专注通风管道加工·排烟罩

1、支吊托架、规格、间距必须符合设计要求，风口阀门等处不得设置吊杆， 风管吊杆必须牢固、位置标高及走向符合设计要求，部件安装要求方向正确，操作方便，防火阀检修口必须便于操作。
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新风管采用无法兰风管连接方式，无法兰加工，无法兰连接风管的接口采用机械加工尺寸正确，形状规则，接口严密，插条式法兰连接， 插条用0.8mm镀锌钢板下料咬形。插条两端压接两平面各20mm，风管安装时把插条与风管连接;风管吊装好时，用打高分子密封胶密封严密.
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、风口安装位置正确，外露部分子整美观排列整齐一致。粘贴保温钉前应将风管壁上尘土、油污，将 粘贴剂分别涂抹在风管和保温钉上，稍干后再将其粘上，保温钉粘贴密度12只/m2。何温板下料及铺设:下料要准确，切割要平齐，搭接要严密、平整，散材不 可外露，板材纵横缝错开。
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、漏光及漏风量测试

4, leakage and leakage test
5、漏光法检测应采用光线对小孔的强穿透力，对系统风管严密程度进行了检测方法，采用具有一定强度的光源。如低压灯lOOW带保护罩的低压照明灯，或者其 它低压光源。低压风管每lorn不应大于2处且lOOm接缝平均不应大于16处，中压系统每10m不应超1处，且100m接缝平均不应大于8处，都为合格 漏光，检测 中如发现条缝形漏光的应及时进行密封处理。
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、漏风量测试应采用检验合格的专用测量仪表或采用符合现行标准(流量测量节流装置)规定的计量元件搭设的测量装置。漏风管测试装置可采用风管 式或风室式。风管式测试装置采用孔板作计量元件，风室式测试装置采用喷嘴作计量元件，后测出的实测值与设计给定的数值不应小于10%为合格。
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.
