Description

 TECHNICAL FIELD

 The present application relates to a gas furnace equipped with a combustion-agent supplying device, specifically, to further improve the combustion-agent supplying device installed in such a gas furnace. Background

The existing gas stove equipped with a combustion-aid-supplying device was proposed by the applicant of this case in the Chinese utility model patent CN9223 ⁴ 162.1, but the original application was found in the commercialization process after many and long-term production The gas and oxygen channels in the case are all located in the same body. Although there are provisions for backfires, there are still unsatisfactory aspects. In the case, two hollow ducts were provided in the threshold, oxygen. The through pipe is separated from the gas in the valve 用 with a special leak-proof rubber part to prevent backfire from leaking, but in case of accident, it is still necessary to mix oxygen with the gas in the atmosphere and burn it. It is more appropriate to put forward further improvements in the technical measures for the combustion-agent-providing device installed in this gas stove.

7 & o 岌 明 's disclosure

 An additional set of oxygen through-tube holders with the same structure are added to the side of the gas through-tube holder of the existing gas stove. The shafts can be equipped with gears that mesh with each other, and their functions are linked. At this time, when the gas knob is twisted, the oxygen valve 转动 also rotates, so that the oxygen supply and the gas supply can be in the atmosphere of the gas stove. Reached to match combustion.

 The above-mentioned structure using the gear linkage to synchronize the flow of gas and oxygen is also realized by a flail method. At this time, a valve shaft end of the valve in the gas pipe seat is equipped with a right-angled pull rod, and the pull rod is used. Twist the handle to make the gas flow larger or smaller. The shaft end of the valve 杼 in the oxygen through pipe seat is correspondingly set to the same structure. Attach the two pull tabs near the handle with two flail joints to make them stronger and more stable. In this way, when the gas control valve is pulled, the gas port on the valve is opened or closed, and the oxygen port in the oxygen control valve is simultaneously increased or decreased.

Another structure that uses the flail method to control the flow of oxygen and gas is the two valve shafts. A turntable is respectively fixed on the two turntables, and a linkage handle is indirectly provided on the two turntables. One end of the linkage handle is pivotally connected to the turntable, and the other end is provided with a guide groove. Then, a pivot pin is arranged on the turntable, so that it is not In the guide groove, a pad is set on the shaft pin to prevent it from falling off when it is actuated, so when the valve shaft is twisted to rotate the turntable, the shaft pin slides in the guide groove, and Traction of the other end of the pivot point to drive the other turntable to rotate in the opposite direction can also achieve the role of the two valve 杼 shaft linkage, so that the oxygen control valve 杼 shaft and the gas control valve 杼 shaft synchronously act.

 In order to make the oxygen and gas combustion action cooperate well, the applicant in this case proposed the following further technical measures for the complete combustion of the oxygen combined gas burner.

 One of the ^ oxygen nozzles of the oxygen tube base is used to supply the oxygen of the gas center burner, that is, a small through tube is set at the nozzle port to enter the gas center burner, and the small through tube separates another A small tube is connected to a special oxygen tube formed in a circular shape on the outer ring of the gas center burner. The other nozzle is to supply oxygen to the gas main burner and mix it with the gas. That is, a small through tube is installed on the nozzle to the main burner of the gas combustion. An oxygen-only tube forming a ring to the outermost part of the main gas burner. Brief description of the drawings

First, turn the part of the gas nozzle that supplies the main burner from the left to the right, because the traditional ignition and gas flow control actions are from right to left. Then insert the outer valve 杼 a into the center hole 11 of the gas-passage socket 10. Then extend the valve shaft A-50 for mounting the manual knob 30 so that a gear A-51 can be added to the extended valve shaft A-50 as shown in FIG. 1. Furthermore, a set of oxygen gas socket A-60 with the same structure as the gas gas socket 10 on the right is installed on the left. The shaft A-61 of the valve 杼 b in the oxygen through pipe seat A ~ ^ 0 must also be lengthened, so that another gear A ~ 62 can be installed on the shaft. The gear A-62 of the oxygen pipe socket A-60 is meshed with the gear A-51 on the right gas pipe socket 10, and can be used for interlocking action. When the manual knob 30 on the valve yoke axis A-50 of the gas pipe socket 10 is turned to the left, the valve 杼 b of the left oxygen pipe socket A "60 will also rotate according to the set amount of oxygen to match the gas quantity. The oxygen supply amount and the gas supply amount are matched and combusted in the atmosphere in the gas burner head.

 As can be seen from Fig. 2, the flail method can also be used to increase or decrease the flow of gas and oxygen at the same time. At this time, a pull lever A-74 at a right angle is added to the shaft A-73 end of the gas flow control valve 杼 A-72 in the left gas pipe socket A-71, and the handle of the pull lever A-74 is used. The twist of A-75 can make the gas flow larger or smaller. The shaft end of the valve 杼 A-85 in the oxygen port holder A-83 is also correspondingly structured. At the same time, the gas pull 杼 A-74 and the right oxygen pull 杼 A- 81 are connected to the handle A-75 with two 用 杼 A-82 to make it more labor-saving and stable. When the gas pump is pulled, the gas port on the Minyan A-72 is opened or closed, and the oxygen port is also increased or decreased with synchronization. '

 As shown in FIG. 3, another structure for controlling the flow of oxygen and gas by using flail is to fix a turntable A-52 and A-63 on the two valve stem shafts A-50 and A-61, respectively. A-52 and A-63 are rotated as their valve shafts A-50 and A-61 are twisted, and the two turntables A-52 and A-63 are connected by a linkage handle A-64. One end of the linkage handle is pivotally connected to an appropriate part of the turntable A-52, and the other end is firstly provided with a guide groove A-65 on the handle, and then a shaft pin A-66 is provided on the turntable A-63 and the It is set in the guide groove A-65, and a pad 圏 A-67 is set on the shaft pin A "66 to prevent it from falling out of the guide groove A-65 when it is actuated. When the stern shaft A-50 is twisted to drive the turntable A "63, the pin A-66 will slide in the guide slot A-65, and the other pivot point will be pulled to drive the other turntable A-52 to Rotating in opposite directions can also achieve the linkage of the two valve yoke shafts A-50 and A-61, so that the oxygen valve yoke and the gas valve yoke can operate synchronously.

 The two oxygen nozzles A "65, A" 66 of the oxygen through-tube socket A-60 shown in Figure 4, the right-hand nozzle A-66 supplies the oxygen for the gas center burner A-90, that is, the nozzles A ~ 66 A small oxygen pipe A-101 is connected to the gas center burner at the mouth, and the small pipe is divided into another small pipe A-102 for the oxygen pipe which is formed in a circle on the gas center stove A-90. . As for the nozzle A-65 on the outer left side of the oxygen pipe socket A ^ O, it supplies oxygen to the main burner A-91 of the gas and mixes it with the gas. That is, an oxygen small pipe A-103 to In the main burner A-91 for gas combustion, the small tube is also divided into a small tube A-104 to the outermost part of the gas burner to form a special tube A-95 for oxygen combustion.

 The above two ring-shaped through-pipes specifically for oxygen combustion can make the oxygen in the through-pipe pass inside and outside to surround the gas, which is beneficial to achieve the effect of complete combustion.

As for the small oxygen pipes A-101 and A-103, the amount of oxygen directly passed into the gas burner A-90 and the main burner A-91 must be controlled to prevent gas from being burned when the amount of gas is small. The phenomenon of oxygen blowing out. Industrial applicability

 The application of the improved technology to the gas furnace equipped with a fuel supply device is effective in practice. These improvement measures not only have a simple structure and are easy to implement, but also can synchronize the oxygen supply with the gas supply in the atmosphere. It is completely burned in medium, which can make obvious effects in reducing environmental pollution and saving energy. In addition, since this kind of gas stove does not need any additional operation in use, it is even more popular with users.
