日本SMC5通氣控閥相關知識
工作原理:
氣壓控制:靠氣壓力使閥芯切換以改變氣流方向的閥稱為氣壓控制換向閥,簡稱氣控閥。這種閥在易燃、易爆、潮濕、粉塵大、強磁場、高溫等惡劣工作環境中,以及不能使用電磁控制的環境中,工作安全可靠、壽命長。但氣壓控制閥的切換速度比電磁閥慢。氣壓控制可分成加壓控制、泄壓控制、壓差控制和延時控制。
按動(dong)作方式(shi)分(fen)(fen)類,可分(fen)(fen)為直動(dong)式(shi)和(he)導(dao)(dao)(dao)(dao)式(shi)。直接依靠電磁力(li)(li)(li)、氣壓(ya)(ya)力(li)(li)(li)、人力(li)(li)(li)和(he)機械力(li)(li)(li)使(shi)閥(fa)(fa)(fa)(fa)芯換(huan)(huan)(huan)向(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)的(de)(de)(de)閥(fa)(fa)(fa)(fa),稱(cheng)為直動(dong)式(shi)換(huan)(huan)(huan)向(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)閥(fa)(fa)(fa)(fa)。直動(dong)式(shi)閥(fa)(fa)(fa)(fa)的(de)(de)(de)通(tong)徑較小。導(dao)(dao)(dao)(dao)式(shi)氣閥(fa)(fa)(fa)(fa)由(you)導(dao)(dao)(dao)(dao)閥(fa)(fa)(fa)(fa)和(he)主(zhu)閥(fa)(fa)(fa)(fa)組成,依靠導(dao)(dao)(dao)(dao)閥(fa)(fa)(fa)(fa)輸(shu)出的(de)(de)(de)氣壓(ya)(ya)力(li)(li)(li),通(tong)過控(kong)制(zhi)(zhi)活塞等推動(dong)主(zhu)閥(fa)(fa)(fa)(fa)芯換(huan)(huan)(huan)向(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)的(de)(de)(de)那部(bu)分(fen)(fen)稱(cheng)為主(zhu)閥(fa)(fa)(fa)(fa)。通(tong)徑大(da)的(de)(de)(de)換(huan)(huan)(huan)向(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)閥(fa)(fa)(fa)(fa)大(da)都為導(dao)(dao)(dao)(dao)式(shi)換(huan)(huan)(huan)向(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)閥(fa)(fa)(fa)(fa)。導(dao)(dao)(dao)(dao)閥(fa)(fa)(fa)(fa)又分(fen)(fen)成內(nei)部(bu)導(dao)(dao)(dao)(dao)式(shi)和(he)外(wai)部(bu)導(dao)(dao)(dao)(dao)式(shi)。導(dao)(dao)(dao)(dao)控(kong)制(zhi)(zhi)的(de)(de)(de)氣源是(shi)主(zhu)閥(fa)(fa)(fa)(fa)提供(gong)的(de)(de)(de)為內(nei)部(bu)導(dao)(dao)(dao)(dao)式(shi);導(dao)(dao)(dao)(dao)控(kong)制(zhi)(zhi)的(de)(de)(de)氣源是(shi)外(wai)部(bu)供(gong)給的(de)(de)(de)為外(wai)部(bu)導(dao)(dao)(dao)(dao)式(shi)。外(wai)部(bu)導(dao)(dao)(dao)(dao)式(shi)換(huan)(huan)(huan)向(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)閥(fa)(fa)(fa)(fa)切換(huan)(huan)(huan)不受(shou)換(huan)(huan)(huan)向(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)閥(fa)(fa)(fa)(fa)使(shi)用壓(ya)(ya)力(li)(li)(li)大(da)小的(de)(de)(de)影響,故換(huan)(huan)(huan)向(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)閥(fa)(fa)(fa)(fa)可在低壓(ya)(ya)或真(zhen)空(kong)壓(ya)(ya)力(li)(li)(li)條(tiao)件下工作。
SMC各類產品, 除上述三(san)類控(kong)(kong)(kong)(kong)制(zhi)(zhi)閥外,還(huan)有能實(shi)(shi)現(xian)(xian)定邏輯功能的(de)(de)邏輯元(yuan)件(jian),包括元(yuan)件(jian)內部(bu)無可動(dong)部(bu)件(jian)的(de)(de)射流元(yuan)件(jian)和(he)(he)有可動(dong)部(bu)件(jian)的(de)(de)氣(qi)動(dong)邏輯元(yuan)件(jian)。在結構(gou)原理(li)上,邏輯元(yuan)件(jian)基本上和(he)(he)方(fang)向控(kong)(kong)(kong)(kong)制(zhi)(zhi)閥相同,僅僅是(shi)體積(ji)和(he)(he)通徑較小,般用來(lai)實(shi)(shi)現(xian)(xian)信(xin)號的(de)(de)邏輯運算功能。隨著氣(qi)動(dong)元(yuan)件(jian)的(de)(de)小型化(hua)以(yi)及(ji)PLC控(kong)(kong)(kong)(kong)制(zhi)(zhi)在氣(qi)動(dong)系統中的(de)(de)大(da)量(liang)(liang)應用,氣(qi)動(dong)邏輯元(yuan)件(jian)的(de)(de)應用范圍正在逐漸減小。從(cong)控(kong)(kong)(kong)(kong)制(zhi)(zhi)方(fang)式來(lai)分,氣(qi)動(dong)控(kong)(kong)(kong)(kong)制(zhi)(zhi)可分為(wei)斷續控(kong)(kong)(kong)(kong)制(zhi)(zhi)和(he)(he)連(lian)續控(kong)(kong)(kong)(kong)制(zhi)(zhi)兩類。在斷續控(kong)(kong)(kong)(kong)制(zhi)(zhi)系統中,通常要用壓力(li)控(kong)(kong)(kong)(kong)制(zhi)(zhi)閥、流量(liang)(liang)控(kong)(kong)(kong)(kong)制(zhi)(zhi)閥和(he)(he)方(fang)向控(kong)(kong)(kong)(kong)制(zhi)(zhi)閥來(lai)實(shi)(shi)現(xian)(xian)程序動(dong)作;連(lian)續控(kong)(kong)(kong)(kong)制(zhi)(zhi)系統中,除了要用壓力(li)、流量(liang)(liang)控(kong)(kong)(kong)(kong)制(zhi)(zhi)閥外,還(huan)要采用伺服、比例控(kong)(kong)(kong)(kong)制(zhi)(zhi)閥等,以(yi)便(bian)對(dui)系統進行連(lian)續控(kong)(kong)(kong)(kong)制(zhi)(zhi)。
