Existing technology, glass-magnesium composite heat preservation pipeline commonly used in air conditioning system, fire fighting and smoke exhaust system of general civil buildings. In engineering applications, the air duct is sometimes connected with the air valve. However, the connection structure is not standardized, usually temporary site installation, less prefabrication work, large workload, high labor costs, difficult construction personnel, high labor intensity, so the total construction period is long, production and installation construction. There is an urgent need for an air duct and valve structure with good technical results.

　　濟南螺旋風(fēng)管清洗的目的主要包括以下四個方面:

　　The purpose of cleaning spiral air duct in Jinan mainly includes the following four aspects:

　　1. 空調(diào)長時間運行后，大量的灰塵會積聚在風(fēng)道內(nèi)。如不及時清理，通風(fēng)系統(tǒng)容易受到污染，使空調(diào)無法提供良好的空氣;

　　1. After long-term operation of air conditioning, a large amount of dust will accumulate in the duct. If not cleaned in time, the ventilation system is vulnerable to pollution, so that air conditioning can not provide good air;

　　2. 積累的灰塵和適當(dāng)?shù)臏囟群蜐穸仍陲L(fēng)道將提供必需的營養(yǎng)物質(zhì)生活的細菌,也成為細菌和微生物繁殖的天堂,將疾病傳播的來源形式,使人容易患呼吸道疾病或過敏等不適反應(yīng);

　　2. Accumulated dust and appropriate temperature and humidity will provide essential nutrients for living bacteria in the airway, and also become a paradise for bacteria and microorganisms to multiply. It will spread the source of disease and make people susceptible to respiratory diseases or allergies and other uncomfortable reactions.

　　3.風(fēng)道內(nèi)大量積灰會降低機組容量，影響空調(diào)制冷效果，從而造成能量損失;

　　3. A large amount of dust accumulated in the air duct will reduce the unit capacity, affect the refrigeration effect of air conditioning, thus causing energy loss.

　　4. 定期清洗可提高空調(diào)的使用壽命。

　　4. Regular cleaning can improve the service life of air conditioners.

　　管尺寸的簡單的計算,都有一個相應(yīng)的公式,管處理如下:濟南管加工尺寸=高溫管空氣/風(fēng)速,可以再打來,耐高溫硅膠軟管濟南螺旋風(fēng)管主要由玻璃纖維布,非燃性高分子材料,高溫硅橡膠,高彈性線和線的5。其制造工藝為高溫硫化膠。而螺旋翼緣通風(fēng)管，其為螺旋薄壁管，是采用金屬帶材料盤管。

　　Simple calculation of pipe size, there is a corresponding formula, pipe processing as follows: Jinan pipe processing size = high temperature pipe air/wind speed, can call again, high temperature silicone hose Jinan spiral duct is mainly made of glass fiber cloth, non-flammable polymer materials, high temperature silicone rubber, high elastic line and line 5. Its manufacturing process is high temperature vulcanizate. The spiral flange ventilation pipe, which is spiral thin-walled tube, is made of metal tape coil.
