1)外漏堵绝,内漏易控,使用安全。
内外泄漏是危及安全的要素。
其它自控阀通常将阀杆伸出,由电动、气动、液动执行机构控制阀芯的转动或移动。
这都要解决长期动作阀杆动密封的外泄漏难题;唯有电磁阀是用电磁力作用于密封在隔磁套管内的铁芯完成,不存在动密封,所以外漏易堵绝。
电动阀力矩控制不易,容易产生内漏,甚至拉断阀杆头部;电磁阀的结构型式容易控制内泄漏,直至降为零。
所以,电磁阀使用特别安全,尤其适用于腐蚀性、有毒或高低温的介质。
(2)系统简单,便接电脑,价格低谦。
电磁阀本身结构简单,价格也低,比起调节阀等其它种类执行器易于安装维护。
更显著的是所组成的自控系统简单得多,价格要低得多。
由于电磁阀是开关信号控制,与工控计算机连接十分方便。
在当今电脑普及,价格大幅下降的时代,电磁阀的优势就更加明显。
(3)动作快递,功率微小,外形轻巧。
电磁阀响应时间可以短至几个毫秒,即使是先导式电磁阀也可以控制在几十毫秒内。
由于自成回路,比之其它自控阀反应更灵敏。
设计得当的电磁阀线圈功率消耗很低,属节能产品;还可做到只需触发动作,自动保持阀位,平时一点也不耗电。
电磁阀外形尺寸小,既节省空间,又轻巧美观。
(4)调节精度受限,适用介质受限。
电磁阀通常只有开关两种状态,阀芯只能处于两个极限位置,不能连续调节,(力图突破的新构思不少,但还都处于试验试用阶段)所以调节精度还受到一定限制。
电磁阀对介质洁净度有较高要求,含颗粒状的介质不能适用,如属杂质须先滤去。
另外,粘稠状介质不能适用,而且,特定的产品适用的介质粘度范围相对较窄。
(5)型号多样,用途广泛。
电磁阀虽有先天不足,优点仍十分突出,所以就设计成多种多样的产品,满足各种不同的需求,用途极为广泛。
电磁阀技术的进步也都是围绕着如何克服先天不足,如何更好地发挥固有优势而展开。
