液化天然气低温焊接截止阀说明介绍：

我厂生产的液化天然气低温焊接截止阀，阀门采用手轮转动开关启闭，阀门经过了低温处理，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，阀门的连接方式为焊接连接，低温截止阀具有良好的密封效果，可以对管道起到良好的密封性能，防泄漏性能强，阀门的阀瓣采用四氟乙烯密封，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。

液化天然气低温焊接截止阀的工作原理：

液化天然气低温焊接截止阀的基本工作原理，就是通过转动手轮，阀门的手轮带动阀门旋转升降阀瓣，将阀瓣升起或下降，阀瓣升起，阀门打开，介质通过；阀瓣下降，阀门关闭，阀瓣压在阀座上时，阀门关闭，阀门的介质流向是由上向下，阀门关闭时，管道压力越大，阀门密封性越好，低温焊接截止阀具有良好的耐腐蚀性，且阀门的结构简单，体积小，重量轻，方便与在管道中的安装，适合用于多种场所的管道中。
