Description

 The subject of the present invention is a device comprising a double tap intended to be placed between, on the one hand, a container of the lost packaging type containing, for example, sulfur dioxide intended for the treatment of wines and, on the other hand, a metering device which, when full, is partially or entirely emptied into a tank containing the wine to be treated.

 The device according to the invention has been studied with a view to being fixed horizontally on the dosing container to allow in a convenient way to fill and completely or partially empty this dosing container.

Indeed; the tanks containing the wine to be treated can be separated by a significant distance, it is absolutely necessary in the known prior devices to disconnect the metering container and the container
type with lost packaging or self-containing liquefied treatment gas, for example, sulfur dioxide.

Until now, the metering device has only had a single tap and, therefore, we were
brought to dismantle the liquefied gas supply pipes before connecting the pipe to the use container containing the wine to be treated.

 The present invention overcomes this disadvantage by creating a double tap device permanently mounted on the metering container, thus making it possible to maintain this device on the metering container at a fixed position to avoid any long and delicate handling.

According to the invention, the double tap device allowing the filling and the use of a liquefied compressed gas measuring device placed directly between the storage station and the use pipe is characterized in that it comprises a body central cylindrical containing, on either side of a central channel, a horizontal chamber occupied by globe valves controlled one by an operating button, the other by an operating button so as to
open or close junction heads, one connected to a storage tank, the other to a pipe directed onto at least one use tank, then the channel is drilled horizontally in its central zone by a channel passing through a sleeve for terminating by a pipe in a metering container, the venting of which at the time of filling is ensured by a pipe leading to a channel pierced in the sleeve, this channel opening out under a needle valve pierced in a chamber and controlling a channel evacuation allowing the evacuation of the gaseous phases to at least one bubbling tank for dissolution in general in water of this gaseous phase.

 According to another feature of the invention, the pipe is connected to a dip tube in the dosing container.

 Various other characteristics of the invention will also emerge from the detailed description which follows.

 An embodiment of the object of the invention is shown, by way of nonlimiting example, in the accompanying drawing.

 Fig. 1 is a diagram showing the installation of the double tap device on a metering device.

 Fig. 2 is a plan view, partly cut away, of the device comprising a double tap.

 Fig. 3 is a side elevation along arrow F3 in FIG. 2.

 Fig. 4 is a side elevation along arrow F4 in FIG. 2.

 Fig. 5 is an axial cross section of the device comprising a double tap.

 In fig. 1, there is shown a reservoir 1 which is sometimes of the lost packaging type containing a liquefied gas, for example sulfur dioxide. Therefore, when the tank 1 is in an inclined position on a support 2, it can be connected using a head connector 3 by flexible tubing 4 to a junction head 5 of the device according to the invention.

 As seen in fig. 2, the junction head 5 has an external thread 5a and is pierced with a channel 6 leading to a valve tap 7. The valve tap 7 is controlled by an operating button 8 placed at the right end of a cylindrical body central 9 comprising a horizontal chamber 10 containing the valve tap 7 whose longitudinal movement is limited by a stop screw 11 screwed into a hole 12 drilled in the central cylindrical body 9.

 The horizontal chamber 10 is extended at the center of the cylindrical body 9 by a channel 13 opening into the left part of the cylindrical body 9 in a horizontal chamber identical to the chamber 10 and also containing a valve tap similar to the valve tap 7 and which is controlled in its longitudinal displacement by an operating button 15.

 The operating button 15 allows using the corresponding valve tap to control the channel 16 drilled in the junction head 17 symmetrical to the junction head 5.

 Similarly to the junction head 5, the junction head 17 is externally threaded at 17a.

A stop screw 20 limits the horizontal movement of the valve tap operated by the operating button 15.

 In the central axis of the cylindrical body 9 is pierced a channel 21 which is extended by piercing a sleeve 24 (fig. 5) integral with the rear part of the cylindrical central body 9. In addition to the channel 21, the sleeve 24 has a channel 25 of small section which ends in the main body 9 in a chamber 27 containing a needle valve 28 (fig. 1) pierced with a central channel 29 extended by a channel 20 pierced in the center of a part 31 provided with 'an operating button 32. The part 31 ends with a fitting 34.

 Of course, the needle valve 28, placed in the chamber 27, is held on the upper part 9a of the central cylindrical body 9 by a safety sleeve 35 ensuring the sealing between these various parts using appropriate seals.

 The installation works as follows (see fig. 1).

 When the double-tap device is mounted via the sleeve 24, either directly or by means of a pipe 51, on a metering container 50, this metering container 50 is connected, via the channel 21, with the central channel 13 of the double tap device.

 The metering container 50 is connected, by channel 25, with chamber 27 and, by channel 29 when the needle valve is released from its seat, with channel 30 which is connected, by means of a pipe 53, to a tank containing water, for example for sparging for the gaseous phases contained in the metering container 50 when it is desired to fill this metering container 50 with liquefied gas.

The dosing container is filled as follows:
The operating button 15 makes it possible to close the corresponding valve tap and, as a result, the reservoir 1 can be connected by the pipe 4 to the junction head 5.

 The valve tap 7, controlled by the operating button 8, being open, the liquefied gas passes through the channel 6, the channel 13, the channel 21 and arrives via the line 51 in the metering container 50 through the discharge tube 50a .

 When the metering container 50 is full, which can be checked due to the external gauge 50b, the corresponding valve tap is closed using the operating button 8.

 The needle valve 1a of the tank 1 is then closed for safety.

 As soon as the metering container 50 has been filled, the needle valve 28 closes the channel 25, thus preventing any release of gas from the metering container 50.

 When it is desired to transfer a certain quantity of liquefied gas, from the dosing container 50> into the use tank 55 containing the product to be treated, it suffices to open the valve tap controlled by the operating button 15.

 The liquefied gas arrives from the container 30 through the line 51 and the channel 21 in the channel 13 then passes through the channel 16 of the junction head 17 in the line 56 connecting the junction head 17 to the use tank 55 .

 When the quantity of liquefied gas is sufficient, the operating button 15 makes it possible to close the corresponding valve tap, and the treatment is thus stopped.

 The quantity of liquefied gas injected into the use tank is calculated using the external gauge 50b of the dosing container 50.

 When the dosing container is empty, the procedure is repeated as above.

 It may be added that if the metering container 50 is not empty, it is possible, by opening the pipe 56 and connecting it to another use tank, pour into this latter tank a quantity of liquefied gas necessary for a treatment considered .

 These applications are particularly interesting as already said for the treatment of wines.

 In the example above, the valves controlled by the operating buttons 8 and 15 are sliding valves which can rest on seats provided in the cylindrical cQrps 9 at the ends of the channel 13. However, although such types of valves ensure a perfect seal, it is possible to replace them with other types of closures, for example pneumatic, electromagnetic or other valves, because it is possible using a simple programmer to make the filling of the metering container 50 automatic and the treatment in several use tanks 55 using a valve distributor placed in the pipe 56 and diverting the liquefied gas on several use tanks according to a determined cycle.

Of course, in this automatic case, the needle valve 28 is also subject to an automatic opening and closing command.
All the parts described above are obviously made of materials which are resistant to the agents under consideration.
