How does a flush toilet work, what is the working principle of a flush toilet

The toilet works as follows: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 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.

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.

At this time, the float is also at the bottom of the tank due to the drop of the water surface. The fall of the float drives the lever to pull up the water inlet plug and let the water enter the tank. As the water rises, the float will gradually increase due to buoyancy until the inlet plug is pressed down by a lever and the inlet is blocked.

This fills the tank with water again. Think about it, what is the purpose of the adjustable knob?

When the inlet pipe leaks due to a malfunction (e.g., the inlet plug fails to block the inlet or the inlet pipe breaks), the water level in the tank will continue to rise and eventually overflow the tank. And the setting of the seepage pipe solves this problem.

When the water level rises to the seepage nozzle, the water flows into the toilet bowl from the seepage pipe and does not allow the water to overflow the tank. When the inlet pipe is working normally, the water surface in the tank will not reach the seepage nozzle, so there is no need to worry about the water flowing away.

As shown in the experiment, when the coarse straw is placed over the thin straw and inserted vertically into the water and raised slightly, the coarse and thin straws form a special siphon, and the water continues to flow down the thin pipe. Flush toilets also make use of the principle of siphons.

Flush toilet principle: under the flush toilet, there is an invisible invisible, inverted U-shaped bend, when the sewage is discharged, when the water surface in the toilet exceeds the high point of the S bend, the siphon phenomenon is formed, which can pump away 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.

When you need to flush the toilet, a large amount of clean water in the water storage tank will pour into the toilet from the water inlet pipe at a very fast speed, the whole process only takes about three seconds, the water level in the toilet will rise rapidly, and the water level in the toilet elbow will also rise synchronously, when the water level in the elbow rises to the top of the pipe, with its own gravity, the water will squeeze out the air in the elbow, flow down the pipe, and fill the pipe, and at this time there is a siphon phenomenon, the water continues to cross from the highest point, flow out of the elbow, once the water in the pipe flows rapidly, You can suck the feces and debris in the toilet bowl together and discharge them, so as to complete its cleaning task.

The siphon phenomenon can be generated, mainly because the water surface of the nozzle bears different atmospheric pressure and water pressure, and the water will flow from the side with high pressure to the side with low pressure, and the pressure difference of the water column is used, so that the water column flows out of the pipe, so that the flushing toilet can work repeatedly. The feces flushed out of the flush toilet will flow into the septic tank, where it will be used as fertilizer after a series of anaerobic fermentation, effectively reducing environmental pollution.

Flush toilet cleaning method

1. Vinegar descaling method: pour the mixed liquid of vinegar and water into the toilet, and after soaking for half a day, the scale will be brushed off.

2. Sandpaper descaling method: use the finest sandpaper to rub the dirt of the toilet bowl, which can remove the dirt that cannot be removed by the cleaning banquet agent.

3. Baking soda descaling: Sprinkle baking soda in the toilet, then brew with hot boiling water for half an hour, and the dirt can be brushed off.

4. Bleaching powder solution descaling method: wipe it with bleaching powder solution first, and then rinse it with water after a while.

5. Homemade small brush to scrub the toilet: the flush toilet produces yellow dirt, which is difficult to clean with a brush, you can tie the waste nylon socks to one end of the stick, dip it in foaming detergent to scrub, clean it for 1 month, and keep the toilet white.

6. Detergent descaling: first put an appropriate amount of water in the toilet, clean it with a toilet brush, then pour in 5-10 ml of detergent or hydrochloric acid solution, apply it evenly with a brush and then scrub it. If the dirt is heavy, you can pour a little more detergent to soak and brush until it is clean.

Hydrochloric acid has a strong corrosiveness, if you use hydrochloric acid to clean, pay attention to safety, do not splash on the ** Tan Xiang Kong, and the acidity of hydrochloric acid is relatively strong, and it will cause damage to the material of the toilet bowl if you do not pay attention to it during use, so you must pay attention to dilution when using.
