V型球阀 产品信息

一、V型球阀产品详细介绍:

上明牌V型球阀是一种芯阀座采用金属,或金属对聚四氟乙烯密封配合的旋转球阀,它将球阀和蝶阀的控制特性结合成一体,既可用作控制调节阀,又可作关断切断阀。其主要特点是:
(1)不带任何管接头的整体式阀体,因此不受管道或螺栓应力影响,并且由于阀体无任何管接头,故耐压壳体不会受压力“突变”的影响;
(2)具有一个V型阀体,即使在小流量或高粘度介质的情况下,也可在整个量程范围内,保证控制的精确性;
(3)防漏耐用的阀座在其外径处衬有带不锈钢内芯PTFE杯形或是O型密封圈,阀座用截面较大的钨钴硬质合金制成,通过一个合金的波纹弹簧进一步增强了阀座的结构;
(4)当阀门关闭时,V型缺口与阀座之间产生楔形剪切作用,并既具有自洁功能又可防止球芯卡死,特别适用于高粘度、悬浮液、纸浆等不干净、含纤维介质场合。
