NUMATICS电磁阀L11BB452B000060
电磁阀它是一种直动和先导式相结合的原理,当入口与出口没有压差时,通电后,电磁力直接把先导小阀和主阀关闭件依次向上提起,阀门打开。当入口与出口达到启动压差时,通电后,电磁力先导小阀,主阀下腔压力上升,上腔压力下降,从而利用压差把主阀向上推开;断电时,先导阀利用弹簧力或介质压力推动关闭件,向下移动,使关闭。

电磁阀特点:在零压差或真空、高压时亦能可动作,但功率较大,要求必须水平安装。先导式:原理:通电时,电磁力把先导孔打开,上腔室压力迅速下降,在关闭件周围形成上低下高的压差,流体压力推动关闭件向上移动,打开;断电时,弹簧力把先导孔关闭,入口压力通过旁通孔迅速腔室在关阀件周围形成低上高的压差,流体压力推关闭件向下移动,关闭。
电磁阀由两个基本功能单元组成:电磁线圈和磁芯。包含一个或几个孔的阀体。当电线圈通电或断电时,磁芯的运转将导致流体通过阀体或被切断。电磁线圈被直接安装在阀体上,磁芯被封闭在密封管中,构成一个简洁,紧凑的组合。
在的不同位置开有通孔,每个孔都通向不同的油管,腔中间是阀,两面是两块电磁铁,哪面的磁铁线圈通电阀体就会被吸引到哪边,通过控制阀体的移动来档住或漏出不同的排油的孔,而进油孔是常开的,液压油就会进入不同的排油管,然后通过油的压力来推动油刚的活塞,活塞又带动活塞杆,活塞竿带动机械装置动。这样通过控制电磁铁的电流就控制了机械运动。
