DYC-JQ电磁真空压差阀 电磁真空阀 不锈钢真空阀门 铸钢真空阀
产品说明
上泉真空阀门 商品名称：电磁真空带充气压差阀 DYCJQ ■ DYCJQ型－电磁真空带充气压差阀 ■ DYCJQ型电磁真空带充气压差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，阀门利用大气压力使阀板自动关闭，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。 ■ DYCJQ Electrovacuum Differential Pressure Valve ■ DYCJQ electrovacuum differential Pressure valve is a safely valve for mechanical vacuum pump. It is mounted at take nozzle mechanical vacuum pump, synchronously opened closed h pump. In case that pump stops workg or power supply is suddenly broken f, valve disc will be closed automatically under atmospheric pressure, to keep vacuum system vacuum air charged to pump cavity, thus to prevent pump oil from reverse flow that can pollute vacuum system. Applicable medium can be pure air or noncorrosive gases. ■ 主要技术性能 Ma Technical Performance ■ ■ ■ 适用范围：Applicability 105～102Pa 阀门漏率：Valve Leak Rate ≤1.3×102Pa.L/S. 适用温度：Applicable Temperature 30～+50℃ 线围温升：Coil Temperature Rise ≤65℃ 开闭时间：Openclose Time ≤3S 电源电压：Mas Voltage 220V/50Hz ■ 主要零件材料 Materials Ma Parts ■ ■ 阀体、阀盖、阀板：碳钢或铝合金隔膜：丁腈橡胶加涤纶绸 Body, bonnet disc: carbon steel or alumium alloy Diaphragm: NBR terylene silk CTRUCTION FIGHTS (mm) ■ 外形及连接尺寸(mm) Overall Connection Dimensions(mm) ■ 活套法兰连接(GB6070 图一) Model 型号 DN Do D D2 nφc A H DYCJQ50 50 90 110 55 4φ9 70 203 DYCJQ63 63 105 130 68 4φ9 88 226 DYCJQ80 80 125 145 85 8φ9 98 260 DYCJQ100 100 φ9 108 282 DYCJQ25 165 8φ12 158 350 ■ 快卸法兰连接(GB4982 图二) Model 型号 DN D1 D A H B DYCJQ16 16 17.2 30 40 160 55 DYCJQ25 25 26.2 40 50 170 60 DYCJQ32 32 34.2 55 58 179 60 DYCJQ40 40 41.2 55 65 187 70 DYCJQ50 50 52.2 75 70 203 85 ■ 方体螺纹连接(JB919 图三) Model 型号 DN Do D2 h B H nd DYCJQ8 48 148 4M5 DYCJQ25 25 55 29 35 58 155 4M6 DYCJQ32 32 64 36 40 68 160 4M6 DYCJQ40 40 70 44 44 80 166 4M6 DYCJQ50 50 90 55 56 94 189 4M8 DYCJQ65 65 105 70 65 115 205 4M8 DYCJQ80 80 125 85 75 140 250 4M8
