Novel remote adjusting device for concealed air valve

Abstract

The invention discloses a novel remote adjusting device for a concealed air valve. The novel remote adjusting device comprises an executing mechanism, an operating mechanism and a flexible transmission assembly. The device has the beneficial effects that reliable adjustment of the ventilation pipeline air valve at the far end can be achieved through the device, the number of air valve service ports in a suspended ceiling is reduced, the overall installation quality of the suspended ceiling is improved, the device is particularly suitable for being used as an air valve in a theme carving suspended ceiling in a theme park project, and meanwhile the service life of the air valve is prolonged. The adjusting mechanism of the air valve is arranged at a position convenient to operate, so that the subsequent operation and use of the property are facilitated; the device is low in manufacturing cost, quick to mount, high in field adaptability, low in technical requirement on workers, economical, practical, stable and reliable in mechanism, high in construction efficiency and good in survival effect.

Description

technical field [0001] The invention relates to a damper adjustment device, in particular to a novel concealed damper remote adjustment device, which belongs to the technical field of building construction. Background technique [0002] The air valve is an indispensable central air-conditioning terminal fitting 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 branch pipes. The traditional adjustment of air valves is often used. On-site manual adjustment of the air valve or the adjustment scheme of the air valve electric adjustment mechanism. [0003] The scheme of using on-site air valve adjustment needs to open an inspection port for personnel to operate on the ceiling directly below the air valve. The operator needs to drill into the ceiling to manually adjust the air valve. Because the high-altitude operation increas...

AI Technical Summary

Problems solved by technology

[0003] The scheme of using on-site air valve adjustment needs to open an inspection port for personnel to operate on the ceiling directly below the air valve. The operator needs to drill into the ceiling to manually adjust the air valve. Because the high-altitude operation increases the danger of the operator, And it is not conducive to the protection of finished products, and because the conventional size of the inspection port is 450mm×450mm, the overall visual quality of the suspended ceiling is deteriorated

[0004] The scheme of adopting the air valve electric adjustment mechanism avoids the high-altitude operation of daily operators during the adjustment process of the air valve. However, due to the high construction cost of the air valve electric adjustment mechanism, and the adjustment of the air valve often requires opening adjustment, an analog The air valve with volume adjustment realizes the function, while the cost of the analog air valve is more expensive, and the failure rate of the weak current control system is high. Accessible inspection ports must be set on the ceiling, which also deteriorates the overall visual quality of the ceiling.
