Title:
SLIDING GATE
Document Type and Number:
Japanese Patent JP2017221960
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a sliding gate capable of certainly avoiding the releasing of a surface pressure load during open/close control of a nozzle outflow port, while realizing the opening/closing of the nozzle outflow port and the releasing of the surface pressure load in a surface pressure loading state between a fixed plate and a slide plate, due to slide movement by the same slide device, with a simple structure.SOLUTION: A sliding gate includes: a fixed plate; a slide plate; a slide device which makes a slider case holding the slide plate slide in an opening/closing direction of the nozzle outflow port; a surface pressure load mechanism which loads surface pressure between the fixed plate and the slide plate when regulating slide movement exceeding a normal slide range of the slider case by the slide device, and on the other hand, releases the surface pressure load when permitting the slide movement exceeding the normal slide range; and a stopper mechanism which moves a position so as to selectively switch the permission/prohibition of the slide movement exceeding the normal slide range.SELECTED DRAWING: Figure 2
