Kuljetinventtiilit

Kuljetinventtiilit, often translated as transport valves or flow control valves in English, are mechanical devices used to regulate or control the flow of materials, most commonly bulk solids, in industrial processes. These valves are essential components in systems where materials need to be precisely metered, diverted, or shut off from a continuous stream.

The primary function of a kuljetinventtiili is to manage the movement of powdery, granular, or lumpy substances. They achieve this through various mechanical actions, such as opening, closing, or partially obstructing a passage. The design and specific operation depend heavily on the type of material being handled, the required flow rate, and the pressure conditions within the system.

Common types of kuljetinventtiilit include slide gates, rotary valves (also known as rotary feeders or star feeders), butterfly valves, and diverter valves. Slide gates are often used for simple on-off control. Rotary valves are particularly effective for both feeding and controlling the flow of bulk solids in a sealed manner, preventing dust escape and maintaining pressure differentials. Butterfly valves, while also used for liquids, can be adapted for certain solid handling applications. Diverter valves are designed to direct the flow of material to different destinations.

The selection of a kuljetinventtiili is critical for efficient and safe operation. Factors such as material abrasiveness, particle size, bulk density, temperature, and the need for dust containment all influence the choice of valve type and materials of construction. Proper maintenance and operation of these valves are crucial to prevent blockages, wear, and potential system failures.
