主要結(jié)構(gòu)特點及用途: Chief strucure features and usages:
- 本產(chǎn)品的閥蓋填料室具有水密封結(jié)構(gòu),當接口通人壓力為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
- 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。
- 產(chǎn)品結(jié)構(gòu)簡單、緊湊合理、檢修方便、使用壽命長
- 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
- *連接方式有法蘭和焊接兩種,驅(qū)動方式為手動和電動
- 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)
- 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
- Model S/Z series use dual-gate dual-direction elastic sealings.being flesible and fast to open and close,reliable sesling
- Simple,compact and reaso able structur,easy to overhaul and long duration
- 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
- Two ways of connection:by flange and welding,two driving ways:manually and electrically
- 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.
