sulgventiili

Sulgventiili, also known as a shut-off valve or isolation valve, is a mechanical device used to control the flow of a fluid within a system. Its primary function is to either completely stop or allow the passage of the fluid. Unlike control valves that modulate flow, sulgventiili are designed for on-off operation. They are commonly found in plumbing, industrial pipelines, and various mechanical systems where the ability to isolate sections for maintenance, repair, or emergency shutdown is crucial.

The operation of a sulgventiili typically involves a movable component that obstructs or opens the flow path. Common types include gate valves, where a disc or wedge is lowered or raised, and ball valves, which use a spherical plug with a bore that aligns with the pipe when open and is rotated perpendicular to the flow when closed. Other variations exist, such as butterfly valves and plug valves, each with distinct mechanisms for flow control. The selection of a specific sulgventiili type depends on factors like the fluid type, pressure, temperature, and required sealing performance. Proper installation and maintenance are essential to ensure the reliable operation of sulgventiili and prevent leaks.
