DYC-JQ型－電磁真空帶充氣壓差閥  ■DYC-JQ型電磁真空帶充氣壓差閥是機(jī)械真空泵安全閥，安裝于機(jī)械真空泵的進(jìn)氣口，并與泵同步開(kāi)啟和關(guān)閉。當(dāng)泵停止工作或電源突然中斷時(shí)，閥門(mén)利用大氣壓力使閥板自動(dòng)關(guān)閉，使真空系統(tǒng)保持真空并將大氣充入泵腔內(nèi)，從而避免泵油逆向流動(dòng)而污染真空系統(tǒng)。適用介質(zhì)為純凈空氣和非腐蝕性氣體。 ■DYC-JQElectro-vacuum Differential Pressure Valve  ■DYC-JQ electro-vacuum differential Pressure valve is a safely valve for mechanical vacuum pump. It is mounted at the intake nozzle of mechanical vacuum pump, synchronously opened and closed with the pump. In case that pump stops working or power supply is suddenly broken off, valve disc will be closed automatically under atmospheric pressure, to keep the vacuum system vacuum and the air charged into pump cavity, thus to prevent pump oil from reverse flow that can pollute the vacuum system. Applicable medium can be pure air or noncorrosive gases. ■主要技術(shù)性能Main Technical Performance  ■■■ 適用范圍：Applicability 105～10-2Pa 閥門(mén)漏率：Valve Leak Rate ≤1.3×10-2Pa.L/S. 適用溫度：Applicable Temperature -30～+50℃ 線圍溫升：Coil Temperature Rise ≤65℃ 開(kāi)閉時(shí)間：Open-close Time ≤3S 電源電壓：Mains Voltage 220V/50Hz ■主要零件材料Materials of Main Parts  ■■閥體、閥蓋、閥板：碳鋼或鋁合金隔膜：丁橡膠加滌綸綢Body, bonnet and disc: carbon steel or aluminium alloyDiaphragm: NBR and terylene silk CONSTRUCTION FIGHTS (mm) ■外形及連接尺寸(mm)Overall and Connection Dimensions(mm)■活套法蘭連接(GB6070 圖一) Model型號(hào)DNDoDD2n-φcAHDYC-JQ505090110554-φ970203DYC-JQ6363105130684-φ988226DYC-JQ8080125145858-φ998260DYC-JQ1001001451651058-φ9108282DYC-JQ1601602002251658-φ12158350■快卸法蘭連接(GB4982 圖二) Model型號(hào)DND1DAHBDYC-JQ161617.2304016055DYC-JQ252526.2405017060DYC-JQ323234.2555817960DYC-JQ404041.2556518770DYC-JQ505052.2757020385■方體螺紋連接(JB919 圖三) Model型號(hào)DNDoD2hBHn-dDYC-JQ1616422228481484-M5DYC-JQ2525552935581554-M6DYC-JQ3232643640681604-M6DYC-JQ4040704444801664-M6DYC-JQ5050905556941894-M8DYC-JQ656510570651152054-M8DYC-JQ808012585751402504-M8DYC-JQ型－電磁真空帶充氣壓差閥_圣核閥門(mén)制造(上海)有限公司
