Abstract
A kind of octagonal metal ring gasket, belong to sealing element technical field, it includes ontology, the ontology upper and lower ends face is machined with concentric gear ring, the gear ring section is semicircle, it is arranged in order and is covered with entire upper and lower end face, the design of this flank of tooth makes to become line contact from traditional face contact between gasket and flange groove, substantially increases its leakproofness.The center of described body side surface is machined with groove, rubber ring is cased on groove, when gasket is positioned in flange groove, rubber ring is adjacent to dovetail groove side, due to the elastic property of rubber ring, complex working condition lower gasket is can effectively prevent to loosen or deform, it is also not high to the size of flange groove and surface roughness requirements in addition.
Description
Technical field
The utility model is related to a kind of gasket seal, more particularly to a kind of octagonal metal ring gasket.
Background technology
Metal ring pads derive from the U.S. earliest, field of boilers are used for the first time in the 1920s, for manhole cover, high pressure
The sealing of kettle and other containers is especially taken seriously in Petroleum Production and petroleum refining industry, later with Steam Power Equipment
Temperature and pressure increases, and the purposes of metal ring pads is with regard to more and more extensive.
Metal annular gasket is divided into octagonal and oval two kinds of structures, octagonal ring pads and flange groove phase by cross sectional shape
Match, is mainly shown as that face contacts.Compared with oval ring pads, although being not easy to reach closely sealed with flange groove, it can reuse,
And it because section is made of straight line, is easily worked.Vesica piscis gasket is line contact in flange groove, and leakproofness is preferable, but is added
Work required precision is high, thus increases manufacturing cost, while oval ring pads cannot be reused.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, adapt to reality and need, and design is a kind of easy to install, close
The good octagonal metal ring gasket of envelope property.
In order to realize that the utility model aim, the utility model use following technical solution：
A kind of octagonal metal ring gasket, belongs to sealing element technical field, it includes ontology, the ontology upper and lower ends face
It is machined with concentric gear ring, the gear ring section is semicircle, is arranged in order and is covered with entire upper and lower end face, the design of this flank of tooth
Make to become line contact from traditional face contact between gasket and flange groove, substantially increases its leakproofness.Described body side surface
Center is machined with groove, and rubber ring is cased on groove, when gasket is positioned in flange groove, rubber ring and dovetail groove side
It is adjacent to, gasket loosening is can effectively prevent, due to the elastic property of rubber ring, so the size and surface roughness to flange groove are wanted
Ask not high.
Preferably, the ontology upper and lower ends face is the flank of tooth, and multilayer linear sealing is formed when gasket is bonded with flange groove.
Preferably, described body side surface is machined with groove, and groove is cased with rubber ring.
The beneficial effects of the utility model are：Contact surface is the design of the flank of tooth, and gasket is made to be formed when flange groove is bonded
Multilayer linear sealing, sealing effect are significantly stronger than the face contact sealing of traditional octagonal metal ring pads.Upper rubber is covered in gasket side
Cushion rubber solves the production cost that the fine fit of conventional spacers flange package size is brought, thus to the size of flange groove and
Surface roughness requirements are not high.
Description of the drawings
Fig. 1 is sectional view at the A of gasket；
The vertical view of Fig. 2 gaskets；
1 semi-circular teeth, 2 grooves, 3 rubber rings, 4 gear rings in figure.
Specific implementation mode
The utility model is described in detail below in conjunction with the accompanying drawings：
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and specifically
The technical solution of the utility model embodiment is clearly and completely described in embodiment.Obviously, described embodiment
It is a part of the embodiment of the utility model, rather than whole embodiments.Based on described the embodiments of the present invention, originally
The every other embodiment that field technology personnel are obtained shall fall within the protection scope of the present invention.
Fig. 2 referring to Fig.1, the utility model are a kind of octagonal metal ring pads, it includes common octagonal pad body, described
Ontology upper and lower ends face is machined with concentric gear ring（4）, it is arranged in order, is covered with entire end face, the gear ring（4）Section be one
Arrange semi-circular teeth（1）, the semi-circular teeth（1）It is highly consistent, such gasket upper and lower ends face just becomes the flank of tooth by plane.
The side of the ontology is equipped with groove（2）, the groove（2）It is located at the centre position of described body side surface, the groove（2）It is interior
It is cased with elastic rubber ring（3）.When being tightened by bolt in gasket implantation flange slot, the gasket flank of tooth is adjacent to flange face, each
Semi-circular teeth（1）It is all bonded with flange, forms multilayer linear sealing, due to there is multilayer linear sealing, so ought wherein some is semicircle
Tooth（1）It cannot be bonded completely because flange face precision is not high, other teeth also can overcome the disadvantages that form sealing.The rubber of described body side surface
Circle（3）Closely surround the groove（2）It is interior, rubber ring after installation（3）It is adjacent to dovetail groove side, can effectively prevent gasket pine
It is dynamic.Due to rubber ring（3）With elasticity, so can also be installed into when flange groove size is unable to fine fit, at work
When encountering internal pressure unevenness, rubber ring（3）Also can effectively prevent gasket deformation causes leakproofness to reduce.
In conclusion this practicability is novel by having plane machining at the flank of tooth end face of common octagon ring pads, significantly
Improve its leakproofness.The design of upper rubber ring is covered in side, so that gasket is not easy to loosen under complex working condition and is deformed, to flange
The size and surface roughness requirements of slot be not also high.
Above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, those of ordinary skill in the art couple
Other modifications or equivalent replacement that the technical solution of the utility model is made, without departing from technical solutions of the utility model
Spirit and scope should all cover in the right of the utility model.
