Title:
VALVE ASSEMBLY CAPABLE OF CONTROLLING FLOW DIRECTION OF FLUID ACCORDING TO SLOPE DIRECTION
Document Type and Number:
WIPO Patent Application WO/2018/221773
Kind Code:
A1
Abstract:
The present invention proposes a valve assembly in which a flow direction of fluid is controlled according to a slope angle and a large amount of fluid can be moved. A valve body (10) of the valve assembly of the present invention comprises: a pair of inlet/outlets (12, 14) in which an internal path (18) through which fluid can pass is provided, which are formed at positions facing each other, respectively, through which fluid can flow in and out, and which is formed to be relatively long in the horizontal direction than the vertical direction; and a plurality of roller seating portions (13, 15) which are formed in inner portions of inlet/outlets, respectively. In addition, the valve body is provided with a plurality of connecting portions (17A, 17B) which communicate with the pair of inlet/outlets and connect so that fluid can flow between an inside and an outside of the valve body. In addition, opening and closing rollers (16A, 16B) control the flow of the fluid from the inside of the valve body to the connecting portion by being seated on or separated from the roller seating portion by buoyant force according to a slope of the valve body. The opening and closing rollers (16A and 16B) are prevented from moving to the roller seating portion on the other side by flowing only within a predetermined range due to the stopper (19).
