Turvaventtiilejä

Turvaventtiili, often referred to as a relief valve or safety valve, is a type of valve that protects a pressure vessel or system from becoming over-pressurized. It is designed to open automatically at a predetermined set pressure to allow the discharge of fluid (liquid or gas). This discharge relieves the excess pressure, preventing catastrophic failure of the equipment or pipeline. The valve then closes once the system pressure has returned to a safe level.

The operation of a turvaventtiili is typically based on a spring-loaded mechanism or a pilot-operated system. In a spring-loaded valve, a spring holds the valve disc closed against a seat. As pressure increases, it exerts a force on the disc that opposes the spring force. When the system pressure reaches the set point, the force on the disc overcomes the spring force, causing the valve to open. Pilot-operated valves use a smaller pilot valve to control the main valve, which can offer greater accuracy and reliability in certain applications.

Turvaventtiilejä are critical safety components in a wide range of industries, including chemical processing, oil and gas, power generation, and HVAC systems. They are installed on boilers, pressure tanks, pipelines, and other equipment where over-pressurization is a risk. Regular inspection and testing of turvaventtiilejä are essential to ensure their proper functioning and to maintain the safety of the system. Failure of a turvaventtiili can lead to equipment damage, environmental hazards, and severe injury or even death.
