Flip type drain valve and drain valve control method
The invention relates to a flip type drain valve. The flip type drain valve comprises a water-stop floating barrel, an outer cover, a drain component and a ventilating check valve. The water-stop floating barrel is movably connected to the outer cover. The drain component penetrates the water-stop floating barrel to be movably connected to the outer cover. A cavity is formed by the water-stop floating barrel, the outer cover and the ventilating check valve in a surrounding manner. Negative pressure in the cavity is controlled through control of opening and closing of the ventilating check valve, and descending and ascending of the water-stop floating barrel is further controlled to achieve water drainage of the drain valve. A drain valve control method includes that the cavity is formed by the water-stop floating barrel, the outer cover and the ventilating check valve in a surrounding manner, the negative pressure is formed in the cavity after water in the cavity is drained, and the water-stop floating barrel is controlled to ascend to open the drain valve; the ventilating check valve is opened to release the negative pressure in the cavity, and the water-stop floating barrel descends under the acting force of dead weight to close the drain valve. The drain valve can drain water by flipping, and control of water drainage volume is reliable and simple.
