バルブは媒体の流れと圧力を制御するための重要な制御機能を備えた重要な部品です。. In power engineering, valves are widely used in various fluid pipelines to control flow, adjust pressure and prevent backflow. The special requirements of power engineering such as pressure, 温度, density and medium also make valves more demanding.
Main applications in the power industry
In the power industry, valves are widely used, mainly including electric regulating valves and special valves for power stations. The application of valves in the power industry covers many aspects from boiler control to flue gas emission control, ensuring the safety, stable operation and energy efficiency optimization of power equipment.
1.Electric regulating valve
- Boiler control: used for water level control, pressure control, temperature control, 等. in the boiler system. By adjusting the valve opening, the fuel supply, water flow and other parameters are controlled to ensure the stable operation and efficiency optimization of the boiler.
- Generator control: used for the flow control of cooling water, lubricating oil and other media in the generator set. By adjusting the valve opening, the normal operating temperature and lubrication state of the generator are maintained.
- Steam control: used for flow, temperature and pressure control in steam systems, and the valve opening is adjusted to ensure stable operation and energy regulation of steam systems.
- Flue gas emission control: used in flue gas emission systems of power plants to adjust the flow and temperature of flue gas to meet environmental protection requirements.
- Energy recovery: used in energy recovery systems in the power industry, and the flow and temperature of recovered fluids are controlled by adjusting the valve opening to achieve energy recovery and reuse.
2.Power station special valves
としても知られている power station valves, are mainly used in pipelines of various systems in thermal power plants to cut off or connect pipeline media. These valves are suitable for non-corrosive media such as water and steam, and have the characteristics of high temperature and high pressure. The unique self-sealing design makes it more reliable to seal under high pressure.
Common valves in power engineering
- Shut-off valve The shut-off valve is a common valve that can be used to cut off or open the flow of media in the pipeline. In power engineering, shut-off valves are usually used to open and close pipelines and regulate flow.
- Regulating valve
The regulating valve can adjust the medium flow or pressure in the pipeline according to the working conditions. In power engineering, regulating valves are mainly used to control and regulate fluids to ensure the smooth and safe operation of equipment. - 逆止め弁
The check valve is mainly used to prevent the backflow and reflux of the medium and ensure the one-way flow of the fluid in the pipeline. In power engineering, check valves are often used to protect equipment to avoid damage to the equipment after the medium stops flowing. - バタフライバルブ
The butterfly valve is a valve with a simple structure and light weight, which is mainly used for the opening and closing of pipelines and flow regulation. In power engineering, butterfly valves are often used to accurately control the flow to meet the requirements of equipment operation.
要約すれば, The application of valves in power engineering is very extensive, involving many aspects such as fluid control, pressure regulation and equipment protection. With the development of power engineering, the types and complexity of valves are becoming more and more diverse, and the requirements for valve performance are becoming higher and higher. したがって, mastering the types, structures and characteristics of valves is very important for the actual operation of power engineering.
