Gaskets are made of metal or non-metallic plate-like materials and are made by cutting, stamping or cutting processes, and are used for sealing connections between pipelines and between mechanical parts of machinery and equipment. Metal ones include copper gaskets, stainless steel gaskets, iron gaskets, aluminum gaskets, etc. Non-metallic ones include asbestos gaskets, non-asbestos gaskets, paper gaskets, rubber gaskets, etc.
The inner diameter of the sealing gasket of the unmanned vending gearbox should be slightly larger than the inner diameter of the pipeline, and the difference between the two inner diameters is generally 2 times the thickness of the sealing gasket to ensure that after pressing, the inner edge of the sealing gasket does not extend into the container or pipeline, so as not to hinder the flow of fluid in the container or pipeline. The nuts should be tightened sequentially. However, it should not be twisted once to reach the design value.
Generally, it should be cycled at least 2~3 times so that the stress distribution of the sealing gasket is uniform. Oil-resistant asbestos rubber gasket is made of high-quality asbestos fiber, oil-resistant fiber, filler, colorant, etc., which is widely used in pipelines and equipment in the petroleum and chemical industries, and the corresponding grade of models can be selected according to working conditions.
