高压密封接头系采用过盈锥度密封和机械连挂机构所组成的纯机械性结构型式。如图所示,本接头主要由母锥体,外箍和公锥体所组成。公母锥体分别通过支口与被连接管焊牢。母锥体的外沿有三个对称分布的凸爪,凸爪左端面上各有一条行程为10～15mm的螺旋面,外箍的左端面上有三个对称分布的凹口。安装时,使公母锥体上的三个凸爪和凹口对正插入(因外箍可自由旋转,故很容易对正),将外箍3转动一个小角度(约45°左右),使外箍凹口的侧面同凸爪左端面的螺旋面作用,迫使公锥体向左移动10～15mm,使公母锥体的锥面稍有过盈的紧密配合而达密封之效。本接头有以下优点:
High-pressure sealed connector system using the interference taper seal and mechanical linked to the mechanism consisting of purely mechanical structure type. As shown in the figure, the connector is mainly composed of a female cone, an outer hoop and a male cone. The male and female cones are welded to the pipe to be connected through the branch ports, respectively. The outer cone of the female cone has three symmetrically distributed claws. Each of the left claws has a spiral surface of 10-15 mm in its length and three symmetrically distributed notches on the left end of the outer band. Installation, so that the male and female cones on the three claws and notches inserted into the (because the outer hoop is free to rotate, it is easy to align), the outer hoop 3 rotates a small angle (about 45 ° or so) So that the side surface of the outer hoop notch with the left side of the face of the helical role of the helix, forcing the male cone to move to the left 10 ~ 15mm, so that the male and female cone cone slightly tight interference and seal effect. This connector has the following advantages:
