Butterfly Valve (Standard double flapper type; Flap damper)

Double flap dampers, also known as twin flap dampers, are specialized control devices used in transfer systems to moderate the flow of powders and granular materials. These dampers are made up of two flaps that can be adjusted to control the powder flow volume and direction.

Working Process of Double Flap Dampers

Double flap dampers are designed to maintain a smooth flow of materials, preventing clogging and ensuring efficient material transfer. The structure of a double flap damper includes several key components, such as the casing, chute, valve plate, shaft, bearing box, gland packing, bearing unit, and an inspection point. Each of these components plays a specific role in ensuring the proper functioning of the damper.

A double flap damper operates by using two flaps that open and close one after the other. Initially, the first flap opens to allow material passage, then closes. Following that, the second flap opens to maintain the material transfer and subsequently closes. This sequential flap movement regulates material flow, preventing blockages or disruptions in the transfer process.

Importance of Double Flap Dampers

Double flap dampers are essential for maintaining exact control over powder movement, minimizing unwanted surges or blocks that could affect production. These dampers are essential components of industrial process control systems, ensuring that powders are delivered consistently and efficiently to the desired destination.
