ZZWP自力式溫度調節閥產品特點

本閥(fa)無需電或壓縮空氣(qi)等外界能(neng)源,可(ke)靠.感溫液體膨脹均勻(yun),比例式調節(jie)控(kong)制,控(kong)制精(jing)度(du)高,工作(zuo)穩定(ding),有效節(jie)約(yue)能(neng)源,平(ping)衡式閥(fa)體設(she)計,使閥(fa)能(neng)在更大(da)壓差下工作(zuo),線性或等百比流量(liang)特性,溫度(du)設(she)定(ding)操作(zuo)簡單方(fang)(fang)便,體積小,重量(liang)輕,安裝方(fang)(fang)便.

ZZWP自力式溫度調節閥工作原理

自力(li)式(shi)溫(wen)(wen)(wen)度調(diao)節(jie)閥(fa)(fa)按(an)作(zuo)用(yong)(yong)形式(shi)可分(fen);加熱(re)用(yong)(yong)溫(wen)(wen)(wen)控(kong)(kong)型,冷(leng)卻用(yong)(yong)溫(wen)(wen)(wen)控(kong)(kong)型,合流(分(fen)流)溫(wen)(wen)(wen)度調(diao)節(jie)型.是利用(yong)(yong)感溫(wen)(wen)(wen)液體(ti)(ti)受熱(re)膨脹,遇冷(leng)收(shou)縮及液體(ti)(ti)不可壓縮的原(yuan)理進行調(diao)節(jie).將(jiang)溫(wen)(wen)(wen)度傳感器插入需要(yao)控(kong)(kong)制溫(wen)(wen)(wen)度的介質(zhi)(zhi)(zhi)中,當(dang)介質(zhi)(zhi)(zhi)溫(wen)(wen)(wen)度升(sheng)高(gao)時,感受溫(wen)(wen)(wen)液體(ti)(ti)膨脹,作(zuo)用(yong)(yong)力(li)克服了彈簧阻力(li),推動閥(fa)(fa)芯(xin)向下位(wei)移,閥(fa)(fa)門趨(qu)于關閉(bi)狀態,從(cong)(cong)而減少熱(re)媒(mei)介質(zhi)(zhi)(zhi)的流量;反之當(dang)介質(zhi)(zhi)(zhi)溫(wen)(wen)(wen)度低于設(she)定溫(wen)(wen)(wen)度時,感溫(wen)(wen)(wen)液體(ti)(ti)收(shou)縮,復(fu)位(wei)彈簧推動閥(fa)(fa)芯(xin)開啟(qi)狀態,增加熱(re)媒(mei)介質(zhi)(zhi)(zhi)流量,使(shi)被控(kong)(kong)介質(zhi)(zhi)(zhi)溫(wen)(wen)(wen)度趨(qu)于升(sheng)高(gao).循環往復(fu),從(cong)(cong)而使(shi)被控(kong)(kong)介質(zhi)(zhi)(zhi)的溫(wen)(wen)(wen)度值始(shi)終保持在設(she)定溫(wen)(wen)(wen)度允許的范圍內(nei).
