From the valve opening state (rotation angle of the rotating shaft 23 of 0 degrees) shown in Figure 丨 and Figure 2, after driving the gear motor 21 to rotate the rotating shaft 23 in the forward direction through the transmission mechanism 22 In response to them, the cam member 42 mounted on the square shaft 23 is rotated, and the operation lever 4 is moved horizontally (right side of the figure). Also, in the position shown in FIG. 4 (A), the operation lever 4 is moved When it reaches the front, press the wide body 32 in the direction of the magnet case 31 (the rotation angle of the rotation shaft 23 is 63 degrees). At this time, since the second communication hole 51a of the rotating disk 51 has not reached the first communication hole of the fixed disk 52, The first hole 52a (refer to FIG. 4 (B)), so the fuel gas does not flow toward the gas outlet 14. When the rotary shaft 23 is further rotated, the operation lever 4 starts to retract. At this time, the solenoid of the electromagnetic safety valve 3, Received from the codebook paper size set on the rotation axis ^ 1226420 V. Description of the invention (8) The signal of the device 25 is excited, and the electromagnetic safety valve 3 is kept in the open state. Next, the operation lever 4 is retracted at the position shown in Fig. 5 (the rotation angle of the "rotation axis" 93 degrees). At this time, since the second communication hole 5ia of the rotating plate 51 has not yet reached the first hole 52 of the first communication hole of the fixed plate 52 (refer to FIG. 5 (B)), the fuel gas will not face the gas. The outflow port 14 flows. After rotating the rotating shaft 23 again, the second communication hole 51a of the rotating disk 51 and the first hole 52a of the fixed disk 52 are aligned so that the internal passages Ua and Ub communicate with the gas outflow portion 14a. At this time, The fuel gas flowing into the internal passage 13a'nb flows through the flow regulating valve 5 toward the gas outlet 14 and reaches the position shown in FIG. 6 (A) (the rotation angle of the rotation shaft 23 is 170 degrees), and then the gas is directed toward the gas. Ignition of the burner. At this time, the fuel gas with the gas burner having a strong gas flow rate is caused to flow toward the mixing tube of the gas burner through the gas flow outlet 4. In addition, the electromagnetic safety valve 3 is closed within a certain time after the rotation angle of the rotating shaft 23 reaches 70 degrees, for example, when the flame of the burner is not detected by the thermocouple located near the gas burner. After the gas burner is ignited, the rotary shaft 23 is further rotated to a position not shown in FIG. 6 after the rotary disk 51 is rotated, so that the second communication hole 51 a and the second and third holes 52 b and 52 c are the same ( The rotation angle of the rotation shaft 23 is 230 degrees). At this time, the gas burner is a medium-gas gas flow fuel gas, which flows through the gas flow outlet 14 toward the burner's mixing pipe. Furthermore, when the rotary shaft 23 is further rotated to the position shown in FIG. 6 (C), and the rotary disk 51 is rotated, the second communication hole 51a is aligned with the two holes 52c and 52d of the third and fourth holes (rotation). The rotation angle of the shaft 23 is 270 degrees). At this time, the gas combustion is a fuel with a weak gas flow. The gas flows through the gas flow outlet 1226420 A7 V. Description of the invention (9) 14 and flows toward the mixing pipe of the burner. Next, the rotary shaft 23 is further rotated to the position shown in FIG. 6 (D), and then the rotary disk 51 is rotated so that the second communication hole 51a coincides only with the fourth hole 52 (1 (rotation angle of the rotary shaft 23) 295 °). At this time, the gas burner with the minimum gas flow rate of the fuel gas flows through the gas flow outlet 14 and flows toward the combustion /% pipe. When you want to increase the firepower of the gas, you only need to turn the motor 21 The reverse rotation may be performed by rotating the rotating shaft 23 in the reverse direction. Here, referring to FIG. 7, the gas combustion of the gas valve i of the present invention, which is converted by the gas supply amount of natural gas and city gas toward the gas burner, will be described as: The change in the amount of combustion (Kcal). The line a is used as the first comparative example, which indicates that when the interval and opening area of the holes 52a., 52b, 52c, 52d and the opening area of the second communication hole 5a are set, When the second communication hole 5U blocks each of the holes 52a, 52b, 52c, and 52d of the first communication hole, and the same as the adjacent hole, the change in the amount of combustion is changed. In this type, the gas flow is large. In the city gas, switch from the "" to the second hole 52b Near the point ai, the gas flow is drastically adjusted to reduce the amount of combustion, and at the same time, the amount of combustion near the point 1 is smaller than the amount of fire in the gas burner. Also, natural gas with a smaller gas flow rate Gas, when the fire power of the gas burner is adjusted from medium to weak fire and from weak fire to minimum, as shown by points C and a3, the amount of combustion can be temporarily increased. Line B is the second comparative example, which indicates that each setting is set. When the intervals and opening areas of the holes 5 仏, 52b, 52〇, 5 2 d and the opening area of the second communication hole $ 1 & are such that the second communication hole 51a does not block each of the holes 52a of the first communication hole, 52b, 52c, 52d and in accordance with the order and the adjacent hole, the burning amount of this paper is applicable to the Chinese standard (CNS) M specifications ⑵ ο 7 public magic (Please read the precautions on the back before filling (This page)-Order 丨 ¥! 1226420 A7 ---------- -B7 V.
