8. The method for using the positive pressure air supplementing device for the positive and negative integrated multifunctional pump according to any one of claims 1 to 7 is characterized by comprising the following steps:
firstly, mounting, namely firstly inserting the pipe body (1) into the inner side wall of the positive and negative integrated multifunctional pump chamber along the lower end of the pipe body (1), then clamping the pipe body (1) with the inner side wall of the positive and negative integrated multifunctional pump chamber along the connecting plate (6), and then rotating an external fastening piece along the connecting hole (7) so as to detachably connect the connecting plate (6) with the inner side wall of the positive and negative integrated multifunctional pump chamber, thereby mounting the device in the positive and negative integrated multifunctional pump chamber;
when the internal air pressure of the positive and negative integrated multifunctional pump cavity is smaller than the external air pressure and air needs to be supplemented, external air flow enters along the flow holes (10) and ejects the sealing gasket (404) from the inside of the groove (9), then the blades (403) are rotated and tilted along the rotating shafts (402) on the outer side walls of the side blocks (401), and the air flow flowing in through the flow holes (10) penetrates through the vertical holes (3) to enter the positive and negative integrated multifunctional pump cavity for air supplementing operation;
step three, limiting, namely driving the telescopic rod (502) to slide in a telescopic way through the operation of the electric cylinder (501) so as to drive the limiting ring (504) to slide vertically along the sliding rail (503), and further driving the limiting plate (505) to move vertically, so that the maximum opening and closing angle of the blade (403) can be limited under the action of the vertical movement of the limiting plate (505), and the air flow rate flowing into the positive and negative integrated multifunctional pump cavity through the vertical hole (3) can be regulated;
step four, closing, when the internal air pressure of the positive and negative integrated multifunctional pump cavity is larger than the external air pressure and no air supplement is needed, then pressing the blades (403) under the action of the internal air pressure of the cavity and enabling the blades to recover to a plane state from a tilted state, so that the outer wall of the bottom surface of the sealing gasket (404) can be driven to extend to the inside of the groove (9) to preliminarily seal the flow hole (10);
step five, sealing, namely driving the telescopic rod (502) to slide in a telescopic way through the operation of the electric cylinder (501) so as to drive the limiting ring (504) to slide vertically along the sliding rail (503), and further driving the limiting plate (505) to move vertically and be attached to the upper surface of the blade (403), so that the sealing gasket (404) can be completely attached to the inside of the groove (9), and further sealing the convection through hole (10) is completed;
step six, maintenance is carried out, namely, the external screw is rotated along the threaded hole (11) and screwed out from the inside of the threaded groove (13), so that the partition plate (8) can be separated from the outer wall of the bottom surface of the supporting plate (2), and further the clamping groove (12) and the outer side wall of the protruding block (14) can slide and take out the pipe body (1), and therefore the blockage of the through hole (10) can be removed and the maintenance can be carried out on the inside of the pipe body (1).
