1、闸阀系列:Z43H/X铸钢平板闸阀的详细资料:产品名称：平板闸阀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。Z43型带导流孔单闸板式平板闸阀适用于天然气开采和净化的长输管线。平板闸阀的特点：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)规架套管-铝青铜辗架套管配置针形止推轴承，最

2、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)挽架-完全装配式轿架通过抗震测试，易于维护和安装执行机构。(7)压盖一两件式，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
