Abstract
The utility model relates to a connecting pipe fitting for the hot-melt connection of composite pipes. The utility model comprises a through or an elbow pipe fitting body; an inner cavity of a port of the pipe fitting is provided with an annular lug boss; the inner side of the port of the pipe fitting is provided with a material containing ring groove. In connection, the annular lug boss and the end face of a composite pipe are directly contacted and connected after hot melt; the material containing ring groove can store plastic melt mass to prevent overflow and simultaneously keep the beautiful appearance of an integral pipeline system. The utility model has the advantages of simple structure, easy fabrication, low cost and convenient installation and operation.
Description
Technical field
The utility model relates to a kind of connection pipe fitting, the connection pipe fitting that particularly a kind of composite pipe hot melt connects.
Technical background
The composite pipe that is composited by the inwall and the plastic outer layer of metallic material such as stainless steel or aluminium during with two or many link circuits, generally adopts hot melting way that both are bonding; Connection pipe fitting is also protected the exposed plastic body in composite pipe port and the bond gap of metal inner surface except playing interconnect function.
Someone proposed a kind of hot melt grafting pipe fitting (patent No.: patent application 01251235), it is made of the upper shield of main pipe body and interface end; The upper shield of main pipe body end can also can directly be enclosed within on the main pipe body by being threaded with main pipe body, can be connected with main pipe body by other any one mode.
Above-mentioned patent need be used auxiliary solution plastic melt excessive of upper shield, and overall structure is relatively complicated, and cost is higher.
Summary of the invention
The connection pipe fitting that the utility model provides a kind of composite pipe hot melt to connect comprises straight-through or bend pipe tools body, and the inner chamber of pipe fitting port is provided with annular boss 1, and pipe fitting port inboard is provided with and holds material circular groove 2.During connection, annular boss 1 directly contacts with the composite pipe end face, connects behind the hot melt; Hold material circular groove 2 and can stockpile plastic melt, prevent to have kept the attractive in appearance of whole pipe-line system again excessive the time.
As preferably, annular boss 1 highly equal or be slightly larger than cooperate the wall thickness of tubing, the outer wall of composite pipe can both fully be contacted with boss side surfaces with inwall.
As preferably, annular boss 1 is 0.5～2 times of bore to the distance of pipe fitting end face, plays leading role for the insertion of composite pipe.
As preferably, hold the width of expecting circular groove 2 and approximate wall thickness, hold forming molten chamber between material circular groove 2 and the composite pipe, the volume that melts the chamber can enough retain the plastic melt that hot melt produces, to keep the attractive in appearance of whole pipe-line system.
As preferably, it is outer ring convex 3 about the wall thickness twice that pipe fitting end is provided with width; The outer surface of outer ring convex 3 is that isometrical smooth surface, outside end face are smooth flat, and right angle, two sides or chamfering transition connect.
As preferably, pipe fitting can be two logical, threeway, four-way.
Effect of the present utility model is, compared with prior art, the utility model only needs a body part, and is simple in structure, makes easily, and cost is low, and is easy to install.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Specific embodiment
As shown in Figure 1, the connection pipe fitting that the utility model composite pipe hot melt connects comprises straight-through or bend pipe tools body, and the inner chamber of pipe fitting port is provided with annular boss 1, and pipe fitting port inboard is provided with and holds material circular groove 2.Boss 1 highly equal or be slightly larger than cooperate the wall thickness of tubing, the outer wall of composite pipe can both fully be contacted with boss side surfaces with inwall.Boss 1 is 0.5～2 times of bore to the distance of pipe fitting end face.The width that holds material circular groove 2 approximates wall thickness.It is outer ring convex 3 about the wall thickness twice that pipe fitting end is provided with width, and the outer surface of outer ring convex 3 is that isometrical smooth surface, outside end face are smooth flat, and right angle, two sides or chamfering transition connect.
