像截止閥一樣，流體通過升降式止回閥的通道也是狹窄的，因此通過升降式止回閥的壓力降比旋啟式止回閥大些，而且旋啟式止回閥的流量受到的限制很少。在生產(chǎn)過程中，為了使介質(zhì)的壓力、流量等參數(shù)符合工藝流程的要求，需要安裝調(diào)節(jié)機(jī)構(gòu)對(duì)上述參數(shù)進(jìn)行調(diào)節(jié)。調(diào)節(jié)機(jī)構(gòu)的主要工作原理，是靠改變閥門閥瓣與閥瓣與閥座間的流通面積，達(dá)到調(diào)節(jié)上述參數(shù)的目的。屬于這類閥門的統(tǒng)稱為控制閥，其中分為依靠介質(zhì)本身動(dòng)力驅(qū)動(dòng)的稱為自驅(qū)式控制閥如減壓閥、穩(wěn)壓閥等，凡上來動(dòng)力驅(qū)動(dòng)的（如電力、壓縮空氣和液動(dòng)力）稱為他驅(qū)式控制閥，如電動(dòng)調(diào)節(jié)閥、氣動(dòng)調(diào)節(jié)閥和液動(dòng)調(diào)節(jié)閥等。

圖144所示為定值器的工作原理圖。它由三部分組成：1是直動(dòng)式減壓閥的主閉部分；恒壓降裝置，相當(dāng)于一定差減壓閥。主要作用是使噴嘴得到穩(wěn)定氣源流量；噴嘴擋板裝置和調(diào)壓部分，起調(diào)壓和壓力放大作用，利用被它放大了的氣壓去控制主閥部分。由于定值器具有調(diào)定、比較和放大的功能，因而穩(wěn)壓精度高。定值器處于非工作狀態(tài)時(shí)，由氣源輸入的壓縮空氣經(jīng)過濾器1過濾后進(jìn)入A室和正室。主閥芯19在彈簧2和氣源壓力作用下壓在閥座上，使A室與B室斷開。

為什么擴(kuò)散流的方法更好：起泡點(diǎn)值只是一個(gè)定性的值，從開始起泡到后的群起泡是一個(gè)比較長(zhǎng)的過程，不能準(zhǔn)確的定量。而測(cè)量擴(kuò)散流值是一個(gè)定量值,不但能準(zhǔn)確的確定過濾器的完整性，而且還能反應(yīng)出膜的孔隙率、流量和有效過濾面積等方面的問題，這也就是為什么現(xiàn)在國(guó)外廠家都用擴(kuò)散流法測(cè)試完整性的原因。水侵入法測(cè)試原理：水侵入法專用于疏水性濾芯的測(cè)試，疏水性膜抗拒水，孔徑越小，把水?dāng)D入疏水膜中需要的壓力越大。所以在一定的壓力下，測(cè)量擠入濾膜中的水流量來判斷濾芯的孔徑。
