在工程應用中，對通風管道非常重視，對于管道本身的潔凈度、氣密性提得很高，因為凈化空調中山東通風管道內承受的風壓比普通空調成倍地增高，所以大家不能不重視。凈化空調系統通風管道的制作有一定的環境要求，下面來講講怎么回事。

In engineering application, great importance is attached to the ventilation pipeline, and the cleanliness and air tightness of the pipeline itself are highly improved. Because the air pressure borne by Shandong ventilation pipeline in the purification air conditioning is twice as high as that of ordinary air conditioning, people cannot ignore it. There are certain environmental requirements for the production of the ventilation pipes of the purification air-conditioning system. Let's talk about how it works.

對凈化空調系統通風管道制作與安裝的要求，除滿足一般空調系統對通風管道的要求外，還應滿足不同潔凈度等級的系統對通風管道的制作與安裝要求。

The requirements for the fabrication and installation of ventilation ducts of the purification air conditioning system shall not only meet the requirements for ventilation ducts of general air conditioning systems, but also meet the requirements for the fabrication and installation of ventilation ducts of systems with different cleanliness levels.

1、在凈化空調系統中，其法蘭墊應為不產塵、不宜老化和具有一定強度和彈性的材料，厚度為5～8mm，不得采用乳膠海綿；并不允許直縫對接連接，接縫采用梯形連接嚴禁在墊料表面涂涂料；其螺母宜在同一側法蘭接口的連接應嚴密、牢固。墊片不應凸入管內，亦不宜突出法蘭外。

1. In the purification air conditioning system, the flange gasket shall be made of materials that do not produce dust, are not suitable for aging, and have certain strength and elasticity. The thickness is 5-8mm, and latex sponge shall not be used; Straight seam butt connection is not allowed. Trapezoidal connection is adopted for the joint. It is strictly prohibited to paint the surface of the padding; The connection of its nut at the flange interface on the same side should be tight and firm. The gasket shall not protrude into the pipe or out of the flange.

2、通風管道空氣溫度70度以下,法蘭墊應為橡膠板,閉孔海棉橡膠板密封膠帶或其他彈性閉孔材料。

2. When the air temperature of the ventilation pipe is below 70 ℃, the flange gasket shall be rubber plate, closed cell sponge rubber sheet sealing tape or other elastic closed cell materials.

3、通風管道空氣溫度70度以上,法蘭墊應為石棉橡膠板。

3. The air temperature of the ventilation pipe is above 70 ° C, and the flange gasket shall be asbestos rubber plate.

通風管道制作和清洗的場地應在相對較封閉、無塵和清潔的環/考試大/境中進行，地面應鋪設干凈不產塵的保護材料（如橡膠板或塑料板等），應配備良好的通風設施，保持良好的通風狀態，并經常清掃保持場內干凈無塵。

The site for fabrication and cleaning of ventilation pipes shall be in a relatively closed, dust-free and clean environment. The ground shall be paved with clean and dust-free protective materials (such as rubber plates or plastic plates). Good ventilation facilities shall be provided to maintain good ventilation, and the site shall be cleaned frequently to keep it clean and dust-free.

通風管道清洗時（包括槽、罐內清洗）應在具有良好通風狀態時方可進行。潔凈度等級N1～N5級的通風管道系統，不得采用按扣式咬口。通風管道及部件的各個縫隙處應利用密封膠密封；通風管道內表面應清洗，直至用白綢布檢查無油污和浮塵后，再用薄膜將開口處封閉。更多相關內容就來我們網站http://www.xyphw.com進行咨詢吧！

The ventilation pipe cleaning (including tank and tank cleaning) shall be carried out when it is in good ventilation condition. The ventilation pipeline system with cleanliness level of N1~N5 shall not adopt snap joint. Sealants shall be used to seal all gaps of ventilation pipes and components; The inner surface of the ventilation pipe shall be cleaned until there is no oil stain and floating dust with white silk cloth, and then the opening shall be closed with film.
