關于通風防排煙設備裝置質量有什么請求?下面由順發通風管道的相關人員引見一下：
What is the requirement for the quality of ventilation, smoke prevention and exhaust equipment? The following is introduced by the relevant personnel of the ventilation pipeline.
1、支吊托架、規格、間距必需契合設計請求，風口閥門等處不得設置吊桿， 風管吊桿必需結實、位置標高及走向契合設計請求，部件裝置請求方向正確，操作便當，防火閥檢修口必需便于操作。
1. The brackets, specifications and spacing of supporting cranes must meet the design requirements. No suspenders shall be installed at the vent valves and other places. The Suspenders of air ducts must be strong, elevated and aligned with the design requirements. The components and devices shall request the correct direction and operate conveniently. The fire valve overhaul ports must be easy to operate.
2、本工程小于630mm新風管采用無法蘭風管銜接方式，無法蘭加工，無法蘭銜接風管的接口采用機械加工尺寸正確，外形規則，接口緊密，插條式法蘭銜接， 插條用0.8mm鍍鋅鋼板下料咬形。插條兩端壓接兩平面各20mm，風管裝置時把插條與風管銜接;風管吊裝好時，用打高分子密封膠密封緊密.
2. The new air ducts less than 630 mm in this project are connected by non-blue air ducts and can not be processed by blue air ducts. The interfaces of non-blue air ducts are machined correctly with correct dimensions, regular shapes, compact interfaces, insert flange connection and 0.8 mm galvanized steel strip undercut. The two ends of the plunger are pressed into two planes of 20 mm each, and the plunger is connected with the air duct when the air duct is installed; when the air duct is hoisted, it is sealed tightly with high polymer sealant.

3、風口裝置位置正確，外露局部子整美觀排列劃一分歧。粘貼保溫釘前應將風管壁上塵土、油污肅清，將 粘貼劑分別涂抹在風管和保溫釘上，稍干后再將其粘上，保溫釘粘貼密度12只/m2。何溫板下料及鋪設:下料要精確，切割要平齊，搭接要緊密、平整，散材不 可外露，板材縱橫縫錯開。
3. The position of the tuyere device is correct, and the exposed parts are arranged beautifully and divided into different parts. Dust and oil on the wall of air duct should be removed before pasting heat preservation nails. The adhesive should be applied on the air duct and heat preservation nails separately. After a little drying, the heat preservation nails should be pasted with a density of 12 nails per m2. The blanking and laying of He Wen board: the blanking should be accurate, the cutting should be smooth, the lap should be tight and flat, the bulk material should not be exposed, and the longitudinal and transverse seams of the board should be staggered.
4、漏光及漏風量測試
4. Measurement of Leakage and Air Leakage
5、漏光法檢測應采用光線對小孔的強穿透力，對系統風管緊密水平停止了檢測辦法，采用具有一定強度的平安光源。如低壓燈lOOW帶維護罩的低壓照明燈，或者其 它低壓光源。低壓風管每lorn不應大于2處且lOOm接縫均勻不應大于16處，中壓系統每10m不應超1處，且100m接縫均勻不應大于8處，都為合格 漏光，檢測 中如發現條縫形漏光的應及時停止密封處置。
5. The light leakage method should adopt the strong penetrating force of light to the small hole, stop the detection method of the tight level of the air duct of the system, and adopt the safe light source with a certain intensity. For example, low-voltage lamp lOW low-voltage lamp with maintenance cover, or other low-voltage light source. Low pressure air duct should not be more than 2 lorn and lOOm seams should not be more than 16 uniformly, medium pressure system should not exceed 1 per 10 m, and 100 m seams should not be more than 8 uniformly, all of which are qualified light leakage. Sealing disposal should be stopped in time if strip-shaped light leakage is found in detection.

6、漏風量測試應采用檢驗合格的專用丈量儀表或采用契合現行國度規范(流量丈量節流安裝)規則的計量元件搭設的丈量安裝。漏風管測試安裝可采用風管 式或風室式。風管式測試安裝采用孔板作計量元件，風室式測試安裝采用噴嘴作計量元件，后測出的實測值與設計給定的數值不應小于10%為合格。
6. The air leakage measurement test shall adopt the special measuring instruments which are qualified or the measuring elements which conform to the current national standard (flow measurement and throttling installation) rules. Air duct or air chamber can be used for testing and installation of air leakage pipe. The orifice plate is used as the measuring element in the air duct type test installation, and the nozzle is used as the measuring element in the air chamber type test installation. The final measured value and the design given value should not be less than 10% qualified.
