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 7 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 on the down part is that several special field arrangement props up the public space being in charge of , down part is to arrange to give draining off , driving force , strong , weak electricity every system to do a tube again. Such is arranged than form arrangement is other paratively economical , pragmatic. 10) Exchangers forms choice. In the system the tradition hospital hot water is supplied, people adopt volume mainly dyadic exchanger. Have been to think that what be provided steam amounts and hot water supplies the adjustment amounts dispatching value between maximum value mainly , have diminished a steam boiler designing amounts , have decreased by boiler room Zhan field area , have saved one time investment. People demands but more highly, and more highly, especially the example discovering army group bacterium pathopoiesia in life hot water to water quality now , the altitude arousing people takes seriously. Be a bacterium mainly because of in the water 55 ~C is the easiest to breed an army group in 30 ~C ~, WHO (WHO) is remended by for this purpose: Hot water responds to in 60 ~C use And cycle at least above 50 ~C. Come if some users, need to fall to 40 ~C or 50 ~C or so with the faucet water temperature, to e true being able to use a thermoregulation to blend a valve at this time. The growth being a temperature Bu Li Yu pneumonia diplococcus swear to store water, is a regulating valve39。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 p
