Product Description
A Safety Valve is a critical device used to protect equipment, systems, and people from overpressure by automatically releasing fluid (gas or liquid) when pressure exceeds a preset limit. It is a fail-safe mechanism widely used in various industries.
Key Components
- Body: Houses the valve and fluid flow path.
- Spring: Applies force to keep the valve closed under normal pressure.
- Disc: The sealing element that prevents leakage.
- Nozzle: Directs the flow of fluid during operation.
- Adjusting Screw: Allows setting of the desired pressure release level.
Working Principle
- The valve remains closed under normal operating pressure due to the spring force.
- When the system pressure exceeds the preset limit, it overcomes the spring force and lifts the disc, allowing the excess pressure to escape.
- Once the pressure normalizes, the spring pushes the disc back to seal the valve.
Types of Safety Valves
- Spring-Loaded Safety Valve: Uses a spring mechanism for pressure regulation.
- Pilot-Operated Safety Valve: Uses an auxiliary pilot valve to control the main valve.
- Balanced Safety Valve: Includes bellows or diaphragms to mitigate backpressure effects.
- Thermal Safety Valve: Specifically designed to release pressure caused by thermal expansion.
Applications
- Oil and Gas: Prevents pressure buildup in pipelines and storage tanks.
- Boilers and Pressure Vessels: Protects against dangerous overpressure.
- Chemical and Petrochemical: Ensures safety in systems handling volatile or hazardous materials.
- Pharmaceuticals and Food Processing: Ensures compliance with safety and hygiene standards.
Key Benefits
- Prevents equipment failure or explosions due to overpressure.
- Ensures operational safety and compliance with safety regulations.
- Reduces downtime and maintenance costs by mitigating risks.
