原理:通電時(shí),電磁線圈產(chǎn)生電磁力把關(guān)閉件從閥座上提起,閥門(mén)打開(kāi);斷電時(shí),電磁力消失,彈簧把關(guān)閉件壓在閥座上,閥門(mén)關(guān)閉。
特點(diǎn):在真空、負(fù)壓、零壓時(shí)能正常工作,但通徑一般不超過(guò)25mm。
2)分步直動(dòng)式REXROTH電磁閥:
原理: 它是一種直動(dòng)和先導(dǎo)式相結(jié)合的原理,當(dāng)入口與出口沒(méi)有壓差時(shí),通電后,電磁力直接把先導(dǎo)小閥和主閥關(guān)閉件依次向上提起,閥門(mén)打開(kāi)。當(dāng)入口與出口達(dá)到啟動(dòng)壓差時(shí),通電后,電磁力先導(dǎo)小閥,主閥下腔壓力上升,上腔壓力下降,從而利用壓差把主閥向上推開(kāi);斷電時(shí),先導(dǎo)閥利用彈簧力或介質(zhì)壓力推動(dòng)關(guān)閉件,向下移動(dòng),使閥門(mén)關(guān)閉。
特點(diǎn): 在零壓差或真空、高壓時(shí)亦能可*動(dòng)作,但功率較大,要求必須水平安裝。
3)先導(dǎo)式REXROTH電磁閥:
原理:通電時(shí),電磁力把先導(dǎo)孔打開(kāi),上腔室壓力迅速下降,在關(guān) REXROTH電磁閥閉件周?chē)纬缮系拖赂叩膲翰?,流體壓力推動(dòng)關(guān)閉件向上移動(dòng),閥門(mén)打開(kāi);斷電時(shí),彈簧力把先導(dǎo)孔關(guān)閉,入口壓力通過(guò)旁通孔迅速腔室在關(guān)閥件周?chē)纬上碌蜕细叩膲翰睿黧w壓力推動(dòng)關(guān)閉件向下移動(dòng),關(guān)閉閥門(mén)。
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。
2.REXROTH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(lèi):
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)。
