The purpose of the present invention is to provide a sampling valve that can carry out daily and periodic management, simply and without trouble. A sampling valve (10) comprises: a sampling housing (30) that is fixed to a pipe (1) in which a liquid flows; and a water communication part (40) that is installed inside the sampling housing (30) and that has a water communication path (41) for extracting a sampling liquid from the pipe (1). In conjunction with the movement of a sampling socket (50), the water communication part (40) moves in the axial direction inside the sampling housing (30), thereby opening and closing the water communication path (41). The water communication part (40) is formed of a material which allows ultraviolet light to pass therethrough, and below the water communication part (40) a light source (20) which emits ultraviolet light is disposed. Microorganisms in the processing water which remains in the valve (10) after water sampling are killed by the ultraviolet light emitted from the light source (20). In conjunction with the water sampling operation for removing liquid, water sampling detection information is automatically output, and as result, the water sampling detection information can be recorded to a recording device such as a computer, as water sampling history. |
