夾(jia)管(guan)(guan)閥(fa)(fa)(fa)（Pinch Valve），在國內又稱為管(guan)(guan)夾(jia)閥(fa)(fa)(fa)、壓(ya)管(guan)(guan)閥(fa)(fa)(fa)、氣囊閥(fa)(fa)(fa)、箍斷閥(fa)(fa)(fa)等。利(li)用(yong)氣動(dong)、電動(dong)、手(shou)動(dong)或者(zhe)液動(dong)等驅動(dong)方式(shi)擠壓(ya)套(tao)管(guan)(guan)，達到(dao)開(kai)關/調節的(de)作(zuo)用(yong)，電磁夾(jia)管(guan)(guan)閥(fa)(fa)(fa)是夾(jia)管(guan)(guan)閥(fa)(fa)(fa)的(de)一種形式(shi)。套(tao)管(guan)(guan)（軟(ruan)管(guan)(guan)）是夾(jia)管(guan)(guan)閥(fa)(fa)(fa)的(de)重(zhong)要零件(jian)，提供抗(kang)腐蝕、抗(kang)磨損和承(cheng)壓(ya)能力，另外電磁線(xian)圈(quan)、銜鐵、彈簧等內部零件(jian)的(de)優劣同(tong)樣影響著閥(fa)(fa)(fa)的(de)壽命(ming)。

工作原理

電(dian)(dian)動夾(jia)管(guan)閥(fa)(fa)(fa)(fa)采用(yong)電(dian)(dian)機驅(qu)動閥(fa)(fa)(fa)(fa)芯運動，夾(jia)管(guan)閥(fa)(fa)(fa)(fa)，從(cong)(cong)而擠(ji)壓或松開閥(fa)(fa)(fa)(fa)芯與檔條(tiao)之(zhi)間的(de)(de)軟(ruan)(ruan)管(guan)來控制(zhi)軟(ruan)(ruan)管(guan)內流(liu)體(ti)(ti)的(de)(de)通(tong)斷。流(liu)體(ti)(ti)介質僅從(cong)(cong)軟(ruan)(ruan)管(guan)中通(tong)過(guo)，避免與閥(fa)(fa)(fa)(fa)體(ti)(ti)的(de)(de)其他(ta)部件(jian)接(jie)觸導致污染。相對于(yu)傳統的(de)(de)電(dian)(dian)磁(ci)夾(jia)管(guan)閥(fa)(fa)(fa)(fa)，電(dian)(dian)動夾(jia)管(guan)閥(fa)(fa)(fa)(fa)擁(yong)有更好地節能效果(guo)、更低的(de)(de)電(dian)(dian)磁(ci)干擾以及(ji)更強的(de)(de)耐壓能力。以常(chang)開式兩線制(zhi)夾(jia)管(guan)閥(fa)(fa)(fa)(fa)為例，在未(wei)通(tong)電(dian)(dian)的(de)(de)情況下，滑塊處(chu)于(yu)較靠近電(dian)(dian)動機的(de)(de)位(wei)置。滑塊和(he)閥(fa)(fa)(fa)(fa)頭的(de)(de)擋條(tiao)之(zhi)間的(de)(de)距離(li)較遠(yuan)，電(dian)(dian)動夾(jia)管(guan)閥(fa)(fa)(fa)(fa)批發，處(chu)于(yu)滑塊和(he)擋條(tiao)之(zhi)間的(de)(de)軟(ruan)(ruan)管(guan)則處(chu)于(yu)打(da)開的(de)(de)狀(zhuang)態。

當接(jie)通電(dian)(dian)(dian)源時，夾管閥內(nei)部的(de)電(dian)(dian)(dian)子(zi)(zi)電(dian)(dian)(dian)路接(jie)收到(dao)(dao)電(dian)(dian)(dian)源接(jie)通的(de)信號(hao)，驅動電(dian)(dian)(dian)動機(ji)旋轉(zhuan)(zhuan)。旋轉(zhuan)(zhuan)的(de)電(dian)(dian)(dian)動機(ji)通過螺(luo)桿等機(ji)械部件帶(dai)動滑塊向擋條方向運動，將軟管夾緊(jin)后，內(nei)部電(dian)(dian)(dian)子(zi)(zi)電(dian)(dian)(dian)路感應到(dao)(dao)到(dao)(dao)位信息，控制電(dian)(dian)(dian)機(ji)停止轉(zhuan)(zhuan)動，夾管閥保持夾緊(jin)狀態(tai)。

當斷(duan)(duan)開(kai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)時(shi)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)被(bei)切斷(duan)(duan)的(de)(de)信(xin)號(hao)首先會被(bei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)所感知。這(zhe)個時(shi)候(hou)雖然外部(bu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)被(bei)切斷(duan)(duan)，但是由(you)于內部(bu)有電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容的(de)(de)存(cun)(cun)在(zai)，具有一定的(de)(de)能(neng)(neng)源(yuan)(yuan)儲存(cun)(cun)，仍然能(neng)(neng)夠繼續為電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。當電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)感受(shou)到電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)被(bei)切斷(duan)(duan)的(de)(de)信(xin)號(hao)以后(hou)，會發出指令(ling)，比例夾(jia)管閥批(pi)發價，通(tong)過驅動(dong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)來驅動(dong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)反向轉動(dong)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)的(de)(de)軸會帶動(dong)滑塊向電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)夾(jia)管閥打(da)開(kai)的(de)(de)方向運動(dong)。當軟管已經進入(ru)打(da)開(kai)狀態(tai)(tai)，內部(bu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)接收到到位信(xin)號(hao)，控制電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)停(ting)止(zhi)轉動(dong)，夾(jia)管閥保持(chi)打(da)開(kai)狀態(tai)(tai)。

在閥(fa)(fa)門(men)使用過程之中，更(geng)高的(de)(de)(de)密(mi)(mi)封性能(neng)夠(gou)保(bao)證內部精密(mi)(mi)元件不受損(sun)傷，而目(mu)前性能(neng)1可靠的(de)(de)(de)管(guan)夾閥(fa)(fa)也能(neng)夠(gou)擁(yong)有更(geng)好(hao)(hao)(hao)的(de)(de)(de)密(mi)(mi)封襯套其(qi)本(ben)身的(de)(de)(de)密(mi)(mi)封面積更(geng)大，并且在其(qi)松散(san)顆(ke)粒的(de)(de)(de)運(yun)輸過程之中，其(qi)密(mi)(mi)封區域仍舊能(neng)夠(gou)保(bao)持(chi)良好(hao)(hao)(hao)的(de)(de)(de)密(mi)(mi)封效果(guo)，就此而言(yan)管(guan)夾閥(fa)(fa)的(de)(de)(de)使用更(geng)大程度上改(gai)善了(le)其(qi)閥(fa)(fa)體(ti)(ti)(ti)的(de)(de)(de)密(mi)(mi)閉(bi)性和流(liu)體(ti)(ti)(ti)的(de)(de)(de)控(kong)制效果(guo)，讓這種(zhong)管(guan)夾閥(fa)(fa)的(de)(de)(de)工業流(liu)體(ti)(ti)(ti)輸送能(neng)力得到了(le)更(geng)好(hao)(hao)(hao)的(de)(de)(de)改(gai)進。

總之使用(yong)高品(pin)1質的(de)(de)(de)管夾閥(fa)很(hen)大程度(du)上(shang)維持(chi)了其閥(fa)門輸送(song)的(de)(de)(de)良(liang)好性能，夾管閥(fa)廠家(jia)，而在這種(zhong)管夾閥(fa)的(de)(de)(de)使用(yong)之下(xia)，相應的(de)(de)(de)閥(fa)體(ti)設計標(biao)準也得到了不斷的(de)(de)(de)改(gai)進(jin)，讓(rang)這種(zhong)放心(xin)的(de)(de)(de)管夾閥(fa)更好的(de)(de)(de)提高流體(ti)輸送(song)的(de)(de)(de)工藝，同樣也能夠讓(rang)各種(zhong)液(ye)體(ti)輸送(song)的(de)(de)(de)安(an)全(quan)性和穩定性不斷改(gai)進(jin)。
