What is a centrifugal drainage tee? What s the name of this drain fitting, that tee?

The key is to see whether the supervisor is difficult for you or if you really don't understand. If it is difficult for you, then it is necessary for you to invite him to eat and soak his feet. If you really don't understand, then you explain it to him:

According to the Code for the Design of Water Supply and Drainage in Buildings GB 50015-2003-4 in 4 3 .9, the connection of indoor pipes shall comply with the following provisions:

1. The drainage pipe of sanitary appliances is vertically connected with the drainage horizontal pipe, and 90o oblique tee should be used.

2. The horizontal pipe of the drainage pipe is connected with the riser, and it is advisable to use 45o oblique tee or 45o oblique tee and shunshui tee or shunshui tee.

Meaning:

1. It means that it is very strict and must be done: the positive word is "must", and the negative word is "strictly prohibited".

2. It means that it is strict, and it should be done under normal circumstances: the positive word should be "shall", and the negative word should be "should not" or "shall not". 3. Indicates that a slight choice is allowed, and it is the first to do so when conditions permit:

The positive word is "appropriate" or "may", and the negative word is "unsuitable". Indicates that there is a choice, and that this can be done under certain conditions, the word "may" is used. Therefore, it is certainly no problem for the riser and horizontal pipe to use a smooth tee, and the horizontal pipe and the board executive should try to use an oblique tee, but it is not necessary.

You're talking about special pipe fittings for inner spiral pipes, right? This is a specialized fitting.

You can replace the new tee and saw off the old tee

Step 1: Leave a centimeter from the middle of the tee to see the defeat file

The second step is to leave one centimeter at both ends of the tee and saw

The third step is to slowly remove the tee shell stuck to the PVC pipe with a flat screwdriver and remove the smooth

The fourth step is to apply glue to the dry imitation of the tube and the new tee

The fifth step is to break open any tube with a little force and force the tee on.

Precautions: If you can't push it, you can saw off a little more pipe, or saw the nozzle with a slight bevel; Its delicate glue should be evenly coated; Finally, after it is finished, the tee and the pipe interface are coated with glue.

The cast iron drainage pipe Ty tee and Y tee mean pictographic tee, both of which are one of the oblique tees with three mouths.

Cast iron drainage pipe TY tee and Y tee are basically the same, with only one difference: the branch pipe of TY tee turns 90°, and when the branch pipe of TY tee no longer turns to 90°, it is Y tee, like the word "Bu" in Chinese.

Cast iron drainage pipe ty tee, Y tee is a pictographic tee, are one of the oblique tees, the picture below is a ty-shaped tee, when the branch pipe of the TY tee no longer turns to 90°, it is a y open tee, like the word "Bu" in Chinese.

This is T tee, Ty tee, Y tee, oblique Y tee.

It refers to the right-angle tee, the two ends are 400, the small head is 200, and the Y is an oblique tee. T is the code letter of the lead in the tee hole, 400-200-400 said that the director of the Ming Ming is 400, and the small mouth of the variable diameter is 200 400 and the potato is 200 tee.

It is a kind of sewer pipe fitting.

A riser is a pipe that is vertical. 3. General pipe fittings at the main pipeline branch.

In the sewer riser of the building, there is a problem when the sewage enters the riser from the side through the tee: the air in the lower pipe needs to be discharged when the sewage goes down, otherwise it will be compressed and cause the pressure to rise, either resist the sewage above and make it impossible to go down, or break the water seal of the drainage outlet on other floors and enter the room. There are three general ways to solve this problem:

The first is to increase the diameter of the riser, which is not applicable at the high-rise; The second is the use of double risers, when one pipeline sewage downstream, the gas is discharged from the other pipeline, which is more complicated; Then there is the use of a special single riser swirl tee.

The so-called special single riser swirl tee is to rotate the sewage flow through the structure of the tee, and under the action of centrifugal force, the sewage rotates downward against the riser pipe wall, and the space in the middle can make the gas discharged. This solves the problem of both double risers and ordinary single risers. Special single riser swirl tees are available in a variety of structural forms.

You can go to the Internet to search, there are manufacturers of this kind of pipe fittings, it mainly plays the role of noise reduction and space saving, the past high-rise drainage H-type double riser drainage system to a pipe with a special single riser connection drainage mode. The water flows through a special single riser cyclone, and under the action of the guide vanes, the water flow rotates and falls along the inner wall of the pipe, forming an air column in the middle of the pipe. Now it's being used more and more in projects.

Liaoning Jinhe's HPS system is recommended, with the best displacement.

Drainage, energy saving and noise reduction, at present, the country is vigorously promoting, the first-line brands are: Qingdao Jishui, Kunming Qunzhiying, Jining Guanya, Chongqing Yangtze River, Hebei Xinghua.

**Find on, there are quite a lot, search, single riser tee can be,

There is a DT type special single riser swirl tee which is very good, we have used it once, and it is very good in terms of workmanship or **.

Three-way wells and four-way wells are both a kind of inspection wells, but the direction of the inlet and outlet water of the well.

Generally speaking, the three and four links are the connection of the supervisor, and have little impact on the branch pipe.

Like the rainwater of the road part, the normal straight well, for example, the pipe diameter is DN400mm, if there is a pipeline access for rainwater collection, the pipe diameter is generally DN225mm, which is a branch pipe, then this kind of well is usually not called a tee.

The third and fourth crosses are generally used for pipeline intersection and diversion or collection, of course, some are well locations set up according to the actual situation.

The number of inspection wells mainly refers to the number of special water outlets at the bottom of the DAO well chamber.

The main pipe has 1 direction of inflow and 1 direction of outflow, and the other inlets are branch pipes flowing in. The diameter of the main pipe is larger, and the diameter of the branch is smaller.

It has nothing to do with the rainwater outlet reserved for the wellbore (or the upper part of the well chamber) to collect road rainwater.

Of course, it has something to do with the main and branch pipes, which can be understood literally.
