Abstract
The utility model provides an air current limiting device for a smoke tube of a gas appliance. The air current-limiting device comprises an air current limiting ring. The air current limiting ring is in a hollow circular plate structure. The external diameter of the air current limiting ring is matched with the internal diameter of an outer tube of the coaxial smoke tube. A round hole is arranged at the center of the air current limiting ring. The diameter of the round hole is bigger than the external diameter of an inner tube of the coaxial smoke tube. An edge of the air current limiting ring is provided a flanging. When a person chooses the air current limiting device for the smoke tube of the gas appliance, the person can ensure that an air inlet channel of the coaxial smoke tube is provided with an appropriate an air inlet cross section. In the process of assembly, the air current limiting device is disposed in the air inlet channel of the coaxial smoke tube of the gas appliance through the flanging in sleeved mode. The air current limiting ring can decrease the cross section of the air inlet channel of the coaxial smoke tube. Through replacement of the air current limiting rings with different round-hole diameters, air inflow rate can be adjusted when a gas water boiler burns. The air current limiting device has the advantages of being simple in structure and convenient to use. Through the utilization of the air current limiting device, the air inflow rate is easy to adjust when the gas water boiler burns. Consequently, service power and heat exchange efficiency of the gas water boiler achieves the best effect.
Description
Technical field
The utility model relates to condensed type combustion gas heating hot water stove or gas instantaneous water heater.
Background technology
The existing employed smoke exhaust pipe of gas water-heating furnace is to adopt the coaxial-type smoke pipe basically, and its function is from outdoor suction fresh air and preheating, and waste gas after burning is discharged outdoor.Suction, aiutage with the spindle balance smoke pipe are a concentric sleeve; Outer layer sleeve suction chamber outer air; The power situation is not influenced by outdoor wind-force, because when the air suction inlet of wind to exterior wall, equally blow on the flue gas discharge opening yet; Both suffered pressure is identical, so furnace pressure can not change (this also is the cause that is called as balanced type).Simultaneously, the flue gas of discharge can improve the family expenses machine thermal efficiency with the fresh air preheating.
Do not have the air inlet current-limiting apparatus in the same spindle balance smoke pipe that adopts in the existing gas water-heating furnace, can not regulate the air inlet amount, can only make the heat exchange efficiency that reaches preferable through regulating the ratio that gas flow is regulated air and combustion gas.Yet when gas flow was turned down, the power of water heater had also decreased.
Through regulating air inlet amount (air-fuel ratio) is one of effective measures that improve condensed type combustion gas water heater heat exchange efficiency.
Summary of the invention
The purpose of the utility model is a kind of air current-limiting apparatus that is used for combustion gas tool smoke pipe of design, and the air inlet amount during its adjustable fuel gas water heater burning improves the gas water-heating furnace heat exchange efficiency.
The technical scheme of the utility model is:
A kind of air current-limiting apparatus that is used for combustion gas tool smoke pipe; Comprise a restrictor ring; Said restrictor ring is a hollow plectane structure, and its overall diameter is suitable with the internal diameter of the coaxial smoke pipe outer tube of combustion gas tool, and the central authorities of restrictor ring have circular hole; The overall diameter of managing in the coaxial smoke pipe of the diameter of circular hole greater than the combustion gas tool, the edge of restrictor ring has flange.
Restrictor ring has plurality of specifications, and the restrictor ring of different size has different overall diameters and different Circularhole diameters.
During use; The utility model cover is set in the inlet channel of coaxial smoke pipe of combustion gas tool; Normally cover is set in the exhaust outlet end of the nearly gas-heating water heater of coaxial smoke pipe; Restrictor ring reduces the inlet channel cross section of coaxial smoke pipe, through changing the restrictor ring of different Circularhole diameters, and the air inlet amount in the time of can regulating the gas water-heating furnace burning.
The utlity model has characteristics simple in structure, easy to use, the air inlet amount when regulating the gas water-heating furnace burning easily makes the use power and the heat exchange efficiency of gas water-heating furnace reach optimum efficiency.
Description of drawings
Fig. 1 is the structure and use sketch map of the utility model.
Fig. 2 is the A-A cutaway view among Fig. 1.
Fig. 3 is the use sketch map of the utility model.
The specific embodiment
With reference to figure 1, Fig. 2 and Fig. 3; A kind of air current-limiting apparatus that is used for combustion gas tool smoke pipe comprises a restrictor ring 3, and restrictor ring 3 is a hollow plectane structure; Its overall diameter D is suitable with the internal diameter of the outer tube 2 of the coaxial smoke pipe of combustion gas tool; The central authorities of restrictor ring 3 have circular hole 30, and the diameter d of circular hole 30 is greater than the external diameter f of the interior pipe 1 of the coaxial smoke pipe of combustion gas tool, and the edge of restrictor ring 3 has flange 31.Restrictor ring 3 has plurality of specifications, and the restrictor ring 3 of different size has different overall diameter D and different Circularhole diameter d.
During use, restrictor ring 3 is set in through flange 31 cover in the inlet channel 20 of exhaust outlet 41 ends of nearly gas-heating water heater 4 of the coaxial smoke pipe of combustion gas tool, restrictor ring 3 reduces the cross section of the inlet channel 20 of coaxial smoke pipe.Through the restrictor ring 3 of changing different Circularhole diameters, the air inlet amount in the time of can regulating gas water-heating furnace 4 burnings, the ratio of air and combustion gas is for best when making the water heater burning.
