德国莱克LIK品牌:进口高压蒸汽调节阀-平衡式迷宫调节阀,采用迷宫式阀笼结合平衡式阀芯设计。迷宫式套筒由同多个同轴表面分布着迷宫曲径的圆柱碟片组成。根据介质工艺参数不同,设计不同的迷宫曲径规格与叠合层数组成阀笼,阀笼将总的流道分成许多细小的迂回甚至台阶状分布的节流流道,迫使流体不断地改变流向与流通面积逐步降低流体的压力,以达到预防闪蒸空化的发生,延长阀内件的使用寿命。采用平衡式套筒阀芯,阀芯与阀座的紧密配合确保了极低的泄漏。此种阀内件适合于各种易产生阻塞流动造成汽蚀的工况。

高压迷宫式调节阀

Series balanced labyrinth control valve adopts the labyrinth cage and balanced plug design. The labyrinth cage is composed of cylindrical discs with many coaxially distributed labyrinths. According to different technological parameters of the media, different labyrinth specifications and piling layers are designed to form the cage and the cage divides the whole flow channel into several tiny circuitous or step flow channels, forcing the fluids to continuously change the flow direction and flowing area and gradually reducing the pressure of fluids, so as to prevent the occurrence of flash evaporation and cavitation and prolong the service life of the trim. The balanced cage plug is adopted. The closely fit plug and seat ensure very low leakage. The trim is suitable for service conditions under which blocked flow will easily be produced and cavitation will be caused.
