style="font-size:16px;">近年來的新建建筑多采用一戶一環(huán)的室內(nèi)系統(tǒng)形式，這種形式出現(xiàn)水力失調(diào)的的現(xiàn)象是：有的地方是供熱初、末寒期頂層不熱，供熱的嚴寒期熱。有的地方是供熱初、末寒期底層熱，供熱的嚴寒期不熱。產(chǎn)生這兩種情況的原因往往是供熱系統(tǒng)的循環(huán)流量偏**于設(shè)計流量而溫差小，小于設(shè)計溫差造成的。在供熱的初、末寒期，由于供回水的溫差比較低，低于設(shè)計溫差，頂層用戶很少受溫差動力的影響，流量低于底層用戶，當嚴寒期到來，供熱循環(huán)水的供回水溫差加大，接近了設(shè)計溫差，頂層用戶由于溫差動力增加的影響，流量增加了，所以產(chǎn)生了供熱初、末寒期頂層不熱，供熱的嚴寒期頂層熱和供熱初、末寒期底層熱，供熱的嚴寒底層期不熱的現(xiàn)象。出現(xiàn)這種水力失調(diào)的情況不是很多，一般都是采用加頂層流量的方法解決，即采用逐樓層關(guān)小用戶閥門小的方法進行解決。另外，可以將用戶入口的球型鎖閉閥換成可調(diào)節(jié)式鎖閉閥，其調(diào)節(jié)性能更強一些。當熱計量推廣開來，每戶安裝溫控閥</span><span style="font-size:16px;">后，每戶都具有了自動調(diào)節(jié)功能，這種問題就會基本消除。</span> 武威水力控制閥報價水力控制閥*依靠介質(zhì)———水的能量，即可實現(xiàn)對壓力、流量、液位等的控制。</p><div style="width:100%;text-align: center;"><img style="max-width:

style="font-size:16px;">水力控制閥宜水平安裝。水平安裝時，閥蓋宜向上。消防給水系統(tǒng)的減壓閥閥后應(yīng)有排水設(shè)施。自動噴水滅火系統(tǒng)的需減壓時，減壓閥應(yīng)設(shè)置在報警閥前（沿水流方向），與單個報警閥配套設(shè)置的減壓閥，可不設(shè)備用減壓閥；與多個報警閥配套設(shè)置的減壓閥，應(yīng)設(shè)備廠用減壓閥。用于熱水供應(yīng)工程的減壓閥，應(yīng)采用熱水型減壓閥。采用干管干管循環(huán)方式（半循環(huán)方式）的熱水供應(yīng)工程，減壓閥設(shè)置要求應(yīng)與冷水工程相同；采用立管循環(huán)方式（全循環(huán)方式）的熱水供應(yīng)工程，減壓閥設(shè)置應(yīng)防止熱水循環(huán)的破壞，各分區(qū)回水管在匯合點壓力應(yīng)平衡。在給水系統(tǒng)中經(jīng)常會對水的壓力、流量、液位等參數(shù)進行頻繁的控制。如果都使用外接能源，如氣源或電源的話，將會消耗很大。例如：1)從高壓區(qū)向低壓區(qū)給水的市政供水系統(tǒng)中，</span><span style="font-size:16px;">需要保持下游的壓力穩(wěn)定。2)從壓力較高的增壓泵流出后用于灌溉的灌溉系統(tǒng)中，需要使水源減壓。3)從高壓端向恒定的下游供水的樓宇管網(wǎng)系統(tǒng)中，需要保護整個管路的平穩(wěn)運行，避免受到偶然出現(xiàn)的壓力過大的影響。4)向水塔蓄水的供水系統(tǒng)中，需要控制水位。5)向蓄水區(qū)自動蓄水的消防系統(tǒng)中，需要保證控制區(qū)域液位正常。</span> </p><p> <span style="font-size:16px;">在接近閥瓣的動作加速，易發(fā)生水錘的沖擊，接近全閉時，閥門動作越緩慢越好，于是可在閥瓣上設(shè)置節(jié)流裝置。另外先導(dǎo)閥的節(jié)流和動作部分要盡量避免設(shè)置特小口徑的孔口，以免堵塞。必要時要加過濾網(wǎng)，定期檢修及設(shè)置旁通管路。水力控制閥分隔膜型和活塞型兩類，工作原理相同，都是以上下游壓力差為動力，有導(dǎo)閥控制，使隔膜（活塞）液壓式差動操作，完全由水力自動調(diào)節(jié)，從而使主閥閥瓣完全開啟或完全關(guān)閉或處于調(diào)節(jié)狀態(tài)。可調(diào)式減壓閥：根據(jù)減壓原理和結(jié)構(gòu)型式的不同，能減動壓和靜壓，能夠有效設(shè)定出口壓力，不隨其流量變化而變化的減壓閥分為比例式減壓閥和可調(diào)式減壓閥?？烧{(diào)式減壓閥：根據(jù)減壓原理和結(jié)構(gòu)型式的不同，能減動壓和靜壓，能夠有效設(shè)定出口壓力，不隨其流量變化而變化的減壓閥</span><span
