产品用途范围

磅级电站闸阀适用于Class1500~3500Lb、工作温度-29~570℃的石油、化工、火力电站等各种工况的管路上切断或接通介质。适用介质为:水、油品、蒸汽等。

产品结构特点

1. 电站闸阀采用先进流道等径直通结构,极大降低了流阻系数与能量的损耗,显著提高了阀门使用寿命和性能。
2. 阀门中腔采用压力自紧式密封结构、密封性能好。支管两端为焊接结构。
3. 闸板与阀座密封面采用司太立(stellite)钴基硬质合堆焊而成,耐磨、耐高温、耐腐蚀、抗擦伤性能好。
4. 阀杆经调质和表面氮化处理,具有良好的抗腐蚀性和抗擦伤性。
5. 启闭件的结构可根据用户要求设计成单板、双板、平行双板等不同形式。
6. 电动闸阀的开启和关闭由电动装置来控制,电动装置分别配有专用电机、减速器、转矩控制机构,现场操作机构,手动、电动切换机构。除就地操作外,还可进行远距离操作。
