What is the control system of a flush toilet

The design requirements are that this is an automatic control, so a closed-loop control system is chosen.

The controlled object is the water tank of the flush toilet, the controlled quantity is the height of the water level of the flush toilet tank, and the control quantity is the water flow rate (inlet water) of the inlet pipe, and there is a linear relationship between the height of the water level of the water tank and the amount of water intake.

The main disturbance factor is the outflow of the tank. Schematic concept:

A float is used as a device for detecting the height of the water level. When the water level of the water tank is lower than a certain height of the water tank, there is a water level difference (the difference between the given water level height and the actual water level height), and this signal is transmitted to the water inlet valve through the float and the connecting rod mechanism, so that the water inlet valve is opened, so that the water tank is injected; When the water level of the tank reaches a certain height of the tank, the water level difference is zero and the inlet valve is closed. Design of automatic control system for flush toilet tanks.

Utilize the water discharge knob and the water plug to control the water discharge and water storage, when using, rotate the water discharge knob, use the metal rope or nylon rope connecting the water plug to pull up the water plug, the water plug pulls out the water outlet pipe port upward, the water outlet pipe puts the water into the urinal and uses the gravity of the water and the kinetic energy converted by the potential energy to flush the excrement dirt into the sewer pipe, and at the same time, when the water level drops to a certain water level, the water plug is re-pressed into the port of the outlet pipe due to the negative pressure generated by the gravity of the water, and the water outlet is blocked. At this time, the water is no longer released and a new stage of water storage begins; When the water level drops, while flushing the urinal, the float together with the lever is driven by the gravity of the float due to the drop in the water level, and the lever is opened to start synchronous water replenishment; The water replenishment phase uses the buoyancy and lever of the float to control the water replenishment of the tank, and the float is lowered to the lowest position just when the water plug is in place.

The water tank is pressed into and out of the pipe mouth by negative pressure, and the water tank begins to store water; The water inlet pipe is connected to the water pipe, which is responsible for the input of the water source, and when the water supply reaches a certain height, the buoyancy of the water will lift the float and close the linkage lever.

Toilet, the bathroom necessities of daily life, this is a must for every family, but if we do not understand the structure and principle of the toilet at all, then when the toilet has a small problem, we are stumped, in fact, the working principle of the toilet is very simple, but we have not really understood the toilet yet, if we understand it will no longer feel that the toilet is just dirty, smelly impression.

How the flush toilet works:

1. When you press the button, you pull the chain inside the toilet, so you can open the flush valve.

2. Then you will find that there is a large amount of water in the tank to flush into the toilet, so as to flush it clean, and then the flush valve will also return to its original position.

3. The impulse of the water will activate the siphon in the urinal, and the siphon will suck the dirt in the urinal into the drain.

4. At the same time, the water level in the tank will drop, and the floating block will also drop. The lowered float opens the water valve.

5. The water flows through the water valve to fill the water tank and urinal. When the tank is filled with water, the float will float up, and when the float reaches a certain height, the water supply valve will close.

6. If the toilet is faulty and the water valve cannot be closed, the overflow pipe can prevent the water in the tank from overflowing.

A kind of multi-tank water level automatic control system, used to control the water level of many water tanks with different heights and different water consumption in real time, it can ensure that many water tanks are neither short of water nor water with the fastest speed and the least number of start-ups. Its controller is mainly composed of a plurality of identical parts and manual operation parts, pump action control parts, and each part of these plurality of identical parts is composed of sampling part, logic processing part, display part, detection part and pushing action part. A multi-tank water level automatic control system is made up of controller, water pump, at least one water tank and electrodes located in each water tank and solenoid valves located at water pumps to each water tank pipeline, and electrodes are respectively located at three endpoints of water tank bottom, middle and upper part, and are characterized in that:

The controller is made up of a manual operation part, a water pump action control part and another plurality of identical parts, and each part of this plurality of identical parts is made up of a sampling part, a logic processing part, a display part, a detection part and a pushing action part.
