产品简介: |
GD | | ■ | GD型-高真空挡板阀 | | | ■ | GD型高真空挡板阀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。高真空挡板阀按轴封结构可分GD-J型橡胶轴封和GD-J(b)型波纹管轴封两种。按通导形式可分GD-J为角通型式,GD-S为带预抽口的三通型式。 | | | ■ | GD High Vacuum Flapper Valve | | | ■ | GD high vacuum flapper valve is used to put through or cut off the airflow in vacuum pipeline. Applicable medium can be pure air and noncorrosive gases. According to its shaft seal structure, high vacuum flapper valve is classified into GD-J rubber shaft seal type and GD-J(b)bellows shaft seal type. According to its put-through type, it is classified into GD-J angle type and GD-S three-way type with prepumping. | | | ■ | 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) | | | | ■ | 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) | | | 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 | DN | D1 | D | A | H | P | 法兰标准 | GD-J10(b) | 10 | 12.2 | 30 | 40 | 124.5 | 60 | GB4982 | GD-J16(b) | 16 | 17.2 | 30 | 40 | 124.5 | 60 | GD-J25(b) | 25 | 26.2 | 40 | 50 | 134.5 | 78 | GD-J32(b) | 32 | 34.2 | 55 | 58 | 153 | 78 | GD-J40(b) | 40 | 41.2 | 55 | 65 | 160.5 | 78 | GD-J50(b) | 50 | 52.2 | 75 | 70 | 203 | 78 | | | | ■ | 活套法兰连接 | | Model 型号 | DN | D1 | Do | D2 | A | P | H | n-φc | Dny预抽口 | 法兰标准 | GD-J50 | 50 | 110 | 90 | 55 | 70 | 78 | 203 | 4-φ9 | | GB6070 | GD-J63 | 63 | 130 | 110 | 68 | 88 | 160 | 380 | 4-φ9 | | GD-J80 | 80 | 145 | 125 | 85 | 98 | 160 | 400 | 8-φ9 | | GD-J100 | 100 | 165 | 145 | 105 | 108 | 160 | 420 | 8-φ9 | | GD-J(S)160 | 160 | 225 | 200 | 165 | 158 | 160 | 575 | 8-φ11 | DN40 GB4982 | GD-J(S)200 | 200 | 285 | 260 | 208 | 200 | 160 | 655 | 12-φ11 | DN50 GB6070 | GD-J(S)250 | 250 | 335 | 310 | 258 | 208 | 250 | 690 | 12-φ11 | DN63 GB6070 | GD-J(S)320 | 320 | 425 | 395 | 328 | 250 | 250 | 785 | 12-φ14 | DN80 GB6070 | GD-J(S)150 | 150 | 220 | 195 | 156 | 158 | 160 | 575 | 8-φ12 | DN40 GB4982 | JB919 | GD-J(S)300 | 300 | 380 | 350 | 308 | 250 | 250 | 785 | 8-φ14 | DN80 GB6070 | JB919 | | | |
