CONNECTION OF MAIN AND LATERAL PIPELINES (VERSIONS)

摘要

FIELD: machine building. ^ SUBSTANCE: connection of main and lateral pipelines in heat systems consists of T-joint on main pipeline and of L-shaped tubular insertion. The side branch of the T-joint is perpendicular to the lateral pipeline. According to the first version the L-shaped insertion connects the side branch of the T-joint with the lateral pipeline. The distinguished feature of the claimed design of the first version is connection of the L-shaped insertion with the side branch of the T-joint by means of a hinge wherein axis of rotation coincides with axis of the branch. According to another version the lateral pipeline has a L-shaped tubular element wherein one axis is parallel to axis of the side branch of the T-joint, while a ""-shaped tubular insertion is installed between the branch of the T-joint and the L-shaped element of the lateral pipeline. The tubular insertion is connected to them by means of pivot connections with axes of rotation coinciding with axes of the side branch and L-shaped element. ^ EFFECT: increased reliability of pipelines connection. ^ 2 cl, 5 dwg
