The piston type water inlet valve comprises a water inlet channel (11) arranged in a water inlet body (10), a water stopping piston (13) arranged at a water outlet (12) of the water inlet channel (11), a buoyancy component (20) and a lifting rod (30), wherein the buoyancy component (20) applies buoyancy in a first direction to one end of the lifting rod (30) so that the other end of the lifting rod (30) applies force in a second direction to the water stopping piston (13), the force in the first direction is upward force, and the force in the second direction is downward pressure; the method is characterized in that: the water stop device further comprises a water branch channel (40), wherein the water pressure of the water branch channel (40) applies the assistance in the second direction to the water stop piston (13) through an assistance component, and the water stop piston (13) overcomes the water inlet pressure of the water inlet channel (11) to close the water outlet (12) under the assistance of the buoyancy component (20) and the water pressure of the water branch channel (40); the water stop device further comprises a power-assisted lever (50), wherein the power-assisted assembly pushes one end of the power-assisted lever (50) towards the first direction, so that the other end of the power-assisted lever (50) exerts power assistance on the water stop piston (13) in the second direction;
the moment arm of force of the water inlet pressure F1 of the water inlet channel (11) acting on the assisting lever (50) is L1', the moment arm of force of the water pressure assisting F2 of the branch waterway (40) acting on the assisting lever (50) is L2, and the moment of the water inlet pressure F1 of the water inlet channel (11) is larger than the moment of the water pressure assisting F2 of the branch waterway (40), namely: f1×l1' > f2×l2.
6. A piston feed valve as set forth in claim 5 wherein: the booster lever (50) is arranged at an angle in the horizontal direction relative to the lifting lever (30).
7. A piston feed valve as in claim 1, 2, 3, 4 or 6 wherein: the buoyancy assembly (20) comprises a float (21), wherein the float (21) floats along with the rising of the water level and applies force in the first direction to one end of the lifting rod (30); or, the buoyancy component (20) comprises a floater (21), a water stopping cup (22) and a screw rod (23), wherein the floater (21) is movably connected in the water stopping cup (22), the screw rod (23) is fixedly connected with the floater (21), the floater (21) floats upwards along with rising of the water level, and the force in the first direction is applied to one end of the lifting rod (30) through the screw rod (23).
8. A piston feed valve as set forth in claim 1 or 5 wherein: the branch waterway (40) is formed in the water inlet body (10) and is independently connected with a water supply pipe, or the branch waterway is independent of the water inlet body (10) and is independently connected with the water supply pipe.
