Ball valves, butterfly valves, gate valves and globe valves produced by Tianjin Valve Factory are common valve types, which play a key control role in the industrial production process. This article will analyze the characteristics and application scenarios of these valves, and provide guidance for readers to choose the right valve.
1. Ball Valve
Ball valve is a kind of valve that controls the medium by rotating the ball. It has the following characteristics and applicable scenarios:
Features:
1. Quick switch: the operating rod of the ball valve can be fully opened or fully closed only by rotating 90 degrees, and the operation is fast and convenient.
2. Small resistance: the diameter of the fluid channel of the ball valve is relatively large and the diameter of the pipeline, and the fluid resistance in the valve is small.
3. Good sealing: The ball valve is made of elastic material sealing ring, with good sealing performance.
Application scenario:
1. High pressure pipeline: Ball valve can withstand high pressure, suitable for high pressure pipeline switch control.
2. Fluid control: Ball valve can be used for liquid, gas and other media control.
3. Quick cut-off: The quick switching characteristics of the ball valve make it suitable for situations where fluid flow needs to be stopped quickly.
Two, Butterfly Valve (Butterfly Valve)
Butterfly valve is a disc rotation to control the medium flow valve. It has the following characteristics and applicable scenarios:
Features:
1. Simple structure: butterfly valve has simple structure, small size and easy installation.
2. Quick switch: the butterfly valve operating rod can be fully opened or fully closed by rotating only 90 degrees, and the switch is fast.
3. Small fluid resistance: When the disc of the butterfly valve is fully open, the resistance of the medium is small.
Application scenario:
1. Large flow pipe: Butterfly valve is suitable for occasions requiring large flow control, such as industrial pipes, water supply and drainage systems.
2. Low pressure pipeline: butterfly valve can withstand lower pressure, suitable for low pressure pipeline flow control.
3. Clean medium: Butterfly valve is suitable for clean liquid or gas medium, not suitable for occasions containing granular matter or high viscosity medium.
Three, Gate Valve (Gate Valve)
Gate valve is a valve that controls the medium by lifting the gate plate. It has the following characteristics and applicable scenarios:
Features:
1. Good sealing: gate valve adopts plane sealing or lifting sealing structure, with good sealing performance.
2. High resistance: When the gate valve is fully open, the resistance of the fluid through the valve is large, but in the fully closed state, the resistance is small.
3. Full open and full close: the gate valve operating rod needs to be rotated several times to achieve full open or full close state.
Application scenario:
1. Cut off fluid: Gate valves are suitable for situations where the fluid flow needs to be completely cut off.
2. High pressure pipeline: gate valve can withstand high pressure, suitable for the control of high pressure pipeline.
3. Normally open, normally closed state: gate valves are often used in systems that need to remain normally open or normally closed, such as fire water systems, cooling water systems, etc.
Four, Globe Valve (Globe Valve)
The globe valve is a valve that controls the on-off of the medium and regulates the flow rate by moving the spool up and down. It has the following characteristics and applicable scenarios:
Features:
1. Flow regulation: The globe valve can adjust the fluid flow by adjusting the rise and fall of the spool.
2. Good sealing: The globe valve adopts the lift sealing structure and has good sealing performance.
3. Large resistance: Due to the existence of the spool, the resistance of the stop valve is relatively large.
Application scenario:
1. Flow regulation: The globe valve is suitable for occasions where the fluid needs to be accurately adjusted, such as heating and cooling systems.
2. Small and medium diameter pipeline: the globe valve is suitable for small and medium diameter pipeline system.
3. Normally open, normally closed state: The globe valve is often used in systems that need to remain normally open or normally closed, such as water supply pipeline systems.
When choosing the valve produced by Tianjin Valve manufacturer, it is necessary to determine which valve type is most suitable for use according to the actual industrial scenarios and needs. Ball valve is suitable for high pressure pipelines and fast cut off fluid occasions; Butterfly valves are suitable for large flow and low pressure pipelines, but there are certain restrictions on particulate matter and high viscosity media; Gate valves are suitable for cutting fluid and high pressure pipelines, often used in normally open or normally closed systems; The globe valve is suitable for flow regulation and small and medium diameter pipelines, and is also commonly used in normally open or normally closed systems.
Through the analysis of these valves, we hope to help readers make accurate judgments when choosing the right valve type, and provide better control and safety guarantee for industrial production.
