Pivotal hopper tee with alignable swing-away hopper tee assembly

A swing-away hopper tee assembly for attachment to a discharge opening in a hopper comprising:

• a mounting frame assembly for attachment at the discharge opening of the hopper;
• a valve housing assembly below the mounting frame, the valve housing assembly removably receiving a flow control valve;
• a hopper tee positioned below the valve housing assembly and having an opening through which material can flow from the flow control valve, the hopper tee being pivotally attached to the mounting frame assembly for movement between a first closed position in which said hopper tee opening is in fluid communication with said flow control valve and a second opened position in which said hopper tee is out of alignment with said flow control valve to expose said flow control valve to enable the flow control valve to be removed from the valve assembly housing;
• a first alignment member on said hopper tee and a second alignment member on one of said mounting frame and valve housing assembly, said first and second alignment members cooperating with each other to align the hopper tee opening with the flow control valve;
• a camming means and engagement assembly for releasably securing the hopper tee to the mounting frame;
• the camming means and engagement assembly including:
• a locking member movable between an unlocked position in which said hopper tee can be pivoted away from its first to its second position to expose said flow control valve and a locked position to secure said hopper tee in said first position;
• and
• a cam for securing the locking member in the locked position.
