BELLOWS COMPENSATING FACILITY Russian patent published in 2010 - IPC F16L51/03 F16J3/04 

FIELD: machine building.

SUBSTANCE: invention is designed for compensating deformations and vibrations of pipeline systems of high pressure in all branches of industry. The facility consists of two similar unloaded bellows compensators 1 and 2 rigidly coupled with branch 3. Compensators 1 and 2 consist of similar end bellows 4 and 6 of smaller diametre rigidly tied with middle bellows 5 of bigger diametre by means of two intermediate flanges 7 and 8; and are rigidly connected to end flanges 9 and 10. Each end flange is rigidly coupled with the second from it intermediate flange by means of unload rods 11 arranged outside end bellows 4, 6 and inside middle bellows 5. Rods 11 are run through openings 14 of intermediate flanges 7, 8 and inside middle bellows 5 they are insulated from working medium with flexible elements 15. Through openings 14 facilitate relative travels of rods 11 in these openings at maximal angular displacements of compensators 1, 2.

EFFECT: raised stability and technical characteristics of facility.
