FLOW TAP

The invention relates to the device of a liquid tap.

It affects taps that are at the end of a pipe or pipeline are attached and the leakage of the liquid from the pipeline into a container or the blocking of this outlet after Enable demand.

Such taps are available in sanitary facilities! Bathtubs, Wash basins, etc. and are also used on containers in the fields of agriculture, animal husbandry, the chemical industry, etc. appropriate.

The tap device according to the invention is characterized in that it not only includes means that enable the leakage of liquid or the blocking of this outlet by manual operation, but also those through which the faucet, after it has been brought into the open position, resumes its closed position after an otherwise adjustable, predetermined amount of liquid has run out.

Such a device therefore makes it possible, in the case of a pipeline, to use a predetermined amount of liquid without any need to allow a monitoring to flow into a container.

It ensures that the amount of liquid permitted for the container is in no way greater than its capacity it completely eliminates overflow.

The following description, by way of example, refers to the accompanying drawing.

Figure 1 is a side view of a device according to the invention, Figure 2 is a corresponding plan view, Figure 3 is a sectional view taken along line 3-3 of Figure 2;

Figure 4 is a larger sectional view of part of the device Scale,

Figure 5 is a representation of part of the motion transmission, and Figure 6 is a side view of part of the actuating means.

The Hahnvorriohtung comprises a body 10 [Figures 1 to 3) in the general shape of a cylindrical housing or bowl with a Nozzle 1t for connection by means of thread 12 to a liquid inlet pipe or line, and with a diametrically opposite nozzle 13 provided for the liquid outlet, which is a

-2- 109853/1353

Have thread 14 for connection to an outlet pipe or after a Manifold outlet can be shaped. A partition 14 inside the Shell forms a chamber 15 of a quantity meter 15 *, the entrance of which is in communication with the input 11 of the device; the chamber 15 contains an impeller 17 and its output openings 18 are with a Container space 19 in connection. The quantity meter 15 * has an inner projection 20 for fastening the impeller 17 and an upper partition wall 21 through which the shaft 22 of the impeller 17 passes.

The shaft 22 carries a pinion 23 which leads to a reduction device 24 belongs, whose output shaft (FIG. 4) forms a unit with a sleeve 26, the end 27 of which bears a ring 28. This wreath has a lower disk, which is formed by an asymmetrical toothing 29 (Fig. 5) or switching toothing, which with an associated toothing. 30 cooperates, which on the upper disk of a sleeve 32 Associated rim 31 is formed, the outer surface of the sleeve by a thread 33 with the tubular body 34 of an actuating handwheel 35 (Figure 4) is connected. This actuating handwheel carries on its circular ring 37 markings 36, which move relative to a fixed mark 38 provided on the cover 39 of the housing 10.

The sleeve 32 is connected to a ring 42 (Figure 4), the lower Disk 43 (FIG. 6) has a front side extending perpendicular to the axis 44 with the exception of a recess 45, one of which is rounded 48 has inclined surface 46 adjoining a vertical part 47.

A roller 51 (FIG. 4) cooperates with the lower disk 43 which belongs to a valve device 52 (FIG. 3), the shoulder 53 of which

109853/1353

is under the action of a spring 54 and whose valve 55 is suitable, to cooperate with a seat 56 located between the discharge container space 19 of the flow meter and a space 57 is arranged in direct It is connected to the outlet of the device and is limited by a tubular stopper 58 which receives the spring 54.

The device works as followsχ

In the position shown in Figure 3, the cock is closed, the valve 55 prevents any connection between the inlet 11 and the outlet 13 of the device. To open the tap, it is sufficient to turn the actuating handwheel in the direction of arrow f (Figure 2) , as you normally open a tap. From this rotation, the roller 51, which was at the bottom of the recess 45 in the closed position, is pressed downwards under the action of the inclined edge 46, as a result of which the valve 55 is lifted from its seat and enables the connection between the inlet 11 and the outlet 13 of the device will. The liquid flows off and passes through the flow meter 15 ', the impeller of which is set in motion. By rotating the impeller 17 and interposing the reduction gear, the sleeve 42 is set in a rotary movement, the range of which is proportional to the flow of the liquid and takes place in the direction of arrow f (FIG. 6). If the opening actuation has brought the disk 43 into the position in which the end 55 of the disk 43 cooperates with the roller 51, the recess 45 Brst is advanced again to the roller 51 after one complete revolution; at the end of this single rotation, the valve closes, the roller 51 resuming its position on the bottom of the recess 45 and the valve 55 interrupting the connection again.

When the tap is operated, the rotation does not have point 55, but rather brought a point of the disk 43 further away from the recess 45 in front of the roller, then the recess 45 becomes a shorter one Revolution brought in front of the roller 51, so that the tap after The passage of a smaller amount of liquid closes.

In this way, the device can be adjusted so that the Leaking amount of liquid between the maximum volume, for example corresponds to the capacity of the container connected to the device, and a minimum amount which is very small can be and corresponds to an actuation of the tap, in which the area 56 of the disk 43 was brought in front of the roller 51.

The markings 36 can have numbers that indicate the liquid level which can run out if one or the other marking is brought in front of the fixed mark. You can also use a label be provided so that the container with which the device cooperates, one mark becomes full before the fixed mark, another half full, etc.
