Pressure resisting type air pipe air leakage preventing structure of ventilation air conditioner system and air pipe joint machining method

Abstract

The invention discloses a pressure resisting type air pipe air leakage preventing structure of a ventilation air conditioner system. The pressure resisting type air pipe air leakage preventing structure comprises a pressure resisting type sealing structure and a clamping structure. The pressure resisting type sealing structure comprises a pressure resisting type sealing strip located between two flange edges of an air pipe flange. The clamping structure comprises a clamping piece clamped on the two flange edges. The pressure resisting type sealing strip is a T-shaped sealing strip. The T-shaped sealing strip comprises a clamping strip and a limiting strip located at the bottom of the clamping strip. The pressure resisting type air pipe air leakage preventing structure is simple, reasonable in design, convenient to install, good in using effect and capable of effectively reducing the air leakage amount of an air pipe of the ventilation air conditioner system. Meanwhile, the invention discloses an air pipe joint machining method. The method comprises the first step of metal panel cutting, the second step of seaming machining, the third step of flange machining edge machining, the fourth step of pipe joint body panel bending and the fifth step of seaming joint closing and compacting. 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 ...
