EDRV-16動態平衡電動調節閥DN25~250概述

DN25~250是(shi)(shi)區別于傳統(tong)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)調(diao)節閥(fa)(fa)的(de)(de)(de)(de)新代(dai)產品，是(shi)(shi)動(dong)(dong)(dong)(dong)(dong)態(tai)(tai)平(ping)(ping)衡與(yu)電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)調(diao)節體(ti)化(hua)(hua)的(de)(de)(de)(de)產品。 如下圖(tu)所示，在系(xi)統(tong)負荷(he)波動(dong)(dong)(dong)(dong)(dong)較大的(de)(de)(de)(de)變(bian)(bian)流(liu)量(liang)系(xi)統(tong)中(zhong)，當系(xi)統(tong)壓(ya)(ya)(ya)(ya)(ya)力變(bian)(bian)化(hua)(hua)時(shi)(shi)，DN25~250二(er)端(duan)的(de)(de)(de)(de)壓(ya)(ya)(ya)(ya)(ya)差(cha)（P1-P3）也隨之變(bian)(bian)化(hua)(hua)： ⑴、當進口壓(ya)(ya)(ya)(ya)(ya)力P1升(sheng)高(gao)時(shi)(shi)，（P1-P2）增(zeng)大，這時(shi)(shi)電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)閥(fa)(fa)閥(fa)(fa)芯(xin)向(xiang)上(shang)(shang)運(yun)動(dong)(dong)(dong)(dong)(dong)，使(shi)P1、P2間開(kai)(kai)(kai)度減(jian)少，閥(fa)(fa)芯(xin)壓(ya)(ya)(ya)(ya)(ya)力P2降低；當進口壓(ya)(ya)(ya)(ya)(ya)力P1降低時(shi)(shi)，（P1-P2）減(jian)小，這時(shi)(shi)電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)閥(fa)(fa)閥(fa)(fa)芯(xin)向(xiang)下運(yun)動(dong)(dong)(dong)(dong)(dong)，使(shi)P1、P2間開(kai)(kai)(kai)度增(zeng)大，閥(fa)(fa)芯(xin)壓(ya)(ya)(ya)(ya)(ya)力P2升(sheng)高(gao)。因(yin)此(ci)(ci)(ci)，無論系(xi)統(tong)的(de)(de)(de)(de)壓(ya)(ya)(ya)(ya)(ya)力怎樣變(bian)(bian)化(hua)(hua)，通過電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)閥(fa)(fa)閥(fa)(fa)芯(xin)的(de)(de)(de)(de)調(diao)節作用，P2、P3間的(de)(de)(de)(de)壓(ya)(ya)(ya)(ya)(ya)差(cha)始終(zhong)保持不(bu)變(bian)(bian)。因(yin)此(ci)(ci)(ci)這種動(dong)(dong)(dong)(dong)(dong)閥(fa)(fa)的(de)(de)(de)(de)抗干擾(rao)能力強，具有(you)(you)動(dong)(dong)(dong)(dong)(dong)態(tai)(tai)平(ping)(ping)衡的(de)(de)(de)(de)功(gong)能； ⑵、當直行(xing)(xing)程電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)執行(xing)(xing)器接受控(kong)制(zhi)(zhi)信號使(shi)閥(fa)(fa)軸延(yan)A—B向(xiang)上(shang)(shang)下運(yun)動(dong)(dong)(dong)(dong)(dong)（或角行(xing)(xing)程電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)執行(xing)(xing)器接受控(kong)制(zhi)(zhi)信號使(shi)閥(fa)(fa)軸延(yan)R向(xiang)旋(xuan)轉）時(shi)(shi)，P2、P3間的(de)(de)(de)(de)開(kai)(kai)(kai)度也隨之變(bian)(bian)化(hua)(hua)。由于不(bu)管(guan)系(xi)統(tong)壓(ya)(ya)(ya)(ya)(ya)差(cha)（P1-P3）如何變(bian)(bian)化(hua)(hua)，P2、P3間的(de)(de)(de)(de)壓(ya)(ya)(ya)(ya)(ya)差(cha)（P2-P3）始終(zhong)不(bu)變(bian)(bian)，因(yin)此(ci)(ci)(ci)對(dui)應于任開(kai)(kai)(kai)度位置，其(qi)輸送的(de)(de)(de)(de)水流(liu)量(liang)都是(shi)(shi)定(ding)的(de)(de)(de)(de)，并且電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)調(diao)節閥(fa)(fa)實際的(de)(de)(de)(de)流(liu)量(liang)特(te)性(xing)曲(qu)線(xian)與(yu)其(qi)理想的(de)(de)(de)(de)流(liu)量(liang)特(te)性(xing)曲(qu)線(xian)是(shi)(shi)致的(de)(de)(de)(de)，沒有(you)(you)偏(pian)離。因(yin)此(ci)(ci)(ci)這種電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)調(diao)節閥(fa)(fa)較傳統(tong)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)調(diao)節閥(fa)(fa)具有(you)(you)更好的(de)(de)(de)(de)調(diao)節特(te)性(xing)。
