進(jìn)口氣動高真空擋板閥 ■VTON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(qū)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(zhì)為純凈空氣和非腐蝕性氣體。帶反饋信號裝置。 ■VTON 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) ■外形及連接尺寸(mm)Overall and Connection Dimensions(mm) ■快卸法蘭連接規(guī)格 Size DN D1 D A H B W 法蘭標(biāo)準(zhǔn) 10 10 12.2 30 30 120 52 40 GB4982 16 16 17.2 30 40 140 58 40 25 25 26.2 40 50 150 58 40 32 32 34.2 55 58 158 58 40 40 40 41.2 55 65 183 75 50 50 50 52.2 75 70 190 75 50 ■活套法蘭連接規(guī)格 Size DN D Do D2 A P H n-φc DNy預(yù)抽口 法蘭標(biāo)準(zhǔn) 50 50 110 90 55 70 95 278 4-φ9 GB6070 63 63 130 110 68 88 108 360 4-φ9 80 80 145 125 85 98 133 379 8-φ9 100 100 165 145 105 108 159 394 8-φ9 160 160 225 200 165 158 240 555 8-φ11 DN40 GB4982 200 200 285 260 208 200 280 623 12-φ11 DN50 GB6070 250 250 335 310 258 208 350 663 12-φ11 DN63 GB6070 320 320 425 395 328 250 425 832 12-φ14 DN80 GB6070 400 400 510 480 410 330 530 1120 16-φ14 DN100 GB6070 500 500 610 580 510 360 630 1036 16-φ14 DN125 GB6070 630 630 750 720 642 450 750 1415 20-φ14 DN160 GB6070 800 800 920 880 815 530 920 1850 24-φ14 DN200 GB6070 150 150 220 195 156 158 160 555 8-φ12 DN40 GB4982 JB919 300 300 380 350 308 250 250 832 8-φ14 DN80 GB6070 600 600 710 670 610 450 750 1415 12-φ21 DN150 GB919
