Abstract

This invention discloses an energy-saving, drip-proof quick-connect valve, relating to the field of drip-proof valve technology. It includes a valve and a pipe, with the pipe inserted into the bottom of the valve. An drip-proof assembly is installed inside the valve, comprising a lower ring fixedly connected to the bottom of the valve's inner wall. Four springs are fixedly connected in a ring array on the top surface of the lower ring, and each of the four springs has a connecting block fixedly connected to its top. A pressure plate tightly fits against the upper ring, and the sealing gasket at the bottom of the pressure plate tightly engages with the sealing groove at the top of the upper ring, forming a double-seal structure. This effectively prevents fluid from dripping from the bottom of the valve to the outside. Furthermore, the pressure plate is pulled by the springs, ensuring that it maintains a seal on the bottom of the valve even without external force, thus achieving automatic sealing of the valve outlet. Compared to existing seals made of rubber or plastic, this double-seal structure offers greater wear resistance and drip-proof advantages.

Description

Technical Field

[0001] This invention relates to the field of anti-drip valve technology, specifically to an energy-saving anti-drip quick-connect valve. Background Technology

[0002] A valve is a mechanical device used in fluid transport systems to control the flow, pressure, and direction of fluids.

[0003] Valve seals are typically made of polymer materials such as rubber and plastic. However, these materials age during long-term use of existing valves, and the valve seals are constantly eroded by the fluid flowing inside the valve, accelerating their wear. As the seals wear out, they can no longer fit tightly against the valve's sealing surface, causing them to lose their sealing effect and resulting in leakage.

[0004] Drips cause a continuous loss of fluid delivered by the valve, resulting in wasted resources and deviations in the flow rate of the fluid delivered by the valve, making it impossible for the valve to accurately control the flow of the fluid.

[0005] To address this, an energy-saving, drip-proof quick-connect valve is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide an energy-saving, drip-proof quick-connect valve to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving, leak-proof quick-connect valve, comprising a valve and a pipe, the pipe being inserted into the bottom of the valve, and an leak-proof assembly being provided inside the valve. The leak-proof assembly includes a lower ring, which is fixedly connected to the bottom of the inner wall of the valve. Four springs are fixedly connected in a ring array on the top surface of the lower ring. Each of the four springs has a connecting block fixedly connected to its top. A central tube is fixedly connected to all four connecting blocks. Four support plates are fixedly connected to the top of the central tube. A pressure plate is fixedly connected to the top of all four support plates. An upper ring is fixedly connected to the inner wall of the valve. A top column is fixedly connected to the top surface of the pressure plate. An upper truncated cone is fixedly connected to the top of the top column. A lower truncated cone is slidably connected to the top column. The cross-sectional shape of the upper and lower truncated cones is set as an isosceles trapezoid, and the shape and size of the upper and lower truncated cones are exactly the same, but the upper and lower truncated cones face opposite directions. Two support rods are symmetrically fixedly connected to the inner wall of the valve. A sliding column is slidably connected to the end of each support rod near the upper truncated cone. A slider is fixedly connected to the end of each sliding column near the upper truncated cone. A spring is fitted on each of the two sliding columns.

[0008] Furthermore, the valve is equipped with a quick-connect assembly, which includes four guide grooves arranged in a circular array on the side wall of the valve. Each of the four guide grooves has a sliding plate slidably connected inside it. Each of the four sliding plates has a toothed plate fixedly connected to one end outside the valve. The outer wall of the valve has four support blocks fixedly connected in a circular array. Each of the four support blocks has a rotating shaft rotatably connected to one end away from the valve. Each of the four rotating shafts has a gear fixedly connected to it. Each of the four gears has a connecting rod fixedly connected to one side away from the rotating shaft. Each of the four connecting rods has an arc-shaped rubber block fixedly connected to its bottom end.

[0009] Furthermore, the pipelines and valves are connected and adapted.

[0010] Furthermore, the two ends of the second spring are fixedly connected to the support rod and the slider, respectively. The bottom of the middle tube is set as a disc shape that spreads horizontally in all directions. The bottom end of the middle tube is slidably connected to the inside of the valve. The inner wall of the top end of the middle tube is set as an inwardly inclined surface.

[0011] Furthermore, the middle tube and the lower ring are slidably connected, and the two adjacent support plates do not contact each other, that is, there is a gap between the two adjacent support plates, which is used for the flow of fluid inside the valve.

[0012] Furthermore, the side of the slider near the upper truncated cone is set as an inclined surface, a downward-facing sealing gasket is provided at the bottom edge of the pressure plate, and a sealing groove is opened at the top of the upper ring corresponding to the sealing gasket.

[0013] Furthermore, guide grooves extend from both ends of the four slide plates, and the end of the slide plate located inside the valve is fixedly connected to the connecting block.

[0014] Furthermore, the toothed plate meshes with the gear, and the number of teeth on the toothed plate is half the number of teeth on the gear. The inner surface of the arc-shaped rubber block is provided with anti-slip texture.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The pressure plate and the upper ring fit tightly together, and the sealing gasket at the bottom of the pressure plate and the sealing groove at the top of the upper ring fit tightly together to form a double sealing structure. This effectively prevents fluid from dripping from the bottom of the valve to the outside. Furthermore, the bottom of the pressure plate is pulled by a spring, so that the pressure plate always maintains a seal on the bottom of the valve when there is no external force, thereby realizing the function of automatically sealing the valve outlet. Compared with existing seals made of rubber, plastic and other materials, the double sealing structure has the advantages of being more wear-resistant and leak-proof.

[0017] The annular structure composed of four arc-shaped rubber blocks squeezes the bottom of the valve and the pipeline connection to form a tight connection. The whole operation process is simple and quick. Compared with the existing connection operations such as screwing in threads or tightening bolts, it shortens the connection time between the valve and the pipeline, improves work efficiency and optimizes the operation process.

[0018] By pressing the bottom of the valve-pipe connection with four arc-shaped rubber blocks, the friction at the connection can be effectively increased, preventing relative sliding between the valve and the pipe. This enhances the stability of the valve-pipe connection and ensures that the valve-pipe connection can operate safely and stably in various complex working environments.

[0019] Four arc-shaped rubber blocks form a ring-shaped compression at the bottom of the valve-pipe connection, creating a sealing barrier at the bottom of the connection. The arc-shaped rubber blocks fit tightly against the connection, preventing fluid from leaking out and significantly improving the sealing performance of the valve-pipe connection, effectively preventing fluid leakage.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0033] The embodiments provided by this invention:

[0034] Example 1: Please refer to Figures 1 to 6 As shown, an energy-saving, drip-proof quick-connect valve includes a valve 11 and a pipe 12. The pipe 12 is inserted into the bottom of the valve 11, and the pipe 12 is connected and adapted to the valve 11.

[0035] Wherein: Valve 11 is set as an existing manual gate valve. The manual gate valve includes a valve body, handwheel, valve stem and gate, and valve seat. Specifically: the valve body and handwheel are shown in the attached drawings. The handwheel is connected to the top of the valve body. The valve stem, gate and valve seat are all existing known structures and are not shown in detail in the attached drawings.

[0036] The existing manual gate valve controls fluid flow and stops by operating a handwheel. When valve 11 needs to be opened, the operator rotates the handwheel, the valve stem rises, and the gate is lifted from the valve seat, gradually opening the fluid passage. At this time, the fluid can pass through valve 11. Conversely, when valve 11 needs to be closed, the operator rotates the handwheel in the opposite direction, the valve stem descends, and the gate gradually falls to fit tightly against the valve seat, thereby blocking the fluid passage and closing valve 11.

[0037] The main design feature of this invention lies in the anti-drip component installed inside the valve 11, such as... Figure 1-8 As shown.

[0038] The valve 11 is equipped with an anti-drip assembly, which includes a lower ring 21. The lower ring 21 is fixedly connected to the bottom of the inner wall of the valve 11. Four springs 22 are fixedly connected in a ring array on the top surface of the lower ring 21. Each of the four springs 22 is fixedly connected to a connecting block 23. A central tube 24 is fixedly connected to the four connecting blocks 23. Four support plates 25 are fixedly connected to the top of the central tube 24. A pressure plate 26 is fixedly connected to the top of the four support plates 25. An upper ring 27 is fixedly connected to the inner wall of the valve 11. The top surface of the pressure plate 26 is fixedly connected to... There is a top column 28, and an upper truncated cone 29 is fixedly connected to the top of the top column 28. A lower truncated cone 210 is slidably connected to the outer surface of the top column 28. Two support rods 211 are symmetrically fixedly connected to the inner wall of the valve 11. A horizontal sliding column 212 is slidably connected to the end of each support rod 211 near the upper truncated cone 29. A slider 213 is fixedly connected to the end of each slider 212 near the upper truncated cone 29. A spring 214 is sleeved on each of the two sliding columns 212. The two ends of the spring 214 are fixedly connected to the support rod 211 and the slider 213, respectively.

[0039] Where: Reference Figure 3 As shown, the bottom of the middle tube 24 is configured as a disc shape that spreads horizontally in all directions. The disc-shaped structure at the bottom of the middle tube 24 is slidably connected to the inner wall of the valve 11. The inner wall at the top of the middle tube 24 is configured as an inwardly inclined surface. The middle tube 24 is slidably connected to the lower ring 21.

[0040] Where: Reference Figure 3 , Figure 6 As shown, the two adjacent support plates 25 do not contact each other, that is, there is a gap between the two adjacent support plates 25. This gap is used for the flow of fluid inside the valve 11. This gap is referred to as the water channel below.

[0041] Where: Reference Figure 4 As shown, the cross-sectional shape of the upper frustum 29 and the lower frustum 210 is set as an isosceles trapezoid, and the shape and size of the upper frustum 29 and the lower frustum 210 are exactly the same, but the upper frustum 29 and the lower frustum 210 face opposite directions.

[0042] Where: Reference Figure 4 As shown, the cross-sectional shape of slider 213 is a right trapezoid. The hypotenuse of slider 213 is on the side of the top post 28, and the side closest to the upper truncated cone 29 is the long base of the right trapezoid.

[0043] Where: Reference Figure 3 , Figure 4 As shown, a downward-facing sealing gasket is provided at the bottom edge of the pressure plate 26, and a sealing groove is provided at the top of the upper ring 27 at the position corresponding to the sealing gasket.

[0044] When using the anti-drip assembly, there are two usage stages. The first usage stage is when the valve 11 is not connected to the connecting pipe 12. At this time, the spring 22 does not produce elastic deformation, the lower surface of the pressure plate 26 is in contact with the upper surface of the upper ring 27, the four support plates 25 are located below the upper ring 27, and the upper truncated cone 29 is located below the slider 213.

[0045] At this time, the sealing gasket at the bottom of the pressure plate 26 is embedded in the sealing groove at the top of the upper ring 27. The top of the pressure plate 26 is subjected to downward pressure by the fluid inside the valve 11, and the bottom of the pressure plate 26 is subjected to downward pressure by the four springs 22, so that the pressure plate 26 and the upper ring 27 are tightly fitted. As a result, the inside of the valve 11 is divided into two independent areas by the upper ring 27 and the pressure plate 26, and the fluid inside the valve 11 located at the top of the pressure plate 26 cannot flow to the bottom of the pressure plate 26.

[0046] The second stage of use is during the process of pipe 12 being inserted into the bottom of valve 11. At this time, pipe 12 moves upward inside valve 11. During the upward movement of pipe 12, pipe 12 abuts against the middle pipe 24 and pushes the middle pipe 24 upward. During the upward movement of middle pipe 24, the middle pipe 24 elastically stretches the four springs 22 through four connecting blocks 23, causing the four support plates 25 to gradually move upward above the upper ring 27. The pressure plate 26 also moves upward and contacts the upper ring 27 to form a seal. At this time, the inside of valve 11 is connected to the middle pipe 24 and the inside of pipe 12 through the water passage between the four support plates 25. Thus, the fluid inside valve 11 can enter the inside of middle pipe 24 through the water passage and flow into the inside of pipe 12 through the middle pipe 24.

[0047] During the upward movement of the central tube 24, the central tube 24 drives the pressure plate 26 to move upward synchronously through the four support plates 25. Consequently, the pressure plate 26, the top column 28, the upper truncated cone 29, and the lower truncated cone 210 move upward synchronously. As the upper truncated cone 29 moves upward, its inclined surface abuts against the inclined surfaces of the sliders 213 on both sides, causing the sliders 213 to move towards the support rod 211. With the movement of the sliders 213, the sliders 213 push the sliding column 212 to slide away from the upper truncated cone 29 at the bottom of the support rod 211. Simultaneously, the second spring 214 is compressed by the movement of the sliders 213, resulting in elastic compression. When the upper truncated cone 29 moves upward until its inclined surface no longer abuts against the sliders 213, the upper truncated cone 29 no longer applies pressure to the second spring 214 through the sliders 213, and the second spring 214 then elastically extends. When the spring 214 pushes the slider 213 and the sliding column 212 to move towards the upper truncated cone 29, until the top surface of the slider 213 is in contact with the bottom surface of the upper truncated cone 29, the pipe 12 no longer moves upward, and the slider 213 is located in the gap between the upper truncated cone 29 and the lower truncated cone 210. At this time, the upper truncated cone 29 and the slider 213 form a hook relationship. Specifically, the slider 213 can restrict the upper truncated cone 29 from moving downward, that is, the elastic contraction of the spring 22 cannot pull the middle tube 24 downward, so that the position of the leakage groove between the four support plates 25 is fixed, ensuring that when the fluid inside the valve 11 flows into the pipe 12, the position of the middle tube 24 and the flow groove between the four support plates 25 will not change, that is, the relationship between the valve 11 and the pipe 12 through the middle tube 24 is fixed.

[0048] During the operation of the above anti-drip components, the pressure plate 26 and the upper ring 27 are tightly fitted together, and the sealing gasket at the bottom of the pressure plate 26 and the sealing groove at the top of the upper ring 27 are tightly matched to form a double sealing structure, which can effectively prevent fluid from dripping from the bottom of the valve 11 to the outside. Furthermore, the bottom of the pressure plate 26 is pulled by the spring 22, so that the pressure plate 26 always maintains the sealing of the bottom of the valve 11 when there is no external force, thereby realizing the function of automatically sealing the outlet of the valve 11. Compared with existing rubber, plastic and other materials for sealing, the double sealing structure has the advantages of wear resistance and anti-drip.

[0049] When it is necessary to disconnect the connection between valve 11 and pipe 12, pipe 12 is pushed upwards, causing it to move upwards inside valve 11. At this time, pressure plate 26 moves upwards, simultaneously moving top column 28, upper frustum 29, and lower frustum 210 upwards. As lower frustum 210 moves upwards, its top edge contacts slider 213, pushing slider 213 away from lower frustum 210 and causing spring 214 to be elastically compressed. As lower frustum 210 continues to move upwards... When the inclined surface of the lower frustum 210 contacts the slider 213, the slider 213 is pushed to move towards the lower frustum 210 under the elastic extension of the spring 214. Due to the inclined surface of the lower frustum 210, the slider 213 pushes the lower frustum 210 upward on the top post 28 as it moves towards the lower frustum 210. The slider 213 eventually moves below the lower frustum 210, at which point it no longer pushes the pipe 12 upward and needs to pull it down. As the pipe 12 moves downward, the spring 214... Under the elastic contraction of spring 22, spring 22 pulls the middle tube 24 downward through connecting block 23, and the middle tube 24 drives the pressure plate 26 to move downward synchronously through support plate 25. At this time, the top column 28 and the upper truncated cone 29 move downward synchronously. Meanwhile, the lower truncated cone 210 is pressed inward and pushed upward by the sliders 213 on both sides, so that the two adjacent surfaces of the lower truncated cone 210 and the upper truncated cone 29 are tightly attached, and the lower truncated cone 210 can no longer slide upward along the top column 28. As the top column 28 and the upper truncated cone 29 move downward, the sliders... 213 is pressed by the inclined surface of the lower truncated cone 210 and slides towards the support rod 211. At the same time, the second spring 214 is elastically compressed. When the upper truncated cone 29 moves down to contact the slider 213, since the adjacent surfaces of the upper truncated cone 29 and the lower truncated cone 210 are in contact, the slider 213 cannot be inserted into the gap between the upper truncated cone 29 and the lower truncated cone 210. At this time, the slider 213 will turn and continue to slide along the inclined surface of the upper truncated cone 29 until the upper truncated cone 29 moves down to no longer contact the slider 213, and the second spring 214 is fully elastically extended.

[0050] At this point, the pipe 12 can be directly removed from the bottom of the valve 11, and the anti-drip component returns to the first stage of use as described above. Specifically, the pressure plate 26 seals the bottom of the valve 11 to prevent the valve 11 from leaking when it is not connected to the pipe 12.

[0051] Example 2: During the use of valve 11, it is often necessary to frequently replace or connect different pipelines 12. Traditional valves 11, such as gate valves and globe valves, often require multiple complex steps and specific auxiliary tools when connecting to pipelines, such as using flanges with bolts. The whole process is cumbersome and time-consuming, which is not conducive to the need for valve 11 to quickly connect to pipelines.

[0052] Please see Figures 1 to 8As shown, to solve the aforementioned problems, a quick-connection assembly is provided on the valve 11. The quick-connection assembly includes four guide grooves 31, which are equidistantly arranged in a circular array on the side wall of the valve 11. Each of the four guide grooves 31 has a sliding plate 32 slidably connected inside it. Both ends of the four sliding plates 32 extend out of the guide grooves 31. The end of the sliding plate 32 inside the valve 11 is fixedly connected to the connecting block 23. The end of each of the four sliding plates 32 outside the valve 11 is fixedly connected to a vertical toothed plate 33. The outer wall of the valve 11 has four support blocks 34 equidistantly fixedly arranged in a circular array. The end of each of the four support blocks 34 away from the valve 11 is rotatably connected to a rotating shaft 35. Each of the four rotating shafts 35 is fixedly connected to a gear 36, which meshes with the toothed plate 33. Each of the four gears 36 is fixedly connected to a connecting rod 37 on the side away from the rotating shaft 35. Each of the four connecting rods 37 is fixedly connected to an arc-shaped rubber block 38 at its bottom end.

[0053] Wherein: the toothed plate 33 meshes with the gear 36, and the number of teeth of the toothed plate 33 is half the number of teeth of the gear 36. Specifically: when the toothed plate 33 moves to the top and meshes with the gear 36, the connecting rod 37 rotates to a horizontal state; when the toothed plate 33 moves to the bottom and meshes with the gear 36, the connecting rod 37 rotates to a vertical state.

[0054] Where: Reference Figure 8 As shown, the surface of the arc-shaped rubber block 38 facing the pipe 12 is provided with anti-slip texture. The four arc-shaped rubber blocks 38 are divided into four equal parts in a ring. Specifically, when the four arc-shaped rubber blocks 38 are brought together, the two sides of the four arc-shaped rubber blocks 38 abut against and fit against the adjacent arc-shaped rubber blocks 38.

[0055] When the quick-connect component is not in use, it is in the first stage of operation of the above-mentioned anti-drip component. Specifically, the pipe 12 is not inserted into the valve 11, the spring 22 is not elastically stretched, the pressure plate 26 and the upper ring 27 are tightly fitted, the connecting block 23 drives the sliding plate 32 to the bottom position of the guide groove 31, at this time the meshing part of the toothed plate 33 and the gear 36 is the top of the toothed plate 33, the connecting rod 37 is in a horizontal state, and the four arc-shaped rubber blocks 38 open in four directions.

[0056] When the quick-connect component is in use, it is in the second stage of operation of the aforementioned anti-drip component. Specifically, pipe 12 is inserted into the bottom of valve 11 and pushes the middle pipe 24 upward. The middle pipe 24 drives the connecting block 23 upward. At this time, the connecting block 23 drives the slide plate 32 to move upward synchronously, so that the slide plate 32 slides upward inside the guide groove 31. At this time, the slide plate 32 will drive the toothed plate 33 to move upward synchronously. As the toothed plate 33 moves upward, the gear 36 meshing with the toothed plate 33 rotates. As gear 36 rotates, it drives connecting rod 37 to rotate synchronously toward pipe 12. When the bottom of toothed plate 33 meshes with gear 36, connecting rod 37 rotates to a vertical position, that is, connecting rod 37 rotates to contact the bottom of the outer wall of valve 11. At the same time, arc-shaped rubber block 38 contacts the outer wall of pipe 12. Specifically, arc-shaped rubber block 38 contacts and adheres to the bottom end of the connection between valve 11 and pipe 12. Arc-shaped rubber block 38 undergoes elastic deformation, applying pressure to the bottom end of the connection between valve 11 and pipe 12.

[0057] At this time, the four arc-shaped rubber blocks 38 are wrapped around and attached to the bottom of the connection between valve 11 and pipe 12. Combined with the operation of the anti-drip assembly mentioned above, as the slider 213 in the anti-drip assembly extends into the bottom of the upper truncated cone 29, the relationship between the flow of fluid between valve 11 and pipe 12 through the middle pipe 24 is fixed, that is, the position of the middle pipe 24 and the connecting block 23 is fixed. Specifically, the position of the toothed plate 33 is fixed. At this time, the part where the toothed plate 33 meshes with the gear 36 is the bottom of the toothed plate 33 and this state is fixed. That is, the state of the four arc-shaped rubber blocks 38 pressing the bottom of the connection between valve 11 and pipe 12 is fixed.

[0058] Four arc-shaped rubber blocks 38 form a ring to compress the bottom of the connection between valve 11 and pipe 12, forming a tight connection. The entire operation is simple and quick. Compared with existing connection operations such as screwing in threads or tightening bolts, it shortens the connection time between valve 11 and pipe 12, improves work efficiency, and optimizes the operation process.

[0059] By pressing the bottom of the connection between valve 11 and pipe 12 with four arc-shaped rubber blocks 38, the friction at the connection can be effectively increased, preventing relative sliding between valve 11 and pipe 12. This enhances the stability of the connection between valve 11 and pipe 12, ensuring that the connection between valve 11 and pipe 12 can operate safely and stably in various complex working environments.

[0060] Four arc-shaped rubber blocks 38 form an annular compression at the bottom of the connection between valve 11 and pipe 12, creating a sealing barrier at the bottom of the connection between valve 11 and pipe 12. The arc-shaped rubber blocks 38 fit tightly against the connection between valve 11 and pipe 12, preventing fluid from leaking out of the connection. This significantly improves the sealing performance of the connection between valve 11 and pipe 12 and effectively prevents fluid leakage.

[0061] When the quick-connect component is reset, in the state of disconnecting the connection between valve 11 and pipe 12 as described above, during the operation of the anti-drip component, specifically, the slide plate 32 will drive the toothed plate 33 to continue moving upward. At this time, the upward movement of the toothed plate 33 will no longer mesh with the gear 36, that is, the toothed plate 33 will no longer contact the gear 36. At this time, the upward movement of the toothed plate 33 will not cause the connecting rod 37 to continue rotating towards pipe 12. When the anti-drip component operates to the point where the upper truncated cone 29 moves downward and no longer abuts against the slider 213, the middle tube 24 drives the connecting block 23 to move downward synchronously, that is, the toothed plate 33 moves downward and re-meets the gear 36. As the middle tube 24 continues to move downward, the toothed plate 33 causes the gear 36 to drive the connecting rod 37 to rotate to a horizontal state, that is, the arc-shaped rubber block 38 no longer abuts against pipe 12. At this time, pipe 12 can be removed from inside valve 11.
