偏心半球阀跟v型球阀的区别在哪 阀门厂家排名前50

偏心半球阀跟v型球阀的区别在哪：

偏心半球阀是一种具有旋转瓣的半球形阀门，其瓣体的一端连接在阀体的一端，另一端连接在阀杆上。瓣体在关闭时，将瓣口一侧的介质封闭，另一侧的介质从瓣口的另一侧流出。偏心半球阀的瓣体可以旋转，从而改变它的开度，从而改变流量，从而调节介质的流量。

V型球阀是一种具有V型瓣体的球形阀门，其瓣体分为上下两部分，每部分均为V形，当瓣体关闭时，它们会组合在一起，从而封闭介质的流动。当瓣体旋转时，上下两部分的V形开口会和形成一个连续的圆形开口，从而使介质流动，从而调节介质的流量。

总之，偏心半球阀和V型球阀的区别在于：偏心半球阀的瓣体为半球形，V型球阀的瓣体为V形；偏心半球阀的瓣体在关闭时，将瓣口一侧的介质封闭，V型球阀的瓣体在关闭时，上下两部分的V形开口会组合在一起，从而封闭介质的流动。
