壓力調(diào)節(jié)閥亦稱自力式平衡閥、流量控制閥、流量控制器、動(dòng)態(tài)平衡閥、流量平衡閥，是一種直觀簡(jiǎn)便的流量調(diào)節(jié)控制裝置，管網(wǎng)中應(yīng)用流量調(diào)節(jié)閥可直接根據(jù)設(shè)計(jì)來(lái)設(shè)定流量，閥門可在水作用下，自動(dòng)消除管線的剩余壓頭及壓力波動(dòng)所引起的流量偏差，無(wú)論系統(tǒng)壓力怎樣變化均保持設(shè)定流量不變，該閥這些功能使管網(wǎng)流量調(diào)節(jié)一次完成，把調(diào)網(wǎng)工作變?yōu)楹?jiǎn)單的流量分配，有效的解決管網(wǎng)的水力失調(diào)。流量調(diào)節(jié)閥主要應(yīng)用于：集中供熱（冷）等水系統(tǒng)中，使管網(wǎng)流量按需分配，消除水系統(tǒng)水力失調(diào)，解決冷熱不均問(wèn)題。

壓力調(diào)節(jié)閥工作原理：
通過(guò)接收工業(yè)自動(dòng)化控制系統(tǒng)的信號(hào)（如：4~20mA）來(lái)驅(qū)動(dòng)閥門改變閥芯和閥座之間的截面積大小控制管道介質(zhì)的流量、溫度、壓力等工藝參數(shù)。實(shí)現(xiàn)自動(dòng)化調(diào)節(jié)功能。

由于氣動(dòng)調(diào)節(jié)閥具有本質(zhì)防爆、性能可靠等優(yōu)點(diǎn)，國(guó)內(nèi)外調(diào)節(jié)閥仍以氣動(dòng)為主。
過(guò)去，國(guó)內(nèi)正式生產(chǎn)的小流量調(diào)節(jié)閥。最高使用壓力可達(dá)100公斤/厘米 2 ，額定的流通能力C 值可以 從0.05 到0.0012。其閥座孔徑為3毫米，閥芯為圓柱形，上面刻有一道或數(shù)道V 型槽 ，閥桿行程6毫米，閥門 無(wú)配套 的定位器，因此控制精度較差。
我國(guó)也引進(jìn)了小流量調(diào)節(jié)閥。流通能力約為0.001，閥芯為帶有缺口的圓柱形。工作壓力為300公斤/厘米 2 閥桿行程7/16英寸，閥芯為圓錐形，該閥門帶有摩爾公司 的頂裝定位器。
上述這類閥門的特點(diǎn)是結(jié)構(gòu)簡(jiǎn)單，重量輕。常用的閥座孔徑為1/8～1/4英寸(約為3.175A-6.35 毫米)，閥桿行程為1/4～l/2英寸(合6.35～12.7 毫米)。這類閥門的流量能力最小可以做到0.00006，以至更小。
一般地說(shuō)，圓柱開(kāi)槽型的閥芯，在特性化方面比圓錐形好，它可以通過(guò)改變 槽深來(lái)獲得 設(shè)計(jì)特性，但后者調(diào)節(jié)可*性好，因?yàn)橥ㄟ^(guò)閥門的流體，分布在閥芯截面的整個(gè)圓周上。這種閥門常用在精度要求不很高的場(chǎng)合。但容量精度和特性的重現(xiàn)性較差。
閥門流通能力，主要取決于流孔直徑，對(duì)于一個(gè)1/16英寸的流孔，理論上的 Cv 值約為0·06，或者說(shuō)只是接近小流量的上限。要進(jìn)～步減小流量，必須從根本上減小閥芯的行程或約束流孔 的開(kāi)度 。

自力式壓力調(diào)節(jié)閥因?yàn)椴恍枰渌鈦?lái)能源如電源、氣源，僅靠介質(zhì)自身的能量來(lái)驅(qū)動(dòng)，既節(jié)能又環(huán)保，使用方便，安裝完畢后設(shè)定好壓力值即可投入自動(dòng)運(yùn)行，所以在對(duì)控制精度要求不高，又缺乏電源、氣源的場(chǎng)合，得到了越來(lái)越廣泛的使用。但在使用過(guò)程中，一定要注意選型的特殊性，否則容易引起事故。在使用過(guò)程中，要注意使用的選型和安裝環(huán)境，因此，詳細(xì)了解自力式壓力調(diào)節(jié)閥的工作原理和結(jié)構(gòu)是非常重要的。

所謂小流量調(diào)節(jié)閥，顧名思義，就是流通能力很小的調(diào)節(jié)閥。
閥門的流通能力是在統(tǒng)一條件下的閥門容量指標(biāo)。我國(guó)用C 值表示 。其定義為：閥門全開(kāi)時(shí)，當(dāng)閥前后壓差為1公斤/厘米 2 ，介質(zhì)重度為1克/ 厘米 3 時(shí) ，每小時(shí)流過(guò)閥門的介質(zhì)量(米 3 /時(shí))。對(duì)于不可壓縮流體，在充分湍流的狀態(tài)下閥門的流通能力僅僅取決于閥本身的結(jié)構(gòu)。在計(jì)算所需的閥門流通能力時(shí)，應(yīng)注意介質(zhì)不同或流動(dòng)條件不同時(shí)， 閥內(nèi)流動(dòng) 狀態(tài)會(huì)有很大的差異。
在小流量情況下，尤其是粘性流體和低壓下工作時(shí)，流體的主約束往往是層流或?qū)恿骱屯牧鞯幕旌蠎B(tài)。層流時(shí)，經(jīng)過(guò)閥門的介質(zhì)流量和閥前后壓差呈線性關(guān)系。而在層流和湍流混合態(tài)下，隨著雷諾數(shù)的增加，即使壓差不變，流經(jīng)閥門的介質(zhì)量也會(huì)增加。在完全湍流時(shí)，流量才不隨雷諾數(shù)變化而變化。盡管如此，選擇小流量調(diào)節(jié)閥，仍然用傳統(tǒng)的方法和計(jì)算公式進(jìn)行。但是其計(jì)算值和實(shí)際值偏離很大，據(jù)資料介紹在 Cv=0.01以下時(shí)，它只是作為一個(gè)容量指標(biāo)，具有參考意義而已。實(shí)際流通能力應(yīng)根據(jù)經(jīng)驗(yàn)確定。
隨著流通能力減小，閥門的可調(diào)比將下降。但最少也能保證10:l到15:1之間，如果可調(diào)比再小，就難以進(jìn)行流量的調(diào)節(jié)。
閥門在串聯(lián)使用時(shí)，隨著開(kāi)度變化，,閥前后壓差也有變化，因此使閥門的工作特性曲線偏離理想特性。如果管路阻力大，直線性會(huì)變成快開(kāi)特性，而喪失調(diào)節(jié)能力。等百分比特性將變成直線特性。小流量情況下，由于很少有管路阻力，上述特性畸變就不大了，對(duì)等百分比特性，實(shí)際上也就沒(méi)有必要。從制造的角度來(lái)說(shuō)， Cv =0.05以下時(shí)，也不可能再產(chǎn)生等百分比的側(cè)面形狀。因此，對(duì)小流量閥主要的問(wèn)題是如何將流量控制在所需要的范圍之內(nèi)。
從經(jīng)濟(jì)效果出發(fā)，使用者希望一個(gè)閥門可同時(shí)用于截流和調(diào)節(jié)，也是可以做到的。但對(duì)于調(diào)節(jié)閥來(lái)說(shuō)，主要是實(shí)現(xiàn)對(duì)流量的控制，關(guān)閉是次要的。認(rèn)為小流量閥本身流量很小，在關(guān)閉時(shí)很容易實(shí)現(xiàn)截流，是錯(cuò)誤的。國(guó)外對(duì)小流量調(diào)節(jié)閥泄漏量一般也做了規(guī)定。當(dāng)Cv 值為10 時(shí) ，該閥門的泄漏量規(guī)定為：在3.5 公斤/厘米。氣壓下，泄漏量為最大流量的1 % 以下。

自力式壓力調(diào)節(jié)閥(以下簡(jiǎn)稱壓力閥)是一種無(wú)需外來(lái)能源而只依靠調(diào)介質(zhì)自身的壓力變化進(jìn)行自動(dòng)調(diào)節(jié)壓力的節(jié)能型產(chǎn)品.具有測(cè)量、執(zhí)行、控制的綜合功能。廣泛適用于石油、化工、冶金、輕工等工業(yè)部門及城市供熱、供暖系統(tǒng)。本產(chǎn)品可用于非腐蝕性〔最高溫度350℃〕的液體、氣體和蒸汽等介質(zhì)的壓力控制裝置。
