More Information
Summary:The invention relates to a floating ball type one-way drainage valve which is capable of preventing stored water leakage and discharging ground water in time and is applicable to a slope or a retaining wall of hydraulic engineering. The floating ball type one-way drainage valve consists of an upper valve body, a lower valve body, a floating ball and a drainage pipe, wherein the upper valve body has a funnel shape, a smooth camber neck part, and a top part connected with the drainage pipe, the lower valve body has a cylindrical shape and a bottom part connected with the drainage pipe, the floating ball is a hollow ball and has a straight bar attached onto the surface, and the upper valve body and the lower valve body are connected with each other through screws. The floating ball moves up and down in the valve body, and the straight bar stirs the sludgy on the bottom part of the valve body to prevent blockage. The upper and lower valve bodies share the same diameter, the diameter of the drainage pipe is smalle
