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 It is exhaust passage in pipe, outer straight pipe and outer bend pipe constitute outer tube, and the gap between outer tube and exhaust pipe is inlet channel, Exhaust passage emits exhaust gas, and inlet channel comes in outside air transmission, and sealing is equipped in the end port of outer straight pipe Ring closes the end port of inlet channel, and taper shield is equipped in the end port of interior straight pipe.

During actual welding, the welding surface width range of supporting block is selected in 10-15mm, and the width range is advantageous In being welded and fixed, while material is not also wasted, the supporting block in the present embodiment is the cylindrical shape with both ends open, the structure Design can be used automation equipment and realize self-feeding, and in welding, since cylindrical shape supports in transmission feeding process The systematicness of block can pick up supporting block and be welded, and need to weld at two without considering the directionality of supporting block, and only, Save welding sequence and weld interval.
