Ventuurventiilid

Ventuurventiilid, also known as venturi valves, are specialized control valves designed to regulate flow based on the venturi effect. The venturi effect describes the reduction in fluid pressure that results when a fluid flows through a constricted section of a pipe. In a venturi valve, this constriction is intentionally incorporated into the valve's design, often as a narrowed throat.

When a fluid passes through this constricted throat, its velocity increases, and according to Bernoulli's principle, its pressure decreases. This pressure drop is directly related to the flow rate. Venturi valves utilize this principle to modulate flow by adjusting the size of the throat or by controlling the pressure differential across it. This allows for precise control over the volume of fluid or gas being passed through the system.

These valves are particularly useful in applications where accurate flow measurement or control is critical. They can be found in various industries, including water treatment, chemical processing, and pneumatic systems. The inherent design of a venturi valve often leads to lower pressure loss compared to traditional throttling valves, which can improve energy efficiency in some systems. Their robust construction and ability to handle abrasive fluids also make them suitable for demanding environments. The operation relies on the physical properties of fluid dynamics rather than complex mechanical actuation, contributing to their reliability.
