活塞式(shì)流量調節(jiē)閥産品概述

      活塞(sāi)式流量(liàng)調節閥是本公司技術人員在借鑒(jiàn)德國、日(rì)本先進經(jīng)驗,總結國内設計制造及實用經驗(yàn)的(de)基礎上,根據流體力學特性而開發出來的調(diào)速調壓型(xíng)閥門。已經(jīng)在電站、引水、供水等領域得到(dào)了廣泛的應用。經過改進(jìn)的本系列流(liú)量調節閥不(bú)但适用于(yú)清水,對(duì)于天然江河湖泊水、輕度污(wū)水具有良好的耐受能力(lì)。從設計結構和材料(liào)選用上解決了多年來流(liú)量調節閥易結垢,卡阻,驅動裝置(zhì)偏大(dà)的難題。
