[0002] Valves are control components in fluid conveying systems, with functions such as shutoff, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Valves used in fluid control systems, from the simplest shut-off valves to various valves used in extremely complex automatic control systems, have a wide variety of varieties and specifications. 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. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves, chrome-molybdenum steel valves, chrome-molybdenum-vanadium steel valves, duplex steel valves, plastic valves, non-standard customized valves, etc. according to their materials. The valve plate is the core component of the valve, which plays a vital role in the use of the valve. The valve plate needs to be ground during the production and processing process.

It is also prone to problems such as omissions and uneven grinding, resulting in incomplete grinding and poor grinding quality. At the same time, the product position needs to be frequently adjusted during the grinding process, making the overall operation very troublesome and increasing labor intensity.

A driving motor 1 is provided on the top of the grinding frame 3, and the output end of the driving motor 1 passes through the grinding frame 3 and is provided with a rotating shaft 2. The bottom end of the rotating shaft 2 is movably provided with a universal connecting rod 4, which is driven by the driving motor 1 to rotate the rotating shaft 2, and the rotating shaft 2 drives the universal connecting rod 4 to change in different directions, thereby driving the grinding head 6 to shake and rotate in different directions, and the valve plate 7 is covered by the grinding head 6, so that the shaking and rotating process of the grinding head can rub against the outer surface of the valve plate 7 to achieve grinding, making the overall grinding more comprehensive, and effectively improving In order to improve the overall efficiency and quality of grinding, a transverse connecting strip 5 is provided at the bottom end of the universal connecting rod 4, and a grinding head 6 is provided at the bottom of the transverse connecting strip 5. A valve plate 7 is provided correspondingly below the grinding head 6. The grinding head 6 and the valve plate 7 are mutually covered and ground, which replaces the traditional grinding head method of grinding the valve plate in different positions, avoiding the need to frequently change the orientation or flip the valve plate, making the operation more convenient as a whole, and greatly reducing the labor intensity. Clamping seats 8 are slidably provided on both sides of the top of the adjustment base 10, and adjusting rods 9 are provided on both sides of the bottom of the clamping seat 8.
