Abstract

1. Coupling for the connection of gas supply lines to metallurgical vessels, in particular ladles for liquid steel, comprising one coupling half fixed to the vessel and a second, movable coupling half operated by an actuator, where, in the coupling's closed position, a gas-tight space is enclosed by the two coupling halves in which the gas lines end which are installed in the said coupling halves, the characteristic feature being that the gas supply source (6) is connected, on the one hand, via a spring-loaded shut-off valve (15) and a line (12) to the movable coupling half (4) mounted on the free end of an actuator rod (3) protruding from the actuator (1) and, on the other hand, via a second line (11b) and shut-off valve (13) to the pressure chamber (1a) of the actuator (1), so that the said gas supply source can be connected or disconnected, the actuator (1) being dimensioned so that the pressure determined by the spring load of the shut-off valve (15) will overcome both, the pressure prevailing in the coupling chamber (31) when the coupling halves (4, 5) are closed, and the load of a spring (10) counter-acting the operating stroke of the actuator piston (2).
