FIELD: valving.
SUBSTANCE: check valve comprises housing, valving member made of a spherical flexible plug reinforced by the rod. The housing is provided with the chamber. From one side, the chamber is bounded with a baffle having the passages for flowing fluid and central opening for setting and moving the spherical plug. From the opposite side, the chamber is bounded with the seat having the opening. The diameter of the opening is less than that of the plug by the value of deformation. The spherical plug is provided with a screw that is screwed into the reinforced rod and is used for control of its axial movement in the chamber of the housing.
EFFECT: enhanced reliability and prolonged service life.
