EMERGENCY DISCONNECTION DRIVE COUPLING Russian patent published in 2022 - IPC F16L29/00 

FIELD: piping equipment.

SUBSTANCE: invention relates to a system of emergency shutdown and disconnection as part of standpipes, feeding, loading, reloading hoses, articulated pipelines and manipulators, in refueling installations. The emergency disconnection drive coupling contains two actuators, two sections with flanges and a clamp divided into two half-rings, where each section contains a rotary type locking device that has a rod and a mounting surface of the yoke assembly, and the flanges of the first and second sections closest to each other have a beveled edge to cover the half-rings of the clamp. The first half-ring has a housing, a bursting lock, at least two plates, at least one cable, a spring with a gasket, a tension cam with a hole and a rod that has a hole for the axle. The second half-ring has a housing, an axle, at least two plates, at least one cable, a spring with a gasket, a tension cam, an opening rod with a stop-cam at the end, and the bursting lock has a fork with a safety pin, and two actuators are placed on at least one mounting bracket fixed to the flanges and mounting surfaces the upper section. The first actuator includes: a drive, a tip with a hole for the roller, two parallel rods, at least one lock for spontaneous rotation of the locking device, at least two sensors and two rocker arms with a position indicator and a bearing support with grooves for the lock. The second actuator consists of the first and second stop-guides, at least one sensor, a drive connected to a disconnecting cam having at least one cone-shaped protrusion.

EFFECT: invention provides a guaranteed separation of pipelines with a preliminary hermetic overlap of its two sides.
