The machining method is simple in step, manufacturing is easy and convenient, the using effect is good, and the air pipe joint machining process can be easily, conveniently and rapidly finished.

Description

Technical field [0001] The invention belongs to the technical field of construction of ventilation and air-conditioning systems, and in particular relates to a pressure-resistant air pipe anti-leakage structure of a ventilation and air-conditioning system and a method for processing air pipe sections. Background technique [0002] The ventilation and air-conditioning system is composed of a ventilation system and an air-conditioning system. The ventilation system is composed of blower, air duct, air duct components, muffler, etc.; while the air-conditioning system is composed of air conditioning cold and heat sources, air handlers, and air delivery pipes for transportation and distribution. And the air conditioner automatically controls and regulates indoor temperature, humidity, air velocity and cleanliness. Today, the energy consumption of ventilation and air conditioning systems due to air leakage is undoubtedly a major part of building energy consumption. In the ventilation ...

Problems solved by technology

[0005] Through the preliminary theoretical discussion and the quality tracking and scientific and technological novelty search of the whole process of metal air duct processing, assembly and installation, it is found that there are still some problems in the control of air leakage in the ventilation and air conditioning system, which are mainly manifested in the following five aspects: first, Existing research is unclear about the main areas of air leakage in the system; second, the impact of quality defects in each link of metal air duct production on air leakage in the system is unclear; third, there is a lack of thorough understanding of the air leakage mechanism of key parts Theoretical analysis; fourth, there is no innovation of the core key technology to reduce the air leakage of the system, only passive actions such as plugging are adopted, and there is no active action to actively adapt to the characteristics of the medium and the actual situation; fifth, more research has been done on the detection of air leakage devices in the system , but very little research on airtight principles and putting them into practice
