FIELD: machine building.SUBSTANCE: connection includes a housing with an internal annular projection, in an axial channel of which a tip with an annular piston installed inside an annular chamber is installed. The annular chamber is formed with an internal annular projection of the housing and a connection element with a flange on the end with its separation into balancing and load-carrying chambers that are connected with radial holes in the housing body to atmosphere and in the tip body with its axial channel. The tip is equipped with a bearing arranged in the housing bore so that it is supported from its annular projection pressed to it with a nut connected to the housing internal thread. The tip is equipped with a connection element with a flange on the end, on which there is a thread and a lock nut is installed with a possibility of face contact to the nut. Annular gaps are covered with sealing rings. At installation of the device as a part of a pipeline, the lock nut is screwed as much as possible onto the connection element, and the tip is introduced as much as possible into the axial channel of the housing with reduction of a distance between the flanges.EFFECT: unrestricted introduction of a device between the mating flanges of a pipeline; improving the device operating reliability.2 dwg |
