened or closed to stop or allow water to flow through. Adjusting the flow rate: Certain types of valves, such as regulating valves, can adjust the flow of water to suit different needs. Preventing backflow: Check valves or check valves can prevent water from flowing backwards in the piping system, protecting water quality and equipment. Zoning control: In large water networks or buildings, valves are used to divide the system into different areas for maintenance, modification or emergency shutdown. Pressure reduction: Pressure reducing valves are used to control the pressure in the piping system to prevent damage caused by excessive pressure. Emergency shut-off: In an emergency, such as a pipe rupture, the valve can be quickly closed to avoid water loss and further damage.

[0004] In the prior art, operators usually open or close the water supply valve by holding the valve disc (or handwheel, including the inner and outer rings, and the rod connecting the inner and outer rings). This method is not only laborious but also cannot quickly open or close the water supply valve. Therefore, operators usually use a wrench to assist the switch. Although this can save labor and increase the speed of opening or closing, it still has the following technical problems:

[0005] 1. When opening and closing the water supply valve, the force point of the wrench is on one position of the disc, which can easily cause the disc (or handwheel) to wear easily;

[0006] 2. The wrench is easily restricted by narrow space, which makes operation difficult. Utility Model Content

[0007] The purpose of the utility model is to provide a tool for quickly closing and opening a water supply valve, so as to solve the problem that when opening and closing the water supply valve, the force point of the wrench is on one position of the disc, which easily causes the disc (or handwheel) to wear.

[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0009] A tool for quickly closing and opening a water supply valve comprises a fixing member matched with an outer disc of a disc and a connecting rod, and a rotating member arranged on the fixing member;

[0010] The fixing member comprises an annular plate, and a clamping member is arranged on the annular plate at the connection between each outer disc on the clamping disc and the connecting rod.

[0011] Furthermore, the clamping member includes a first clamping member provided on the annular plate and used to be placed on the outer side of the outer disc, and a second clamping member used to be placed on the inner side of the outer disc and on both sides of the connecting rod.

[0012] Furthermore, the annular plate is provided with a plurality of sliding grooves corresponding to the connecting rods;

[0013] The clamping member also includes a connecting block connecting the first clamping member and the second clamping member, a screw rod provided on the connecting block and slidingly matched with the slide groove, and a nut matched with the screw thread to fix the clamping member on the annular plate.

[0014] Furthermore, a clamping groove is provided on the opposite side of the sliding groove, and a clamping block that matches the clamping groove is provided on the screw rod.

[0015] Furthermore, a rotating shaft is provided at the center of the annular plate, a turntable is rotatably provided on the rotating shaft, and a diameter-changing sliding groove cooperating with the screw is provided on the turntable.

[0016] Furthermore, a rotating handle is provided on the rotating disk.

[0017] Furthermore, a plurality of polygonal slots are provided on the edge of the annular plate along the circumference direction of the annular plate; or / and

[0018] A plurality of thread grooves are provided on the edge of the annular plate along the circumference direction of the annular plate;

[0019] The rotating member includes a rod body, one end of which is provided with a plug that matches the polygonal slot; or

[0020] The rotating member comprises a rod body, one end of which is provided with a thread head matched with the thread groove.

[0021] Furthermore, the polygonal slots and the threaded grooves are arranged at equal intervals on the outer edge of the annular plate;

[0022] The rod body is a telescopic rod.

[0023] Furthermore, the first clamp and the second clamp are cylindrical structures, and a rubber protective layer is provided on the outer surface.

[0024] Compared with the prior art, the advantages of the present invention are:

[0025] First, the utility model provides a clamping member on the annular plate to cooperate with the disc. The clamping member clamps the connection between the outer disc and the connecting rod on the disc, which can more evenly distribute the force on the outer disc and the connecting rod, reducing local wear caused by concentrated force. In addition, with the cooperation of the rotating member, the operator can easily and quickly rotate the disc of the water supply valve with less effort, thereby realizing rapid opening and closing of the water supply valve, thereby improving the working effect.

[0026] Second, the clamping member of the present invention includes a first clamping member and a second clamping member, which can fully clamp the outer disc and the connecting rod from both the inside and outside of the disc, ensuring the stability and reliability of the tool during operation, and also facilitating the forward opening and reverse closing of the water supply valve;

[0027] 3. The utility model provides a slide groove on the annular plate and cooperates with the screw in the clamping piece, so that the operator can adjust the position of the clamping piece and the connection between the outer disc and the connecting rod according to the size and position of the connecting rod or the diameter of the outer disc, so that the tool can adapt to water supply valves of different specifications;

[0028] Fourth, the utility model provides a clamping groove in the chute, and a clamping block that matches the clamping groove is provided on the screw to prevent the clamping member from separating from the annular plate, and also ensures that the clamping member does not rotate when it moves in a directional manner in the chute;

[0029] 5. The utility model provides a rotating shaft on the annular plate, and a rotating disk with a variable diameter chute on the rotating shaft, so that the positions of multiple screws in the corresponding chute can be adjusted synchronously by rotating the rotating disk. When the position of the screw changes, the first clamping member and the second clamping member will also change position. The nut is then fixed on the screw to prevent the rotating disk from rotating under force. At the same time, it can be quickly adapted to the diameter of different water supply valve discs and the spacing between the screws after synchronous adjustment.

[0030] 6. The purpose of setting the turning handle in this utility model is to facilitate the easy rotation of the turntable;

[0031] 7. The utility model provides multiple polygonal slots and / or threaded heads on the outer diameter side of the annular plate, making it easy to select a suitable rotating part with a plug and / or threaded head to suit different scenarios;

[0032] 8. The present invention defines the rod as a telescopic rod. The operator can adjust the length of the rod as needed to accommodate valves of different sizes and different operating spaces.

[0033] 9. The purpose of limiting the first clamp and the second clamp to a cylindrical structure in the present invention is to provide a larger contact area and to avoid sharp corners that may rub against the disc. The provision of a rubber protective layer can reduce direct contact between the metal clamp and the valve disc, reduce wear on the disc during operation, and extend the service life of the water supply valve.

[0050] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0051] Example 1

[0052] In order to solve the problem that when opening and closing the water supply valve, the force point of the wrench is on one position of the disc, which easily causes the disc (or hand wheel) to wear. Figure 1-8 As shown, a tool for quickly closing and opening water supply valves is provided, including a fixing member 1 that cooperates with the outer disk 24 of the disk 23 and the connecting rod 25, and a rotating member 2 set on the fixing member 1; the fixing member 1 includes an annular plate 3, and a clamping member 4 set on the annular plate 3 to clamp the connection between each outer disk on the disk and the connecting rod.

[0053] In practice, when the water supply valve needs to be opened or closed, the clamping members 4 on the annular plate 3 are respectively clamped at the connection points between the outer discs on the disc and the connecting rod. After clamping, the annular plate is rotated forward or reversely by the rotating member to drive the disc to rotate, thereby opening or closing the water supply valve. This embodiment provides clamping members on the annular plate to cooperate with the disc. By clamping the multiple connection points between the outer discs on the disc and the connecting rod, the clamping members can more evenly distribute force on the outer discs and the connecting rod, reducing local wear caused by concentrated force. Moreover, with the cooperation of the rotating member, the operator can easily and quickly rotate the disc of the water supply valve with less effort, achieving rapid opening and closing of the water supply valve, thereby improving working efficiency.

[0054] Example 2

[0055] On the basis of Example 1, Figure 3 As shown, the clamping member 4 comprises a first clamping member 5, mounted on the annular plate 3 and positioned on the outside of the outer disc, and a second clamping member 6, positioned on the inside of the outer disc and on either side of the connecting rod. In practice, the first clamping member 5 is positioned on the outside of the outer disc, while the two second clamping members are positioned on the inside of the outer disc, one on each side of the connecting rod. The combination of the first and second clamping members allows the clamping member to fully grip the outer disc and the connecting rod from both inside and outside, ensuring stability and reliability during operation. This also facilitates forward opening and reverse closing of the water supply valve.

[0056] Example 3

[0057] In accordance with Example 2, the annular plate 3 is provided with a plurality of slots 7 corresponding to the connecting rods. The clamping member 4 further includes a connecting block 8 connecting the first clamping member 5 and the second clamping member 6, a screw 9 disposed on the connecting block 8 and slidably engaged with the slots 7, and a nut 10 threadedly engaged with the screw 9 to secure the clamping member 4 to the annular plate 4. In practice, since discs vary in size, when clamping a different disc, the nut is first rotated to allow the clamping member to slide within the slots 7. The screw is then slid within the slots according to the disc size. Once the screw is moved to a desired position, the clamping member is secured to the annular plate with the nut. Once all clamping member adjustments are complete, the clamping member can be engaged with the disc to open and close the water supply valve. The slots provided on the annular plate in this embodiment, which engage with the screws in the clamping member, facilitate adjustment of the clamping member's position to the connection between the outer disc and the connecting rod according to the size and position of the connecting rod or the diameter of the outer disc, enabling the tool to accommodate water supply valves of varying sizes.

[0058] Example 4

[0059] Based on Example 3, a clamping groove 11 is provided on the opposite side of the chute 7, and a clamping block 12 is provided on the screw 9 to cooperate with the clamping groove 11. The clamping groove is provided in the chute, and the clamping block is provided on the screw to cooperate with the clamping groove to prevent the clamping member from detaching from the annular plate and to ensure that the clamping member does not rotate during directional movement in the chute.

[0060] Example 5

[0061] On the basis of Example 4, a rotating shaft 13 is provided at the center of the annular plate 3, and a rotating disk 14 is rotatably provided on the rotating shaft 13. The rotating disk 14 is provided with a variable diameter chute 15 that cooperates with the screw 9. By providing the rotating shaft on the annular plate and the rotating disk with the variable diameter chute on the rotating shaft, it is convenient to synchronously adjust the positions of multiple screws in the corresponding chute by rotating the rotating disk. The clamping block slides in the clamping slot. When the position of the screw changes, the first clamping member and the second clamping member also change position. Then, a nut is fixed to the screw, and the nut presses the rotating disk against the annular plate to prevent the rotating disk from rotating under force. At the same time, it is convenient to quickly adapt to the diameter of different water supply valve discs and the spacing between the screws after synchronous adjustment.

[0062] Example 6

[0063] On the basis of embodiment 5, a handle 16 is provided on the turntable 14. The purpose of providing the handle is to facilitate easy rotation of the turntable. The handle 16 can be as follows Figure 1 It is shown as being arranged on an annular plate, and can also be arranged on the outer edge of the turntable as required.

[0064] Example 7

[0065] On the basis of Example 6, a plurality of polygonal slots 17 are provided on the edge of the annular plate 3 along the circumference direction of the annular plate 3; or / and a plurality of thread grooves 18 are provided on the edge of the annular plate 3 along the circumference direction of the annular plate 3;

[0066] The rotating member 2 includes a rod body 19 , one end of which is provided with a plug 20 that matches the polygonal slot 17 ; or the rotating member 2 includes a rod body 19 , one end of which is provided with a thread head 21 that matches the thread groove 18 .

[0067] In practice, a rotating member with a plug 20 can be selected separately to cooperate with each polygonal slot 17. When rotating the annular plate, due to the installation position of the disc, one side may not be able to accommodate the rotating member. In this case, the rotating member can be inserted into different polygonal slots 17 during the rotation process to achieve continuous rotation. One or more rotating members with threaded heads 21 can be selected separately to be fixed to any one or more threaded grooves 18 for the operator to operate to rotate the annular plate. Or, a rotating member with a plug 20 and a rotating member with a threaded head 21 can be used together. In this embodiment, multiple polygonal slots and / or threaded heads are provided on the outer diameter side of the annular plate, making it easy to select a suitable rotating member with a plug and / or threaded head to suit different scenarios.

[0068] Example 8

[0069] Based on Example 7, the polygonal slots 17 and the threaded grooves 18 are evenly spaced on the outer edge of the annular plate 3 for ease of operation. The rod 19 is a telescopic rod. By defining the rod as a telescopic rod, the operator can adjust the rod length as needed to accommodate valves of different sizes and different operating spaces.

[0070] Example 9

[0071] Based on Example 8, the first and second clamps 5 and 6 are cylindrical in structure, and their outer surfaces are covered with a rubber protective layer 22. The purpose of limiting the first and second clamps to a cylindrical structure is to provide a larger contact area and to avoid sharp corners that may easily rub against the disc. The provision of a rubber protective layer can reduce direct contact between the metal clamps and the valve disc, reducing wear on the disc during operation and extending the service life of the water supply valve.
