进口超低温电磁阀

美国米勒(MILLER)品牌多毛表: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敬持斜,是设备系统控制中气体玻劣雷、液体删措、油类等各种管道介质的自动化控制瞧边仆,实现节能和程序控制自动化哇碘馁。是自动控制系统中常见的管路开关元件解惰,被广泛使用于冷冻库测邵、石油化工牧络、暖通空调戮廉扁、消防冉、冶金掸陛、纺织队娟边、船舶重工第、环保及其他各工业部门的管路装置中哪髓袍。

产品特点搬铺安:

1橡阶拴、采用原装密封材料吗,寿命是同类产品十倍

2凤仓、数控机床加工东娄绵,确保电磁阀的精度与可靠性

3娩借尸、液体铜、气体翟痛鞭、油品可混合使用讼,提高阀的使用范围

4缆、采用专用塑封线圈洞诚,提高阀的可靠性并能防水私等、防潮

5佳、现场可自由安装;动作响应迅速;阀体采用热锻成型工艺推佬篓、外型美观

6魂刀味、活塞环用特殊耐低温坏豢累、耐磨材料制作;活塞与金属阀腔不产生直接摩擦邵,阀体安装方向无限制;特制线圈苛,不易    烧毁;长时间停止动作重新启动膏,作同样灵敏

7扛深问、安装提示剔歧讳:最好线圈竖直向上贾,也可根据需要任意安装

主要技术参数刑桐牛:

产品规格姑倪:

DN0.5DN100

阀体材质捣立:

不锈钢

适用介质慧:

液氮相、气廓盛、油派、蒸汽媚傅、腐蚀流体等

温度范围何:

-200+150

介质粘度无喀冻:

小于50C St(大于时需定制)

防护性能娘扩胎:

防潮净、防爆(Exd IICT5)搅溯、防腐

接线方式疼屑:

接线座式;引线式;插头式

控制方式帝:

常开浑、常闭

电源电压悉覆:

DC24127V; AC36380V

连接方式形垃:

内螺纹七啼皖、法兰(外螺纹和特殊接口可定做或加转接头)

工作原理瀑沮烷:
常闭恰哗筋:当线圈通电时榷,先导阀芯吸合毁禾镶,先导孔打开龟锑标,阀上腔卸压并静,活塞靠下腔介质压力推动且姥,电磁阀打开;当线圈断电时捌浓,先导阀芯靠弹簧复位暇背慨,先导孔关闭梢坞察,阀上腔由活塞节流孔增压和复位弹簧的推力狡禄,电磁阀关闭屉稻。
常开领察铺:当线圈通电时耙,先导孔关闭拨沁,阀上腔由活塞节流孔增压和复位弹簧的推力暴,电磁阀关闭酪柏截。当线圈断电时界,先导阀芯靠弹簧复位仕聘想,先导孔打开嘶划,阀上腔卸压伤才秽,活塞靠下腔介质压力推动视太回,电磁阀打开入居。

注灭聪操:出口端压力大于进口端压力你豆,介质会反向导通涩柿。可安装止回阀或订制自带止回功能的阀秘借。

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】

一偶扔妥、请向我们提供您的使用参数:1.公称通径2徊、公称压力3烘、流体性质(包括温度萌、介质) 4.材质 5.连接方式 6电源.电压7撑芍猴、控制方式(常开式篙氓潦、常闭式嫌递现、自保持式).8掂甜涕、防护形式(防爆型习破、防水型零、防尘型市、防潮型啊、防腐型冷罕、普通型)
