美国JOUCOMATIC先导式电磁阀,ASCO先导阀
美国JOUCOMATIC先导式电磁阀选用主要控制参数为通径、设计公称压力、介质允许温度范围、接口尺寸等。电磁阀是用电磁铁推动阀门的开启与关闭，通常用于口径在40mm以下的两位式控制中，尤其多用于接通、切断或转换气路、液路等。阀门的密封是考核阀门质量优劣的主要指标之一。阀门的密封主要包括两个方面，即内漏和外漏。内漏是指阀座与关闭件之间对介质达到的密封程度。外漏是指阀杆填料部位的泄露，中口垫片部位的泄露以及阀体因铸造缺陷造成的泄露。外漏是不允许发生的。电磁阀主要优点是体积小，动作可靠，维修方便，价格便宜。选择时需要注意根据工艺要求选择常开或常闭型。电磁阀就是只需瞬间通电即完成阀门开关动作,阀芯位置不需电来保持。
