Purkuventtiilit

Purkuventtiilit, often translated as relief valves or discharge valves, are safety devices designed to protect pressurized systems from over-pressurization. They function by automatically opening and releasing excess pressure when it exceeds a predetermined setpoint. This prevents damage to equipment, pipelines, and potential hazards to personnel.

The basic principle of operation involves a spring-loaded mechanism. When the pressure inside the system reaches the setpoint, it overcomes the force exerted by the spring, causing the valve to open. This allows the fluid (liquid or gas) to escape, reducing the internal pressure. Once the pressure drops below the setpoint, the spring force reasserts itself, closing the valve and resealing the system.

Purkuventtiilit are critical components in a wide range of applications, including boilers, pressure vessels, hydraulic systems, and pneumatic systems. They are essential for maintaining safe operating conditions and preventing catastrophic failures. The selection of a purkuventtiili depends on factors such as the type of fluid, operating pressure, temperature, flow rate, and the required level of protection. Regular maintenance and testing are crucial to ensure their reliable operation.
