詳細內容：一、軸流式電動調節(jié)閥產品概述
隔膜閥是一種特殊形式的具有截斷功能的閥門，其啟閉件由鋼質閥瓣與軟質材料（橡膠和氟塑料復合）制成的隔膜組成，并將閥體內腔隔開以達到截斷管內介質之目的。
二、軸流式電動調節(jié)閥基本結構
1、復合隔膜將閥體下部腔與閥蓋內腔隔開，并與之形成直流通道，使隔膜上部的閥桿，閥瓣等內件與介質完全隔離，省去填料密封結構，介質的內漏和外漏可同時避免。
2、做為執(zhí)行元件的膜件由于頻繁的啟閉易產生疲勞斷裂，應視工況，介質特性進行定期更換。
3、塑料的防腐性能及推薦使用溫度見“閥門及管路附件塑料襯里性能表�！�
軸流式電動調節(jié)閥設計規(guī)范
