        大家都知道与电加热器、防火阀连接的风管要求采用不燃材料,是防止高温引起火灾或火灾发生时火焰越过防火阀而造成更大的损失,风管安装加工应注意的几大问题具体如下:

          Everyone knows that the air ducts connected with electric heaters and fire valves require the use of non-combustible materials to prevent the fire caused by high temperature or fire from causing greater losses when the flame crosses the fire valves. Several major problems that should be paid attention to in the installation and processing of air ducts are as follows:

          1、通风管道在运输过程应有防止损伤风管的保护措施。

          1. Ventilation pipes should be protected against damage during transportation.

          2、榫接风管的连接在榫口处涂胶粘剂,是为增强接头处的强度。

          2. The connection of tenon-joint air duct is coated with adhesive at the tenon-joint to enhance the strength of the joint.

          3、当风管采用地面预组装后架空安装时,限制预组装的长度是为了遮免风管因自重产生的弯曲而破坏构件接口。

          3. When air ducts are installed overhead after ground pre-assembly, the length of pre-assembly is limited in order to prevent the bending of air ducts caused by self-weight from destroying component interfaces.

          4、玻璃纤维复合板风管端口为切割面时,在装配法兰连接件前应将管端切口面用胶带或胶液进行封堵,才能防止玻璃纤维外露和飞散。

          4. When the end of glass fiber composite board air duct is cut face, before assembling flange connector, the end of the pipe should be sealed with tape or glue to prevent the glass fiber from exposing and flying away.

          5、非法兰连接的玻璃纤维复合板风管垂直安装的支撑件制作与安装的方法。

          5. The method of making and installing the supporting parts for the vertical installation of the glass fibre composite board air duct connected by illegal blue.

          6、竖井内通风管道垂直安装,由于空间少,又不便于以后检修,故风管一般采用外套角钢法兰连接以增加连接点的牢固程度和强度,并把法兰作成“井”形,吊筋直接吊在角钢法兰的吊耳上而不另设支撑件。

          6. Vertical installation of ventilation pipes in vertical shaft, due to the lack of space and the inconvenience of later maintenance, so the air duct generally adopts the outer angle steel flange connection to increase the firmness and strength of the connection points, and the flange is made into a "well" shape, and the suspension bar is directly suspended on the lifting lug of the angle steel flange without additional supporting parts.

          风管安装加工是将法兰的槽口套插在风管管板的端头,用胶粘剂粘接。如果其间没有过盈量,槽口和风管端面插入时会有一定的间隙,使其无法粘为一体。

          The installation and processing of the air duct is to insert the slot sleeve of the flange into the end of the air duct plate, and to bond it with adhesive. If there is no interference between them, there will be some gap between the groove and the end face of the air duct when inserting, which makes it impossible to stick together.
