卡套式管接頭介紹

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)用于各類機(jī)械的液壓、氣動系統(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：1)具有 24錐孔的接頭體。2)帶有尖銳內(nèi)刃的卡套3)起壓緊作用的螺母。旋緊螺母時， 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

2、接觸密封。同時卡套在內(nèi)刃口嵌入管子的外壁，在外壁上壓出一個環(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，卡套尾部也徑向收縮而抱住管子。參見下圖?？ㄌ资焦芙宇^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)中壓級時推薦用密封墊圈( JB1002-77)，高壓時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：卡套式管接頭共有 29 種品種，配用外徑 4m/m至 42m/m17種無縫鋼管或銅管，共計有 1364 種產(chǎn)品，詳見目錄。產(chǎn)品代號含義：5、訂貨須知：(1)用戶根據(jù) G

3、B標(biāo)準(zhǔn)或 JB 標(biāo)準(zhǔn)或有關(guān)規(guī)格參數(shù)從目錄中查到 KT- ，依照相應(yīng) 頁碼可知所需產(chǎn)品代號及該產(chǎn)品的有關(guān)技術(shù)數(shù)據(jù)。2)按 GB標(biāo)準(zhǔn)生產(chǎn)的卡套式管接頭接頭體材料為 35 鑄鋼。本廠還生產(chǎn) H62銅材料的各種卡套式管接頭。其外形尺寸與 GB標(biāo)準(zhǔn)相同，工作壓力 16Mpa，用戶采用訂貨 時在產(chǎn)品代號后加注“銅”字，例 KT7-9 銅，即為用 H62銅作材料的 Do=20的卡套式三通管接頭。3)表面處理一般為發(fā)黑，如需特殊表面處理(如鍍鉻)請訂貨時注明。卡套式端直通管接頭 GB 3733.1-83(JB1942-77)標(biāo)記示例:公稱壓力 J級, 管子外徑D0 為 14mm的卡套式端直通管接頭管接頭 J1
