Automatic sprinkler system can to a large extent, reduce the loss caused by fire. By sprinkler sprinkler system, alarm valve, water flow alarm device (water flow indicator or pressure switch), and other ponents, as well as the set of pipes, water supply, and in the event of a fire water spray automatic fire extinguishing system. This design is the area of a known simplified the design of the automatic sprinkler system. To forecast system of nozzles and piping, starting with the most unfavorable point of nozzle, through the selection and calculation of parameters using d Lev calculation and continuous correction of pipe diameter, flow and pressure, all the pipe sections and eventually determine the dust and flow of fire pump, and reasonable selection of pipe and nozzle, a qualified fire extinguishing system design. Keywords: automatic water spray fire extinguishing system。 the most disadvantage ; Shievieliev F A formula 防火防爆課程設(shè)計(jì) 1 目錄 1 自動(dòng)噴水滅火系統(tǒng)簡(jiǎn)介 ............................................ 2 2 閉式自動(dòng)噴水滅火系統(tǒng)設(shè)計(jì) ........................................ 3 系統(tǒng)應(yīng)用場(chǎng)所 ............................................... 3 確定所設(shè)計(jì)的建、構(gòu)筑物的火災(zāi)危險(xiǎn)等級(jí) ....................... 3 設(shè)計(jì) 題目的確定 ............................................. 4 確定設(shè)計(jì)和計(jì)算所需的基本參數(shù) ............................... 4 3 噴頭和管網(wǎng)布置 .................................................. 6 噴頭的選擇和布置 ........................................... 6 系統(tǒng)管網(wǎng)的選擇及其布置。 ................................... 6 4 管網(wǎng)水力的計(jì)算 .................................................. 8 水力計(jì)算公式 ............................................... 8 舍維列夫公式 ............................................... 9 舍維列夫計(jì)算法 ........................................
