Abstract

The invention discloses an internal flow path detecting tool for a turbine guide vane. The internal flow path detecting tool comprises a water inlet pipe, a pressure stabilizing connecting block, a curved surface sealing plate and a pressing plate. One end of the water inlet pipe is provided with a pressure stabilizing cavity, and the end is connected to a port of a water flow channel inside the voltage stabilizing connection block through a locking nut. The pressure stabilizing connecting block presses against the back side of the curved surface sealing plate, the curved surface sealing plateis provided with a flow groove which passes through the back side and the inner side of the curved surface sealing plate, the flow groove communicates with the water flow channel in the pressure stabilizing connecting block, the pressing plate is arranged at one side close to the inner side of the curved surface sealing plate, a detected turbine guide vane is arranged between the pressing plate and the curved surface sealing plate, a sealing plate of one end of two ends of the detected turbine guide vane fits the curved surface sealing plate, and a sealing plate of the other end fits the pressing plate. The structure of the internal flow path detecting tool is simple and novel, the flow capacity of the internal flow channel of the turbine guide vane can be continuously and stably detectedthrough the overall structural design.

Description

technical field [0001] The invention relates to the field of fixtures, in particular to a tool for detecting the internal flow path of a turbine guide vane. Background technique [0002] In order to obtain the water flow rate of the internal cooling channel of the guide vane of the low-pressure turbine of an engine under the specified pressure, the processing of the internal flow channel of the blade is inspected to judge whether the flow capacity of the blade meets the requirements. The surface to be sealed in the test is the upper and lower rafters of the blade, both of which are rough surfaces and are curved surfaces, so it is difficult to form an effective seal, thereby reducing the test effect and unable to obtain stable water flow data. Contents of the invention [0003] The object of the present invention is to provide a tool for detecting the internal flow passage of a turbine guide vane, so as to solve the problems raised in the above-mentioned background technolo...
