SU549789A2 - A device for adjusting the level of liquid in tanks - Google Patents

Description

and longitudinal movement, the disk 5 is rigidly fixed, which, together with the disk 6 fixed in the housing /, form the disk locking member c. the initial gap gap A.

Holes B are made in the disks, which are arranged in such a way that at the lowest position of the float 7 they coincide and form through openings in pairs. On the axis of the cantilever lever 8 fixed with a float 7.

The fixture is installed inside the container 9.

On the back side of the housing 1, there is formed a membrane 10 and a lid 11, chamber C, and the membrane area is larger than the disk 5. The fitting 12 is connected to pipeline 13 with a shut-off valve 14 connecting chamber C to the discharge line 15, through which fluid is supplied to tank 9 through leveling device.

In the membrane 10, a sleeve 16 is installed with a through hole of small diameter (drainage hole) D, fixed by a disk support 17 with a nut 18.

The end part .E of axis 3 is in contact with the sleeve 16, in which the nest P. is made. A spring 19 is installed in the socket, with its ends simultaneously abutting against the bottom of the socket F, and into the sleeve 1-6.

The adaptation works as follows.

When filling the tank 9 through the pressure line 15 with a liquid of its notes, the disk 5 is pressed against the disk 6, thereby reducing the gap gap L to zero. Then, through the holes B in the disks, the liquid flows through the body / directly into the container 9.

The fluid level gradually rises. The float 7 pops up and through the lever

8, the axis 3 rotates, which rotates the disk 5 relative to the disk 6. In this case, the holes B of the disk 5 overlap with the plane of the disk 6 and vice versa. As a result, the initial section of the device and, consequently, the flow rate of the fluid entering the container 9, is gradually reduced.

When the liquid reaches the upper level, the float 7 occupies the upper limit position, the holes B in the disks 5 and b completely overlap, and the filling of the container stops.

For mixing the liquid, the pump is turned on, pumping the liquid from the tank 9 through the suction pipe (not shown) and again feeding this liquid through the pressure line 15 to the tank

9 through the device. But as before

when the container was filled, the holes B in the disks 5 and 6 were blocked, and the gap gap A was reduced to zero by the displacement of the disk 5, the liquid did not enter the container 9. At that, valve 14 opens, and pressure in pressure line 15 spreads from it through conduit 13 through fitting 12 to chamber C. This pressure acts on membrane 10. Because the membrane area is larger than disk 5, it deflects and pushes Ifi. axis 3, which is displaced along the body. As a result, the disk 5 moves away from the disk 6, and a gap gap L is formed between them again. The liquid enters the container 9 through this gap. Thus, the mixing process takes place.

At the end of the mixing, it is necessary that the gap gap L becomes zero again; otherwise, if the pump is incorrectly turned on to fill the container 9, the device will not interfere with filling, and overflow can occur.

The emergency situation is eliminated when the valve 14 is closed. Then the overpressure in chamber L is vented through the drainage hole D into the container due to the fact that the spring 19 (although with little effort) nods the sleeve 16 with the membrane 10 from the end part E of axis 3, and the excess the pressure in the pressure line 15 presses (taking into account the absence of resistance to the membrane 10) disk 5 to disk 6, and there is no gap.

The implementation of the proposed solution will make it possible to extend the field of application of such devices and, most importantly, to qualitatively average, for example, aviation fuel before refueling it in aircraft with fuel tankers, in one of whose models the device is currently being inserted.
