r 详细介绍r
rr r ZSHV气动V型调节球阀概述r 该系列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,它将球阀和蝶阀的最佳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。气动V型调节球阀具有有结构紧凑、重量轻、动作灵敏、阀容量大、流量特性精确、拆装方便等优点。公司具有雄厚技术实力和丰富的阀门制造经验,拥有一支不断创新的优秀团队,专心致力于工业阀门的研发与制造。公司加工设备先进,检测手段齐全,具有严格的品质管理和质量保证体系,所有产品都建有可追溯性,完整的质量档案,为完善的售后服务提供坚实的基础。 r r r
r(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; r r r (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;
r(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;
r(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,特别适用于管线结垢冻结或含有纤维和颗粒固体场合。
r适用于高粘度、悬浮液、纸浆等不干净、含纤维介质场合。采用直连方式与执行机构连接,具有结构紧凑、尺寸小、重量轻、阻力小、动作稳定可靠等优点。执行机构根据用户要求配置UNIC、PSQ、HQ、DHL等型号电子式电动执行机构或GTX、AL等气动活塞式执行机构。
