工作原理: 常閉:當(dāng)線圈通電時(shí),先導(dǎo)閥芯吸合,先導(dǎo)孔打開(kāi),閥上腔卸壓,活塞靠下腔介質(zhì)壓力推動(dòng),電磁閥打開(kāi);當(dāng)線圈斷電時(shí),先導(dǎo)閥芯靠彈簧復(fù)位,先導(dǎo)孔關(guān)閉,閥上腔由活塞節(jié)流孔增壓和復(fù)位彈簧的推力,電磁閥關(guān)閉。 常開(kāi):當(dāng)線圈通電時(shí),先導(dǎo)孔關(guān)閉,閥上腔由活塞節(jié)流孔增壓和復(fù)位彈簧的推力,電磁閥關(guān)閉。當(dāng)線圈斷電時(shí),先導(dǎo)閥芯靠彈簧復(fù)位,先導(dǎo)孔打開(kāi),閥上腔卸壓,活塞靠下腔介質(zhì)壓力推動(dòng),電磁閥打開(kāi)。 |
