K系列氣動加壓滑動水口節流機構為框架式左右開門機構，由上框架、滑動框架、下框架及內外水口座等主要部件組成，并且采用氣動板手加壓，使滑板界面壓力更加穩定，可達到較高的面壓值，使其不受高溫及人為因素影響，最大限度發揮滑板的使用壽命，降低了彈簧高溫失壓帶來的事故風險。

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.
