閥對(duì)流量的控制可以分為兩種:
一種是開(kāi)關(guān)控制:要么全開(kāi)、要么全關(guān),流量要么zui大、要么zui小,沒(méi)有中間狀態(tài),如普通的電磁直通閥、電磁換向閥、電液換向閥。
另一種是連續(xù)控制:閥口可以根據(jù)需要打開(kāi)任意一個(gè)開(kāi)度,由此控制通過(guò)流量的大小,這類閥有手動(dòng)控制的,如節(jié)流閥,也有電控的,如比例閥、伺服閥。
所以使用比例閥或伺服閥的目的就是:以電控方式實(shí)現(xiàn)對(duì)流量的節(jié)流控制(當(dāng)然經(jīng)過(guò)結(jié)構(gòu)上的改動(dòng)也可實(shí)現(xiàn)壓力控制等),既然是節(jié)流控制,就必然有能量損失,伺服閥和其它閥不同的是,它的能量損失更大一些,因?yàn)樗枰欢ǖ牧髁縼?lái)維持前置級(jí)控制油路的工作。
