The principle of toilet cup type inlet valve

The buoyancy is used to block the small hole through the lever, and the black water-stopping rubber pad has the same external water pressure, but the action area of the black rubber pad (harder place) is larger than that of the catheter outlet, so the water outlet hole is blocked and the water stop is realized.

The working principle of the toilet inlet valve is to use the buoyancy of the water, the principle of lever, when the water is discharged, the float weight opens the valve, the water is in, when the water is discharged, the water seal falls completely, and the float is raised to close the valve upward after the water is inlet to control the water inlet of the water tank.

The working principle of the toilet inlet valve is to use the buoyancy of the water, the principle of lever, when the water is discharged, the float weight opens the valve, the water is in, when the water is discharged, the water seal falls completely, and the float is raised to close the valve upward after the water is inlet to control the water inlet of the water tank.

When there is no water in the water tank, the float lowers and opens the valve to start replenishing water, and when the water reaches the limit height of the float, the valve is closed.

There is a float in the toilet, as the water level in the toilet rises, the buoyancy generated by the float is getting bigger and bigger, when the water level rises to a predetermined value, the buoyancy generated by the float will be transmitted to the switch through a seesaw structure, the switch is closed and then the water inlet valve will not enter the water, when the water is released, the button or wrench pulls the plug of the water discharge, and the plug is automatically pulled out. After the water is discharged, the plug automatically returns to its position under the action of the spring and enters the next round of water filling cycle. >>>More
