FIELD: medicine.SUBSTANCE: group of inventions refers to medical equipment. A valve comprises a valve seat having a female cone with a hole having a bevel-cut surface, and a valve membrane comprising a tapered portion having a base and a point. The tapered portion is configured fit at a stretch inside the female cone of the valve seat. The valve membrane is configured to pass the fluid from an inlet along a flow path between the female cone and tapered portion to an outlet when the valve membrane is undeformed, and block the flow path from the inlet to outlet when the valve membrane is radially deformed. The valve seat and the valve membrane are configured so that the tapered portion is gapped from the bevel-cut surface when the valve membrane is undeformed, whereas the gap gets closed when the valve membrane is radially deformed. A slot between the tapered portion point and bottom is closed that leads to radial deformation of the tapered portion. Disclosed are the system and valve within the fluid supply system.EFFECT: inventions aims at providing uncomplicated control.16 cl, 10 dwg |
