ASCO先导式通用电磁阀有弹簧式和杆式两大类。另外还有冲量式Burkert 0255型直动式柱塞电磁阀、先导式电磁阀、安全切换阀、安全解压阀、静重式安全阀等。弹簧式安全阀主要依靠弹簧的作用力而工作,弹簧式安全阀中又有封闭和不封闭的,一般易燃、易爆或有毒的介质应选用封闭式,蒸汽或惰性气体等可以选用不封闭式,在弹簧式安全阀中还有带扳手和不带扳手的。扳手的作用主要是检查阀瓣的灵活程度,有时也可以用作手动紧急泄压用。杠杆式安全阀主要依靠杠杆重锤的作用力而工作,但由于杠杆式安全阀体积庞大往往限制了选用范围。温度较高时选用带散热器的安全阀。
ASCO先导式通用电磁阀是由电磁线圈和磁芯组成,是包含一个或几个孔的阀体。当线圈通电或断电时,磁芯的运转将导致流体通过阀体或被切断,以达到改变流体方向的目的。电磁阀的电磁部件由固定铁芯、动铁芯、线圈等部件组成;阀体部分由滑阀芯、滑阀套、弹簧底座等组成。电磁线圈被直接安装在阀体上,阀体被封闭在密封管中,构成一个简洁、紧凑的组合。我们在生产中常用的电磁阀有二位三通、二位四通、二位五通等。这里先说说二位的含义:对于电磁阀来说就是带电和失电,对于所控制的阀门来说就是开和关。我们制氧机仪控系统中,二位三通电磁阀用的zui多,它在生产中可用来接通或切断气 源,从而对气动控制膜头气路进行切换。它由阀体、阀罩、电磁组件、弹簧及密封结构等部件组成,动铁芯底部的密封块借助弹簧的压力将阀体进气口关闭。通电后,电磁铁吸合,动铁芯上部带弹簧的密封块把排气口关闭,气流从进气口进入膜头,起到控制作用。
