Title:
VALVE ASSEMBLY CAPABLE OF CONTROLLING FLOW DIRECTION OF FLUID
Document Type and Number:
WIPO Patent Application WO/2019/189981
Kind Code:
A1
Abstract:
The present invention proposes a valve assembly capable of controlling a fluid to flow only in one direction along an inclined direction. A valve body (10) of the valve assembly of the present invention comprises: a partition wall (14) having a through-hole (14a) formed therethrough and partitioning the inside of the body into a first inner passage (18a) and a second inner passage (18b); a first entrance/exit (12a) for supplying a fluid in the first inner passage to the outside or supplying an external fluid to the first inner passage; and a second entrance/exit (12b) for supplying a fluid in the second inner passage to the outside or supplying an external fluid to the second inner passage. In addition, a first check roller (11a) and a second check valve (11b) are brought into close contact with or spaced apart from the through-hole (14a) by buoyancy or sinking force along the inclined direction of the valve body, and thus controls the flow direction of a fluid in one direction. Further, when any one check roller is brought into contact with the through-hole of the partition wall, the check roller is designed to protrude up to the inner passage at the opposite side through the through-hole of the partition wall.
