【正文】 development, the modern science and technology and the modern industry development, also has provided the condition for the highrise construction,20Century50Since the age, in the our country big city has constructed one batch of highrise constructions one after another. Specially80Since the age later our country will have implemented the reform and open policy, the economic development will change with each new day, the highrise construction in the big or mediasized cities and even small town city like mushroom growth rising straight from the ground, the development will be very quick. According to Shanghai2,002The year statistical count indicated the highrise construction has reached5,000Yu Dong. The highrise construction is saving with, the magnificent city and improves aspect the and so on people quality of life superiority has recognized as each person. The highrise construction fire fighting emergency is not easy to bee now the fire to save goal“Three is difficult”O(jiān)ne (“Three is difficult”Is refers to the highrise construction, the underground project, the petroleum chemical industry three kind of fires), but the highrise construction fire fire prevention gives the water is the fire fighting foundation, also is difficult to be difficult. The highrise construction although bases helps oneself, but falls behind helps oneself the system once to malfunction, or helps oneself the system although to be possible to work but cannot satisfy the use potency, the fire fighting also must depend upon the fire brigade the motion facility and equips saves goal. The housing achievement supplies the family housing use the construction, is important place which the humanity must not be possible from bottow to top to lack. In the correct processing housing design meets the fire question, relates directly to people39。 The office building is suitable is350～450KPa?！監(jiān)ur country the fire prevention the temporary high tension system is in the majority at present for the aqueous system in, the general highrise construction all is equipped with the top digit fire prevention water tank. Increases in not many situations in the top digit water tank dischargeable capacity, the life water storage and the fire prevention store water at the same time stores in a water tank, this both the economy and is advantageous for the management. The top digit water tank has the constant voltage function, causes the cold hot water system hydraulic pressure maintenance balance, facilitates takes a bath. The frequency conversion velocity modulation water pump cannot satisfy the fire prevention to store the water volume, has the small current capacity and the zero current capacity water supply question, at the same time the frequency conversion control stock price is high, uses few in the highrise construction. The barometric pressure pot is the barometric pressure pot adjustment volume is small for the water way main shorting, the similar existence cannot satisfy the question which the fire prevention stores water, the general achievement fire prevention for the aqueous system in regular pressure unit, uses in generally regarding the highrise construction life for the water time the minority floor hydraulic pressure insufficiency turbocharged. Because above many reasons, the overwhelming majority highrise construction uses the top d
