1、支吊托架、規(guī)格、間距必須符合設(shè)計要求，風(fēng)口閥門等處不得設(shè)置吊桿， 風(fēng)管吊桿必須牢固、位置標(biāo)高及走向符合設(shè)計要求，部件安裝要求方向正確，操作方便，防火閥檢修口必須便于操作。
1, a supporting bracket, specifications, spacing must meet the design requirements, the air valve shall be set at the boom, boom, wind pipe must be firmly position to elevation and meet the design requirements, component installation requirements of the right direction, convenient operation, maintenance of fire valve mouth must be easy to operate.2、本工程小于630mm新風(fēng)管采用無法蘭風(fēng)管連接方式，無法蘭加工，無法蘭連接風(fēng)管的接口采用機械加工尺寸正確，形狀規(guī)則，接口嚴(yán)密，插條式法蘭連接， 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(fēng)管安裝時把插條與風(fēng)管連接;風(fēng)管吊裝好時，用打高分子密封膠密封嚴(yán)密.
2, the project is less than 630mm, and the new air pipe can not be connected by Lanfeng pipe. It has no flange processing. The connection between the flanged connection and the air duct is machined with the right size, the shape is regular, the interface is tight, the cuttings flange connection is connected, the cuttings are 0.8mm zinc plated steel sheet undercut bite. The two ends of the bar are pressed to each 20mm of the two plane, and the wind pipe is connected to the wind pipe when the wind pipe is installed. When the wind pipe is hoisted well, the seal is sealed with high polymer sealant.3、風(fēng)口安裝位置正確，外露部分子整美觀排列整齊一致。粘貼保溫釘前應(yīng)將風(fēng)管壁上塵土、油污，將 粘貼劑分別涂抹在風(fēng)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(shè):下料要準(zhǔn)確，切割要平齊，搭接要嚴(yán)密、平整，散材不 可外露，板材縱橫縫錯開。
3, the installation position of the tuyere is correct, and the appearance of the exserted part is in neat arrangement. The dust and oil stains on the wall of the wind pipe should be removed before sticking the thermal insulation nails. The applicator is applied to the wind pipe and the heat preservation nail respectively. After a little drying, the paste is sticky, and the thermal insulation nail is pasted with a density of 12 /m2. He temperature plate material and laying: the material should be accurate, the cutting should be flat, the lap should be strict and smooth, the material can not be exposed, the plate and the transverse joint are open.4、漏光及漏風(fēng)量測試

4, leakage and leakage test
5、漏光法檢測應(yīng)采用光線對小孔的強穿透力，對系統(tǒng)風(fēng)管嚴(yán)密程度進行了檢測方法，采用具有一定強度的光源。如低壓燈lOOW帶保護罩的低壓照明燈，或者其 它低壓光源。低壓風(fēng)管每lorn不應(yīng)大于2處且lOOm接縫平均不應(yīng)大于16處，中壓系統(tǒng)每10m不應(yīng)超1處，且100m接縫平均不應(yīng)大于8處，都為合格 漏光，檢測 中如發(fā)現(xiàn)條縫形漏光的應(yīng)及時進行密封處理。
5, the leakage detection method should be used for small strong light penetration, the wind system heavily tested method, using safe light with certain strength. Such as low voltage lamp lOOW with protective cover of low voltage light, or other low voltage light source. Low pressure air pipe of each lorn should not be greater than 2 and the average lOOm joint should not be greater than 16, the medium voltage system every 10m should not exceed 1, and the average 100m joint should be less than 8, are qualified for light leakage is found in the detection of slot leakage should be promptly sealed.6、漏風(fēng)量測試應(yīng)采用檢驗合格的專用測量儀表或采用符合現(xiàn)行標(biāo)準(zhǔn)(流量測量節(jié)流裝置)規(guī)定的計量元件搭設(shè)的測量裝置。漏風(fēng)管測試裝置可采用風(fēng)管 式或風(fēng)室式。風(fēng)管式測試裝置采用孔板作計量元件，風(fēng)室式測試裝置采用噴嘴作計量元件，后測出的實測值與設(shè)計給定的數(shù)值不應(yīng)小于10%為合格。
6, the test of leakage volume should be made by a qualified special instrument or a measuring device that fits the current national standard (flow measurement throttling device). Wind pipe type or wind chamber type can be used for air leakage test device. The air duct test device adopts orifice plate as measuring element, and the wind chamber test device adopts nozzle as measuring element. Finally, the measured value is not less than 10%, which is qualified for designing the given value.
