电(dian)动截(jie)止阀(fa)(fa)是一种强制(zhi)(zhi)密(mi)封式阀(fa)(fa)门(men)(men)，用于介质(zhi)的(de)(de)(de)(de)切断(duan)、调节和节流(liu)。它的(de)(de)(de)(de)阀(fa)(fa)杆开启(qi)或关(guan)闭(bi)(bi)的(de)(de)(de)(de)行程(cheng)相对较(jiao)短，并具(ju)有非(fei)常可靠的(de)(de)(de)(de)切断(duan)动作(zuo)(zuo)(zuo)。在关(guan)闭(bi)(bi)阀(fa)(fa)门(men)(men)时，必(bi)须施(shi)加压(ya)力(li)(li)以确保密(mi)封面不泄漏(lou)。当介质(zhi)进(jin)入阀(fa)(fa)门(men)(men)时，操作(zuo)(zuo)(zuo)力(li)(li)必(bi)须克服阀(fa)(fa)杆和填料的(de)(de)(de)(de)摩擦力(li)(li)以及由介质(zhi)的(de)(de)(de)(de)压(ya)力(li)(li)产生的(de)(de)(de)(de)推力(li)(li)。关(guan)闭(bi)(bi)阀(fa)(fa)门(men)(men)所(suo)需的(de)(de)(de)(de)力(li)(li)大于开启(qi)阀(fa)(fa)门(men)(men)的(de)(de)(de)(de)力(li)(li)，因此阀(fa)(fa)杆的(de)(de)(de)(de)直(zhi)径必(bi)须较(jiao)大，以避免阀(fa)(fa)杆顶(ding)弯故障的(de)(de)(de)(de)发生。电(dian)动截(jie)止阀(fa)(fa)具(ju)有一些(xie)优(you)点。首先，它的(de)(de)(de)(de)结构简单，制(zhi)(zhi)造和维修比(bi)较(jiao)方便。其次，它的(de)(de)(de)(de)工作(zuo)(zuo)(zuo)行程(cheng)小(xiao)，启(qi)闭(bi)(bi)时间短。第三，它的(de)(de)(de)(de)密(mi)封性好，密(mi)封面间的(de)(de)(de)(de)磨(mo)擦力(li)(li)小(xiao)，寿命(ming)较(jiao)长。严格的(de)(de)(de)(de)质(zhi)量把控，保证每一个电(dian)动阀(fa)(fa)门(men)(men)的(de)(de)(de)(de)安全与稳定。奉贤区电(dian)动阀(fa)(fa)门(men)(men)作(zuo)(zuo)(zuo)用

电(dian)(dian)(dian)(dian)(dian)动(dong)(dong)塑(su)(su)料(liao)球阀(fa)在(zai)(zai)管(guan)(guan)道中(zhong)的(de)主要功能(neng)是(shi)切断(duan)、分(fen)配(pei)和(he)改变介质(zhi)的(de)流(liu)(liu)(liu)动(dong)(dong)方向。这是(shi)一(yi)种新型阀(fa)门(men)，近年(nian)来(lai)(lai)在(zai)(zai)很(hen)多(duo)领域得到(dao)多(duo)应(ying)用(yong)。首(shou)先，电(dian)(dian)(dian)(dian)(dian)动(dong)(dong)塑(su)(su)料(liao)球阀(fa)的(de)流(liu)(liu)(liu)体(ti)(ti)阻力小(xiao)，其阻力系(xi)数(shu)与同长度(du)的(de)管(guan)(guan)段(duan)相等。这意味着在(zai)(zai)使用(yong)电(dian)(dian)(dian)(dian)(dian)动(dong)(dong)塑(su)(su)料(liao)球阀(fa)时(shi)，流(liu)(liu)(liu)体(ti)(ti)的(de)阻力很(hen)小(xiao)，可(ke)(ke)以(yi)保证管(guan)(guan)道中(zhong)的(de)流(liu)(liu)(liu)动(dong)(dong)效(xiao)率。其次，电(dian)(dian)(dian)(dian)(dian)动(dong)(dong)塑(su)(su)料(liao)球阀(fa)的(de)结构(gou)简(jian)单，体(ti)(ti)积小(xiao)，重量轻(qing)。它(ta)(ta)采(cai)用(yong)低温截(jie)止阀(fa)关(guan)闭件(jian)，通过阀(fa)瓣沿阀(fa)座中(zhong)心线移动(dong)(dong)来(lai)(lai)控(kong)(kong)制流(liu)(liu)(liu)动(dong)(dong)。因此，它(ta)(ta)的(de)结构(gou)非(fei)常简(jian)单，体(ti)(ti)积小(xiao)，重量轻(qing)，非(fei)常适合作为切断(duan)、调(diao)节(jie)和(he)节(jie)流(liu)(liu)(liu)使用(yong)。第三(san)，电(dian)(dian)(dian)(dian)(dian)动(dong)(dong)塑(su)(su)料(liao)球阀(fa)具有(you)紧密(mi)(mi)可(ke)(ke)靠的(de)特(te)点。目前，电(dian)(dian)(dian)(dian)(dian)动(dong)(dong)塑(su)(su)料(liao)球阀(fa)的(de)密(mi)(mi)封面材料(liao)多(duo)使用(yong)塑(su)(su)料(liao)，能(neng)够保证密(mi)(mi)封性(xing)。同时(shi)，在(zai)(zai)真空系(xi)统中(zhong)也得到(dao)多(duo)使用(yong)。因此，在(zai)(zai)截(jie)断(duan)或接通管(guan)(guan)路中(zhong)的(de)介质(zhi)时(shi)，它(ta)(ta)具有(you)很(hen)好(hao)的(de)密(mi)(mi)封性(xing)能(neng)。此外，它(ta)(ta)还可(ke)(ke)以(yi)用(yong)于流(liu)(liu)(liu)体(ti)(ti)的(de)调(diao)节(jie)与控(kong)(kong)制，是(shi)工(gong)业自动(dong)(dong)化过程控(kong)(kong)制的(de)重要组成部分(fen)。
