Abstract RU 2100679 C1

FIELD: valving. SUBSTANCE: each disk of the valving member from the side facing the seat is provided with a hollow. The diameter of the hollow is less than the inner diameter of the seat. Each disk is provided with a pressure-tight diaphragm which overlaps the hollow and deformed due to the pressure of fluid. The seat is conical. Being in contact with the seat, when the valve is closed, the diaphragm defines an additional sealing pair (sphere-cone). EFFECT: enhanced reliability. 3 dwg
