DEVICE FOR CONNECTING AND DISCONNECTING PIPELINE OF THE DEVICE Russian patent published in 2017 - IPC F16L37/38 

FIELD: machine engineering.

SUBSTANCE: device comprises a board and detachable plates disposed in the pipe side plate shutoff valve configured as a seat with a central symmetrical bridge and two half-disks, cooperating with springs and provided with the inner and outer cantilevers with holes, and mounted at one end in the sleeve a spring-loaded rod with an adjustable tip. Inner shells are formed on one of the half-disks and the outside - on the second. Inner and outer half-disks consoles are installed in pairs by means of rollers arranged in their bores and placed on the lintel. Roller axis are disposed in a plane of symmetry of the bridge. On each half-disk between the inner lugs of one of them, the two brackets with pads are located, pro roller axis in the opposite direction of interaction places brackets with half-disks. Rod free end is mounted in the central opening and is provided with the bridge abutments, adapted to simultaneously interact with the roller brackets pro-axis platforms at the same distance from the plane of symmetry of the jumpers for the displacement and subsequent fixing brackets with half-disks. Thus console brackets and their points of interaction with the abutments contact pads of the same half-disks are located together at the same distance from a plane perpendicular to the plane of symmetry passing through the bridge and the valve axis. One end of the rod and a socket contacting with them are formed with profiled section. The ends of the stops are spherical.

EFFECT: invention improves the connection reliability and reduces the flow resistance.
