MINOR WATER LEAK PREVENTION APPARATUS FOR WATER INLET VALVE
A minor water leak prevention apparatus for a water inlet valve. Said apparatus is arranged on a water inlet valve body (1) and comprises a swing arm (2), and regulation bar (3), a float (4), a water container (5), a siphon tube (6), and a counterweight buoyancy switch (7). The swing arm (2) is pivotably connected to the water inlet valve body (1). One end of said arm (2) is provided with a back pressure pad (21) aligned with a back pressure hole (11) in the water inlet valve body (1), and the other end of the swing arm (2) is connected to the regulation bar (3). The float (4) is disposed on the regulation bar (3) and within the water container (5), said water container (5) being disposed on the water inlet valve body (1). A siphon tube (6) is disposed on the water container (5), said tube (6) having an air aperture (63) formed thereon. The counterweight buoyance switch (7) is disposed on the water container (5), said switch (7) comprising a counterweight water compartment (71) and a buoyance water compartment (72), which are mutually independent. The bottom end of said counterweight water compartment (71) is provided with a water drain hole (711), and the top end of said counterweight water compartment (71) is provided with a closure pressing plate (712), said cap (712) being aligned with the air aperture (63). The counterweight buoyance switch (7) controls the opening and closing of the air aperture (63), such that when a minor water leak occurs in the water tank, the water inlet valve immediately stops letting water in, thus saving water resources.
