Abstract
The invention relates to the technical field of valve equipment, in particular to a vertical liquid one-way valve. The vertical liquid one-way valve comprises a valve body vertically arranged, wherein a water inlet is formed in the upper end of the valve body; a water outlet is formed in the lower end of the valve body; a horizontally arranged baffle plate is arranged in the valve body; a through hole is formed in the baffle plate; an accommodating frame for accommodating a suspension ball is arranged at the bottom end of the baffle plate and below the through hole; the suspension ball is arranged in the accommodating frame; and the diameter of the suspension ball is larger than the aperture of the through hole. When liquid enters the valve body from the water inlet, the suspension ball cannot block the through hole under the effects of the weight of the suspension ball and the impact force of the liquid, so that the liquid can flow out from the water outlet after smoothly passing through the through hole; when the liquid flows back from the water outlet, the suspension ball can block the lower end of the through hole to stop the backflow of the liquid under the effect of the liquid on the buoyancy of the suspension ball; and the vertical liquid one-way valve is simple in whole structure and low in manufacturing cost.
