Description

Technical Field

[0001] This invention relates to the field of butterfly valve processing technology, specifically to a valve plate sealing installation mechanism for a butterfly valve. Background Technology

[0002] A butterfly valve, also known as a flap valve, is a simple regulating valve that can be used for on / off control of low-pressure pipeline media. A butterfly valve is a type of valve in which the closing element (valve disc or butterfly plate) is a disc that rotates around the valve shaft to achieve opening and closing.

[0003] In the existing technology, there is a tightly fitted sealing gasket around the butterfly valve. Since the butterfly plate and shaft of some butterfly valves are integrally formed, when assembling the sealing gasket, one end of the sealing gasket needs to be put on first, and then the other end of the sealing gasket needs to be put on. The sealing gasket needs to be stretched repeatedly. Manual operation of pulling is not accurate, requires repeated adjustment, and is inefficient. Summary of the Invention

[0063] The working principle and beneficial effects of this invention are as follows:

[0064] In this invention, when using the valve plate sealing installation mechanism of the butterfly valve, the sealing gasket to be installed is first clamped by the first electric clamp.

Then, by adjusting the rotation and lifting position of the first electric clamp, the sealing gasket is placed on the mounting table. At this time, the hole on the sealing gasket is aligned with the cylindrical hole on the mounting table. Then, the two telescopic clamps extend upward to clamp the bottom of the sealing gasket, achieving initial positioning. Then, by controlling the lifting of the second lifting drive, the second electric clamp clamps one end of the butterfly plate shaft and places it in the position of the sealing gasket. At the same time, the first lifting drive rises, causing the first electric clamp to move upward to clamp the upper part of the sealing gasket. Then, the first electric clamp is controlled to start flipping, thereby twisting the upper part of the sealing gasket to one side. Since the lower part of the sealing gasket is clamped by the telescopic clamp, the lower part of the sealing gasket does not move, achieving the effect of the upper part of the sealing gasket being tilted, so that the lower part of its inner ring surface is exposed. Then, the second electric clamp directly places the other shaft at the bottom of the butterfly plate into the hole of the sealing gasket, and through the descent of the third lifting drive, it drives it to be inserted into the cylindrical hole on the mounting platform, realizing the initial automatic installation of the sealing gasket. Then, the first electric clamp is controlled to release the sealing gasket, and the sealing gasket can be completely fitted onto the outer ring surface of the butterfly plate through the auxiliary installation mechanism, realizing the automatic installation of the sealing gasket and butterfly plate of the butterfly valve, improving the installation efficiency.

[0083] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0084] like Figures 1 to 16 As shown, this embodiment proposes a valve plate sealing mounting mechanism for a butterfly valve, including a base plate 1 and a mounting platform 18, wherein the mounting platform 18 is mounted on the base plate 1.

[0085] It also includes,

[0086] A sealing ring clamping mechanism is mounted on the machine base plate 1.

[0087] A butterfly valve placement mechanism is installed on the base plate 1. An arc-shaped placement groove is provided on the mounting platform 18 for placing the butterfly valve sealing gasket. A cylindrical hole is located at the center of the arc-shaped placement groove on the mounting platform 18. Two telescopic clamps 19 are provided on both sides of the cylindrical hole on the mounting platform 18.

[0088] An auxiliary installation mechanism is provided to assist in the installation of the sealing gasket onto the outer ring surface of the butterfly plate.

[0089] The sealing ring clamping mechanism includes,

[0090] The first electric slide rail 2 is mounted on the machine base plate 1.

[0091] The first electric slide block 3 is slidably mounted on the first electric slide rail 2.

[0092] The first lifting drive component 4 is mounted on the first electric slide block 3.

[0093] Connecting seat 5, which is mounted on the lifting end of the first lifting drive component 4 via an electric rotating shaft seat.

[0094] The first electric clamp 6 is horizontal and is mounted on the connecting seat 5 via an electric rotating shaft seat.

[0095] The butterfly plate placement mechanism includes,

[0096] The second lifting drive component 7 is mounted on the machine base plate 1.

[0097] The first mounting plate 8 is mounted on the lifting end of the second lifting drive component 7 via an electric rotating shaft seat.

[0098] The third lifting drive component 9 is mounted on the first mounting plate 8.

[0099] The second electric clamp 16 is installed on the lifting end of the third lifting drive 9.

[0100] In this embodiment, when using the valve plate sealing installation mechanism of the butterfly valve, the sealing gasket to be installed is first clamped by the first electric clamp 6. The first electric clamp 6 moves horizontally via the first electric slide block 3 on the first electric slide rail 2. Then, by adjusting the rotation and lifting position of the first electric clamp 6, the sealing gasket is placed on the mounting platform 18. At this time, the hole on the sealing gasket is aligned with the cylindrical hole on the mounting platform 18. Then, the two telescopic clamps 19 extend upward to clamp the bottom of the sealing gasket, achieving initial positioning. Then, by controlling the lifting of the second lifting drive 7, the second electric clamp 16 is driven to clamp the shaft at one end of the butterfly plate and place it in the position of the sealing gasket. At the same time, the first lifting drive 4 rises, driving the first electric clamp 6 to move upward to place the sealing gasket... The upper part is clamped, and then the first electric clamp 6 is controlled to start flipping, thereby twisting the upper part of the sealing gasket to one side. Since the lower part of the sealing gasket is clamped by the telescopic clamp 19, the lower part of the sealing gasket does not move, achieving the effect of the upper part of the sealing gasket being tilted, so that the lower part of its inner ring surface is exposed. Then the second electric clamp 16 directly places the other shaft at the bottom of the butterfly plate into the hole of the sealing gasket, and through the descent of the third lifting drive 9, it drives it to be inserted into the cylindrical hole on the mounting platform 18, realizing the initial automatic installation of the sealing gasket. Then the first electric clamp 6 is controlled to release the sealing gasket, and the sealing gasket can be completely fitted onto the outer ring surface of the butterfly plate through the auxiliary installation mechanism, realizing the automatic installation of the sealing gasket and butterfly plate of the butterfly valve, improving the installation efficiency.

[0101] The butterfly plate placement mechanism also includes,

[0102] The downward pressure column 10 is installed at the lifting end of the third lifting drive component 9.

[0103] Mounting cylinder 11, which is slidably connected to the outer wall of the pressing column 10.

[0104] Two first elastic telescopic rods 12 are provided, and the two first elastic telescopic rods 12 are located inside the mounting cylinder 11. The first end of the first elastic telescopic rod 12 is connected to the bottom surface of the lower pressure column 10, and the second end of the first elastic telescopic rod 12 is connected to the inner bottom surface of the mounting cylinder 11.

[0105] Ball-head pressure rod 13, which is fixed to the bottom of the lower pressure column 10.

[0106] A rotating rod 14 is rotatably mounted on the mounting cylinder 11 via a torsion spring pivot seat 17. The second electric clamp 16 is fixedly connected to the bottom of the rotating rod 14.

[0107] The rotating control column 15 is a quarter-cylinder, and its top surface is a spiral inclined surface along the circumferential direction. The rotating control column 15 is fixed to the rotating rod 14 and is located below the ball-head pressure rod 13.

[0108] In this embodiment, after the other shaft at the bottom of the butterfly plate is placed directly into the hole of the sealing gasket and inserted into the cylindrical hole on the mounting platform 18, the shaft at the bottom of the butterfly plate has already contacted the bottom of the cylindrical hole. A bearing plate is provided at the bottom of the cylindrical hole, and the shaft at the bottom of the butterfly plate will abut against the bearing plate. Then, the second lifting drive 7, in conjunction with the third lifting drive 9, continues to descend, that is, it drives the second electric clamp 16 to continue to move downward. As it continues to descend, the mounting cylinder 11 remains stationary. Then, the third lifting drive 9 drives the lower pressure column 10 to move downward within the mounting cylinder 11, causing the first elastic telescopic rod 12 to begin to compress, and simultaneously driving the ball head pressure rod 13 to move downward. The ball head part of the ball head pressure rod 13 will move downward to abut against the bearing plate. The upper surface of the rotary control column 15 is held, and the column gradually slides along the inclined surface of the upper surface of the rotary control column 15. Under the pressure of the ball head pressure rod 13, the rotary control column 15 slowly rotates, which in turn drives the rotating rod 14 to rotate. Then the rotating rod 14 rotates, which in turn drives the second electric clamp 16 to rotate. The second electric clamp 16 then drives the butterfly plate it holds to rotate until the rotary control column 15 finishes rotating. The angle of the rotary control column 15 is ninety degrees. That is, after the rotation is completed, the butterfly plate is perpendicular to the plane where the sealing gasket is located. Then the second electric clamp 16 releases the shaft at the upper part of the butterfly plate and moves upward. At this time, the butterfly plate is perpendicular to the sealing gasket, which makes it easy for the upper side of the sealing gasket to be fitted onto the upper side of the butterfly plate. Then the auxiliary installation mechanism fits the sealing gasket onto the butterfly plate.

[0109] The auxiliary installation mechanism includes a convergence mechanism and a pressing mechanism, wherein the convergence mechanism includes,

[0110] A translation component, which is mounted on the base plate 1.

[0111] Platform 22, which is mounted on the moving end of the translation component.

[0123] An isosceles inclined frame 32 is fixed to the platform 22 by support rods on both sides. The outer surfaces of the two converging rods 31, away from the mounting platform 18, slide in contact with the lower surfaces of the two inclined rods of the isosceles inclined frame 32.

[0124] The fourth elastic telescopic rod 45, two of which are provided, are installed on the top of the two sliding frames 29 in opposite directions.

[0125] There are two sliding frames 46, which are respectively installed on the telescopic ends of the two fourth elastic telescopic rods 45. Each sliding frame 46 is connected to the two sliding seats 30 on the same side.

[0126] The auxiliary installation mechanism further includes an upward-lifting component, which includes,

[0127] The second connecting frame 33 is mounted on the lifting plate 25.

[0128] The fourth mounting plate 34 is fixedly connected to the bottom of the second connecting frame 33.

[0129] Two telescopic drive components 35 are provided and are mounted on the fourth mounting plate 34.

[0130] The fifth mounting plate 36 is mounted on the telescopic ends of the two telescopic drive members 35.

[0131] There are two upward-mounting rods 37, which are installed in parallel on the fifth mounting plate 36, with a gap between them.

[0132] The auxiliary installation mechanism further includes a pressing component, which includes,

[0133] A downward pressure control assembly is mounted on the second connecting frame 33 and the isosceles inclined frame 32.

[0134] There are two pressure rods 44, which are mounted on the pressure control assembly.

[0135] The pressure control component includes,

[0136] Two sliding frames 38 are provided, each fixed to the isosceles inclined frame 32 by a bracket. The two sliding frames 38 are symmetrically arranged. Each sliding frame 38 is quadrilateral, with one right angle, an acute angle opposite to the right angle, and the other two obtuse angles. The right angle of the sliding frame 38 is located on the lower part of the side closer to the mounting platform 18.

[0137] Two third elastic telescopic rods 39 are provided, and the two third elastic telescopic rods 39 are installed on the second connecting frame 33.

[0138] A sixth mounting plate 40 is mounted on the telescopic ends of the two third elastic telescopic rods 39, and the two downward pressing rods 44 are fixedly connected to the sixth mounting plate 40.

[0139] Two limiting frames 41 are provided and symmetrically installed on the second connecting frame 33.

[0140] Two limiting seats 42 are provided, each of which is slidably disposed within a limiting frame 41. The sixth mounting plate 40 is fixedly connected between the two limiting seats 42.

[0141] There are two sliding columns 43, which are slidably disposed in the two sliding frames 38 respectively, and the two limiting seats 42 are fixedly connected to the two sliding columns 43 respectively.

[0142] The translation component includes a second electric slide rail 20 and a second electric slide block 21. There are two second electric slide rails 20, which are mounted on the machine base plate 1. Each second electric slide rail 20 has a second electric slide block 21 slidably mounted on it. The platform 22 is mounted on top of the two second electric slide blocks 21.

[0143] In this embodiment, after the butterfly plate rotates to be perpendicular to the surface of the sealing gasket, the second electric clamp 16 releases its grip, and the butterfly plate is vertically inserted into the cylindrical hole of the mounting platform 18. Then, the first electric clamp 6 also releases its grip on the sealing gasket. At this time, the sealing gasket rests against one side of the butterfly plate. Then, the second electric slide block 21 is controlled to move on the second electric slide rail 20 towards the mounting platform 18, thereby driving the two converging rods 31 to move to both sides of the sealing gasket. The telescopic drive component 35 is also controlled to extend, and the telescopic drive component 35 drives the fifth mounting plate 36 and the upper lifting rod. 37 moves towards the sealing gasket, causing the two upward-pointing rods 37 to insert into the top position of the inner ring of the sealing gasket. The upper shaft hole of the sealing gasket is located between the two upward-pointing rods 37. Then, the fourth lifting drive 24 begins to rise, causing the fourth lifting drive 24 to drive the lifting plate 25 to move upward, which in turn drives the first connecting frame 26 and the second elastic telescopic rod 27 to move upward. Then, the second elastic telescopic rod 27 drives the third mounting plate 28 to move upward, and the third mounting plate 28 drives the two sliding frames 29 to move upward. The sliding frames 29 are connected by sliding seats 3. The 0-axis causes the two converging rods 31 to move upwards. The two converging rods 31 gradually slide upwards along the lower surface of the isosceles inclined frame 32. As the inclined surface gradually moves towards the center, the two converging rods 31 gradually approach each other, thus squeezing the sealing gasket from both sides towards the center and gradually flattening it. That is, the converging rods 31 slide in the sliding frame 29 through the sliding seat 30, and compress the two fourth elastic telescopic rods 45 through the sliding frame 46. At the same time, the two upward lifting rods 37 also lift the inner top of the sealing gasket upwards. The two converging rods 31 move to the lower surface of the isosceles inclined frame 32. The top is raised, and then the movement stops. At this time, the fourth lifting drive 24 continues to rise, that is, the second elastic telescopic rod 27 begins to stretch, keeping the gathering rod 31 in a clamped state and not moving. That is, the lifting rod 37 continues to move upward until the upper part of the sealing gasket is lifted to the highest point. At this time, the lower surface of the top of the sealing gasket is flush with the top of the upper shaft of the butterfly plate. Then the telescopic drive 35 extends further, driving the fifth mounting plate 36 to move, moving the top of the sealing ring towards the upper shaft of the butterfly plate until the shaft hole at the top of the sealing ring is aligned with the upper shaft of the butterfly plate.

[0144] During the upward movement of the lifting rod 37, the lifting plate 25 also drives the second connecting frame 33 to move upward, causing the second connecting frame 33 to drive the third elastic telescopic rod 39, the sixth mounting plate 40, the limiting frame 41, the limiting seat 42, the sliding column 43, and the pressing rod 44 to move upward synchronously. The sliding column 43 will first move upward gradually along the inclined side of the sliding frame 38 away from the mounting platform 18. During the upward sliding process, it drives the limiting seat 42, the sixth mounting plate 40, and the pressing rod 44 to move synchronously. At the same time, during the upward sliding process, the third elastic telescopic rod 39 is in the extended state at the bottom, and then moves upward from the lowest position. The bottom extends to its initial state, then retracts to its top. Simultaneously, the fifth mounting plate 36 moves, bringing the apex of the sealing ring closer to the upper shaft of the butterfly plate until the upper shaft hole of the sealing ring aligns with the upper shaft of the butterfly plate. Then, the fourth lifting drive 24 retracts, and the lifting rod 37 begins to move slowly downwards. At the same time, the top of the sealing gasket begins to retract downwards, causing the shaft hole of the sealing gasket to fit onto the upper shaft of the butterfly plate. Then, the telescopic drive 35 retracts, and the lifting rod 37 is pulled out from the inside of the sealing gasket. Simultaneously, the third elastic telescopic rod 39 is in a retracted position. In the retracted state, when descending, the sliding column 43 begins to slide down along the inclined side of the top of the sliding frame 38, thus driving the pressing rod 44 to move closer to the sealing gasket until the pressing rod 44 moves above the sealing gasket. At this time, the third elastic telescopic rod 39 is in the extended state. Then, the sliding column 43 moves to the vertical right-angle side of the sliding frame 38 and begins to slide down along the vertical track. That is, after the pressing rod 44 moves to the upper side of the sealing gasket, it begins to slide down. In other words, the two pressing rods 44 will press down on the top of the sealing gasket from both sides of the shaft, so that the sealing gasket can be compressed and fit against the inner butterfly plate. Until the pressing rod 44 is fully depressed, the sliding column 43 moves to the bottom of the vertical right-angle side of the sliding frame 38. Since the third elastic telescopic rod 39 is in an extended state, it will begin to retract, causing the sixth mounting plate 40 to move. The sixth mounting plate 40 causes the limiting seat 42 to move away from the mounting platform 18 in the limiting frame 41, which in turn causes the sliding column 43 and the pressing rod 44 to move synchronously. That is, the pressing rod 44 will leave the top of the sealing ring and return to the initial state. The gathering rod 31, the fifth mounting plate 36 and the pressing rod 44 are all reset, completing the assembly of the butterfly valve's sealing gasket and butterfly plate.

[0145] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
