RETZ工业/美国瑞茨,我们一直致力于流体控制领域的持续创新,始于2005……耐酸碱防腐蚀衬氟蝶阀独特设计的非常适用于液体、粉末、或气体状态下的腐蚀性和研磨性工艺介质关闭、流量控制和节流
产品详情 Product details
(耐酸碱防腐蚀)衬氟蝶阀在阀杆轴部的密封。在上下密封轴处采用独特设计的四级弹性垫与O型圈相结合的密封结构,更适应高温与低温使用环境的温差变化。弹性密封机构体使两平面不透气的紧密配合,始终保持低扭矩。在端面上的衬里提供了比较宽的密封面,阀瓣采用直板式设计降低流通的阻力,提高在DCS控制系统中调节微动流量的Cv值 RETZ (Acid and alkali resistant and anti-corrosion) sealing of fluorine lined butterfly valve at the stem shaft. The upper and lower sealing shafts adopt a sealing structure of unique design of four stage elastic pads combined with O-rings, which is more suitable for the temperature difference changes in high-temperature and low-temperature service environments. The elastic sealing mechanism body makes the two planes airtight and closely fit, and always maintains the lowest operating torque. The lining on the end face provides a wide sealing surface. The valve disc adopts a straight plate design to minimize the flow resistance and improve the Cv value for regulating the inching flow in the DCS control system
