Description

Technical Field

[0001] This utility model relates to the field of butterfly valve technology, and more specifically, to a shockproof butterfly valve that is easy to maintain. Background Technology

[0002] A butterfly valve, also known as a flap valve, is a simple regulating valve used for on / off control of low-pressure pipeline media. A butterfly valve is a type of valve where the closing element is a disc that rotates around a valve shaft to open and close. These valves can control the flow of various types of fluids, including air, water, steam, various corrosive media, mud, 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. Currently, existing butterfly valves are inconvenient for workers to disassemble and maintain during use, and shock absorption and protection are not available. Utility Model Content

A damper 2 is fixedly connected to the upper surface of the fixed platform 1. By setting the damper 2, a first magnet 27, and a second magnet 28, the damper 2, the first magnet 27, and the second magnet 28 can buffer the impact force on the mounting plate 4 from the outside, achieving the effect of shock absorption and protection for the butterfly valve body 24. The top of the damper 2 is fixedly connected to the mounting plate 4, and the upper surface of the mounting plate 4 is fixedly connected to the fixed plate 6. An electric push rod 7 is fixedly connected to the surface of the fixed plate 6. One end of the electric push rod 7 is fixedly connected to the support plate 5. The surface of the support plate 5 is fixedly connected to the protective shell 8, and the inside of the protective shell 8 is fixedly connected to the forward and reverse motor 9. By setting the electric push rod 7 and the forward and reverse motor 9, the mounting frame 21 that moves to the surface of the mounting plate 4 can be disengaged from the positioning post 18 by simply starting the electric push rod 7 and the forward and reverse motor 9 through the control switch 3, making it convenient for the staff to disassemble and maintain the butterfly valve body 24. The output shaft of the machine 9 is fixedly connected to a first rotating shaft 10. A transmission worm gear 11 is fixedly connected to the surface of the first rotating shaft 10. A bearing is fixedly connected inside the protective shell 8 so that a second rotating shaft 12 passes through it. A transmission worm wheel 13 is fixedly connected to the surface of the second rotating shaft 12. The transmission worm gear 11 and the transmission worm wheel 13 mesh with each other. A mounting groove 15 is opened on the surface of the support plate 5. A rotating disk 14 is arranged inside the mounting groove 15. One end of the second rotating shaft 12 is fixedly connected to the surface of the rotating disk 14. A positioning post 18 is fixedly connected to the surface of the rotating disk 14. A mounting frame 21 is provided on the upper surface of the mounting plate 4. A limit groove 22 is fixedly connected to the surface of the mounting frame 21. The positioning post 18 passes through the inside of the limit groove 22. A fixing frame 23 is fixedly connected to the upper surface of the mounting frame 21. A butterfly valve body 24 is fixedly connected inside the fixing frame 23. A connecting flange 25 is fixedly connected to one end of the butterfly valve body 24. A first magnet 27 is fixedly connected to the lower surface of the mounting plate 4. A second magnet 28 is fixedly connected to the upper surface of the fixing platform 1.

[0027] Specifically, there are multiple dampers 2, which are evenly arranged on the upper surface of the fixed platform 1. The first magnet 27 is located directly above the second magnet 28, and the bottom end of the first magnet 27 and the top end of the second magnet 28 have the same magnetic poles.

[0028] Specifically, the inside of the mounting groove 15 and the surface of the rotating disk 14 are both provided with a first sliding groove 17. The first sliding groove 17 is circular, and a ball bearing 16 is movably connected inside the first sliding groove 17. There are multiple balls bearing 16, which are evenly arranged inside the first sliding groove 17.

[0029] Specifically, a slider 19 is fixedly connected to the lower surface of the support plate 5, and a second groove 20 is provided on the upper surface of the mounting plate 4. The slider 19 is movably connected inside the second groove 20. There are two sets of sliders 19 and two grooves 20, which are symmetrically arranged on the upper surface of the mounting plate 4.

[0030] By adopting the above technical solution, with the cooperation of the second slide groove 20 and the slider 19, the electric push rod 7 can drive the support plate 5 to move in a directional manner on the upper surface of the mounting plate 4, thus avoiding the support plate 5 from shifting during the movement.

[0033] The working principle of this utility model is as follows: When using this utility model, firstly, the device is moved to a suitable position, and then the position of the fixing platform 1 is fixed by the fixing bolts 30, thereby preventing the device from shifting during use. When the operator uses this device to maintain the butterfly valve, firstly, the operator starts the forward and reverse motor 9 by controlling the switch 3. Simultaneously, the forward and reverse motor 9 drives the transmission worm gear 11 to rotate via the first rotating shaft 10. Then, the transmission worm gear 11 drives the second rotating shaft 12 to rotate via the transmission worm wheel 13. The second rotating shaft 12 then drives the positioning pin 18 to rotate via the rotating disk 14, causing the positioning pin 18 to rotate. The limit groove 22 drives the pulley 26 on the lower surface of the mounting frame 21 to engage with the upper surface of the mounting plate 4. Then, the operator stops the forward and reverse motor 9 by controlling the switch 3, and the operator controls the electric push rod 7 to shorten by controlling the switch 3. At the same time, the electric push rod 7 drives the positioning post 18 on the surface of the rotating disk 14 to move through the support plate 5, so that the positioning post 18 moves out of the limit groove 22, which makes it easier for the operator to disassemble and maintain the butterfly valve body 24. In addition, with the cooperation of the damper 2, the first magnet 27 and the second magnet 28, the impact force on the mounting plate 4 from the outside can be buffered, thereby providing shock absorption protection for the butterfly valve body 24.
