进口超低温电磁阀

美国米勒(MILLER)品牌路念: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离悔,是设备系统控制中气体叼、液体迪奔、油类等各种管道介质的自动化控制谅,实现节能和程序控制自动化舌罕。是自动控制系统中常见的管路开关元件律阮,被广泛使用于冷冻库彩工憾、石油化工椿窟补、暖通空调谈檀、消防桶肮帕、冶金轻纫、纺织莱赖、船舶重工琳矾、环保及其他各工业部门的管路装置中阂贺。

产品特点嗓:

1僵叙母、采用原装密封材料逛,寿命是同类产品十倍

2素、数控机床加工鲸射辆,确保电磁阀的精度与可靠性

3渤庭、液体雷地、气体吹情歇、油品可混合使用方扔拔,提高阀的使用范围

4嫡翠炉、采用专用塑封线圈丘,提高阀的可靠性并能防水柑戚、防潮

5襄、现场可自由安装;动作响应迅速;阀体采用热锻成型工艺捎、外型美观

6翻、活塞环用特殊耐低温规、耐磨材料制作;活塞与金属阀腔不产生直接摩擦勾,阀体安装方向无限制;特制线圈尚涵究,不易    烧毁;长时间停止动作重新启动素唬虱,作同样灵敏

7阔盟苏、安装提示鹅:最好线圈竖直向上讣送墒,也可根据需要任意安装

主要技术参数苦:

产品规格轰棱碍:

DN0.5DN100

阀体材质扛矾:

不锈钢

适用介质楷疏鸡:

液氮睫秃宋、气散妈、油寄浚瓶、蒸汽啡、腐蚀流体等

温度范围排:

-200+150

介质粘度羌:

小于50C St(大于时需定制)

防护性能忱:

防潮牌故圣、防爆(Exd IICT5)阔挟那、防腐

接线方式挞舵但:

接线座式;引线式;插头式

控制方式胶句芦:

常开昂、常闭

电源电压心改署:

DC24127V; AC36380V

连接方式奈:

内螺纹救海凶、法兰(外螺纹和特殊接口可定做或加转接头)

工作原理唤搁:
常闭途麻:当线圈通电时栋藕,先导阀芯吸合九妮论,先导孔打开阔袭,阀上腔卸压内什灯,活塞靠下腔介质压力推动泉,电磁阀打开;当线圈断电时杆边掣,先导阀芯靠弹簧复位孩,先导孔关闭切氢仕,阀上腔由活塞节流孔增压和复位弹簧的推力粗,电磁阀关闭辅。
常开鹃吞:当线圈通电时腐嘶,先导孔关闭艾烫,阀上腔由活塞节流孔增压和复位弹簧的推力弹,电磁阀关闭肖辈。当线圈断电时剁迁边,先导阀芯靠弹簧复位庐舒度,先导孔打开勺败髓,阀上腔卸压无想阔,活塞靠下腔介质压力推动桅挖,电磁阀打开溪。

注琉溺:出口端压力大于进口端压力喊掣,介质会反向导通荤横书。可安装止回阀或订制自带止回功能的阀孤。

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.
