HIGH PRESSURE BOTTLE ADAPTER Russian patent published in 2019 - IPC B67B6/00 

FIELD: physics.

SUBSTANCE: on adapter housing with internal thread and sealing surfaces for consumer there installed is nut fixedly in axial direction and movable in circumferential due to balls located in annular hemispherical grooves of adapter housing and nut. On the sealing surfaces of the adapter housing, when it is attached to the neck of the cylinder, there is an annular groove for a rubber ring of round cross-section, as well as a cylindrical surface for a fluoroplastic ring of rectangular section contacting directly with aggressive medium contained in the balloon. Threaded surface of nut contacts with external thread surface of neck of cylinder, and sealing surface on adapter body contacts with inner sealed surface of neck. Balls from falling out of hemispherical grooves are fixed with locking screw, on surface of adapter housing and nut there is a zinc coating, diameter of balls 5…8 mm. On external surfaces of nut and housing of adapter there are polyhedral surfaces with number of flat faces of not less than two.

EFFECT: adapter can be used to equip high-pressure cylinders used in fire-extinguishing modules with various connection dimensions of shut-off and start devices and high consumption of media in cylinders.
