Description

Technical field:

[0001] The invention relates to a connecting flange, in particular to a connecting flange for an air pipe valve part. Background technique:

[0002] With the development of urban modernization, there are many high-rise buildings everywhere, the reappearance of business centers, the networking of hypermarkets, etc., in order to further improve the quality of indoor ambient air and protect human health, so with the improvement of corresponding supporting facilities, especially Especially the central air-conditioning air duct system has been widely used. However, the currently used air duct system has heavy and complicated operations in processing and assembly, especially in the process of hoisting, often encountering surrounding Environmental barriers make construction difficult. Therefore, it is necessary to use space-consuming and heavy brackets. This will not only consume a lot of metal materials, but also reduce the progress of the work, and affect the com...
