Description

Technical Field

[0001] This utility model relates to the field of valves, specifically a valve auxiliary opening and closing device. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the transported medium. Based on their function, they can be classified into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow splitting, or pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to the various valves used in extremely complex automated control systems, with a wide variety of types and specifications.

[0003] In existing technology, butterfly valves mainly rely on the rotation of the internal butterfly disc to open and close the pipeline. The rotation of the butterfly disc is usually controlled by a worm gear reducer. The worm gear reducer is mainly composed of a worm wheel and a worm. Although it has self-locking properties, it also increases the number of rotations of the worm to open the butterfly valve smoothly. This means that when opening and closing the butterfly valve, it is necessary to manually rotate it many times, which is quite troublesome and requires a lot of effort. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, although worm gear reducers have self-locking properties, they also increase the number of rotations of the worm gear to open the butterfly valve smoothly. This results in the need to manually rotate the worm gear multiple times when opening and closing the butterfly valve, which is quite troublesome and requires a lot of effort. This utility model proposes a valve auxiliary opening and closing device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a valve auxiliary opening and closing device, including a butterfly valve, wherein an auxiliary mechanism is provided on the surface of the butterfly valve;

[0006] The auxiliary mechanism includes a fixed plate, the bottom of which is fixedly connected to the top of the butterfly valve. A second connecting rod is fixedly connected to one side of the fixed plate, and a first gear is rotatably connected to one side of the second connecting rod. The surface of the butterfly valve is provided with the first connecting rod, and a second gear is fixedly connected to one side of the first connecting rod. The teeth of the second gear mesh with the teeth of the first gear. A U-shaped rod is fixedly connected to one side of the first gear, and a rotating rod is rotatably connected to the surface of the U-shaped rod.

[0007] Preferably, a second magnet block is fixedly connected to the surface of the rotating rod, a first magnet block is provided on one side of the second magnet block, and one side of the first magnet block is fixedly connected to one side of the first gear.

[0008] Preferably, the surface of the rotating rod is provided with a first support block and a second support block, and one side of each of the first support block and the second support block is fixedly connected to one side of the first gear.

[0009] Preferably, a limiting groove is formed on the surface of the second connecting rod, and a T-shaped rotating block is rotatably connected to the inner cavity of the limiting groove. One side of the T-shaped rotating block is fixedly connected to one side of the first gear.

[0010] Preferably, a reinforcing block is provided on the surface of the first connecting rod, and the inner cavity of the reinforcing block is fixedly connected to the surface of the second connecting rod.

[0011] Preferably, a sleeve is slidably connected to the surface of the rotating rod, and a rubber sleeve is fixedly connected to the surface of the sleeve.

[0012] Preferably, a fixing rod is fixedly connected to the surface of the second connecting rod, and one side of the fixing rod is fixedly connected to one side of the fixing plate.

[0013] The advantages of this utility model are:

[0014] This invention utilizes a rotating rod, which, when pressed, drives a first gear via a U-shaped rod. The first gear then drives a second gear, which in turn drives a worm gear reducer in the butterfly valve via a first connecting rod. This worm gear, in turn, drives the butterfly valve disc, thus opening and closing the pipe. Because the diameter of the first gear is larger than that of the second gear, one rotation of the first gear drives the second gear and the first connecting rod to rotate multiple times, thereby allowing the butterfly valve worm to rotate multiple times as well, facilitating the opening and closing of the butterfly valve. The butterfly disc design makes the butterfly valve easier and more convenient to rotate, eliminating the need for multiple rotations. After the rotating rod drives the first gear to rotate half a turn, the rotating rod can be rotated laterally to the other side to continue pressing down on the rotating rod to drive the first gear to rotate. This eliminates the need to push the rotating rod upwards after rotating half a turn, making it more convenient and less strenuous. This design also solves the problem that while worm gear reducers have self-locking properties, they also increase the number of rotations of the worm gear to open the butterfly valve smoothly. This previously required manual rotation of multiple turns when opening and closing the butterfly valve, which was cumbersome and laborious. Attached Figure Description

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a valve auxiliary opening and closing device. (Refer to...) Figure 1-4 A valve auxiliary opening and closing device includes a butterfly valve 1. An auxiliary mechanism 2 is provided on the surface of the butterfly valve 1. The butterfly valve 1 can be used to connect to a pipeline to control the opening and closing of the water flow in the pipeline. The auxiliary mechanism 2 makes it easier and less strenuous for people to turn the butterfly valve 1.

[0024] The auxiliary mechanism 2 includes a fixed plate 202, the bottom of which is fixedly connected to the top of the butterfly valve 1. A second connecting rod 203 is fixedly connected to one side of the fixed plate 202. A first gear 204 is rotatably connected to one side of the second connecting rod 203. A first connecting rod 201 is provided on the surface of the butterfly valve 1. A second gear 205 is fixedly connected to one side of the first connecting rod 201. The teeth of the second gear 205 mesh with the teeth of the first gear 204. A U-shaped rod 206 is fixedly connected to one side of the first gear 204. A rotating rod 207 is rotatably connected to the surface of the U-shaped rod 206.

[0025] The first connecting rod 201 is fixedly connected to one side of the worm gear reducer of the butterfly valve 1, so that when the first connecting rod 201 rotates, it drives the worm gear of the butterfly valve 1 to rotate together, thereby controlling the opening and closing of the butterfly disc inside the butterfly valve 1. The fixing plate 202 can be used to connect the second connecting rod 203, and the second connecting rod 203 can be connected to the first gear 204, so that the first gear 204 can rotate on one side of the butterfly valve 1. The second gear 205 can be used to connect the first connecting rod 201 and the first gear 204, so that when the first gear 204 rotates, it drives the second gear 205 and the first connecting rod 201 to rotate together. The diameter of the first gear 204 is larger than the diameter of the second gear 205, so that one rotation of the first gear 204 can drive the second gear 205 and the first connecting rod 201 to rotate multiple times, thereby causing the worm gear of the butterfly valve 1 to rotate multiple times as well. The U-shaped rod 206 facilitates the opening and closing of the butterfly valve 1, making it easier and less strenuous to rotate the butterfly valve 1 without requiring multiple rotations. It connects the first gear 204 and the rotating rod 207, allowing the rotating rod 207 to be stably positioned on one side of the first gear 204. The long rotating rod 207 allows users to hold one side and press down, thus rotating the first gear 204. Through leverage, this makes rotating the first gear 204 easier. The rotating rod 207 can also rotate on one side of the first gear 204 via the U-shaped rod 206. After the rotating rod 207 rotates the first gear 204 half a turn, it can be rotated to the other side via the U-shaped rod 206 to repeat the downward pressing of the rotating rod 207. This eliminates the need to push the rotating rod 207 upwards after only half a turn, making it more convenient and less strenuous.

[0026] Reference Figure 2 A second magnet block 4 is fixedly connected to the surface of the rotating rod 207. A first magnet block 3 is provided on one side of the second magnet block 4. One side of the first magnet block 3 is fixedly connected to one side of the first gear 204. The first magnet block 3 is connected to one side of the first gear 204, while the second magnet block 4 is connected to the surface of the rotating rod 207. The first magnet block 3 and the second magnet block 4 can be magnetically attracted together, so that the rotating rod 207 can be stabilized on one side of the first gear 204. It is not easy for the rotating rod 207 to rotate on the surface of the U-shaped rod 206 when the rotating rod 207 is pressed. In addition, two sets of first magnet blocks 3 and second magnet blocks 4 are provided on one side of the first gear 204, so that the rotating rod 207 can also be stabilized when it rotates to the other side.

[0027] Reference Figure 2The surface of the rotating rod 207 is provided with a first support block 5 and a second support block 6. One side of the first support block 5 and the second support block 6 are fixedly connected to one side of the first gear 204. The first support block 5 and the second support block 6 are located on the upper and lower sides of the rotating rod 207, respectively, which can support and reinforce the rotating rod 207, so that the rotating rod 207 is not easily broken or damaged by the U-shaped rod 206 when pressed. In addition, two sets of first support blocks 5 and second support blocks 6 are provided on one side of the first gear 204, so that the rotating rod 207 can also be reinforced when it rotates to the other side.

[0028] Reference Figure 4 A limiting groove 7 is formed on the surface of the second connecting rod 203. A T-shaped rotating block 8 is rotatably connected to the inner cavity of the limiting groove 7. One side of the T-shaped rotating block 8 is fixedly connected to one side of the first gear 204. The limiting groove 7 can limit one side of the first gear 204 through the T-shaped rotating block 8, so that the first gear 204 rotates more stably on one side of the second connecting rod 203 and is less likely to detach from the second connecting rod 203.

[0029] Reference Figure 4 The surface of the first connecting rod 201 is provided with a reinforcing block 9. The inner cavity of the reinforcing block 9 is fixedly connected to the surface of the second connecting rod 203. The reinforcing block 9 can reinforce the connection between the first connecting rod 201 and the second connecting rod 203, so that the second connecting rod 203 and the first connecting rod 201 can reinforce each other and are not prone to shaking or breaking.

[0030] Reference Figure 2 A sleeve 10 is slidably connected to the surface of the rotating rod 207, and a rubber sleeve 11 is fixedly connected to the surface of the sleeve 10. The sleeve 10 can slide on the surface of the rotating rod 207, thereby increasing the length of the rotating rod 207 and making it easier to press and rotate the rotating rod 207. At the same time, the length of the rotating rod 207 can be shortened when not in use. The rubber sleeve 11 makes the palm more comfortable when people press the rotating rod 207.

[0031] Reference Figure 4 A fixing rod 12 is fixedly connected to the surface of the second connecting rod 203. One side of the fixing rod 12 is fixedly connected to one side of the fixing plate 202. The fixing rod 12 can reinforce the connection between the fixing plate 202 and the second connecting rod 203, making the second connecting rod 203 more firmly connected to one side of the fixing plate 202.

[0032] Working Principle: When using this device, first press and rotate the rotating rod 207. The rotating rod 207 will drive the first gear 204 to rotate via the U-shaped rod 206. The first gear 204 will then rotate on one side of the second connecting rod 203. Simultaneously, the first gear 204 will drive the second gear 205 to rotate. At the same time, the second gear 205 will drive the worm in the worm gear reducer of the butterfly valve 1 to rotate via the first connecting rod 201, thereby driving the butterfly disc of the butterfly valve 1 to rotate, thus opening and closing the pipeline. Since the diameter of the first gear 204 is larger than the diameter of the second gear 205, one rotation of the first gear 204 will drive the second gear 205 and the first connecting rod 201 to rotate multiple times. This allows the worm gear of butterfly valve 1 to rotate multiple times, facilitating the opening and closing of the butterfly valve 1's disc. This makes rotating the disc of butterfly valve 1 more effortless and convenient, eliminating the need for multiple rotations. After the rotating rod 207 drives the first gear 204 to rotate half a turn, the rotating rod 207 can be rotated laterally to the other side, allowing further downward pressure on the rotating rod 207 to drive the first gear 204 to rotate. This eliminates the need to push the rotating rod 207 upwards after only half a turn, making it more convenient and effortless. This solves the problem that while worm gear reducers have self-locking properties, they also increase the number of worm gear rotations required to open butterfly valve 1 smoothly. This previously resulted in the need for manual rotation multiple times when opening and closing butterfly valve 1, which was cumbersome and laborious.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
