廚房通風排煙管道的裝置仍是有一些細節(jié)是需求留意的，廚房通風排煙管道是小區(qū)內(nèi)部或者是餐廳食堂必要存在的一個硬件設(shè)備。下文就這些細節(jié)進行具體的介紹。

There are still some details about the installation of kitchen ventilation and smoke exhaust pipe. The kitchen ventilation and smoke exhaust pipe is a necessary hardware equipment in the community or in the canteen. These details are described in detail below.

（1）整個通風系統(tǒng)規(guī)劃采用漸縮管均勻送風者，圓形風管按均勻直徑，矩形風管按均勻周長履行相應(yīng)標準項目其人工乘以系數(shù)2.5。

(1) If the whole ventilation system is planned to use the tapered pipe for uniform air supply, the circular air duct shall be of uniform diameter, and the rectangular air duct shall perform the corresponding standard items according to the uniform circumference, and its labor shall be multiplied by the coefficient of 2.5.

（2）鍍鋅薄鋼板風管項目中的板材是按鍍鋅薄鋼板編制的，如規(guī)劃要求不必鍍鋅薄鋼板者，板材能夠換算，其他不變。

(2) The plates in the galvanized steel sheet air duct project are prepared according to the galvanized steel sheet. If the planning requires that the galvanized steel 

（3）風管導流葉片不分單葉片和香蕉形雙葉片均履行同一項目。

(3) The air duct guide vane shall perform the same project regardless of single blade and banana double blade.

（4）如制造空氣幕送風管時，按矩形風管均勻周長履行相應(yīng)風管標準項目，其人工乘以系數(shù)3，其他不變。

(4) For example, when manufacturing the air curtain air supply duct, the corresponding air duct standard items shall be performed according to the uniform circumference of the rectangular air duct, and the labor shall be multiplied by the coefficient of 3, while others remain unchanged.

（5）薄鋼板通風管道制造裝置項目中，包含彎頭、三通、變徑管、天圓地方等管件及法蘭、加固框和吊托支架的制造用工、但不包含過跨風管落地支架，落地支架履行設(shè)備支架項目。煙道過于狹窄，大排量煙機一般每分鐘排風量會在13立方米左右，過于狹小的煙道會造成排風受阻，氣流回轉(zhuǎn)，風壓加大產(chǎn)生的噪音，還有就是要檢查一下看看排煙管是否深入煙道過多，在墻壁或天花板上砌上消音磚，或涂上消音漆以及安裝隔音門等。

(5) The manufacturing equipment project of sheet steel ventilation pipe includes the manufacturing labor of elbow, tee, reducer, round place and other pipe fittings and flanges, reinforcing frame and lifting support, but does not include the floor support of over span air duct. The floor support performs the equipment support project. The flue is too narrow. Generally, the exhaust air volume of large displacement ventilator will be about 13 cubic meters per minute. Too narrow flue will cause obstruction of exhaust air, rotation of air flow and noise caused by increased air pressure. In addition, it is necessary to check whether the smoke exhaust pipe goes too deep into the flue, build silencing bricks on the wall or ceiling, paint silencing paint and install sound insulation doors.
