美标不锈钢低温法兰闸阀说明介绍：

我厂生产的美标不锈钢低温法兰闸阀，阀门采用手轮转动开关启闭，阀门经过了低温处理，最低可以用到-196度超低温阀门的阀体依然不会受到影响，阀门的阀体材质为不锈钢304阀体，阀门的连接方式为法兰连接，低温闸阀具有良好的硬密封效果，可以对管道起到良好的密封性能，防泄漏性能强，阀门材质与阀瓣材质皆为不锈钢304材质，具有极强的耐腐蚀性能，阀门的阀杆采用加长杆，使用更加方便。

美标不锈钢低温法兰闸阀的工作原理：

美标不锈钢低温法兰闸阀的基本工作原理，就是通过转动手轮，阀门的手轮带动阀门旋转升降阀板，将阀板升起或下降，阀板升起，阀门打开，介质通过；阀瓣下降，阀门关闭，阀板压在阀座上时，阀门关闭，阀门的介质流向是由上向下，阀门关闭时，阀门是硬密封阀门，所以管道压力越大，阀门密封性越好，低温法兰闸阀具有良好的耐腐蚀性，且阀门的结构简单，方便与在管道中的安装，适合用于多种场所的管道中。
