GDQ型－氣動(dòng)高真空擋板閥  ■GDQ型氣動(dòng)高真空擋板閥是通過(guò)電磁換向閥改變氣路方向，控制執(zhí)行氣缸驅(qū)動(dòng)閥門(mén)作啟閉運(yùn)動(dòng)。用于接通或切斷真空管路中的氣流。適用介質(zhì)為純凈空氣和非腐蝕性氣體。帶反饋信號(hào)裝置。 ■GDQPneumatic High Vacuum Flapper Valve  ■GDQ pneumatic high vacuum flapper valve uses solenoid directional valve to change the direction of air passage, and controls the actuating cylinder to drive the valve opened and closed. It is used to put through or cut off the airflow in vacuum pipeline. Applicable medium can be pure air and noncorrosive gases.With signal feedback device. ■主要技術(shù)性能Main Technical Performance  ■■■ 適用范圍：Applicability 105～1.3×10-4Pa(軸封為橡膠) 105～1.3×10-5Pa(軸封為波紋管) 閥門(mén)漏率：Valve Leak Rate ≤1.3×10-4Pa.L/S.(軸封為橡膠) ≤1.3×10-5Pa.L/S.(軸封為波紋管) 適用溫度：Applicable Temperature -25～+80℃(丁橡膠) -30～+150℃(氟橡膠) 氣源壓力：Annoy pressure 0.4～0.6MPa ■主要零件材料Materials of Main Parts  ■■閥體、閥蓋、閥桿：鋁合金、碳鋼或不銹鋼密封件：丁橡膠、氟橡膠、波紋管(軸封)。Body, bonnet and stem: aluminium alloy, carbon steel or stainless steelSealing element: NBR, Viton, bellows(shaft seal) CONSTRUCTION FIGHTS(mm) ■外形及連接尺寸(mm)Overall and Connection Dimensions(mm)■快卸法蘭連接 Model型號(hào)DND1DAHBW法蘭標(biāo)準(zhǔn)GDQ-J10(b)1012.230301205240GB4982GDQ-J16(b)1617.230401405840GDQ-J25(b)2526.240501505840GDQ-J32(b)3234.255581585840GDQ-J40(b)4041.255651837550GDQ-J50(b)5052.275701907550 ■活套法蘭連接 Model型號(hào)DNDDoD2APHn-φcDNy預(yù)抽口法蘭標(biāo)準(zhǔn)GDQ-J5050110905570952784-φ9 GB6070GDQ-J636313011068881083604-φ9 GDQ-J808014512585981333798-φ9 GDQ-J1001001651451051081593948-φ9 GDQ-J(S)1601602252001651582405558-φ11DN40 GB4982GDQ-J(S)20020028526020820028062312-φ11DN50 GB6070GDQ-J(S)25025033531025820835066312-φ11DN63 GB6070GDQ-J(S)32032042539532825042583212-φ14DN80 GB6070GDQ-J(S)400400510480410330530112016-φ14DN100 GB6070GDQ-J(S)500500610580510360630103616-φ14DN125 GB6070GDQ-J(S)630630750720642450750141520-φ14DN160 GB6070GDQ-J(S)800800920880815530920185024-φ14DN200 GB6070GDQ-J(S)1501502201951561581605558-φ12DN40 GB4982JB919GDQ-J(S)3003003803503082502508328-φ14DN80 GB6070GDQ-J(S)600600710670610450750141512-φ21DN150 GB919GDQ型－氣動(dòng)高真空擋板閥_圣核閥門(mén)制造(上海)有限公司
