Problems solved by technology

In the actual application of this type of air valve, there are following deficiencies: 1. The gap leaks air
Even in today's market, the production cost and actual sales price of large air valves remain high; 4. The aesthetics are poor
Since the functional requirements of the louver damper determine the appearance of its device, even in an external location with a beautiful environment, the louver damper itself cannot change its appearance, and additional functional losses and economic costs will be added due to aesthetics. It is inevitable

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] refer to figure 2 , the curtain damper of the present invention, it comprises flexible curtain 30 and the driving device that drives its retractable movement, and the front side grille 21 that is fixedly arranged on flexible curtain 30 retractable movement plane two sides, rear side grille twenty two. The flexible curtain 30 can be retracted and retracted conveniently, changing the cross section of the flexible curtain 30 to block the ventilation pipeline, so that the ventilation pipeline is completely blocked or fully opened, or can be partially opened according to the demand to adjust the air flow through the pipeline , Compared with the traditional louver damper, it has good sealing performance. The front grille 21 and the rear grille 22 bear and decompose the pressure from the air valve pressurized entity. Since the flexible curtain 30 is...

Abstract

The invention relates to an air valve of a curtain, which has the advantages of good seal performance, simple structure as well as simpleness and convenience in control operation and can greatly reduce the production cost of the air valve. The air valve provided by the invention comprises a flexible curtain (30), a driving device, a front side grid (21) and a rear side grid (22), wherein the driving device drives the retraction motion of the flexible curtain (30); and the front side grid (21) and the rear side grid (22) are fixedly arranged at the two sides of the retraction motion plane of the flexible curtain (30).

Description

technical field [0001] The invention relates to an air duct valve for controlling and adjusting the airflow of a ventilation pipeline. Background technique [0002] The air duct valve is a commonly used device in various ventilation pipelines. Its basic function is to completely block or completely open the ventilation pipeline according to the actual needs of the ventilation system, and it can also be partially opened according to the demand to adjust the pipeline. Air flow through. At present, the most common form of this damper is the louver damper. The basic function of closing, opening or partially opening the ventilation pipeline is realized by the synchronous rotation of multiple sets of blades at different angles. In the practical application of this type of air valve, there are following deficiencies: 1. Air leakage through the gap. Since the louver air valve is composed of multiple sets of blades, when the air valve is closed, objectively there must be incomplete...
