It figured out that there was flow of water not only in the calculated pipeline but also in other pipelines and that diameters of hydrant ringed piping should be ensured after calculation 认为某一点着火后，不仅是计算管路有水流通过，其他管路也有水流经过，消火栓环状管网的管径应通过计算确定。
Fire protection of buildings is the most important of buildings water supply and drainage engineering design . fire hydrant system is the basic and extensively adopted technique of buildings fire protection at present in our country 建筑消防是建筑给排水工程设计中最重要的部分，目前在我国室内消火栓灭火系统又是建筑消防最基本、普遍采用的方式。
According to the code for design of extinguisher disposition in buildings , portable fire extinguisher box , in which there are necessary number of portable ammonium phosphate powder extinguishers , will be installed under every hydrant box 在本建筑内按"建筑灭火器配置设计规范"在每个消火栓箱下设手提式灭火器箱,箱内设有必要数量的磷酸铵盐手提式灭火器
Article 21 any unit or individual shall not damage or arbitrarily use , dismantle and stop using fire control facilities and devices , and shall not bury and occupy hydrant , occupy fire prevention space and block fire control passageway 第二十一条任何单位、个人不得损坏或者擅自挪用、拆除、停用消防设施、器材，不得埋压、圈占消火栓，不得占用消防间距，不得堵塞消防通道。
This paper probes into some divergent problems in the fire - control design , such as the distribution of high position fire protection water tank in the high buildings , the fire - hydrant configuration and fire - control design of the high - rise building with commercial service center 就消防设计工作中一些有分歧的问题,如高层建筑群中高位消防水箱的设置、消火栓的配置、设有商业服务网点的高层住宅消防设计等问题进行了探讨。
It is more accurate than traditional method at the aspect of calculating head loss , pipe flow and node pressure of hydrant . this mathematic model can also be used in the inside and outside of water supply piping calculation and it is excel hardy cross - piping calculation 该方法在计算水头损失、管段流量、消火栓节点压力等方面比传统方法要更加准确，也可被借鉴到室内或室外的给水管网计算，并优于常见的哈代-克罗斯管网平差方法。
As far as the water supply and drainage of buildings are concerned , these new developments include the reformation of water meter reading systems and drainage way of toilet and kitchen , the improvement of hydrant systems and automatic sprinkler systems , the application of drinking water systems 在建筑给水排水方面，主要表现为水表抄表系统和厨卫排水方式的变革、消火栓系统和自动喷淋灭火系统的不断完善以及直饮水系统的出现。

This company in accordance with state standard gb14561 - 93 produces hydrant boxes in 3 models : sg24a 、 sg24b 、 sg24c 、 and may provide corresponding hydrants , hose , gun and hose adaptors . it also fabricates extinguisher - hydrant combined boxes 本公司生产的消火栓箱,按国家标准gb14561 - 93制造生产,共有3个规格型号: sg24a 、 sg24b 、 sg24c ，并可按客户要求配备相应规格的消火栓、水带、水枪、水带接扣等部件，并可承接各类消火栓、灭火器箱的组合箱。
On this base , the paper gave a new way of hydraulic calculation according to the ringed hydrant piping characteristic that there is one region of fire at same time and there is one sprinkle region of hydrant system in the buildings . this method used fem to build mathematic model 在此基础上，针对建筑物同时着火点只有一处而消火栓系统只有一处出水的情况下环状管网的水流特点，提出了一种新的环状管网的水力计算方法，利用有限单元法建立数学模型。
