进口超低温电磁阀

美国米勒(MILLER)品牌关琶啥: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匡掀,是设备系统控制中气体竣龚、液体搜潮、油类等各种管道介质的自动化控制捞抄,实现节能和程序控制自动化檀蹦搁。是自动控制系统中常见的管路开关元件锌,被广泛使用于冷冻库拜、石油化工何快、暖通空调凸、消防峦、冶金统诡、纺织谷、船舶重工寇范宿、环保及其他各工业部门的管路装置中爬第。

产品特点努八:

1俏、采用原装密封材料屡刹谭,寿命是同类产品十倍

2落盆破、数控机床加工仿纫体,确保电磁阀的精度与可靠性

3露、液体呻辰、气体频爽列、油品可混合使用尾须懦,提高阀的使用范围

4偷、采用专用塑封线圈妹输捌,提高阀的可靠性并能防水俄、防潮

5垢绿、现场可自由安装;动作响应迅速;阀体采用热锻成型工艺闪降、外型美观

6炼缆穆、活塞环用特殊耐低温船宫虐、耐磨材料制作;活塞与金属阀腔不产生直接摩擦陆丘苛,阀体安装方向无限制;特制线圈究,不易    烧毁;长时间停止动作重新启动棚,作同样灵敏

7辈技、安装提示骇灌恢:最好线圈竖直向上把,也可根据需要任意安装

主要技术参数猾镐光:

DC24127V; AC36380V

连接方式攻瓮趁:

内螺纹楞券娘、法兰(外螺纹和特殊接口可定做或加转接头)

工作原理赏店藤:
常闭檀:当线圈通电时炔田店,先导阀芯吸合甲内,先导孔打开鳖蓟翠,阀上腔卸压堑抱斧,活塞靠下腔介质压力推动捍,电磁阀打开;当线圈断电时庭蓖,先导阀芯靠弹簧复位腊拣殴,先导孔关闭迁霖腿,阀上腔由活塞节流孔增压和复位弹簧的推力壕,电磁阀关闭拌渺成。
常开赡捎健:当线圈通电时么骚唤,先导孔关闭圈钞,阀上腔由活塞节流孔增压和复位弹簧的推力窜汉,电磁阀关闭吹桑。当线圈断电时炼埃,先导阀芯靠弹簧复位吓扫钝,先导孔打开理培布,阀上腔卸压存,活塞靠下腔介质压力推动挝,电磁阀打开歉喝井。

注河洼:出口端压力大于进口端压力幕,介质会反向导通耪幢么。可安装止回阀或订制自带止回功能的阀淡蛊。

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.
