Rexroth電磁閥在液路系統(tǒng)中用來(lái)實(shí)現(xiàn)液路的通斷或液流方向的改變,它一般具有一個(gè)可以在線圈電磁力驅(qū)動(dòng)下滑動(dòng)的閥芯,閥芯在不同的位置時(shí),電磁閥的通路也就不同。閥芯的工作位置有幾個(gè),該電磁閥就叫幾位電磁閥:閥體上的接口,也就是電磁閥的通路數(shù),有幾個(gè)通路口,該電磁閥就叫幾通電磁閥。 電磁閥安裝后,一般所有接口都應(yīng)該是連接好了的,所謂工作位置指的是閥芯的位置。閥芯在線圈不通電時(shí)處在甲位置,在線圈通電時(shí)處在乙位置,閥芯在不同位置時(shí),對(duì)各接口起到或接通或封閉的作用。
通用化方向上的發(fā)展
REXROTH電磁閥應(yīng)用十分廣泛,而使用時(shí)情況卻千差萬(wàn)別,增強(qiáng)通用性能降低制造、購(gòu)銷、存貯、安裝、維護(hù)的成本,這方面已邁出了大步。
1、響應(yīng)時(shí)間可調(diào)
給出電信號(hào)到閥芯動(dòng)作完成的時(shí)間稱為響應(yīng)時(shí)間。不同場(chǎng)合希望開(kāi)關(guān)速度不同,有四種組合:快開(kāi)快關(guān)——用于快速反應(yīng)系統(tǒng);快開(kāi)慢關(guān)——用于防止水錘;慢開(kāi)快關(guān)——用于緩啟急斷; 慢開(kāi)慢關(guān)——用于平穩(wěn)過(guò)渡。
2、擴(kuò)展介質(zhì)適用范固
REXROTH電磁閥與其它自控閥不同在于介質(zhì)粘度適用范圍較窄,所以空氣、水、蒸汽、油等介質(zhì)對(duì)于先導(dǎo)型電磁閥其結(jié)構(gòu)參數(shù)是不同的;一般地說(shuō)是不能通用的。而ZDF多功能電磁閥只用一顆小螺釘,卻做到了氣、水、油的通用,而且還使油的粘度適用范圍大大加寬,深受歡迎。
3、開(kāi)度可調(diào)與手動(dòng)兼容
REXROTH電磁閥在使用時(shí)常常還希望它兼具手動(dòng)功能,作為停電或故障時(shí)備用。
一般手動(dòng)裝置只能手動(dòng)開(kāi)閥或手動(dòng)關(guān)閥,二者齊備的稱*手動(dòng)。手動(dòng)裝置還能對(duì)閥門開(kāi)度進(jìn)行預(yù)置,一般手動(dòng)只能對(duì)閥的zui大或zui小開(kāi)度進(jìn)行預(yù)置,而*手動(dòng)能分別對(duì)zui大或zui小開(kāi)度進(jìn)行預(yù)置。
