產品介紹
SMC緩慢啟動電磁閥輸出壓(ya)力(li)(li)較(jiao)高或通徑較(jiao)大(da)時(shi)，用(yong)調壓(ya)彈簧(huang)直(zhi)接調壓(ya)，則彈簧(huang)剛度必然過大(da)，流量變(bian)化時(shi)，輸出壓(ya)力(li)(li)波動較(jiao)大(da)，閥的結構尺寸也(ye)將(jiang)增大(da)。為了克(ke)服這些缺點(dian)，可采用(yong)先導(dao)式減壓(ya)閥。

產品詳細說明
SMC緩慢啟動電(dian)磁閥(fa)(fa)時(shi)，必(bi)須按(an)設備(bei)每小(xiao)時(shi)的(de)耗汽(qi)量(liang)乘以選(xuan)用(yong)倍率2-3倍為zui大(da)凝結(jie)水(shui)量(liang)，來選(xuan)擇低溫(wen)液態用(yong)途電(dian)磁閥(fa)(fa)的(de)排水(shui)量(liang)。才能保證水(shui)力控制閥(fa)(fa)在開車時(shi)能盡快排出(chu)凝結(jie)水(shui)，迅速提(ti)高加(jia)熱設備(bei)的(de)溫(wen)度(du)。電(dian)磁換向閥(fa)(fa)的(de)品種繁多(duo)，按(an)其(qi)工作位(wei)(wei)(wei)(wei)置數(shu)和(he)(he)通(tong)路數(shu)的(de)多(duo)少可(ke)分(fen)(fen)為二位(wei)(wei)(wei)(wei)三通(tong)、二位(wei)(wei)(wei)(wei)四(si)通(tong)、三位(wei)(wei)(wei)(wei)四(si)通(tong)等；按(an)其(qi)復位(wei)(wei)(wei)(wei)和(he)(he)定位(wei)(wei)(wei)(wei)形(xing)式(shi)(shi)可(ke)分(fen)(fen)為彈(dan)簧復位(wei)(wei)(wei)(wei)式(shi)(shi)、鋼球定位(wei)(wei)(wei)(wei)式(shi)(shi)、無復位(wei)(wei)(wei)(wei)彈(dan)簧式(shi)(shi)；按(an)其(qi)閥(fa)(fa)體與電(dian)磁鐵的(de)連(lian)接(jie)形(xing)式(shi)(shi)可(ke)分(fen)(fen)為法蘭連(lian)接(jie)和(he)(he)螺紋(wen)連(lian)接(jie)。

產品特點
SMC緩慢啟動(dong)(dong)(dong)電磁(ci)閥(fa)(fa)(fa)(fa)輸(shu)出(chu)壓(ya)(ya)(ya)(ya)力較(jiao)高或通徑(jing)較(jiao)大(da)時，用(yong)調壓(ya)(ya)(ya)(ya)彈簧直(zhi)(zhi)接調壓(ya)(ya)(ya)(ya)，則彈簧剛(gang)度必然過大(da)，流量變(bian)化時，輸(shu)出(chu)壓(ya)(ya)(ya)(ya)力波動(dong)(dong)(dong)較(jiao)大(da)，閥(fa)(fa)(fa)(fa)的(de)(de)(de)結構尺寸也(ye)將增大(da)。為了(le)(le)克服這些(xie)缺點，可采用(yong)先導(dao)式(shi)(shi)減(jian)壓(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)(fa)。先導(dao)式(shi)(shi)減(jian)壓(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)(fa)的(de)(de)(de)工(gong)作原理與直(zhi)(zhi)動(dong)(dong)(dong)式(shi)(shi)的(de)(de)(de)基本相同。使(shi)用(yong)壽命(ming)電磁(ci)閥(fa)(fa)(fa)(fa)使(shi)用(yong)到(dao)主(zhu)要(yao)零部件損(sun)壞，不能進(jin)行正常的(de)(de)(de)換(huan)(huan)向和(he)復(fu)位(wei)動(dong)(dong)(dong)作，或者使(shi)用(yong)到(dao)其(qi)主(zhu)要(yao)性能指標明顯惡化超過了(le)(le)規定指標所經歷的(de)(de)(de)換(huan)(huan)向次數。先導(dao)式(shi)(shi)減(jian)壓(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)(fa)所用(yong)的(de)(de)(de)調壓(ya)(ya)(ya)(ya)氣(qi)體，是由小型的(de)(de)(de)直(zhi)(zhi)動(dong)(dong)(dong)式(shi)(shi)減(jian)壓(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)(fa)供給的(de)(de)(de)。若把小型直(zhi)(zhi)動(dong)(dong)(dong)式(shi)(shi)減(jian)壓(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)(fa)裝(zhuang)在閥(fa)(fa)(fa)(fa)體內部，則稱為內部先導(dao)式(shi)(shi)減(jian)壓(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)(fa)；若將小型直(zhi)(zhi)動(dong)(dong)(dong)式(shi)(shi)減(jian)壓(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)(fa)裝(zhuang)在主(zhu)閥(fa)(fa)(fa)(fa)體外部，則稱為外部先導(dao)式(shi)(shi)減(jian)壓(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)(fa)。與直(zhi)(zhi)動(dong)(dong)(dong)式(shi)(shi)減(jian)壓(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)(fa)相比，該閥(fa)(fa)(fa)(fa)增加了(le)(le)由噴(pen)嘴4、擋(dang)板(ban)固定節(jie)(jie)流孔(kong)9及(ji)氣(qi)室B所組(zu)成的(de)(de)(de)噴(pen)嘴擋(dang)板(ban)放大(da)環節(jie)(jie)。
