埃美柯閥門自力式壓差控制閥概述：

自(zi)(zi)力式壓(ya)差控制閥ZYC是一種自(zi)(zi)動恒定(ding)壓(ya)差的(de)(de)水(shui)力工(gong)況(kuang)平(ping)衡用(yong)閥，應用(yong)于集中拱熱、中央空調等(deng)水(shui)系(xi)統(tong)中，有利于被控系(xi)統(tong)各用(yong)戶(hu)和末端裝(zhuang)置的(de)(de)自(zi)(zi)主調節，尤(you)其適(shi)用(yong)于分戶(hu)計量供暖系(xi)統(tong)和變流量空調系(xi)統(tong)。

埃美柯自(zi)力式壓差(cha)控制(zhi)閥結構特點:

本體是由(you)(you)能(neng)改變流通(tong)(tong)阻力(li)的(de)(de)雙(shuang)通(tong)(tong)道自動(dong)調(diao)節(jie)閥和(he)由(you)(you)膜片分隔而成兩個獨立小室的(de)(de)控(kong)制器(qi)組(zu)合而成，一側小室與回水(shui)(shui)管(guan)道相(xiang)通(tong)(tong)。使用(yong)(yong)時安裝在回水(shui)(shui)管(guan)道上。通(tong)(tong)道自動(dong)調(diao)節(jie)閥是執行(xing)器(qi)，其(qi)動(dong)作的(de)(de)動(dong)力(li)來(lai)源于供(gong)水(shui)(shui)壓(ya)(ya)力(li)P1與回水(shui)(shui)壓(ya)(ya)力(li)P2之間(jian)的(de)(de)壓(ya)(ya)力(li)差變化。控(kong)制器(qi)是一個壓(ya)(ya)差比較(jiao)器(qi)，其(qi)壓(ya)(ya)差值是按被控(kong)采暖(nuan)系(xi)統(tong)的(de)(de)阻力(li)選用(yong)(yong)，回水(shui)(shui)側內(nei)的(de)(de)彈簧反力(li)用(yong)(yong)來(lai)平衡(heng)供(gong)水(shui)(shui)與水(shui)(shui)間(jian)的(de)(de)壓(ya)(ya)力(li)差。當被控(kong)采暖(nuan)系(xi)統(tong)的(de)(de)一些(xie)用(yong)(yong)戶(hu)進行(xing)室溫(wen)調(diao)節(jie)，阻力(li)增加或減少時，會引起循環流量(liang)變化，直(zhi)至膜片兩側的(de)(de)壓(ya)(ya)力(li)平衡(heng)為止(zhi)，使被控(kong)系(xi)統(tong)內(nei)部自動(dong)調(diao)節(jie)。

自力(li)(li)式壓(ya)(ya)差(cha)(cha)(cha)控(kong)(kong)制閥(fa)的本體是(shi)(shi)由(you)(you)能改變流通阻(zu)力(li)(li)的雙通道(dao)自動(dong)(dong)(dong)調節閥(fa)和由(you)(you)膜片(pian)分隔(ge)而成兩個獨立小室的控(kong)(kong)制器(qi)組合而成，一側(ce)(ce)小室與(yu)回(hui)(hui)水(shui)(shui)管(guan)道(dao)相通。使(shi)用時(shi)安(an)裝在回(hui)(hui)水(shui)(shui)管(guan)道(dao)上(shang)。通道(dao)自動(dong)(dong)(dong)調節閥(fa)是(shi)(shi)執行(xing)器(qi)，其(qi)動(dong)(dong)(dong)作的動(dong)(dong)(dong)力(li)(li)來(lai)源于供水(shui)(shui)壓(ya)(ya)力(li)(li)P1與(yu)回(hui)(hui)水(shui)(shui)壓(ya)(ya)力(li)(li)P2之間的壓(ya)(ya)力(li)(li)差(cha)(cha)(cha)變化。控(kong)(kong)制器(qi)是(shi)(shi)一個壓(ya)(ya)差(cha)(cha)(cha)比較器(qi)，其(qi)壓(ya)(ya)差(cha)(cha)(cha)值是(shi)(shi)按被控(kong)(kong)采(cai)暖系(xi)(xi)統的阻(zu)力(li)(li)選(xuan)用，回(hui)(hui)水(shui)(shui)側(ce)(ce)內的彈簧反力(li)(li)用來(lai)平(ping)衡供水(shui)(shui)與(yu)水(shui)(shui)間的壓(ya)(ya)力(li)(li)差(cha)(cha)(cha)。當被控(kong)(kong)采(cai)暖系(xi)(xi)統的一些用戶進行(xing)室溫調節，阻(zu)力(li)(li)增加或減(jian)少時(shi)，會引起循環流量變化，直至膜片(pian)兩側(ce)(ce)的壓(ya)(ya)力(li)(li)平(ping)衡為止，使(shi)被控(kong)(kong)系(xi)(xi)統內部自動(dong)(dong)(dong)調節。
