What kind of concept is rainbow leakage in drainage practice?

Maiwei Animation Co., Ltd. focuses on the three-dimensional animation design of the principle of high-quality siphon speed drainage system. 3D animation showing the siphon velocity drainage system.

To analyze the pressure at the highest point of the tube, you will find that the pressure on both sides is not the same, and the pressure is equal to the product of height and density].

In the past, the thatched houses used by people were dirty, smelly and unhygienic. With people's living standards getting higher and higher, every household now uses a clean and tidy toilet.

So what is the difference between the toilet in the bathroom and the flush type?

First of all, the flush toilet is relatively loud when flushing, and at the same time, the flushing force is also very strong, and it can be flushed cleanly.

The second is the siphon toilet that flushes relatively quietly, but has a strong odor prevention function. In addition, due to the complexity of the structure of its drainage pipe, it is a waste of water.

That's some of my personal opinions.

Hope it helps, thanks.

The direct flushing toilet is stronger than the siphon toilet, and it is easier to flush away the dirty things that are larger, and it generally does not cause the toilet to be blocked, but it also has disadvantages, that is, the flushing sound is relatively loud, and the odor prevention is not as good as that of the siphon toilet.

The advantage of the siphon toilet is that it is low noise, and it is easy to flush away the dirt that adheres to the surface of the toilet, and the odor prevention effect is good, but it also has the disadvantage, that is, wastewater, and when the water is small, it will cause blockage.

These two types of toilets have their own advantages and disadvantages, and you can choose according to your own needs.

The direct flushing type flushing speed is fast, the impulse is large, the strong sewage discharge, the water pipeline is straight, the water is water-saving, the shortcomings are noisy, the siphon noise is small, the sewage discharge capacity is strong, the washing surface is large, the vast majority of people use the siphon siphon toilet There is a complete pipe in the toilet, the shape is a side-inverted "S", the slope of the pool wall is slow, and the noise problem has been improved; It has the characteristics of strong sewage discharge capacity and large clean surface, so the vast majority of toilets, especially the conjoined ones, are siphon type. The advantage is that the flushing noise is low, which is called silence. It is easy to flush off dirt that adheres to the surface of the toilet.

The flush toilet uses a large thrust formed by the compressed air, with fast flushing speed, large punch, strong sewage discharge, fast speed, less water use, and no leakage. Because the flush type uses the instantaneous and powerful kinetic energy of the water flow, the sound of hitting the pipe wall is relatively loud. The rear drainage is mostly a direct flush type.

The flush toilet drain pipe has a large diameter, which is easy to flush down larger dirt.

Siphon and flush toilets have their own advantages and disadvantages, and the comparison is as follows:1Flush effect:

Siphon: the neck of the tube is slender, the water surface is very high when flushing, and the filth goes down with the water, and the water seal is high, which is not easy to reject. Straight Rush:

The pipeline is simple, the path is short, the neck is thick, and the dirt can be easily washed away by the gravitational acceleration of water, which is not easy to cause blockage, but it is easy to produce peculiar smell. 2.Flushing noise:

Siphon: It is a suction type sewage method, the impact sound of the water flow is very small, and the flushing sound is particularly small, which is called a silent toilet. Straight Rush:

Use the instantaneous powerful energy of the water flow to wash away the filth, the sound of the water hitting the pipe wall and the water on the water tank is relatively loud, and the sound of flushing is relatively loud. 3.Water Saving Effect:

Siphon: The design structure determines that a little more water needs to be stored in the return bay to isolate odors, and the water consumption is relatively higher than that of direct flushing. Straight Rush:

The gravitational acceleration of water is used to flush out the filth, and the amount of water used is less at a time. 4.Market Price:

Flush toilets** are relatively inexpensive.

1. Siphon type.

Siphoning refers to the rapid formation of a liquid height difference under atmospheric pressure, so that the liquid flows from the high water level with high pressure to the low water level with low pressure, and fills the sewage pipe to produce a siphon phenomenon until the liquid is all discharged into the air.

There are two kinds of siphon siphons: vortex siphon and jet siphon.

The whirlpool siphon toilet flush port is located on the side of the bottom of the toilet, and the water flow forms a vortex along the pool wall when flushing, which will increase the flushing force of the water flow on the pool wall, and also increase the suction power of the siphon effect, which is more conducive to the discharge of toilet viscera.

Jet siphon toilet adds a jet secondary channel at the bottom of the toilet, aimed at the center of the sewage outlet, when flushing, part of the water flows out from the water hole around the toilet circle, and part of it is sprayed out by the jet port, this kind of toilet is on the basis of siphon with the help of a larger water flow impulse, the dirt is quickly flushed away.

Advantages: It is very quiet and good-looking, it seems to have a high feeling, and many big brands mainly promote siphons.

Cons: 1The diameter of the pipe is about 56 cm, which is converted into a water area, which is about three times worse than that of the direct flushing type, and it is very easy to block when flushing.

2.Because the smaller the pipe diameter, the more obvious the effect of the siphon and the greater the pumping force. But inevitably, the demand for water is greater.

Second, the straight flush type.

The flush flush line is simple, the path is short, and the pipe diameter is thick, and the gravitational acceleration of the water can be used to flush away the dirt. There is no backflow bend in the design of this toilet, and it is not easy to cause blockage in the flushing process compared with the siphon type, and it is easier to flush out relatively large dirt;

The flush toilet also depends on the plumbing design of the floor, and if the developer does not reserve a water trap, it is not easy to prevent odors if the toilet is not ready.

Advantages: no clogging, water saving. Can do a real 3-6 liter flush. In fact, cheap is also an advantage, the same brand, straight rush is generally cheaper than siphon.

Disadvantages: noisy, unsightly.

In conclusion, flush toilets are noisy when flushing, while siphon toilets are less noisy. The principle of flushing is different, so the structure of the toilet is different. In contrast, the siphon toilet has more advantages, such as a larger flushing force, and the relative water consumption (some toilet designs) is smaller.

Moreover, the siphon type appeared after the flush type, so the siphon toilet on the market is gradually occupying the market and has the tendency to replace the flush toilet.

In the siphon toilet, there are several subdivisions according to the structural principle. But in general, it's all the rainbow principle. From the point of view, the toilet of the same brand, the siphon type is more expensive.

Siphon is the main feature of the toilet is that the nozzle is relatively small, but the confusion is relatively large, the feces are not easy to block in the pipe, but easy to be easy in the nozzle, which is a particularly fatal point, but the noise of the siphon toilet flushing is not large, but the requirements for pumping water are relatively high, the whole pipe structure is basically S-shaped, resulting in excrement is very easy to block, which is why the four toilets at home are often easy to block. The flush toilet is better than its entire pipe, which does not need to be bent and winded, and flushes straight down in an L-shape, using the gravitational speed of the water to flush the excrement clean, which has the advantage of no anti-water pipe. Compared with the siphon, the toilet is not easy to cause blockage in the process of flushing, but the noise is relatively loud, and the flushing phase is not very good-looking.

Siphon roof rainwater drainage working principle.

The siphon roof rainwater drainage system and the gravity roof rainwater drainage system are composed of rainwater bucket, rainwater suspension pipe, rainwater riser and rainwater buried pipe, but because the working principle of the system is completely different, it works under two different hydraulic conditions, so the functional requirements of each component in the system are different, and the system also has its corresponding set of calculation methods. The biggest improvement and technological advancement of the siphon roof stormwater drainage system is the development of a rainwater hopper with good rectification function. The rainwater bucket is in a state of submerged discharge and drainage when its rated design flow rate, and it is not breathable; Large design displacement; The water depth in front of the bucket when the rainwater bucket is flooded and discharged is small.

The roof rainwater drainage system using siphon rainwater bucket is equivalent to discharging water from a pool with a stable water surface on the roof during the rainfall process, and is discharged from the discharge pipe through the drainage pipe system in the roof, and the pipe is full of pressure flow state, and the drainage process of the surface rainwater is a siphon drainage process. Therefore, the roof rainwater drainage system with siphon drainage capacity is called the siphon roof rainwater drainage system. The pipe of the siphon roof drainage system is negative pressure in the design rainfall intensity, the selection of pipes should consider the ability to withstand negative pressure, the water level in front of the bucket of rainwater bucket submersion and discharge is reduced to a certain value, the rainwater bucket begins to have air infiltration, the vacuum in the drainage pipe is destroyed, and the drainage system will turn from the working condition of siphon pressure flow to gravity flow.

The principle of the siphon roof rainwater system is to rely on the design of a special rainwater bucket to implement air-water separation, so that the rainwater riser is in a full flow state, and when the water in the riser reaches a certain capacity, the siphon effect is generated. During the rainfall, the entire system is able to remove rainwater from the roof surprisingly quickly due to the continuous siphoning.

1.Features of siphon roof drainage system.

In the early stage of rainfall, when the height of the roof rainwater does not exceed the height of the rainwater hopper, the working condition of the whole drainage system is the same as that of the gravity drainage system.

With the continuation of rainfall, when the height of the roof rainwater exceeds the height of the rainwater bucket, due to the use of the scientific design of the anti-whirlpool rainwater bucket, by controlling the rainwater flow into the rainwater bucket and adjusting the flow regime to reduce the whirlpool, thereby greatly reducing the amount of air entrained when the rainwater enters the drainage system, so that the drainage pipe in the system is in a full flow state, using the height of the roof of the building and the potential energy of the rainwater, when the rainwater continuous flow through the rainwater suspension pipe into the rainwater riser falls, the siphon effect is formed. and the maximum negative pressure in the pipe there. Roof rainwater is discharged to the outside at a high flow rate under the suction action of negative pressure in the pipe.

2.The difference between siphon and gravity and surface stormwater drainage systems.

The drainage pipes of the siphon roof rainwater drainage system are designed according to the full flow and pressure state, so the rainwater suspension pipe in the siphon drainage system can be laid without slope. At the same time, when the siphon effect is generated, the water flow velocity in the pipeline is very high, so the system has a good self-cleaning effect. The gravity drainage design calculation is not calculated according to the full flow, and the laying slope of the rainwater suspension pipe shall not be less than.

The discharge volume of the drainage pipe in the siphon drainage system is much greater than the discharge volume of the drainage pipe of the same diameter in the gravity drainage system, that is, the drainage pipe diameter of the siphon drainage system is smaller than the drainage pipe diameter of the gravity drainage system.

The siphon drainage system is essentially a multi-bucket pressure flow rainwater drainage system. Therefore, the buried pipe is significantly reduced compared with the gravity drainage system.

When using the siphon drainage system, it is necessary to be able to control the water depth in front of the bucket, and secondly, to choose the appropriate drainage pipe diameter, it is important to have a good grasp of the actual local situation during the rainstorm period. Chuangchi Siphon Drainage is very professional in technical services, and it is very thoughtful from the beginning of consulting and design, and will also provide customers with professional training, which will tell you the precautions and how to check.

Gravity flow stormwater systems require the flow of the control system to be within the designed gravity flow range. Otherwise, the excess flow of rainwater into the system, the flow regime will exceed gravity without pressure flow, and the violent pressure fluctuation will cause damage to the system, such as damage to the riser, water in the indoor inspection well and other safety accidents.

The horizontal pipe of the siphon system can be installed horizontally, while the horizontal pipe of the gravity flow system must have a slope of not less than that, which will make the end of the horizontal pipe lower, thereby affecting the use of space or affecting the treatment of the building structure. Due to the small number of risers of the siphon system, they can be laid in stairwells, columns, etc., without taking up more space, and the horizontal pipes can also be laid in non-sensitive public corridors. In short, to give a favorable condition for the design of the building.

With the continuation of rainfall, when the height of the roof rainwater exceeds the height of the rainwater bucket, due to the use of the scientific design of the anti-whirlpool rainwater bucket, by controlling the rainwater flow into the rainwater bucket and adjusting the flow regime to reduce the whirlpool, thereby greatly reducing the amount of air entrained when the rainwater enters the drainage system, so that the drainage pipe in the system is in a full flow state, using the height of the roof of the building and the potential energy of the rainwater, when the rainwater continuous flow through the rainwater suspension pipe into the rainwater riser falls, the siphon effect is formed. and the maximum negative pressure in the pipe there.

The overflow is located at a height of about 300mm on the roof, and when the rainwater accumulates to 300 mm high in the roof area, it is discharged from the overflow. Below 300 still need to be drained through a downspout.

Constant pressure overflow: In the fixed pump throttle adjustment system, the fixed pump provides a constant flow rate. When the system pressure increases, the flow demand decreases.

At this time, the relief valve is opened, so that the excess flow overflows back into the oil tank, and the inlet pressure of the relief valve, that is, the pressure at the outlet of the pump is constant (the valve port is often opened with pressure fluctuations).

Common types of overflow pipes are as follows:

1. When filling a large container with liquid, in order to avoid overflowing liquid or too much filling of a closed container, open the overflow port at the position where the container is allowed to fill the maximum amount of liquid, and connect it to the mother liquor with a pipe, which is called an overflow pipe. It is more common in chemical equipment.

2. In daily life, the small hole in the upper part of the sink is the overflow port.

3. The water pipe above the solar water storage tank is the overflow pipe.

4. There is a pipe on the side of the outer barrel of the washing machine from top to bottom, that is, the overflow pipe, open an overflow outlet at the maximum capacity position of the washing machine and connect the overflow pipe. When the water level in the bucket is higher than the maximum water level, it overflows through the overflow pipe to prevent electric shock from flooding.
