G941J-10襯膠電動(dòng)隔膜閥產(chǎn)品概述:
1、復合隔膜將閥體下部腔與閥蓋內腔隔開(kāi),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(zhì)*隔離,省去填料密封結構,介質(zhì)的內漏和外漏可同時(shí)避免。 2、做為執行元件的膜件由于頻繁的啟閉易產(chǎn)生疲勞斷裂,應視工況,介質(zhì)特性進(jìn)行定期更換。 3、塑料的防腐性能及推薦使用溫度見(jiàn)“及管路附件塑料襯里性能表。”閥門(mén) G941J-10 襯膠電動(dòng)隔膜閥設計規范 遵循GB/T 12239,BS 5156標準 襯膠隔膜閥驅動(dòng)方式 手動(dòng)襯膠隔膜閥、氣動(dòng)(常開(kāi)或常閉)襯膠隔膜閥、G941J-10 襯膠電動(dòng)隔膜閥 |
