电磁阀的密封材料目前有三种zui常用的。
NBR 丁晴橡胶(nitrile butadiene rubber)
由丁二烯和丙烯腈经乳液聚合法制得的,丁腈橡胶主要采用低温乳液聚合法生产,耐油性*,耐磨性较高,耐热性较好,粘接力强。其缺点是耐低温性差、耐臭氧性差,电性能低劣,弹性稍低。
此外,它还具有良好的耐水性、气密性及优良的粘结性能。广泛用于制各种耐油橡胶制品、多种耐油垫圈、垫片、套管、软包装、软胶管、印染胶辊、电缆胶材料等,在汽车、航空、石油、复印等行业中成为*的弹性材料。
丁腈橡胶具有优良的耐油性,其耐油性仅次于聚硫橡胶和氟橡胶,并且具有的耐磨性和气密性。丁晴橡胶的缺点是不耐臭氧及芳香族、卤代烃、酮及酯类溶剂,不宜做绝缘材料。
丁腈橡胶主要用于制作耐油制品,如耐油管、胶带、橡胶隔膜和大型油囊等,常用于制作各类耐油模压制品,如O形圈、油封、皮碗、膜片、活门、波纹管等,也用于制作胶板和耐磨零件。
EPDM三元乙丙橡胶(Ethylene-Propylene-Diene Monomer)
三元乙丙橡胶是乙烯、丙烯以及非共轭二烯烃的三元共聚物,1963年开始商业化生产。每年*的消费量是80万吨。EPDMzui主要的特性就是其*的耐氧化、抗臭氧和抗侵蚀的能力。由于三元乙丙橡胶属于聚烯烃家族,它具有*的硫化特性。在所有橡胶当中,EPDM具有zui低的比重。它能吸收大量的填料和油而影响特性不大。因此可以制作成本低廉的橡胶化合物。
分子结构和特性三元乙丙是乙烯、丙烯和非共轭二烯烃的三元共聚物。二烯烃具有特殊的结构,只有两键之一的才能共聚,不饱和的双键主要是作为交链处。另一个不饱和的不会成为聚合物主链,只会成为边侧链。三元乙丙的主要聚合物链是*饱和的。这个特性使得三元乙丙可以抵抗热,光,氧气,尤其是臭氧。三元乙丙本质上是无极性的,对极性溶液和化学物具有抗性,吸水率低,具有良好的绝缘特性。

电磁阀里有密闭的腔,在不同位置开有通孔,每个孔连接不同的油管,腔中间是活塞,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开启或关闭不同的排油孔,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缸的活塞,活塞又带动活塞杆,活塞杆带动机械装置。这样通过控制电磁铁的电流通断就控制了机械运动。
一、电磁阀从原理上分为三大类
1)直动式电磁阀
原理通电时,电磁线圈产生电磁力把关闭件从阀座上提起,阀门打开;断电时,电磁力消失,弹簧把关闭件压在阀座上,阀门关闭。
特点在真空、负压、零压时能正常工作,但通径一般不超过25mm。
2)分步直动式电磁阀
原理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,使阀门关闭。
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。
3)先导式电磁阀
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,阀门打开;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下低上高的压差,流体压力推动关闭件向下移动,关闭阀门。
特点流体压力范围上限较高,可任意安装(需定制)但必须满足流体压差条件。
二、电磁阀从阀结构和材料上的不同与原理上的区别,分为六个分支小类直动膜片结构、分步直动膜片结构、先导膜片结构、直动活塞结构、分步直动活塞结构、先导活塞结构。
三、电磁阀按照功能分类水用电磁阀、蒸汽电磁阀、制冷电磁阀、低温电磁阀、燃气电磁阀、消防电磁阀、氨用电磁阀、气体电磁阀、液体电磁阀、微型电磁阀、脉冲电磁阀、液压电磁阀 常开电磁阀、油用电磁阀、直流电磁阀、高压电磁阀、防爆电磁阀等。
