Novel sampling valve

The utility model discloses a novel sampling valve, which comprises a valve body, wherein a sampling channel communicated with a sampling pipeline is arranged on the valve body (2), a gland nut (3) and a connecting pipe (4) are arranged at the joint of the valve body (2) and a sampling pipe (6), the gland nut (3) and the connecting pipe (4) are connected in series and then welded to the sampling pipe (6), and the gland nut (3) is in detachably threaded connection with the valve body (2). The sampling operation of the sampling valve can be carried out once the valve body and the gland nut are connected in a threaded and sealed way; when not in use, the valve body and the gland nut can be detached to be placed or cleaned to be maintained independently, and therefore the operation and the cleaning maintenance of the sampling valve are extremely convenient. The sampling valve can sample the flowing liquid in the sampling pipe at random, thereby ensuring the authenticity of the sample, and is suitable for the samp
