Abstract
The utility model relates to a tooth type gasket, including being annular gasket body, the profile of tooth circle that the concentric circles was arranged, its characterized in that are all seted up to the sealed face in both sides about this gasket body: be equipped with in one of them side of the upper and lower both sides of gasket body and encircle the V -arrangement groove of the profile of tooth circle that the concentric circles was arranged. Compared with the prior art, the utility model has the advantages of setting both sides about the gasket body are the profile of tooth circle V -arrangement groove at least on one side that the concentric circles was arranged, the gasket body too big effect of extrusion deformation volume under high -pressure state that prevents has, a security protection that the gasket is by conquassation or damage is provided, the potential safety hazard because of seal failure brings has greatly been reduced, and the angle range in V -arrangement groove is 70~90, can guarantee that the gasket body is in in the best elastic range, simultaneously not by the conquassation, thereby showing and improving the gasket seal life cycle, and adaptation operating mode environment must change the ability.
Description
Technical field
This utility model is related to a kind of pad, more particularly to a kind of dentiform gasket.
Background technology
Grooved metal gasket refers to that general accurate lathe processes groove concentrically in two faces of metal rustless steel flat shim,
According to different media, may be selected soft graphite, PTFE, without asbestos board or some other soft metal, be pasted onto two faces of pad,
Also can directly use without sealant, and good sealing effectiveness can be reached, be particularly well-suited to high temperature, high pressure etc. and easily cause reality
The occasion of effect.
Metal serrated gasket can be divided into band outer shroud metal serrated gasket, band DNA releaxed circular DNA grooved metal gasket, fundamental form grooved metal gasket.Gold
The body of category makes pad have enough intensity, can be used in the higher occasion of pressure；Concentric profile of tooth circle can provide effectively close
Seal, as needed the soft graphite of surface re-binding, tetrafluoro, the material of Muscovitum etc., to improve sealing effectiveness.If in high pressure occasion
If the amount of compression of middle grooved metal gasket is too big, easily flange surface is caused damage.
The content of the invention
Technical problem to be solved in the utility model is that a kind of extruding time-varying is provided for above-mentioned state of the art
The little dentiform gasket of shape amount.
This utility model solve the technical scheme that adopted of above-mentioned technical problem for：The dentiform gasket, including pad annular in shape
Piece body, the upper and lower both sides sealing face of the shim body offers concentric profile of tooth circle, it is characterised in that：In the shim body
The V-shaped groove of the profile of tooth circle of the concentric arrays is provided around on the side at least within of lower both sides.
Further, the angle α scope of the V-shaped groove is 70 °～90 °.Due to the state that grooved metal gasket is acted in high pressure
Under, can jointly play anti-extrusion effect, and identical pressure strip with the concentric profile of tooth circle positioned at sealing surface mid portion
Under part, the amount of compression of dentiform gasket diminishes and can effectively reduce the loss caused to flange surface.Its angle is preferably 70 °～90 °, should
Angle can be effectively ensured with preferably anti-extrusion ability.
Further, the gap d size between each profile of tooth circle is between 0.1mm～0.2mm.Between between each profile of tooth circle
Gap can guarantee that grooved metal gasket in the state of high pressure effect, to both sides relative distension or gentry can be drawn, to form counter pressure
Backup seal line, there is provided extra sealability, formed two grades of compressive sealed protection mechanisms, so substantially increase pad
Service life.
Preferably, the teeth groove angle β of the profile of tooth circle is 90 °.
Compared with prior art, the utility model has the advantage of being arranged on the upper and lower both sides of shim body in concentric arrays
Profile of tooth circle at least one side V-shaped groove, with preventing the shim body excessive effect of extrusion deformation degree in a high voltage state, there is provided
Pad is not protected by the safety of conquassation or damage, greatly reduces the potential safety hazard brought because of seal failure, and V-shaped groove
Angular range is 70 °～90 °, ensure that shim body in optimal elastic range, while not by conquassation, so as to notable
Gasket seal usage cycles are improve, and adaptation condition environment must change to obtain ability.
Description of the drawings
Fig. 1 is the structural representation of this utility model embodiment.
Specific embodiment
This utility model is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in figure 1, this dentiform gasket includes shim body 1 annular in shape, the shim body is opened in both sides sealing face about 1
Be provided with the profile of tooth circle 2 of concentric arrays, the angle β of the profile of tooth circle 2 both can to have inclined towards pressure source direction for 90 ° or
Bend alignment, or arrangement is erect, is to prevent the extrusion deformation degree mistake in a high voltage state of shim body 1 in the present embodiment
Greatly, one side of the profile of tooth circle 2 of concentric arrays is provided with the V-shaped groove 3 that angle α is 90 °, and this V-shaped groove 3 can ensure that sealing profile of tooth circle 2
The seal compression and rebound performance of power equal enough are being obtained, metal serrated gasket is being solved long-standing because loading force is excessive
The easy conquassation of sealing profile of tooth circle 2 damages the problem for causing seal failure, additionally, and the gap d size between each profile of tooth circle 2 be
0.1mm, the gap can guarantee that grooved metal gasket in the state of high pressure effect, to both sides relative distension or gentry can be drawn, with shape
Into the backup seal line of counter pressure, there is provided extra sealability, two grades of compressive sealed protection mechanisms are formed, so carried significantly
The high service life of pad.
