Abstract:
A tank for the liquid storage and expulsion comprising:(a) a structural envelope made in a form of hemisphere and integrated by its end with the end of tube flange located along the longitudinal axis of hemisphere and having a ring groove in its internal surface;(b) a connection for filling and discharging the liquid that is mounted in said structural envelope, and a tightening ring located coaxially with the longitudinal axis of said structural envelope;(c) an elastic diaphragm fastened between said tube flange and said tightening ring and made in a form of hemisphere integrated by its end with a cylinder with an end projection made on the external surface of its base that fits into the ring groove of said tube flange, the external surface of said tightening ring and internal surface of said tube flange having a form of a cylinder in the place of location of the end projection in the ring groove;(d) a bottom made in a form of a sphere part providing a possibility for its end influence upon the end of said tightening ring and a possibility for its leak-proof connection to the tube flange of said structural envelope, and made to be hollow, while its internal surface is provided with holes;(e) a connection for the control gas feed mounted in said bottom;(f) a splitter mounted in the space of said bottom in the place of location of said connection for the control gas feed;(g) a thin-walled ring that is provided with a shoulder on the end and is mounted between said tightening ring and said elastic diaphragm in the place of location of its end projection;(h) a tube flange that is provided with a ring projection located on the internal surface of the tube flange from the side of said bottom ahead of said ring groove, and said tightening ring is provided with a lateral flange from the side of a bottom to tighten the shoulder of said thin-walled ring by it to said ring projection of the tube flange, the external surface of said tightening ring and internal surface of the tube flange in the direction from the ring groove to the hemisphere of structural envelope over the ring groove are made tapered making an acute angle with the longitudinal axis of said structural envelope.
