Filling valve operates as follows.

In the initial position, when filled with liquid, such as water, the tank is empty, the float 9 is in its lower position in the Cup 16, the lever 7 does not press the valve 15 to the nozzle 11 and the cavity of the cover 6 through the nozzle 11 is communicated with the outside of the valve space. When this elastic locking element 5 is not pressed against the seat 4 of the housing 1. The saddle 4 is open for admission of fluid to fill it to capacity (not shown). On the inlet pipe 2 liquid through the saddle 4 enters the annular cavity 10 and then through echodnou pipe 3 enters the filled fluid container. As the filling capacity increases the level of the liquid and when the liquid reaches the float valve 18, the latter rises and closes the opening 17 in the bottom of the Cup 16. When the liquid reaches the upper edge of the Cup 16 fluid begins to fill the Cup 16. As a result, the float 9 is beginning to emerge that calls through rod 8 of the lever 7. Last, turning relative to the cover 6 covers the nozzle 11 by the valve 15. As a result, the liquid from the inlet pipe 2 through the annular cavity 10 and a calibrated orifice 13 in the elastic locking element 5 is supplied into the cavity of the cover 6, the pressure on the membrane sleeve 20 and through it on the elastic locking element 5 from the back side, causing it to move and elastic locking element 5 in the direction of the saddle 4. Elastic locking element 5 gradually, as the buoyancy of the float 9 is moved toward the seat 4 and eventually blocks the exit seat 4 liquid filled in the container.

When emptying the liquid from the Cup 16 is drained through the hole 17 of the float valve 18, the float 9 is lowered, which causes reverse rotation of the lever 7 to its original position. As a result of rotation of the lever 7, the valve 15 moves away from the nozzle 11, opening it. As a result, the pressure in the cavity of the cover 6 drops the pressure of the fluid in the input Petrovka and under its own force of elasticity of the elastic locking element 5 otlavlivatsya from seat 4, freeing the passage for the liquid. The filling capacity of the liquid is repeated, as described above.

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.
