the regulated air source enters the position of the second end cover 7 of the first air cylinder 1 through the air control valve assembly 10, so that the air source drives the first piston 2 to move leftwards, the first piston 2 leaves the surface of the second end cover 7, the signal switch assembly 13 pressed by the first piston 2 is changed from a closed state to an open state, and meanwhile, the air source is introduced into the left end of the valve rod 104 through the first flow channel 1011 and the second flow channel 1013 in the air control valve assembly 10, and the left end area of the valve rod 104 is larger than the right end area, so that the valve rod 104 is pushed to move rightwards; when the first piston 2 moves to the first end cover 6, the signal switch assembly 13 on the first end cover 6 is pressed, so that the signal switch assembly 13 on the first end cover 6 is changed from an open state to a closed state, at the moment, no air source is supplied to the left side of the valve rod 104 in the air control valve assembly 10, and because the signal switch assembly 13 of the second end cover 7 is opened, residual air overflows through the flow passage air hole 1012 to reduce the pressure on the left side of the valve rod 104, and the valve rod 104 is pushed to move leftwards, so that reciprocating pressurization is completed; when the medium to be pressurized enters the one-way valve assembly 27 from top to bottom, the second return spring 276 deforms to drive the stainless steel ball valve core 275 to move downwards, so that the stainless steel ball valve core 275 and the stop 273 generate a channel through which the medium can enter the second cylinder 8 and the third cylinder 9, and when the medium enters the one-way valve assembly 27 from bottom to top, the second return spring 276 extrudes the stainless steel ball valve core 275, so that the contact between the stainless steel ball valve core 275 and the stop 273 is tighter, and therefore, the medium cannot pass from bottom to top, and the medium can only flow along a single direction.
