Survetõkkeid

Survetõkkeid, often translated as pressure barriers or pressure relief devices, are engineering components designed to control or dissipate excess pressure within a system. Their primary function is to prevent damage to equipment, pipelines, or structures that could be caused by overpressurization.

These devices operate on various principles. Some act as vents, releasing pressure when it exceeds a predetermined threshold. Others might reroute excess pressure to a safer location or dampen pressure fluctuations. The design and specific mechanism of a survetõke depend heavily on the application, the type of fluid or gas being managed, and the expected pressure range.

Common types include relief valves, rupture discs, and surge suppressors. Relief valves are spring-loaded or pilot-operated devices that open at a set pressure and close when the pressure drops. Rupture discs are thin membranes designed to burst at a specific pressure, providing a one-time pressure relief. Surge suppressors, often filled with air or gas, absorb sudden pressure spikes or surges in liquid systems.

Survetõkkeid are crucial in a wide range of industries, including oil and gas, chemical processing, water supply, and power generation. They play a vital role in ensuring operational safety, preventing catastrophic failures, and maintaining the integrity of complex systems. Regular inspection and maintenance are essential to guarantee their reliable performance.
