ABSTRACT:
A valve for controlling the level of fluids in basins, such as stands for cut trees, aquariums, or hydroponic plant basins. The valve 6 includes a rigid fluid conduit 26 passing through the wall of a float chamber 16, in order to transmit fluid into a flexible tubing 28 connected to the portion of the rigid fluid conduit 26 inside the float chamber 16. In the valve's open position, the flexible tubing 28 is maintained in a partially bent postion, riding on the upper end of a float 30 contained within the float chamber 16. As the fluid enters the float chamber 16, and exits into basin 8, the fluid level rises causing the float 30 to rise in float chamber 16. The rising float further bends the flexible tubing 28, causing it to collapse and block the flow of fluid therethrough. As the fluid in basin 8 falls, the flexible tubing 28 returns to its original position, and the flow of fluid through the valve resumes.
