電動調(diao)節(jie)閥(fa)(fa)(fa)與風機(ji)連鎖，以(yi)保證(zheng)切斷風機(ji)電源(yuan)時風閥(fa)(fa)(fa)亦同(tong)時關閉(bi)。電動調(diao)節(jie)閥(fa)(fa)(fa)亦可(ke)實現與風機(ji)的聯(lian)動，當風機(ji)切斷電源(yuan)時關閉(bi)電動調(diao)節(jie)閥(fa)(fa)(fa)。

新(xin)風(feng)換氣機溫(wen)度(du)(du)控(kong)(kong)(kong)制(zhi)系(xi)統由比例積分溫(wen)度(du)(du)控(kong)(kong)(kong)制(zhi)器、安裝在(zai)送風(feng)管內的(de)溫(wen)度(du)(du)傳(chuan)感(gan)器和電動(dong)調(diao)節閥組成。控(kong)(kong)(kong)制(zhi)器的(de)作用是把置(zhi)于送風(feng)風(feng)道(dao)的(de)溫(wen)度(du)(du)傳(chuan)感(gan)器所(suo)檢測到的(de)送風(feng)溫(wen)度(du)(du)傳(chuan)送至溫(wen)控(kong)(kong)(kong)器與控(kong)(kong)(kong)制(zhi)器設(she)定的(de)溫(wen)度(du)(du)進行(xing)比較，并根據PI運算的(de)結果，溫(wen)控(kong)(kong)(kong)器給電動(dong)調(diao)節閥一個開/關閥的(de)信號，從而(er)使送風(feng)溫(wen)度(du)(du)保持在(zai)所(suo)需要的(de)范(fan)圍(wei)。
