Description

Technical Field

[0001] This utility model relates to the field of safety valve processing technology, and in particular to a safety valve body sealing surface grinding equipment. Background Technology

[0002] A safety valve is a special valve that is normally closed under external force. When the pressure of the medium in the equipment or pipeline rises above a specified value, it discharges the medium to the outside of the system to prevent the pressure of the medium in the pipeline or equipment from exceeding the specified value. Safety valves belong to the category of automatic valves and are mainly used in boilers, pressure vessels, and pipelines to control the pressure to not exceed the specified value. They play an important role in protecting personal safety and equipment operation. Note that safety valves must undergo pressure testing before use. At present, the sealing surface of safety valves is mostly ground manually by workers. Workers grind from coarse sandpaper to fine sandpaper. Due to the limitations of human structure and manual technique, manual grinding can only rotate a maximum of 1 / 4 turn each time while maintaining uniform and stable force, which is very inefficient. Secondly, as the grinding precision becomes higher and the roughness of the sealing surface becomes smaller, uneven force during manual grinding will cause the workpiece to vibrate during grinding, resulting in damage to the workpiece surface and rework. Therefore, we have proposed a safety valve body sealing surface grinding equipment. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a grinding device for the sealing surface of a safety valve body. This invention solves the current problem that safety valve sealing surfaces are mostly ground manually by workers. This involves workers gradually grinding from coarse sandpaper to fine sandpaper, but due to limitations in human structure and technique, manual grinding can only achieve a maximum rotation of 1 / 4 turn per pass while maintaining uniform and stable force, resulting in extremely low efficiency. Furthermore, as grinding precision increases and the surface roughness decreases, uneven force during manual grinding can cause the workpiece to vibrate, leading to damage and rework.
