進(jìn)口高壓迷宮式調(diào)節(jié)閥
產(chǎn)品概述
進(jìn)口高壓迷宮式調(diào)節(jié)閥是一種高性能的閥門產(chǎn)品,專為高壓、高溫及易產(chǎn)生汽蝕、噪音和震動(dòng)的工況環(huán)境設(shè)計(jì)。該閥門采用迷宮式閥籠結(jié)合平衡式閥芯設(shè)計(jì),通過強(qiáng)制介質(zhì)流經(jīng)多級拐彎流道,達(dá)到逐級降壓、控制流速的目的,從而有效預(yù)防閃蒸空化現(xiàn)象,延長閥內(nèi)件的使用壽命。該產(chǎn)品廣泛應(yīng)用于電站、冶金、石化等行業(yè),以其卓越的抗汽蝕性能和精確的流量控制功能而著稱。
產(chǎn)品詳情
進(jìn)口高壓迷宮式調(diào)節(jié)閥,采用了迷宮式閥籠,迷宮式閥籠由同多個(gè)同軸表面分布著迷宮曲徑的圓柱碟片組成。根據(jù)介質(zhì)工藝參數(shù)不同,設(shè)計(jì)不同的迷宮曲徑規(guī)格與疊合層數(shù)組成閥籠,閥籠將總的流道分成許多細(xì)小的迂回甚至臺階狀分布的節(jié)流流道,迫使流體不斷地改變流向與流通面積逐步降低流體的壓力,以達(dá)到預(yù)防閃蒸空化的發(fā)生,延長閥內(nèi)件的使用壽命。

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.
