FIELD: machine building.SUBSTANCE: in a detachable connection consisting of a stationary socket piece and a replaceable socket piece with an end face sealing element in-between, a lock in the form of a collet sleeve with external and internal collar and a locking bush, the replaceable sealing socket piece is made of two parts: external and internal ones which are coupled by a leakproof bellows. One end of the bellows is welded to the external part of the replaceable socket piece, and the other end - to its internal part. The said internal part is rigidly connected to the guiding bush on which a resilient element is mounted between the collar of the guiding bush and the flange set on the external part of the replaceable socket piece and fixed to the collet sleeve.EFFECT: provision for leaktightness in case external bending forces occur on the side of the replaceable socket piece from a supply pipeline of a lower block in a launch vehicle.2 dwg |
