Description

Technical Field

[0001] This utility model belongs to the field of handwheel structure valve technology, and specifically relates to a marble handwheel structure. Background Technology

[0002] Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, and pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to the various valves used in highly complex automated control systems, with a wide variety of types and specifications. Valves can be used to control the flow of various types of fluids, including air, water, steam, various corrosive media, slurry, oil, liquid metals, and radioactive media.

[0003] A search revealed that in the prior art, Chinese Patent Publication No. CN219082408U, authorized on May 26, 2023, discloses a valve with a handwheel structure, including a valve body and a valve core.
