Abstract
A coupling for conduits through which passes a liquid that must be kept from spilling and/or from being exposed to the air, comprises a pair of parallelepipedal blocks in each of which is disposed a ball valve. Two flat faces of the blocks mate, whereupon the blocks are releasably secured together by bolts. The ball valves are disposed as close as possible to the mating interface of the blocks; and the liquid passageway that opens through the mating faces is surrounded by an annular bevel. Each ball valve has an operator whose rotation through 90.degree. between open and closed valve positions is predetermined by a pin on the operator that engages one or the other face of a recess milled in the block. A pin disposed in a hole in the block is disposed in an annular groove in the valve operator to retain the operator in the block.
