[0002] Valves are piping accessories used to open and close pipelines, control flow direction, and regulate and control the parameters of the conveyed media. Based on their function, they can be categorized as shutoff valves, check valves, and regulating valves. Valves are control components in fluid conveying systems, performing functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion, and overflow pressure relief. Valves used in fluid control systems come in a wide variety of types and specifications, from simple globe valves to highly complex automatic control systems. Valves can be used to control the flow of various fluids, including air, water, steam, various corrosive media, slurries, oils, liquid metals, and radioactive media. Valves are also categorized by material, including cast iron valves, cast steel valves, stainless steel valves (such as 201, 304, and 316), chrome-molybdenum steel valves, chrome-molybdenum-vanadium steel valves, duplex steel valves, plastic valves, and custom valves.

The connecting cartridge 2 68 has a recessed portion and an internal thread is provided on the recessed portion for use with the external thread. The connecting cartridge 1 67 and the connecting cartridge 2 68 are used in conjunction with the external thread and the internal thread, which is convenient for disassembly and assembly, and thus convenient for cleaning the collecting net cartridge 69. The collecting net cartridge 69 can be used to filter the refluxed water and collect debris, thereby ensuring the smooth use of water circulation.

[0065] The working method of the present invention is as follows: first, the position of the two workpiece tighteners 5 is adjusted according to the specification length of the workpiece to be supplied. During the adjustment, the trapezoidal insertion rod 22 is pulled so that the trapezoidal insertion rod 22 disengages the slot on the operating disc 20 and stretches the spring 23. The operating disc 20 is rotated to drive the worm 12 to rotate. The worm 12 and the worm gear 14 are used in conjunction to make the rotating shaft 13 drive the elliptical disc 15 to rotate, and then the sliding plates 17 on both sides are driven to move relative to each other under the hinged action of the elliptical disc 15 and the articulated arm 16, thereby driving the side plates 3 on both sides to move relative to each other through the connecting plate 19, so that the position of the workpiece tighteners 5 on both sides can be adjusted. After the workpiece is placed, the two workpiece tighteners 5 can be inserted into the two ends of the workpiece, and the rotation of the operating disc is stopped. Disc 20, loosen the trapezoidal insertion rod 1 22 and use the elasticity of spring 1 23 to drive the trapezoidal insertion rod 1 22 to insert into the slot on the operating disc 20, which can lock the operating disc 20. At this time, the spring 2 41 on the trapezoidal insertion rod 2 39 is squeezed to generate a downward force so that the polishing machine 42 is close to the surface of the workpiece, and then start the motor 26, and use the motor 26 to drive the screw 28 to rotate through the rotating shaft 25, driving the moving block 27 to move, and then under the hinged action of the articulated arm 29, the two inner tightening plates 30 are driven to move outward, thereby effectively tightening the inner wall of the workpiece, and then the polishing distance limiters 9 on both sides are adjusted according to the length specifications of the workpiece. When adjusting, pull the operating plate 50 upward, and the operating plate 50 drives the sliding rod 49 to move. , the sliding rod 49 drives the card block 51 to disengage from the card slot and squeeze the spring three 52 to contract, holding the sliding frame 46 to slide through the guide bar 1 45, and releasing the operating plate 50 after sliding to the appropriate position. The elasticity of the spring three 52 drives the card block 51 to reset and insert it into the relative card slot to complete the adjustment, and then start the motor 56 and the water pump 61. The motor 56 drives the gear one 57 to rotate and drives the rotating drum 53 to rotate under the meshing action of the gear one 57 and the gear two 58. Under the action of the guide bar two 55, the rotating shaft four 54 follows the rotating drum 53 to rotate, and the rotating shaft four 54 drives the workpiece tightener 5 to rotate, and then drives the workpiece to rotate. At the same time, when the rotating drum 53 rotates, it drives the rotating shaft three 36 to rotate under the action of the pulley 59 and the belt, and the rotating shaft three 36 drives the screw 37 to rotate to drive the moving drum 53. The movable plate 38 drives the polishing machine 42 to move, and when the movable plate 38 moves, it drives the resistance rod 44 to move through the connecting frame 43. When the resistance rod 44 touches the contact switch 47, the contact switch 47 controls the motor 56 to reverse, thereby realizing the back and forth movement of the polishing machine 42, thereby realizing the comprehensive polishing operation of the workpiece. At the same time, during the polishing process, the water in the water tank 60 is extracted by the water pump 61 through the filter cartridge 62 and the water pipe 1 63, and is transported to the water outlet nozzle 65 through the water pipe 2 64 to be sprayed, thereby spraying water to cool the polishing position to prevent the polishing machine 42 from overheating and burning, and the debris generated by polishing can be flushed. The flushed water flows back to the water tank 60 through the return pipe 66 and is repeatedly extracted, and is filtered and collected by the collection net cylinder 69.When cleaning is required, twist the connecting tube 1 67 and the connecting tube 2 68 to separate them, remove the collecting net tube 69 and clean it.
