Filling float-valve // 2351835

FIELD: machine building.

SUBSTANCE: present invention pertains to hydro-automation, particularly to hydraulic inlet valves with dosed supply of liquid into a filling tank, and is meant for use in systems for filling different types of reservoir with water. The filling float-valve has housing with an inlet, an outlet opening and a seat inside the housing in form of a nozzle, a gate opposite the seat, in form of an elastic membrane with thickening in the area where it is in contact with the seat. The axially moveable coupling of the gate is on an arm support. The arm support is fixed against the housing using a cap nut and is kinematically linked to the float through a lever and a tie-rod. The float is fitted with provision for vertical displacement. The perimeter of the membrane is pressed into the housing by the arm support with a cap nut, forming a cavity in the housing on the side of the seat. The cavity is linked to the outlet opening and, through the nozzle, to the inlet. There is a cavity on the arm support above the membrane. This cavity is linked to the cavity in the housing through at least one opening on the membrane. The coupling rod is pressed against the arm support using stocking type sealing rings. Inside the cavity in the housing, on the side of the seat, an encircling seat is fitted, forming an annular gap, as well as a throttle insertion which is in form of a cup. A bypass hole is made at the bottom of the latter. The perimeter of the membrane is pressed between the bottom of the cup and the arm support. An outlet opening is made in the side wall of the cup. On the inner wall of the cup and the outer side surface of the seat there are radial ribs with formation by the latter in the annular gap, a labyrinth in the cross-section of the throttling channel.

EFFECT: increased reliability and easier operation of a filling float-valve.
