    摘要： Water-cooling U-valve is composed of a downcomer (1), a riser (2), and a return chute (3), which are sequentially connected. An intermediate partition (4) is disposed between the downcomer (1) and the riser (2), the lower parts of which are interconnected. A material returning partition (5) is disposed between the riser (2) and the return chute (3), the upper parts of which are interconnected. The casing of U-valve is membrane walls, the inside of which are laid with refractory. Some water-cooling tubes of the membrane walls extend into the inside of the U-valve, forming the water cooing intermediate partition (4) and material returning partition (5). There are headers (40, 50) for both the intermediate partition (4) and the material returning partition (5), and the headers (40, 50) are connected with the headers (33, 13) formed by some water-cooling tubes of membrane walls by connecting tubes (7, 8). The invented U-valve can guarantee that there is no expansion difference between the partitions and the casing, which can extend the working life of the partitions and realize the long-term safe and stable operation of the U-valve.
