PURPOSE: A water level regulating valve using a hub link for low water level is provided to easily regulate the water level of a water tank by regulating the height of a buoyancy member with the hub link. CONSTITUTION: A water level regulating valve comprises a spool valve(200), a connection member(300), a fastening part(400), a support member(500), a hub link(600), and a regulating member(700). A sealing member is installed in the spool valve to control the movement of the fluid. The connection member is connected to the sealing member of the spool valve to guide the vertical movement of the sealing member. One end of the connection member is rotatably fastened to one side of the exterior of the fastening part. One end of the fastening part is rotatably fastened to one side of the exterior of the spool valve. One end of the support member is connected to the other end of the fastening part and is extended from the fastening part at a predetermined length. The hub link comprises a first connection part having a first coupling hole to fasten the other end of the support member; and a second connection part having a second coupling hole. The regulating member is inserted in the second coupling hole of the hub link. A buoyancy member(800) is installed in one end of the regulating member. |
