进口超低温电磁阀

美国米勒(MILLER)品牌簧朵鳖: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橙狗犀,是设备系统控制中气体氢、液体男、油类等各种管道介质的自动化控制琳施下,实现节能和程序控制自动化忻驶羡。是自动控制系统中常见的管路开关元件握,被广泛使用于冷冻库豹、石油化工道、暖通空调诗、消防貉沥梆、冶金澳佩拧、纺织磁、船舶重工哩艇、环保及其他各工业部门的管路装置中力淮。

产品特点推锭操:

1佳荤馁、采用原装密封材料辱羡及,寿命是同类产品十倍

2将踩亢、数控机床加工皑测泞,确保电磁阀的精度与可靠性

3奉、液体杭效、气体毕缅、油品可混合使用孙坟,提高阀的使用范围

4盎托、采用专用塑封线圈圈很,提高阀的可靠性并能防水斧桥、防潮

5童剧、现场可自由安装;动作响应迅速;阀体采用热锻成型工艺笑、外型美观

6碍泰、活塞环用特殊耐低温琅恳、耐磨材料制作;活塞与金属阀腔不产生直接摩擦喝姆,阀体安装方向无限制;特制线圈协炔抠,不易    烧毁;长时间停止动作重新启动闭收,作同样灵敏

7赁、安装提示梯:最好线圈竖直向上离陪死,也可根据需要任意安装

主要技术参数玖匹:

产品规格缚间跋:

DN0.5DN100

阀体材质掂恍稿:

不锈钢

适用介质点踩:

液氮便陪琅、气承浑呛、油桂嘘吭、蒸汽秘、腐蚀流体等

温度范围僧寂购:

-200+150

介质粘度捆晤冷:

小于50C St(大于时需定制)

防护性能誓枫潘:

防潮譬、防爆(Exd IICT5)绣肚硷、防腐

接线方式啸履踏:

接线座式;引线式;插头式

控制方式唯烩:

常开聊伐、常闭

电源电压霓:

DC24127V; AC36380V

连接方式瑟蹬脱:

内螺纹秆、法兰(外螺纹和特殊接口可定做或加转接头)

工作原理顷莱藤:
常闭亭拇渺:当线圈通电时脯零竭,先导阀芯吸合棺,先导孔打开拷倒澎,阀上腔卸压体劣械,活塞靠下腔介质压力推动彤田婆,电磁阀打开;当线圈断电时凸禽,先导阀芯靠弹簧复位姜落勺,先导孔关闭五剃幻,阀上腔由活塞节流孔增压和复位弹簧的推力裴算捎,电磁阀关闭圭。
常开擂诲陪:当线圈通电时痛,先导孔关闭串,阀上腔由活塞节流孔增压和复位弹簧的推力铃陛帕,电磁阀关闭乒。当线圈断电时惕曝涣,先导阀芯靠弹簧复位筋,先导孔打开搬,阀上腔卸压杠耽镐,活塞靠下腔介质压力推动拿禄,电磁阀打开抵掸。

注风朵揭:出口端压力大于进口端压力富迫,介质会反向导通歧祷。可安装止回阀或订制自带止回功能的阀宝娇。

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.
