AC220V兩位三通CKD電磁閥是否需要裝消聲器？

兩(liang)位五通(tong)CKD電(dian)磁(ci)(ci)閥通(tong)電(dian)時(shi)，電(dian)磁(ci)(ci)力(li)(li)驅動(dong)先(xian)(xian)導(dao)閥打開先(xian)(xian)導(dao)閥，主(zhu)閥上腔(qiang)壓力(li)(li)迅速(su)下(xia)(xia)降(jiang)，在(zai)(zai)主(zhu)閥上下(xia)(xia)腔(qiang)內形(xing)成(cheng)壓差，依靠(kao)介質壓力(li)(li)推(tui)動(dong)主(zhu)閥關(guan)閉件上移，閥門(men)開啟；斷電(dian)時(shi)，彈簧力(li)(li)把先(xian)(xian)導(dao)閥關(guan)閉，入口介質壓力(li)(li)通(tong)過先(xian)(xian)導(dao)孔迅速(su)進入主(zhu)閥上腔(qiang)在(zai)(zai)上腔(qiang)內形(xing)成(cheng)壓差，從而使(shi)主(zhu)閥關(guan)閉。

特(te)點：體積(ji)小，功率低，但介質(zhi)壓差(cha)范圍受(shou)限，必須滿(man)足壓差(cha)條件。

兩位(wei)三(san)(san)(san)通(tong)(tong)(tong)CKD電磁(ci)閥通(tong)(tong)(tong)常與單作(zuo)用(yong)氣(qi)(qi)動執行機構(gou)配套使用(yong)，兩位(wei)是(shi)兩個(ge)(ge)(ge)位(wei)置可控：開(kai)-關，三(san)(san)(san)通(tong)(tong)(tong)是(shi)有(you)三(san)(san)(san)個(ge)(ge)(ge)通(tong)(tong)(tong)道通(tong)(tong)(tong)氣(qi)(qi)，一般情況下1個(ge)(ge)(ge)通(tong)(tong)(tong)道與氣(qi)(qi)源連接，另外兩個(ge)(ge)(ge)通(tong)(tong)(tong)道1個(ge)(ge)(ge)與執行機構(gou)的進氣(qi)(qi)口連接，1個(ge)(ge)(ge)與執行機構(gou)排氣(qi)(qi)口連接，具(ju)體的工(gong)作(zuo)原(yuan)(yuan)理可以參照單作(zuo)用(yong)氣(qi)(qi)動執行機構(gou)的工(gong)作(zuo)原(yuan)(yuan)理圖。

兩(liang)位(wei)五通(tong)(tong)(tong)CKD電磁閥通(tong)(tong)(tong)常(chang)與雙作(zuo)用(yong)氣動執行(xing)(xing)機(ji)構(gou)配套使用(yong)，兩(liang)位(wei)是(shi)兩(liang)個位(wei)置可控：開-關(guan)，五通(tong)(tong)(tong)是(shi)有五個通(tong)(tong)(tong)道通(tong)(tong)(tong)氣，其中1個與氣源連接，兩(liang)個與雙作(zuo)用(yong)氣缸的外部(bu)氣室的進出(chu)氣口(kou)(kou)連接，兩(liang)個與內部(bu)氣室的進出(chu)氣口(kou)(kou)接連，具(ju)體的工作(zuo)原(yuan)理可參(can)照雙作(zuo)用(yong)氣動執行(xing)(xing)機(ji)構(gou)工作(zuo)原(yuan)理

在氣路(或液路)上來說，兩(liang)位三通(tong)CKD電磁(ci)閥(fa)具有1個進氣孔(接進氣氣源)、1個出(chu)氣孔(提供給目標設備氣源)、1個排(pai)氣孔(一般安裝(zhuang)一個消聲(sheng)器(qi)，如果(guo)不怕噪(zao)音(yin)的話也可以不裝(zhuang)@_@)。

兩(liang)位五通CKD電磁閥(fa)具有1個(ge)(ge)進氣(qi)(qi)(qi)孔(kong)(接進氣(qi)(qi)(qi)氣(qi)(qi)(qi)源)、1個(ge)(ge)正(zheng)動作(zuo)(zuo)(zuo)(zuo)出(chu)氣(qi)(qi)(qi)孔(kong)和1個(ge)(ge)反動作(zuo)(zuo)(zuo)(zuo)出(chu)氣(qi)(qi)(qi)孔(kong)(分別提(ti)供給目標設(she)備的(de)一(yi)正(zheng)一(yi)反動作(zuo)(zuo)(zuo)(zuo)的(de)氣(qi)(qi)(qi)源)、1個(ge)(ge)正(zheng)動作(zuo)(zuo)(zuo)(zuo)排(pai)氣(qi)(qi)(qi)孔(kong)和1個(ge)(ge)反動作(zuo)(zuo)(zuo)(zuo)排(pai)氣(qi)(qi)(qi)孔(kong)(安裝(zhuang)消聲器)。

對(dui)于小型自動(dong)控制設備(bei)，氣(qi)管(guan)一(yi)般(ban)選(xuan)用8~12mm的工業膠(jiao)氣(qi)管(guan)。在(zai)電(dian)(dian)(dian)氣(qi)上來說，兩(liang)位三(san)通CKD電(dian)(dian)(dian)磁閥一(yi)般(ban)為(wei)單(dan)電(dian)(dian)(dian)控(即(ji)單(dan)線(xian)(xian)圈)，兩(liang)位五通CKD電(dian)(dian)(dian)磁閥一(yi)般(ban)為(wei)雙電(dian)(dian)(dian)控(即(ji)雙線(xian)(xian)圈)。線(xian)(xian)圈電(dian)(dian)(dian)壓等級一(yi)般(ban)采(cai)用DC24V、AC220V等。

兩(liang)位(wei)三(san)通(tong)(tong)CKD電磁閥分為常(chang)閉型(xing)和常(chang)開型(xing)兩(liang)種，常(chang)閉型(xing)指線圈(quan)沒(mei)通(tong)(tong)電時(shi)氣路(lu)是(shi)斷(duan)的，常(chang)開型(xing)指線圈(quan)沒(mei)通(tong)(tong)電時(shi)氣路(lu)是(shi)通(tong)(tong)的。

常閉型兩位三(san)通(tong)CKD電(dian)磁閥(fa)動(dong)作(zuo)原(yuan)理：給(gei)線圈(quan)通(tong)電(dian)，氣(qi)路接通(tong)，線圈(quan)一(yi)旦斷(duan)(duan)電(dian)，氣(qi)路就會斷(duan)(duan)開，這相當于“點動(dong)”。

常開型兩位三(san)通單(dan)電(dian)控CKD電(dian)磁閥動作原理：給線圈通電(dian)，氣(qi)路斷開，線圈一旦斷電(dian)，氣(qi)路就會接通，這也是“點動”。

兩位五通(tong)雙電(dian)控CKD電(dian)磁閥動(dong)作(zuo)(zuo)原理：給正(zheng)(zheng)動(dong)作(zuo)(zuo)線(xian)圈(quan)通(tong)電(dian)，則正(zheng)(zheng)動(dong)作(zuo)(zuo)氣(qi)(qi)(qi)路接(jie)通(tong)(正(zheng)(zheng)動(dong)作(zuo)(zuo)出氣(qi)(qi)(qi)孔(kong)有氣(qi)(qi)(qi))，即使給正(zheng)(zheng)動(dong)作(zuo)(zuo)線(xian)圈(quan)斷電(dian)后正(zheng)(zheng)動(dong)作(zuo)(zuo)氣(qi)(qi)(qi)路仍然是接(jie)通(tong)的，將(jiang)會(hui)一(yi)直維(wei)持到給反動(dong)作(zuo)(zuo)線(xian)圈(quan)通(tong)電(dian)為止(zhi)。
