所屬類別：真空閥 GDQ ■ GDQ型－氣動高真空擋板閥 ■ GDQ型氣動高真空擋板閥是通過電磁換向閥改變氣路方向，控制執(zhí)行氣缸驅動閥門作啟閉運動。用于接通或切斷真空管路中的氣流。適用介質為凈空氣和非腐蝕性氣體。 帶反饋信號裝置。 ■ GDQ Pneumatic 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℃(丁腈橡膠) 　-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：丁腈橡膠、氟橡膠、波紋管(軸封)。 Body, bonnet and stem: aluminium alloy, carbon steel or stainless steel Sealing 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 DN D1 D A H B W 法蘭標準 GDQ-J10(b) 10 12.2 30 30 120 52 40 GB4982 GDQ-J16(b) 16 17.2 30 40 140 58 40 GDQ-J25(b) 25 26.2 40 50 150 58 40 GDQ-J32(b) 32 34.2 55 58 158 58 40 GDQ-J40(b) 40 41.2 55 65 183 75 50 GDQ-J50(b) 50 52.2 75 70 190 75 50 ■ 活套法蘭連接 Model 型號 DN D Do D2 A P H n-φc DNy預抽口 法蘭標準 GDQ-J50 50 110 90 55 70 95 278 4-φ9 GB6070 GDQ-J63 63 130 110 68 88 108 360 4-φ9 GDQ-J80 80 145 125 85 98 133 379 8-φ9 GDQ-J100 100 165 145 105 108 159 394 8-φ9 GDQ-J(S)160 160 225 200 165 158 240 555 8-φ11 DN40 GB4982 GDQ-J(S)200 200 285 260 208 200 280 623 12-φ11 DN50 GB6070 GDQ-J(S)250 250 335 310 258 208 350 663 12-φ11 DN63 GB6070 GDQ-J(S)320 320 425 395 328 250 425 832 12-φ14 DN80 GB6070 GDQ-J(S)400 400 510 480 410 330 530 1120 16-φ
