10. A method of operating an outdoor non-blocking vacuum sewage valve as set forth in any one of claims 1-9, further comprising the steps of:
s1: when an air inlet (301) of the valve cover (3) is communicated with the vacuum pump through a vacuum pipe (16), an internal cavity formed by the rubber cylinder (5) and the valve cover (3) is negative pressure, the rubber cylinder (5) contracts and deforms under the action of the negative pressure to move upwards, the elastic telescopic rod (4) is compressed and drives the valve clack (6) to move upwards, at the moment, the flow channels (101) at the two sides of the valve seat (1) are communicated through the vertical cavity (102), and the valve is opened;
s2: the sewage flows from a runner (101) at one end of the valve seat (1) to a runner (101) at the other end, in the process, the telescopic ends of the electric telescopic rods (8) are controlled to reciprocate and stretch, the electric telescopic rods (8) at two sides of the runner (101) drive the cutting plates (801) at two sides to be close to each other to cut sundries in the sewage in the flowing process, and when the electric telescopic rods (8) shrink, the cutting plates (801) are driven to reset to enable the cutting surface at the other side of the cutting plates (801) to be propped against the reinforcing plates (802), so that sundries between the reinforcing plates (802) and the cutting plates (801) are cut;
s3: when the electric telescopic rod (8) stretches, the telescopic end of the electric telescopic rod (8) pulls the scraping ring (9) to slide on the inner wall of the runner (101) through the pull rope (901), and when the electric telescopic rod (8) contracts, the elastic element (111) pulls the scraping ring (9) to move back in the runner (101), so that the scraping ring (9) scrapes sundries possibly adhered in the runner (101);
s4: the sundries scraped by the scraping ring (9) are partially adhered to the scraping surfaces at two sides of the scraping ring (9), the direction of the scraping ring (9) facing the sewage is set to be a conical guide surface, and the diameter of the conical guide surface is smaller than that of the runner (101), so that when the sewage flows to the conical guide surface, the water flow speed is increased, and the water flow impact force is increased to wash the impurities remained on the conical guide surface;
s5: an exhaust hole (902) is formed in one side, away from the conical flow guide surface, of the scraping ring (9), when the sliding rod (112) drives the piston (11) to reciprocate in the sleeve (10), the piston (11) moves rightwards to enable the space of the first cavity to be reduced, the space of the second cavity to be enlarged, external air is extracted through the air inlet valve, and the piston (11) sequentially guides the air in the first cavity into the air guide groove (12) and the pneumatic cavity (13) through the first exhaust valve (121) and discharges the air through the exhaust hole (902); the piston (11) moves leftwards to enable the first cavity space to be enlarged, external air is extracted through the air inlet valve, the second cavity space to be reduced, and the piston (11) sequentially guides air in the second cavity into the air guide groove (12) and the pneumatic cavity (13) through the second exhaust valve (122) and discharges the air through the exhaust hole (902); the air discharged from the exhaust hole (902) can blow off impurities remained on the side of the scraping ring (9), and on the other hand, the air is mixed into sewage to form a gas-liquid two-phase mixture, so that the possibility of adhesion and deposition of solid matters on the runner (101) is reduced;
s6: when the air inlet (301) is not communicated with the vacuum pump any more, the pressure is released instantly by the inner cavity formed by the rubber air cylinder (5) and the valve cover (3), the elastic telescopic rod (4) is reset through self elastic force, meanwhile, the rubber air cylinder (5) is driven to reset, and meanwhile, the valve clack (6) is driven to move downwards when the rubber air cylinder (5) is reset, so that the groove (602) on the valve clack (6) is matched with the sealing ribs (1021) on the valve seat (1) to form sealing, thereby the flow channels (101) on the two sides of the valve seat (1) are separated, and the valve is closed.
