Abstract

The utility model relates to a combustion gas pipe of a water heater. The side edge of the segmenting part of the gas pipe has a connecting hole, the side edge of a block pipe has a gas outlet hole, and the block pipe and a gas connecting nozzle are connected or integrally formed; besides, the block pipe is sheathed with a copper foil sleeve which is postpositive in the connecting hole. After the copper foil sleeve is heated in the gas pipe, the joining part between the block pipe and the inner edge of the gas pipe forms a copper film which makes the block pipe and the gas pipe closely melted and fixed without gaps. Therefore, the utility model has the effects of quick manufacture and safe block.

Description

Combustion gas pipe of water heater

The utility model relates to a kind of burning gas pipe of water heater special use.

General gas heater, it all can be divided into several sections firepower such as high, medium and low, the size of firepower then depends on the quantity that nozzles are lighted on the gas pipe in the burner, so that 14 nozzles to be arranged on the gas pipe is example, high section firepower then 14 nozzles is all lighted, the nozzles that the stage casing firepower is then lighted both sides are about about 10, and low section firepower is then lighted mid portion; And the quantity of lighting for nozzles, general gas heater all must be intercepted in the gas pipe on its burner, so that the blocking section that the nozzles on the control gas pipe are lighted.And general commercially available water heater, the obstruct of its gas pipe is that this gas pipe is cut into three sections, incision is respectively put the iron plate of a uiform section then, by spot welding its mouthful engaged, again its joint is polished, this traditional gas pipe blocking method is very time-consuming, though tried various bonding, stop up or add method such as chemical agent and all fail, because of gas pipe is to use for gas, and gas has powerful corrosivity, utilize the bonding iron plate wherein of chemical agent, the initial stage is perhaps no problem, after a period of time, begun chemical change, there is slot the bonding place, and gas is leaked, and is abnormally dangerous.

The utility model provides a kind of processing easy, the gas pipe of structural safety at the shortcoming of above-mentioned traditional gas pipe barrier structure.

The gas pipe of the burning of a kind of water heater that the utility model provides, it is mainly combined by institutes such as gas pipe, nozzles, Copper Foil covers; Its main feature is: this gas pipe is desired segmentation place side and is provided with connecting hole, its side of one obstructing tube is provided with venthole, this obstruct piping is connected with the gas connection or is one-body molded, and insert in the connecting hole behind the sheathed Copper Foil cover on this obstructing tube, Copper Foil forms copper film in obstructing tube and gas pipe inner edge joint after being enclosed within and heating in the gas pipe, makes both tight blows, saturating slit reaches the effect of obstruct safely.

Below, in conjunction with the accompanying drawings structure of the present utility model, feature and effect are described further.

Fig. 9 is the part stereogram of another possible embodiments of the utility model.

Figure 10 is the user mode figure of embodiment among Fig. 9.

At first, seeing also Figure 1 and Figure 2, is gas pipe 1 in the middle of this burner base A, which is provided with some nozzles 2, both sides are bluff piece 3, and the bottom has a bolt 4 to join with controller, be provided with connecting hole 10, one Copper Foils cover 5 its leading edges in the dual-side of this gas pipe 1 and form a flange 50; One obstructing tube 6, its lateral border is provided with the venthole 60 of outside opening, this obstructing tube 6 is to be connected on the gas connection 7, or it is one-body molded with it, the leading edge of this gas connection 7 is an air admission hole 70, the external diameter of this obstructing tube 6 is identical with spatial altitude within the gas pipe 1 again, after this obstructing tube 6 is inserted in Copper Foil cover 5, place in the gas pipe, and the flange 50 of this Copper Foil cover 5 is fixed on periphery outside the connecting hole 10, as shown in Figure 2, Copper Foil cover 5 not heating as yet this moment, the venthole 60 of this obstructing tube 6 is covered by within the Copper Foil cover 5.

See also shown in Figure 3 after 5 fusions of Copper Foil cover, after this Copper Foil cover 5 is heated to uniform temperature, i.e. fusing forms a copper film 51, around tube wall, seal, the copper film 51 that the flange 50 in its place ahead is formed is also with gas connection 7 and gas pipe 1 sealing, make it not have the slit, and via the venthole 60 in obstructing tube 6 outsides, and reach the purpose of segmentation obstruct.

The utility model user mode, please consult shown in Figure 4 again, general gas heater, it all can be divided into high and low, medium several sections firepower, when gas is entered by the direction of arrow of bolt 4 and since the obstruct of obstructing tube 6 only can supply in the middle of some nozzles 2 light, again because the venthole 60 of this obstructing tube 6 is outside opening, when gas enters from air admission hole 70, nozzles 2 that can unidirectional supply both sides.

Please consult another embodiment shown in Figure 5 again, this obstructing tube 6 can place under the nozzles 2 again, side venthole 60 outside this obstructing tube 6, can upwards enlarge again and tilt to nozzles 2 pivoted holes 13 places, form another kind of segmentation obstruct mode, when the direction of gas according to arrow, when air admission hole 70 enters, remove the nozzles 2 that can supply side, also can directly supply the nozzles 2 of top, its user mode as shown in Figure 6.

Shown in Figure 7, for the barrier structure of the utility model one is implemented illustration again, it is to utilize identical obstructing tube 6, but there is not any venthole, its periphery puts Copper Foil cover 5, desire segmentation obstruct place at gas pipe, obstructing tube 6 is inserted the location, when Copper Foil cover 5(figure does not show) after the fusion, form copper film 51, and wall fluid-tight engagement within obstructing tube 6 and the gas pipe 1 is reached the purpose of segmentation obstructs, and this gas connection 7 can be located at the appropriate location of segmentation baffle area, reaches another kind of segmentation with the gas pipeline that cooperates water heater and heats pattern.

The user mode of the embodiment of Fig. 7, see also shown in Figure 8, this gas connection 7 is located at side appropriate location outside the obstructing tube 6, when gas is entered by the air admission hole 70 of gas connection 7, because obstructing tube 6 intercepts, make the methane gas such as the direction of arrow, only the nozzles 2 for the baffle area use, and reach the gas pipe of effective segmentation.

Another possible embodiments figure of the utility model shown in Figure 9, this gas pipe 1 is provided with a circular hole 14 at pivoted hole 13 place's root edges of relative nozzles 2, can be inserted in Copper Foil cover 5 backs for an obstructing tube 6 embeds, and be provided with a microscler venthole 60 outside this obstructing tube 6 lateral margin week, the height and the width of this obstructing tube 6 are just identical with gas pipe 1 internal diameter again, Copper Foil cover 5 fusion backs form copper film 51, and this obstructing tube 6 is combined closely mutually with gas pipe 1.

Please consult shown in Figure 10 again, when methane gas is entered by air admission hole 70, then methane gas as shown by arrows, the nozzles 2 of supply top and venthole 60 sides use, and another side of relative venthole 60, since the obstruct of obstructing tube 6, and make gas can not flow to another side, and reach the effect of segmentation obstruct.
