卡套式管接头介绍

1、卡套式管接头1、卡套式管接头用途：卡套式管接头适用于油、气、水为介质的管路系统。适用压力范围：(G)25Mpa,(J)40Mpa。2、卡套式管接头特点：卡套式管接头具有结构先进、性能良好、使用方便、不用焊接、不必将配管扩口，等一系列优点。因此，卡套式接头已广泛应用于各类机械的液压、气动系统中，但卡套式管接头的卡套制造精度较高，由于工艺复杂，不宜零星或小批制造，需专业生产。3、卡套式管接头结构与工作原理：卡套式管接头主要包括三部分：(1)具有24°锥孔的接头体。(2)带有尖锐内刃的卡套(3)起压紧作用的螺母。旋紧螺母时，卡套在压力下被推进24°锥孔。并随之下而变形，使卡套与接

2、头体内锥面形成球面接触密封。同时卡套在内刃口嵌入管子的外壁，在外壁上压出一个环形的闭口缘边，从而起到可靠的密封作用，卡套中部稍有拱形凸起，具有一定弹性，有利于密封和防止螺母松动，卡套尾部也径向收缩而抱住管子。参见下图。卡套式管接头采用公制细牙螺纹或锥螺纹与机件连接，且要采用密封垫圈，当中压级时推荐用密封垫圈(JB1002-77),高压时推荐用组合密封垫圈(JB982-77)或密封垫圈(JB1002-77)。4、卡套式管接头品种和产品代号:卡套式管接头共有29种品种，配用外径4m/m至42m/m17种无缝钢管或铜管，共计有1364种产品，详见目录产品代号含义:i规辂代号，壹装可知查目录可知S种代
