One end of the connecting pipe 1 2 is connected to the air pipe of the air source through a connector 1 4, and the other end of the connecting pipe 1 2 is connected to the air inlet of the pressure regulating valve 1 through a connector 2 5. One end of the connecting pipe 2 3 is connected to the network pipeline of the spindle position through a connector 3 6, and the other end of the connecting pipe 2 3 is connected to the air outlet of the pressure regulating valve 1 through a connector 4 7.

[0024] The connecting pipe 2 includes a first pipe section 21 and a second pipe section 22. The diameter of the first pipe section 21 is smaller than the diameter of the second pipe section 22. The first pipe section 21 is connected to the second pipe section 22 through a reducing joint 8. The first pipe section 21 is connected to the pressure regulating valve 1, and the second pipe section 22 is connected to the gas pipe of the gas source.

[0025] One end of connector 4 is threaded to the gas pipe of the gas source, and the other end of connector 4 is interference-fitted to the outer peripheral wall of the second pipe section 22.

[0026] One end of connector 25 is threaded to the air inlet of pressure regulating valve 1, and the other end of connector 25 is interference-fitted to the outer peripheral wall of the first pipe section 21.

[0027] One end of connector 36 is threaded to the network pipe of the spindle position, and the other end of connector 36 is interference-fitted to the outer peripheral wall of connecting pipe 23.

[0028] Connector 47 is L-shaped. One end of connector 47 is threaded to the outlet end of pressure regulating valve 1, and the other end of connector 47 is interference-fitted to the outer peripheral wall of connecting pipe 2 3.

[0029] First, assemble the regulating valve, connecting pipe 1, and connecting pipe 2. Then, connect the gas pipe to the air source through connector 1, and connect the network pipeline of the spindle position through connector 3, and adjust the pressure of the regulating valve 1 to the value required for production. This allows for the adjustment of the network pressure of a single spindle position. The network air pressure can be adjusted at any time on any machine and at any spindle position according to actual production needs.
