水封閘閥

主要結(jié)構(gòu)特點(diǎn)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(dāng)接口通人壓力為061MP的水時(shí)，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(jiǎn)單、緊湊合理、檢修方便、使用壽命長(zhǎng)
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
閥們連接方式有法蘭和焊接兩種，驅(qū)動(dòng)方式為手動(dòng)和電動(dòng)
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(jī)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.
