进口常闭电磁阀

美国米勒(MILLER)品牌进口常闭电磁阀当线圈通电时卧苛寿,先导阀芯吸合乱伞潘,先导孔打开穿,阀上腔卸压婪刺寥,活塞靠下腔介质压力推动逛,电磁阀打开;当线圈断电时榷鳖,先导阀芯靠弹簧复位么,先导孔关闭匈浪髓,阀上腔由活塞节流孔增压和复位弹簧的推力沸芥贸,电磁阀关闭钢哥。广泛应用在航天改平、船舶重工小、石油化工架、给排水菲川、消防设备某母、食品医疗设备龚、清洗设备戈和律、景观喷灌不抢稿、加湿设备惨、液压设备松想胆、测试设备某、水厂等,工作压力在0100MPa的管道系统中目。

产品特点肺戏:

工作原理谐:
常闭杏奉:当线圈通电时坷弓渤,先导阀芯吸合跺浑,先导孔打开熄惦,阀上腔卸压功现撤,活塞靠下腔介质压力推动畅济逛,电磁阀打开;当线圈断电时卢蔼,先导阀芯靠弹簧复位醚,先导孔关闭十,阀腔由活塞节流孔增压和复位弹簧的推力徘浆,电磁阀关闭斤圃。
常开弹是碗:当线圈通电时虫媒氨,先导孔关闭愁玫,阀上腔由活塞节流孔增压和复位弹簧的推力门加鳖,电磁阀关闭蚂俗。当线圈断电时乓拈继,先导阀芯靠弹簧复位称,先导孔打开坪,阀上腔卸压释轿邯,活塞靠下腔介质压力推动救,电磁阀打开拐弟猾。

注祈韦吻:出口端压力大于进口端压力挡,介质会反向导通渤。可安装止回阀或订制自带止回功能的阀恃铂。

Applications: 
Widely used in aerospace, shipbuilding Heavy Industry, petrochemical, water, fire fighting equipment, food and medical equipment, cleaning equipment, landscape irrigation, humidification equipment, hydraulic equipment, testing equipment, water plant, the work pressure in the pipeline 6.4 --- 100MPa system.

Features: 
Spool is stainless steel piston and piston rings will not be stuck impurities in the medium, dynamic sealing performance and long life; piston valve chamber with the metal does not produce direct friction, the valve installed to the limit; authoritarian coil, easily burned ; for a long time to restart the stopped action, action as sensitive; minimum start working pressure 0.5MPa.

Main technical parameters:

Specifications:

DN0.5 ~ DN200

Body material:

Stainless Steel

Medium:

Water, gas, oil, steam, gas, corrosive fluids

Temperature range:

-100 ~ +200

Media Viscosity:

Less than 50C St (greater than the time to be customized)

Protection performance:

Waterproof, explosion-proof (Exd IICT5), anti-corrosion

Wiring:

Terminal Block Type; lead type; male

Control:

Normally open, normally closed

Power supply voltage:

DC12 ~ 127V; AC36 ~ 380V

Connection:

Thread, flange (male and special interfaces or add custom adapter)

Leakage:

Zero

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 throttle valve chamber pressurized by the piston return spring and 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, the piston on the lower chamber medium pressure to promote the solenoid valve open.

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.

电磁阀控制方式选择痹颅:

常闭型电磁阀指线圈断电时狮,电磁阀关闭;线圈通电时炯襄矾,电磁阀打开驶。

常开型电磁阀指线圈断电时咖垒必,深圳名阀电磁阀打开;线圈通电时控吵,电磁阀关闭疙湍。

我们可以根据持续工作时间长短来选择峦寺败:常闭瓣绒、常开仟瓮、或可持续通电

1躬恍、当电磁阀需要长时间关闭练码,并且关闭的时间多于开启的时间应选用常闭型贿巧。

2危、当电磁阀需要长时间开启沛萄,并且开启的时间多于关闭的时间应选用常开型安千头。

3庙倍、需要长时间开启的同时又要长时间关闭时阔仍,要选自保持式电磁阀毛矾窖,也叫常开常闭型电磁阀勒盘担。

4弘闺食、但是有些用于安全保护的工况萄浅疟,如炉活、窑火焰监测败沃渐,则不能选常开的胸妨,应选可长期通电型贫哩纤。

5爬敦妈、用于燃气警报系统涩,要选用常开型的燃气紧急切断电磁阀茹皑,带手动开启兰。
