Title:
MULTI-PASSAGE REVERSING VALVE AND INTEGRATED MULTI-CHANNEL LIQUID PASSAGE MODULE
Document Type and Number:
WIPO Patent Application WO/2021/223332
Kind Code:
A1
Abstract:
A multi-passage reversing valve, comprising a valve body (21) and a plurality of liquid outlet pipes (28). The valve body (21) is provided with several layers of shunt passages (23); the shunt passages (23) comprise liquid inlet holes (231) and a plurality of shunt holes (232); the valve body (21) is internally provided with communication holes (233) enabling the shunt holes (232) to be connected to the liquid outlet pipes (28) in a one-to-one correspondence manner; the valve body (21) is provided with a control mechanism for respectively controlling the connection or disconnection between the shunt holes (232) and the communication holes (233); and the valve body (21) is provided with liquid inlet pipes (27) respectively communicated with the liquid inlet holes (231). The integrated multi-channel liquid passage module comprises a mounting base (1); the mounting base (1) is provided with sample pumps (4) matching the number of liquid outlet pipes (28); the liquid outlet pipes (28) are communicated with liquid inlets of the sample pumps (4); and liquid discharge pipes (41) are provided at the liquid outlets of the sample pumps (4). The liquid inlet pipes of the device can be connected to different reagents, and required reagents can be selectively discharged according to actual reagent demands, so that the number of pipes used by the liquid passage module is reduced, thus preventing flow blockage caused by folding of the connecting pipes in installation due to the excessive number of connecting pipes.
