PRESSURE RELIEF VALVE FOR CONTAINERS ADAPTED FOR PNEUMATIC LOADING OF LOOSE SOLID PRODUCTS, IN PARTICULAR IN STORAGE HOPPERS Russian patent published in 2017 - IPC B65G53/12 B65G53/54 B65G53/60 F16K17/164 

FIELD: transportation.

SUBSTANCE: pressure relief valve for containers adapted for pneumatic loading of loose solid products, in particular in storage hoppers, comprises a valve body having a first end that pneumatically communicates with the outer part of the container and a second end that is connected to a flow control element that is exposed to the corresponding closing membrane. The flow control device periodically interacts via fluid with said valve body and a channel that communicates with the outer part. According to the invention, at least one portion of the channel that communicates with the outer part is adapted so as to be resiliently deformed by a pressure difference existing between the inner part of said container and the inner part of the channel.

EFFECT: low cost of the valve, facilitating its maintenance and preventing the release of the polluting air.
