Document Type and Number:
WIPO Patent Application WO/2022/199272
Kind Code:
A1
Abstract:
A control valve (2) for controlling fluid transmission. The control valve comprises a valve body (20), in which a first channel (21) and a second channel (22), which are independent of each other, are defined, wherein the control valve (2) is configured to control opening and closing of the first channel (21) or the second channel (22); a first inlet (211) and a first outlet (212), which are in fluid communication with the first channel (21); and a second inlet (221) and a second outlet (222), which are in fluid communication with the second channel (22). The first inlet (211), the first outlet (212), the second inlet (221) and the second outlet (222) are basically at the same height, such that the height of the control valve (2) can be effectively reduced, thereby reducing an installation space of the control valve (2), and making the control valve more convenient to install.
