What is the principle of toilet sealing? What does a toilet seal mean?

A water seal is a water column with a certain height in the device to prevent gas from escaping into the room in the drain pipe system. In building drainage pipes, water seals refer to the water column of a certain height located under the drainage outlet of sanitary appliances to resist the change of air pressure difference in the drainage pipe and prevent gas from escaping into the room in the drainage pipe system. ”

Toilet water seal is actually a siphon phenomenon, using the principles of physics, using pressure to make water flow from a low place to a high place. Then use the pressure to flow out.

Toilet water seal refers to the water column with a certain height in the toilet bowl to prevent gas from escaping into the room in the drain pipe system.

Toilet water seal refers to the flow of water in the toilet bowl at a certain height to prevent the vapor in the drainage system software from escaping into the room. In the sewage pipeline of engineering construction, the water seal refers to the water seal built under the outlet of environmental sanitation equipment, which is used to resist the change of standard air pressure difference in the drainage pipeline, and to avoid the water flow of a certain height in the sewage pipeline system software, which is generally completed by a water trap.

Water seal is a division method that uses water to isolate two parts of gas to be isolated. The most common type of this is a household flush toilet. When there is no water seal in the sanitary appliances, a water seal device should be set at the connection between the indoor drainage ditch and the outdoor drainage pipe, and the water seal depth shall not be less than 50mm.

Toilet seal height adjustment method

1. The water seal height of some toilets can be adjusted, but most of the toilet water is not adjustable. The height of the toilet seal is related to the flush volume, and we can adjust the flush volume appropriately. We open the toilet water lid, find the small pillar next to the float, rotate the column to adjust the position of the float, the position of the float represents the water level, and the high water level indicates the large amount of water.

2. The toilet water seal can play a sealing role and can isolate the harmful gases of the sewer from entering the room. The toilet bowl is sealed by means of a trap, which is usually located under the drain. If the water seal is too high, it will cause solid impurities to be easily deposited at the bottom of the water trap, causing the toilet to be blocked; If the water seal height is too low, its odor insulation effect is not good.

According to the relevant regulations of our country, the height of the toilet water seal must be higher than 50mm, and the area of the water seal should not be less than 100*85mm.

3. The smell in the bathroom is not necessarily caused by the toilet water seal being too low, it may be caused by a problem with the connection between the toilet and the sewer; There is a problem with the sealing ring at the bottom of the toilet, etc.; Or it may be caused by the floor drain is not odorproof and the sewer pipe does not have an S bend. After determining the cause of the odor, we should repair and deal with it in time.

4. If you want to remove the odor in the bathroom, we can place used honeycomb coal, lemon, vinegar, cool oil, etc. in the bathroom; Or we can apply a few drops of toilet water to the toilet light and wait until the toilet water has evaporated before turning on the light; Or we dry the waste tea leaves and burn them in the bathroom, etc.

The principle is to make the pressure of the gas through a certain water level, the height of the water in the rainwater seal to reach the balance of pressure, remove the condensate in the gas or seal the gas collector; Toilet water seal is to accumulate a certain amount of water at the drain of the toilet, and then assemble a drain pipe to pass the odor through the drain of the toilet bowl and reflect the smell in the room.

At the drain of the toilet, when the amount of water is stored to a certain amount, it will not be stored, and the density of water is a little less than that of other solutions; It is to accumulate a certain amount of water, and then prevent the odor in the drain system from passing through the drain of the toilet bowl and returning the smell to the room.

Toilet water seal is mainly a hydrodynamic phenomenon, using the liquid angle and pressure difference, controlled by a button, to achieve flushing.

This is related to siphoning, which is mainly done for better sealing and avoiding odors.
