In order to solve the above-mentioned technical problem, concrete scheme provided by the utility model is as follows: one kind being used for gas heating stove
Or the smoke exhaust pipe of gas heater, it is that the double-skin duct constituted, the bilayer straight tube are docked by the double-deck straight tube and the double-deck bend pipe
Including outer straight pipe and the interior straight pipe being fixed in outer straight pipe, the bilayer bend pipe includes outer bend pipe and is fixed on outer bend pipe
Interior interior bend pipe is equipped with supporting block between the outer straight pipe and interior straight pipe, between the outer bend pipe and interior bend pipe, described
Supporting block is to be welded and fixed；The supporting block is the cylindrical shape with both ends open.
Preferably, the welding surface width range of the supporting block is 10-15mm, which is conducive to be welded and fixed,
Material is not also wasted simultaneously.
Preferably, the quantity of the supporting block is 3, and the quantity of the supporting block is 3, the supporting block uniform intervals
It is set on same cross section, when support block welding of the quantity advantageously ensures that the concentricity of inner and outer pipes, while saving material.
Preferably, the outer bend pipe is the outer bend pipe of ripple, and the interior bend pipe is bend pipe in ripple, so that welding is easy.
Preferably, the interior straight pipe and interior bend pipe constitute exhaust pipe, are exhaust passage, the outer straight pipe in exhaust pipe
Outer tube is constituted with outer bend pipe, the gap between outer tube and exhaust pipe is inlet channel, and exhaust passage emits exhaust gas,
Inlet channel comes in outside air transmission.
Preferably, sealing ring is equipped in the end port of the outer straight pipe closes the end port of inlet channel.
Preferably, taper shield is equipped in the end port of the interior straight pipe.
Compared with prior art, the utility model has the beneficial effects that: the utility model is by using cylindric branch
Outer straight pipe and interior straight pipe, outer bend pipe and interior bend pipe is welded and fixed in bracer, realizes the investment for reducing human cost, improves
Production efficiency is conducive to the industrial competition for increasing enterprise.

Specific embodiment
It is right below in conjunction with the attached drawing of the utility model embodiment in order to which the technical solution of the utility model is described in detail
The technical solution of the utility model embodiment carries out clear, complete description.Obviously, described embodiment is the utility model
A part of the embodiment, instead of all the embodiments.Based on described the embodiments of the present invention, the common skill in this field
Art personnel every other embodiment obtained under the premise of being not necessarily to creative work, belongs to the model of the utility model protection
It encloses.
Please refer to Fig. 1-Fig. 6, it is provided in this embodiment a kind of for gas heating stove or the smoke exhaust pipe of gas heater,
It is that the double-skin duct constituted is docked by the double-deck straight tube and the double-deck bend pipe, the double-deck straight tube includes outer straight pipe and is fixed on outer straight pipe
Interior interior straight pipe, the double-deck bend pipe include outer bend pipe and the interior bend pipe that is fixed in outer bend pipe, outer straight pipe and interior straight pipe it
Between, fixed by welding supporting block between outer bend pipe and interior bend pipe, supporting block is the cylindrical shape with both ends open, outer bend pipe
For bend pipe outside ripple, interior bend pipe is bend pipe in ripple, so that welding is easy, interior straight pipe and interior bend pipe constitute exhaust pipe, exhaust
