Research Progress on Fire Protection for Emergency Valve Actuator in Petrochemical Storage Tank Farms
In order to enhance the safety performance of emergency valve actuators in petrochemical storage tank areas during fires,in this paper,grounded in the fire safety requirements of the petrochemical industry,the current status of the fire pro-tection equipment of emergency valve actuators and its applications at home and abroad was summarized,and prevalent full-scale fire experiment methods along with fire cover tests conducted under petrochemical environments were reviewed. It is found that there are problems of inconsistencies in testing methodologies and judgement criteria for the fire-resistant proper-ties of different emergency valve actuators. In response to the current fire protection needs of China's petrochemical industry,judgement indicators for the fire resistance of typical fire covers are proposed,and test standards for the fire resistant perform-ance of emergency valve actuators are illustrated,so as to realize the normalized management for the fire resistant perform-ance of the fire cover.
