电站高温高压安全阀是电站锅炉运行的有效保障,是最重要的,也是最后一道安全泄压装置。最近几年国家对锅炉压力容器安全越发重视,以及实行减能减排,对高温高压安全阀的有效安全性、密封性、回座灵敏度、节能性等提出了更高的要求。因此对电站高温高压安全阀结构的改进已迫在眉捷。新型结构的安全阀的总体结构如图1所示。
Power station high temperature and high pressure safety valve is an effective protection of power plant boiler operation, is the most important, but also the last one safety relief device. In recent years, the state attaches more importance to the safety of boilers and pressure vessels, as well as the implementation of energy-saving emission reduction, high-temperature high-pressure safety valve safety, sealing, back seat sensitivity, energy-saving and put forward higher requirements. Therefore, the high temperature and pressure relief valve structure of the power plant has been imminent. The new structure of the overall structure of the safety valve shown in Figure 1.
