The working principle and the using flow of the invention are as follows: the water flows from the two flow channels 101 into the first pipeline 1, under the action of water pressure, the first sealing plate 112 and the second sealing plate 113 are respectively bent inwards along the central axis of the rotating rod 104 by an angle, and are respectively stressed by the elastic tension of the torsion spring 114, the two tail ends of the torsion spring 114 respectively prop against the side ends of the first sealing plate 112 and the second sealing plate 113, so that the first sealing plate 112 and the second sealing plate 113 keep a horizontal state, the first sealing plate 112 and the second sealing plate 113 respectively block the two flow channels 101 after the water flow weakens or disappears, thereby the first pipeline 1 is in a closed state, the water flow is prevented from flowing back from the opposite direction, when the parts of the one-way valve mechanism are damaged, the motor 109 drives the gear 111 to rotate through the external connection signal, the gear 111 is meshed with the rack 106, and therefore the second sliding block 105 is driven to slide on the inner wall of the sliding chute 102, thereby drive bull stick 104 and remove two passageway 101 are kept away from to first shrouding 112 and second shrouding 113, can open the passageway of two passageway 101 to first pipeline 1 direction completely this moment, and touch stopper 107 after removing certain distance and be static completely, prevent that the excessive displacement of bull stick 104 from touching gear 111, under the multiple closed condition of needs, start telescopic machine 207, telescopic machine 207's output shaft drives snubber block 208 and moves down, the effect of snubber block 208's elasticity tension makes the decline process of third shrouding 209 comparatively steady, insert the clearance between first connecting block 2 and the second connecting block 3 after the third shrouding 209 passes groove 204, the interval of first connecting block 2 and second connecting block 3 is the same with the thickness of third shrouding 209, and then the bottom of third shrouding 209 is contradicted to bottom plate 201 department can be sealed completely with the passageway of first connecting block 2 and second connecting block 3.
Finally, it should be noted that: the above is only a preferred embodiment of the present invention, and the present invention is not limited thereto, but it is to be understood that the present invention is described in detail with reference to the foregoing embodiments, and modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
