Description

Technical Field

[0001] The utility model relates to the field of ball valve processing, in particular to a grinding device for processing stainless steel ball valves. Background Art

[0002] The main features of stainless steel ball valves are compact structure, easy operation and maintenance. Stainless steel ball valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media; the ball valve body can be integral or combined;

[0003] During the production process of stainless steel ball valves, the joints at both ends need to be polished to prevent the stainless steel ball valves from being unusable due to uneven joints during installation, resulting in large gaps. Most existing polishing devices directly fix the ball valve on a fixed surface for single-sided polishing. The waste chips generated during the polishing process will splash out and endanger the health of the operator. After polishing one end of the ball valve is completed, the conventional fixing device needs to first loosen the fixing device to flip the ball valve and then fix it, which makes the polishing time longer.

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content
