Description

Technical Field

[0001] The utility model relates to the technical field of pickling, and more specifically to a valve casting pickling device. Background Art

[0002] Valves are control components in fluid delivery systems, with functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief. They 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 pickling of valve castings is to immerse the entire valve in the pickling liquid until the surface of the valve presents a uniform silver-white color, then take out the workpiece and rinse the surface with clean water.

[0003] The existing valve casting pickling adopts traditional manual operation, which requires workers to hold the metal mesh frame to remove the pickling liquid, which is not safe and easily causes the metal mesh frame to fall and the pickling liquid to splash, making it inconvenient to use at work.
