根据JB1942—77～1989—77标准制定的卡套管接头,是一种先进的新型管路连接结构,用在液压管路中,避免了焊接式管接头具有的焊渣和夹杂对油路的污染,因而引起广泛的重视。国外已普遍用于各种液压管路中。我厂从一九七六年起,在生产的铸工造型自动线管路上,全部采用了直径10～42毫米无缝钢管的卡套管接头。考虑到所用卡套规格数量很多,又吸取了兄弟厂使用的经验教训,我们着重于卡套接头的预装工作,并根据生产需要,初步制订了卡套接头预装工
According to JB1942-77 ~ 1989-77 standard developed by the tube fittings, is an advanced new pipeline connection structure, used in the hydraulic pipe, welded joints to avoid welding slag and inclusions on the oil road Pollution, which caused widespread attention. Foreign countries have been widely used in a variety of hydraulic pipelines. I plant from 1976 onwards, in the production of cast molding automatic line line, all with a diameter of 10 to 42 mm seamless steel pipe fittings. Taking into account the large number of sleeve specifications used, but also learned the experience of brothers plant used, we focus on the pre-card connector joints work, and according to production needs, pre-developed card connector pre-installed workers
