FIELD: machine engineering.
SUBSTANCE: invention relates to aeronautics. An airship combined gas valve has a casing with an opening for the gas flow passage, a valve plate with the hermetic landing zone, an opening and closing control mechanism of the valve plate. It is equipped with the hard rockings located on the circle perimeter around the central axis at the initial angle of not less than 3 degrees between the longitudinal axis of the rocking and the vertical. The hard rockings are fixed by one end in the hinge with two degrees of freedom on the valve plate surface, and the other end - in the hinge with three degrees of freedom on the base casing surface. The vertical displacement degree of freedom is limited with the elastic element and the adjustment screw of the valve opening start.
EFFECT: invention is intended to increase hermiticity.
