Description

Self-adhesive gasket

Technical Field

The application relates to the technical field of gaskets, in particular to a self-adhesive gasket.

Background

Gaskets (gaskets) are mechanical seals between two objects, and are commonly used to prevent pressure, corrosion, and natural thermal expansion and contraction leakage of 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 grommet (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. Typically the outside diameter of the gasket is about twice the inside diameter.

When using, the existing gasket cannot adjust the spacing distance between an object and the object, so that the distance between the object and the object is fixed, when the thickness of the gasket is too large, the situation of large gap is easy to occur, and because the gasket is formed by pressing, the corners of the front and back surfaces of the gasket and the middle position are not in the same plane, so that the gasket is too over in the contact of an outer ring in the using process.
