雙卡套式接頭的常規安裝步驟

發布時間:2020-05-30    字號:    
雙卡套式接頭的常規安裝步驟:
    1、將管子插入接頭,確保管子端部達到接頭底部,并用手指擰緊卡套螺母。 
    2、在卡套螺母的6點位置做一標記。
    3、用扳手固定接頭本體,旋轉卡套螺母一又四分之一轉,這時所做標記旋轉540度,至9點鐘位置。
    通過螺紋機械式推進,卡套螺母向前運動推動后卡套向前,同時后卡套推動前卡套向前運動;接頭本體的向內擠壓前卡套;前卡套去掉它的內徑與管子外徑間的公差;隨著后卡套的推進,前卡套向前向內動作,后端抬起,與接頭本體斜面形成密封;隨著管子更大的變形和本體斜面與前卡套接觸面的增大,更大的阻力迫使后卡套向內動作,從而在管子上形成二道牢固的支撐。
