長(zhǎng)期大量批發(fā)smc氣缸磁性開關(guān)先導(dǎo)式電磁閥：

原理：通電時(shí)，電磁力把先導(dǎo)孔打開，上腔室壓力迅速下降，在關(guān) 電磁閥閉件周圍形成上低下高的壓差，流體壓力推動(dòng)關(guān)閉件向上移動(dòng)，閥門打開；斷電時(shí)，彈簧力把先導(dǎo)孔關(guān)閉，入口壓力通過旁通孔迅速腔室在關(guān)閥件周圍形成下低上高的壓差，流體壓力推動(dòng)關(guān)閉件向下移動(dòng)，關(guān)閉閥門。

特點(diǎn)：流體壓力范圍上限較高，可任意安裝（需定制）但必須滿足流體壓差條件。

電磁閥從閥結(jié)構(gòu)和材料上的不同與原理上的區(qū)別，分為六個(gè)分支小類：

直動(dòng)膜片結(jié)構(gòu)、分步直動(dòng)膜片結(jié)構(gòu)、先導(dǎo)膜片結(jié)構(gòu)、直動(dòng)活塞結(jié)構(gòu)、分步直動(dòng)活塞結(jié)構(gòu)、先導(dǎo)活塞結(jié)構(gòu)。
