Specifically, the gas inlet 102 communicates with the gas source passage 2. A gas storage space is defined between the electromagnet assembly 200 and the pilot head 300, and the gas inlet channel 301 and the gas outlet channel 302 are respectively communicated with the gas storage space.
The operation of the solenoid valve device 1 according to the embodiment of the invention is described below with reference to the drawings.
First, gas enters the valve body 100 through the gas inlet 102, and then enters the gas storage space through the gas inlet channel 301 in the pilot head 300. When the electromagnet assembly 200 is in the blocking position, the electromagnet assembly 200 blocks the air outlet channel 302, the air outlet channel 302 is disconnected from the air inlet channel 301, the pilot head 300 is attached to the valve body 100, the air inlet 102 and the air outlet 103 are disconnected, the electromagnetic valve device 1 is in a closed state, and air cannot flow out of the air outlet 103.

Therefore, the air replenishing speed of the air inlet channel 301 to the air storage space is less than the air bleeding speed of the air outlet channel 302, so that the air pressure in the air storage space is lower than the air pressure around the pilot head 300 at the air inlet 102, and the pilot head 14 moves due to the pressure difference, thereby forming the air passing channel for communicating the air inlet 102 and the air outlet 103.
Of course, there is also a fitting clearance between the valve body 100 and the pilot head 300, the cross-sectional dimension of the fitting clearance is also smaller than that of the outlet throttle section 304, and the air intake amount of the fitting clearance can be approximately neglected.

Since the gas pressure of the pilot head 300 on the outlet 103 side is lower than the gas pressure of the pilot head 300 on the inlet 102 side, the pilot head 300 receives the pressure difference force between both sides and the spring force of the driving device 400, and the pilot head 300 is closely attached to the sealing tapered surface of the valve port portion 120.
When the electromagnetic valve device 1 is opened, the coil 210 is energized, due to the action of electromagnetic force, the iron core 220 overcomes the elastic force of the elastic member 230 and is separated from the air vent 305 on the pilot head 300, the high-pressure gas in the gas storage space is rapidly discharged to the air outlet 103 through the air outlet channel 302, and since the sectional size of the air inlet throttling section 303 is smaller than that of the air outlet throttling section 304, the gas supplying speed of the gas storage space is smaller than the gas discharging speed, so that the gas pressure in the gas storage space is lower than that of the air inlet 102, and the pilot head 300 is completely opened due to the pressure difference between two sides overcoming the acting force of the driving device 400.
When the electromagnetic valve device 1 needs to be closed, the coil 210 is powered off, the electromagnetic force disappears, the iron core 220 presses the air vent 305 on the pilot head 300 under the elastic force of the elastic member 230, the high-pressure gas supplies air to the air storage space through the air inlet channel 301, finally, the gas pressure in the air storage space is equal to the gas pressure of the pilot head 300 on the air inlet 102 side, and the pilot head 300 is closed due to the elastic force of the driving device 400.
