<p>Device with a double tap allowing the filling and use of an apparatus measuring liquefied compressed gas placed directly between the storage station and the user main, characterised in that it comprises a central cylindrical body 9 containing, on either side of a central channel 13, a horizontal chamber 10 occupied by tap valves 7, one controlled by a manoeuvring button 8 and the other by a manoeuvring button 15 so as to open or close junction heads 5 and 16, one connected to a storage tank 1, the other to a main going towards at least one user container 55, then the channel 13 is pierced horizontally in its central zone by a channel 21 passing through a sleeve 24 in order to end via a main 51 in a metering recipient 50 which is opened to the atmosphere at the filling moment via a main 25a ending in a channel 25 pierced in the sleeve 24, this channel 25 emerging under a needle valve tap 28 pierced in a chamber 27 and controlling an evacuation channel 29 - 30 allowing the evacuation of the gaseous phases to at least one bubble-through container for generally dissolving this gaseous phase in water. <IMAGE></p> |
