Abstract

The invention provides a polytetrafluoroethylene sealing ring comprising a long kidney-shaped polytetrafluoroethylene body. The body comprises a first body with a rectangular cross section and a second body protruding and extending upward from the first body and having a cross section in the shape of an isosceles trapezoid, wherein the sides of the second body and the horizontal direction form an included angle of 45 degrees. A polytetrafluoroethylene sealing material is adopted; polytetrafluoroethylene has extremely excellent chemical stability and an extremely low friction coefficient, in particular filling polytetrafluoroethylene; with the added filling reinforcing material, the physical and mechanical properties are further improved while the original excellent properties are maintained.

Description

Teflin ring

Technical field

The application belongs to technical field of ship transportation, particularly relates to a kind of teflin ring.

Background technology

In macromolecular material, rubber is owing to having good mechanical property and high resilience, elastic modelling quantity The least, therefore it is widely used in anti-vibration article.But on the whole, the machinery of elastomeric material is strong Spending on the low side, wearability is poor, and the frictional resistance produced during motion is big, also has certain in terms of media-resistant Limitation.

On existing freighter, many places need to use rubber part to play the effects such as damping, and rubber used by existing freighter Glue part, causes aliquation to bubble owing to salt fog resistance performance is the best or embrittlement is hardened and aging in surface, is formed Potential safety hazard greatly.

Summary of the invention

It is an object of the invention to provide a kind of teflin ring, with overcome of the prior art not Foot.

For achieving the above object, the present invention provides following technical scheme:

The embodiment of the present application discloses a kind of teflin ring, including the polytetrafluoroethyl-ne in long waist shaped Alkene body, described body has the first noumenon of square-section and upwards protrudes out from described the first noumenon Cross section be the second body of isosceles trapezoid, the side of described second body with the angle of horizontal direction is 45°。

Preferably, in above-mentioned teflin ring, the bottom surface indentation of described the first noumenon.

Preferably, in above-mentioned teflin ring, the end face indentation of described second body.

Preferably, in above-mentioned teflin ring, described the first noumenon is near the one of its bottom surface End is embedded with Magnet.

Preferably, in above-mentioned teflin ring, described second body is near the one of its end face End is embedded with Magnet.

Preferably, in above-mentioned teflin ring, the middle part of described politef body is opened It is provided with the hole that cross section is rounded.

Preferably, in above-mentioned teflin ring, the end face bag of described politef body It is covered with fluorubber epidermis.

Compared with prior art, it is an advantage of the current invention that:

The present invention uses PTFE stuffing materials, politef to have the most superior chemically stable Property and low-down coefficient of friction, particularly filled polytetrafluoroethylene, due to add filler reinforcement material, Making it on the basis of keeping original premium properties, physical and mechanical properties is further enhanced so that produce Product hot strength the most significantly exceedes the index request of routine >=10Mpa and reaches about 13.4Mpa.

It addition, the teflin ring of the present invention also has chemicals-resistant, oil resistant and resistant to elevated temperatures excellent Point.

Accompanying drawing explanation

In order to be illustrated more clearly that the embodiment of the present application or technical scheme of the prior art, below will be to reality Execute the required accompanying drawing used in example or description of the prior art to be briefly described, it should be apparent that below, Accompanying drawing in description is only some embodiments described in the application, for those of ordinary skill in the art From the point of view of, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 show the structure top view of teflin ring in the specific embodiment of the invention；

Fig. 2 show the sectional view of teflin ring in the specific embodiment of the invention.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out Detailed description, it is clear that described embodiment is only a part of embodiment of the present invention rather than complete The embodiment in portion.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creation Property work on the premise of the every other embodiment that obtained, broadly fall into the scope of protection of the invention.

Shown in ginseng Fig. 1 and Fig. 2, teflin ring includes the politef body 1 in long waist shaped, The first noumenon 11 that described body has square-section and the cross section upwards protruded out from described the first noumenon The second body 12 in isosceles trapezoid, the side 13 of described second body is 45 ° with the angle of horizontal direction

In this technical scheme, body uses polytetrafluoroethylmaterial material, can be greatly improved its mechanical performance And frictional behaviour.

Further, the bottom surface indentation of the first noumenon.The end face indentation of the second body.

In this technical scheme, by serrated-surface, can improve teflin ring and hatchcover, Sealing between teflin ring and draw-in groove.

Further, the first noumenon is embedded with Magnet near one end of its bottom surface.Second body pushes up near it The one end in face is embedded with Magnet.

In this technical scheme, by arranging Magnet in teflin ring, politef is close Seal can directly adsorb on hatchcover or draw-in groove, improves and installs convenience.

The middle part of described politef body offers the hole that cross section is rounded.

In this technical scheme, politef can be improved by hole in the middle part of politef body The elastic space of sealing ring in the vertical direction.

Further, the end face of politef body is coated with fluorubber epidermis.

It should be noted that in this article, the relational terms of such as first and second or the like is used merely to One entity or operation are separated with another entity or operating space, and not necessarily requires or imply Relation or the order of any this reality is there is between these entities or operation.And, term " includes ", " comprise " or its any other variant is intended to comprising of nonexcludability, so that include that one is The process of row key element, method, article or equipment not only include those key elements, but also include the brightest Other key elements really listed, or also include intrinsic for this process, method, article or equipment Key element.In the case of there is no more restriction, statement " including ...
