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。
4V系列二位五通电磁阀
4V系列二位五通电磁阀
主要分类
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。
2、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。
3、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。
2、按照材质上可以分为三大类
1)不锈钢电磁阀:是常见的电磁阀产品,不锈钢材质因为,工作稳定,为受用户欢迎。
电磁阀
电磁阀
*该系列产品地应用于纺织、印刷、化工、塑料、橡胶、制药、食品、建材、机械、电器、表面处理等生产和科研部门以及浴室、食堂、空调等人们日常生活设施中
2)黄铜电磁阀:部分要求不高的用户,会选择黄铜电磁阀产品,此类电磁阀产品相对偏低,适应于普通的工作环境。
* 该系列产品一般适应于液体、水、气、热水、油、瓦斯等介质。
3)塑料电磁阀:在一些工作场所,和用在特殊介质的电磁阀,例如有酸碱性介质的工作环境,黄铜和不锈钢材质的电磁阀产品均容易被腐蚀,所以用特殊材质(工程塑料PVC、 CPVC、UPVC、ABS或聚四氟等)做成的塑料电磁阀在性能上特别,
该系列产品适应于适宜饮用水、各类未经处理的污水、雨水、海水及各种酸碱盐溶液、有机溶剂等
2、电磁阀根据作用可分为开关式电磁阀和比例式电磁阀
1)、开关式电磁阀,即起开关作用,当有电流流过时,电磁阀控制线路或油路通断。
2)、比例式电磁阀,即根据输入的电流大小不同,输出的压力不同,当改变输入电流时,即可改变电磁阀输出压力,多用于液压系统。
选型注意
选型依据
电磁阀选型首先应该依次遵循安全性,可靠性,适用性,经济性四大原 则,其次是根据六个方面的现场工况(即管道参数、流体参数、压力参数、电气参数、动作方式、特殊要求进行选择)。
选型依据:
1、根据管道参数选择电磁阀的:通径规格(即DN)、接口方式
1)按照现场管道内径尺寸或流量要求来确定通径(DN)尺寸;
2)接口方式,一般>DN50要选择法兰接口,≤DN50则可根据用户需要自由选择。
2、根据流体参数选择电磁阀的:材质、温度组
1)腐蚀性流体:宜选用电磁阀和全不锈钢;食用超净流体:宜选用食品级不锈钢材质电磁阀;
2)高温流体:要选择采用的电工材料和密封材料制造的电磁阀,而且要选择活塞式结构类型的;
电磁阀
电磁阀
3)流体状态:大至有气态,液态或混合状态,特别是口径大于DN25时一定要区分开来;
4)流体粘度:通常在50cSt以下可任意选择,若超过此值,则要选用高粘度电磁阀。
3、根据压力参数选择电磁阀的:原理和结构品种
1)公称压力:这个参数与其它通用阀门的含义是一样的,是根据管道公称压力来定;
2)工作压力:如果工作压力低则必须选用直动或分步直动式原理;工作压差在0.04Mpa以上时直动式、分步直动式、先导式均可选用。
4、电气选择:电压规格应尽量优先选用AC220V、DC24较为方便。
5、根据持续工作时间长短来选择:常闭、常开、或可持续通电
1)当电磁阀需要长时间开启,并且持续的时间多于关闭的时间应选 用常开型;
2)要是开启的时间短或开和关的时间不多时,则选常闭型;
3)但是有些用于安全保护的工况,如炉、窑火焰监测,则不能选常开的,应选可长期通电型。
6、根据环境要求选择辅助功能:防爆、止回、手动、防水雾、水淋、潜水。
