Description
Technical Field
The utility model relates to a sealing device correlation field particularly, relates to a bellows seal circle.
Background
In the connection of corrugated pipes, usually, a spigot of one corrugated pipe is inserted into a socket of another corrugated pipe to realize connection, the aperture of the spigot is smaller than that of the socket, at present, the sealing of the spigot and the socket is usually provided with a sealing rubber ring at the trough of the spigot, the structural assembly is very difficult, special auxiliary tools are often needed, time and labor are wasted, and the sealing effect is poor.
An effective solution to the problems in the related art has not been proposed yet.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned technical problem among the correlation technique, the utility model provides a bellows seal ring can solve above-mentioned problem.
In order to achieve the technical purpose, the technical scheme of the utility model is realized as follows:
the utility model provides a bellows seal circle, the bellows includes crest segment and trough segment that a plurality of intervals set up in turn, bellows seal circle be used for set up in it is right on the crest segment the bellows seals, bellows seal circle includes the annular seal main part, annular seal main part inboard be equipped with the seal groove that the crest segment matches.
In the bellows sealing washer that this application provided, the seal groove with the crest segment is transition fit or interference fit.
In the bellows seal circle that this application provided, the material of annular seal main part is for meeting water inflation rubber.
In the bellows seal circle that this application provided, the degree of depth of seal groove equals the top of crest segment is to the distance of trough segment bottom.
In the bellows sealing ring that this application provided, there is a sealing strip at least to extend along keeping away from in the annular seal main part outside the direction of seal groove.
In the bellows sealing circle that this application provided, the quantity of sealing strip is three, and is located the centre the length of sealing strip is greater than and is located both sides the length of sealing strip.
The utility model has the advantages that: through annular seal main part inboard set up with the seal groove that the crest section matches makes bellows sealing washer be convenient for set up in on the crest section of bellows, be convenient for install, also reduce the destruction to the sealing washer in the installation, also guaranteed simultaneously right bellows seal's effect.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required to be used in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
FIG. 1 is a side view of a bellows seal ring;
fig. 2 is a schematic cross-sectional view of one side of the bellows seal ring.
In the figure: 1. annular seal main part, 2 seal groove, 3 the sealing strip.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.
As shown in fig. 1-2, according to the embodiment of the utility model provides a bellows seal ring, the bellows includes crest segment and trough segment that a plurality of intervals set up in turn, bellows seal ring be used for set up in right on the crest segment the bellows seals, bellows seal ring includes annular seal main part 1, 1 inboard sides of annular seal main part be equipped with the seal groove 2 that the crest segment matches.
It can be understood that, at present, the sealed trough department at the socket department of socket usually sets up the sealing rubber circle with the socket of bellmouth of bellows, and this kind of structural assembly is very difficult, often needs to adopt special appurtenance, wastes time and energy to sealed effect is also relatively poor, in this embodiment, through 1 inboard settings of annular seal main part with crest section matched with seal groove 2, make bellows sealing ring be convenient for set up in on the crest section of bellows, the installation of being convenient for also reduces the destruction to the sealing washer in the installation, has also guaranteed simultaneously rightly the sealed effect of bellows.
In one embodiment, the sealing groove 2 and the peak section are in transition fit or interference fit; it can be understood that the sealing groove 2 and the wave crest section are in transition fit or interference fit, so that the corrugated pipe sealing ring is tightly connected with the corrugated pipe, and the sealing performance is better.
In an embodiment, the material of annular seal main part 1 is for meeting water inflation rubber, and it can be understood that through with the material of annular seal main part 1 sets up to meeting water inflation rubber, makes bellows seal is after assembling, realizes filling the abundant in clearance through meeting water inflation, further improves bellows seal's sealing performance.
In an embodiment, the depth of the sealing groove 2 is equal to the distance from the top end of the peak section to the bottom end of the valley section, and it can be understood that the depth of the sealing groove 2 is set to be equal to the distance from the top end of the peak section to the bottom end of the valley section, so that the sealing groove 2 completely covers the peak section of the corrugated pipe, is in full contact with the peak section of the corrugated pipe, and can be matched with the valley section of the corrugated pipe to enhance the sealing effect.
In an embodiment, the annular sealing main body 1 outside is along keeping away from the direction of seal groove 2 extends at least and has a sealing strip 3, and it can be understood that, in concrete use, the laminating of the crest section of bellows sealing washer inboard and a bellows socket, the bellmouth contact of bellows sealing washer outside and another bellows, for guaranteeing the bellows sealing washer outside fully contacts with the bellmouth of another bellows 1 outside is along keeping away from seal groove 2's direction extends a sealing strip 3 at least, through the setting of sealing strip 3, realization that can be fine the bellows sealing washer fully contacts with the bellmouth of another bellows. Specifically, the quantity of sealing strip 3 is three, and is located the centre sealing strip 3's length is greater than and is located both sides sealing strip 3's length, it is further, three sealing strip 3 is "mountain" style of calligraphy setting to can combine the further sealing performance that strengthens of structure of meeting water inflation rubber.
In conclusion, the sealing groove 2 matched with the wave crest section is arranged on the inner side of the annular sealing main body 1, so that the corrugated pipe sealing ring is convenient to arrange on the wave crest section of the corrugated pipe, is convenient to install, reduces damage to the sealing ring in the installation process, and simultaneously ensures the sealing effect of the corrugated pipe.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
