Abstract

A gas supply interface includes a door adapted to fit within an opening to a combustion chamber, the door includes a serrated opening.

Description

The gas supply interface of water heater

Technical field

The disclosure of this text relates to a kind of gas supply interface that natural gas is sent to the combustion chamber of water heater.

Background technology

The device of the fuel of utilization such as propane or natural gas needs the connection between a plurality of elements.Provide various connections.Though effectively Connection Element is quite expensive at present, welding or the brazing that still need carry out the complicacy installation of fuel-device connect.

Summary of the invention

According to the instance part of the disclosure of Ben Wenben, a kind of gas supply interface comprises and is assemblied in door of driveing in the opening of combustion chamber and the feed tube that is formed with flange, and this feed tube is received in and makes this flange butt door in the zigzag opening.

A kind ofly be assembled to the method for device according to the gas supply interface that is used for transmitting fuel gas of instance of the present disclosure, this method comprises that supplying circuit with gas is inserted in feed tube; Feed tube is inserted the zigzag opening of driveing the door in the opening of combustion chamber through being assemblied in; Prop up zigzag opening extruding feed tube.

Description of drawings

Through following detailed description to the preferred embodiment of the present invention, each feature and advantage of the present invention will be more obvious.The accompanying drawing of describing in detail is summarized as follows:

Fig. 1 is the major side view that the gas of the water heater of the embodiment of the invention is supplied interface;

Fig. 2 is the perspective 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 with door of zigzag opening; With

Fig. 4 B is the sectional view of cutting open along Fig. 4 A center line 4B-4B.

The specific embodiment

Fig. 1 explains the main stereogram of the gas provisioning component 10 that uses water heater components 12.Although the disclosed in this embodiment situation that is to use water heater components 12 is construed as and uses device or any other such as gas-cooker, baking box, stove, water heater, combustion chamber, cloth dryer, oven of any other type to use the situation of equipment, valve, adjuster or other gas control equipment of combustion gas or petrogas also can benefit from this invention.

Water heater components 12 comprises outer cover of water heater 14, and this outer cover of water heater 14 is divided to comprise water tank 16 and combustion chamber 18.Burner 20 is set in the combustion chamber 18 and is close to water tank 16.Thereby gas provisioning component 10 of the present invention is designed to send fuel near to burner 20 confessions burning water tank 16 water in the water tank 16 is heated to predetermined temperature.This gas provisioning component 10 will be connected on the fuel supply source, although gas provisioning component 10 also uses other fuel type that comprises propane, a preferred embodiment of the fuel supply source here is a natural gas.Combustion chamber 18 comprises out to the outside opening of water heater 12, to make things convenient for supply gas and near combustion elements.

Gas provisioning component 10 is set in the opening 22 of combustion chamber 18, and the opening 22 of extend past combustion chamber 18.This gas provisioning component 10 comprises door 24, can close the path (Fig. 2) that gets into combustion chamber 18 thereby door 24 is constituted as to fall to being sitting in the opening 22.In the embodiment of a disclosed nonrestrictive water heater components, door 24 can be arc at least and its size is about the 10*3.5 inch, and this size can provide maintenance facility etc. usually.Door 24 can form interface 26, and this interface 26 can provide interconnecting between gas supply circuit 28 and the feed tube 30.In a non-limiting example, gas supply circuit 28 can be the flexible wires that is connected to fuel supply source.In a non-limiting example, feed tube 30 is the rigid pipes that have the port of export 32 at burner 20 places, is used for sending fuel to burner 20.

Like Fig. 3, door 24 is supplied circuit 28 with gas and is received in the zigzag opening 34 (also like Fig. 4 A) that directly is formed at wherein.Zigzag opening 34 is formed by a plurality of tusks or other crenellation.That is to say that zigzag opening 34 is the non-circular openings in the door 24.Here be interpreted as multiple zigzag thing and all be alternative use.

Feed tube 30 comprises flange 36, when feed tube 30 is inserted in the zigzag opening 34, this flange 36 within it side against door 24.In case feed tube 30 is inserted in the zigzag opening 34, feed tube 30 will be therein direct receiver gases supply circuit 28 and 40 form overlapping or be inserted in relation in the interface section.Here be interpreted as also can adopting other the moon/sun to receive configuration.

Crimp rings (crimp ring) 42 provides the metal to metal seal between supply pipe 30 and the gas supply line road 28 at 40 places, interface section.A kind of such crimp rings 42 can be the crimp rings from the Lokring of Bartow manufacturing of Florida State.Crimp rings 42 generally includes the interior diameter of inclination; The interior diameter of this inclination can provide contact pressure, this contact pressure be sufficiently high to make the interface section 40 between feed tube 30 and the gas supply line road 28 part generation plastic deformation and form the permanent metal to metal seal of circumference.Crimp rings 42 is convenient to permanent engagement and can be avoided the use of elasticity or rubber seal, O type ring or the packing ring of passing in time and degenerating and take place to leak.Crimp rings 42 satisfies all standards that are welded to connect in itself, and is same except not: forming this kind connection does not need heating.

In case be crimped, crimp rings 42 also need prop up zigzag opening 34 extruding feed tube 30 and rotate therein when assembling to prevent feed tube 30.That is to say that zigzag opening 34 is connected to guarantee firm and irrotational attached with the material composite that forms flange 36 at least in part.

Although be construed as here and disclose a kind of specific arrangement of components in this embodiment, other configuration also can obtain an advantage from the present invention.

Although showed, described and stated specific sequence of steps here, be construed as except as otherwise noted, these steps can be undertaken by any order, and individually or in combination, and these steps also can obtain an advantage from the present invention.

Above description only be to be used for illustrating but not to be used for limiting the present invention.In view of the above description, can make multiple modification and variation to the present invention.Here disclose the preferred embodiments of the present invention, yet those skilled in the art can understand the particular implementation regular meeting and fall in the scope of the invention.Therefore, be construed as here within the scope of the appended claims, the present invention not only ad hoc fashion of available description implements also available embodied in other.Therefore, should study following claim to confirm actual range of the present invention and content.
