FIELD: construction.SUBSTANCE: group of inventions relates to valve industry and is intended for sealing pipes and valves. Corrugated pipes sealing assemblies consist of inner bellows (3), external bellows (4), top flange (5), first lower flange (2) and second lower flange (1). One end of inner bellows (3) is fixed on upper flange (5), and other end is secured at second lower flange (1). One end of external bellows (3) is fixed on upper flange (5), and other end is fixed on first lower flange (2). External bellows (4) is a sleeve enveloping internal bellows (3). Sealing assembly of corrugated pipes and valve with such assembly have advantages of rational structural properties and saving of material costs at reduced height of entire valve that has a favourable effect when valve is mounted in places with height limitations.EFFECT: disclosed is design of sealing assembly of corrugated pipes and valve with sealing assembly.4 cl, 4 dwg |
