电动直流对焊截止阀

电动直流对焊截止阀概述
      截止阀具有结构紧凑，密封面不易磨损、擦伤；密封性能好，制造与维修方便；启闭时阀瓣行程小，启闭时间短；阀门高度小，工艺性能好和适用范围广等特点；是一种广泛使用的截断阀，用于截断或接通管路中的介质，一般不用于调节流量。引进磅级高压电站截止阀适应于ANSI CLASS 1500-3500LB，工作-29～570度的石油，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：水石油，蒸汽等。磅级电站截止阀也称电站截止阀，电站截止阀主要适用于火力电站各种系统的管路上，切断或接通管路介质。电站截止阀适用介质∶水、蒸气等非腐蚀性介质。电站截止阀与其他截止阀产品相比的特点是高温高压，*的自密封设计，压力越高，密封越可靠。
 
电动直流对焊截止阀结构优势与特点：
1，磅级引进高压电站截止阀产品设计制造按ANSIB16.34,E101标准，可与进口设备直接配套使用．
2，阀门中腔采用自紧式密封结构，内腔压力越高密封性能越好，支管两端为对焊接，适应不同的接管要求．
3，引进磅级高压电站截止阀的阀体，阀盖有足够的强度和刚性．通道流畅，流体阻力小．
4，阀瓣和阀座的密封面采用司太立（SLITE）钴革硬质合金堆焊而成，密封面硬度高，耐磨，耐高温，耐腐蚀，抗擦伤性能好，使用寿命长．
5，阀杆经调质和表面氮化处理，有良好的抗腐蚀性和抗擦伤性．
6，阀盖填料函深度合理，填料加缓蚀剂，密封可靠，开关平稳．
7，级高压电站截止阀门具有上密封结构，保证阀门开启运行时不经阀杆外漏．
8，电动电站截止阀的开启和关闭由电动装备来控制，电动装置分别配有电机，减速机，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．

用途
焊接连接的截止阀适用于公称压力PN20～32MPa及P54/100V-P57/170V ，工作温度≤540℃（其中P57/170V工作温度为570℃）的石油 、化工 、水力 、火力电站各种系统的管路中，切断或接通管路介质,，适用介质为：水、油品、蒸汽等。操作方式有：手动、齿轮传动、电动等。

    是采用高品质截止阀和高精度电动执行器组成。结构合理，性能优良，造型美观，适用的压力范围广，主要用来接通或截断管路中的介质，具有耐磨、耐高温，抗擦伤性能好、使用寿命长等优点。据我集团各产品生产工艺的特点，针对各种介质，作阀门选用的一般要求如下： 截止阀具有结构紧凑，密封面不易磨损、擦伤；密封性能好，制造与维修方便；启闭时阀瓣行程小，启闭时间短；阀门高度小，工艺性能好和适用范围广等特点；是一种广泛使用的截断阀，用于截断或接通管路中的介质，一般不用于调节流量。 用途 焊接连接的截止阀适用于公称压力PN20～32MPa及P54/100V-P57/170V ，工作温度≤540℃（其中P57/170V工作温度为570℃）的石油 、化工 、水力 、火力电站各种系统的管路中，切断或接通管路介质,，适用介质为：水、油品、蒸汽等。操作方式有：手动、齿轮传动、电动等。
