Description

Technical Field

[0001] This invention relates to the field of butterfly valve technology, specifically a high-performance dual-channel butterfly valve. Background Technology

[0002] A butterfly valve is a type of valve whose closing element is a disc that rotates around a valve shaft to open and close. Valves can be used to control the flow of various types of fluids, including air, water, steam, various corrosive media, slurry, oil, liquid metals, and radioactive media. In pipelines, they primarily function as shut-off and throttling devices. The butterfly valve's opening and closing element is a disc-shaped plate that rotates around its own axis within the valve body to achieve opening, closing, or regulation. A butterfly valve uses a disc-type opening and closing element that rotates approximately 90 degrees back and forth to open, close, or regulate the flow of the medium. Butterfly valves are not only simple in structure, small in size, lightweight, economical in material consumption, small in installation dimensions, and low in driving torque, but they also simultaneously possess excellent flow regulation capabilities and sealing characteristics, making them one of the fastest-growing valve types in the past decade or so.

[0003] Most butterfly valves currently used on the market are single-channel valves. However, single-channel butterfly valves have limited functions, allowing only the same gas or liquid to enter or exit. They cannot switch between single-channel and dual-channel operation, cannot reverse direction, have relatively simple filtration functions, and cannot perform automatic cleaning. Summary of the Invention

[0004] The purpose of this invention is to provide a high-performance dual-channel butterfly valve to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-performance dual-channel butterfly valve, comprising a flow-dividing assembly, a valve body assembly, and a filter assembly. One end of the valve body assembly is connected to the flow-dividing assembly via a flange. The end of the valve body assembly away from the flow-dividing assembly is fixedly connected to the filter assembly. The valve body assembly includes a valve body and a disc. The disc is fixedly and rotatably connected inside the valve body. The filter assembly includes a filter chamber, a sliding groove, and a rubber frame. One end of the valve body is fixedly connected to the filter chamber. The middle of the filter chamber is provided with a sliding groove. The rubber frame is slidably connected inside the sliding groove. A filter plate is slidably connected inside the rubber frame. One end of the filter plate is fixedly connected to the filter plate. The angle between the reset plate and the filter plate is an acute angle. The end of the rubber frame near the reset plate is provided with a reset groove. A reset spring is fixedly connected inside the reset groove. The reset spring is fixedly connected to the reset plate. A lifting groove is opened inside the sliding groove. A lifting screw is rotatably connected inside the lifting groove. A lifting slider is threadedly connected to the outer side of the lifting screw. The lifting slider is fixedly connected to the rubber frame.

[0006] Preferably, the diversion assembly includes a diversion chamber, a rubber shaft, and a conversion plate. The diversion chamber is connected to the side of the valve body away from the filter chamber via a flange. The rubber shaft is rotatably connected to the side of the diversion chamber away from the valve body. The conversion plate is fixedly connected to the outer side of the rubber shaft. The top and bottom of the conversion plate are slidably connected to the inner wall of the diversion chamber. Two right-angled triangular limiting blocks are symmetrically provided on the inner wall of the diversion chamber. A sealing gasket is provided on the outer side of the limiting blocks.

[0007] Preferably, an adjustment switch is provided at the top of the diversion chamber and the top of the valve body. The adjustment switch includes a worm gear, a worm, and an adjustment box. The worm is rotatably connected inside the adjustment box, and the worm gear is meshed with the outside of the worm. The worm gear is rotatably connected to the adjustment box, and a handwheel is rotatably connected to the outside of the adjustment box. The worm is fixedly connected to the handwheel.

[0008] Preferably, the inner wall of the valve body is provided with a sealing ring, which is slidably connected to the disc.

[0009] Preferably, the center of the disc and the axis of the rubber shaft are both fixedly connected to the corresponding worm gear via a rotating shaft.

[0010] Preferably, a connecting pipe is provided on the side of the filter chamber away from the valve body, and the area of ​​the rubber frame is larger than the cross-sectional area of ​​the rubber frame.

[0011] Preferably, a PLC controller is provided on the outside of the filter chamber, and the micro motor is electrically connected to the PLC controller. Both the PLC controller and the micro motor are connected to a power source via wires.

[0012] Preferably, the end of the flow divider assembly away from the valve body assembly is fixedly connected to two flow divider pipes, and the rubber shaft is located between the two flow divider pipes.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. Driven by a micro motor, when the filter plate on the upper part of the rubber frame extends out of the filter chamber, the filter plate on the lower part of the rubber frame fills the water inlet of the connecting pipe for filtration. When the filter plate extends out of the filter chamber, the reset spring begins to reset without the pressure of the filter chamber. At this time, the reset spring pushes the reset plate to slide inside the reset groove, and the reset plate pushes the filter plate out of the rubber frame, thereby pushing out the impurities collected inside the rubber frame and achieving automatic cleaning.

[0015] 2. When a pipeline needs to be divided into two branches, the rubber shaft is rotated by adjusting the switch, so that the conversion plate is parallel to the diversion pipe. After the water flows through the valve body, it is divided into two branches and diverted through the diversion pipe. When a single diversion pipe needs to be transported, the rubber shaft is rotated by adjusting the switch, and the rubber shaft drives the conversion plate to rotate. The conversion plate and the inner wall of the diversion chamber form a closed right-angled triangular space. At this time, one of the diversion pipes is closed, allowing the single diversion pipe to flow, thereby realizing the reversal. Attached Figure Description

Detailed Implementation

[0025] 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 scope of protection of the present invention.

[0026] Please see Figure 1-8 This invention provides a technical solution: a high-performance dual-channel butterfly valve, comprising a flow-diverting assembly 1, a valve body assembly 2, and a filter assembly 3. One end of the valve body assembly 2 is connected to the flow-diverting assembly 1 via a flange, and the other end of the valve body assembly 2 away from the flow-diverting assembly 1 is fixedly connected to the filter assembly 3. The valve body assembly 2 includes a valve body 5 and a disc 20, with the disc 20 fixedly and rotatably connected inside the valve body 5. The filter assembly 3 includes a filter chamber 6, a sliding groove 7, and a rubber frame 13. One end of the valve body 5 is fixedly connected to the filter chamber 6, and the middle of the filter chamber 6 has a sliding groove 7. The rubber frame 13 is slidably connected inside the sliding groove 7, and a filter plate 14 is slidably connected inside the rubber frame 13. One end of the filter plate 14 is fixedly connected to the filter plate 14. Water flows through the filter plate 14 into the valve body 5. During this period, the filter plate 14 filters the liquid. After filtering for a period of time, the PLC controller 18 controls the micro motor 12 to work, and the micro motor 12 drives the lifting slide plate 14 through the lifting screw 10. When the filter plate 14 on the upper part of the rubber frame 13 extends out of the filter chamber 6, the filter plate 14 on the lower part of the rubber frame 13 fills the water inlet position of the connecting pipe 8 for filtration. When the filter plate 14 extends out of the filter chamber 6, the reset spring 16 begins to reset without the pressure of the filter chamber 6. At this time, the reset spring 16 pushes the reset plate 17 to slide inside the reset groove 15. The reset plate 17 pushes the filter plate 14 out of the rubber frame 13, thereby pushing out the impurities collected inside the rubber frame 13. The angle between the reset plate 17 and the filter plate 14 is an acute angle structure. The end of the rubber frame 13 near the reset plate 17 is provided with a reset groove 15. The reset spring 16 is fixedly connected inside the reset groove 15. The reset spring 16 is fixedly connected to the reset plate 17. The sliding groove 7 is provided with a lifting groove 9. The lifting screw 10 is rotatably connected inside the lifting groove 9. The lifting slider 11 is threadedly connected to the outside of the lifting screw 10. The lifting slider 11 is fixedly connected to the rubber frame 13.

[0027] Furthermore, the diversion assembly 1 includes a diversion chamber 4, a rubber shaft 24, and a conversion plate 29. The diversion chamber 4 is connected to the side of the valve body 5 away from the filter chamber 6 via a flange. The rubber shaft 24 is rotatably connected to the side of the diversion chamber 4 away from the valve body 5. The conversion plate 29 is fixedly connected to the outside of the rubber shaft 24. The top and bottom of the conversion plate 29 are slidably connected to the inner wall of the diversion chamber 4. Two right-angled triangular limiting blocks 27 are symmetrically provided on the inner wall of the diversion chamber 4. A sealing gasket is provided on the outside of the limiting block 27. The sealing performance is enhanced by the cooperation between the sealing gasket 28 and the conversion plate 29.

[0028] Furthermore, both the top of the diversion chamber 4 and the top of the valve body 5 are equipped with adjustment switches 26. The adjustment switch 26 includes a worm gear 22, a worm 23, and an adjustment box 21. The worm 23 is rotatably connected inside the adjustment box 21, and the worm gear 22 is meshed with the outside of the worm 23. The worm gear 22 is rotatably connected to the adjustment box 21, and a handwheel is rotatably connected to the outside of the adjustment box 21. The worm 23 is fixedly connected to the handwheel. The handwheel drives the worm 23 to rotate, the worm 23 drives the worm gear 22, and the worm gear 22 drives the rotating shaft to rotate, thereby realizing the closing and switching of the valve. When the lead angle of the worm 23 is less than the equivalent friction angle between the meshing teeth, the mechanism has self-locking properties and can achieve reverse self-locking.

[0029] Furthermore, the inner wall of the valve body 5 is provided with a sealing ring 19, which is slidably connected to the disc 20 to facilitate maintaining the valve's sealing performance.

[0030] Furthermore, the center of the disc plate 20 and the axis of the rubber shaft 24 are both fixedly connected to the corresponding worm gear 22 via a rotating shaft. The rubber shaft 24 is rotated by the adjusting switch 26, so that the conversion plate 29 is parallel to the diversion pipe 25. At this time, the water flow is divided into two branches after passing through the valve body 5 and then diverted through the diversion pipe 25. When it is necessary to transport water through a single diversion pipe 25, the rubber shaft 24 is rotated by the adjusting switch 26, and the rubber shaft 24 drives the conversion plate 29 to rotate. The conversion plate 29 and the inner wall of the diversion cavity 4 form a closed right-angled triangular space, which closes one of the diversion pipes 25, allowing the single diversion pipe 25 to flow.

[0031] Furthermore, a connecting pipe 8 is provided on the side of the filter chamber 6 away from the valve body 5, and the area of ​​the rubber frame 13 is larger than the cross-sectional area of ​​the rubber frame 13, which facilitates the filtration of the passing water flow and prevents it from leaking.

[0032] Furthermore, a PLC controller 18 is provided on the outside of the filter chamber 6, and the micro motor 12 is electrically connected to the PLC controller 18. Both the PLC controller 18 and the micro motor 12 are connected to the power supply through wires, which facilitates automatic cleaning of the filtered waste.

[0033] Furthermore, the end of the diversion assembly 1 away from the valve body assembly 2 is fixedly connected to two diversion pipes 25. The rubber shaft 24 is located between the two diversion pipes 25. The rubber shaft 24 drives the conversion plate 29 to rotate. The conversion plate 29 and the inner wall of the diversion cavity 4 form a closed right-angled triangular space. At this time, one of the diversion pipes 25 is closed, allowing the flow of a single diversion pipe 25, thereby realizing the reversal.

[0034] Specifically, when using this invention, the connecting pipe 8 is connected to the water inlet interface, and water flows into the filter chamber 6 through the connecting pipe 8. The water then flows into the valve body 5 through the filter plate 14. During this period, the filter plate 14 filters the liquid. After filtering for a period of time, the PLC controller 18 controls the micro motor 12 to work. The micro motor 12 drives the lifting slider 11 to rise and fall through the lifting screw 10. When the filter plate 14 on the upper part of the rubber frame 13 extends out of the filter chamber 6, the filter plate 14 on the lower part of the rubber frame 13 fills the water inlet position of the connecting pipe 8 for filtration. When the filter plate 14 extends out of the filter chamber 6, the reset spring 16 begins to reset without the pressure of the filter chamber 6. At this time, the reset spring 16 pushes the reset plate 17 to slide inside the reset groove 15. The reset plate 17 pushes the filter plate 14 out of the rubber frame 13, thereby pushing out the impurities collected inside the rubber frame 13. Then, the micro motor 16 pushes the filter plate 14 out of the rubber frame 13. When the motor 12 reverses, the rubber frame 13 moves downward, thereby moving the upper filter plate 14 to its original position. Under the same principle, the filter plate 14 at the lower part of the rubber frame 13 pushes out impurities. The filtered liquid enters the valve body 5. The regulating switch 26 drives the disc 20 to rotate inside the valve body 5, thereby adjusting the flow rate. When it is necessary to split a pipeline into two branches, the regulating switch 26 drives the rubber shaft 24 to rotate, making the conversion plate 29 parallel to the diversion pipe 25. At this time, the water flow is split into two branches after passing through the valve body 5 and then diverted through the diversion pipe 25. When it is necessary to transport a single diversion pipe 25, the regulating switch 26 drives the rubber shaft 24 to rotate, and the rubber shaft 24 drives the conversion plate 29 to rotate. The conversion plate 29 and the inner wall of the diversion chamber 4 form a closed right-angled triangular space. At this time, one of the diversion pipes 25 is closed, allowing the single diversion pipe 25 to flow, thereby achieving reversal.
