style="font-size:16px;">某一需要的出口壓力，并依靠介質(zhì)自身的能量，使出口壓力自動(dòng)保持穩(wěn)定的閥門。水用安全閥（泄壓/持壓閥）。當(dāng)給水管路系統(tǒng)中的壓力超過設(shè)定壓力時(shí)，閥門自動(dòng)開啟泄壓，保護(hù)管線安全。</span>

style="font-size:16px;">水力控制減壓閥、先導(dǎo)式減壓閥、可調(diào)式減壓閥不是同一種。水力控制閥就是水壓控制的閥門，水力控制閥由一個(gè)主閥及其附設(shè)的導(dǎo)管﹑導(dǎo)閥﹑針閥﹑球閥和壓力表等組成。根據(jù)使用目的﹑功能及場(chǎng)所的不同可演變成遙控浮球閥﹑減壓閥﹑緩閉止回閥﹑流量控制閥﹑泄壓閥﹑水力電動(dòng)控制閥、水泵控制閥等。水力控制閥前要安裝過濾器，并應(yīng)便于排污的要求。本類閥門在管道中一般應(yīng)當(dāng)水平安裝。水力控制閥是以管道介質(zhì)壓力為動(dòng)力，進(jìn)行啟閉、調(diào)節(jié)的閥門。它由一個(gè)主閥和附設(shè)的導(dǎo)管、針閥、球閥和壓力表等組成、根據(jù)使用的目的、功能場(chǎng)所的不同，可演變成遙控浮球閥、減壓閥、緩閉止回閥、流量控制器、泄壓閥、水力電動(dòng)控制閥、緊急關(guān)閉閥等。導(dǎo)閥隨介質(zhì)的液位和壓力的變化而動(dòng)作，由于導(dǎo)閥種類很多，可以單獨(dú)使用或幾個(gè)組合使用，就可以使主閥獲得對(duì)水位和水壓及流量等進(jìn)行單獨(dú)和復(fù)合調(diào)節(jié)的功能。但主閥閥體類似截止閥，閥門全開時(shí)，其壓力損失比其他閥門要大得</span><span

style="font-size:16px;">各個(gè)單體建筑間的水力失調(diào)是供熱系統(tǒng)中為常見的一種水力失調(diào)，屬于水平失調(diào)。其具體的表現(xiàn)形式為“近端用戶熱、遠(yuǎn)端用戶冷”。產(chǎn)生這一現(xiàn)象的主要原因是由于每個(gè)單體建筑距離熱源的距離不同，造成遠(yuǎn)端用戶與近端用戶的供熱環(huán)路的阻力不同而引發(fā)流量不同、熱量不同。對(duì)于供熱系統(tǒng)的水平失調(diào)，經(jīng)過幾十年的摸索和實(shí)踐，從使用靜態(tài)的節(jié)流裝置如節(jié)流孔板、手動(dòng)調(diào)節(jié)閥、平衡閥，到現(xiàn)在使用的動(dòng)態(tài)節(jié)流裝置如自力式流量控制閥、自立式差壓控制閥，這些產(chǎn)品對(duì)解決水力失調(diào)現(xiàn)象都做出了一定的貢獻(xiàn)。其中，自力式流量控制閥經(jīng)過十幾年的使用，比較符合我國(guó)現(xiàn)階段的供熱實(shí)際情況。我單位經(jīng)過實(shí)地考察，決定使用河北廊坊生產(chǎn)的“愛能牌”自力式流量控制閥，進(jìn)行流量調(diào)節(jié)，消除各個(gè)住宅樓之間的水平失調(diào)。</span><span

style="font-size:16px;">供熱系統(tǒng)水力失調(diào)的分析系統(tǒng)水力失調(diào)可分為水平失調(diào)和垂直失調(diào)兩種。前者表現(xiàn)為水平面上用戶流量偏離設(shè)計(jì)值，導(dǎo)致近、遠(yuǎn)端冷熱不均；后者表現(xiàn)為供暖系統(tǒng)各立管之間、各層之間存在水力不平衡，導(dǎo)致樓層上下冷熱不均。供熱系統(tǒng)水力失調(diào)是普遍存在的問題。主要原因存在于：其一，設(shè)計(jì)中供熱外網(wǎng)水力計(jì)算不準(zhǔn)確，只注意到不利點(diǎn)（通常在系統(tǒng)的末端）必需的自用壓頭，而其他點(diǎn)的自用壓頭總是大于計(jì)算值，越接近熱源的位置自用壓頭就越大。而各環(huán)路自身又不具備自主水力調(diào)節(jié)功能，必然要出現(xiàn)流量分配偏離設(shè)計(jì)狀態(tài)，導(dǎo)致用戶冷熱不均的水力失調(diào)現(xiàn)象。（通常是近端過熱、遠(yuǎn)端不熱）其二，在系統(tǒng)設(shè)計(jì)合理的情況下，水泵選型過大，運(yùn)行流量偏離設(shè)計(jì)狀態(tài)（大流量小溫差），也導(dǎo)致系統(tǒng)的水力失調(diào)。其三，新用戶的增加和供熱外網(wǎng)的擴(kuò)建，卻沒有及時(shí)改造校核，而只是更換水泵（加大水泵的流量和揚(yáng)程）使系統(tǒng)的運(yùn)行調(diào)節(jié)和管理更為復(fù)雜，造成新的水力失調(diào)。通常設(shè)置大流量、高揚(yáng)程水泵，采用大流量小溫差這種方式并不能解決水力失調(diào)現(xiàn)象。據(jù)有關(guān)資料介紹，大流量小溫差的運(yùn)行方式將會(huì)使系統(tǒng)投資增加20％以上，耗費(fèi)熱能15％-20％，多耗電能30％以上。</span>
