SMC3通氣控閥多種規格可選

特點一覽:

按動(dong)(dong)作方式(shi)(shi)(shi)分類(lei)，可(ke)(ke)分為(wei)(wei)直(zhi)動(dong)(dong)式(shi)(shi)(shi)和先(xian)(xian)(xian)(xian)導(dao)(dao)(dao)(dao)式(shi)(shi)(shi)。直(zhi)接(jie)依靠電磁(ci)力(li)(li)、氣壓(ya)力(li)(li)、人力(li)(li)和機械力(li)(li)使(shi)閥(fa)芯換(huan)(huan)向(xiang)的(de)閥(fa)，稱為(wei)(wei)直(zhi)動(dong)(dong)式(shi)(shi)(shi)換(huan)(huan)向(xiang)閥(fa)。直(zhi)動(dong)(dong)式(shi)(shi)(shi)閥(fa)的(de)通徑較(jiao)小。先(xian)(xian)(xian)(xian)導(dao)(dao)(dao)(dao)式(shi)(shi)(shi)氣閥(fa)由先(xian)(xian)(xian)(xian)導(dao)(dao)(dao)(dao)閥(fa)和主閥(fa)組成(cheng)，依靠先(xian)(xian)(xian)(xian)導(dao)(dao)(dao)(dao)閥(fa)輸出的(de)氣壓(ya)力(li)(li)，通過控(kong)制(zhi)活(huo)塞等推動(dong)(dong)主閥(fa)芯換(huan)(huan)向(xiang)的(de)那部(bu)分稱為(wei)(wei)主閥(fa)。通徑大(da)的(de)換(huan)(huan)向(xiang)閥(fa)大(da)都為(wei)(wei)先(xian)(xian)(xian)(xian)導(dao)(dao)(dao)(dao)式(shi)(shi)(shi)換(huan)(huan)向(xiang)閥(fa)。先(xian)(xian)(xian)(xian)導(dao)(dao)(dao)(dao)閥(fa)又分成(cheng)內部(bu)先(xian)(xian)(xian)(xian)導(dao)(dao)(dao)(dao)式(shi)(shi)(shi)和外(wai)(wai)部(bu)先(xian)(xian)(xian)(xian)導(dao)(dao)(dao)(dao)式(shi)(shi)(shi)。先(xian)(xian)(xian)(xian)導(dao)(dao)(dao)(dao)控(kong)制(zhi)的(de)氣源(yuan)是主閥(fa)提(ti)供的(de)為(wei)(wei)內部(bu)先(xian)(xian)(xian)(xian)導(dao)(dao)(dao)(dao)式(shi)(shi)(shi)；先(xian)(xian)(xian)(xian)導(dao)(dao)(dao)(dao)控(kong)制(zhi)的(de)氣源(yuan)是外(wai)(wai)部(bu)供給的(de)為(wei)(wei)外(wai)(wai)部(bu)先(xian)(xian)(xian)(xian)導(dao)(dao)(dao)(dao)式(shi)(shi)(shi)。外(wai)(wai)部(bu)先(xian)(xian)(xian)(xian)導(dao)(dao)(dao)(dao)式(shi)(shi)(shi)換(huan)(huan)向(xiang)閥(fa)切換(huan)(huan)不(bu)受換(huan)(huan)向(xiang)閥(fa)使(shi)用壓(ya)力(li)(li)大(da)小的(de)影響(xiang)，故換(huan)(huan)向(xiang)閥(fa)可(ke)(ke)在低(di)壓(ya)或真空壓(ya)力(li)(li)條件(jian)下工作。

氣控5通(tong)閥SYA系列(lie)(lie)與以前的5通(tong)電磁閥SY系列(lie)(lie)相(xiang)同閥體。

*體積小、流量大。

*重量輕（SYA 3120-M5:35g)。

*可與SY系(xi)列電磁閥安裝在同(tong)一集裝板上。

*采用底(di)板配管方式，可選擇(ze)及(ji)互換(huan)(huan)螺紋接(jie)(jie)管或快換(huan)(huan)接(jie)(jie)頭接(jie)(jie)管。

*標準型帶有手動鈕。

可分為彈(dan)性密(mi)(mi)封(feng)和間隙(xi)密(mi)(mi)封(feng)。彈(dan)性密(mi)(mi)封(feng)基(ji)本無(wu)泄漏，但受(shou)溫度影響；間隙(xi)密(mi)(mi)封(feng)雖存(cun)在微露但溫度使用范圍較(jiao)寬，頻率高。

閥(fa)的連接(jie)方式有管(guan)式連接(jie)、板式連接(jie)、法(fa)蘭連接(jie)和(he)集(ji)裝式連接(jie)。

按(an)流通能力的(de)(de)(de)分(fen)類(lei)有兩種：一(yi)是按(an)連(lian)(lian)接(jie)口徑分(fen)類(lei)，另一(yi)種是按(an)有效(xiao)截面(mian)積分(fen)類(lei)。連(lian)(lian)接(jie)口徑有用閥的(de)(de)(de)公(gong)稱通徑表(biao)示的(de)(de)(de)，有用連(lian)(lian)接(jie)口徑的(de)(de)(de)連(lian)(lian)接(jie)螺(luo)紋表(biao)示的(de)(de)(de)。
