What are the design features of the drainage system in the laboratory?

The installation of laboratory design equipment has its technological characteristics, that is, there are many and loose water points, most of which use little water, and some introduction pipes are introduced into the room from the middle of the building, which makes the application of water pressure more balanced. There are many kinds of pipelines in laboratory design, which have special requirements for technology and construction; Some laboratories have ditches in the internal and bottom corridors; In this case, the water inlet pipe also enters the room from one end or both ends of the building.

The water supply and drainage supervisor and gas pipeline in the laboratory should be laid in the skill interlayer. In the laboratory design protection area, less pipelines should be laid, and pipelines unrelated to this area should not be crossed. Introduce the third and fourth biological laboratories to design pipelines in the protected areas. It is suggested that stainless steel pipes, copper pipes or non-toxic plastic pipes should be used for indoor water supply, and the pipeline connection is reliable. The water supply pipeline in the biological safety laboratory design protection area should be equipped with backflow prevention valves or other useful devices to prevent backflow pollution, which should be installed in the auxiliary operation area. The first and second biological laboratories should be equipped with hand washing equipment and should be located near the exit of the laboratory. The hand washing equipment designed by the third and fourth biological laboratories should be set at the exit of the main laboratory, and the water supply of the hand washing equipment should be non-manual switch. The design of large-scale animal biology laboratories and animal laboratories that need to clean cages should be equipped with necessary cleaning equipment.
