varoventtiilit

Varoventtiilit are safety devices designed to protect pressurized systems from overpressure. Their primary function is to automatically release excess pressure by opening a valve and discharging a fluid or gas when a set pressure limit is reached. Once the pressure drops to a safe level, the valve closes.

These devices are crucial in a wide range of applications, including boilers, pressure vessels, pipelines, and refrigeration systems. They act as a last line of defense, preventing catastrophic failures that could result from excessive pressure buildup. The design of a varoventtiili typically involves a spring-loaded disc or piston that is held against a valve seat. When the system pressure exceeds the spring force, the disc or piston is pushed open, allowing the overpressure to escape.

The set pressure, or the pressure at which the varoventtiili activates, is a critical parameter and is carefully determined based on the design limits of the system it protects. Regular inspection and testing of varoventtiilit are essential to ensure their reliable operation. Failure of a varoventtiili can have severe consequences, including equipment damage, injury, or even fatalities. Therefore, their proper functioning is a paramount concern in industrial safety.
