Title:
MAIN CONTROL VALVE, AND MULTI-TANK CONTROL VALVE BANK COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2021/244169
Kind Code:
A1
Abstract:
Disclosed are a main control valve and a multi-tank control valve bank comprising same. The main control valve is provided with a water intake cavity (111), a water output cavity (112) and an ejector (20). A surface of the main control valve is provided with a water inlet (1) and a water outlet (2), the water inlet (1) being in communication with the water intake cavity (111), and the water outlet (2) being in communication with the water output cavity (112); and the surface of the main control valve is further provided with: at least one first flow-dividing port (114), with the first flow-dividing port (114) being in communication with the water intake cavity (111); at least one second flow-dividing port (115), with the second flow-dividing port (115) being in communication with the water output cavity (112); and at least one third flow-dividing port (116), with the third flow-dividing port (116) being in communication with a water output end of the ejector (20). By means of arranging the flow-dividing ports in the water intake cavity (111) and the water output cavity (112) of the main control valve, the water inlet (1) and the water outlet (2) of the main control valve are shared and correspondingly connected to other valve bodies, such that multi-tank control and water production are achieved, without it being necessary to arrange additional flow-dividing devices and pipelines outside the valve bodies, thus simplifying the structure. The third flow-dividing port (116) is provided in the water output end of the ejector (20) and used for connecting the main control valve to salt liquid inlets (113) of other valve bodies, such that the sharing of the ejector (20) is achieved, and the structure of a valve body is simplified.
