It can be the connection inside two elements.For the ordinary skill in the art, on being understood by concrete condition
State concrete meaning of the term in the invention.
Below with reference to embodiment come the present invention will be described in detail create.
A kind of tunnel pipe for escaping connection sealing of the anti-disengagement of high sealing, as shown in Figures 1 to 3, including sealing ring body, it should
Sealing ring body includes cooperation section 1 and fixed section 2, is equipped with the auxiliary section 3 being bonded with affixed side inner wall of the pipe in cooperation section outer wall；
The cooperation section outer end face is equipped with compression groove 4, forms lip 5 in cooperation section outer rim；The fixed section inner wall is equipped with metallic framework
6, metallic framework inner wall is equipped with several tooth engageds 7, and the oblique cooperation section side of each tooth engaged is obliquely installed；The lip is equipped with
Several gap 8, each gap are uniformly arranged centered on sealing ring body central axes；The gap is U-shaped, and gap depth is lip
The half of width.
General " expanding " processing in the connecting pin of fixed side ducts, and socket joint side ducts connecting pin is generally " undergauge " processing,
That is, the flaring that socket joint side ducts can be facilitated to be inserted into is processed in affixed side conduit connection end, connection provided by the invention
Sealing is exactly arranged in the flaring.
When being laid with tunnel pipe for escaping, need to dock the operation of two side ducts are as follows:
In " flaring " of affixed side conduit connection end that first this connection sealing push-in has been laid, using auxiliary section and
The fitting of affixed side inner wall of the pipe is realized preliminary fixed.Later, affixed side conduit connection end is inserted into socket joint side ducts connecting pin,
It is pushed into this connection sealing, when metallic framework is crossed in socket joint side ducts connecting pin to be inserted into inside lip, outside pipeline
Wall is contacted with lip inner wall.
Above-mentioned lip is usually an integral molding structure with ontology, also, lip inner wall is set as cone structure (outside auxiliary section
The small one end of diameter is on ontology the side for having lip), above-mentioned compression groove is the V-type annular groove or U-shaped annular groove of opening outwardly.Socket joint
The lip of side ducts and sealing ring body gradually realizes tight fit, and during lip is by spreading, metallic framework side can be taken up,
To socket joint side pipe pipeline outer wall close to being eventually engaged pipeline outer wall by the tooth engaged of metallic framework inner wall, realize reliable
It connects and fixed.
It should be pointed out that being tilted due to setting oblique cooperation section side for each tooth engaged, held when tooth engaged is engaged in
When inserting side pipe pipeline outer wall, each tooth engaged plays the role of to guarantee to connect to greatest extent on similar fish hook " hangnail "
Reliability, even if by biggish impact force at two pipeline docking, do not easily lead to yet pipeline disengaging.
In general, above-mentioned gap is provided with the road 5-8.Gap width is 1-2mm.By designed gap structure, effectively
The versatility of this connection sealing is improved, after the insertion connection sealing of socket joint side ducts, gap can be by appropriate spreading, so that pipeline
Socket joint docking operation is more smooth, can greatly improve the efficiency of pipeline spigot-and-socket operation.It should be noted that gap depth is commonly designed
For the half of lip width, lip failure is effectively avoided, gap is not unconfined by the gap of spreading, by lip
The constraint of internal diameter both ensure that and versatility and be easy to grafting, simultaneously, it is ensured that the stability and sealing of two side ducts connections
Property, service performance is not affected.
The auxiliary section is cone structure, and outer diameter small one end in auxiliary section is on ontology the side for having lip, is convenient for
This sealing of installation settings, also, when progress two side ducts docking, after lip spreading, it can promote outside auxiliary section to a certain extent
Diameter increases, and is preferably bonded tube wall, and such structure design more meets actual loading feature.
Above-mentioned metallic framework includes the 6-10 segmental arc 9 being uniformly arranged centered on ontology central axes, and each segmental arc is equal
It embeds on the body.Ontology generallys use rubber material, using sulfuration process by ontology in conjunction with each segmental arc, will not occur
Situations such as falling off, stable structure are reliable.
Wherein, each tooth engaged is identical as each arc segment length, and what is be spaced on each segmental arc is equipped with number
Arrange tooth engaged.In general, the tooth engaged is arranged equipped with 3-5, it is equidistantly spaced from the axial direction of sealing ring body.
The invention structure is simple, design rationally, using sealing ring body outer wall auxiliary section can to it is firm with
The cooperation of affixed side inner wall of the pipe, the lip of inner wall are influenced after by the insertion of socket joint side ducts, can generate deformation, " tension " each gold
Belong to skeleton to shrink to socket joint side ducts, until each tooth engaged penetrates pipeline outer wall, be equivalent to " stinging " and lived socket joint side ducts, it is ensured that
The reliability of two side ducts connection, also, there is splendid sealing effect.
The foregoing is merely the preferred embodiments of the invention, are not intended to limit the invention creation, all at this
Within the spirit and principle of innovation and creation, any modification, equivalent replacement, improvement and so on should be included in the invention
Protection scope within.
