The seal without relative displacement of the two sealing surfaces during operation is a static seal. The sealing of the head and barrel of the pressure vessel, the seal of the reducer case and the cover, and the seal of the cylinder and cylinder head of the internal combustion engine are all static seals.
O-ring seal has long life, compact structure, convenient assembly and disassembly, and good sealing performance. Depending on the material, it can be used in the temperature range of -100 ℃ ~ 260 ℃ and its pressure of 100MPa. If you want to work under higher or lower temperature and pressure conditions, you need to choose the material to make it and use a metal hollow O-ring seal. He can work under 280MPa pressure and the temperature range is -250 ℃ ~ 650 ℃.
2. Gasket seal
Gasket sealing is the most commonly used form of static sealing. A gasket of different material is placed between the sealing surfaces of the two connectors, and then the threads or bolts are tightened to cause elastic and plastic deformation of the gasket. The unevenness can achieve the purpose of sealing. It includes between flanges, between bearing end covers and boxes, between flanges and flange covers, and so on.
