【正文】 g against leakage, the floor is to avoid using a place often damp , makes the patient , the medical personnel slip down , an accident happened. Operation waits for the operating room , the delivery room to wash hands should adopt the constant temperature muddy water valve , the constant temperature to produce water, taking as an example infrared ray induced electromagic valve control mode for fine. Cure skill part control laboratory , laboratory of administrative or tehical office have the peculiar request , water chews the form should ascertain whose water according to every administrative or tehical office ing functional request chewing. 7)Many administrative or tehical office, especially downstream pipelines such as pickling bath , the pool disinfecting , develop pool in administrative or tehical office such as checking the room , the control laboratory , emitting section responds to of hospitals are adopt to be able to bear the rotten PVC2U draining off silent stock tube. 8) Pair of filth , waste water of all kinds must classify strictly according to the country in connection with the effluent standard , the field carrying out a pertinency with different treatment handicraft deals with and handles. 9) Uses a function to need since the modern hospital needs to be satisfied with not only , wants to think that the interior outside environment is beautiful too at the same time. The building needs especially door emergency call, cures skill sometimes because of medical treatment function , give the horizontal stroke draining away water , erect a tube arrange to lie scattered paratively, more bright dew is in interior, warm the pipeline exchanging special field up in addition sometimes , make the pipeline that the room inner clearly shows more than the correct or required number , both inelegant, and affect hygiene. This demands right away in the process of engineering design , the rational arrangement the structure form should fully utilize not being the same as is carried out, needs to make the various pipeline conceal arrangement to the full according to the function , pays attention to beautiful befitting one39。s to the same multilayer has been already sufficient , has been in a small town especially since but municipal administration pipe work water yield supplying water , water pressure fluctuation are bigger. Have several kinds the following types mainly for overe these shortings , multilayer water supply system design. 1) Direct water supply type is that pressure , direct water supply , sort making use of municipal administration pipe work directly apply to slightly high area of municipal administration pipe work pressure or higher range of water works vicinity pressure inner. The shorting it is water yield , water pressure to be able to not ensure that. This water supply scheme economy function is very good but, to less pipe work of scale , does not need any other equipment or measure. 2) Water box water supply types have led municipal administration pipe work water to roof water box , discrepancy in elevation , gravity depending on a water box and using the water appliance have supplied water , have overe water pressure water yield block of wood stability and then. Since but, secondary pollution, moreover, water box volume that the water box there exists in possibility is bigger,this way does not encourage therefore. 3) Water boxes , pipe works ally self with a type when the ordinary time water yield water pressure is sufficient , unnecessary water enters the roof water box when covering water supply , overpressure as with a directly from municipal administration, think that the water box supplies water to the consumer by gravi
