The German standard DC corrugated carbon steel globe valve is a specially designed valve, which combines bellows sealing and DC type construction to provide high sealing performance and prevent valve stem leakage. This valve is suitable for flammable, explosive, highly toxic, toxic fluids, high-temperature heat transfer oil, liquid ammonia and other media with nominal pressure PN16 and working temperature range from -29°C to 3425°C. They are widely used in petrochemical, chemical fiber textile, plastic papermaking, electric power, steel, printing and dyeing, rubber, natural gas and other industrial fields.
The structural features of the German standard DC corrugated carbon steel globe valve include:
1. The product has reasonable structure and reliable sealing, and adopts double sturdy and durable bellows sealing design (bellows + packing) to ensure zero leakage of valve stems, improve the safety of factory equipment, and comply with international sealing standards.
2. The sealing surface is surfacing Co-based cemented carbide, which has wear-resistant, corrosion-resistant, anti-friction properties and long service life.
3. The valve stem has been quenched and tempered and nitrided on the surface, which has good anti-corrosion and anti-friction properties; Stem lift position indication for more intuitive indication.
The selection principles for this type of valve include:
1. Globe valves should be selected on the pipelines or devices of high-temperature and high-pressure mediums, such as high-temperature and high-pressure pipelines in thermal power plants, nuclear power plants, and petrochemical systems.
2. Pipelines with lax requirements for convection resistance, that is, where pressure loss is not considered much.
3. There is flow adjustment or pressure adjustment, but the adjustment accuracy is not high, and the diameter of the pipeline is relatively small, such as the nominal passage ≤ 50mm pipeline, it is advisable to choose.
Attention should be paid to the installation and maintenance of German standard DC type corrugated carbon steel globe valve:
1. Hand wheel, handle operated globe valve can be installed in any position of the pipeline.
2. Hand wheels, handles and transmission mechanisms are not allowed to be used for lifting.
3. The flow direction of the medium should be consistent with the direction of the arrow shown on the valve body.
These valves are designed and manufactured to DIN standards, which often follow DIN standards, ensuring their quality and performance.
