Abstract
The invention discloses pipe fittings to connect sealing structure.Including pipe fitting ontology, pipe fitting ontology junction is horn mouth, and the horn mouth outer is provided with the inside flange of a circle.After increasing flange, when escape pipe is connect with pipe fitting, it is contacted prior to flange, so that deformation occurs for flange, flange is when deformation occurs, gradually it is in close contact with the outer surface of escape pipe, when root deformation occurs for flange simultaneously, also one can be provided towards by the elastic force of sealing surface, this elastic force provides the sealed pressure of sealing surface, and only when flange, which is deflected into, to be bonded completely with horn mouth, loudspeaker eloquence can deformation occurs, and before this, flange can and need the pipe fitting sealed that fitting is fully sealed.
Description
Technical field
The present invention relates to pipe fitting technical field, especially pipe fittings to connect sealing structure.
Background technique
Compressor escape pipe on air-conditioning is connected with condenser pipe, and the connection between compressor and condenser pipe must assure that sealing
Reliably, it not so will cause the leakage of refrigerant, the connection between these original pipe fittings is all to rely on bell-mouthed connection type, will
Wherein the end of a root canal expands, and in horn-like, another root canal end is then arranged to the conical surface to match with horn mouth.Cone
The cooperation in face and loudspeaker face can form the sealing surface of a distance, be the usual way connected between pipe fitting.
In actual use, this connection type is exactly that the sealing between horn mouth and the conical surface is often deposited there are a defect
In gap, if we increase the pressing force between the conical surface and horn mouth, horn mouth can be stretched, and cause gap bigger, because
It is necessary to be improved for this.
Summary of the invention
The present invention aiming at the shortcomings in the prior art, provides pipe fitting connection sealing structure, by improving pipe fitting loudspeaker
The structure of mouth, so that the connection sealing of pipe fitting is relatively reliable, the risk stopped a leak.
In order to solve the above technical problems, the present invention is addressed by following technical proposals: pipe fitting connects sealing structure, packet
Pipe fitting ontology is included, pipe fitting ontology junction is horn mouth, and the horn mouth outer is provided with the inside flange of a circle.Increase
After flange, when escape pipe is connect with pipe fitting, contacted prior to flange, so that deformation occurs flange, flange is when deformation occurs,
It is gradually in close contact with the outer surface of escape pipe, while when flange generation root deformation, can also provide one towards by sealing surface
Elastic force, this elastic force provide the sealed pressure of sealing surface, only when flange, which is deflected into, to be bonded completely with horn mouth, loudspeaker
Eloquence can deformation occurs, and before this, flange can and need the pipe fitting sealed that fitting is fully sealed.
In above-mentioned technical proposal, it is preferred that the flange outer is towards in the cavity of the pipe fitting ontology.
In above-mentioned technical proposal, it is preferred that there are gaps between the flange and the horn mouth inner wall.
In above-mentioned technical proposal, it is preferred that the diameter of the flange outer is less than the connection connecting with the pipe fitting ontology
The diameter of the connector of part.
The beneficial effects of the present invention are: when escape pipe is connect with pipe fitting, contacted prior to flange after increasing flange,
So that deformation occurs for flange, flange is gradually in close contact, while root shape occurs for flange when deformation occurs with the outer surface of escape pipe
When change, also providing one, this elastic force provides the sealed pressure of sealing surface towards by the elastic force of sealing surface, only when
Flange is deflected into when being bonded completely with horn mouth, and loudspeaker eloquence can deformation occurs, and before this, flange can with need to seal
Pipe fitting fitting is fully sealed.
Detailed description of the invention
Fig. 1 is schematic diagram of the present invention.
Specific embodiment
Present invention is further described in detail with specific embodiment with reference to the accompanying drawing: referring to Fig. 1, pipe fitting connection is close
One junction of seal structure, including pipe fitting ontology 1, the pipe fitting ontology 1 is horn mouth 2, and horn mouth outer is directly greater than pipe
The diameter of part ontology, convenient for being coupled for pipe fitting and other connectors, meanwhile, 2 outer of horn mouth be provided with a circle to
Interior flange 3, there are gaps between the flange and horn mouth inner wall, excellent when escape pipe is connect with pipe fitting after increasing flange
It is contacted prior to flange, so that deformation occurs for flange, flange is gradually in close contact, together when deformation occurs with the outer surface of escape pipe
When flange occur root deformation when, can also provide one towards by the elastic force of sealing surface, this elastic force provides sealing surface
Sealed pressure, only when flange, which is deflected into, to be bonded completely with horn mouth, loudspeaker eloquence can deformation occurs, and before this, it turns over
Side can and need the pipe fitting sealed that fitting is fully sealed.
According to actual needs, different connectors is adapted to by changing the angle of flange, wherein by flange outer direction
The intracorporal this mode of the chamber of pipe fitting ontology it is compensatory preferably, leakproofness is best.
Meanwhile to guarantee absolute leakproofness, the diameter of the flange outer is less than the company connecting with the pipe fitting ontology
The diameter of the connector of fitting.
When installation, connector is inserted into horn mouth, connector is withstood by horn mouth flange outer, additional benefit is provided
Power is repaid, so that the connection sealing of pipe fitting is relatively reliable, the risk stopped a leak.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although with reference to the foregoing embodiments
Invention is explained in detail, those skilled in the art should understand that: it still can be to aforementioned each implementation
Technical solution documented by example is modified or equivalent replacement of some of the technical features；And these modification or
Replacement, the spirit and scope for technical solution of various embodiments of the present invention that it does not separate the essence of the corresponding technical solution.
