The kitchen is the second most important occasion for our renovations. The kitchen has many pipes and sewers. At the beginning of the installation, the sewers should think about problems that may arise in the future. Sometimes there will be water in the kitchen sewers. I don't know if you have experienced it. How to solve this situation? Then let Xiaobian take everyone to look at the relevant contents of the kitchen sewer anti-water related content.
Poor hydraulic conditions The residential drainage is generally gravity gravity drainage. The sewage is discharged into the drainage riser by the sanitary ware of the house, and then discharged into the drainage transverse pipe. Finally discharged into the outdoor drainage inspection well. Generally, the drainage speed of the drainage riser is greater than that of the drainage transverse pipe. When the sewage is discharged to the bottom of the drainage riser and transferred to the drainage transverse pipe, instantaneous congestion will occur, and the sewage will overflow from the sanitary appliances of the bottom house. This is commonly said. The sewer is anti-water.
Solution: First of all, all the unfavorable factors should be taken into consideration when designing the house. The drainage pipe should be arranged to meet the optimal hydraulic conditions. Therefore, special attention should be paid to: The connection between the drainage riser and the drainage transverse pipe should be carried out by using two 45 or elbows with a bending radius of not less than 4 pipe diameters. The drainage horizontal pipe should be connected as straight as possible and with less turning. The pipe diameter and slope of the drainage horizontal pipe are appropriately enlarged.
Pipe problems In the past, the drainage pipes of houses were generally sand mold cast iron pipes. The inner wall was rough and easy to hang dirt. The anti-corrosion was not easy to rust, resulting in poor drainage. The plastic drain pipe and the mechanism centrifugal cast iron pipe have smooth inner walls, and the dirt is not easy to accumulate and cause blockage.
Pipeline problem solution: For the completed house, if the backwater problem of the bottom house is very serious due to the pipe problem, the original drain pipe needs to be rebuilt. At this time, the plastic drain pipe or the mechanism centrifugal cast iron pipe should be used.
Large settlement of houses The slope of the drainage trunks generally meets the standard slope during construction. The flow rate of sewage in the pipeline can reach the self-cleaning flow rate. It is normal for the house to be settled due to its own weight and unreliable foundation. However, it was not given great attention during the design and construction, and corresponding measures were taken. As a result, the settlement of the house was large, and the drainage pipe was pressed, resulting in drainage. The slope of the household pipe is reduced, even when the slope is reversed. In severe cases, the drainage pipe will be crushed, resulting in poor drainage.
Large settlement of housing settlement:
(1) When the drainage pipe penetrates the foundation, the settlement above the pipe top should be left, generally not less than 150mm.
(2) Increase the slope of the drainage outlet and leave a room for manoeuvre.
However, it should be noted that if the slope of the drainage pipe is too large, the pipeline will be oversized and affect the service life of the pipeline. Generally, the slope of the drainage pipeline should not exceed 0??15. (3) After the residential cap is closed, the drainage and discharge pipe will be constructed. At this time, the initial settlement of the building is completed, and the settlement space is limited later, which can reduce the damage of the house settlement to the pipe.
How about, I read the relevant introduction to the anti-water in the kitchen sewer, and I also learned a lot about the anti-water content of the kitchen sewer. I hope that you can learn more about home improvement knowledge through this article, and you will be able to create a more perfect home environment. Thank you for reading this article and your support and love for Xiaobian. If you want to get more information about home improvement, please continue to pay attention to the decoration home network.
BS Couplings, that is BS 336 instantaneous couplings are British normed quick-disconnect couplings that can be used in fire brigades and for general industrial use.
The lock mechanism goes with the coupler bodies. BS couplings are commonly required with hose shank, male and female threads, blind caps and plugs.
