What are the advantages and applications of globe valves
Globe valve is a widely used type of valve, mainly used to cut off or regulate the flow of medium in pipelines. The characteristic of a globe valve is that its opening and closing member is a plug shaped valve disc, with a flat or conical sealing surface, and the valve disc moves linearly along the centerline of the valve seat.
Advantages of globe valves:
1. Good sealing performance: When the cast steel globe valve is closed, the valve disc and seat can be tightly fitted, providing effective sealing effect.
2. Easy to operate: The manual shut-off valve can be easily opened or closed by rotating the handle, while the automatic shut-off valve can be controlled by electromagnetic or pneumatic drive.
3. Wide applicability: Stop valve is suitable for flow control of various liquids and gases, including flammable gases, steam, petroleum, chemical, pharmaceutical and other fields.
4. Strong resistance to high temperature and corrosion: Modern water globe valve use special materials such as high-temperature alloys and stainless steel to adapt to harsh working environments.
Disadvantages of globe valves:
1. High fluid resistance: The internal flow channel of the 6 Inch globe valve is relatively tortuous, resulting in high fluid resistance when passing through the valve, which may cause energy waste.
2. Large opening and closing torque: Globe valves require a large torque to open and close, especially under high pressure or large diameter conditions.
3. Not suitable for certain specific media: Motorized globe valve are not suitable for media with particles, high viscosity, or easy coking, as these media may affect the normal operation and sealing performance of the valve.
4. Poor regulating performance: Although globe valve price can be used to regulate flow, their regulating performance is not as good as specially designed regulating valves.
Globe valves are widely used in various industrial pipeline systems, such as petrochemicals, metallurgy, power, pharmaceuticals, etc., due to their simple structure and good sealing performance. They are usually used to cut off or regulate the flow of fluids, ensuring the safe and stable operation of pipeline systems. In urban construction, water supply and heating projects, as well as building and municipal areas such as water supply and drainage systems and HVAC systems, are also widely used. In addition, shut-off valves are also used in fluid control experiments and instrument equipment in laboratories and research institutions.
