必威体育精装版垫片选用（Latest gasket selection） The gasket is made of paper, rubber or copper sheet, placed between the two surfaces to strengthen the sealing material and to prevent the leakage of the fluid from the sealing element between the static and closed covers. Definition edit Shim Shim Gaskets (gasket) are mechanical seals between two bodies, usually used to prevent pressure, corrosion, and natural heat expansion, cold contraction and leakage between two bodies. Because machined surfaces are not perfect, gaskets can be used to fill the irregularity. Gaskets are usually made of sheet materials such as cushion paper, rubber, silicone rubber, metal, cork, felt, neoprene, nitrile rubber, fiberglass or plastic polymers (such as Teflon). Gaskets for specific applications may contain asbestos. A gasket (washer) is a hole (usually in the middle) of a thin plate (usually round), usually used to distribute threads of load fasteners. Other uses are used as spacers, springs (Baer, gasket, wave washer), wear-resistant pads, pre display devices, and locking devices. Rubber gaskets are also used on taps (valves) to cut off flowing liquids or gases. Rubber or silicone gaskets are also available to reduce vibration of the fan. Usually the outer diameter of the gasket is about two times the inside diameter. Installation requirements edit Gasket - gasket mounting requirements 1, gasket gasket and flange sealing surface should be cleaned, shall not have any influence on the sealing performance of scratches, spots and other defects exist. 2, the sealing gasket than the flange sealing surface diameter should be small, the gasket diameter should be slightly larger than the inner diameter of the pipe diameter, two difference 2 times the thickness of the gasket, to ensure that the gasket is compressed, not into the inner edge of a container or a pipe, so as not to impede the flow of liquid container or pipeline flow. 3, the gasket preload should not exceed the design requirements, so as to avoid
