Aimed at the problem of high temperature sealing for a certain type of product acceptance test ( medium max?imum temperature of 300 ℃) , a new type of high?temperature sealing device was designed based on the original test equipment. The device was mainly composed of mounts,up/down clamping screw cap and sealing ring.The sealing ring was the key part,which was made of a new special modified PTFE material that can withstand a temperature of 320 ℃. The designed high temperature sealing device was proved to have a good high?temperature sealing effect by practice test.
