Description

Corrosion-resistant thrust washer

Technical Field

The utility model relates to a gasket technical field particularly, relates to a corrosion-resistant thrust gasket.

Background

Gaskets (gaskets) are mechanical seals between two objects, typically to prevent pressure, corrosion, and natural thermal expansion and contraction leakage of the tubing between the two objects. Since the machined surface may not be perfect, the irregularities can be filled using shims. The gasket is typically made of a sheet material such as paper, rubber, silicone rubber, metal, cork, felt, neoprene, nitrile rubber, fiberglass, or a plastic polymer (e.g., polytetrafluoroethylene). The gaskets for a particular application may contain asbestos. A shim (washer) is a hole (usually in the middle) in a thin (usually circular) sheet, usually a load thread fastener for distribution. Other uses are as spacers, springs (bellville washers, wave washers), wear pads, pre-displays, lock devices. Rubber gaskets are also used in faucets (valves) to shut off flowing liquids or gases. Rubber or silicon gaskets may also be used to reduce fan vibration.

Currently, gaskets are available on the market, which comprise a gasket body. When the traditional gasket is used, the gasket is corroded by liquid at the sealing position, so that the sealing of a pipe body is affected, the gasket body is directly abutted against the sealing position, and the periphery of the gasket is corroded more easily.

An effective solution to the problems in the related art has not been proposed yet.
