step three, limiting, namely driving the telescopic rod (502) to stretch and slide by the operation of the electric cylinder (501) so as to drive the limiting ring (504) to vertically slide along the sliding rail (503) and further drive the limiting plate (505) to vertically move, 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 airflow speed flowing into the cavity of the positive and negative integrated multifunctional pump through the vertical hole (3) can be adjusted;
step four, closing, namely pressing the blades (403) under the action of the air pressure in the chamber and restoring the blades to a plane state from a tilting state when the air pressure in the chamber is larger than the external air pressure without air supplement, so that the outer wall of the bottom surface of the sealing gasket (404) can be driven to extend to the primary sealing circulation hole (10) in the groove (9);
step five, sealing, namely operating an electric cylinder (501) to drive a telescopic rod (502) to slide in a telescopic manner so as to drive a limiting ring (504) to vertically slide along a sliding rail (503), and further driving a limiting plate (505) to vertically move and attach to the upper surface of a blade (403), so that a sealing gasket (404) can be completely attached to the inside of the groove (9), and further sealing of the convection through hole (10) is completed;
step six, maintenance, namely, the external screw is rotated along the threaded hole (11) and is screwed out from the inside of the threaded groove (13), so that the partition plate (8) and the outer wall of the bottom surface of the support plate (2) can be separated, the clamping groove (12) and the outer side wall of the convex block (14) can be slid, the pipe body (1) can be taken out, and the convection through hole (10) can be cleared and the inside of the pipe body (1) can be maintained.
