The core is of 5 fixed to the bottom wall of the tank threaded sleeve 8, having a drain hole 9, a limited waterproof saddle 10. The vessel 6 is limited, essentially, a cylindrical side wall 11, is open at the top and closed at its bottom by a bottom 12 having a Central hole 13, through which set the body 3 of the valve.

As shown in detail in figure 3, the wall 11 has a window 14, continuing down from the top edge 15 of the vessel 6. The window 14 is closed by a movable shutter 16, which slides parallel to the axis And, for the regulation of the opening window 14 and, consequently, the amount of water inside the vessel 6. More specifically, the shutter 16 is located on the outside wall 11 and has two opposite elastic wing 17, which protrude sideways from the gate 16, caplease with the corresponding lateral edges 18 of the box 14 and the attachment of the shutter 16 to the wall 11. The shutter 16 has two side tabs 19, which are concatenated with one of several 20 nests, made on the wall 11.

The frame 7 is essentially known and for the sake of simplicity, are not described in detail. Very briefly, the frame 7 includes two racks 21 adjustable height, inserted into corresponding slots 22 on the structure 2, and the upper cross member 23 supporting device 4 controls.

Case 3 valve comprises a tubular element 25 (which also acts as an overflow pipe)is placed inside the vessel 6 is slidable along the axis a and having a bottom barrier is 26, which interacts with waterproof saddle 10, closing the drain hole 9. The tubular element 25 is adjustable in length, and it is formed of two tubes 27, 28, telescopically connected in a known manner.

Figure 4 shows the valve body 3, which has a first latch 31, which is formed by the tooth 32, protruding radially outward from the outer lateral surface 33 of the housing 3 of the valve, and the second latch 34, which is formed by a pair of extension tabs 35 that protrude radially from the surface 33 in the opposite direction relative to the tooth 32, are aligned with each other and are located on opposite sides of the body 3 of the valve. The tooth 32 and the extension projections 35 are provided on the housing 3 of the valve at different heights along the axis A. More specifically, the tooth 32 is higher than the extension tabs 35, along the axis A.

Valve device 1 also includes an upper float 41 and lower the float 42, which are located inside the vessel 6 and interact with the body 3 of the valve. The floats 41, 42 are located at different heights along the axis a and, in particular, with the respective opposite axial ends of the vessel 6, and movable independently from each other, in relation to the body 3 of the valve together with changes in water level in the vessel 6, to selectively and independently coupled with the body 3 of the valve at different heights along about who and A.

The upper float 41 contains, essentially, a circular casing 45 of the float with a double wall surrounding the body 3 of the valve; the piston rod 46 continues vertically downward from the housing 45 of the float and the moving image is inserted into the guide 47 made inside the vessel 6 and the float 41 slides along the axis And in relation to the structure 2 and the connecting rod 48 to the lever 49, pivoted within the vessel 6.

One end 50 of the lever 49 pivotally attached to the vessel 6 and has a toothed latch 51, continuing radially in relation to axis A; and the free end 52 is attached to the rod 48.

As shown in detail in Figure 5, the casing 45 of the float has a radial through groove 54, the limited two opposite sides 55, which are connected by a crosspiece 56 to form the corresponding levers of the elastic gripping device 57 having two grip 58 and two lug 59 with the respective opposite edges. The rod 48 has a sequence of grooves 60, while the grippers 58 are intended for engagement with any of the grooves 60 to secure the rod 48 in a selected position to the float 41. The hooks 58 are detachable, in order to change the position of the hooks 58 on the rod 48 and, therefore, the distance between the float 41 and the lever 49; why the tabs 59 operated manually to move the grippers 58.

Lower the float 42 is located inside the vessel 6 near the lower wall 12, and pivotally attached to the structure 2 two rods 61, is inserted into the respective aligned holes 62, made in the wall 11. The float 42 is rotated around the axis of rotation formed by the rods 61, and essentially perpendicular to the axis A, and includes sector housing 63 float with two walls located radially outside and essentially coaxially in relation to the body 3 of the valve. The rods 61 are located in the lower end of the housing 63 of the float; the float 42 has a second latch 64, formed two teeth protruding from respective sides 65 of the housing 63 of the float for engagement with the extension tabs 35.

The floats 41, 42 are designed to selectively appropriate linked provisions, in which the floats 41, 42 together with the body 3 of the valve and prevent movement of the body 3 of the valve down a-axis, and the respective released positions, in which the floats 41, 42 is not coupled with the body 3 of the valve. Coupled position the top of the float 41 and the bottom of the float 42 is defined, respectively, first and second levels H1, H2 of the water in the vessel 6, and the second level N2 lower than the first level H1.

The device 4 controls (Figure 1), essentially known and therefore not described in detail for reasons of simplicity, and contains: Cup-shaped body 67 that is attached to a threaded rod 68 to the sleeve 69 n the cross member 23; the first and second buttons 71, 72 control, which, by means of the RAM 73, which is located a sliding manner inside the sleeve 69, act on the control lever 74 that is attached to the body 3 of the valve to lift the body 3 of the valve along the axis A.

Buttons 71, 72 slide parallel to the axis And at different lengths along it, occasionally lifting the valve body 3 to the respective different heights and releasing the appropriate amount of water. More specifically, the button 71 is moved to the first predetermined length L1, in order to lift the body 3 of the valve in the position of partial descent, in which case 3 valve coupled only. from the top of the float 41, but not with the lower float 42; and the button 72 is moved to the second predetermined length L2 greater than the first length L1 to lift the body 3 of the valve in the position of full descent, in which case 3 valve meshed with the lower float 42.

The operation of the valve device 1 is schematically shown in Fig.6. When the tank is full (Figa), the water in the tank and, therefore, the vessel 6 is on the source level N; case 3 the valve is in the closed position, in which the valve 26 closes the drain hole 9; floats 41, 42 swim supported by the water in the vessel, in the respective concatenated positions; latch 51, 64 are located above the respective latches 31, 34; and case 3, the valve is free to slide up along the axis A.

For partial descent the user clicks the button 71, which moves to the length L1, in order to lift the body 3 of the valve in the position of partial descent (Pigv), in which case 3 valve coupled only with the upper float 41 (when the latch 31 is located above the latch 51 and the bottom of the float 42 is not coupled with the body 3 of the valve (when the latch 34 is located under the tab 64). Water flows from the tank through the drain hole 9; and the movement of the body 3 of the valve downward under the force of gravity prevents adhesion of the float 41 with the body 3 of the valve, i.e. the engagement of the latch 51 with the latch 31.

When the water falls below the level of the H1 level, operate the float 41, the float 41, no longer supported by the water moves under the action of gravity in the released position, allowing, thus, the body 3 of the valve to slide down under the force of gravity to close the drain hole 9.

For a full descent, the user presses the button 72 (which moves to a length L2 that is greater than the length L1)to lift the body 3 of the valve in the position of full descent (Figs), in which each latch 31, 34 are located above the respective latches 51, 64. When the descent of water from the tank to the movement of the body 3 of the valve down prevents adhesion of the float 42 with the body 3 of the valve, i.e. the engagement of the latch 64 from the latch is m 34. Even when the water falls below the level of H1, so that the float 41 releases the body 3 of the valve body 3 of the valve still attached in the axial direction of the float 42, so that the drain hole 9 remains open. Only when the water falls below the level of H2 - level, operate the float 42, the float 42 receives the released position to the housing 3 with the valve closed drain hole 9.

Latch 51, 64 floats 41, 42, therefore, selectively and independently engage with the corresponding locking tabs 31, 34 when the changes in water level.

Valve device 1 also includes a system 75 for regulating the amount of lander water, which contains the window 14 and the gate 16. The number of lander water in partial descent regulate by simply moving the shutter 16 parallel to the axis a and the insertion of the projections 19 in the selected socket 20 to adjust the distance between the edge 15 of the vessel 6 and the shutter 16, and, hence, the opening window 14.

The position of the float 41 in relation to the structure 2 can also be adjusted using the gripping device 57. The pressing protrusions 59 to each other separates the hooks 58, so that the float 41 can be moved by a sliding movement along the axis And to insert the hooks into the selected groove 60. When the protrusions 59 are released, the float 41 remains fixed in the desired position in which Oseni lever 49.

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.
