球閥(fa)按(an)其通(tong)道位(wei)置(zhi)可分(fen)為直(zhi)通(tong)式，三通(tong)式和直(zhi)角(jiao)式。后兩種球閥(fa)用于分(fen)配介質與改變介質的流向(xiang)。 【球閥(fa)按(an)結構形式可分(fen)】

浮動球(qiu)(qiu)(qiu)球(qiu)(qiu)(qiu)閥 球(qiu)(qiu)(qiu)閥的(de)球(qiu)(qiu)(qiu)體(ti)(ti)是浮動的(de)，在介質壓(ya)力(li)作(zuo)用下，球(qiu)(qiu)(qiu)體(ti)(ti)能(neng)產生一定(ding)的(de)位移(yi)并緊壓(ya)在出口端(duan)的(de)密封面上，保證出口端(duan)密封。浮動球(qiu)(qiu)(qiu)球(qiu)(qiu)(qiu)閥的(de)結構簡單，密封性好(hao)，但球(qiu)(qiu)(qiu)體(ti)(ti)承受工作(zuo)介質的(de)載荷全部傳給了出口密封圈，因(yin)此要考慮密封圈材料能(neng)否經受得住球(qiu)(qiu)(qiu)體(ti)(ti)介質的(de)工作(zuo)載荷。這(zhe)種(zhong)結構，廣泛用于中低壓(ya)球(qiu)(qiu)(qiu)閥。

法蘭(lan)(lan)球閥(fa)(fa)是(shi)(shi)一種廣泛應(ying)用(yong)(yong)的(de)(de)(de)管(guan)路控(kong)制設備，主(zhu)要用(yong)(yong)于(yu)各(ge)(ge)種工(gong)業系(xi)(xi)統中(zhong)。它廣泛用(yong)(yong)于(yu)石(shi)油(you)、化工(gong)、冶金、電力(li)、水處(chu)理(li)、城市燃氣、船舶等領域的(de)(de)(de)管(guan)道連接。在這些(xie)場景中(zhong)，法蘭(lan)(lan)球閥(fa)(fa)以其結構緊湊、操作方便、密封性(xing)能(neng)好、流通能(neng)力(li)大等特點被青(qing)睞。例如，球閥(fa)(fa)廠家(jia)，它是(shi)(shi)調節流體流量(liang)和(he)(he)(he)方向的(de)(de)(de)理(li)想(xiang)選(xuan)擇，江西(xi)球閥(fa)(fa)，可(ke)用(yong)(yong)于(yu)開(kai)閉或(huo)調節各(ge)(ge)種氣體、液(ye)體的(de)(de)(de)輸(shu)送，如分配系(xi)(xi)統、化工(gong)流程中(zhong)的(de)(de)(de)介質切(qie)換、石(shi)油(you)井口的(de)(de)(de)生產控(kong)制等。此外，法蘭(lan)(lan)球閥(fa)(fa)還常用(yong)(yong)于(yu)緊急切(qie)斷、隔(ge)離(li)或(huo)維(wei)護管(guan)道時(shi)的(de)(de)(de)臨時(shi)關閉，球閥(fa)(fa)哪家(jia)好，確(que)保(bao)系(xi)(xi)統的(de)(de)(de)安全(quan)運行(xing)。由于(yu)其靈活性(xing)和(he)(he)(he)可(ke)靠性(xing)，法蘭(lan)(lan)球閥(fa)(fa)在工(gong)業自動化和(he)(he)(he)過程控(kong)制中(zhong)扮演著重要角色(se)。
