液氨储罐阀门自动关闭装置的设计研究

Automatic shutdown device for outlet of ammonia storage tank

本文对液氨储罐阀门自动关闭装置进行研究,该自动关闭装置无须抢险人员亲自关闭出口阀门,仅靠液氨系统内部的压力变化,实现阀门的自动关闭。

This article presents the automatic shutdown device for the valve of ammonia storage tank,which can realize selfclosing of the outlet valve by inner pressure changes of the ammonia system instead of manual operation.
