The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0025] The following describes an embodiment of the utility model based on its overall structure.

[0026] A butterfly valve that is easy to disassemble and assemble, such as Figure 1 - Figure 7 As shown, it includes a valve body 100, a mounting seat 110 is fixedly installed on the outer surface of the lower end of the valve body 100, a base 120 is installed on the right side of the mounting seat 110, a shock absorbing component 300 is arranged inside the base 120, a connecting pipe 130 is fixedly installed on one end of the valve body 100, a disassembly assembly 200 is installed on the outer surface of the right side of the connecting pipe 130, and the connecting pipe 130 is connected to the pipe body 140 through the disassembly assembly 200;

[0027] The disassembly assembly 200 includes a moving ring 210 sleeved on the outer wall of the connecting pipe 130, and the moving ring 210 and the connecting pipe 130 are threadedly connected. A fixing rod 230 is fixed to the right outer wall of the moving ring 210. A through ring 220 is sleeved on the side of the connecting pipe 130 away from the valve body 100, and one end of the fixing rod 230 extends through the through ring 220. A second fixing ring 2980 is sleeved and fixed on the outer wall of one end of the pipe body 140. The inner part of the second fixing ring 2980 A limiting groove 260 is provided, and a first spring 250 is fixedly installed on the inner wall of the limiting groove 260. An inclined block 240 is fixedly installed on one end of the first spring 250 away from the inner wall of the limiting groove 260, and the upper end of the inclined block 240 is fixedly connected to the first spring 250. The outer wall of the second fixed ring 2980 is sleeved with a mounting ring 280, and a rotating ring 290 is sleeved on one side of the tube body 140 close to the mounting ring 280, and the rotating ring 290 is rotatably connected to the tube body 140, and the rotating ring 290 is away from the tube body 140. An extension ring 2910 is fixedly installed at one end of the mounting ring 280, a torsion spring 2930 is sleeved on the outer surface of the lower end of the extension ring 2910, and the outer surface of the torsion spring 2930 is rotatably connected to the first fixing ring 2920, a fixed pulley is fixed in the mounting ring 280 through a rotating shaft, and a connecting rope 270 is attached to the outer surface of the fixed pulley, one end of the connecting rope 270 extends to the inside of the second fixing ring 2980 and is fixedly connected to the inclined block 240, and the other end of the connecting rope 270 extends to be fixed to the rotating shaft. An outer wall of the moving ring 290 and one side of the connecting tube 130 are provided with a mounting hole 2940, a second spring 2950 is fixedly installed in the mounting hole 2940, an alignment block 2960 is fixedly installed on the side of the second spring 2950 away from the mounting hole 2940, an alignment plate 2970 is fixedly installed on one side of the tube body 140, and the alignment plate 2970 corresponds to the size of the mounting hole 2940, the number of the fixing rods 230 is eight groups, and the shape of the fixing rods 230 is hook-shaped.

[0028] When the valve body 100 needs to be docked with the tube body 140, the alignment plate 2970 of the tube body 140 is aligned with the mounting hole 2940 until the alignment plate 2970 completely enters the mounting hole 2940, and the movable ring 210 is rotated to move to the right, and then the movable ring 210 drives the fixing rod 230 to penetrate the interior of the penetrating ring 220 and enter the interior of the second fixing ring 2980. When entering the interior of the second fixing ring 2980, the inclined surface of the fixing rod 230 squeezes the inclined surface of the inclined block 240, driving the inclined block 240 to squeeze the first spring 250, and making the inclined block 240 move toward the interior of the limiting groove 260, until the fixing rod 230 completes entry, and the first spring 250 restores its elastic deformation to drive the inclined block 240 to get stuck in the fixing groove 260. The back side of the hook head of the rod 230 is rotated to complete the installation. When disassembly is required, the rotating ring 290 is rotated, and then the rotating ring 290 drives the connecting rope 270. Since the installation ring 280 has a fixed pulley inside, it has a guiding effect on the connecting rope 270 to reduce friction. When the rotating ring 290 rotates, it will drive the connecting rope 270, and then the connecting rope 270 drives the inclined block 240 to move toward the inside of the limiting groove 260, thereby releasing the fixation of the fixed rod 230. When the rotating ring 290 is rotated, the rotating ring 290 simultaneously drives the extension ring 2910 to rotate inside the first fixed ring 2920 and drives the torsion spring 2930 to rotate, and the torsion spring 2930 achieves the function of automatic reset, thereby completing the disassembly. The operation is simple and the disassembly and assembly efficiency is improved.

[0029] Please refer to Figure 6 - Figure 7 The shock absorbing assembly 300 includes a compression plate 310 that slides inside the base 120, and the compression plate 310 is fixedly connected to the mounting seat 110. Telescopic columns 330 are fixedly installed on the lower surfaces of both ends of the compression plate 310. A fixing groove 350 is opened at the bottom end of the inner wall of the base 120. A sliding rod 360 is fixed in the fixing groove 350. Two groups of sliders 380 are slidably connected to the outer surface of the sliding rod 360, and a third spring 370 is fixed to one side of the slider 380. A fixing seat 320 is provided between the telescopic columns 330 and above the fixing groove 350, and the fixing seat 320 is fixedly connected to the lower surface of the compression plate 310. A connecting rod 340 is hinged at the bottom of the compression plate 310, and the other end of the connecting rod 340 is hinged to the slider 380. The two ends of the third spring 370 are respectively fixed to the inner surface of the two groups of sliders 380, and the third spring 370 is sleeved on the outer surface of the sliding rod 360.

[0030] When the mounting seat 110 is subjected to force, the compression plate 310 inside the base 120 is driven to move downward and squeeze the telescopic column 330, and then the compression plate 310 drives the fixing seat 320 below to move, and the fixing seat 320 drives the connecting rod 340 to move, and the connecting rod 340 drives the slider 380 to slide on the slide rod 360 and squeeze the third spring 370 on the outer surface of the slide rod 360, so as to obtain sufficient buffering, thereby improving the shock absorption effect and extending the service life of the butterfly valve.

[0031] When in use, when it is necessary to dock the valve body 100 with the pipe body 140, the alignment plate 2970 of the pipe body 140 is aligned with the mounting hole 2940 until the alignment plate 2970 completely enters the mounting hole 2940, and the moving ring 210 is rotated to move the moving ring 210 to the right, and then the moving ring 210 drives the fixing rod 230 to penetrate the inside of the penetrating ring 220 and enter the inside of the second fixing ring 2980. When entering the inside of the second fixing ring 2980, the fixing rod 230 is inclined. The inclined surface of the inclined block 240 is pressed against the inclined surface of the inclined block 240, driving the inclined block 240 to press the first spring 250, and causing the inclined block 240 to move toward the inside of the limiting groove 260 until the fixing rod 230 is completely inserted, and the first spring 250 restores its elastic deformation to drive the inclined block 240 to be stuck on the back side of the hook head of the fixing rod 230, thereby completing the installation. When it is necessary to disassemble, the rotating ring 290 is rotated, and then the rotating ring 290 drives the connecting rope 270. Since the installation ring 280 has a fixed pulley inside, the connecting rope 270 is effectively disassembled. The invention has a guiding function and reduces friction. When the rotating ring 290 rotates, it drives the connecting rope 270, and then the connecting rope 270 drives the inclined block 240 to move toward the inside of the limiting groove 260, thereby releasing the fixation of the fixed rod 230. When the rotating ring 290 is rotated, the rotating ring 290 simultaneously drives the extension ring 2910 to rotate inside the first fixed ring 2920 and drives the torsion spring 2930 to rotate, and the torsion spring 2930 achieves the function of automatic reset, thereby completing the disassembly, the operation is simple, and the disassembly and assembly efficiency is improved. When the mounting seat 110 is subjected to force, the compression plate 310 inside the base 120 is driven to move downward and squeeze the telescopic column 330, and then the fixed seat 320 below is driven to move by the compression plate 310, and the fixed seat 320 drives the connecting rod 340 to move, and the connecting rod 340 drives the slider 380 to slide on the slide rod 360 and squeeze the third spring 370 on the outer surface of the slide rod 360, thereby obtaining sufficient buffering, thereby improving the shock absorption effect and extending the service life of the butterfly valve.
