GATE FOR VESSEL CONTAINING FLUID PRODUCT Russian patent published in 2009 - IPC B65D47/08 B65D47/20 

FIELD: transportation; packing.

SUBSTANCE: gate for vessel containing fluid product contains immobile bottom part and mobile top part. Additionally immobile bottom part is implemented with ability of sealed fixation of throat of vessel and allows overlap with projecting adapter, and mobile top part is implemented with ability of co-axial movement on bottom part between external position and internal position. Gate also contains allowing shape of bowl diaphragm valve made of flexible for curvature material, top edge of which adjoin with sealing to bottom side of top part. Additionally diaphragm valve allows openings in its bottom, which are closed in position of rest of top part. Additionally diaphragm valve permanently spring-load top part in the direction of its external position. Additionally diametre of bottom of diaphragm valve is higher internal diametre of adapter and external end of adapter permanently supports bottom of diaphragm valve so that ensured by axial pressure on top part in the direction of vessel bottom of diaphragm valve incurvates outwards and there are opened openings of bottom.

EFFECT: strict delivery of fluid facilities at simplicity of structure.
