style="text-indent:25px">由于節(jié)流閥的流量不僅取決于節(jié)流口面積的大小，還與節(jié)流口前后的壓差有關(guān)，閥的剛度小，故只適用于執(zhí)行元件負(fù)載變化很小且速度穩(wěn)定性要求不高的場合。對于執(zhí)行元件負(fù)載變化大及對速度穩(wěn)定性要求高的節(jié)流調(diào)速系統(tǒng)，必須對節(jié)流閥進(jìn)行壓力補(bǔ)償來保持節(jié)流閥前后壓差不變，從而達(dá)到流量穩(wěn)定。當(dāng)節(jié)流閥（即蝴蝶閥）被沉積物所阻礙時(shí)，節(jié)氣門開度值產(chǎn)生紊亂，發(fā)動(dòng)機(jī)不能穩(wěn)定、精確的控制其開度，開度值過低造成啟動(dòng)困難、怠速不穩(wěn)或異常熄火；發(fā)動(dòng)機(jī)加減速時(shí)，節(jié)流閥不能及時(shí)響應(yīng)會(huì)導(dǎo)致加速延遲或突然提速。比例壓力控制閥是一個(gè)新的自力式調(diào)節(jié)閥種類。</p><div
