when the electric telescopic rod stretches, a valve core liquid outlet on the valve core, a second driven semicircular seal and a second driving semicircular seal extend out of the valve body through valve core liquid outlet through holes, and a second driven semicircular seal gear, a second driving semicircular seal gear and a third gear extend out of the valve body through seal gears on the valve bottom through holes; the bump and the groove are made of a pair of magnets; the electric telescopic rod is fixed on the outer wall of the valve body through the first fixing seat and the second fixing seat; the valve bottom is also provided with a first valve core rod through hole and a second valve core rod through hole, and the valve core rod on the valve core is connected with the electric telescopic rod after passing through the first valve core rod through hole and the second valve core rod through hole;
the method comprises the following steps:
step 1: in an initial state, the first driven semicircular seal is closed with the first driving semicircular seal, the second driven semicircular seal is closed with the second driving semicircular seal, the electric telescopic rod is in a contracted state, the valve core is positioned above the inner part of the valve body, and the valve body is connected with the liquid inlet pipeline through the flange interface;
step 2: the liquid inlet control motor converts the first driven semicircular seal and the first driving semicircular seal from a closed state to an open state through a series of gear transmission, and liquid enters the interior of the quantitative valve through the liquid inlet of the valve body and the liquid outlet of the valve body;
step 3: the first driven semicircular seal and the first driving semicircular seal are kept in an open state, the electric telescopic rod starts to stretch to drive a valve core connected with the electric telescopic rod to move downwards, a valve core liquid outlet on the valve core, the second driven semicircular seal and the second driving semicircular seal extend out of the valve body through valve core liquid outlet through holes, a second driven semicircular seal gear, a second driving semicircular seal gear and a third gear extend out of the valve body through seal gears on the valve bottom through holes, when the electric telescopic rod stretches completely, the second gear is meshed with the third gear, and the liquid inlet control motor controls the first driven semicircular seal and the first driving semicircular seal to be switched from the open state to the closed state; the liquid volume quantitatively discharged by the quantitative valve is the liquid volume contained in the space between the lower part of the first driven semicircular seal and the first driving semicircular seal and the upper part of the second driven semicircular seal and the second driving semicircular seal;
step 4: the liquid outlet control motor controls the opening of the second driven semicircular seal and the second driving semicircular seal through a series of gear transmission, and discharges liquid in the valve body; after the liquid in the valve is discharged completely, the liquid outlet control motor controls the second driven semicircular seal and the second driving semicircular seal to be closed, and the electric telescopic rod contracts the valve core to return to the original state.
