Description

Technical Field

[0001] The utility model relates to the technical field of valve body polishing, in particular to a valve body polishing device for valve processing. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. The valve body is a major component in the valve. During the valve processing, a polishing device is required to polish the outer surface of the valve body to improve the aesthetics of the valve.

[0003] Publication number "CN221065819U" provides a valve body surface polishing device, a valve body polishing device for a stop valve, which is provided with a dust hood, a connecting pipe, a dust pipe, a vacuum pump and a dust suction bin. When the valve body of the stop valve is polished, a large amount of debris will be generated, and the flying iron chips will cause pollution to the working environment. By driving the vacuum pump, the iron chips generated during polishing are adsorbed from the dust hood into the connecting pipe and the dust pipe, and finally sucked into the dust suction bin through the vacuum pump. Such a setting facilitates the unified collection of debris during the polishing process, thereby saving time and effort in cleaning up the debris, avoiding pollution of the working environment by the debris, and reducing the labor burden of the cleaning workers.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] First, the polishing device can only polish one valve body at a time, and can only polish one side of the valve body at a time during the polishing process. However, when the other side of the valve body needs to be polished, the clamping block needs to be loosened before the valve body can be turned over. The polishing efficiency needs to be improved. Secondly, the polishing device needs to start the vacuum pump to absorb the iron filings or dust generated during the polishing process. The working vacuum pump will increase the power consumption of the polishing device, and the energy saving efficiency needs to be improved. Utility Model Content

The pulling handle makes it convenient for the staff to pull and disassemble the collection box 713.

[0036] Working principle: During the valve processing, it is necessary to polish the outer surface of the valve body 4 to be polished. The staff first starts the driving motor 55, so that the driving motor 55 drives the first polishing wheel 59 to rotate through the active support shaft 58. At the same time, the active support shaft 58 will drive the driven support shaft 52 to rotate together through the first active pulley 56, the first transmission belt 57 and the first driven pulley 53, and the driven support shaft 52 will drive the second polishing wheel 51 to rotate, so that two staff members can use the rotating first polishing wheel 59 and the second polishing wheel 51 to take the valve body 4 to be polished for double-station polishing, thereby improving the polishing efficiency of the valve body 4 to be polished; at the same time, the active support shaft 58 will also drive the second active pulley 76 to rotate, so that the second active pulley 76 drives the driven shaft 79 to rotate through the second transmission belt 77 and the second driven pulley 78, and the driven The shaft 79 will drive the suction fan blades 712 to rotate. At this time, the rotating suction fan blades 712 will blow air toward the rear side and generate negative pressure on the front side of the exhaust pipe 74, so that the exhaust pipe 74 can suck the dust generated during the external polishing process through the connecting cavity 61 and the dust suction shell 72. The dust sucked into the dust suction shell 72 will first be coarsely filtered by the primary filter plate 73, and then will be blown into the dust removal filter bag 75 for further fine filtration. Finally, the filtered air will be discharged to the outside, thereby preventing the dust generated during the polishing process from not being handled in time and harming the respiratory health of the staff. Most of the debris generated during the polishing process will pass through the protective mesh plate 71 and the guide cavity 31 and fall into the collection box 713, so that the staff can concentrate on cleaning the debris later. When the polishing work is completed, the staff only needs to turn off the drive motor 55.
