Abstract
The invention relates to a gas supply coupling and method of assembly for the delivery of combustion gases to a combustion chamber of a heating device, the gas supply coupling including a crimp ring which provides a metal-to-metal seal between the gas supply tube and the gas supply line.
Description
The application is the U.S. Patent application No.11/282 that submitted on November 18th, 2005,931 part continuation application.
Technical field
The present invention relates to for the gas supply coupling that natural gas is transported to the combustion chamber of water heater.
Background technology
Pot-type boiler uses electric power or ignitable fuel that a certain amount of water is heated, and uses as required for house-owner.Described fuel can comprise propane or natural gas, and these propane or natural gas will be transported near the combustion chamber the water tank.Described fuel is in the combustion chamber internal combustion, thereby with the water heating, and water maintained predetermined temperature.For to the combustion elements supply with transport fuel, the combustion chamber is led to the outside of water heater usually.This can produce a passage, so that other gases can enter combustion elements.
Water heater combustion chamber prevents external firing by the combustion chamber that utilizes inhibition gas to flow to the functional sealing of outside, combustion chamber.Yet the sealed combustion chamber meeting is so that the manufacturing of water heater and assembling complicated.Sealed combustion chamber has reduced a plurality of assembling tolerances between control module/adjuster and the burner.In addition, the gas supply must be by a hermatic door that is used for transmitting combustion fuel.A hermatic door like this comprises expansion connector and the nut counterpart that is positioned between air feed circuit (this air feed circuit is in the outside extension in combustion chamber) and the inner air supply pipe.Even if this is effectively, related attaching parts are relatively more expensive, cause the manufacturing cost of each water heater to increase.
Summary of the invention
A kind of gas supply coupling that is used for burning gases are transported to the combustion chamber of heater according to an illustrative aspects of the present invention, described gas supply coupling comprises: block piece, it is adapted to fit in one and leads in the opening of combustion chamber; Counterpart, it is fixed to described block piece; Air supply pipe, it is fixed on the described counterpart; The air feed circuit; And corrugated ring, this corrugated ring is provided at the sealing of metal to metal between described air supply pipe and the described air feed circuit.
A kind of method to assembling for the gas supply coupling that burning gases is transported to the combustion chamber of heater according to an illustrative aspects of the present invention, the method may further comprise the steps: make described air supply pipe by described counterpart location; Make described air supply pipe flexible with respect to the air feed circuit at overlapping; And connect described air supply pipe and described air feed circuit at described overlapping by corrugated ring.
Description of drawings
Those skilled in the art from following to understanding each feature and advantage of the present invention the current detailed description of the preferred embodiment.The accompanying drawing of detail specifications is below described briefly:
Fig. 1 is the overall side view of the gas supply coupling of the water heater among the present invention;
Fig. 2 A is the exploded view that is used for the counterpart of gas supply coupling;
Fig. 2 B is the front view that is used for the plate of gas supply coupling; And
Fig. 2 C is the side cutaway view that is installed in the counterpart of Fig. 2 A in the opening that limits in the outer cover of water heater.
The specific embodiment
Fig. 1 shows the total stereogram for the gas supply assembly 10 of water heater components 12.This water heater components 12 comprises outer cover of water heater 14, and this shell 14 can be separated into and comprise water tank 16 and combustion chamber 18.Be furnished with burner 20 in combustion chamber 18, burner 20 is tightly near water tank 16.Gas supply assembly 10 of the present invention is designed to transport of fuel is arrived burner 20, with near burning water tank 16, thereby the water in the water tank 16 is heated to predetermined temperature.Gas supply assembly 10 will be connected to fuels sources, and in this preferred embodiment, this fuels sources is natural gas, but what it is contemplated that is that gas supply assembly 10 can be used for other fuel types (comprising propane).Thereby the opening 22 that air feed enters of being convenient to that combustion chamber 18 comprises combustion elements and leads to water heater 12 outsides.Yet this opening 22 also can form for outer member and gas and enter path in the burner 20.
With reference to Fig. 2 A, connector 26 comprises having step-like neighboring 38 (Fig. 2 B) to be used for being received into the plate 36 in the block piece 24 (Fig. 1).This plate 36 has non-circular profile, and is nailed to or is welded in the block piece 24 and on the air supply pipe 30, yet also can adopt other attachment means.
With reference to Fig. 2 C, air supply pipe 30 is directly sentenced stacked or flexible relation in interface 40 within it and is received air feed circuit 28.It should be understood that also can adopt other protruding/recessed receiving system.
Corrugated ring 42 forms the metal to metal seal between air supply pipe 30 and the air feed circuit 28 at interface 40 places.A corrugated ring 42 like this can be the corrugated ring by the Lokrin manufacturing of Florida Bartow.The contact stress that corrugated ring 42 provides high being enough to make a part of interface 40 plastic yieldings between air supply pipe 30 and the air feed circuit 28, thus sealing circumferential, permanent, metal to metal formed.Corrugated ring 42 helps to form permanent connection, and has avoided the use meeting is deteriorated along with the time and leak elasticity or rubber seal, O shape ring or packing ring.Corrugated ring 42 can satisfy all standards that are welded to connect basically, just need not to carry out described connection with heat.
Although it should be understood that the set-up mode that discloses in the embodiment shown particular elements, the present invention enlightens to some extent to other set-up mode.
Although illustrate, describe and claimed specific order of steps, what however, it should be understood that is, unless otherwise indicated, can be with any order, carry out these steps individually or combinedly, and the present invention enlightens to some extent to these steps.
It is exemplary more than describing, and the restriction of can't help wherein limits.Can make multiple modification and improvement to the present invention according to above-mentioned instruction.Although disclose preferred embodiment of the present invention, those of ordinary skills it will be appreciated that some modification will fall within the scope of the present invention.Therefore, it should be understood that within the scope of the appended claims, can implement the present invention to be different from above concrete described mode.Therefore, claims be should study and true scope of the present invention and content determined.
