The invention relates to a high-temperature liquid pressure correcting and measuring device. A hollow bolt pipe connector (1) is connected with an external high-temperature gas source pipeline in a butt joint mode and connected with a high-temperature gas pipe inlet end (2). A pressure constant-temperature cavity (3) is arranged outside a high-temperature gas pipe in a surrounding mode. A cooling medium outlet pipeline (4) and a cooling medium inlet pipeline (6) are arranged on the pressure constant-temperature cavity (3) and connected with the pressure constant-temperature cavity (3). A low-temperature gas pipe outlet end (5) is connected with a temperature measuring device and a pressure measuring device. Pressure of high-temperature liquid is accurately and reliably measured, thermal load impact which is caused by high-temperature liquid to a test sensor is avoided, and the service life of the high-temperature pressure sensor is prolonged.
Description
technical field [0001] The invention belongs to the technical field of high-temperature fluid pressure testing systems, and in particular relates to a high-temperature fluid pressure correction testing device. Background technique [0002] The development of modern science and technology requires the accuracy of data measurement. In the process of scientific research, testing, etc., it is even more necessary to accurately measure the data of the researched system. Among them, pressure data is the most widely used state parameter in engineering. The accuracy of its measured value Directly affect the accuracy of scientific research and experiments. In the process of measuring high-temperature fluid, due to its inherent characteristics such as high temperature and high fluidity, the microscopic molecular kinetic energy and potential energy inside the high-temperature fluid change drastically, which causes the uneven change of its internal pressure field. At the same time, in t...
