FIELD: mechanical engineering. SUBSTANCE: closing disc can roll freely over valve axle in valve body. Center of gravity of closing disc is offset from its axis of symmetry to ensure returning of said disc in closed position (tilling doll effect). EFFECT: improved matching of contact surfaces in valve body and closing disc achieved by making bracket as toothed segment interacting with pin-tooth rack secured in body. 3 cl, 2 dwg
