进口高压迷宫式调节阀
产品概述
进口高压迷宫式调节阀是一种高性能的阀门产品，专为高压、高温及易产生汽蚀、噪音和震动的工况环境设计。该阀门采用迷宫式阀笼结合平衡式阀芯设计，通过强制介质流经多级拐弯流道，达到逐级降压、控制流速的目的，从而有效预防闪蒸空化现象，延长阀内件的使用寿命。该产品广泛应用于电站、冶金、石化等行业，以其卓越的抗汽蚀性能和精确的流量控制功能而著称。
产品详情
进口高压迷宫式调节阀，采用了迷宫式阀笼，迷宫式阀笼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。

The imported high-pressure labyrinth control valve adopts a labyrinth cage. The labyrinth cage is composed of cylindrical discs with labyrinth paths distributed on multiple coaxial surfaces. According to different medium process parameters, different labyrinth path specifications and the number of superimposed layers are designed to form the valve cage. The valve cage divides the total flow channel into many small tortuous or even stepped throttling flow channels, forcing the fluid to constantly change the flow direction and the flow area to gradually reduce the fluid pressure to prevent the occurrence of flash evaporation and cavitation and extend the service life of the valve internals.
Specification parameters
