Abstract
A kind of gas supply interface includes the door being assembled in the opening being opened to combustor, and this door includes zigzag opening.
Description
Technical field
The disclosure of this text relates to the gas supply interface of a kind of combustor that natural gas is sent to water heater.
Background technology
The device utilizing the fuel of such as propane or natural gas needs the connection between multiple elements.It is provided with various connection.Although the most effective connecting element is fairly expensive, but need for carrying out the complicated welding installed of fuel-device or brazing connection.
Summary of the invention
According to an exemplary aspect of the present disclosure, a kind of gas supply interface includes the door being assemblied in the opening being opened to combustor and is formed with the feed tube of flange, and this feed tube makes this flange abut door in being received in zigzag opening.
A kind of method being used for the gas supply interface transmitting fuel gas is assembled to device of example according to the disclosure, the method includes gas supply connection is inserted in feed tube；Feed tube is inserted through the zigzag opening of the door being assemblied in the opening being opened to combustor；Prop up zigzag opening extruding feed tube.
Accompanying drawing explanation
By the following detailed description to the preferred embodiment of the present invention, each feature and advantage of the present invention will become apparent from.The accompanying drawing described in detail is summarized as follows:
Fig. 1 is the main side view of the gas supply interface of the water heater of the embodiment of the present invention；
Fig. 2 is the perspective cross-sectional view of the gas supply interface of water heater；
Fig. 3 is the exploded view of gas supply interface；
Fig. 4 A is the front view of the door with zigzag opening；With
Fig. 4 B is the sectional view cut open along Fig. 4 A center line 4B-4B.
Detailed description of the invention
Fig. 1 illustrates to use the main axonometric chart of the gas provisioning component 10 of water heater components 12.Although being disclosed that the situation using water heater components 12 in this embodiment, it should be appreciated that for using any other type of such as gas-cooker, baking box, stove, water heater, combustor, cloth dehydrator, the device of oven or any other to use the situation of combustion gas or the equipment of petrogas, valve, actuator or other gas control equipment also can benefit from this invention.
Water heater components 12 includes outer cover of water heater 14, and this outer cover of water heater 14 is divided in order to include water tank 16 and combustor 18.In burner 20 is arranged on combustor 18 and be close to water tank 16.The gas provisioning component 10 of the present invention is designed to that fuel sends to burner 20 and for burning near water tank 16 thus the water in water tank 16 is heated to predetermined temperature.This gas provisioning component 10 will be connected on fuel supply source, although gas provisioning component 10 also uses other fuel type including propane, but fuel supply source here preferred embodiment is natural gas.Combustor 18 includes being opened to the opening outside water heater 12, to facilitate supply gas and close to combustion elements.
Gas provisioning component 10 is arranged in the opening 22 of combustor 18, and extends past the opening 22 of combustor 18.This gas provisioning component 10 include door 24, door 24 be configured to fall to being sitting in opening 22 in thus the path (Fig. 2) entering combustor 18 can be closed.In the embodiment of water heater components nonrestrictive disclosed in, door 24 can be at least arch and its size is about 10*3.5 inch, and this size generally can provide maintenance convenient.Door 24 can form interface 26, and this interface 26 can provide being connected with each other between gas supply connection 28 and feed tube 30.In one non-limiting embodiment, gas supply connection 28 can be attached to the flexible wires of fuel supply source.In one non-limiting embodiment, feed tube 30 is to have the rigid pipe of the port of export 32 at burner 20, for fuel sends to burner 20.
Such as Fig. 3, gas supply connection 28 is received in the zigzag opening 34 (also such as Fig. 4 A) being formed directly therein by door 24.Zigzag opening 34 is formed by multiple tusks or other crenellation.It is to say, zigzag opening 34 is the non-circular openings in door 24.Here being interpreted as multiple zigzag thing is all alternative use.
Feed tube 30 includes flange 36, and when feed tube 30 is inserted in zigzag opening 34, this flange 36 is within it against door 24.During once feed tube 30 is inserted into zigzag opening 34, feed tube 30 will directly receive gas supply connection 28 wherein and forms overlap in interface section 40 or be inserted in relation.Here it is interpreted as may be used without the configuration of other male/female receipt.
Crimp rings (crimpring) 42 provides the metal to metal seal between supply pipe 30 and gas supply connection 28 at interface section 40.A kind of such crimp rings 42 can be from the crimp rings that the LokringofBartow of Florida State manufactures.Crimp rings 42 generally includes the interior diameter of inclination, the interior diameter of this inclination can provide contact pressure, and this contact pressure is sufficiently high to plastic deformation occurs so that a part for the interface section 40 between feed tube 30 and gas supply connection 28 and forms the permanent metal to metal seal of circumference.Crimp rings 42 is easy to permanent engagement and is avoided that use passage in time and degenerates and elasticity or rubber seal, o-ring or the packing ring leaked occurs.Crimp rings 42 meets all specifications being welded to connect in itself, except not same: form this kind of connection and need not heating.
Once being crimped, crimp rings 42 is also required to prop up zigzag opening 34 and extrudes feed tube 30 to prevent feed tube 30 from rotating wherein when assembling.It is to say, zigzag opening 34 is connected with the material composite forming flange 36 to ensure firm and irrotational attachment at least in part.
Although it should be understood that disclose a kind of specific assembly configuration in this embodiment, but other configuration also can obtain an advantage from the present invention.
Although showing, describing and stating specific sequence of steps here, it should be appreciated that for except as otherwise noted, these steps can be carried out in any order, either individually or in combination, and these steps also can obtain an advantage from the present invention.
Above description is intended merely to illustrate rather than for limiting the present invention.In view of the above description, it is possible to the present invention is made numerous modifications and variations.There has been disclosed the preferred embodiments of the present invention, but, those skilled in the art will appreciate that particular implementation regular meeting falls within the scope of the present invention.Therefore, it should be understood that within the scope of the appended claims, the present invention not only can implement by the ad hoc fashion described, it is also possible to embodied in other.Therefore, it should research the claims below is to determine the actual scope and content of the present invention.
