電磁閥圖(tú)片(piàn)/BURKERT電(diàn)磁閥(fá)參數(shù)
有常(cháng)閉(bì)型和(hé)常(cháng)開型(xíng)二種。常閉(bì)型斷(duàn)電(diàn)時呈關(guān)閉(bì)狀(zhuàng)態，當綫(xiàn)圈(quān)通電時產生電磁(cí)力(lì)，使動(dòng)鐵芯克服彈簧(huáng)力(lì)同靜(jìng)鐵芯(xīn)吸(xī)合直接開啟閥，介(jiè)質(zhì)呈(chéng)通路；當(dāng)綫(xiàn)圈(quān)斷電時電(diàn)磁(cí)力(lì)消(xiāo)失，動鐵芯(xīn)在彈簧(huáng)力的作用(yòng)下復位，直接(jiē)關閉閥(fá)口，介質不通(tōng)。結構簡單(dān)，動(dòng)作(zuò)可靠(kào)，在零壓(yā)差(chà)和微真(zhēn)空下(xià)正常(cháng)工(gōng)作。常(cháng)開型(xíng)正(zhèng)好相反。如(rú)小(xiǎo)於(yú)φ6流量通(tōng)徑(jìng)的(dí)BURKERT電磁(cí)閥。 BURKERT電(diàn)磁(cí)閥采用一(yī)次開閥和(hé)二(èr)次開閥連在一體(tǐ)，主閥和導閥(fá)分步(bù)使電(diàn)磁力(lì)和壓差直接開啟主閥(fá)口。當(dāng)綫(xiàn)圈通電(diàn)時，產(chǎn)生電(diàn)磁力使動(dòng)鐵芯(xīn)和(hé)靜鐵芯吸(xī)合，導閥口(kǒu)開啟(qǐ)而導閥口設在(zài)主閥(fá)口上(shàng)，且動(dòng)鐵(tiě)芯與(yǔ)主閥芯連在一起(qǐ)，此時(shí)主閥上腔的(dí)壓(yā)力通(tōng)過(guò)導(dǎo)閥(fá)口卸(xiè)荷，在壓(yā)力差和電磁力(lì)的同(tóng)時(shí)作用(yòng)下使(shǐ)主閥(fá)芯向上運動，開啟主(zhǔ)閥介質流(liú)通。當綫圈斷電時(shí)電磁力消失，此(cǐ)時(shí)動(dòng)鐵芯在(zài)自重和(hé)彈(dàn)簧力的作(zuò)用下關(guān)閉導閥(fá)孔(kǒng)，此時介質(zhì)在平衡(héng)孔中進(jìn)入主閥芯(xīn)上腔(qiāng)，使(shǐ)上(shàng)腔壓(yā)力升(shēng)高(gāo)，此時在彈簧復位(wèi)和壓(yā)力的(dí)作用下(xià)關閉(bì)主閥(fá)，介(jiè)質斷流(liú)。結(jié)構合(hé)理，動作(zuò)可靠，在(zài)零壓差時工作也(yě)可(kě)靠。如：ZQDF，ZS，2W等。
