產品介紹
SMC緩慢(man)啟(qi)動電磁閥(fa)時(shi)，必須按(an)設備(bei)每小時(shi)的(de)(de)(de)(de)耗汽量乘(cheng)以(yi)選(xuan)用倍率2-3倍為zui大(da)凝(ning)結水(shui)(shui)(shui)量，來(lai)選(xuan)擇低溫液(ye)態用途電磁閥(fa)的(de)(de)(de)(de)排(pai)(pai)水(shui)(shui)(shui)量。才(cai)能保證水(shui)(shui)(shui)力(li)控(kong)制閥(fa)在(zai)開車時(shi)能盡快排(pai)(pai)出凝(ning)結水(shui)(shui)(shui)，迅速提高(gao)加(jia)熱設備(bei)的(de)(de)(de)(de)溫度。電磁換向閥(fa)的(de)(de)(de)(de)品種繁多(duo)，按(an)其(qi)工作位(wei)(wei)(wei)置數和(he)通(tong)路數的(de)(de)(de)(de)多(duo)少(shao)可(ke)分為二(er)位(wei)(wei)(wei)三(san)(san)通(tong)、二(er)位(wei)(wei)(wei)四通(tong)、三(san)(san)位(wei)(wei)(wei)四通(tong)等；按(an)其(qi)復位(wei)(wei)(wei)和(he)定(ding)位(wei)(wei)(wei)形(xing)式可(ke)分為彈(dan)簧復位(wei)(wei)(wei)式、鋼(gang)球定(ding)位(wei)(wei)(wei)式、無(wu)復位(wei)(wei)(wei)彈(dan)簧式；按(an)其(qi)閥(fa)體與電磁鐵的(de)(de)(de)(de)連(lian)接形(xing)式可(ke)分為法蘭連(lian)接和(he)螺紋連(lian)接。水(shui)(shui)(shui)力(li)控(kong)制閥(fa)排(pai)(pai)放能量不(bu)夠，會造成凝(ning)結水(shui)(shui)(shui)不(bu)能及時(shi)排(pai)(pai)出，降低加(jia)熱設備(bei)的(de)(de)(de)(de)熱效率。

產品詳細說明
SMC緩慢(man)啟(qi)動電(dian)磁閥(fa)輸(shu)(shu)出(chu)壓(ya)(ya)(ya)力較(jiao)高或通徑(jing)較(jiao)大時，用(yong)(yong)調(diao)壓(ya)(ya)(ya)彈(dan)簧(huang)直(zhi)接(jie)調(diao)壓(ya)(ya)(ya)，則(ze)彈(dan)簧(huang)剛度必然過大，流量變化時，輸(shu)(shu)出(chu)壓(ya)(ya)(ya)力波(bo)動較(jiao)大，閥(fa)的(de)(de)(de)結構尺寸也將增大。為(wei)(wei)了(le)克服這些缺點，可采用(yong)(yong)先(xian)導(dao)式(shi)減(jian)(jian)壓(ya)(ya)(ya)閥(fa)。先(xian)導(dao)式(shi)減(jian)(jian)壓(ya)(ya)(ya)閥(fa)的(de)(de)(de)工作(zuo)(zuo)原理與(yu)直(zhi)動式(shi)的(de)(de)(de)基(ji)本(ben)相同。使用(yong)(yong)壽命電(dian)磁閥(fa)使用(yong)(yong)到主要零部(bu)件損壞，不(bu)能(neng)進行正常的(de)(de)(de)換向和復位動作(zuo)(zuo)，或者使用(yong)(yong)到其(qi)主要性(xing)能(neng)指標(biao)明顯(xian)惡化超過了(le)規定指標(biao)所經歷的(de)(de)(de)換向次數(shu)。先(xian)導(dao)式(shi)減(jian)(jian)壓(ya)(ya)(ya)閥(fa)所用(yong)(yong)的(de)(de)(de)調(diao)壓(ya)(ya)(ya)氣體，是由小型(xing)的(de)(de)(de)直(zhi)動式(shi)減(jian)(jian)壓(ya)(ya)(ya)閥(fa)供(gong)給的(de)(de)(de)。若(ruo)把小型(xing)直(zhi)動式(shi)減(jian)(jian)壓(ya)(ya)(ya)閥(fa)裝在(zai)(zai)閥(fa)體內部(bu)，則(ze)稱為(wei)(wei)內部(bu)先(xian)導(dao)式(shi)減(jian)(jian)壓(ya)(ya)(ya)閥(fa)；若(ruo)將小型(xing)直(zhi)動式(shi)減(jian)(jian)壓(ya)(ya)(ya)閥(fa)裝在(zai)(zai)主閥(fa)體外部(bu)，則(ze)稱為(wei)(wei)外部(bu)先(xian)導(dao)式(shi)減(jian)(jian)壓(ya)(ya)(ya)閥(fa)。
