Abstract
The utility model is related to gasket seal technical fields, in particular a kind of self-tightening sealing gasket, include triangle gasket and flange body, flange body offers through-hole, the side wall of flange body is fixedly connected with fixed ring, the basal plane of fixed ring offers, and the lower circumference of flange body is equipped with vee gutter, and the inner wall of triangle gasket, which is equipped with, to be faced directly.The diameter in free state is more bigger than the diameter of seal groove by triangle gasket for the utility model, and when tightening end cap with connector, triangle gasket is radially compressed, and is fastened with upper-lower seal slot and generates pretightening unit sealing load.When container pressure rises, triangle gasket is bent outwardly, its two conical surfaces are more adjacent to the conical surface of seal groove, therefore pressure is higher, and the effect of radial seal energized by internal pressure is better.Pretightning force can be reduced, and can be used in the operating mode that larger pressure and temperature fluctuates.Connector refers to high-pressure bolt or yoke configurations etc..
Description
Technical field
The utility model is related to gasket seal technical field more particularly to a kind of self-tightening sealing gaskets.
Background technology
Flange gasket is used in pipe flange connection, the sealing element between two panels flange, medium, and pressure and temperature is direct
Influence the type selecting of flange gasket.Octangonal ring derives from the U.S. earliest, uses field of boilers for the first time in the 1920s, is used for people
The sealing of port lid, autoclave and other containers especially receives attention in Petroleum Production and petroleum refining industry later, as steam is dynamic
The temperature and pressure of power apparatus increases, and the purposes of the gasket is with regard to more and more extensive.It is usually applied to high pressure high temperature vapor, gas,
The pipe flange of solvent, tower slot, pressure vessel, high velocity engagement face, high temperature high pressure valve, lid.Well head dress in industrial gas oil
It sets and the sealing on production tree.We improve a kind of self-tightening sealing gasket.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and a kind of self-tightening sealing pad proposed
Piece.
To achieve the goals above, the utility model uses following technical solution：
A kind of self-tightening sealing gasket, includes triangle gasket and flange body, and the flange body offers through-hole, the flange
The side wall of body is fixedly connected with fixed ring, and the basal plane of the fixed ring offers, and the lower circumference of the flange body is equipped with three
Angle-shaped groove, the inner wall of the triangle gasket, which is equipped with, to be faced directly.
Preferably, the triangle gasket and flange body are circle, and preferably high-precision is processed.
Preferably, triangle gasket diameter in free state is more bigger than the diameter of seal groove.
Preferably, the inner wall faced directly positioned at vee gutter.
Preferably, the triangle gasket is symmetrically connected to two flange bodies.
Preferably, the preferably high-precision of facing directly is processed.
Compared with prior art, the utility model has the beneficial effects that：
1, by triangle gasket 1, in free state, diameter is more bigger than the diameter of seal groove, when with connector tighten end
Gai Shi, triangle gasket 1 are radially compressed, and are fastened with upper-lower seal slot and are generated pretightening unit sealing load.When container pressure rises,
Triangle gasket 1 is bent outwardly, its two conical surfaces are more adjacent to the conical surface of seal groove, therefore pressure is higher, radial seal energized by internal pressure
Effect is better.Pretightning force can be reduced, and can be used in the operating mode that larger pressure and temperature fluctuates.Connector refers to high pressure spiral shell
Bolt or yoke configurations etc..
2, it is processed, is easily worked, leakproofness is preferable by facing preferably high-precision directly.
In the utility model, it is not directed to part in the device and is the same as those in the prior art or can be used the prior art and be subject to reality
Existing, the utility model is easily worked, and leakproofness is preferable.
Description of the drawings
Fig. 1 be the utility model proposes a kind of self-tightening sealing gasket whole structural schematic diagram；
Fig. 2 be the utility model proposes a kind of self-tightening sealing gasket part structural schematic diagram.
In figure：1 triangle gasket, 2 flange bodies, 3 through-holes, 4 fixed rings, 5 through-holes, 6 vee gutters, 7 are faced directly.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
In the description of the present invention, it should be understood that term "upper", "lower", "front", "rear", "left", "right",
The orientation or positional relationship of the instructions such as "top", "bottom", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, and is only
The utility model and simplifying describes for ease of description, do not indicate or imply the indicated device or element must have it is specific
Orientation, with specific azimuth configuration and operation, therefore should not be understood as limiting the present invention.
Fig. 1-2 is please referred to, a kind of self-tightening sealing gasket includes triangle gasket 1 and flange body 2, and the flange body 2 opens up
There are through-hole 3, the side wall of the flange body 2 to be fixedly connected with fixed ring 4, the basal plane of the fixed ring 4 offers 5, the method
The lower circumference of blue body 2 is equipped with vee gutter 6, and the inner wall of the triangle gasket 1, which is equipped with, faces 7 directly.
The triangle gasket 1 and flange body 2 are circle, and preferably high-precision is processed.
The diameter in free state of triangle gasket 1 is more bigger than the diameter of seal groove.
It is described to face 7 inner walls for being located at vee gutter 6 directly.
The triangle gasket 1 is symmetrically connected to two flange bodies 2.
The 7 preferably high-precisions of facing directly are processed.
The working process of the utility model is as follows：In practical work process by triangle gasket 1 in free state diameter
More bigger than the diameter of seal groove, when tightening end cap with connector, triangle gasket 1 is radially compressed, with upper-lower seal slot
It fastens and generates pretightening unit sealing load.When container pressure rises, triangle gasket 1 is bent outwardly, its two conical surfaces are more adjacent to close
The conical surface of sealing groove, therefore pressure is higher, the effect of radial seal energized by internal pressure is better.Pretightning force can be reduced, and can be in larger pressure
It is used in power and the operating mode of temperature fluctuation.Connector refers to high-pressure bolt or yoke configurations etc..
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is appreciated that can these embodiments be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaiied
