一、Z43WF手动平板闸阀--概述

Z43WF 手动平板闸阀适用于天然气,石油,化工,环保,城市管道,燃气管线等输送管线,放空系统和汽储存装置上,用作启闭设备。适用于天然气开采和净化的长输管线。

二、Z43WF手动平板闸阀--特点

1.阀座的密封结构应为弹性有预紧力,上、下游密封座同时密封的结构。阀座与密封物间始终为面对面密封。

2.阀座有自清洗功能,并且在阀门开启或关闭过程中不受气流的直接冲刷。阀座应由有润滑、不磨损材料制成。

3.阀门执行机构的故障不会影响到阀门的其它部分,维修和更换工作能够在不拆下阀门的情况下进行。

(1) 轭架套管–铝青铜轭架套管配置针形止推轴承,最大程度减少操作扭矩。

(2) 阀杆–螺纹长度直到托架;销钉和点焊;具有稳定性。

(3) 压力密封–结构简单,配置分段扣环和镀银低碳钢垫圈,有助于拆卸和实现最好的阀帽密封。

(4) 阀座环–焊接阀座环垂直于流动通道,易于维护。

(5) 执行机构–这些阀门可以配置电动、液动或气动执行机构。DN300以下配置标准手动手轮,DN350以上配置斜齿轮操作机构。

(6) 轭架–完全装配式轭架通过抗震测试,易于维护和安装执行机构。

(7) 压盖–两件式,自调节压盖,避免被弹出。

(8) 整体后座–硬面,使用寿命最长。

(9) 阀瓣–弹簧负载阀瓣能够自行调节,减少执行机构的扭矩需求。

(10) 整体止动–整体铸造托架止动装置,定位组装的托架阀瓣,使得阀座更加稳定可靠。
