Pneumatic valves are widely used in industrial production, and there are many application cases.
First of all, there are many application cases of pneumatic valves in the oil industry. In the petrochemical production, due to the complex process conditions and strong corrosive medium, the valve is required to have the characteristics of corrosion resistance, wear resistance and good sealing. Pneumatic valves are widely used in various process segments in the petroleum industry because of their reliable sealing performance and fast operating response speed.
For example, in refining units, pneumatic ball valves are widely used in oil storage tank areas, oil loading and unloading areas and other important areas. The pneumatic butterfly valve is used in key positions such as the oil inlet and outlet pipelines and needle holders of kerosene storage tanks, which ensures production safety and improves operation efficiency.
At the same time, in the chemical industry, there are many application cases of pneumatic valves. For example, in ethylene production, the pneumatic control valve can realize the automatic control of ethylene steam destruction furnace, adjust the import and export flow, and ensure the stability and safety of production. Pneumatic valves are also widely used in the control system of distillation towers, reactors, separators and other devices in chemical processes to ensure the accurate control of process parameters and the convenience of operation.
In addition, pneumatic valves are also widely used in the power industry. In thermal power plants, pneumatic valves are used to control important equipment such as boiler feed water quality control system, reheat system and temperature reduction system. Through the accurate control of the pneumatic control valve, the stable operation of the boiler and the improvement of thermal efficiency can be achieved.
In the metallurgical industry, pneumatic valves also play an important role. For example, pneumatic control valves are widely used in the process of steel refining, which can accurately control the flow of cooling water and gas to achieve the stability of furnace temperature and the flow control of slag. Pneumatic knife gate valve and pneumatic globe valve are also widely used in blast furnace, converter and other important equipment import and export control, to ensure the normal operation of equipment and improve production efficiency.
In addition, in the water treatment industry, pneumatic valves are also widely used. For example, the pneumatic control valve is widely used in the sewage pumping room, pumping station and other important equipment in the water supply and drainage system. By controlling and adjusting the opening of the valve, the accurate control of water pressure, liquid level and other parameters can be achieved to ensure the stability of water supply and the safety of drainage.
In summary, the application cases of pneumatic valves in industrial production are rich and diverse, covering many industries such as petroleum, chemical, electric power, metallurgy, and water treatment. Through its reliable sealing performance and fast operating response speed, pneumatic valves provide important support and guarantee for the production process of various industries.
