Abstract
The invention provides a double-channel flow test switching device. The double-channel flow test switching device comprises a base, air inflow pipes, pressing plates, an upper cover plate, a lower cover plate and a bottom plate. The base is a double-step barrel-shaped ring. The twenty or more air inflow pipes are arranged on the outer side of the base to be communicated with the interior of the base, and the air inflow pipes are evenly distributed along the circumference of the base; a part is placed in the base in a double-step spanning mode, the part is vertically covered with the upper cover plate and the lower cover plate in a pressed mode, and the upper cover plate and the lower cover plate are fixed through bolts. The upper cover plate and the lower cover plate are each in a disc shape, the circumference radius of the outer edge of the upper cover plate is larger than the internal diameter of the base, and the circumference radius of the outer edge of the lower cover plate is smaller than the internal diameter of the base. It is guaranteed that an air flow test conducted between a high-pressure turbine disc and a lower-pressure turbine disc is simple, light and convenient, assembly and disassembly are easy, and the switching device can be conveniently connected with equipment of a test bed. Flow measurement is accurate, and air flow is good. Gas flow in the detection process is easy to adjust through thread exhaust holes and screw plugs.
