GDQ型－气动高真空挡板阀  ■GDQ型气动高真空挡板阀是通过电磁换向阀改变气路方向，控制执行气缸驱动阀门作启闭运动。用于接通或切断真空管路中的气流。适用介质为纯净空气和非腐蚀性气体。带反馈信号装置。 ■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. ■主要技术性能Main Technical Performance  ■■■ 适用范围：Applicability 105～1.3×10-4Pa(轴封为橡胶) 105～1.3×10-5Pa(轴封为波纹管) 阀门漏率：Valve Leak Rate ≤1.3×10-4Pa.L/S.(轴封为橡胶) ≤1.3×10-5Pa.L/S.(轴封为波纹管) 适用温度：Applicable Temperature -25～+80℃(丁橡胶) -30～+150℃(氟橡胶) 气源压力：Annoy pressure 0.4～0.6MPa ■主要零件材料Materials of Main Parts  ■■阀体、阀盖、阀杆：铝合金、碳钢或不锈钢密封件：丁橡胶、氟橡胶、波纹管(轴封)。Body, bonnet and stem: aluminium alloy, carbon steel or stainless steelSealing element: NBR, Viton, bellows(shaft seal) CONSTRUCTION FIGHTS(mm) ■外形及连接尺寸(mm)Overall and Connection Dimensions(mm)■快卸法兰连接 Model型号DND1DAHBW法兰标准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 ■活套法兰连接 Model型号DNDDoD2APHn-φcDNy预抽口法兰标准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－气动高真空挡板阀_圣核阀门制造(上海)有限公司
