PRESSURE RECEIVER Russian patent published in 2021 - IPC F17C1/16 F17C13/00 

FIELD: gas storage.

SUBSTANCE: invention relates to gas storage. The pressure receiver (1) contains a polymer sealed liner (2) and a reinforcing layer (4) of composite material formed outside around the sealed liner (2), a sleeve (5) connected to the sealed liner (2) and with a reinforcing layer ( 4) to form the hole (6) of the pressure receiver (1). The sealed insert (2) is integrated with the sleeve (5) by means of an annular joint zone (7) of co-formed metal and polymer, in which, in the annular joint zone (7), the metal sleeve (5) is internally lined with a polymer intermediate layer (8), co-molded with the metal surface (13) of the sleeve (5). The sealed liner (2) is molded together with the polymer intermediate layer (8), in which the material of the polymer intermediate layer (8) has an adhesive ability to the metal of the sleeve (5) is greater than the adhesion of the polymer material of the sealed liner (2) to the metal of the sleeve (5). The valve (9) is screwed into the sleeve (5), removed from the sealed liner (2) and from the intermediate layer (8) and does not come into contact with either the sealed liner (2) or the intermediate layer (8).

EFFECT: invention is aimed at ensuring gas tightness during long periods of operation.
