Forged Steel Valves refer to valve devices that are suitable for cutting off or connecting pipeline media on pipelines of various systems in thermal power plants. There are many types of forged steel valves, which can be divided into the following main types according to their structures and functions:
Main types of Forged Steel Valves
Forged Steel Check valve
Used to automatically prevent gas or liquid backflow in pipelines.
Forged Steel Gate Valve
Controls the flow of media by lifting or lowering a gate plate, suitable for systems that need to be fully opened or closed. Forged steel gate valves often ignore pressure issues during operation, and attention should be paid to pressure control during grease injection operations.
Forged Steel Ball Valve
A rotary valve that controls the flow of media by rotating a sphere with holes. Double-seat sealed ball valves usually have bidirectional flow, and have the advantages of reliable sealing, light and flexible operation, small size, and light weight.
Forged Steel Globe Valve
Used to open or close the flow of pipeline media. Its structure is relatively simple, easy to manufacture and maintain, and suitable for medium and low pressure pipeline systems.
Pressure Sealed Bonnet gate valve, Pressure Sealed Bonnet Globe valve, Pressure Sealed Bonnet check valve
These valves adopt Pressure Sealed Bonnet design. The higher the pressure, the more reliable the seal. They are suitable for high-pressure pipeline systems.
Forged Steel Needle Valve
Usually used in occasions where precise flow adjustment is required. It has a simple structure and good sealing performance.
Forged Steel Insulation Valve
Specially designed for insulation system to reduce heat loss and improve energy efficiency.
Forged Steel Bellows Valve
Mainly used in occasions where bellows structure is required to achieve special functions, such as corrosion resistance, high temperature resistance, etc.
Other classification methods of Forged Steel Valves
In addition to the above main types, forged steel valves can also be classified according to other characteristics, such as:
- Classification by medium temperature: It can be divided into low-temperature forged steel valves, medium-temperature forged steel valves and high-temperature forged steel valves.
- Classification by drive mode: It can be divided into manual forged steel valves, electric forged steel valves, pneumatic forged steel valves, etc.
Forged Steel Valves Precautions
When using forged steel valves, you need to pay attention to the following points:
- Select the appropriate valve type: Select the appropriate valve type according to the pressure, temperature, medium characteristics and other factors of the pipeline system.
- Correct installation and maintenance: Correctly install and maintain the valve according to the valve instruction manual to ensure the normal operation of the valve and extend its service life.
- Pay attention to safe operation: When operating the valve, you need to pay attention to the safe operating procedures to avoid accidents.
In summary
There are many types of forged steel valves, and the selection needs to be comprehensively considered according to specific usage scenarios, functional requirements, safety standards and other factors. At the same time, during use, you need to pay attention to correct installation, maintenance and operation to ensure the normal operation of the valve and the safety and stability of the system.
