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萍世,先导阀芯吸合飘,先导孔打开屑嫡畏,阀上腔卸压咖疮,活塞靠下腔介质压力推动架凭戒,电磁阀打开;当线圈断电时毫,先导阀芯靠弹簧复位朗,先导孔关闭派,阀上腔由活塞节流孔增压和复位弹簧的推力起特裳,电磁阀关闭楼。广泛应用在航天形览、船舶重工圃、石油化工普农、给排水凭、消防设备帅郴妮、食品医疗设备媚混、清洗设备酚、景观喷灌豢、加湿设备避、液压设备垛侯乔、测试设备磋绢船、水厂等,工作压力在0100MPa的管道系统中菏跨法。

量洪舷:

工作原理丝:
常闭光戏:当线圈通电时康穷,先导阀芯吸合梆抚,先导孔打开郡规,阀上腔卸压汞靖雀,活塞靠下腔介质压力推动稠,电磁阀打开;当线圈断电时杀都蘑,先导阀芯靠弹簧复位供甸来,先导孔关闭廊陶陵,阀腔由活塞节流孔增压和复位弹簧的推力捂须,电磁阀关闭忙舱。
常开世场喊:当线圈通电时挝嵌,先导孔关闭湘恒,阀上腔由活塞节流孔增压和复位弹簧的推力救笑繁,电磁阀关闭绿亲。当线圈断电时口胃,先导阀芯靠弹簧复位帝挞,先导孔打开法惶溪,阀上腔卸压黑衫鄙,活塞靠下腔介质压力推动仕经,电磁阀打开航却系。

注睬购:出口端压力大于进口端压力莲纶莱,介质会反向导通想。可安装止回阀或订制自带止回功能的阀咆履纶。

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:

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疲舅羌:

常闭型电磁阀指线圈断电时千邵赦,电磁阀关闭;线圈通电时棠,电磁阀打开冈泻绊。

常开型电磁阀指线圈断电时伦,深圳名阀电磁阀打开;线圈通电时讨,电磁阀关闭村诽鹤。

我们可以根据持续工作时间长短来选择唬玩:常闭丘强、常开改、或可持续通电

1晨堆、当电磁阀需要长时间关闭极阶淡,并且关闭的时间多于开启的时间应选用常闭型鞭。

2衬、当电磁阀需要长时间开启杭,并且开启的时间多于关闭的时间应选用常开型士改。

3狮、需要长时间开启的同时又要长时间关闭时己,要选自保持式电磁阀兄靠镶,也叫常开常闭型电磁阀讲沃。

4卢、但是有些用于安全保护的工况恒眠,如炉嫌抡、窑火焰监测陌,则不能选常开的腻,应选可长期通电型曙。

5取狗庆、用于燃气警报系统奇橡抨,要选用常开型的燃气紧急切断电磁阀惶仕宽,带手动开启妹。
