[0024] like Figure 4 As shown, the diverter assembly includes a connecting pipe 9 fixedly sleeved inside the intake pipe 3, the connecting pipe 9 passes through one side of the shell 1, and a diverter pipe 11 is fixedly sleeved on the outside, a return spring 12 is installed on the inner top of the connecting pipe 9, and a piston disk 10 is fixedly connected to the bottom of the return spring 12, and the natural gas pushes the piston disk 10 open, and in the process of pushing open, the spring is driven to contract upward, thereby allowing the natural gas to be output through the diverter pipe 11; the thickness of the piston disk 10 and the maximum compression stroke of the return spring 12 are less than the distance from the diverter pipe 11 to the connecting pipe 9.

[0025] like Figure 2 and Figure 3 As shown, a pressure sensor 22 is provided inside the air intake pipe 3, and a pressure gauge 6 is installed outside the shell 1. The pressure gauge 6 is electrically connected to the pressure sensor 22. A dial 8 is provided inside the pressure gauge 6, and a pointer 7 is installed at the inner center of the dial 8. When the pressure indicated by the pointer 7 on the inside of the pressure gauge 6 is unbalanced, leakage occurs at the joint between the air intake pipe 3 and the external natural gas pipeline, which can remind the operator to avoid unnecessary risks. A limiting groove 21 is provided on the outside of the shell 1, and a limiting block 14 is fixedly connected to the side of the movable seat 15 close to the limiting groove 21. The limiting block 14 is slidably connected to the limiting groove 21, so that when the movable seat 15 moves, the limiting block 14 at the bottom slides with the limiting groove 21 to increase the stability of the movement of the movable seat 15.

[0026] like Figure 1 and Figure 3 As shown, a threaded hole is provided inside the movable seat 15, and the movable seat 15 is threadedly matched with the screw rod 19. Through the adjusting disk 20, the adjusting disk 20 drives the screw rod 19 to rotate, so that the limit block 14 at the bottom of the movable seat 15 slides along the limit groove 21, and drives the connecting rod 17 and the mounting frame 4 at the top of the movable seat 15 to move the natural gas pipe together, so that the external gas transmission pipe and the air inlet pipe 3 are tightly sealed.

[0027] Working principle:

[0028] When the natural gas station flow distribution device is used, one end of the external natural gas pipeline is inserted into the air inlet pipe 3, so that the outside of the natural gas pipeline is abutted against the inside of the air inlet pipe 3, the connecting rod 17 is rotated to make the mounting frame 4 fit the outer wall of the natural gas pipeline, and the natural gas pipeline is fixed by the bolt 5 and the mounting frame 4, and then the adjusting disk 20 is used to drive the screw rod 19 to rotate, so that the limit block 14 at the bottom of the moving seat 15 slides along the limit groove 21, and the natural gas pipeline is driven to move by driving the connecting rod 17 and the mounting frame 4 at the top of the moving seat 15, so that the external gas pipeline is in contact with the air inlet pipe 3. The air pipe 3 is tightly sealed. When natural gas flows into the interior of the air intake pipe 3 from the external air supply pipe, the pressure sensor 22 is subjected to the pressure inside the air intake pipe 3 and is fed back through the pressure gauge 6 outside the shell 1, so that the operator can observe the internal pressure, so that the natural gas pushes the piston disc 10 open under pressure, and in the process of pushing open, the spring is driven to contract upward, so that the natural gas is output through the diversion pipe 11. When the pressure indicated by the pointer 7 on the inside of the pressure gauge 6 is unbalanced, leakage occurs at the joint between the air intake pipe 3 and the external natural gas supply pipe, which can remind the operator to avoid unnecessary risks.
