Anonymous users2024-01-23The working principle of the flush toilet is not related to pressure and friction, but to buoyancy and pressure, and the principle of levers is used.
When there is no water in the toilet, the float goes down to the lowest point due to its own weight, and the other end of the float is connected to the toilet water inlet switch in the open position, and the water flow channel is open. When the water accumulates to a certain position, due to the buoyancy action, the float rises, and the connecting rod at the other end of the float closes the water inlet channel. Of course, the opening and closing positions of the water inlet switch should be adjusted to the range of the linkage movement when the float is lifted.

1.Calculate the pressure of the water on the outlet plug when the tank is full of water (F= is the area of the outlet plug);
2.By the balance of the torque, calculate the force required to pull the water discharge knob when discharging water;
3.Calculate the buoyancy force experienced by the float (F = gV row. For the measurement of row V, please refer to the "Student Achievement Display");
4.The pressure (or pressure) of the water at the inlet is calculated by the balance of the moment (Note: due to the complex structure of the inlet and the inlet plug, the force arm of the pressure of the water on the inlet plug can be approximately equal to the radius of the inlet pipe).
5.Calculate the velocity of the water flow at the mouth (Bernoulli's equation).
The "pumping" of the flush toilet refers to the S-shaped bend under the toilet, and when the water surface in the toilet exceeds the high point of the S-bend, the siphon phenomenon is formed, which can pump the water and dirt of the toilet together. Until only a small amount of water remains, the siphon destroys, leaving a small amount of water, forming a water seal. >>>More
A flush toilet consists of the following main parts: inlet pipe, outlet pipe, seepage pipe, plug (inlet and outlet), float, drain knob and lever. Be sure to understand the role of each of the above components in the work. >>>More
When discharging water, pull the drain knob, and the knob pulls up the water outlet plug through the lever. In this way, the water from the tank will be released. After the water is released, the outlet plug falls down, blocking the water outlet. >>>More
