山東通風管道加工的過程中應該盡量避免出現縱向接縫，但是不能出現橫向接縫。而且通風管道的咬口縫和四角的縫隙處，需要按照設計潔凈等級要求，然后還要采用密封膠將其堵嚴。使室內空氣滿足衛生要求和生產過程需要。建筑中完成通風工作的各項設施，統稱通風裝置。

During the processing of Shandong ventilation pipes, longitudinal joints should be avoided as much as possible, but transverse joints should not occur. In addition, the seam of the ventilation pipe and the joints at the four corners need to be sealed tightly with sealant according to the design cleanliness level requirements. Ensure that indoor air meets hygienic requirements and production process needs. The various facilities that complete the ventilation work in a building are collectively referred to as ventilation devices.

一、通風工程的排風口裝置：

1、 Exhaust device for ventilation engineering:

衛生間排風口應盡量裝置在馬桶之上。其它由主機連出的排風管路應盡量短直，咱們主張管路不出衛生間，這樣可以使新風與排風充沛混合后置換循環排出，防止通風死角。排風口分側排、直排兩種形式，排風口裝置要牢固，風口緊貼墻面或吊頂。

Toilet exhaust outlets should be installed above the toilet as much as possible. Other exhaust pipes connected from the main engine should be as short and straight as possible. We advocate that the pipes should not go out of the bathroom, so that fresh air and exhaust air can be fully mixed and replaced for circulation and exhaust, preventing ventilation dead spots. The air outlet is divided into two types: side exhaust and direct exhaust. The air outlet device should be firm, and the air outlet should be close to the wall or ceiling.

二、通風工程進風器的裝置：

2、 Installation of air intakes for ventilation works:

進風器方位一般主張挑選在住宅的窗戶下方（間隔地上不小于50cm）、暖氣上方處等處，便利裝置與保護，并且不影響室內物品的擺放，要盡量防止死角，較好的方式是進風器與排風口成對角線使新風與室內污濁空氣構成對流循環，防止室內空氣出現通風死角。

The orientation of the air inlet is generally recommended to be selected below the windows of the residence (with a spacing of not less than 50cm above the ground), above the heating, etc., to facilitate installation and protection, and not affect the placement of indoor items. It is necessary to prevent dead corners as much as possible. A better way is to diagonally align the air inlet and exhaust outlet to form a convective circulation between fresh air and indoor dirty air, to prevent the occurrence of ventilation dead corners in the indoor air.

進風器的裝置要牢固，室外防雨部分可運用自攻絲與防水玻璃膠（特殊情況可運用防水泡沫膠）進行固定，但方向不行歪斜避免影響防雨作用。室內部分可運用中性玻璃膠或自攻絲進行固定，風口里外部分都應緊貼墻面。

The device of the air inlet should be firm. The outdoor rain proof part can be fixed with self tapping and waterproof glass glue (waterproof foam glue can be used in special cases), but the direction should not be skewed to avoid affecting the rain proof effect. The indoor part can be fixed using neutral glass adhesive or self-tapping, and the inner and outer parts of the air outlet should be tightly attached to the wall.

通風管道加工系統就是實現通風這一功能，包括進風口、排風口、送風管道、風機、降溫及采暖、過濾器、控制系統以及其他附屬設備在內的一整套裝置。以上就是為您講解的部分內容，您還有什么事項就來咨詢我們http://www.okok0579.com吧！
