Description

Technical Field

[0001] This utility model relates to the field of air valve technology, and more specifically, to a novel air valve control device. Background Technology

[0002] Air valves are devices used for ventilation and air conditioning in offshore production facilities in the oil and gas industry. They serve functions such as fire prevention, sealing, pressure release, and flue gas control. Air valves achieve their functions by opening and closing their blades.

[0003] In practical use, air valves are divided into two types: manual control and automatic control. Manual control relies on manual operation, while automatic control relies on complex control devices. Conventional air valve control devices are directly installed on the air valve body, forming the same device as the air valve. After installation, the air valve is opened and closed according to a set angle, but it is not possible to achieve both manual and automatic control at the same time. Utility Model Content
