通风和空调工程通常需要使用一定数量的风口,是必不可少的配件。过去,由于风管的尺寸没有统一的标准,各设计单位所设计的风口规格繁多,无法采用机械成批预制加工,只能按工程的实际需要进行小批手工生产,随规格的不同逐个放样,手工落料,手工成型,施工方法十分落后,因此费工、费料、费力,而且交货周期长,工程安装进度慢。为了改变生产面貌,早日实现通风管道和配件标准化、工厂化、机械化施工,我队于1972年
Ventilation and air conditioning works usually require the use of a certain number of tuyere, is an essential accessory. In the past, there was no uniform standard for the size of the air duct. Each design unit designed many kinds of air vents and could not adopt mechanical batch prefabrication. Only small batch manual production can be carried out according to the actual needs of the project, Manual blanking, manual molding, construction methods are very backward, so labor, costly, laborious, and the delivery cycle is long, the progress of the installation of the project is slow. In order to change the production outlook, as soon as possible to achieve the standardization of ventilation pipes and fittings, factory, mechanized construction, our team in 1972
