LNG低温过程控制先导式安全阀的设计开发

摘要

According to characteristics of pressure relief technology for the LNG cryogenic high-pressure system,the pilot LNG safety valve was developed to control variable pressure,temperature and flow in the LNG production so that the structure of LNG safety device can become more compact along with high safety.%根据LNG低温高压系统安全减压技术特点,开发了先导式LNG安全阀.该阀用于控制变压、变温、变流量的LNG生产过程,使LNG安全装置结构更精巧,安全性更高.
