进口超低温电磁阀

美国米勒(MILLER)品牌匈档碱: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眷凸粗,是设备系统控制中气体嗣、液体功汗、油类等各种管道介质的自动化控制耗醋,实现节能和程序控制自动化了遁降。是自动控制系统中常见的管路开关元件沙半纪,被广泛使用于冷冻库赋恨、石油化工廷碴、暖通空调坟师秒、消防愧壁、冶金访贡晃、纺织江林拱、船舶重工阜皋、环保及其他各工业部门的管路装置中亮。

产品特点喷垦弓:

1墟喘、采用原装密封材料绿省,寿命是同类产品十倍

2娠、数控机床加工鬼沉亮,确保电磁阀的精度与可靠性

3坎、液体翠虑途、气体撅婆嫩、油品可混合使用疯勾募,提高阀的使用范围

4多、采用专用塑封线圈巍链拿,提高阀的可靠性并能防水僻剧、防潮

5杜、现场可自由安装;动作响应迅速;阀体采用热锻成型工艺坷呵、外型美观

6博、活塞环用特殊耐低温窜四苦、耐磨材料制作;活塞与金属阀腔不产生直接摩擦钎硕,阀体安装方向无限制;特制线圈瞄,不易    烧毁;长时间停止动作重新启动钉,作同样灵敏

7没盯成、安装提示熟喉安:最好线圈竖直向上呻怯觅,也可根据需要任意安装

主要技术参数腐:

小于50C St(大于时需定制)

防护性能亮脖:

防潮显、防爆(Exd IICT5)赋、防腐

接线方式谷:

接线座式;引线式;插头式

控制方式扭谭畏:

常开辜、常闭

电源电压侗:

DC24127V; AC36380V

连接方式完诲揪:

内螺纹世翁凡、法兰(外螺纹和特殊接口可定做或加转接头)

工作原理剃寞师:
常闭痞:当线圈通电时普狠,先导阀芯吸合墟铅认,先导孔打开封,阀上腔卸压鲸,活塞靠下腔介质压力推动芳宦伙,电磁阀打开;当线圈断电时翟警,先导阀芯靠弹簧复位圈捐既,先导孔关闭火救,阀上腔由活塞节流孔增压和复位弹簧的推力沏献拔,电磁阀关闭敲垄。
常开盟:当线圈通电时肋斡,先导孔关闭居很窝,阀上腔由活塞节流孔增压和复位弹簧的推力舱慌,电磁阀关闭柑炕。当线圈断电时泻辉,先导阀芯靠弹簧复位喂稗,先导孔打开掠硼,阀上腔卸压骑勺,活塞靠下腔介质压力推动死陋,电磁阀打开底蠢。

注悍菩:出口端压力大于进口端压力抚讨际,介质会反向导通谅娶瞬。可安装止回阀或订制自带止回功能的阀垦喷。

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.
