2pc法兰球阀
    球阀的不锈钢管球体是浮动的,在介质压力作用下,球体能产生一定的位移并紧压在出口端的密封面上,保证出口端密封。浮动球球阀的结构简单,密封性好,但球体承受工作介质的载荷全部传给了出口密封圈,因此要考虑密封圈材料能否经受得住球体介质的工作载荷。这种结构,广泛用于中低压球阀。
    不锈钢管球阀和闸阀是同属一个类型的阀门,区别在它的关闭件是个球体,球体绕阀体心线作旋转来达到开启、关闭的一种阀门。
    不锈钢管球阀在管路中主要用来做切断、分配和改变介质的流动方向。法兰球阀标准GB/T21465-2008《阀门术语》中定义为:启闭件(球体)由阀杆带动,并绕阀杆的轴线作旋转运动的阀门。
