Abstract
The invention relates to the technical field of gas water heater equipment, in particular to a gas water heater exhaust tube comprising a tube body made of stainless steel material. The gas water heater exhaust tube is characterized in that the interior of the tube body is in an X shape, the cross is communicated, the left and right sides of the X shape are provided with sealed cavities filled with sound-absorbing foam, the upper and lower sides are provided with sealed cavities filled with the sound-absorbing foam, and positions of the tube body contacting with the gas are provided with heat resisting and isolating layers. The gas water heater exhaust tube is capable of preventing gas from reversing, noise is reduced, and the heat insulation performance is fine.
Description
Technical field
The present invention relates to gas heater equipment technical field, be specifically related to a kind of smoke exhaust pipe of gas water heater.
Background technology
In the prior art, gas heater needs the flue gas produced after fuel gas buring to drain into outdoor through smoke exhaust pipe, part smoke pipe must be arranged on outdoor, when outside wind pressure is too large, outdoor air pours in down a chimney the combustion chamber entering gas heater from smoke exhaust pipe, directly cause adverse effect to the combustion position in gas heater main frame.When gas heater main frame is in low load combustion state, the wind that burned flame is easily poured in down a chimney by outdoor and enters is gone out; When there is on the other hand downdraught, the flue gas after most of fuel gas buring cannot be discharged, and the combustion gas in burner cannot the enough auxiliary air of injection and produce imperfect combustion, thus produces excessive CO, causes adverse effect to the safety of user.Cause there is low load combustion situation and outdoor wind is larger time, the defects such as gas heater main frame cisco unity malfunction.For overcoming these defects, the Anti-downdraft smoke tube of gas heater is improved.
Summary of the invention
For the problems referred to above, the invention provides one and can prevent down draught, reduce noise, the smoke exhaust pipe of gas water heater of good heat insulating.
Realize technical scheme of the present invention
Smoke exhaust pipe of gas water heater, comprise smoke exhaust pipe body, described smoke exhaust pipe body is stainless steel material, described smoke exhaust pipe inside is X-shaped, and described X-shaped infall is interconnected, and is the cavity of two sealings about X-shaped, attraction foam is filled with in cavity, upper and lower both sides are sealed cavity, are provided with sound-absorbing foam in cavity, and described smoke exhaust pipe body and gas contact portion are equipped with heat-resisting insulating layer.
Adopt such scheme, because smoke exhaust pipe inside is X-shaped, described X-shaped infall is interconnected, and is the cavity of two sealings about X-shaped, upper and lower both sides are sealed cavity, when wind enters, X-shaped can block wind, can prevent down draught, sound-absorbing foam is provided with in cavity, can reduce noise, described smoke exhaust pipe body and gas contact portion are equipped with heat-resisting insulating layer, can strengthen the insulation effect of gas heater.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.Wherein:
Fig. 1 is structural representation of the present invention.
In figure, 1 smoke exhaust pipe body, 2 is X-shaped, and 3 is cavity.
Detailed description of the invention
As shown in the figure, smoke exhaust pipe of gas water heater, comprise smoke exhaust pipe body 1, described smoke exhaust pipe body 1 is stainless steel material, described smoke exhaust pipe inside is X-shaped 2, described X-shaped 2 infall is interconnected, X-shaped about 2 is the cavity 3 of two sealings, sound-absorbing foam is filled with in cavity 3, upper and lower both sides are sealed cavity 3, sound-absorbing foam is provided with in cavity, described smoke exhaust pipe body 1 is equipped with heat-resisting insulating layer with gas contact portion, because smoke exhaust pipe inside is X-shaped 2, described X-shaped 2 infall is interconnected, X-shaped about 2 is the cavity 3 of two sealings, upper and lower both sides are sealed cavity 3, when wind enters, X-shaped 2 can block wind, down draught can be prevented, sound-absorbing foam is provided with in cavity, noise can be reduced, because smoke exhaust pipe body and gas contact portion are equipped with heat-resisting insulating layer, the insulation effect of gas heater can be strengthened.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
