FIELD: covers or closure members for pressure vessels.
SUBSTANCE: valve comprises cover provided with cantilevers and mounted on the thread inside the housing, sealing member, and two movably interconnected ties. One of the ties is pivotally connected with a ring grip mounted on the cantilever made on the housing for permitting rotation around its axis. The valve also has a valving member which is composed of lug pivotally connected with the second tie and two planks. One end of the planks is provided with pins which are fixed in the bushing of the cantilevers. The cantilevers are secured to the diametrically opposite sides of the threaded section of the cover. The other ends of the planks are secured to the lug. The angle between the axis of two ties and straight line, which passes through the axis of the pivoting joint of the lug with the second tie and longitudinal axis of the housing, should be no less than 
.
EFFECT: improved pressure-tightness of the valve.
