2、pa-50.0Mpa。工作温度：-196-650。连接方式：内螺纹、外螺纹、法兰、焊接、对焊、承插焊、卡套、卡箍。驱动方式：手动、气动、液动、电动。 产品详细信息产品介绍：旋启式止回阀是靠管路中介质本身的流动产生的力而自动开启和关闭的，属于一种自动阀门。止回阀用于管路系统，其主要作用是防止介质倒流、防止泵及其驱动电动机反转，以及容器内介质的泄放。止回阀产品还可用于给其中的压力可能升至超过主系统压力的辅助系统提供补给的管路上 。应用范围：法兰式旋启式止回阀适用于压力PN16160工作温度-29550的石油、化工、制药、化肥、电力行业等各种工况的管路上，旋启止回阀适用介质为水、油品、蒸汽、酸性介质
3、等。 结构特点：旋启式止回阀的采用内装摇臂旋启式结构，阀门的所有启闭件都装于阀体内部，不穿透阀体，除了中法兰部位用密封垫片和密封环外，整体没有外漏点，杜绝阀门外泄的可能。旋启式止回阀摇臂和阀瓣连接处采用球面连接的结构，使得阀瓣在360C范围内有一定的自由度，有适当的微量位置补偿。标准规范：设计制造标准：GB/T 12236-2008 结构长度标准：GB/T 12221-2005连接法兰标准：GB/T 9113压力温度等级：GB/T 12224-2005试验检验标准：GB/T 13927-2008旋启式止回阀主要性能规范型号公称压力 PN/MPa试验压力PS(MPa)工作温度（）适用介质工作温度
