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.
1、 Exhaust device for ventilation engineering:
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.
2、 Installation of air intakes for ventilation works:
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.
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.
The ventilation pipe processing system is a complete set of devices that achieve the function of ventilation, including air inlets, exhaust outlets, air supply pipes, fans, cooling and heating, filters, control systems, and other auxiliary equipment.
