止回阀

YH44H/Y自密封旋启止回阀

法兰连接的旋启式止回阀适用于公称压力 PN1.6～16.0Mpa，工作温度-29～550℃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、酸性介质等。产品结构特点1.产品设计制造按GB12236设计标准，结构合理,密封可靠，外形美观。
2.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。
3.可采用各种配管法兰标准及法兰密封面型式，满足各种工程需要及用户要求。
4.阀体材料品种齐全，填料、垫片根据实际工况或用户要求合理选配，能适用于各种压力、温度及介质工况。
5.阀瓣围绕阀座外的销轴旋转，减少关闭时发生猛烈冲击。
6.销轴与阀瓣连接采用内装式的销轴结构，减小外泄漏点，使用更可靠。主要零件的材料说明
