Technical field: the utility model relates to the Welding Structure between a kind of gas heater heat exchanger pipe fitting.
Background technology: in the prior art, set scolder is non-close ring in gas heater heat exchanger water pipe junction, be that a breach is arranged on the annular ring, during installation, if gap position up, soldering fusing back scolder runs off at gap position easily, the weldering phenomenon appears leaking in indentation, there, and between annular scolder and the water pipe surface for line contacts, contact range is little, causes the easy landing of scolder of having good positioning.For overcoming above-mentioned these defectives, the Welding Structure between the gas heater heat exchanger pipe fitting is developed.
Summary of the invention: technical problem to be solved in the utility model is the Welding Structure that will provide between a kind of gas heater heat exchanger pipe fitting, it can effectively improve the sealing that connects between the pipe fitting and the uniformity of welding, promotes the welding quality of pipe fitting.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises pipe fitting, scolder, pipe fitting contains water inlet pipe, U type pipe, straight tube, outlet pipe, water pipe head, connect for matched in clearance between the pipe fitting, described scolder is closed flat torus, scolder is socketed on the matched in clearance place that is connected between the pipe fitting by torus, and toric inside and outside anchor ring is connected the pipe fitting tube wall respectively with two outer, inner surface contact integrally welded.
Described scolder also is provided with annular edge, and torus and annular edge link into an integrated entity.
Become 80 °～hexagonal angle degree between described torus surface and the annular edge surface.
Described pipe fitting, scolder are that aluminum alloy materials is made.
Described pipe fitting, scolder are that Cu alloy material is made.
Described pipe fitting is that stainless steel material is made, and scolder is that nickel alloy material is made.
Described toric inside and outside anchor ring be connected with two respectively the pipe fitting tube wall outer, inner surface is integrally welded by soldering.
Described toric inside and outside anchor ring be connected with two respectively the pipe fitting tube wall outer, inner surface is integrally welded by soldering.
Described toric inside and outside anchor ring be connected with two respectively the pipe fitting tube wall outer, inner surface is integrally welded by soldering.
Described toric inside and outside anchor ring be connected with two respectively the pipe fitting tube wall outer, inner surface is integrally welded by soldering.
The utility model is compared the beneficial effect that is produced with background technology:
1, because the utility model adopts the scolder between the gas heater heat exchanger pipe fitting to change closed flat torus into by non-close ring, scolder is socketed on the matched in clearance place that is connected between the pipe fitting by torus, toric inside and outside anchor ring is connected outer, the inner surface contact welding of pipe fitting tube wall respectively with two, make the scolder of soldering fusing be evenly distributed in gap location, so it can effectively improve the sealing that connects between the pipe fitting and the uniformity of welding, promote the welding quality of pipe fitting.
