Abstract
Abstract A huge control valve has a valve body comprising a block of castable material, such as concrete, and a plurality of pipes imbedded in the block. The pipes extend through the block from end to end. At one end of the block, the pipes are open. At the other end of the block, the pipes are connected to individually actuatable, preferably bistable, valve elements located external to the block. A diverging adapter conduit connects an upstream line conduit to the end of the block where the valve elements are located, and a diverging adapter conduit connects a downstream line conduit to the other end of the block. Preferably, the valve elements are spaced different distances from the block and are controlled by actuators external to the adapter conduits, which are each attached to a mounting frame anchored to the block. The valve body is constructed by fabricating a form, placing the pipes in the form in the desired arrangement, pouring the castable material into the form to produce a casting, and removing the form after the casting has hardened. In a specific application, the control valve is connected in a closed loop with a wind tunnel and a blower to produce shock waves in the wind tunnel.
