Sequential injection urinary iodine determination multi-passage 16-hole selector valve

Disclosed is a sequential injection urinary iodine determination multi-passage 16-hole selector valve. At present, the known sequential injection valve generally utilizes a six-way valve, when having more liquid inlet components, the sequential injection valve is messed in pipeline distribution and complex in operation and affects experimental accuracy, repeatability and speed, and further, the six-way valve is single in function and can not meet more and more using requirements. The sequential injection urinary iodine determination multi-passage 16-hole selector valve comprises a center shaft (1), the center shaft penetrates through center holes of a stator fixing ring (2), a stator (3), a rotor (4) and a rotary handle (5), the stator fixing ring (2) is connected with the stator (3), the stator (3) is connected with the rotor (4), the rotor (4) is connected with the rotary handle (5), and the center shaft (1), the stator fixing ring (2) and the rotary handle (5) are fixed via bolts (6).
