The inner circle of the valve body end cover 8 is provided with a valve body end cover inner sealing ring 20 to ensure the sealing with the outer circumference of the piston cylinder 7. The whole valve body 9 is arranged on the base 3 through a fixing plate 10, and an air inlet and outlet 19 is processed on the valve body end cover 8.

At this time, the solenoid valve 24 at the lower part of the cylinder 25 is opened, so that the components in the cylinder 25 are introduced into the valve body 9 through the feed connector 27 mounted on the valve body 9 along the passage of the solenoid valve 24 and the cylinder blanking connector 23 and the pipe 22 thereunder.

At this time, the components inside the valve body 9 are transferred to the outside through the discharge port 13. It is noted here that the inlet is directed downwards so that the components in the pipe 22 no longer flow into the valve body 9 after the solenoid valve 24 below the cylinder 25 has been closed.
