风道系统阻力平衡的几大逻辑关系

  一、济南通风管道工程中的防火阀的操作装置原理

  I. the operating principle of the fireproof valve in the ventilation and smoke exhausting equipment

  RONGDUANQIXINGANDINGDUANXUNCHANGKAZHUFAZHOU(YEPIANZHOU)SHANGDECHABAN,SHIFAMENZAIYUCHANGKAIXINGTAI。DANGFASHENGHUOZAIHOU,DANDAONEIQIXUANLIANGDUSHENGDAORONGDUANQIYIRONGDUANYIRONGPIAN,JIBENGHUANGCUJINXINGAN,TUOKAICHABAN,FAZHOUSHOUNIULIBENGHUANGZUOYONGERZHUANDONGKAIFANGFAMEN。

  The end of the fuse core rod is usually stuck on the fork plate of the valve shaft (blade shaft) so that the valve is in normally open form. When the fire occurs after the cyclone in ballistic rise to measure fuse easy fuse fusible film, which promote the core rod and spring, when the valve plate, shaft torsion spring and rotating the valve open.

  ANZHUANGZHENGZAIDIFANGKONGDIAOJIFENGDAOLINGSUIZHONG,RENWUYUANLISHIJIYIRONGHEJINDELIANGDUZHANGWO,SHIYONGZHONGLIZUOYONGHEBENGHUANGZUZHIDEZUOYONGKAIFANGFAMEN。DANGHUOJINGFASHENGSHI,HUOMIAORUQINFENGDAO,DIWENSHIFAMENSHANGDEYIRONGHEJINRONGJIE,HUOZHESHIHUIYIHEJINFASHENGXINGBIANSHIFAMENZHUDONGKAIFANG,YONGLAIFENGDAOYUFANGHUOFENQUGUANCHUANDECHANGHE。

  Install air duct is local air conditioning system, task principle is a measure of the fusible alloy pole master, open valve using gravity and spring organization. When the fire broke out, the flames of intrusion duct, low temperature fusible alloy melting on the valve, or the memory alloy is deformed so that the valve open, to the air duct and the fire district through occasions.

  XUNCHANGFENGLIANGDAXIAORUXUDIAOJIE,KETONGGUOYUFAZHOU(YEPIANZHOU)LIANDONGDEQUBINGDIAOJIEFAMENKAIDU,DIDAYAOQIUSHIYOUDIEMULIUDONGQIDIWEI。QUBINGYUCHABANJIECHUCHUZHIYOUHUANCHI,FANGZHIHUAXINGOUHEHOU,FAMENKAIDUDIAODINGHOUYIBAOCHIMEIYOUBIAN。

天天乐棋牌  Ordinary air volume, such as the need to adjust, can be connected with the valve shaft (blade axis) crank to adjust the valve opening, arrived at the request by the butterfly mother flow its position. The crank is connected with the fork plate to prevent the sliding coupling. After the valve is opened, the valve is opened and adjusted to remain unchanged.

  二、风道系统阻力平衡自动计算的执行过程基本延用常规设计的计算步骤,主要如下:

天天乐棋牌  Two, air duct system resistance balance automatic calculation of the basic implementation process using conventional design calculation steps are as follows:

  1.JIANGGEJIEDIANJIANDELUOJIGUANXI、GUANDUANDEXIANGGUANCANSHUYICISHURUBINGBAOCUN,RANHOUGENJUJISHUYAOQIUCHUBUXUANDINGGEGUANDUANDEJIADINGFENGSU

  1., the logical relation among nodes and the related parameters of pipe section are input and saved in sequence. Then, the assumed wind speed of each pipe section is selected according to technical requirements

  2.GENJUJIADINGFENGSUZIDONGJISUANGUANDUANDANGLIANGSHUILIZHIJINGJIZULISUNSHI

  2. calculate the equivalent hydraulic diameter and resistance loss of the pipe section automatically according to the assumed wind speed

  3.YONGJIEDIANNIXUNFAZIDONGCHAZHAOXITONGGEHUANLUDELUJINGJIZULISUNSHI,BINGQUEDINGXITONGBULIHUANLU

天天乐棋牌  3., the method of node inverse searching is used to find the path and resistance loss of each loop, and the worst loop of the system is determined

  4.DUIFEIBULIHUANLUJINXINGZIDONGZULIPINGHENG。

天天乐棋牌  4. automatic balancing of the non adverse loop.
