溫度控制閥簡稱溫控閥是(shi)流量(liang)(liang)調(diao)節閥在溫(wen)(wen)度(du)(du)(du)控(kong)(kong)(kong)制領(ling)域(yu)的(de)典型應用,其基本原理:通過控(kong)(kong)(kong)制換(huan)熱器、空調(diao)機組或其他(ta)用熱、冷設(she)備、一次熱(冷)媒入口流量(liang)(liang),以達到控(kong)(kong)(kong)制設(she)備出口溫(wen)(wen)度(du)(du)(du)。當負荷產生(sheng)變化時,通過改變閥門開啟度(du)(du)(du)調(diao)節流量(liang)(liang),以消除(chu)負荷波(bo)動造成的(de)影響,使溫(wen)(wen)度(du)(du)(du)恢復至設(she)定值。
溫(wen)控(kong)閥(fa)的結(jie)構(gou)及任務原理
用戶室復內的溫度控制是經過散熱器恒溫控制閥來完成的。散熱器恒溫控制閥是由恒溫控制器、流量(liang)調(diao)節閥(fa)(fa)(fa)以(yi)及一(yi)對連(lian)接件(jian)組成(cheng)(cheng),其中(zhong)恒(heng)溫(wen)(wen)(wen)(wen)(wen)(wen)控制(zhi)(zhi)(zhi)器(qi)(qi)(qi)(qi)的(de)(de)核心部件(jian)是傳感器(qi)(qi)(qi)(qi)單(dan)元,即溫(wen)(wen)(wen)(wen)(wen)(wen)包(bao)。溫(wen)(wen)(wen)(wen)(wen)(wen)包(bao)可以(yi)感應(ying)四周環境(jing)溫(wen)(wen)(wen)(wen)(wen)(wen)度的(de)(de)變化(hua)而發生體(ti)(ti)積(ji)變化(hua),帶(dai)動(dong)(dong)調(diao)節閥(fa)(fa)(fa)閥(fa)(fa)(fa)芯發生位(wei)移,進而調(diao)理散熱(re)器(qi)(qi)(qi)(qi)的(de)(de)水(shui)量(liang)來改(gai)動(dong)(dong)散熱(re)器(qi)(qi)(qi)(qi)的(de)(de)散熱(re)量(liang)。恒(heng)溫(wen)(wen)(wen)(wen)(wen)(wen)閥(fa)(fa)(fa)設定溫(wen)(wen)(wen)(wen)(wen)(wen)度可以(yi)人為調(diao)理,恒(heng)溫(wen)(wen)(wen)(wen)(wen)(wen)閥(fa)(fa)(fa)會按(an)設定要(yao)求(qiu)(qiu)自動(dong)(dong)控制(zhi)(zhi)(zhi)和調(diao)理散熱(re)器(qi)(qi)(qi)(qi)的(de)(de)水(shui)量(liang),從(cong)而來到達控制(zhi)(zhi)(zhi)室(shi)(shi)(shi)內(nei)溫(wen)(wen)(wen)(wen)(wen)(wen)度的(de)(de)目(mu)的(de)(de)。溫(wen)(wen)(wen)(wen)(wen)(wen)控制(zhi)(zhi)(zhi)閥(fa)(fa)(fa)普通是裝(zhuang)在散熱(re)器(qi)(qi)(qi)(qi)前,經(jing)過自動(dong)(dong)調(diao)理流量(liang),完成(cheng)(cheng)居民需(xu)求(qiu)(qiu)的(de)(de)室(shi)(shi)(shi)溫(wen)(wen)(wen)(wen)(wen)(wen)。溫(wen)(wen)(wen)(wen)(wen)(wen)控閥(fa)(fa)(fa)有(you)二通溫(wen)(wen)(wen)(wen)(wen)(wen)控閥(fa)(fa)(fa)和三通溫(wen)(wen)(wen)(wen)(wen)(wen)控閥(fa)(fa)(fa)之分。用于(yu)(yu)雙(shuang)管零(ling)(ling)碎(sui)的(de)(de)二通溫(wen)(wen)(wen)(wen)(wen)(wen)控閥(fa)(fa)(fa)阻力較(jiao)大(da);用于(yu)(yu)單(dan)管系統的(de)(de)阻力較(jiao)小。溫(wen)(wen)(wen)(wen)(wen)(wen)控閥(fa)(fa)(fa)的(de)(de)感溫(wen)(wen)(wen)(wen)(wen)(wen)包(bao)與閥(fa)(fa)(fa)體(ti)(ti)普通組裝(zhuang)成(cheng)(cheng)一(yi)個全(quan)體(ti)(ti),感溫(wen)(wen)(wen)(wen)(wen)(wen)包(bao)自身(shen)即是現場室(shi)(shi)(shi)內(nei)溫(wen)(wen)(wen)(wen)(wen)(wen)度傳感器(qi)(qi)(qi)(qi)。假如(ru)需(xu)求(qiu)(qiu),可以(yi)采用近(jin)程(cheng)溫(wen)(wen)(wen)(wen)(wen)(wen)度傳感器(qi)(qi)(qi)(qi);近(jin)程(cheng)溫(wen)(wen)(wen)(wen)(wen)(wen)度傳感器(qi)(qi)(qi)(qi)置于(yu)(yu)要(yao)求(qiu)(qiu)控溫(wen)(wen)(wen)(wen)(wen)(wen)的(de)(de)房(fang)間,溫(wen)(wen)(wen)(wen)(wen)(wen)控閥(fa)(fa)(fa)閥(fa)(fa)(fa)體(ti)(ti)置于(yu)(yu)供暖系統上的(de)(de)某一(yi)部位(wei)。三通溫(wen)(wen)(wen)(wen)(wen)(wen)控閥(fa)(fa)(fa)次要(yao)用于(yu)(yu)帶(dai)有(you)跨越管的(de)(de)單(dan)管系統,其分流系數可以(yi)在0~100%的(de)(de)范圍內(nei)變化(hua),流量(liang)調(diao)理余地大(da),但價(jia)錢比(bi)擬貴(gui),構造(zao)較(jiao)復(fu)雜。二通溫(wen)(wen)(wen)(wen)(wen)(wen)控閥(fa)(fa)(fa)有(you)的(de)(de)zd用于(yu)(yu)雙(shuang)管零(ling)(ling)碎(sui),有(you)的(de)(de)用于(yu)(yu)單(dan)管系統。
