通風(fēng)管道是通風(fēng)體系重要組成部分，通風(fēng)管道設(shè)備體系設(shè)計(jì)目的，是要合理地處理安排空氣的活動(dòng)，在確保使用作用前提下，合理斷定風(fēng)管結(jié)構(gòu)、布局和尺寸，使體系的初投資和運(yùn)用費(fèi)用歸納較低。通風(fēng)工程是送風(fēng)、排風(fēng)、除塵以及排煙體系工程統(tǒng)稱(chēng)。

The ventilation pipe is an important part of the ventilation system, ventilation system design of pipeline equipment, is to reasonably arrange the air handling activities, in ensuring the use function under the premise of reasonable structure, determine the layout and size of the wind pipe, so that the system's initial investment and operation expenses of the low induction. Ventilation engineering is air, exhaust, dust and smoke exhaust system works collectively.

合理的通風(fēng)體系能夠確保作業(yè)場(chǎng)所空氣活動(dòng)循環(huán)，還能夠給工人一個(gè)較為舒適的呼吸環(huán)境。通風(fēng)管道設(shè)備體系設(shè)計(jì)問(wèn)題如下：

The ventilation system can ensure the reasonable workplace air circulation, also can give workers a more comfortable breathing environment. The design problem of ventilation system of pipeline equipment:

榜首，氣流安排：通風(fēng)工程氣流安排基本準(zhǔn)則是排風(fēng)口應(yīng)盡量接近有害物源或散熱設(shè)備，送風(fēng)口應(yīng)盡量的接近操作地點(diǎn)或人員經(jīng)常停留處。

The top air ventilation engineering flow arrangement arrangement: the basic criterion is the outlet should be as close as possible to the source of harmful substances or cooling equipment, the outlet should be as close to the operation place or people often stay at.

第二，風(fēng)機(jī)選型：依據(jù)風(fēng)機(jī)特性曲線能夠看出，風(fēng)機(jī)能夠在各種不同風(fēng)量下作業(yè)，風(fēng)機(jī)在特性曲線某一作業(yè)點(diǎn)上，風(fēng)機(jī)的風(fēng)壓和體系中的壓力得到平衡，就斷定體系的風(fēng)量。

Second, fan selection: Based on the characteristic curve of the fan can be seen, the fan can work in a variety of different air flow, the fan at a point of operation characteristic curve, fan wind pressure and system pressure balance, conclude that the air volume system.

第三，防火閥設(shè)置：設(shè)置防火閥的首要目的是避免火災(zāi)經(jīng)過(guò)風(fēng)管漫延。引薦采用將衛(wèi)生間的排氣支管接入排氣豎井上升六十毫米的“避免回流”措施。

Third, the fire valve setting: the primary purpose of setting fire valve is to avoid the fire spread through the wind pipe. The referral will avoid return measures to toilet exhaust pipe access exhaust shaft sixty mm rise ".

其具有結(jié)構(gòu)簡(jiǎn)單，造價(jià)低、運(yùn)轉(zhuǎn)可靠等特點(diǎn)，因?yàn)椴捎昧藦濐^進(jìn)豎井，支管和主管氣流方向相同，此部分部分的助力小，其豎井排風(fēng)的總阻力并不一定因?yàn)樨Q井面積減少以點(diǎn)而增大。

It has the advantages of simple structure, low cost, reliable operation and other characteristics, because the use of elbow into shaft, branch and charge flow direction, this part of the small power, the total resistance of the shaft exhaust is not necessarily because the area is reduced to increase the shaft.

裝置四大注意事項(xiàng);

Unit four note;

1)對(duì)于比較復(fù)雜的民用修建，在設(shè)計(jì)階段，各工種(暖通、給水排水，供電照明與修建)應(yīng)洽談好空間分隔，定出每種管道的標(biāo)高規(guī)模。一般情況下不得越出給自己規(guī)則的邊界，遇有個(gè)別管段要越界時(shí)應(yīng)與其他工程洽談。

1) for civil building complex, in the design stage, various types (HVAC, water supply and drainage, power supply and construction of professional lighting) should first negotiate good space, set the size of each pipeline elevation. Can not go beyond the boundary to their own rules in general, in a period of leave to cross should negotiate with other engineering.

2)處理各種通風(fēng)管道相碰及協(xié)調(diào)的準(zhǔn)則，一般為：“小管讓大管，有壓讓無(wú)壓”。例如，自來(lái)水管與風(fēng)管相撞，則應(yīng)當(dāng)自來(lái)水管拐彎。冷、熱水管與下水管相碰，則應(yīng)改變冷、熱水管道。

2) all kinds of ventilation pipe and collision coordination criteria for general treatment: "let the pressure get tubular bassoon, no pressure". For example, tap water pipe and air pipe collided, should turn the tap water pipe. The cold and hot water pipes and water pipes together, should change the cold and hot water pipe.

3)施工前應(yīng)設(shè)備總管的工程師，將各工種的管線，單線畫(huà)在一張平面圖上。每種管道用一種彩色筆。在各交點(diǎn)處歸納其標(biāo)高，看是否有矛盾之處，及時(shí)發(fā)現(xiàn)，將問(wèn)題處理在裝置之前。

3) equipment duct Engineer shall before the construction of the pipeline will be of various types, single picture on a graph. A color pen for each kind of pipeline. At each intersection point induces its elevation, to see if there are contradictions, in time, will deal with the problem in the prior device.

4)為了減少投資，節(jié)省空間，降低層高，有些敷設(shè)無(wú)坡度要求的管道，能夠穿梁敷設(shè)(如自來(lái)水管道，消防噴灑干管等)。

4) in order to reduce investment, save space, reduce the floor height, some non laying pipeline slope requirements, can cross beam placement (such as tap water pipelines, fire sprinkler pipe etc.).
