在工程应用中，对通风管道非常重视，对于管道本身的洁净度、气密性提得很高，因为净化空调中山东通风管道内承受的风压比普通空调成倍地增高，所以大家不能不重视。净化空调系统通风管道的制作有一定的环境要求，下面来讲讲怎么回事。

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.

对净化空调系统通风管道制作与安装的要求，除满足一般空调系统对通风管道的要求外，还应满足不同洁净度等级的系统对通风管道的制作与安装要求。

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、在净化空调系统中，其法兰垫应为不产尘、不宜老化和具有一定强度和弹性的材料，厚度为5～8mm，不得采用乳胶海绵；并不允许直缝对接连接，接缝采用梯形连接严禁在垫料表面涂涂料；其螺母宜在同一侧法兰接口的连接应严密、牢固。垫片不应凸入管内，亦不宜突出法兰外。

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、通风管道空气温度70度以下,法兰垫应为橡胶板,闭孔海棉橡胶板密封胶带或其他弹性闭孔材料。

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、通风管道空气温度70度以上,法兰垫应为石棉橡胶板。

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

通风管道制作和清洗的场地应在相对较封闭、无尘和清洁的环/考试大/境中进行，地面应铺设干净不产尘的保护材料（如橡胶板或塑料板等），应配备良好的通风设施，保持良好的通风状态，并经常清扫保持场内干净无尘。

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.

通风管道清洗时（包括槽、罐内清洗）应在具有良好通风状态时方可进行。洁净度等级N1～N5级的通风管道系统，不得采用按扣式咬口。通风管道及部件的各个缝隙处应利用密封胶密封；通风管道内表面应清洗，直至用白绸布检查无油污和浮尘后，再用薄膜将开口处封闭。更多相关内容就来我们网站http://www.jntfgd.com进行咨询吧！

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.
