·用途
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、制药、化肥、电力行业等各种工况的管路上。适用介质为:水、油品、蒸汽、酸性介质等。
·结构优势与特点
1、产品按国家标准GBl2236设计制造,结构合理,密封可靠,性能优良。 2、阀瓣、阀座密封面采用铁基合金或司太立(stellite)钴基硬质合金堆焊而成,耐磨、耐高温、耐腐蚀、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、垫片可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、阀瓣转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结构,不存在外泄漏点,使用更可靠。
