CN202612619U - Fluorine plastic rubber sealing flat washer - Google Patents

Abstract

The utility model discloses a fluorine plastic rubber sealing flat washer and aims to provide a fluorine plastic rubber sealing flat washer which is convenient to manufacture, excellent in corrosion resistance, long in service life and high in sealing performance. The fluorine plastic rubber sealing flat washer comprises an annular flat washer made of rubber, and is characterized in that polytetrafluoroethylene layers are coated on the upper and lower end faces and inner holes of the flat washer. The elasticity and sealing property of the rubber are kept, and the inner holes and the upper and lower end faces of the flat washer are coated by polytetrafluoroethylene materials, so that the washer is high in corrosion resistance and low in manufacturing cost, the defect that the polytetrafluoroethylene lacks of elasticity and cannot be independently made into a sealing ring is overcome, the rubber flat washer and the polytetrafluoroethylene coating are convenient to mount, and the rubber flat washer can be independently used and can be used after being combined with other components.

Description

Fluorine is moulded the rubber seal plain washer

Technical field

The utility model relates to Sealing, relates in particular to fluorine and moulds the rubber seal plain washer.

Background technique

The end face of many pipelines or link needs sealing, and for this reason, the end face between link is equipped with plain washer, and general this plain washer is to process with resilient rubber, is shaped on through hole in the centre of plain washer.But in many occasions, what carry in the pipeline is mordant medium, and like acid or alkaline liquid, and common rubber corrosion resistance is relatively poor.

The content of model utility

The purpose of the utility model provides the fluorine of a kind of easily manufactured, fine corrosion resistance, long service life, good seal performance and moulds the rubber seal plain washer.

In order to reach above-mentioned requirements, the utility model is realized through following technological scheme: it includes the plain washer of processing annular with rubber, it is characterized in that being coated with polytetrafluoroethylene floor at the upper and lower end face and the endoporus of plain washer.

Polytetrafluoroethylmaterial material is a kind of plastics with fine wear resistance and corrosion resistance; Mould the rubber seal plain washer according to the fluorine of such scheme manufacturing, it has kept the elasticity and the sealing of rubber, and both ends of the surface had polytetrafluoroethylmaterial material to coat about endoporus reached; Make this packing ring have good corrosion resistance; Overcome teflon itself and lacked the drawback that elasticity can't be processed seal washer separately, and low cost of manufacture, rubbery flat gasket circle and polytetrafluoroethylcoatings coatings are easy for installation; But the rubbery flat gasket circle uses separately, and use back also capable of being combined.
