Based on the fact of increasing leakage accidents of the petrol transport in recent years,new corresponding policies have been formulated by many countries.Since the original petrol transport has no longer adapted to the present security situation,a new control valve has become a growing trend with functions of bidirectional emergency switching-off,automatic turn-off under over-temperature and high-level protection.Thus,this dissertation will discuss the advantages of the new equipment and the existing problems of the present research and relevant solutions in order to provide theoretical help to technicians,in hopes of enhancing the safety of hazardous chemicals transportation,reducing accidents and promoting the development of the Chinese army on the field of chemicals transporting.%近年来运加油设备泄露事故呈上升趋势,各国为此也制定了相关的新标准,原有的运加油设备不再适应新的安全形势,因此具备应急切断、超温自动关断和高液位保护功能为一体的双向紧急切断高液位新型控制阀成为当今研究和应用的趋势.本文根据相关新制定的标准,结合国内外相关发展情况,对此种新型控制阀的优点及主要存在的研究问题和相关解决方法做简单概述,旨在为相关技术人员提供参考,提升危化品运输安全性,达到降低安全事故发生率的目标,推动国家军队危化品运输健康发展.
