Abstract
The utility model discloses a pipe connection seal structure. The pipe fitting comprises a pipe fitting body, wherein the joint of the pipe fitting body is a bell mouth, and a circle of inward flanges are arranged on the outer edge of the bell mouth. After having increased the turn-ups, when outlet duct and pipe connection, be prior to the turn-ups contact, make the turn-ups take place deformation, when the turn-ups takes place deformation, gradually with the surface in close contact with of outlet duct, when the turn-ups takes place root deformation simultaneously, also can provide one towards the elastic force by sealed face, this elastic force provides the sealing pressure of sealed face, only when the turn-ups deformation arrives with the horn mouth when laminating completely, the horn mouth just can take place deformation, and before this, the turn-ups just can be sealed the laminating completely with the pipe fitting that needs to seal.
Description
Technical Field
The invention relates to the technical field of pipe fittings, in particular to a pipe fitting connection sealing structure.
Background
The air outlet pipe of the compressor on the air conditioner is connected with the condenser pipe, the connection between the compressor and the condenser pipe must ensure reliable sealing, otherwise, the leakage of a refrigerant can be caused, the original connection between the pipe fittings depends on the connection mode of a bell mouth, the end part of one pipe is expanded to be in a bell shape, and then the end part of the other pipe is arranged to be a conical surface matched with the bell mouth. The matching of the conical surface and the trumpet surface can form a sealing surface with a certain distance, which is a common mode for connecting pipe fittings.
In practice, there is a drawback in this connection that the seal between the flare and the conical surface tends to have a gap, and if we increase the pressing force between the conical surface and the flare, the flare is enlarged, resulting in a larger gap, and thus there is a need for improvement.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides a pipe fitting connection sealing structure, which enables the connection sealing performance of the pipe fitting to be more reliable and eliminates the risk of leakage by improving the structure of the bell mouth of the pipe fitting.
In order to solve the technical problems, the invention is solved by the following technical scheme: the pipe fitting connection sealing structure comprises a pipe fitting body, wherein the joint of the pipe fitting body is a horn mouth, and a circle of inward flanges are arranged on the outer edge of the horn mouth. After having increased the turn-ups, when outlet duct and pipe connection, be prior to the turn-ups contact, make the turn-ups take place deformation, when the turn-ups takes place deformation, gradually with the surface in close contact with of outlet duct, when the turn-ups takes place root deformation simultaneously, also can provide one towards the elastic force by sealed face, this elastic force provides the sealing pressure of sealed face, only when the turn-ups deformation arrives with the horn mouth when laminating completely, the horn mouth just can take place deformation, and before this, the turn-ups just can be sealed the laminating completely with the pipe fitting that needs to seal.
In the above technical scheme, preferably, the outer edge of the flanging faces towards the cavity of the pipe fitting body.
In the above technical scheme, preferably, a gap is reserved between the flanging and the inner wall of the bell mouth.
In the above technical scheme, preferably, the diameter of the flange outer edge is smaller than the diameter of the connector of the connecting piece connected with the pipe fitting body.
The invention has the beneficial effects that: after having increased the turn-ups, when outlet duct and pipe connection, be prior to the turn-ups contact, make the turn-ups take place deformation, when the turn-ups takes place deformation, gradually with the surface in close contact with of outlet duct, when the turn-ups takes place root deformation simultaneously, also can provide one towards the elastic force by sealed face, this elastic force provides the sealing pressure of sealed face, only when the turn-ups deformation arrives with the horn mouth when laminating completely, the horn mouth just can take place deformation, and before this, the turn-ups just can be sealed the laminating completely with the pipe fitting that needs to seal.
Drawings
FIG. 1 is a schematic view of the present invention.
Detailed Description
The invention is described in further detail below with reference to the following detailed description and accompanying drawings: referring to fig. 1, the pipe connection sealing structure comprises a pipe body 1, wherein one connection part of the pipe body 1 is a bell mouth 2, the outer edge of the bell mouth is directly larger than the diameter of the pipe body, so that the pipe and other connecting pieces can be conveniently installed in a matching way, meanwhile, the outer edge of the bell mouth 2 is provided with a circle of inward flanges 3, a gap is left between the flanging and the inner wall of the bell mouth, after the flanging is increased, the air outlet pipe is in contact with the pipe fitting prior to the flanging when being connected with the pipe fitting, the flanging deforms, and when the flanging deforms, the flanging is gradually in close contact with the outer surface of the air outlet pipe, when the turn-ups takes place a deformation simultaneously, also can provide one towards the elastic force by sealed face, this elastic force provides the sealing pressure of sealed face, only when the turn-ups warp to with the horn mouth when laminating completely, the horn mouth just can take place deformation, and before this, the turn-ups just can be sealed the laminating completely with the pipe fitting that needs to seal.
According to the actual requirement, different connecting pieces are adapted by changing the angle of the flanging, wherein the compensation performance of the mode that the flanging extends outwards along the cavity facing the pipe fitting body is the best, and the sealing performance is the best.
Meanwhile, in order to ensure absolute sealing performance, the diameter of the outer edge of the flanging is smaller than that of a connector of a connecting piece connected with the pipe fitting body.
During the installation, insert the horn mouth with the connecting piece in, withstand the connecting piece through the outer edge of horn mouth turn-ups, provide extra compensation power for the connection leakproofness of pipe fitting is more reliable, eliminates the risk of leaking.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
