偏(pian)心半球(qiu)阀(fa)(fa)(fa)重点在(zai)(zai)于(yu)偏(pian)心。即(ji)阀(fa)(fa)(fa)轴(zhou)和(he)半球(qiu)体(ti)的(de)中(zhong)心线有一个(ge)尺寸偏(pian)量。这个(ge)偏(pian)心使球(qiu)芯(xin)与阀(fa)(fa)(fa)座(zuo)(zuo)之间的(de)接(jie)触存(cun)在(zai)(zai)很短，只在(zai)(zai)关闭和(he)打开阀(fa)(fa)(fa)门的(de)瞬间存(cun)在(zai)(zai)接(jie)触。减少了(le)阀(fa)(fa)(fa)芯(xin)与阀(fa)(fa)(fa)座(zuo)(zuo)的(de)磨损。延长了(le)阀(fa)(fa)(fa)门使用(yong)寿命.

V型(xing)球(qiu)(qiu)阀(fa)的阀(fa)芯也是采用半球(qiu)(qiu)结(jie)构(gou)，重点在于(yu)阀(fa)芯上开有V型(xing)口(kou)，通过V型(xing)口(kou)可以控制更小(xiao)的流量，同时其流通能力比一般调节阀(fa)要(yao)大。所以其可调比远(yuan)远(yuan)超过普通调节阀(fa)。但是V型(xing)球(qiu)(qiu)阀(fa)球(qiu)(qiu)芯密封面与(yu)(yu)阀(fa)座始终(zhong)处于(yu)密切接触(chu)状态。阀(fa)轴与(yu)(yu)半球(qiu)(qiu)体中(zhong)心(xin)线(xian)处于(yu)流道(dao)中(zhong)心(xin)线(xian)，没有偏心(xin)结(jie)构(gou)。
