摘　　要：介绍了安全阀的结构类型、工作特性及适用工况,分析和比较了先导式安全阀与常规弹簧载荷式安全阀技术发展过程、特殊场合状态和远程使用要求。从结构原理出发,结合具体工况需求给出了近年来开发研制的多种新型先导式安全阀。Since the pilot-operated safety valve has obvious advantages compared with the conventional spring-loaded safety valve,it has been used more and more widely. According to the constantly changing market demand,a variety of newpilot-operatedsafety valves have been developed. This article starts from the structural principle,combined with the requirements of specific operating conditions,the technical development path of the pilot-operated safety valve was introduced in detail.
