This utility model is achieved in that a kind of rustless steel collecting pipe component, makes including with rustless steel Supervisor, the sidewall weld of supervisor has the side arm made with copper material, supervisor dock with side arm Position, the sidewall global formation of supervisor has a bit of sleeve pipe, side arm to insert in this sleeve pipe, side The pipeline section being positioned at this sleeve pipe of arm is a bit of necking pipe.

As preferred forms, this utility model also can use following attached technical scheme.

One end of described supervisor is welded with the port tube made with copper material, at described supervisor and this port tube pair The position connect, the end of described supervisor is a bit of flared tube, and port tube inserts in flared tube；Or, At the position that described supervisor is docked with this port tube, the end of described supervisor is a bit of necking pipe, port Pipe inserts in this necking pipe, convex at the lateral wall global formation limited location of port tube, limit convex limit end Mouth pipe inserts the degree of depth of necking pipe.

The other end of described supervisor is welded with the tail end arm made with copper material, props up with tail end described supervisor The position of pipe docking, the end of described supervisor is a bit of necking pipe, and tail end arm inserts in this necking pipe, Convex at the lateral wall global formation limited location of tail end arm, limit convex limit tail end arm and insert necking pipe The degree of depth.

The utility model has the advantages that, side arm is inserted in the sleeve pipe of supervisor's sidewall, and side props up The pipeline section being positioned at sleeve pipe of pipe is a bit of necking pipe, thereby enhances rustless steel supervisor and side arm Between welding fixing.

Detailed description of the invention

The overall structure of rustless steel collecting pipe component as it is shown in figure 1, include the supervisor 1 made with rustless steel, The sidewall weld of supervisor 1 has several side arms 2 made with copper material, one end of supervisor 1 be welded with The port tube 3 that copper material is made, the other end of supervisor 1 is welded with the tail end arm 4 made with copper material.Other The quantity of side branch 2 is decided according to the actual requirements.

Each side arm 2 all uses the structure shown in Fig. 2 with being responsible for 1 position docked.Such as Fig. 2 Shown in, at the position that supervisor 1 is docked with side arm 2, the sidewall global formation of supervisor 1 has a bit of Sleeve pipe 1a, side arm 2 inserts in sleeve pipe 1a, and the pipeline section being positioned at sleeve pipe 1a of side arm 2 is A bit of necking pipe 2a.This structure shown in Fig. 2 enhances rustless steel supervisor 1 and side arm 2 Between welding fixing.Sleeve pipe 1a can use and pull out hole technique global formation on the sidewall of supervisor 1.

The position that supervisor 1 is docked with port tube 3 uses the structure shown in Fig. 3.As it is shown on figure 3, leading The position that pipe 1 docks with port tube 3, the end of supervisor 1 is a bit of flared tube 1b, port tube 3 Insert in flared tube 1b.If port tube 3 external diameter than supervisor 1 internal diameter little, then supervisor 1 with The position of port tube 3 docking can also use the another kind of structure shown in Fig. 4.As shown in Figure 4, leading The position that pipe 1 docks with port tube 3, the end of supervisor 1 is a bit of necking pipe 1c, port tube 3 Insert in necking pipe 1c, at the lateral wall convex 3a of global formation limited location of port tube 3, by limit convex 3a Restrictive ports pipe 3 inserts the degree of depth of necking pipe.Limit convex 3a also has another to act on, with continuous tunnel furnace The when of weld port pipe 3 and supervisor 1, bronze weld-ring can be limited with limit convex 3a and be enclosed within port tube 3 The degree of depth of end, makes bronze weld-ring be clipped between the end face of limit convex 3a and supervisor 1, it is ensured that bronze weldering Being accurately positioned of ring.Structure shown in Fig. 3 and Fig. 4 enhances between rustless steel supervisor 1 and port tube 3 Welding fixing.

The position that supervisor 1 is docked with tail end arm 4 uses the structure shown in Fig. 5.As it is shown in figure 5, The position that supervisor 1 is docked with tail end arm 4, the end of supervisor 1 is a bit of necking pipe 1d, and tail end props up Pipe 4 inserts in necking pipe 1d, at the lateral wall convex 4a of global formation limited location of tail end arm 4, by limiting The convex 4a in position limits tail end arm 4 and inserts the degree of depth of necking pipe 1d.Limit convex 4a also has another to act on, With continuous tunnel furnace welding tail end arm 4 and supervisor 1 when, bronze weldering can be limited with limit convex 4a Ring set, in the degree of depth of tail end arm 4 end, makes bronze weld-ring be clipped in the end face of limit convex 4a and supervisor 1 Between, it is ensured that being accurately positioned of bronze weld-ring.Structure shown in Fig. 5 enhances rustless steel supervisor 1 and tail Welding fixing between end arm 4.

Above-described embodiment is preferred embodiment of the present utility model, all structures similar with this utility model and The equivalence change made, all should belong to protection category of the present utility model.
