Description

Technical Field

[0001] The utility model relates to the technical field of valve switch equipment, in particular to a switch device for a hand wheel type valve. Background Art

[0002] Handwheel valves are important control components in pipeline fluid delivery systems. They are used to change the passage section and the flow direction of the medium. They have functions such as diversion, cutoff, regulation, throttling, non-return, diversion or overflow pressure relief. Valves used for fluid control have nominal diameters ranging from extremely small instrument valves to industrial pipeline valves with a diameter of 10m. Handwheel valves rely on handwheels to drive the turbine-worm reduction mechanism to make the opening and closing parts move up and down, slide, swing or rotate, thereby changing the size of their flow area to achieve their control functions. Handwheel valves have simple structures, reliable mechanical structures, relatively low costs, and a very wide range of applications. They can play an important role in pipeline systems with different pressures, media, temperatures, and diameters.
