High-temperature-resistant pressure vessel cover

The invention discloses a high-temperature-resistant pressure vessel cover .The high-temperature-resistant pressure vessel cover comprises a cover body and a plurality of tooth blocks arranged on the periphery of the cover body .A high-temperature-resistant coating is sprayed on the cover body and the tooth blocks .The high-temperature-resistant pressure vessel cover has the advantages that the high-temperature-resistant coating is sprayed on the cover body and the tooth blocks of the pressure vessel cover and well adheres to the pressure vessel cover without bubbling or shedding, so that the high temperature resistance of the pressure vessel cover is further improved, and it is avoided that the pressure vessel cover deforms in a high-temperature environment. 本发明公开了种耐高温的压力容器盖，包括盖体本体和设置于盖体本体周边的多个齿块，盖体本体和齿块上均喷涂有耐高温涂料。有益之处在于：本发明的压力容器盖的盖体本体和齿块上均喷涂有耐高温涂料，该涂料与压力容器盖的附着性良好、不起泡、不脱落，进步提升了压力容器盖本身的耐高温性能，避免压力容器盖在高温环境下发生变形。
