QUICK-SPLIT UNIT Russian patent published in 2012 - IPC F16L37/40 

FIELD: machine building.

SUBSTANCE: within a composition of a ground pad a pneumatic pusher installed on a body of a pneumatic drive is arranged in the form of a piston. At the same time the minimum force of a pulling-off device and maximum push-away force from the pneumatic drive is not transferred to trusses of filling-draining masts. A quick-split unit comprises a board and a ground pads with filling nozzles, a collet lock, a pneumatic drive with a piston, a lock bushing, a reverse valve, a pull-away device. The pneumatic pusher is installed on the body of a pneumatic drive and is connected by its one end to the pull-away device of the pneumatic drive, and by its other end is connected with the mechanism to divert a filling truss and is arranged in the form of a piston with a control cavity, and piston stroke exceeds the value of collet joint opening. In the pneumatic drive the pull-away device and stroke limiter are arranged with a stroke, the value of which exceeds the value of lock joint opening.

EFFECT: invention provides for reliable separation of board and ground nozzles, also in case of emergencies.
