产品简介: |
DDC-JQ | | ■ | DDC-JQ型-电磁真空带充气阀 | | | ■ | DDC-JQ型电磁真空带充气阀是机械真空泵安全阀,安装于机械真空泵的进气口,并与泵同步开启和关闭。当泵停止工作或电源突然中断时,阀门自动关闭。使真空系统保持真空并将大气充入泵腔内,从而避免泵油逆向流动而污染真空系统。适用介质为纯净空气和非腐蚀性气体。 | | | ■ | DDC-JQ Electro-vacuum Charging Valve | | | ■ | DDC-JQ electro-vacuum charging valve is a safety valve for vacuum, pump. It is mounted at the intake nozzle of vacuum pump, synchronously opened and closed with the vacuum pump. In case that vacuum pump stops working or power supply is suddenly broken off, valve will be cosed automatically to keep the vacuum system vacuum and the air charged into the cavity of vacuum pump, thus to prevent pump oil from reverse flow that can pollute the vacuum system. Applicable medium can be pure air and noncorrosive gases. | | | ■ | 主要技术性能 Main Technical Performance | | | ■ ■ ■ | 适用范围:Applicability | 105~10-2Pa | 阀门漏率:Valve Leak Rate | ≤6.7×10-3Pa.L/S. | 适用温度:Applicability | -30~+50℃ | 线围温升:Coil Temperature Rise | ≤65℃ | 开闭时间:Open-close Time | ≤3S | 电源电压:Mains Voltage | 220V/50Hz | | | | ■ | 主要零件材料 Materials of Main Parts | | | ■ ■ | 阀体、阀盖、阀板:碳钢或铝合金 密封圈:丁腈橡胶 Body, bonnet and disc: carbon steel or aluminium alloy Seal ring: NBR | | | CONSTRUCTION FIGHTS(mm) | | ■ | 外形及连接尺寸(mm)(JB919) Overall and Connection Dimensions(mm) | | | Model 型号 | DN | h | B | H | D | Do | D1 | n-d | Machineal pump 机械泵匹配参考 | DDC-JQ16 | 16 | 28 | 48 | 176 | 68 | 42 | 22 | 4-M5 | 2XZ-0.5~1 | DDC-JQ25 | 25 | 35 | 58 | 199 | 82 | 55 | 29 | 4-M6 | 2XZ-2~4 | DDC-JQ32 | 32 | 40 | 68 | 222 | 92 | 64 | 36 | 4-M6 | 2XZ-4 | DDC-JQ40 | 40 | 44 | 80 | 253 | 110 | 70 | 44 | 4-M6 | 2XZ-8 | DDC-JQ50 | 50 | 56 | 94 | 294 | 124 | 90 | 55 | 4-M8 | 2X-15 | DDC-JQ65 | 65 | 65 | 115 | 320 | 135 | 105 | 70 | 4-M8 | 2X-30 | DDC-JQ80 | 80 | 75 | 140 | 367 | 165 | 125 | 85 | 4-M8 | 2X-70 | | |
