Problems solved by technology
[0004] The technical problem to be solved by the present invention is that due to the complex working conditions of the existing voltage stabilizer safety valve, the discharge working medium may be a complex situation of various water qualities under accident conditions, and there is no test and detection for the action performance of the voltage stabilizer safety valve. As a result, its performance cannot meet the requirements of use. A pressure stabilizer safety valve action performance test system with water as the working fluid is provided. Design indicators and performance parameters provide a basis for the design improvement and engineering application of safety valves

Provide basis for design improvement and engineering application of safety valve. It solves the existing problem that it is impossible to test and detect the action performance of the safety valve of the voltage stabilizer, resulting in its performance not meeting the requirements for use.
Description
technical field [0001] The invention belongs to the thermal engineering research field of safety valves, and in particular relates to a safety valve action performance test system and test method using water as a working medium. Background technique [0002] The safety valve of the pressurizer is an important safety equipment of the nuclear power plant. During the operation of the nuclear power plant, the safety valve of the pressurizer has the function of ensuring the integrity of the pressure boundary of the reactor coolant system. In special cases, the medium passes through the device in the form of steam or water. Release to ensure that no overpressure accident occurs in the primary circuit. [0003] Due to the important role of the safety valve of the regulator, verification tests must be carried out during the design and development process to study the action performance of the safety valve under different conditions, including set pressure, discharge pressure, reseat...
