Pressure relief valve assembly

Abstract

The present application provides a kind of pressure relief valve assembly, it is related to valve technical field.The pressure relief valve assembly includes pressure relief valve;Pressure relief valve is equipped with pressure relief port, the circumferential side wall of pressure relief valve close to pressure relief port is pressure relief part;The material of pressure relief part is ceramic, and the outer surface of pressure relief part is covered with frosted layer, and the material of frosted layer is metal or alloy.The pressure relief valve assembly can prevent water droplets from condensation of water vapor and adhering to the inside of pressure relief part by the ceramic pressure relief part, thereby preventing frost from forming around the pressure relief port, and the pressure relief valve assembly can make water vapor on the outside of pressure relief part more easily heat-conducted with the frosted layer made of metal or alloy rather than condensing to form water droplets, which can effectively prevent frost from forming on the outside of pressure relief port.In addition, the structure of the frosted layer is similar to the structure of a lotus leaf, under the lotus effect, the frosted layer can form an air film using the multiple protrusions on its surface, thereby repelling water droplets using air tension, further preventing frost from forming on the outside of the pressure relief port.
