Abstract
The utility model relates to a 3-way structure used to connect aluminum plastic compound pipes, which comprises a 3-way body and three connecting ports. A tightening nut with screw threads is arranged on each connecting port and a pressing copper ring is arranged on the outer round surface of the pipe. A connecting element is arranged on the connecting ports to form a one-body structure with the connecting ports. The utility model has a simple structure and low production cost but improves the match of the connecting ports of a 3-way structure with different materials. The steady and reliable use provides effects as good as those of copper 3-way structures.
Description
Technical field
The utility model relates to a kind of water heating fittings, especially a kind of three-port structure that is used to connect aluminium-plastic composite pipe.
Background technique
Water heating fittings is used quite extensive, and the three-way union that connects water pipe is one of them.Three-way union of the prior art generally adopts copper product to make, structure comprises the three-port structure body, compresses copper ring, locking screw emits, body is provided with outside thread, compressing copper ring is sleeved on the pipe fitting, emitting by locking screw makes pipe fitting connect with body again, this kind structural type is commonplace, using effect is good, the situation of generation leakage seldom, but the manufacture cost height, international especially in recent years copper material price is very high, considers from the angle of economical with materials cost, also the someone has designed a kind of aluminium-plastic composite pipe three-port structure of replacing whole copper, and structure is consistent with the copper threeway.But in actual use, occur leakage, situation such as fragile, insecure easily, brought very big inconvenience to productive life.The three-port structure that designs a kind of new structure of rational in infrastructure, safety and stability has very big economic benefit and social benefit.
Summary of the invention
Originally the purpose that is model utility is a kind of simple in structure, easily manufactured, combined type three-port structure that cost is low of design, and the technical solution of the utility model is so to realize:
A kind of combined type three-port structure, comprise threeway body and three connection ports, each connection port is provided with the copper ring that compresses that tapped locking screw emits and be located at the pipe periphery, connection port (12) locates to be provided with link (3), described connection port (12) is fixedly connected with link (3), is integral the formula structure.
As preferably, link (3) one ends are provided with and manage the profile of tooth interface (7) that is connected, and the other end connects with connection port (12).
As preferably, locking screw emits (1) to be double layer construction, in establish tapped metal layer (21), skin is the plastic-aluminum layer.
As preferably, connection port (12) exterior edge face is provided with ring groove (9), and described link (3) end face is provided with annular boss (8), and described annular boss (8) connects with threeway body (4) with the corresponding setting of ring groove (9), fastening connection piece (3).
As preferably, annular boss (8) outer ring surface of link (3) bottom is provided with concaveconvex structure (11), and described concaveconvex structure (11) is corresponding with the end face concaveconvex structure (13) of connection port (12).
As preferably, threeway body (4) is made by aluminium plastic material, and link (3) is a copper spare.
As preferably, metal layer (21) periphery is provided with the annular groove that connects interlock with the plastic-aluminum layer.
As preferably, annular boss (8) opening end also is provided with location snap ring (17) and one group of recess (15), the interlock of convenient and ring groove (9).
The utility model has designed a kind of simple in structure, combined type three-port structure that cost is low.Different with plastic-aluminum combined formula three-port structure of the prior art is, has mainly improved the interface end of three-port structure and the cooperating structure of different materials, has following characteristics:
1, rational in infrastructure, the technical program is divided into original body threeway body (4) and link (3) two-part cleverly, adopts annular boss (8) and ring groove (9) fastening between two-part, and both are into a single integrated structure to make it, and are during use, reliable and stable.
2, low cost of manufacture, it is the main material of threeway that the technical solution of the utility model adopts aluminium plastic material, interface end adopts copper spare, greatly reduces manufacture cost, has saved resource.
3, the interface end of threeway adopts that copper spare guaranteed to use does not leak, safety, has the using effect the same with the copper three-port structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
