摘要:
A tank comprises a structural envelope made in a form of hemisphere with a tube connection having a ring groove in its surface. A tightening ring of the structural envelope. An elastic diaphragm made in a form of hemisphere integrated with a cylinder provided with an end projection that fits into the ring groove. A bottom is made in a form of a sphere part. A thin-walled ring with a shoulder is introduced that is mounted between the tightening ring and elastic diaphragm in the place of its end projection location. The tube flange is provided with an end projection. The tightening ring is equipped with a lateral flange providing a possibility for the thin-walled ring shoulder tightening by it to the ring projection of the tube flange. The external surface of the tightening ring and internal surface of the tube flange are made tapered in the direction from the ring groove to the hemisphere of the structural envelope above the ring groove. The bottom is made to be hollow and its' internal surface is provided with holes. A splitter is introduced that is mounted in the bottom space.
摘要:
A device comprises a bellows with protective rings arranged between corrugations of the bellows. Support rings are connected in a sealed manner to a gas line and a combustion chamber. A gimbal ring is positioned outside the bellows and via hinges is connected to structural brackets with support rings. A shield is mounted inside the bellows, the shield consisting of two cylindrical envelopes telescopically inserted one in another with a gap. The cylindrical envelopes are fixed in cantilever to support rings, forming a chamber which via channels for feeding a cooling working medium made in the support rings is connected to a main line for feeding the cooling working medium, and via the gap between the envelopes—to the cavity of the bellows unit. A housing is arranged outside the protective rings and adjoining them, and is made in the form of a metallic cylindrical helix, the ends of which are connected to the support rings (FIG. 2).
