  通风管道合口衔接时有哪些留意事项?

  What precautions should be taken when joining ventilation ducts?

  通风管道的合口衔接能否胜利是整个通风管道系统装置胜利与否的关键,通风管道的合口衔接假如不合格,就会在使管道系统在运用过程中发作泄露的现象,因而,在停止通风管道的合口衔接时,我们一定要留意以下提到的留意事项。

  The success of joint connection of ventilation duct is the key to the success of the whole ventilation duct system. If the joint connection of ventilation duct is not qualified, the leakage of the pipeline system will occur in the course of operation. Therefore, when stopping joint connection of ventilation duct, we must pay attention to the following points.

  1、矩形风管直管段,不论是同一板材衔接,还是几块板材组合拼接,外表需平整、角线顺直。组合前应肃清板材切口外表的切割粉末、灰尘及杂物。

  1。 The straight section of rectangular air duct, whether connected with the same plate or several plates, should be flat in appearance and straight in angle。 The cutting powder, dust and debris on the surface of the incision should be removed before the combination。

  2、管段组合后45度角切边外部接缝,需贴铝箔胶带封合板材外壳面,每边宽度不少于20mm。用角尺、钢卷尺检查调整垂直度及对角线偏向,并契合标准请求。

  2. The outer seam of 45 degree angle trimming after pipe segment combination should be sealed with aluminium foil tape, each side width is not less than 20 mm. Verticality and diagonal deviation should be checked and adjusted with angle ruler and steel tape ruler, and conform to the standard requirements.

  3、风管的圆弧面或折线面完成下料并折压成型后,应与平面板预组合无误后在涂刷粘合剂,以保证管件的几何外形尺寸及观感。

  3. After cutting and folding the arc or folding surface of the air duct, it should be pre-assembled with the flat plate and then coated with adhesives to ensure the geometric shape, dimension and appearance of the pipe fittings.

  4、衔接组合后的管段应垂直摆放至定型前方可挪动。

  4. After joining and assembling, the pipe section should be placed vertically in front of the finalization and can be moved.

  5、铝箔复合保温风管所用粘合剂须按板材厂商认定的专用粘合剂,如另行采购品牌粘合剂,必需做衔接效果比照实验,并经监理、板材商检查、认可前方可运用。

  5。 The adhesives used for aluminium foil composite insulation ducts should be based on the special adhesives recognized by the plate manufacturers。 If the brand adhesives are purchased separately, the comparative experiment of the bonding effect must be done。 The adhesives can be used before they are inspected and approved by the supervisor, the sheet manufacturer。

  6、粘结前须预组合,检查接缝全部贴合无误再涂刷粘合剂,粘合时间控制与时节、温度及粘合剂性能有关。批量加工前应作榜样实验,肯定佳粘合时间。

  6. Before bonding, it is necessary to pre-assemble, check all the seams are adhered correctly and then brush the adhesives. The control of bonding time is related to the time, temperature and properties of the adhesives. Model experiments should be done before batch processing to confirm the best bonding time.

  我们在通风管道的合口衔接完成后,需留意对通风管道的合口衔接停止细致的检查检验,以确保通风管道的合口衔接能否紧密紧合。

  After the joint connection of the ventilation duct is completed, we should pay attention to stop careful inspection and inspection of the joint connection of the ventilation duct to ensure that the joint connection of the ventilation duct can be tightly closed.

  通风管道在城市建筑中十分的重要,特别是它的装置质量更是影响到空气的交流,影响人们的正常的“活动”,影响人们的工作效率。

  Ventilation pipeline is very important in urban buildings, especially its installation quality affects the air exchange, affects people's normal "activities" and affects people's work efficiency.

  1、做好施工前的准备工作

  1. Preparing for construction

  俗话说“磨刀不误砍柴工”,充沛的准备工作是确保风管装置质量的前提。在准备净化风管的制造时,无论是采取工厂集中制造还是现场制造方式,都必需保证场地的干净和封锁,并具有契合条件的采光和照明条件。除此外,还要对制造好的方管停止看守,尽量防止污染。

  As the saying goes, "no mistake in cutting firewood by sharpening knives", abundant preparation is the premise to ensure the quality of air duct devices。 When preparing for the manufacture of purified air ducts, it is necessary to ensure the cleanliness and blockade of the site, as well as lighting and lighting conditions in accordance with the conditions, whether by centralized factory manufacturing or on-site manufacturing。 In addition, we should stop guarding the manufactured square tubes and try to prevent pollution。

  2、风管材质的选择

  2. Selection of Air Pipe Material

  风管材质的选择,对风管的施工质量也有很大的影响。普通而言为了保证风管的重量,需采用小板厚的风管,但除此外还需求综合思索风管的尺寸和压力级别。从设计角度来看,值得留意的是一个系统能够同时存在几种对应于不同静压级别的风管板厚。

  The selection of air duct material also has a great influence on the construction quality of air duct。 Generally speaking, in order to ensure the weight of the duct, the minimum thickness of the duct is needed, but in addition, the size and pressure level of the duct need to be considered comprehensively。 From the design point of view, it is worth noting that a system can have several duct sheet thicknesses corresponding to different static pressure levels at the same time。

  3、风管的横向衔接

  3。 Horizontal Connection of Air Pipes

  风管的横向衔接有一定考究,这种衔接方式能够说是是持续风管长度的一种手腕,还具备加强刚度及坚持风管准确地横向尺寸的作用。通常横向衔接的方式是角钢法兰衔接,这种衔接方式取决于壁厚,更取决于衔接品种及板壁加固方式。

  The horizontal connection of air duct has a certain degree of sophistication。 This connection mode can be said to be a wrist for the continuous length of air duct。 It also has the function of strengthening stiffness and insisting on the accurate lateral dimension of air duct。 Generally, the lateral connection mode is angle steel flange connection, which depends on the thickness of the wall, but also depends on the type of connection and the way of plate wall reinforcement。

  4、风管的纵向缝接合

  4。 Longitudinal seam joint of air duct

  风管的纵向缝接合方式能够依据实践状况,选择对应的方式。在中、低压风管中常常运用扣式咬口衔接,关于矩形风管,结合咬口运用无任何压力级别,因而运用扣式咬口能够俭省一道翻边工序,目前大多数的风管纵向缝接合都采用了扣式咬口。关于立缝和封盖式立缝能够运用铆钉、自攻螺丝、点焊、压凸凹痕等办法紧固。

  The longitudinal joint mode of air duct can be selected according to the practice. Button bite joint is often used in middle and low pressure air ducts. For rectangular air ducts, there is no pressure level in combination with the bite. Therefore, the use of buckle bite can save a flanging process. At present, buckle bite is used in most longitudinal seam joints of air ducts. The vertical seam and capping vertical seam can be fastened by rivet, tapping screw, spot welding and indentation.

  5、风管的寄存

  5. Storage of air ducts

  预制好的风管,是必需要做好寄存工作,以免遭到二次污染。可将管口用塑料布等密封资料封住,然后将风管分门别类堆放好。在运用风管前,要留意停止彻底的清洗工作,肯定板材外表无腐蚀,枯燥后不吸尘。

  Prefabricated air ducts are necessary to do a good job of storage, in order to avoid secondary pollution. The nozzle can be sealed with sealing materials such as plastic cloth, and then the air ducts can be classified and stacked. Before using the air duct, pay attention to stop the thorough cleaning work. Make sure that there is no corrosion on the surface of the sheet and no dust absorption after dryness.
