The shape of the rubber gasket needs to be determined based on the structure of the sealing component, the stress method, and the operating environment. The core is to ensure uniform contact, stable stress, and reliable sealing.
Common Shapes and Applicable Scenarios
Round Gaskets (including flat gaskets and perforated round gaskets): The most basic type, suitable for standard interfaces such as bolted connections and flange seals. Easy to install, widely used in mechanical equipment and piping systems.
Square/Rectangular Gaskets: Often used for large-area sealing surfaces, such as enclosure covers and electrical cabinet door seals. They provide more uniform compression and rebound force, preventing localized leaks.
O-Rings: A circular ring structure with a self-tightening effect, suitable for dynamic sealing (such as rotating shafts and piston rods), performing excellently in hydraulic and pneumatic systems.
Wave/Saddle-Shaped Gaskets: Utilize elastic deformation to compensate for pressure fluctuations and temperature changes. Commonly used in high-temperature, high-pressure, or frequently vibrating equipment, such as engines and compressors.
