　　产品详情 Product details

　　三偏心硬密封对夹蝶阀采用了径向动平衡密封系统，通过优化设计，蝶板的进出口两侧受力近似平衡，阀门达到进出口双向可靠的密封性能的同时，有效降低了阀门的开启力矩The triple eccentric hard seal wafer butterfly valve adopts a radialdynamic balance sealing system. Through optimization design, the forces on bothsides of the inlet and outlet of the butterfly plate are approximatelybalanced. The valve achieves reliable sealing performance in both directions,while effectively reducing the opening torque of the valve

　　偏心结构说明Triple eccentricstructure

　　一个偏心: 阀杆偏离阀座中心线, 从而在整个阀座上拥有一个完整的密封接触 Theshaft is offset behind the seat axis to allow complete sealing contact aroundtheentire seat

　　第二个偏心: 阀杆偏离管路及阀门中心线. 可以减少阀门在开关过程中, 对阀座与密封面之间的摩擦 The shaft centerline is offset from the pipe and valve whichprovides interference free opening and closing of the valve

　　第三个偏心: 阀座的圆锥度设计消除了在阀门开启和关闭过程中的磨擦,使密封圈的密封力均匀的分布在阀座上 Theseat cone axis is offset from the shaft centerline to eliminate frictionduringclosing and opening and to achieve uniform compressive sealing around theentire seat.

　　● 采用独立的整体锻造阀座圈, 材料最常用不锈钢SS304, 保证了密封圈的抗腐蚀性能和强度 Renewable Body Seat Ring made of integral forged, minimum stainless steel 304to guarantee the resistance to corrosion and strength

　　● 阀座采用斜锥面设计, 通过磨削精加工工艺表面粗糙度可达Ra 0.4 Seat Ring with oblique conedesign, with high quality machining to Roughness Ra 0.4

　　● 阀座还可选用堆焊/喷涂司太力工艺和渗氮、镀铬等工艺处理, 拓宽了不同工矿的应用要求 Seat Ringoption with overlay / spay Stellite / Nitride / Chrome plated and so ondifferent treatment process used for different application

　　● 阀座独立安装入阀体, 可实现维修和更换的目的 Seat Ring independentinstall into the body, Ensure a replacement and renewable service

　　● 双向密封设计, 在上游或下游流质压力下,均能保证气泡级零泄漏 The renewableBody Seat provide a bi-directional bubble tight on upstream and down streamservice
