The function of a square and round ventilation pipe?

　　With the rapid development of world science and technology, processing technology has become increasingly familiar to people, green manufacturing has received high attention, and the manufacturing of ventilation pipes has also reached a new stage. So what should we pay attention to during use?

　　 Ventilation pipe Tianyuan difang Its main function is to connect square and round pipes. The shapes of the lower and upper parts of the pipe fitting are round and square. Generally applicable to special structural components. Ventilation pipes have flat bottoms, curves, and conical shapes. For example, the connection between circular ventilation pipes and fan outlets, air conditioning units and fan inlets. This kind of welded pipe fitting is widely used in many industries, such as the connection of anti-corrosion steel pipe systems, and some large welded structural parts, but it is more widely used in fan and ventilation and air conditioning systems.

　　When using the ventilation pipe Tianyuan difang, first draw a straight line, and draw a vertical line segment at one end, taking the height of Tianyuan. Then set the length proportionally on the line segment. Then, using the hypotenuse projection length on the top view as the base, the hypotenuse length of the triangle is drawn, which is the actual length. In this figure, the line segments required for the corners are drawn. Do the same and draw the required line segments for the four corners. Ventilation pipes are metal or composite pipes used in industrial and civil building ventilation and air conditioning projects. They are a type of municipal infrastructure used to circulate air and reduce the concentration of harmful gases. Ventilation pipes are generally classified by shape: circular, rectangular, serpentine, etc. The main components include straight pipes, bends, Tianyuandi (local Tianyuan), etc. Tianyuandi is a pipe fitting with a round top and a square bottom. It is a main component widely used in rectangular and circular ventilation ducts in ventilation and air supply systems. Its production is generally divided into eight parts, namely four arc-shaped plates and four triangular plates, and then manufactured by bending with a press and splicing. However, in large-section waste heat recovery ventilation ducts, due to the large volume of the pipe materials, deformation problems are likely to occur during welding, which can lead to problems in the later assembly and welding of the pipe fittings. Deformation problems are easy to occur. Therefore, how to effectively, simply, and quickly manufacture large-diameter, circular, and local pipe fittings is a technical problem that urgently needs to be solved.
