K系列气动加压滑动水口节流机构为框架式左右开门机构，由上框架、滑动框架、下框架及内外水口座等主要部件组成，并且采用气动板手加压，使滑板界面压力更加稳定，可达到较高的面压值，使其不受高温及人为因素影响，最大限度发挥滑板的使用寿命，降低了弹簧高温失压带来的事故风险。

Type K Pneumatic Pressure-loading Slide Gate System is a frame structured right-and-left opening mechanism consisting of upper framework, sliding framework, lower framework, inner and outer nozzle seat, etc. With a pneumatic pressure-loading device, optimal face pressure distribution between slide plates can be guaranteed and higher pressure value can be reached, shielding slide plates from being affected by high temperature and human factors, maximizing their service life, and reducing accident risk brought by pressure loss of springs at high temperature.
