In order to obtain a large gas flow rate, gas pressure regulators that control primary pressure are used. For this reason, the passage leading to the gas pressure regulator after passing through the electromagnetic valve is complicated, making it difficult to obtain a sufficient flow rate and causing problems in processing and assembly.

る。 The present invention aims to eliminate these disadvantages, and its purpose is to simplify the structure by reducing the number of bends in the gas passage, and to create a device that connects a solenoid valve and a gas pressure regulator. The valve seat of the electromagnetic valve and the valve seat of the gas pressure regulator are orthogonal to each other, and the outlet on the electromagnetic valve side is communicated with the primary pressure chamber of the gas pressure regulator.

A is the main body of the device, and the electromagnetic device 2' is attached from above, and the valve 10 is held in a closed position by a spring on the valve seat 3. On the other hand, the valve seat 3 communicates with the primary pressure chamber 5 of the gas pressure regulator 1 on the lower side, and is arranged perpendicularly to the valve seat 4 of the gas pressure regulator 1. An outer cover is attached via a diaphragm 8 and a pressure regulating spring 9. On the other side, a secondary pressure chamber 6 is formed via a valve seat 4 and a valve 7, and serves as an outlet 12.

A large capacity gas flow rate can be obtained. Since gas is supplied to the primary pressure chamber simultaneously with the opening of the solenoid valve, the response performance of the diaphragm is also improved. In addition, although the explanation was made with the solenoid valve located at the top due to the structure,

する。 Therefore, according to the present invention, by orthogonally arranging the valve seat of the solenoid valve and the valve seat of the pressure regulator, a large capacity pressure regulation function can be maintained, and the gas after passing through the solenoid valve can be Compared to a complicated configuration in which a through hole or communication hole is formed separately to lead to the primary pressure chamber of the pressure regulator, it is easier to prevent pressure loss, reduce leakage points, and process through holes and blind them. This has the effect of eliminating inconveniences such as an increase in the number of assembly parts such as lids.
