1、卡套式管接頭1卡套式管接頭用途：卡套式管接頭適用于油、氣、水為介質(zhì)的管路系統(tǒng)。適用壓力范圍：(G)25Mpa，(J)40Mpa。2、卡套式管接頭特點(diǎn)：卡套式管接頭具有結(jié)構(gòu)先進(jìn)、性能良好、使用方便、不用焊接、不必將配管擴(kuò)口，等一系列優(yōu)點(diǎn)。因此，卡套式接頭已廣泛應(yīng)用于各類(lèi)機(jī)械的液壓、氣動(dòng)系統(tǒng)中，但卡套式管接頭的卡套制造精度較高，由于工藝復(fù)雜，不宜零星或小批制造，需專(zhuān)業(yè)生產(chǎn)。3、卡套式管接頭結(jié)構(gòu)與工作原理：卡套式管接頭主要包括三部分：具有24錐孔的接頭體。帶有尖銳內(nèi)刃的卡套(3)起壓緊作用的螺母。旋緊螺母時(shí)，卡套在壓力下被推進(jìn)24。錐孔。并隨之下而變形，使卡套與接頭體內(nèi)錐面形成球面接觸密封。同時(shí)卡套

2、在內(nèi)刃口嵌入管子的外壁，在外壁上壓出一個(gè)環(huán)形的閉口緣邊,從而起到可靠的密封作用，卡套中部稍有拱形凸起，具有一定彈性，有利于密封和防止螺母松動(dòng)，卡套尾部也徑向收縮而抱住管子。參見(jiàn)下圖。1-組含墊圈援頭3-卡套丁蛭母才配直卡套式管接頭采用公制細(xì)牙螺紋或錐螺紋與機(jī)件連接，且要采用密封墊圈,當(dāng)中壓級(jí)時(shí)推薦用密封墊圈(JB1002-77)，高壓時(shí)推薦用組合密封墊圈(JB982-77)或密封墊圈(JB1002-77)。4、卡套式管接頭品種和產(chǎn)品代號(hào):卡套式管接頭共有29種品種，配用外徑4m/m至42m/m17種無(wú)縫鋼管或銅管，共計(jì)有1364種產(chǎn)品，詳見(jiàn)目錄。產(chǎn)品代號(hào)含義：KT79解釋:.m-g踰壓力宓，d
