AI Technical Summary
The float device inside the water tank is prone to deformation and breakage due to large fluctuations in the liquid level. Furthermore, the valve stem is not strong enough and lacks sufficient resistance to bending, causing the float to malfunction and resulting in waste.
The valve stem employs various designs, including a straight stem with a support rod, a flexible helical blade, and a central stem, to enhance the strength of the valve stem. Threaded connections facilitate the connection between the valve stem, the rotating rod, and the float ball, making installation and disassembly convenient.
It improves the valve stem's resistance to deformation and bending, prevents breakage, extends its service life, adapts to various water tank environments, and avoids the waste of float balls.
