Abstract

The utility model discloses a pipe joint, comprising a metallic pipe joint, which is characterized in that an anti-pollution heat insulation plastic layer is arranged on internal hole of the pipe body of the metallic pipe joint; both ends of the anti-pollution heat insulation plastic layer are clipped on end face of internal holes of pipe bodies. Compared with the prior art, the utility model has the advantages that the thermal energy is not easy to dissipate when transmitting hot water, and has good heat preservation efficiency.

Description

A kind of pipe joint

The utility model relates to a kind of water heating fittings, particularly a kind of pipe joint.

The existing pipe joint that is used to engage water pipe all is produced with metal; because the heat-conducting property of metal is splendid; thermal insulation property is poor; no matter what carry is hot water or cold water; the inside and outside energy of pipe joint can both exchange mutually by the very big outer surface of surface area of metallic pipe coupling and pipe joint; the interior hot water energy of pipe is scattered and disappeared and temperature decline, and cold water rises because of having absorbed the external heat temperature, thereby has influenced the protection of the water temperature of being transmitted.

When goal of the invention of the present utility model was to provide a kind of transmission hot water, heat was difficult for scattering and disappearing, and when carrying cold water, was difficult for drawing external heat, the pipe joint with insulation effect.

The utility model is achieved in that and comprises that a metallic pipe coupling, its specialization are that the pipe shaft endoporus of metallic pipe coupling is provided with the anti-pollution heat-preserving plastic layer of one deck.

During use, under the obstruct of anti-pollution heat-preserving plastic layer, flow through the hot water on the pipe joint pipe shaft endoporus or the temperature of cold water and can not be subjected to external influence.If pipe is the metal composite water pipe of plastic cement pipe in being used, the metal joint obstruct of hot water or cold water and pipe joint is come, its heat insulation effect will be better.

Compared with the prior art the utility model has transmission during hot water, and heat is difficult for scattering and disappearing, and when carrying cold water, is difficult for drawing external heat, the advantage of high insulating effect.

Fig. 1 is a structural representation of the present utility model.

Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:

As shown in the figure, the utility model comprises a metallic pipe coupling 1, its specialization is that pipe shaft 2 endoporus of metallic pipe coupling 1 are provided with the anti-pollution heat-preserving plastic layer 3 of one deck, anti-pollution heat-preserving plastic layer 3 closely links together by pipe shaft 2 endoporus of Shooting Technique and metallic pipe coupling 1, the both ends of the surface 4 of anti-pollution heat-preserving plastic layer 3 are stuck on the pipe shaft 2 interior hole end surfaces 5, and anti-pollution heat-preserving plastic layer 3 can not spun off in pipe shaft 2 endoporus.

Claims

1, a kind of pipe joint comprises a metallic pipe coupling, it is characterized in that the pipe shaft endoporus of metallic pipe coupling is provided with the anti-pollution heat-preserving plastic layer of one deck.

2, pipe joint according to claim 1 is characterized in that the both ends of the surface of anti-pollution heat-preserving plastic layer are stuck on the interior hole end surface of pipe shaft.
