Description

Technical Field

[0001] The utility model relates to the technical field of air volume regulating valves, in particular to a high-efficiency transmission mechanism for dual-controlling air volume regulating valves. Background Art

[0002] The air volume regulating valve, also known as the damper, is an indispensable central air-conditioning terminal accessory in the ventilation, air conditioning and air purification projects of industrial plants and civil buildings. It is generally used in air-conditioning and ventilation system pipes to adjust the air volume of the branch pipes. It can also be used for the mixing adjustment of fresh air and return air. Its main characteristics are flexible operation, low noise and small leakage. When adjusting the flow and closure of the air volume regulating valve, an efficient transmission mechanism is used to achieve it.

[0003] When the existing high-efficiency transmission mechanism adjusts the flow and closure of the air volume control valve, it is often adjusted through the same structure, which can adjust both the flow and the closure. However, when the closing structure is damaged, the air volume control valve also loses the closing function accordingly. For the valve body, in order to meet higher requirements, in actual application, the valve body can not only be electrically controlled to close, but also can be manually closed when the electric control closure fails, so as to achieve a dual control effect. When the closing structure of the existing high-efficiency transmission mechanism is damaged, both adjustments fail, which brings inconvenience to people's use. A high-efficiency transmission mechanism for a dual-control air volume control valve is specifically introduced. Utility Model Content
