Research On The Application Of Fire Water Supply System In High—rise Public Buildings

Fire water supply system in high-rise public buildings fire system an important part,because of the high-rise public buildings fire safety depends mainly on fire water system to protect,once there is a fire,fire water system will be able to immediately on dangerous for processing,in order to ensure the safety of personnel and property.Thus,we need to in-depth study of the high-rise public buildings fire water supply system,to optimize the design of related technology,the defects of the existing.This paper introduced the development status of the present stage domestic and foreign high-level public buildings fire water system and elaborates the advantages and disadvantages of each system,joint specifications and engineering experience,and we from the following several aspects explores the:the effects of the distribution of water spraying device in the system of the whole system,to assess the stability of the whole system and the subsystem optimization design.This paper introduces the theory of reliability performance indexes of the fire water system of were analyzed and compared with that of foreign advanced system and trip summaries from a point,to determine the optimal design of the general direction of the.Select the current domestic typical high-rise public buildings fire water system of a full range of reliability calculation,and according to the calculation results to analyze the reliability of each component of the system,to optimize the design of the weak reliability of components,only the components reliability reached for the fire water system to better protect the high-rise public buildings.This paper mainly on the way of water supply were detailed comparison,and to study the effect of all kinds of water supply mode on the reliability of the system,and expounds the high-rise public buildings fire pool for the necessity of the separation,and is based on the distribution of tank are introduced in detail;a strong focus on the necessity of fire system self check;anti overpressure,pressure and pressure relief devices are to meet the necessary conditions for the safety standards of the fire hydrant system pressure and flow.In high-rise public buildings fire occurred in the early stage of the use of automatic sprinkler system to extinguish the fire,if the fire has not changed before can not be timely control the fire,the fire will be the building caused serious damage,so the early fire is very key,which requires strict calculation of the various components of the technical parameters in the design of the wet sprinkler system.The alarm valve ring of water supply pipeline valve distribution of fire hydrant system in the appropriate improvement;the nozzle in the regional distribution of should is evenly distributed;the actual distance to the nozzle check calculation,the method of calculation used is"rectangular area of a point by point method".
