寶德導(dǎo)控制帶伺服活塞電磁閥/進口BURKERT電磁閥
寶德導(dǎo)控制帶伺服活塞電磁閥采用次開閥和二次開閥連在體，主閥和導(dǎo)閥分步使電磁力和壓差直接開啟主閥口。當(dāng)線圈通電時，產(chǎn)生電磁力使動鐵芯和靜鐵芯吸合，導(dǎo)閥口開啟而導(dǎo)閥口設(shè)在主閥口上，且動鐵芯與主閥芯連在起，此時主閥上腔的壓力通過導(dǎo)閥口卸荷，在壓力差和電磁力的同時作用下使主閥芯向上運動，開啟主閥介質(zhì)流通。當(dāng)線圈斷電時電磁力消失，此時動鐵芯在自重和彈簧力的作用下關(guān)閉導(dǎo)閥孔，此時介質(zhì)在平衡孔中進入主閥芯上腔，使上腔壓力升高，此時在彈簧復(fù)位和壓力的作用下關(guān)閉主閥，介質(zhì)斷流。結(jié)構(gòu)合理，動作可靠，在零壓差時工作也可靠。如：ZQDF，ZS，2W等。寶德導(dǎo)控制帶伺服活塞電磁閥由導(dǎo)閥和主閥芯著形成通道組合而成；常閉型在未通電時，呈關(guān)閉狀態(tài)。當(dāng)線圈通電時，產(chǎn)生的磁力使動鐵芯和靜鐵芯吸合，導(dǎo)閥口打開，介質(zhì)流向出口，此時主閥芯上腔壓力減少，低于進口側(cè)的壓力，形成壓差克服彈簧阻力而隨之向上運動，達到開啟主閥口的目的，介質(zhì)流通。當(dāng)線圈斷電時，磁力消失，動鐵芯在彈簧力作用下復(fù)位關(guān)閉導(dǎo)口，此時介質(zhì)從平衡孔流入，主閥芯上腔壓力增大，并在彈簧力的作用下向下運動，關(guān)閉主閥口。
