Bidirectional seal pipeline butt joint

Abstract

The invention relates to a two-way sealed pipeline butt joint, which includes a connecting cylinder, and pressing rings are symmetrically arranged on both axial sides of the connecting cylinder, and an annular connecting ring is arranged on the outer ring of the tightening ring, and the connecting ring and the outer wall of the connecting cylinder pass through Threaded fixed connection; a pipe fixing assembly and a pipe sealing assembly are arranged between the connecting cylinder and the pressing ring; the pipe sealing assembly includes a pipe wall sealing ring and a compression ring, the compression ring is slidingly connected to the inner wall of the connection ring, and the pipe wall The sealing ring is clamped between the end of the connecting cylinder and the end of the compression ring; the pipe fixing component includes a ring-shaped spring leaf, the spring leaf is a tapered structure, and an annular support protrusion is arranged on the outer edge of the pressing ring. On the inner edge of the pressing ring, there is an annular pushing protrusion, and the spring piece is clamped between the supporting protrusion and the pushing protrusion; the inner wall of the middle part of the connecting cylinder is also provided with an annular pipe end sealing ring, and the pipe Annular sealing grooves are coaxially arranged at both lateral ends of the end sealing ring.

Description

technical field [0001] The invention relates to a two-way sealed pipeline butt joint, which belongs to the field of pipeline connectors. Background technique [0002] As a connection mechanism that connects pipes to some equipment or intermediate connectors, pipe joints have higher requirements for sealing performance after connection. In order to adapt to some pipes that need to be disassembled frequently, there is also a quick-connect pipe Joints, which mainly pass through a compression ring, squeeze the annular rubber ring through the compression ring, and use the extrusion deformation of the rubber ring to achieve the seal between the pipe and the joint, but in order to ensure good sealing performance, the rubber ring is required. The amount of deformation is large, and excessive extrusion can easily break the rubber ring, and when the pipe is inserted, it is easy to damage the inner wall of the rubber ring, which seriously affects the sealing effect of the pipe.
