Description

Technical Field

[0001] This invention relates to the field of valve maintenance technology, and in particular to a valve maintenance and disassembly device for thermal power plants. Background Technology

[0002] Valves are pipeline fittings used to regulate and control the flow of media, and they are often used to open and close pipelines and control the flow direction. They have many functions, and because valves are inconvenient to replace, it is necessary to ensure the sealing and robustness of each valve during production. Different media will cause different damage to valves during use. In order to ensure the service life of the valves, regular inspection is required to ensure the safety of the valves during use. However, most current dismantling equipment has a relatively simple structure. When using it, tools are usually required to assist the user in the dismantling work. Due to the simple structure of the dismantling equipment, it is usually not adjustable. When dismantling valves of different heights and angles, different tools need to be changed and different positions need to be moved to dismantle the valves, which takes more time. In addition, due to the long-term transportation of media, the surface of the valves will accumulate a lot of dirt, which will make the dismantling equipment prone to stripping during maintenance and dismantling work, making it difficult to apply torque. Special cleaning is required, which takes more time and delays the progress of the dismantling work. Therefore, we propose a valve maintenance and dismantling equipment for thermal power plants.

[0024] like Figure 1-6The connecting plate 1 shown is made of stainless steel and has a hollow interior. The inner wall thickness of the connecting plate 1 is greater than or equal to 0.5mm. The fixing plate 2 is welded to the connecting plate 1. Two fixing plates 2 are symmetrically installed to reduce weight and facilitate use. The first fixing knob 3 passes through the fixing plate 2 and the rotating plate 4 and is screwed on for secure fixation. The rotating plate 4 can rotate within the fixing plate 2. The rotating plate 4 is made of stainless steel and has a maximum rotation angle of less than or equal to 90°, increasing its selectable rotation angle. The second fixing knob 5 passes through the rotating plate 4 and the fixing hole 7 and is screwed on for secure fixation. The connecting rod 6 can rotate within the rotating plate 4. The connecting rod 6 is made of steel, and the sleeve 8 is welded to it. The sleeve 8, also made of steel, is highly durable and can support greater weight. The motor 9 is connected to the mounting rod 12. The fixing rod 10 is bolted to the sleeve 8. The mounting plate 11 is screwed and fixed to the fixing rod 10. The mounting rod 12 is rotatably connected to the mounting plate 11 via a rotating shaft 13. The disassembly plate 14 is bolted to the mounting rod 12. The bottom of the disassembly plate 14 has an adapter groove, which can be hexagonal or cross-shaped, increasing its adaptability to various disassembly shapes. Two sliding plates 15 are equidistantly installed and slidably connected to the connecting plate 1. The first adjusting knob 16 passes through the connecting plate 1 and the first positioning hole 17 and is screwed tight. Several first positioning holes 17 are evenly spaced. A fixing ring 18 is welded to the sliding plate 15 corresponding to the first adjusting knob 16. The fixing ring 18 is made of stainless steel and has a rubber ring installed on its inner side. The second adjusting knob 19 passes through the fixing ring 18 and the second positioning hole 21 and is screwed tight. The extension ring 20 is made of steel. One end of the extension ring 20 is welded to the fixing ring 18, and the other end passes through the fixing ring 18 and extends into it. One end of the extension ring 20 can slide within the fixing ring 18. The device is movable. Several second positioning holes 21 are equally spaced. The sleeve plate 22 is welded to the connecting plate 1. The third fixing knob 23 passes through the sleeve plate 22 and the third positioning hole 25 and is screwed tight. The support plate 24 can slide inside the sleeve plate 22. Several third positioning holes 25 are equally spaced. Several anti-slip pads 26 are equally spaced and are made of rubber.

The delivery pump 28 is connected to the descaling agent storage tank 27 and the nozzle 29 by pipe. Several nozzles 29 are equally spaced and are high-pressure nozzles.

[0025] The workflow of this invention is as follows: When using a valve maintenance and disassembly device for a thermal power plant to perform high-voltage power supply maintenance, firstly, the sliding plate 15 is pulled out from the connecting plate 1, so that the fixing ring 18 is located on both sides of the valve. Then, the extension ring 20 is pulled out from the fixing ring 18, and the fixing ring 18 is fixed to the pipeline through the extension ring 20. Then, the support plate 24 is pulled out and supported on the ground to fix the entire disassembly device. At this time, the delivery pump 28 is started to deliver descaling agent from the descaling agent storage tank 27 to the nozzle 29. The jet from the nozzle 29 cleans the dirt on the valve. After cleaning, the rotating plate 4 is rotated. Adjust its angle so that the mounting plate 11 falls on the valve's fixed point. Then start the motor 9 to drive the mounting rod 12 to rotate, thereby causing the disassembly plate 14 to rotate and the fixing bolts to be removed. During disassembly, the connecting rod 6 can be rotated simultaneously to adjust the elevation angle. Using this valve maintenance and disassembly equipment for thermal power plants for high-voltage power supply maintenance work increases the equipment's adjustability and the ease of replacing the disassembly structure, making it more convenient to use and saving the time required to replace different equipment. In addition, this equipment can more quickly descale the valve and reduce the impact of oil on the disassembly equipment.
