进口气动高真空挡板阀

进口气动高真空挡板阀 ■VTON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。 ■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℃(丁腈橡胶) 　-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：丁腈橡胶、氟橡胶、波纹管(轴封)。 Body, bonnet and stem: aluminium alloy, carbon steel or stainless steel Sealing element: NBR, Viton, bellows(shaft seal) ■外形及连接尺寸(mm)Overall and Connection Dimensions(mm) ■快卸法兰连接规格 Size DN D1 D A H B W 法兰标准 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 ■活套法兰连接规格 Size DN D Do D2 A P H n-φc DNy预抽口 法兰标准 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
