MAC氣控閥原裝產品價格好
MAC氣控閥(fa)是指在氣動系(xi)統中控制氣流的壓力、流量和流動方向(xiang)，并保證氣動執行元件或(huo)機構正常工作的各類(lei)氣動元件。
控制和(he)調節壓縮空(kong)氣壓力的元件稱為壓力控制閥。
控(kong)制(zhi)和調(diao)節壓縮空氣流量(liang)(liang)的元件稱為(wei)流量(liang)(liang)控(kong)制(zhi)閥。
改變和控(kong)(kong)制(zhi)氣流(liu)流(liu)動方(fang)向(xiang)的元(yuan)件稱為方(fang)向(xiang)控(kong)(kong)制(zhi)閥。
除上述三類控制閥(fa)外(wai)，還有能實(shi)現一定邏輯功(gong)能的(de)邏輯元件，包括元件內部(bu)無可(ke)動(dong)部(bu)件的(de)射流(liu)元件和有可(ke)動(dong)部(bu)件的(de)氣動(dong)邏輯元件。
在(zai)(zai)(zai)結構(gou)原(yuan)理上，邏輯(ji)元(yuan)件基本上和(he)方(fang)向控(kong)制(zhi)閥相同，僅僅是體積和(he)通(tong)徑較(jiao)小(xiao)，一(yi)般用來實現信號的邏輯(ji)運算(suan)功能(neng)。近年(nian)來，隨著氣動元(yuan)件的小(xiao)型(xing)化(hua)以及PLC控(kong)制(zhi)在(zai)(zai)(zai)氣動系統中(zhong)的大量應(ying)用，氣動邏輯(ji)元(yuan)件的應(ying)用范圍正(zheng)在(zai)(zai)(zai)逐漸減小(xiao)。
從(cong)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)方式來分，氣動控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)可分為斷續(xu)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)和連續(xu)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)兩類。在斷續(xu)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)系(xi)統中，通(tong)常要用壓(ya)力控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)閥(fa)、流(liu)量(liang)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)閥(fa)和方向控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)閥(fa)來實現(xian)程序動作;連續(xu)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)系(xi)統中，除(chu)了(le)要用壓(ya)力、流(liu)量(liang)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)閥(fa)外，還要采(cai)用伺服、比例控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)閥(fa)等，以便對系(xi)統進行連續(xu)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)。
MAC氣控閥的工作原理
1、氣控閥工作時管外(wai)(wai),缸筒(tong)的內徑大小(xiao)代表了(le)氣缸輸出(chu)力(li)的大小(xiao)常使(shi)用鋁合(he)金(jin)壓鑄,桿(gan)(gan)側端蓋(gai)上設密封圈和防塵圈,微(wei)型缸有使(shi)用黃銅(tong)材料的,以防止(zhi)從(cong)活塞桿(gan)(gan)處向(xiang)外(wai)(wai)漏。
2、氣(qi)和防止(zhi)外部(bu)灰(hui)塵混入缸內,現在為(wei)減輕重(zhong)量并防銹,桿側端(duan)蓋上設(she)有導向套(tao)(tao),導向套(tao)(tao)通常使用燒(shao)含油(you)合金(jin)的(de),氣(qi)動氣(qi)控閥(fa)的(de)工作時為(wei)了減小活塞(sai)桿伸出(chu)時的(de)下(xia)彎量,延長。
3、氣(qi)控閥使用(yong)壽命,前傾銅鑄(zhu)件,承受(shou)活塞桿上(shang)少(shao)量(liang)的(de)橫(heng)向負載(zai),有(you)的(de)還在端(duan)蓋(gai)內設(she)有(you)緩沖機構,以(yi)提高氣(qi)缸的(de)導向精(jing)度,端(duan)蓋(gai)過(guo)去常用(yong)可(ke)鍛鑄(zhu)鐵,端(duan)蓋(gai)上(shang)設(she)有(you)進排(pai)氣(qi)通口。
