Gas-dispensing device and facility comprising such a device

摘要

The invention relates to a gas-dispensing device for connecting a plurality of pressurized gas sources (E1, E2, E3, E4) to a user, the device including a housing provided with a plurality of gas inlets to be connected to respective gas sources (E1, E2, E3, E4) and an outlet to be connected to a user member, a dispensing member that selectively movable, relative to the body, into separate dispensing positions for selectively putting each inlet in communication with the outlet in turn, while the other inlets are isolated from the outlet, characterized in that the device comprises an emergency discharge system that is movable into an operative position in which all the gas inlets are simultaneously forcedly connected to a gas discharge outlet.

主权项

1. A gas-dispensing device for connecting a plurality of pressurized gas sources sequentially to a user, the device comprising:
a housing provided with a plurality of gas inlets intended to be connected to respective gas sources; an outlet intended to be connected to a user member, wherein a dispensing member is selectively movable relative to the body into distinct dispensing positions permitting each inlet to be brought into communication selectively and in turn with the outlet while the other inlets are isolated from the outlet; and an emergency discharge system capable of displacement into an active position in which all the gas inlets are brought simultaneously into a forced relationship with a gas discharge outlet, wherein the emergency discharge system is capable of displacement from a neutral position towards the active position, wherein:
in the neutral position, the emergency discharge system allows the selective displacement of the dispensing member into the dispensing positions in the sense that, in the active position, the emergency discharge system displaces the dispensing member into a disengaged position preventing the dispensing positions;the dispensing member is forced by a resetting member towards the disengaged position;in the neutral position, the emergency discharge system forms a removable stop preventing the displacement of the dispensing member towards the disengaged position; andthe emergency discharge system includes a thermal fuse.
