Explosion test rubber O-ring

Rubber is super-elastic material, with good reversible deformability, wear and corrosion resistance, etc. have been widely used in various places rubber O-ring seal structure is simple and easy to install, is a common seal products based on rubber ring seal mechanism no seal can not achieve zero leakage, the leakage rate is an important parameter seal design. Explosive containers typically use rubber O-ring seal mating flange, explosion damage can be limited within a certain range of personnel, equipment and environment to provide protection for the explosive effects shall provide test.

After the explosion experiments typically produce within the container temperature, high pressure explosion products, quasi-static pressure rise within the vessel, a large number of high-temperature filling in the role of shock piled flange seal, seal face temperature, high pressure test. Pressure is the driving force of the rubber O-ring leak, the higher the pressure, the greater the leakage; high temperature rubber O-ring is likely to cause structural damage, reduced contact stress, but also make the leak rate increases. Therefore, it is necessary to experiment with rubber O-ring studies at different temperatures, the sealing performance under pressure, to provide a reference for the selection and design of the ring, in order to ensure the security of the explosion of the container.

 

Viton rubber O-ring leak rate assessment results, showing that the device can simulate the rubber seal in the explosion vessel heating, insulation and cooling process, and the establishment of a direct relationship between the seal leak rate and pressure, temperature, experimental temperature and pressure control flexibility.
