Beschreibung
Zusammenfassung:	shut-off and adjusting fittings for pipe lines; mining and concentrating, chemical, oil and other industries; power engineering. SUBSTANCE: disk-type swivel gate has metal body; shut-off member mounted in body on swivel shaft; shut-off member is made in form of metal disk which is rubberized over entire surface; modulus of elasticity of rubber is Ed; seat arranged in body is made from rubber at modulus of elasticity Es. Modulus of elasticity of disk is larger than that of seat. Seat is mounted in body forming circular cavity between body and seat. This cavity is formed by groove found on inner surface of body; this groove has form of segment in cross section at length of chord "C" greater or equal to width "B" of body of gate, C
