た。Conventionally, the gas governor or electromagnetic valve in the gas passage is each separate, and the piping shown in FIG. 1, for example, has been used. When the gas ignition knob 1 is turned, the gas cock 2 is opened, and at the same time, the microswitch 3 is turned on, the igniter 4 is activated, and a spark is emitted from the ignition rod 5 with the pilot burner 6 as the cathode. On the other hand, the main electromagnetic valve 7 is opened by a signal from a microcomputer (not shown), and gas flows from the gas cock 2 to the gas passage 8, is pressure regulated by the governor 9, and further flows to the pilot burner 6, where it is ignited. The thermocouple 10 is heated by this pilot flare, a thermoelectromotive force is generated, and the first solenoid valve 11 and the second solenoid valve 12 are sequentially opened and then closed. As is clear from this example, there is a large loss of pressure in the piping connecting the governor 9 and the solenoid valve 7゜11.12 and in the solenoid valve itself, so it is necessary to make the connection port and the main body of the solenoid valve larger. Therefore, the diameter of the plumbing pipe itself had to be increased. In other words, the size of the device itself has become larger.

かできる。According to the above configuration, the piping loss that was observed between the conventional governor and the solenoid valve is almost eliminated.
In addition, the 2' city magnetic valves 32 and 33n can be made smaller, the gas circuit itself can be made simpler and more compact, and, for example, thermal effects can be reduced, and appliances can be made smaller and lighter. Furthermore, the gas passages 12B and B29 to each of the first solenoid valve 32 and the second solenoid valve 33, as well as the pilot gas passage 43, are formed to face the pressure receiving surface 21& of the diaphragm 21 in a substantially perpendicular direction, so that they are made of die-cast material. In terms of manufacturing and processing of the body 14, the bottle is easy to pull out and processing is easy. When even the slightest gas pressure is applied, the first on-off valve 34 always moves in the direction of closing the valve seat 35, resulting in high safety.As described above, according to the present invention, the governor and the plurality of solenoid valves By integrally configuring the pilot gas passage,
This reduces the pressure loss in the piping, making the solenoid valve smaller than conventional solenoid valves, making it possible to make the nine circuits more basic and more compact, and to reduce the pressure loss in the pilot gas passage and multiple solenoid valves. Since the gas passage is arranged almost perpendicular to the receiving surface of the diaphragm and concentrically 1°, it is easy to process with die casting.This gas pressure regulating device has many effects, such as extremely low pressure loss. can be provided.
