安全阀是各类压力容器上的重要安全附件之一。根据国家有关文件要求,承受压力大于0.1MPa的容器上都要安装安全阀。正确地安装与使用安全阀,是保证压力容器及其附属设备安全经济运行和人身安全的重要环节。但若安装不当,安全阀同样可成为危及设备安全的隐患。目前我国颁布的有关压力容器安全技术标准和监察规程中,对安全阀的安装使用与维护的方法都有明确的要求,概括起来主要有四方面的内容:一是数量上的要求;二是安装位置与方向的要求;三是排放能力的要求;四是安全维护的要求。这些标准和规程为安全阀的正确使用与管理提供了较全面的技术理论。但是,所
Safety valve is one of the important safety accessories on all kinds of pressure vessels. According to the relevant documents of the state, pressure relief valves with pressure greater than 0.1MPa shall be installed on the container. The correct installation and use of safety valve, is to ensure the safe operation of pressure vessels and their ancillary equipment and an important part of personal safety. However, if improperly installed, safety valve can also be a threat to the safety of the equipment. At present, China promulgated the pressure vessel safety technical standards and monitoring procedures, the safety valve installation and maintenance methods have clear requirements, summed up in four main aspects: First, the number of requirements; the second is to install Location and direction requirements; third is the emission capacity requirements; Fourth, safety and maintenance requirements. These standards and procedures for the correct use and management of safety valve provides a more comprehensive technical theory. However,
