Abstract

The invention relates to the field of valve test, and discloses an ultra-supercritical safety valve test platform under an actual working condition, and the test platform comprises an air inlet pipe; one end of the air inlet pipe is connected with a main steam pipeline of the 660MW ultra-supercritical generator set, and the other end of the air inlet pipe is connected with the test pipe section; a safety valve test tube seat is arranged in the middle of the test tube section, and a safety valve is arranged above the safety valve test tube seat; and an electric gate valve is arranged on the air inlet pipe. According to the invention, the problem that the ultra-supercritical safety valve cannot be subjected to a simulation test according to the actual working conditions, namely the design temperature of 605 DEG C and the design pressure of 25MPa, is solved. According to the invention, the testing capability of the ultra-supercritical safety valve can be improved, so that whether the performance of the ultra-supercritical safety valve meets the use requirement or not can be verified.

Description

technical field [0001] The invention belongs to the field of valve testing, and more specifically relates to an ultra-supercritical safety valve testing platform under actual working conditions. Background technique [0002] The existing safety valve test platform can only meet the test requirements of subcritical and below parameter unit safety valves, the test pressure is less than 20MPa, and the test steam temperature is less than 400°C. The design temperature of the ultra-supercritical safety valve is 605°C and the design pressure is 25MPa. The pressure and temperature parameters of the existing safety valve test platform cannot meet the actual parameters of the ultra-supercritical safety valve. Thermal action performance test requirements. Contents of the invention [0003] In order to solve the problem that the pressure and temperature parameters of the safety valve test platform in the prior art cannot meet the test requirements of the actual parameter thermal actio...
