Check valve is an important fluid control equipment, its application range is wide, suitable for a variety of fluid media. The following is a detailed summary of the fluid medium applicable to the check valve:
First, common fluid media
1. Liquid medium
Water: Check valves are widely used in water supply and drainage systems to prevent sewage or water backflow.
Oil: including lubricating oil, hydraulic oil, etc., the check valve can prevent the backflow of oil media and protect the equipment from damage.
Acid lye: In the chemical industry, check valves can be used to discharge acid and alkali corrosive media.
Other liquids: such as acid, lye and other liquid media with special properties, the check valve is also suitable, but it is necessary to choose the appropriate material and structure according to the characteristics of the medium.
2. Gas medium
Air: The check valve prevents air backflow in the air compression system.
Nitrogen, oxygen and other industrial gases: in steel, metallurgy, petrochemical and other industries, check valves are used to prevent industrial gas backflow.
Gas: such as gas, natural gas, etc., the check valve is installed at the end of the gas pipeline to prevent gas backflow and ensure the safety of users.
3. Steam medium
Low temperature, medium temperature, high temperature steam: The check valve plays a role in the steam system to prevent steam backflow and water hammer, protecting the equipment from damage.
Second, special fluid medium
Sewage and wastewater: In sewage treatment and wastewater discharge systems, check valves are used to prevent sewage and wastewater backflow and protect the environment and equipment.
Seawater: Check valves can be used in seawater discharge systems to withstand corrosion and erosion of seawater.
Grease and medium strength chemicals: In specific industrial situations, the check valve can be used to discharge grease and medium strength chemicals and other media.
Third, field of application
The application areas of check valves cover almost all areas where it is necessary to prevent media backflow, including but not limited to:
Household life: such as water supply and drainage system, water heater outlet, dishwasher and washing machine and other household appliances.
Industrial production: such as chemical, petroleum, metallurgy and other industries in the pipeline system.
Hvac systems: such as hot water supply piping and heating systems.
Gas system: such as gas or natural gas pipe end.
New energy fields: such as solar hot water systems, wind power systems, etc.
Environmental protection: such as sewage treatment, waste incineration and other environmental protection projects.
In summary, the check valve is suitable for a variety of fluid media, including common liquid, gas and steam media, as well as special sewage, wastewater, seawater, grease and medium strength chemicals and other media. When selecting the check valve, the appropriate material, structure and model should be selected according to the characteristics of the medium, working pressure, temperature and other conditions.
