[0016] like Figure 1-2 As shown, the novel spray atomizing gas control valve comprises a valve body 1, wherein the valve body 1 is provided with a valve cavity, an air inlet channel 2 and an air outlet channel 3, wherein one end of the air inlet channel 2 forms an air inlet 4 on the surface of the valve body 1, and one end of the air outlet channel 3 forms an air outlet 5 on the surface of the valve body 1, wherein a valve core is installed in the valve cavity, wherein the valve cavity comprises a bottom cavity 6, a transition cavity 7 and a top cavity 8 which are connected in sequence, wherein the top cavity 8 forms a control air port 9 on the surface of the valve body 1, and the valve core comprises a pressing plate 10, a blocking plate 11, a spring 12 and a connecting plate 13. The rod 13 and the pressure plate 10 are installed in the top cavity 8, the plugging plate 11 and the spring 12 are located in the bottom cavity 6, the inner diameter of the transition cavity 7 is smaller than the inner diameter of the bottom cavity 6 and the inner diameter of the top cavity 8, the diameter of the plugging plate 11 is larger than the inner diameter of the transition cavity 7, the spring 12 presses the plugging plate 11 toward the transition cavity 7, the connecting rod 13 is located in the transition cavity 7, the upper end of the connecting rod 13 is fixedly connected to the pressure plate 10, and the lower end of the connecting rod 13 is fixedly connected to the plugging plate 11, the bottom cavity 6 is connected to the air inlet channel 2, and the transition cavity 7 is connected to the air outlet channel 3. The atomized gas enters the air inlet channel 2 from the air inlet 4, and then enters the bottom cavity 6. Due to the action of the spring 12 and the atomized gas, the plugging plate 11 blocks the connection between the transition cavity 7 and the bottom cavity 6, and the atomized gas cannot enter the transition cavity 7. The control gas is connected to the control gas port 9, and the control gas presses the pressure plate 10, and the connecting rod 13 drives the blocking plate 11 to overcome the elastic force of the spring 12 to move, so that the transition chamber 7 and the bottom chamber 6 are connected, so that the atomized gas enters the transition chamber 7, and then passes through the gas outlet channel 3 and is discharged from the gas outlet 5. The gas outlet 5 is then connected to the nozzle through the corresponding pipeline to provide the nozzle with atomized gas.

The upper sealing ring 16 and the lower sealing ring 15 prevent the leakage of the atomized gas. When the pressing plate 10 moves up and down, the exhaust channel 17 provides an exhaust and suction channel for the air in the top chamber 8, so that the pressing plate 10 can be pressed smoothly.

[0018] Furthermore, the exhaust ports 18 are respectively connected with guide pipes 19. The guide pipes 19 guide the exhausted gas to prevent it from affecting surrounding equipment components.
