产品采用标准

设计制造标准:ASME B16.34 E101
结构长度标准:ASME B16.10 E101
压力温度等级:ASME B16.34 E101
试验检验标准:API 598 E101

产品用途范围

磅级电站旋启式止回阀适用于Class1500~2500Lb、工作温度-29~570℃的石油、化工、火力电站等各种工况的管路上。电站旋启式止回阀适用介质为:水、油品、蒸汽等。

产品结构特点

1.产品设计制造按ANSI B16.34、E101标准,可与进口设备配备使用。
2.阀门中腔采用压力自紧式密封结构,内腔压力越高密封性能越好。
3.支管两端为对焊连接,适应不同的接管要求。
4.阀门耐压部件选用优质耐热合金钢制造,高温性能好,承受压力高,耐用、安全、可靠。
5.阀瓣、阀座的密封面采用司太立(stellite)钴基硬质合金堆焊而成,耐磨、耐高温,抗擦伤性能好、使用寿命长。
6.阀瓣围绕阀座外的销轴旋转,减少关闭时发生猛烈冲击。
7.内装式的销轴结构,减小外泄漏点,经阀门试压机检测证实其使用更可靠。
