进口超低温电磁阀

美国米勒(MILLER)品牌漓慰: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嵌,是设备系统控制中气体港、液体模、油类等各种管道介质的自动化控制拇,实现节能和程序控制自动化遂惭骇。是自动控制系统中常见的管路开关元件姬,被广泛使用于冷冻库稼晶、石油化工瘫虎、暖通空调悲挺、消防烷、冶金帅径、纺织底、船舶重工秃溜链、环保及其他各工业部门的管路装置中擞染疼。

产品特点潘瞄:

1十、采用原装密封材料切岗似,寿命是同类产品十倍

2核篡凄、数控机床加工阀,确保电磁阀的精度与可靠性

3炮、液体棉、气体另、油品可混合使用航环擎,提高阀的使用范围

4险巾井、采用专用塑封线圈赌,提高阀的可靠性并能防水兴、防潮

5滇、现场可自由安装;动作响应迅速;阀体采用热锻成型工艺嘛烦拔、外型美观

6轰绦蓄、活塞环用特殊耐低温点狄皇、耐磨材料制作;活塞与金属阀腔不产生直接摩擦碘故氓,阀体安装方向无限制;特制线圈泞,不易    烧毁;长时间停止动作重新启动淌,作同样灵敏

7氨策逗、安装提示童寒:最好线圈竖直向上脑,也可根据需要任意安装

主要技术参数洼崇吩:

产品规格凡杜:

DN0.5DN100

阀体材质势涣裙:

不锈钢

适用介质丧稿眠:

液氮椒拢、气惹、油杯械魔、蒸汽荚丰、腐蚀流体等

温度范围的耪:

-200+150

介质粘度肚:

小于50C St(大于时需定制)

防护性能捷缉:

防潮悄侣疾、防爆(Exd IICT5)钝兼土、防腐

接线方式帛俩哀:

接线座式;引线式;插头式

控制方式双肉换:

常开祥母、常闭

电源电压溜蕊犯:

DC24127V; AC36380V

连接方式回充:

内螺纹敬挤靠、法兰(外螺纹和特殊接口可定做或加转接头)

工作原理绞敞巫:
常闭固忿:当线圈通电时浅技攀,先导阀芯吸合丛,先导孔打开扔,阀上腔卸压视互绦,活塞靠下腔介质压力推动幻,电磁阀打开;当线圈断电时哗帮,先导阀芯靠弹簧复位石,先导孔关闭好晾,阀上腔由活塞节流孔增压和复位弹簧的推力侧窜,电磁阀关闭豪。
常开蔬修咕:当线圈通电时轮,先导孔关闭阿年赐,阀上腔由活塞节流孔增压和复位弹簧的推力脐瓶边,电磁阀关闭娶。当线圈断电时污,先导阀芯靠弹簧复位哎牌,先导孔打开搜,阀上腔卸压泪,活塞靠下腔介质压力推动白守驴,电磁阀打开白呈。

注路淌:出口端压力大于进口端压力百史,介质会反向导通潍柒。可安装止回阀或订制自带止回功能的阀浅。

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】

一窍捷、请向我们提供您的使用参数:1.公称通径2丹粉、公称压力3填焚、流体性质(包括温度检拘、介质) 4.材质 5.连接方式 6电源.电压7恼素、控制方式(常开式筋、常闭式瓷是、自保持式).8藉吕、防护形式(防爆型嗅诺建、防水型栋趴、防尘型五、防潮型捷据、防腐型哀、普通型)
