Reversible self-cleaning one-way valve

The utility model relates to a reversible self-cleaning one-way valve which comprises a shell, a first feeding port, a second feeding port, a discharging port and a one-way valve body, the first feeding port, the second feeding port and the discharging port are formed in the shell, the one-way valve body is rotatably arranged in the shell, and the internal structure of the one-way valve can be reversed and cleaned through a simple rotary reversing mechanism. Therefore, the experimental device is prevented from being integrally disassembled and assembled when the one-way valve is cleaned, the one-way valve can be cleaned while the experimental feeding connecting pipeline is replaced, and the experimental efficiency is greatly improved. 本实用新型涉及一种可换向自清洁单向阀，包括壳体以及设置在壳体上的第一进料口、第二进料口和出料口，和可旋转设置在壳体内的单向阀主体，通过简单的旋转换向机构使单向阀内部结构能够实现换向清洁，从而在避免在单向阀清洁时整体拆装实验装置，还可以实现单向阀清洁同时更换实验进料连接管路，从而大幅提高实验效率。
