Principle of toilet ventilation pipeline

Ventilation pipe is a metal or nonmetal pipe used in ventilation and air conditioning engineering of industrial and civil buildings, and it is a municipal infrastructure to make air circulate and reduce the concentration of harmful gases. [1] The main finished products such as plates and profiles used in the manufacture and installation of air ducts shall conform to the current national design standards and the provisions of related products, and shall apply for the factory inspection certificate. When materials enter the site, they shall be accepted according to the current national standards. Understand the principle of bathroom ventilation pipe with Bian Xiao.

Ventilation pipe is a kind of municipal infrastructure to make air circulate and reduce the concentration of harmful gases. The main finished materials such as plates and profiles used in the manufacture and installation of ventilation pipes and air ducts shall conform to the current national design standards and the provisions of related products, and pass the ex-factory inspection. When materials enter the site, they shall be accepted according to the current national standards. According to the material, ventilation pipes generally include: steel plate ventilation pipe (ordinary steel plate), galvanized steel plate ventilation pipe (white iron), stainless steel ventilation pipe, glass fiber reinforced plastic ventilation pipe, plastic ventilation pipe, composite material ventilation pipe, color steel sandwich insulation board ventilation pipe, double-sided aluminum foil insulation ventilation pipe, single-sided color steel insulation ventilation pipe, rubber-coated ventilation pipe (such as mine ventilation pipe), mining plastic ventilation pipe, etc.

Air ducts are mainly used in industrial and construction projects, and their application fields mainly involve: clean systems in clean workshops of electronics industry, clean systems in sterile workshops of medicines and foods, central air conditioning systems in hotels, shopping malls, hospitals, factories and office buildings, exhaust pipes for dust removal, smoke extraction and oil absorption in industrial pollution control, air supply pipes for comfortable industrial environment or jobs, gas drainage systems for gas drainage in coal mines, return air systems for environmental control in coal mines, etc. PS: It is often developed into a special escape and stealth route in movies and comics.

The material grade varies according to the use.

1. air duct for air conditioning system: galvanized sheet and stainless steel; (It is forbidden to use glass fiber reinforced plastics and composite materials that may cause dust pollution)

2. Air duct of central air conditioning system: galvanized sheet and color steel insulation board; (Ventilation pipes can be made of FRP and composite materials)

3. Air duct of environmental control system: galvanized sheet and stainless steel; (Plastic, FRP and composite materials can be used)

4. Air ducts for industrial ventilation systems: steel plates and galvanized plates; (Ladbrokes ventilation duct. Plastic, glass fiber reinforced plastic and composite materials can be used) Note: Glass fiber reinforced plastic air ducts are divided into organic and inorganic types, and the use of organic materials is prohibited according to the design specifications;

5. Air ducts for special use occasions: mine coated air ducts and mine plastic ventilation air ducts; (Mine safety features requiring flame retardancy and antistatic property)

Finally, it is worth mentioning that no matter how well the bathroom is ventilated, we should pay attention to what to do if the bathroom is not well ventilated. Bian Xiao believes that in order to effectively prevent accidents caused by poor ventilation in the bathroom, it is necessary to have a little knowledge of bathroom safety and install ventilators, so that any potential safety hazards in the bathroom can be dealt with in time. Therefore, tragic accidents can be avoided.
