通風(fēng)管道的作用是使加速空氣的循環(huán)，幫助室內(nèi)的空氣的循環(huán)，降低有害氣體和溫室氣體的濃度的一種基本設(shè)施，具有一定的防火性能，在輸送有害氣體時有一定的抵御性能。

　　The ventilation pipe is the role of the accelerating air circulation and help the indoor air circulation, reduce the concentration of harmful gas is a kind of basic facilities and greenhouse gases, has certain fire performance, the performance of the protection in the transport of harmful gases.

　　螺旋式通風(fēng)管道作為一種新型的風(fēng)管施工工藝，其優(yōu)勢不言而喻、美觀、強度大、機械主動化水平高、加工制造速度快以及能削減裝置任務(wù)量，大大進步了任務(wù)效率等。

　　Spiral type ventilation pipe as a new type of wind pipe construction technology, its advantage is self-evident, beautiful appearance, high strength, high degree of automation, mechanical processing speed and can reduce device workload, greatly improve the efficiency of the task.

　　外觀質(zhì)量高。成形后的風(fēng)管內(nèi)壁潤滑，外壁流利;風(fēng)管強度大。由于外壁咬口構(gòu)成的螺旋線棱筋平均散布，起到一個平均增強筋的效果，其單元強度大于通俗咬口式風(fēng)管;

　　High quality appearance. The inner wall of the air pipe is lubricated and the outer wall is fluent; the air duct is strong in intensity. Because of the average dispersion of the spiral ribs of the screw formed by the outer wall, the strength of the reinforcing bar is stronger than that of the popular bite type wind pipe;

　　風(fēng)管密封功能優(yōu)越。由于是機械加工，能削減報酬操作掉誤，確保風(fēng)管緊密，漏風(fēng)量遠小于現(xiàn)行標(biāo)準(zhǔn)規(guī)則值;資料用量削減。

　　The wind pipe sealing function is superior. Due to mechanical processing, the utility model can reduce the remuneration, operate the mistake, ensure the tight air pipe, and the air leakage is much smaller than the current standard rule value; the data consumption is reduced.

　　因為螺旋式風(fēng)管單元強度大于通俗風(fēng)管，故同類規(guī)格風(fēng)管所用的卷材厚度可以減小一個型號，且風(fēng)管節(jié)長比通俗咬口式風(fēng)管大，相同長度的風(fēng)管節(jié)口數(shù)目分明削減。

　　Because the spiral wind pipe unit strength is greater than the popular wind, the wind pipe specifications with similar membrane thickness can be reduced to a model, and the wind pipe is longer than the popular bite type wind pipe, the same length of the wind pipe port number clear cut.

　　我們愿以佳的服務(wù)意識，迎接八方來客，誠懇與國內(nèi)外各界朋友精誠合作，共創(chuàng)美好的前程。歡迎大家前來參觀洽談!

　　We would like to serve the eight guests with the best sense of service, and sincerely cooperate with friends from all walks of life at home and abroad for a better future. Welcome to visit and negotiate!
