The method will be described below with specific examples. As shown in FIG. 1 and FIG. 2, the synchronous controller of the present invention comprises an outer sleeve 10, an inner sleeve 20, a control rod 4〇 coaxially connected with the inner sleeve 2〇, and a gas rotary adjustment switch, the control rod 40 and The gas rotary flap is fixedly connected, and the size of the gas here is controlled by the general duty. The mechanical rotation _ rod 40, the circumscribing inner sleeve is the same as the 10 and the gas rotation control switch, the former changes the furnace head air inlet, and the latter adjusts the 201028621 gas size 'both to achieve synchronous control. As shown in Figures 3, 4 and 5, the outer circular wall 1〇5 of the outer sleeve 10 is provided with an air inlet 103 through which the fish is ventilated, and an air outlet (10) connected to the surface of the wind. The air inlet 103 is used to connect the fan. Wind pipe. The end of the outer sleeve (10) is closed and at the center of the circle (9), the connection _ control switch and the control lever 40. The other end of the inner sleeve 20 is sequentially connected with a sealing rubber 5, a sealing rubber ring 550, and a sealing cover 30 to seal σ. In order to facilitate the adjustment of the intake air amount of the air, an intake adjusting hole 2〇3 is further disposed on the inner sleeve 2〇, and the intake adjusting hole period may be a series of blind holes or through holes which are mutually side by side. Or more than one, the intake adjustment hole plus _ amount and the defensive type can be called God can also be gradually increased. In order to prevent air leakage during use, a sealing rubber ring 5〇〇 and a sealing rubber ring 55〇 are provided on the outer wall of the inner sleeve 1G and the outer portion of the outer sleeve 2〇. The compliant cover 30 is a circular ring having a circular hole 3〇2 in the circular plate 301, and the other end of the sealing cover 30 is connected to the air inlet of the burner. The control lever 4 is a stepped circular shaft, and includes a connecting portion 202 which is connected in series with the _403, the circular shaft 4〇1 and the airless control switch. Also on the connecting portion 202 is a women's locating pin 60 for fixed connection with the gas rotation control. As shown in FIG. 3 and FIG. 6 'the inner sleeve 2 is a cylinder closed at one end, and the outer diameter thereof is matched with the inner diameter of the outer sleeve 10 so that the inner sleeve 2G can be rotated in the outer sleeve 四 (4); the inner sleeve 2 is the cylinder wall The air outlet hole 201028621 201' with the air outlet cutting and the air inlet adjusting hole 2〇3 is opened. The air outlet 201 is smaller than the air inlet port 1〇3 on the outer sleeve 1〇. The distance between the air outlet 201 and the air intake adjusting hole 2〇3 corresponds to the distance between the air outlet 11〇 of the outer sleeve 1〇 and the air inlet 103, and at least the positional relationship is ensured as follows: the air outlet 201 and the air inlet When the 103 is completely coincident, the air intake adjusting hole 203 is also completely coincident with the air inlet 0 103, that is, fully open, and the external air from the air outlet 103 passes through the air intake adjusting hole 2〇3 and the air outlet to enter the inner 参 套The cylinder 20' then enters the circular hole 302 through the air hole on the inner sleeve 20 and the outer sleeve 1 〇 upper air outlet (10) to reach the burner head; 2. When the air outlet 201 and the air inlet 103 are completely staggered, each one enters The air conditioning holes 203 are all disjointed from the air inlet 103, that is, fully closed, that is, no external air is supplied through the air inlet 1〇3 to give the tuyere 11〇, no air is added; 3. the air outlet 20 is adjusted by the air inlet adjusting hole 203 The degree of coincidence/staggering with the air inlet 1〇3 is positively correlated with the degree of the intake air adjustment amount. Mouth 曰幵 Considering the different _ and fabric quality (4) devices need to have specific adjustments to _ the best. Therefore, the air intake adjusting hole 203 on the inner sleeve has more than one blind hole and a through hole, and the number of the through holes should satisfy the minimum maximum air intake volume, and the light is lightly related to the actual wire, and the force needs to be increased. When the maximum air intake volume is available, you can make the most adjustments. As shown in Figure 3, the assembly process of the entire controller is as follows: first insert the inner sleeve rib into the outer sleeve K) Install the control rod 40, and then use the positioning lock 6 to lock on the control rod 4 (four) stop service 're-sleeve sleeve Μ 丝 密 塾 2010: 201028621 seal _50. Then put the hard 3Q up, the dense 3Q and the outer sleeve Chuan y welded connection 'can also be fixed with screws, if it is the latter, add another ring on the jacket with 10 - a ring with several threaded holes 1〇4, at the same time, the hole of the mounting screw 50 is also opened on the sealing cover, and then locked by the screw 50, and the connecting portion of the control rod 40 is fixed with the gas control switch, and can be directly or indirectly connected and controlled. A gas valve that controls the amount of gas. When in use, as long as the control lever 4 is rotated, under the action of the fan, the external atmosphere passes through the connected air inlet 1〇3, the intake adjusting hole 2〇3, the air outlet hole, the circular hole 301, and then enters the gas furnace. In the mixed combustion with gas, in order to make the gas burn full time, it is necessary to make the seam and line flow of the surface gas. The air flow can be adjusted as follows: in the first-time adjustment of the scale, the gas and Air combustion, while using the instrument to test the flame color, so that it can be determined whether the combustion is sufficient. When it is determined that the air flow is insufficient, as shown in Fig. 6, firstly, the adjustment hole of the through hole is tested on the inner wall of the inner sleeve 20. Is it sufficient, if not enough, to increase the through hole adjustment hole 2〇3 by drilling through the prefabricated eyelet. The test method is to rotate the control rod 40' to connect and then add wind to the burner and ignite the gas. At the same time, use the instrument to test or visually test the color of the fire 'by determining whether it is fully burned. When it is determined that the air flow is insufficient, it will drill more. The intake air adjustment hole 203 'until the instrument is tested to complete combustion' and then gradually rotates the control lever 40 and repeatedly drills the intake air adjustment hole 2〇3 and detects whether it is completely burned until it is fully opened, and the drilling operation is at the first When drilling in the second time, the second time can be used directly without the need to re-drill adjustment. In this way, when used later, the fuel can be automatically adjusted while adjusting the gas flow rate of 201028621. " The inner sleeve 20 according to the present invention as shown in Fig. 7 may also be provided with no air holes 2 (H, but directly adjusted by the intake air, and the exhaust gas is right as shown in the figure.
