4、電源條件
1）根據(jù)供電電源種類，分別選用交流和直流電磁閥。一般來(lái)說(shuō)交流電源取用方便；
2）電壓規(guī)格用盡量?jī)?yōu)先選用AC220V.DC24V；
3）電源電壓波動(dòng)通常交流選用+%10%.-15%，直流允許±%10左右，如若超差，須采取穩(wěn)壓措施；
4）應(yīng)根據(jù)電源容量選擇額定電流和消耗功率。須注意交流起動(dòng)時(shí)VA值較高，在容量不足時(shí)應(yīng)優(yōu)先選用間接導(dǎo)式電磁閥。

減壓閥的作用原理是靠閥內(nèi)流道對(duì)水流的局部阻力降低水壓，水壓降的范圍由連接閥瓣的薄膜或活塞兩側(cè)的進(jìn)出口水壓差自動(dòng)調(diào)節(jié)。定比減壓原理是利用閥體中浮動(dòng)活塞的水壓比控制，進(jìn)出口端減壓比與進(jìn)出口側(cè)活塞面積比成反比。這種減壓閥工作平穩(wěn)無(wú)振動(dòng)；閥體內(nèi)無(wú)彈簧，故無(wú)彈簧銹蝕、金屬疲勞失效之慮；密封性能良好不滲漏，因而既減動(dòng)壓（水流動(dòng)時(shí)）又減靜壓（流量為0時(shí)）；特別是在減壓的同時(shí)不影響水流量。
