Abstract
The utility model discloses a kind of winged octangonal rings, technical solution used by the utility model be include winged illiciumverum pad body, winged illiciumverum pad body is semi-circular sheet metal, it is equipped with the trapezoidal protrusion of upward first in the middle part of winged illiciumverum pad body and the second downward trapezoidal protrusion, the first trapezoidal protrusion are identical with the second trapezoidal convex shape.The utility model has the beneficial effects that the ladder type annular groove sealing surface sealing effect to flange face is good.
Description
Technical field
The utility model belongs to machinery manufacturing technology field, is related to a kind of novel octagonal shape metal ring pads, can especially increase
Add the sealing performance of metal ring pads and increases the service life of sealing.
Background technology
The raising of pressure medium can make flange and connection bolt deformation, cause into the relative separation between sealing surface, gasket is close
Envelope generates leakage than relative drop.There is a large amount of setting using the sealing of octagonal metal ring pads in existing chemical production device
Standby pipe flange can make flange and connection bolt deformation when the raising of pressure medium, cause into the relative separation between sealing surface,
Gasket seal generates leakage than relative drop.It needs promptly to implement pressure sealing after leaking, gives device production run
Certain puzzlement is caused, such as maintenance replacement flange or adjustment pipeline stress can all cause larger economic loss, in this demand
Lower hope designs a kind of Novel gasket solution problems.
Utility model content
The purpose of this utility model is to provide a kind of winged octangonal rings, the utility model has the beneficial effects that flange face
Ladder type annular groove sealing surface sealing effect it is good.
Technical solution used by the utility model be include winged illiciumverum pad body, winged illiciumverum pad body is semi-circular
Sheet metal, winged illiciumverum pad body middle part are equipped with the trapezoidal protrusion of upward first and the second trapezoidal protrusion downwards, and first is trapezoidal
Protrusion is identical with the second trapezoidal convex shape.
Further, winged illiciumverum pad body is two, and two winged illiciumverum pad bodies are connected to form annular shape.
Description of the drawings
Fig. 1 is utility model diagram；
Fig. 2 is winged octangonal ring stereoscopic schematic diagram.
In figure, 1. winged illiciumverum pad bodies, 2. first trapezoidal protrusions, 3. second trapezoidal protrusions.
Specific implementation mode
The utility model is described in detail With reference to embodiment.
The utility model is as depicted in figs. 1 and 2, including winged illiciumverum pad body 1, and winged illiciumverum pad body 1 is semi-circular
Sheet metal, 1 middle part of winged illiciumverum pad body are equipped with upward first trapezoidal raised 2 and downward second trapezoidal raised 3, the first ladder
Shape protrusion 2 is identical with the second trapezoidal raised 3 shape.
The winged octangonal ring of the utility model is a kind of novel metal ring pads, is mounted on flange face and the height in ladder type annular groove
Laminate seal, cooperation install spirotallic gasket inside and outside the trapezoidal annular groove additional and realize auxiliary seal on two end faces, when spirotallic gasket and ladder
When the inclined-plane seal failure of shape slot, winged octangonal ring can still realize sealing function.When tighten connection bolt when, be compressed axially with
Upper and lower ladder-type trough and interior outer end face note are tight, and winged octangonal ring and metal wound gasket all generate plastic deformation, and it is close to form three ring-types
Band is sealed, sealing is established.When if the raising of pressure medium causes flange and connection bolt to deform, between the inclined-plane for causing dovetail groove
Relative separation, the clamping load on first and third road metal wound gasket so that gasket material is filled up flange sealing surface between it is micro- between
Gap becomes primary seal and pads existing sealing function.
The advantages of winged octangonal ring of the utility model, also resides in the phase between the ladder type annular groove sealing surface for solving flange face
To separation, the problem of gasket seal causes leakage than relative drop, and the flange for making sealing inclined-plane defect occurred still may be used
It has been continuing with.This winged octangonal ring pressure sealing operating expenses can be saved expense about 800,000/year (being counted according to last year), and
The cost and welding procedure expense of the replacement of equipment installation flange can also be saved.
The above is only the better embodiment to the utility model, not makees any form to the utility model
On limitation, every according to the technical essence of the utility model any simple modification made to the above embodiment, equivalent variations
With modification, it is all within the scope of the technical scheme of the utility model.
Claims (2)
