Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of valves, and particularly relates to a high-pressure-resistant eccentric butterfly valve with adjustability. BACKGROUND

[0002] A butterfly valve, simply referred to as a butterfly valve, is a valve in which a disc-shaped closure element rotates about its own axis to achieve opening and closing. The butterfly valve is mainly used for cutting and throttling in a pipeline. The opening and closing element of the butterfly valve is a disc-shaped butterfly plate which rotates in the valve body about its own axis to achieve the purpose of opening, closing or adjusting. The butterfly valve is usually less than 90 degrees from full opening to full closing. The butterfly valve and the butterfly rod itself have no self-locking capability. In order to position the butterfly plate, a worm gear reducer is installed on the valve rod. The worm gear reducer not only enables the butterfly plate to have self-locking capability and stop at any position, but also improves the operation performance of the valve.

[0003] When the existing butterfly valve controls the flow of water, the butterfly plate first blocks the water flow for a long time. The water flow blocked for a long time accumulates a large water pressure. When the butterfly plate is rotated, the excessive water flow may cause unstable rotation of the butterfly plate, thereby causing the control system to be unable to smoothly adjust the valve.

[0036] The present application is characterized in that the cooperation of the butterfly valve mechanism, the moving mechanism and the unfolding mechanism is set, the electric motor is started, the electric motor makes the butterfly plate rotate, the butterfly plate gradually does not seal the base during the rotation process, and the water flow can move, the rotation amplitude of the butterfly plate can control the water flow, when the butterfly plate and the base are completely attached, the water flow can be prevented, when the butterfly plate rotates, the deflection angle of the butterfly plate indirectly makes the rotating special-shaped block move, because the rotating special-shaped block gradually moves away from the fixed shell, and the rotating ring rotates on the side wall of the fixed shell, so the rotating bent plate rotates around the rotating special-shaped block, the rotating bent plate indirectly drives the square fan plate to rotate, the square fan plate can contact the water flow surface, and the water flow is hindered, the flow rate of the water flow is reduced, the pressure of the fluid is reduced, the pressure is prevented from being too high, the water flow causes too large impact force on the butterfly plate, the rotation stability of the butterfly plate is affected, the precision control of the butterfly plate on the flow is improved, and the sliding rod continues to drive the fan blade assembly to move forward, so that the square fan plate can push the water flow in the opposite direction, and the flow rate of the water flow is further reduced.

[0037] This invention, through the coordinated arrangement of a butterfly valve mechanism, a moving mechanism, an unfolding mechanism, and an auxiliary mechanism, allows the square fan plate to rotate slightly around the fixed shell. The rotating irregular block indirectly drives the connecting rod to slide along the inner wall of the arc-shaped hole. As the connecting rod slides, it contacts the side wall of the arc-shaped frame, causing the arc-shaped frame to move the sliding plate. When two adjacent sliding plates contact each other, the resulting reaction force causes a slight wobbling of the connecting rod. This, in turn, causes the square fan plate to vibrate slightly, dislodging small particles of impurities from the conical hole within the square fan plate. These impurities are no longer carried along by the water flow but instead re-flow with the water, reducing the impact force of the flow and improving the protection of the butterfly plate. When two sliding plates contact each other, the arc-shaped spring is excessively compressed. The elastic deformation of the arc-shaped spring causes the two sliding plates to move away from each other, resulting in the arc-shaped frame exerting reverse pressure on the connecting rod, indirectly causing the square fan plate to rotate in the opposite direction, thus improving the agitation effect of the square fan plate on the water flow.

[0050] Moving mechanism 2, located inside butterfly valve mechanism 1, is used to seal butterfly valve mechanism 1;

[0051] Deployment mechanism 3, installed outside the moving mechanism 2, is used to obstruct the flow of water; and

[0052] Auxiliary mechanism 4 is installed outside the deployment mechanism 3 and is used to clean the moving mechanism 2 through the operation of the deployment mechanism 3;

[0054] The above solution involves the unfolding mechanism making contact with the surface through which the water flows, thus obstructing the flow and reducing its velocity. This reduces fluid pressure, preventing excessive pressure and potential impact from the water flow on the butterfly valve mechanism, which could affect its rotational stability. This also improves the butterfly valve mechanism's precise flow control.

[0064] The sealing member is arranged to seal the power member.

[0065] The unfolding mechanism 3 comprises;

[0066] a fan blade assembly 31, which is rotatably arranged with the moving member;

[0067] a rotating assembly 32, which is rotatably connected to the outside of the fan blade assembly 31 and is used to hinder the flow of water;

[0068] The fan blade assembly 31 comprises a rotating special-shaped block 311 rotatably connected to the outer wall of the end of the sliding rod 23 away from the fixed plate 24, the outer wall of the rotating special-shaped block 311 is rotatably connected with three rotating bent plates 312 respectively, the side wall of one end of the rotating bent plate 312 is fixedly connected with a circular rod 314, the outer wall of the circular rod 314 is fixedly connected with a square fan plate 315, and a plurality of conical holes 316 are formed in one side of the outer wall of the square fan plate 315;

[0069] The rotating assembly 32 is arranged to hinder the flow of water.

[0070] By adopting the above solution, the conical hole 316 can be set so that when the water flows into contact with the square fan plate 315, it enters the interior of the conical hole 316, thereby dividing the water flow and reducing the impact force of the water flow.

[0071] Auxiliary mechanism 4 includes;

[0072] A cleaning component, which is fixedly installed with the fan blade assembly 31, is used to clean the seals;

[0073] The auxiliary component is slidably disposed inside the moving component;

[0074] The cleaning component includes three connecting plates 41 fixedly connected to one side of the outer wall of the rotating irregular block 311. A connecting rod 42 is fixedly connected to the side of the connecting plate 41 away from the rotating irregular block 311. A bent plate 43 is fixedly connected to the end of the connecting rod 42 away from the connecting plate 41. A flexible rack 44 is fixedly connected to one side of the bent plate 43.

[0075] The cleaning component is designed to clean the seal.

[0076] The outer frame includes a lower connecting seat 17 connected to the bottom of the base 11. The inner wall of the lower connecting seat 17 is rotatably connected to a lower rotating shaft 16. The top outer wall of the lower rotating shaft 16 is fixedly connected to the inner wall of the butterfly plate 15. Two round tubes 18 are connected to both sides of the base 11.

[0077] The sealing element includes a fixing plate 24 fixedly connected to one end of the sliding rod 23. A titanium alloy spring 27 is fixedly connected to the side of the fixing plate 24 near the sliding rod 23.

A sealing plate 26 is fixedly connected to the end of the crossbar 25 away from the fixing plate 24. The sealing plate 26 is provided to seal the contact area between the butterfly plate 15 and the base 11. The outer wall of the sealing plate 26 is slidably connected to the inner wall of the base 11.

[0078] The above solution is adopted: by setting the flexible rack 44, when the connecting rod 42 rotates, the connecting rod 42 drives the bending plate 43 to rotate, and the bending plate 43 drives the flexible rack 44 to rotate, which can scrape the outer wall of the titanium alloy spring 27, prevent small particles of impurities from getting stuck inside the titanium alloy spring 27, and improve the working stability of the titanium alloy spring 27.

[0079] The rotating assembly 32 includes a telescopic rotating rod 322 rotatably connected to one side of the inner wall of the rotating bending plate 312, and a rotating ring 323 is rotatably connected to one end of the telescopic rotating rod 322 away from the rotating bending plate 312.

[0080] A rotating ring 323 is provided. The outer wall of the rotating ring 323 away from the telescopic rotating rod 322 is rotatably connected to the outer wall of the fixed shell 22. The fixed shell 22 has three arc-shaped holes 324 on the outer wall near the rotating ring 323. One end of the connecting rod 42 is slidably connected to the inner wall of the arc-shaped hole 324.

[0081] The auxiliary components include an arc-shaped rod 45 that penetrates and is slidably connected to the inner cavity of the fixed shell 22. There are six arc-shaped rods 45. The outer wall of one end of the arc-shaped rod 45 is slidably connected to the inner wall of the arc-shaped hole 324. A sliding plate 46 is fixedly connected to one end of the arc-shaped rod 45. The outer wall of the sliding plate 46 is slidably connected to the inner cavity of the fixed shell 22. An arc-shaped spring 47 is fixedly connected between two adjacent sliding plates 46.

[0082] The above scheme is adopted: when the two sliding plates 46 come into contact, the arc spring 47 is over-compressed. The elastic deformation of the arc spring 47 causes the two sliding plates 46 to move away from each other, thereby causing the arc rod frame 45 to press the connecting rod 42 in the opposite direction, indirectly causing the square fan plate 315 to rotate in the opposite direction, thus improving the stirring effect of the square fan plate 315 on the water flow.

[0083] Working principle and usage process of this invention:

[0084] When the electric motor 14 is activated, it drives the upper rotating shaft 13 to rotate, which in turn drives the butterfly plate 15 to rotate. As the butterfly plate 15 rotates, it gradually stops sealing the base 11, allowing water to flow freely. The water flow rate can be controlled by the rotation amplitude of the butterfly plate 15. When the butterfly plate 15 is completely in contact with the base 11, water flow is stopped. When the butterfly plate 15 rotates, the deflection angle it generates causes the fixed plate 24 to drive the sliding rod 23 to slide laterally along the inner wall of the fixed shell 22. The sliding rod 23 gradually moves away from the upper rotating shaft 13, causing the rotating irregular block 311 to move. Because the rotating irregular block 311 gradually moves away from the fixed shell 22, and the rotating ring 323 rotates on the side wall of the fixed shell 22, the rotating ring 323 drives the telescopic rotating rod. 322 and the rotating curved plate 312 rotate around the rotating irregular block 311 as the axis. The rotating curved plate 312 drives the round rod 314 to rotate, and the round rod 314 drives the square fan plate 315 to rotate, also rotating around the rotating irregular block 311 as the axis. At this time, the square fan plate 315 will gradually expand its contact surface with water during rotation, so that the square fan plate 315 can contact the surface where the water flows, obstructing the water flow and reducing the water flow velocity. This also reduces the fluid pressure from the side, preventing the water flow from having too high a pressure and causing too much impact force on the butterfly plate 15, which would affect the rotational stability of the butterfly plate 15. This also improves the precise control of the flow rate by the butterfly plate 15. In addition, the sliding rod 23 continues to drive the fan blade assembly 31 to move forward, which enables the square fan plate 315 to push the water flow in the opposite direction, further reducing the water flow velocity.

[0085] As the square fan plate 315 gradually rotates and comes into contact with the water flow surface, the tapered design of the conical hole 316, with a larger opening on the side facing the water flow and a smaller opening on the opposite side, allows the larger opening of the conical hole 316 to collect small particles of impurities adhering to the water flow. This reduces the risk of collision and scratches to the butterfly plate 15 when impurities and water flow together, thus improving the protection of the butterfly plate 15. Furthermore, the square fan plate 315's identical shape to the fan allows for... When the water flows, the square fan plate 315 rotates slightly. The square fan plate 315 drives the rotating irregular block 311 to rotate around the sliding rod 23 as the axis. Since the rotating ring 323 rotates at the side wall of the fixed shell 22, the square fan plate 315 can drive the rotating ring 323 in the rotating assembly 32 to rotate around the side wall of the fixed shell 22. During the rotation of the square fan plate 315, the flow direction of the water can be slightly disturbed, the fluid pressure can be reduced from the side, and the operational stability of the butterfly plate 15 can be improved.

[0086] When the rotating ring 323 rotates slightly around the fixed shell 22, it causes the rotating irregular block 311 in the fan blade assembly 31 to drive the connecting plate 41 to rotate. The connecting plate 41 then drives the connecting rod 42 to rotate. The connecting rod 42 slides on the inner wall of the arc-shaped hole 324. When the connecting rod 42 slides, it will contact the side wall of the arc-shaped frame 45, causing the arc-shaped frame 45 to drive the sliding plate 46 to move. When two adjacent sliding plates 46 come into contact, the resulting reaction force can cause the connecting rod 42 to shake slightly. The connecting rod 42 indirectly causes the square fan plate 315 to vibrate slightly, causing small particles of impurities inside the conical hole 316 in the square fan plate 315 to fall off. At this time, the small particles of impurities are no longer carried along with the water flow, but flow with the water again, reducing the flow impact of the small particles and improving the protection effect of the butterfly plate 15.
