Abstract
The invention discloses a kind of polytetrafluoroethylene (PTFE) rubber blanket.It includes the rubber layer of annular and two layers of carbon fiber layer of rubber layer upper and lower surface is bonded in by binding agent, the outer surface of every layer of carbon fiber layer is compound with pit and raised metal level, the outer surface of two layers of metal level is bonded by binding agent and is compounded with two layers of asbestos layer, and the outer surface of two layers of asbestos layer is bonded by binding agent is compounded with polytetrafluoroethylene floor.After above-mentioned structure, combined strength bination and structure one side are substantially increased by pit and projection, so that larger resilience can be kept between each layer, improve sealing reliability, still further aspect, its combined strength bination is especially high, be not in the problem of coming off, another further aspect, combining layer by layer for different attribute improves corrosion resistance between rubber layer, carbon fiber layer, metal level and asbestos layer, extends service life.
Description
Technical field
The present invention relates to a kind of sealing gasket, specifically a kind of polytetrafluoroethylene (PTFE) rubber cushion.
Background technology
Sealing gasket be in the industries such as oil, chemical industry, machinery, generating in order to realize sealing possessed by one it is essential
Part, although its structure very simple, but there is protrusion in various occasions, existing rubber cushion is tied due to it
Structure design is unreasonable, on the one hand, its resilience is poor, easily causes poorly sealed problem, still further aspect, each layer over time
Molding bonded is generally used between structure, so that easily being come off between each layer, reduces the reliability used, also a side
Face, it is made, in the occasion of some seriously corrodeds, is easily corroded, service life is very short of common material.
The content of the invention
The present invention will connect the polytetrafluoroethylene (PTFE) rubber cushion for providing that a kind of resilience is good, use reliability is high and service life is grown.
In order to solve the above-mentioned technical problem, polytetrafluoroethylene (PTFE) rubber cushion of the invention, including annular rubber layer and pass through
Binding agent is bonded in two layers of carbon fiber layer of rubber layer upper and lower surface, and the outer surface of every layer of carbon fiber layer is compound with recessed
Hole and raised metal level, the outer surface of two layers of metal level is bonded by binding agent is compounded with two layers of asbestos layer, two layers of institute
The outer surface for stating asbestos layer is compounded with polytetrafluoroethylene floor by binding agent bonding.
The thickness of two layers of metal level is 1-3mm.
The cross sectional shape of two layers of metal level is the step structure being engaged with surface to be sealed.
Two layers of asbestos layer and two layers of polytetrafluoroethylene floor are similarly the ladder being engaged with surface to be sealed
Shape structure.
After above-mentioned structure, due to the rubber layer of setting, carbon fiber layer, metal level and asbestos layer, particularly will
The metal level that pit and projection is distributed with is compounded between carbon fiber layer and asbestos layer, is greatly improved from there through pit and projection
The combined strength bination and structure is on the one hand so that larger resilience can be kept between each layer, improve sealing reliability,
Still further aspect, its combined strength bination is especially high, is not in another further aspect the problem of coming off, rubber layer, carbon fiber layer, metal
Combining layer by layer for different attribute improves corrosion resistance between layer and asbestos layer, extends service life.
Brief description of the drawings
Fig. 1 is the cross section structure schematic diagram of polytetrafluoroethylene (PTFE) rubber cushion of the present invention.
Embodiment
With reference to the accompanying drawings and detailed description, the polytetrafluoroethylene (PTFE) rubber cushion of the present invention is described in further detail.
As illustrated, the present invention polytetrafluoroethylene (PTFE) rubber cushion, including annular rubber layer 1 and be bonded in by binding agent
Two layers of carbon fiber layer 2 of rubber layer upper and lower surface, the outer surface of every layer of carbon fiber layer 2 are compound with pit and projection
Metal level 3, the outer surface of two layers of metal level 3 is bonded by binding agent is compounded with two layers of asbestos layer 4, two layers of asbestos layer
4 outer surface is bonded by binding agent and is compounded with polytetrafluoroethylene floor 5, wherein, the thickness of described metal level 3 is 1-3mm, is led to
Crossing the structure design of the metal level of the thickness makes that its bond strength is high and reliability is optimal.
In addition, the cross sectional shape of described two metal layers 3 is the step structure being engaged with surface to be sealed, asbestos
Layer 4 and two layers of polytetrafluoroethylene floor 5 are similarly the step structure being engaged with surface to be sealed, are thus applied to have rank
The flange seal occasion of tread.
