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)計值，導(dǎo)致近、遠端冷熱不均；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)計中供熱外網(wǎng)水力計算不準確，只注意到不利點（通常在系統(tǒng)的末端）必需的自用壓頭，而其他點的自用壓頭總是大于計算值，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、遠端不熱）其二，在系統(tǒng)設(shè)計合理的情況下，水泵選型過大，運行流量偏離設(shè)計狀態(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)的擴建，卻沒有及時改造校核，而只是更換水泵（加大水泵的流量和揚程）使系統(tǒng)的運行調(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，大流量小溫差的運行方式將會使系統(tǒng)投資增加20％以上，耗費熱能15％-20％，多耗電能30％以上。</span>

水利控制閥就是水壓控制的閥門，水力控制閥由一個主閥及其附設(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﹑水力電動控制閥、水泵控制閥等。減壓閥由主閥、導(dǎo)閥、針閥、球閥、微型過濾器和壓力表組成水力控制接管系統(tǒng)。使用時，當調(diào)定出口壓力后，能自動保持穩(wěn)定出口壓力。本產(chǎn)品利用導(dǎo)閥自力控制，不需要其它裝置和能源，保養(yǎng)簡便，壓力控制準確度高，受進口壓力和流量影響小，減壓穩(wěn)壓可靠。本系列閥門產(chǎn)品用于高層建筑、生活區(qū)等供水管網(wǎng)系統(tǒng)及城市供水工程。當閥門從進口端給水時，水流過針閥進入主閥控制室，出口壓力通過導(dǎo)管作用到導(dǎo)閥上。當出口壓力高于導(dǎo)閥彈簧設(shè)定值時，導(dǎo)閥關(guān)閉。控制室停止排水，此時主閥控制室內(nèi)壓力升高并關(guān)閉主閥，出口壓力不再升高。當閥門出口壓力降到導(dǎo)閥彈簧設(shè)定壓力時，導(dǎo)閥開啟，控制室向下游排水。由于導(dǎo)閥系統(tǒng)排水量大于針閥的進水量，主閥控制室壓力下降。進口壓力使主閥開啟。在穩(wěn)定狀態(tài)下，控制室進水、排水相同，主閥開度不變，出口壓力穩(wěn)定。</span>
