[0005] The technical scheme of the utility model is:

[0006] A solution pipeline selection device comprises an inner core 1 and an outer shell 2.

[0007] The inner core 1 is a branched pipeline structure composed of an inlet pipe 11 and an outlet pipe 12, the number of inlet pipes 11 is 1 to 5, and the number of outlet pipes 12 is 2 to 10. The material of the inner core 1 is soft, tough and corrosion-resistant plastic, such as polyethylene (PE) and polyvinyl chloride (PVC).

[0008] The outer shell 2 covers the outer surface of the inner core 1 and plays a protective, supporting and shaping role. The material of the outer shell 2 is hard and corrosion-resistant metal, such as stainless steel. The outer shell 2 can be opened to facilitate replacement of the inner core 1, and the outer shell 2 has a fixing device 21 to fix the outer shell, which is a screw or a buckle.

[0009] The outer end of the inlet pipe 11 has an inlet interface 13, and the outer end of the outlet pipe 12 has an outlet interface 14.

[0010] There is a suspension beam 3 above each of the inlet pipe 11 and the outlet pipe 12, which is fixed to the outer shell 2 by a spring and can be pressed down under external pressure to block the flow of liquid in the inlet pipe 11 or the outlet pipe 12; the spring rebounds under the action of the spring after the external pressure is removed.

[0011] The utility model discloses a kind of solution pipeline selection devices, which can be used as the parts of automatic liquid distribution system, and the use method is as follows:

[0012] Liquid inlet interface 13 and liquid outlet interface 14 are connected with different solution storage tanks through pipeline respectively, and the mechanical device in the automatic liquid distribution system sequentially presses different hanging chisel 3 under the control of program to determine the opening / closing state of each liquid inlet pipe 11 and liquid outlet pipe 12, so as to realize the selection and switching of liquid passage.

[0013] The utility model has the advantages that selective communication or closing of different solution pipelines can be realized, and the inner core is replaceable, so that one device can be used for research or production of different drugs, and the automation control of recombinant protein drug research and production process is facilitated.
