Drainage starting mechanism of button drainage valve

LIU YONGMAO / ZHANG ZIPENG

The invention discloses a drainage starting mechanism of a button drainage valve. The drainage starting mechanism is installed on a drainage valve body; the dropping stroke of a lower pipe in the drainage valve body is controlled by a half-drainage float bucket and a full-drainage float bucket, and then the half drainage and the full drainage can be achieved; a half-drainage pulling component comprises a half-drainage pushing rod and a stopping part, the half-drainage pushing rod is movably installed on a half-drainage button, the half-drainage pushing rod is in a free state, and the lower end of the half-drainage pushing rod is away from a clamping connecting piece of an inner core pipe; the stopping part is arranged on a full-drainage button and arranged under the other end of the half-drainage pushing rod; otherwise, the half-drainage pushing rod is movably installed on the full-drainage button, the half-drainage pushing rod is in the free state, and the lower end of the half-drainage pushing rod is away from the clamping connecting piece of the inner core pipe; the stopping piece is arranged on the half-drainage button and arranged on the other end of the half-drainage pushing rod. When the full-drainage button is pressed independently, the full-drainage water draining is achieved, moreover, when the half-drainage button and the full-drainage button are pressed simultaneously, the full-drainage water draining can also be achieved, the full-drainage water draining chosen by a plurality of modes is achieved, and the choice of the full-drainage water draining is simpler and more convenient.
