螺旋风管连接的基本知识你知道那些?

螺旋风管长度可根据用户需要设定,减少风管与泄漏的连接。此外,螺旋风管可采用非蓝色连接方式连接,泄漏量小,减少泄漏量可降低日常运行成本和能耗。螺旋风管接头为环形接头,接头强度远高于径向接头。因此,螺旋风管可以保证在双重工作压力下接头无裂纹。此外,由于螺旋风管强度高,规范还规定螺旋管板厚可比一般圆管板厚减少10-15。与此同时,螺旋风管的支架与吊架之间的距离也可以比一般管道的距离长。
The length of spiral air duct can be set according to user needs to reduce the connection between air duct and leakage. In addition, the spiral air duct can be connected by non blue connection, with small leakage. Reducing the leakage can reduce the daily operation cost and energy consumption. The spiral air duct joint is a ring joint, and the strength of the joint is much higher than that of the radial joint. Therefore, the spiral air duct can ensure that the joint is free of cracks under double working pressure. In addition, due to the high strength of spiral duct, the specification also stipulates that the thickness of spiral duct plate can be reduced by 10-15 compared with that of general circular duct plate. At the same time, the distance between the support and hanger of spiral air duct can also be longer than that of general pipeline.
安装螺旋风管的方法有很多。订购时,我们先决定连接的方式,然后再决定购买。连接方法包括法兰连接方法和插座连接方法。采用法兰连接方式安装时,风管和管件的管径应相同。经插座试验,管件尺寸略小于螺旋风管管件。因此,可以计算出每个风道的规格,在安装时可以使用每个风道的准确长度,而不需要切割长度。
There are many ways to install spiral duct. When ordering, we first decide how to connect, and then decide to buy. The connection method includes flange connection method and socket connection method. When flange connection is adopted for installation, the pipe diameter of air duct and pipe fittings shall be the same. According to the socket test, the size of pipe fittings is slightly smaller than that of spiral air duct fittings. Therefore, the specification of each air duct can be calculated, and the exact length of each air duct can be used during installation without cutting length.
镀锌薄板螺旋风管基本上是螺旋风管的特点,但价格仅为螺旋风管的三分之二甚至更低。到2000年,据统计,螺旋管道在美国办公楼和地铁中的应用已经达到。法兰垫片应采用气密、弹性、耐老化的连接材料制成,厚度为3-5mm,宽度不小于10mm。风管风速测量的精度不仅取决于测量仪器的精度,还取决于使用皮托管或热球风速仪测量时仪器的支承方法和读数方法;管道垂直安装不得超过4m,单个直管道至少有两个固定点;在施工中,应按要求安装砌砖和结构管道。预埋件安装在与金属风道连接处,或要求土建单位配合堵漏,确保连接紧密。管道和管件的公差配合应一致。铜管的椭圆度和壁厚不均匀性应符合产品质量标准。目前使用的成品零件较多。
Galvanized sheet spiral air duct is basically the characteristic of spiral air duct, but the price is only two-thirds or even lower than that of spiral air duct. By 2000, according to statistics, the application of spiral pipe in American office buildings and subways had reached. The flange gasket shall be made of air tight, elastic and aging resistant connecting materials, with a thickness of 3-5mm and a width of no less than 10mm. The accuracy of air duct wind speed measurement depends not only on the accuracy of the measuring instrument, but also on the supporting method and reading method of the instrument when using Pitot tube or hot ball anemometer; The vertical installation of pipes shall not exceed 4m, and a single straight pipe shall have at least two fixing points; During construction, brickwork and structural piping shall be installed as required. The embedded parts shall be installed at the connection with the metal air duct, or the civil engineering unit shall be required to cooperate with plugging to ensure tight connection. The tolerance fit of pipes and fittings shall be consistent. The ovality and wall thickness non-uniformity of copper pipe shall meet the product quality standards. At present, many finished parts are used.
