Abstract
The utility model discloses a composite pipe component used for various pipeline systems, which is characterized in that a pipe and the pipe wall of a pipe joint are in a composite structure. The pipe wall is composed of an inner wall, a reinforcing lining and an outer wall. The inner wall and the outer wall made of polyethylene material and the reinforcing lining made of metal material are adhered by adhesive agent. The reinforcing lining is outward exposed on the end part of the pipe. The end surface of the pipe wall forms an annular rabbet. The bottom part of a stepped hole on the pipe joint is provided with an annular groove. The depth and the position of the annular groove are matched with the rabbet. The utility model has the advantages of light weight, high strength, convenient installation and operation, no corrosion, no scale formation and good freezing resistance.
Description
The utility model relates to a kind of composite pipe fitting that is used for various pipe-line systems.
At present, the pipe fitting that is used for various water supply, air supply system generally adopts galvanized pipe, and drainage system adopts cast iron tube or linerless plastic tube.Galvanized pipe and cast iron tube be Heavy Weight not only, not flexible, Hui Zhi, install inconvenient, and easy-to-rust, easily fouling, not freeze proof.Linerless plastic tube then resistance to compression and anti-seismic performance is lower, and application area is restricted.
The purpose of this utility model provides a kind of in light weight, and intensity is higher, and is easy to install, and the composite pipe fitting of not corrosion, non-scaling, good frost resistance.
The technical solution of the utility model is, this composite pipe fitting comprises pipe and pipe joint, it is characterized in that, the tube wall of described pipe and pipe joint is a composite structure, be that the composition of tube wall is followed successively by inwall from inside to outside, strengthens lining and outer wall, it is bonding that the inside and outside wall of being made by polythene material and the reinforcement lining of metallic material pass through tackiness agent.The connection of tube and tube joint is the shoulder hole nested structure, end at described pipe, the inside and outside wall material of tube wall is removed, strengthening lining exposes, form the tenon of annular at the tube wall end face, corresponding with it, in pipe joint upper shoulder hole bottom an annular groove is arranged, its position and the degree of depth match with above-mentioned tenon.During installation, the junction plane of pipe and pipe joint adopts adhesive bonding.The form of pipe joint can adopt straight coupling, elbow, tee union or multiple-pass joint as required.
The utility model has the advantages that in light weight, antidetonation, compressive strength are higher, and be difficult for burn into non-scaling, good frost resistance, simultaneously can crooked easily, Hui Zhi, pipe and pipe joint do not need scyewed joint and directly by tenon and groove fit and to stick with glue agent bonding, install and use very convenient.
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Fig. 1 is an overall structure schematic representation of the present utility model;
Fig. 2 is the structural representation of tube wall;
Fig. 3 is the partial structurtes schematic representation of tube and tube joint in conjunction with end face;
Fig. 4 is the structural representation of straight coupling;
Fig. 5 is the structural representation of elbow.
As shown in Figure 1 and Figure 2, this composite pipe fitting comprises pipe 1 and pipe joint 2, and the composition of tube wall is followed successively by inwall 3 from inside to outside, strengthens lining 4 and outer wall 5, and it is bonding that the inside and outside wall of being made by polythene material and the reinforcement lining of metallic material pass through tackiness agent.Pipe 1 is the shoulder hole nested structure with connecting of pipe joint 2, end at described pipe 1, the inside and outside wall material of tube wall is removed, strengthening lining exposes, form the tenon 6 of annular at the tube wall end face, corresponding with it, in pipe joint upper shoulder hole bottom an annular groove 7 is arranged, its position and the degree of depth match (as shown in Figure 3) with above-mentioned tenon 6.During installation, the junction plane of pipe and pipe joint adopts adhesive bonding.The form of pipe joint 2 both can be the tee union shown in Fig. 1, also can adopt Fig. 4, straight coupling and elbow shown in Figure 5 as required, perhaps multiple-pass joint.
