自(zi)力(li)(li)式(shi)壓(ya)力(li)(li)調節(jie)閥(fa)在(zai)工業上(shang)廣泛應用，是(shi)(shi)一(yi)種(zhong)無需外來(lai)資源(yuan)，只需要被測自(zi)身壓(ya)力(li)(li)、溫度或者流量(liang)的(de)(de)變化，設定(ding)預先的(de)(de)值(zhi)就能自(zi)動調節(jie)的(de)(de)一(yi)種(zhong)控制(zhi)(zhi)裝(zhuang)置，這是(shi)(shi)一(yi)種(zhong)節(jie)能型的(de)(de)儀表，具有(you)(you)控制(zhi)(zhi)執行等多功能的(de)(de)儀表控制(zhi)(zhi)系統。它的(de)(de)種(zhong)類可分(fen)為自(zi)力(li)(li)式(shi)壓(ya)力(li)(li)（微壓(ya)）調節(jie)閥(fa)、自(zi)力(li)(li)式(shi)（壓(ya)差）流量(liang)調節(jie)閥(fa)、自(zi)力(li)(li)式(shi)溫度調節(jie)閥(fa)。適(shi)用于(yu)城市供(gong)(gong)熱、供(gong)(gong)曖及(ji)沒(mei)有(you)(you)供(gong)(gong)電、供(gong)(gong)氣又需控制(zhi)(zhi)的(de)(de)場(chang)合。

我(wo)們(men)(men)(men)只(zhi)需要根據需要去了解我(wo)們(men)(men)(men)分支行業所需要的閥(fa)(fa)就好了。液(ye)(ye)壓(ya)技術發(fa)(fa)展(zhan)到(dao)今天(tian)，國(guo)(guo)內(nei)的液(ye)(ye)壓(ya)廠家也越來(lai)(lai)越多(duo)(duo)，但是(shi)(shi)相比國(guo)(guo)外來(lai)(lai)講(jiang)，國(guo)(guo)內(nei)的液(ye)(ye)壓(ya)技術發(fa)(fa)展(zhan)年(nian)限短。但是(shi)(shi)我(wo)們(men)(men)(men)雖然發(fa)(fa)展(zhan)年(nian)限短，單電(dian)控板(ban)式閥(fa)(fa)生產商，但是(shi)(shi)我(wo)們(men)(men)(men)可以說是(shi)(shi)“站在(zai)巨人的肩上(shang)(shang)”去發(fa)(fa)展(zhan)的，有很多(duo)(duo)國(guo)(guo)外的閥(fa)(fa)供我(wo)們(men)(men)(men)學習和研究以及(ji)使用。板(ban)式閥(fa)(fa)連接管道的油口不是(shi)(shi)直接做(zuo)(zuo)在(zai)閥(fa)(fa)上(shang)(shang)，而是(shi)(shi)做(zuo)(zuo)在(zai)底板(ban)上(shang)(shang)，閥(fa)(fa)通過螺栓被固定在(zai)底板(ban)上(shang)(shang)。

兩(liang)(liang)位三通(tong)(tong)電(dian)(dian)磁閥(fa)分(fen)為常(chang)閉型(xing)和常(chang)開型(xing)兩(liang)(liang)種(zhong)，常(chang)閉型(xing)指線(xian)(xian)(xian)(xian)(xian)圈沒通(tong)(tong)電(dian)(dian)時(shi)氣(qi)路(lu)是(shi)(shi)斷的，常(chang)開型(xing)指線(xian)(xian)(xian)(xian)(xian)圈沒通(tong)(tong)電(dian)(dian)時(shi)氣(qi)路(lu)是(shi)(shi)通(tong)(tong)的。常(chang)閉型(xing)兩(liang)(liang)位三通(tong)(tong)電(dian)(dian)磁閥(fa)動作原理：給線(xian)(xian)(xian)(xian)(xian)圈通(tong)(tong)電(dian)(dian)，氣(qi)路(lu)接通(tong)(tong)，線(xian)(xian)(xian)(xian)(xian)圈一旦斷電(dian)(dian)，單電(dian)(dian)控(kong)板(ban)(ban)式閥(fa)咨詢，氣(qi)路(lu)就會(hui)斷開，這相當于“點(dian)動”。常(chang)開型(xing)兩(liang)(liang)位三通(tong)(tong)單電(dian)(dian)控(kong)電(dian)(dian)磁閥(fa)動作原理：給線(xian)(xian)(xian)(xian)(xian)圈通(tong)(tong)電(dian)(dian)，馬鞍山單電(dian)(dian)控(kong)板(ban)(ban)式閥(fa)，氣(qi)路(lu)斷開，單電(dian)(dian)控(kong)板(ban)(ban)式閥(fa)報(bao)價，線(xian)(xian)(xian)(xian)(xian)圈一旦斷電(dian)(dian)，氣(qi)路(lu)就會(hui)接通(tong)(tong)，這也是(shi)(shi)“點(dian)動”。
