調(diào)速閥,是由有定差減壓閥和節(jié)流閥串聯(lián)而成,是進(jìn)行了壓力補(bǔ)償?shù)墓?jié)流閥。
節(jié)流閥用來(lái)調(diào)節(jié)通過(guò)的流量,定差減壓閥則自動(dòng)補(bǔ)償負(fù)載變化的影響,使節(jié)流閥前后的壓差為定值,消除了負(fù)載變化對(duì)流量的影響。
節(jié)流閥前、后的壓力分別引到減壓閥閥芯右、左兩端,當(dāng)負(fù)載壓力增大,于是作用在減壓閥芯左端的液壓力增大,閥芯右移,減壓口加大,壓降減小,從而使節(jié)流閥的壓差(p2-p3)保持不變;反之亦然。這樣就是調(diào)速閥的流量恒定不變(不受負(fù)載影響)。
調(diào)速閥也可以設(shè)計(jì)成先節(jié)流后減壓的結(jié)構(gòu)。
