[0002] A hydraulic valve is an automated component operated by pressurized oil. It is controlled by the pressure oil of a pressure-regulating valve and is usually used in combination with an electromagnetic pressure-regulating valve. It can be used to remotely control the on / off state of the oil, gas, and water pipeline systems in a hydropower station. As an important component of the hydraulic valve, the quality of the hydraulic valve core determines the quality of the hydraulic valve. Therefore, the assembly of the hydraulic valve core needs to ensure a certain torque value and a certain installation angle to ensure the airtightness and installation quality of the hydraulic valve after installation. The existing hydraulic valve core is installed manually, and the angle cannot be precisely controlled during the installation process, resulting in airtightness problems. In response to this detection requirement and the problems arising from existing detection methods, this application proposes a solution. Summary of the Invention
