进口超低温电磁阀

美国米勒(MILLER)品牌伎:进口超低温液氮电磁阀|-196℃电磁阀主要使用于制冷剂,液态二氧化碳,液氨,液氧,液氮,氟里昂等低温流体的管路上钮,是设备系统控制中气体氰、液体腾、油类等各种管道介质的自动化控制哦痴毒,实现节能和程序控制自动化劳。是自动控制系统中常见的管路开关元件湃,被广泛使用于冷冻库我瓢屯、石油化工纤乾、暖通空调搔瞧、消防惫、冶金雄谷激、纺织颠礁搔、船舶重工坦、环保及其他各工业部门的管路装置中工。

产品特点钾辆:

1烁邻、采用原装密封材料煌美,寿命是同类产品十倍

2第俯归、数控机床加工竟,确保电磁阀的精度与可靠性

3滴钞、液体催、气体唇踏陛、油品可混合使用头,提高阀的使用范围

4疤犁、采用专用塑封线圈炼,提高阀的可靠性并能防水校透嵌、防潮

5礁、现场可自由安装;动作响应迅速;阀体采用热锻成型工艺围牵苍、外型美观

6颧、活塞环用特殊耐低温芯层、耐磨材料制作;活塞与金属阀腔不产生直接摩擦泰暴,阀体安装方向无限制;特制线圈究屑康,不易    烧毁;长时间停止动作重新启动焊晤靡,作同样灵敏

7诞筏、安装提示归动分:最好线圈竖直向上殿晌,也可根据需要任意安装

主要技术参数教炔啦:

产品规格痹健:

DN0.5DN100

阀体材质五:

不锈钢

适用介质题壁啪:

液氮络肥唱、气凹、油炭、蒸汽陀、腐蚀流体等

温度范围潭革焦:

-200+150

介质粘度成蔚:

小于50C St(大于时需定制)

防护性能茬辛仿:

防潮筷、防爆(Exd IICT5)林、防腐

接线方式旦:

接线座式;引线式;插头式

控制方式纪醚磁:

常开潦拼、常闭

电源电压娟梆耍:

DC24127V; AC36380V

连接方式躬:

内螺纹许、法兰(外螺纹和特殊接口可定做或加转接头)

工作原理咳:
常闭鸡:当线圈通电时晒幌,先导阀芯吸合锋,先导孔打开离牵,阀上腔卸压体赫,活塞靠下腔介质压力推动宫湾彻,电磁阀打开;当线圈断电时炉阶,先导阀芯靠弹簧复位倡笑逼,先导孔关闭骋霸凉,阀上腔由活塞节流孔增压和复位弹簧的推力泼复,电磁阀关闭但辉抨。
常开炬刀坛:当线圈通电时蹋细,先导孔关闭酱曙,阀上腔由活塞节流孔增压和复位弹簧的推力段,电磁阀关闭褪伤嗜。当线圈断电时袖,先导阀芯靠弹簧复位磕昂,先导孔打开洽撩,阀上腔卸压簧狡邢,活塞靠下腔介质压力推动家,电磁阀打开定可。

注伴镐:出口端压力大于进口端压力铆晦箱,介质会反向导通边佃适。可安装止回阀或订制自带止回功能的阀朽请。

Applications: 
It is widely used in aerospace, shipbuilding Heavy Industry, chemical, refrigeration equipment, Medical equipment, food refrigeration piping systems.

Features: 
Spool is stainless steel piston, piston ring with a special low temperature resistant, wear-resistant material; the piston and the metal does not produce direct friction valve chamber, valve mounting direction unlimited; special coil, not easy to burn; a long time to stop action to re-start, for the same sensitivity.

Main technical parameters:

Specifications:

DN0.5DN100 DN0.5 ~ DN100

Body material:

Stainless Steel

Medium:

Liquid nitrogen, gas, oil, steam, corrosive fluids

Temperature range:

-200 ~ +150 

Media Viscosity:

Less than 50C St (greater than the time to be customized)

Protection performance:

Moisture-proof, explosion-proof (Exd IICT5), anti-corrosion

Wiring:

Terminal Block Type; lead type; male

Control:

Normally open, normally closed

Power supply voltage:

DC24 ~ 127V; AC36 ~ 380V

Connection:

Thread, flange (male and special interfaces or add custom adapter)

How it works: 
NC: When the coil is energized, the pilot spool pull the pilot hole to open, pressure relief valve on the chamber, the piston on the lower chamber medium pressure to promote, the electromagnetic valve is opened; When the coil power, the pilot valve by the spring return, pilot hole closed, the valve chamber and pressurized by the piston return spring throttle thrust, the electromagnetic valve is closed. 
Normally Open: When the coil is energized, the pilot hole closed, the valve chamber and pressurized by the piston return spring throttle thrust, the electromagnetic valve is closed. When the coil power, the pilot valve by the spring return, pilot hole open, pressure relief valve on the chamber, medium pressure piston push the lower chamber, the electromagnetic valve is opened.

Note: The outlet pressure is greater than the inlet pressure, the media will pass anti-wizard. Can be installed or custom built non-return valve function of the valve.

【订货须知】
