To achieve the above object, the utility model adopts the technical scheme that pipe connections, including joint body；And mistake
Body is crossed, the transition duct bodies are fixedly connected with the joint body, and the transition duct bodies are connected with the junction block body phase；Increase
Strong body, the enhancing body is fixedly connected with the transition duct bodies, and the enhancing body is connected with the transition duct bodies；Even
Joint, the connector is fixed and is set in the enhancing tubular body, and the connector is connected with the transition duct bodies；It is described
Sealing water channel is provided with connector.
In the embodiment of the utility model one, the sealing water channel has several, the recessed connector of sealing water channel.
In the embodiment of the utility model one, the first water shutoff platform, end seal water platform, described first are provided with the connector
Water shutoff platform protrudes along the connector axial direction, and the end seal water platform is outwardly along the connector radial direction；It is described
Sealing water channel is located between the first water shutoff platform and end seal water platform.
In the embodiment of the utility model one, end seal tank is provided with the end seal water platform.
In the embodiment of the utility model one, connection screw thread is set on the connector.
In the embodiment of the utility model one, the enhancing body includes bulge loop, and ladder platform, the ladder platform and institute
State bulge loop to be fixedly connected, Reinforced Hoop is set in the ladder platform periphery；The thickness of the wall of the bulge loop is more than the transition duct bodies
Wall thickness.
In the embodiment of the utility model one, the transition duct bodies include arc tube wall, and the arc tube wall connects with described
Seamlessly transitted between the tube wall of head tube body.
The utility model has the advantages that：
By setting Reinforced Hoop so that metal connector is tightly encased by enhancing body outside, metal insert and modeling are improved
Close adhesion between material, it is to avoid package power subtracts caused by the body portion of plastic material deforms under high-temperature condition
It is small, so as to cause fluid seepage.The utility model by metal Reinforced Hoop limit to a certain degree plastics and metal connector it
Between divide, it is to avoid produce crack, improve the safety coefficient of pipe connections.Setting sealing water channel extension liquid is further advanced by ooze
The circuit of leakage, can effectively mitigate Seepage.

Embodiment
With reference to embodiment and accompanying drawing（1 to 3）The utility model will be further described.
Pipe connections involved by the utility model, including joint body 1, transition duct bodies 2, enhancing body 3, the joint
Body 1, transition duct bodies 2 and enhancing body 3 are the transition duct bodies 2 and the joint body 1, described by integrated injection molding
Enhancing body 3 is connected.The transition duct bodies 2 include arc tube wall 200, the arc tube wall 200 and the joint body 1
Tube wall between seamlessly transit.In other embodiments, the transition duct bodies 2 can also be non-arc, i.e. transition duct bodies 2
The diameter parallel of tube wall and transition duct bodies 2.
Enhancing body 3 internal sleeve is provided with connector 4, and the connector 4, which is fixed, to be nested in the enhancing body 3
Portion, the connector 4 is metal connector, preferably copper or plating copper connecting head, and the connector 4 is hollow form, as needed
44 can be threaded on metal connector 4, the screw thread 44 can be external screw thread or internal thread, screw thread 44 is easy to other
Loose joint between the object being engaged, easy installation and removal.If without using loose joint mode, it is welding that can typically use, but this
Thermofussion welding mode is repaired once being molded later stage inconvenience.
The enhancing body 2 includes bulge loop 21, ladder platform 22, and the ladder platform 22 is with the bulge loop 21 by integrally forming
Type, the external diameter of the ladder platform 22 is less than the external diameter of the bulge loop 21.The thickness of the wall of the bulge loop 21 is more than the transition duct bodies 2
Wall thickness, play a part of enhancing pipe junction intensity.Reinforced Hoop 5 is set in the periphery of the ladder platform 22, with the rank
Halfpace 22 is interference fitted.Meanwhile, the periphery of the joint body 1 is also arranged with Reinforced Hoop 5, can so make pipe connections both sides
