摘要： A submerged nozzle change device has a slide valve unit 3 which is provided in a molten-metal outlet formed in a lower portion of a molten-metal containing vessel 1 for controlling the outflow of a molten metal. A pair of guide rails 26 for slidably suspending and supporting a holding case 6 mounted on an upper end of a submerged nozzle 5 are swingably supported on the slide valve unit 3 so that one end of each of the guide rails can be pivotally moved upwards and downwards about a shaft 21 while being biased upwards. On the free ends of the guide rails 24, there is provided a pushing cylinder 30 for pushing a new submerged nozzle 51 set on the guide rails 26 to push an old submerged nozzle 52 to the opposite side. A pair of guide rollers 35, which are moved by a piston rod 30a of the pushing cylinder 30, are brought into contact with the upper surfaces of the guide rails 26 to hold the guide rails 26 horizontally until a nozzle hole 52b of the old submerged nozzle 52 is out of register with a nozzle hole 11a of the slide valve unit 3 to close the nozzle hole 11a of the slide valve unit 3. An inclined cam 27 is provided for moving the guide rails 26 downwards until the new submerged nozzle 51 reaches the lower surface of the slide valve unit 3 after the nozzle hole 11a is closed. Thus, it is possible to provide a submerged nozzle change device which can quickly change a submerged nozzle and which can prevent the contact surface of a submerged nozzle from being scratched when a new submerged nozzle is caused to slide to move to a predetermined position.

摘要： A engageable joint having male pipe end and a female pipe end. The male and female pipe ends are removably engaged with gaskets. The gaskets are inflatable and arranged in a plurality of stages in the axial direction to inflatably seal a clearance between the pipe ends, and the joint has a clamp device for clamping the two pipe ends so that the pipe ends can be engaged and disengaged readily and reliably.
