Description
Technical Field
[0001] The invention relates to the technical field of gas ball valves, and in particular to a valve body surface treatment and deburring device for processing a gas ball valve. Background Art
[0002] Gas ball valve is a control valve used in gas system. It uses a ball as the opening and closing part. The ball rotates around the axis perpendicular to the pipeline axis to realize opening and closing. The valve body is usually made of cast steel, stainless steel and other materials. It has good sealing performance and can effectively prevent gas leakage to ensure safe use. It has the advantages of simple structure, small size, light weight, small fluid resistance, fast opening and closing, convenient operation and easy maintenance. It is widely used in urban gas transmission and distribution pipelines, industrial gas application sites, household gas facilities and other fields; The gas ball valve body is a key component of the gas ball valve. It is usually made of high-quality materials such as cast steel, stainless steel or copper alloy. It has good strength, corrosion resistance and pressure resistance, and can withstand the pressure and harsh environment during gas transportation. Its shape is mostly spherical or cylindrical, and the internal design has a channel that matches the ball to ensure smooth passage of gas. The structural design of the valve body must ensure sealing, and closely cooperate with the ball, valve seat and other components to prevent gas leakage and ensure safe use. Therefore, the surface of the valve body needs to be polished and deburred; Grinding and deburring the gas ball valve body is a key process to ensure its quality and performance. After the valve body is processed and manufactured, burrs often appear on the surface and edges. These burrs not only affect the appearance, but are also likely to scratch the seals during use, leading to gas leakage. Grinding and deburring generally uses mechanical grinding such as belt grinding machines, polishing machines, etc., and uses abrasives to grind the valve body surface to remove burrs. The grinding process requires strict control of force and direction to ensure that the valve body dimensional accuracy and surface roughness meet the requirements, ensuring that the gas ball valve is safe, reliable and well sealed in subsequent use. When existing grinding equipment is grinding, grinding chips usually remain on the valve body surface, and some large particles of chips may scratch the valve body surface, so we proposed a valve body surface treatment and deburring equipment for gas ball valve processing.
