主要結(jié)構(gòu)特點及用途Chief strucure features and usages | ||||||
1、本產(chǎn)品的閥蓋填料室具有水密封結(jié)構(gòu),當(dāng)接口通人壓力為061MP的水時,可使系統(tǒng)與大氣隔離,保證系統(tǒng)具有良好的氣密性 | ||||||
2、S/Z型系列采用雙閘板雙向彈性密封、啟閉靈活、迅速、密封可靠。 | ||||||
3、產(chǎn)品結(jié)構(gòu)簡單、緊湊合理、檢修方便、使用壽命長 | ||||||
4、在管路上作啟閉裝置用,必須處于全開或全閉狀態(tài),不得用于調(diào)節(jié)流量 | ||||||
5、閥們連接方式有法蘭和焊接兩種,驅(qū)動方式為手動和電動 | ||||||
6、S系列水封閥門適用于公稱壓力100MPa,工作溫度425℃,工作介質(zhì)為水、蒸汽、油品和非腐蝕氣體的管路上作啟閉裝置用,尤其適用于火電廠汽機真空冷凝系統(tǒng) | ||||||
1.The chamber of packing of the valve's bonnet is of a water-sealed structure,which,when the water of 0.6-1MPa pressure goes into the mouthpiec,can make the system isolated from air to ensure the system with a good leak proofness | ||||||
2.Model S/Z series use dual-gate dual-direction elastic sealings.being flesible and fast to open and close,reliable sesling | ||||||
3.Simple,compact and reaso able structur,easy to overhaul and long duration | ||||||
4.When to be used as the open&close device on pipelines,it must be in fully-opened or fully-closed state and unallowed to be used for flow adjustment | ||||||
5.Two ways of connection:by flange and welding,two driving ways:manually and electrically | ||||||
6.Suitable to act as the open & close device for the pipelines with the working medium of water,steam,oil goods and non-corrosive gas,especially for the vacuum condensation system of the steam tufbine in steam power palnts. |
