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：具有24锥孔的接头体。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，使卡套与接头体内锥面形成球面接触密封。同时卡套

2、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。1-組含垫圈援头3-卡套丁蛭母才配直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：KT79解释:.m-g踰压力宓，d
