Prediction Method of Pilot Operated Safety Valve Setting Pressure
Taking the self-developed pilot operated safety valve as the research object,the research on the prediction method of setting pressure is carried out for the pressure-sensing control structure of the pilot valve.According to the analysis of action function and structural principle,a way to measure the integrating preload force is proposed and a special sensor is developed.After adaptive modification of the prototype and installation of the sensor,relevant cold state experimental studies are carried out,and the results show that:the monitoring data of the key force value can be used for the prediction of the setting pressure of the safety valve,but it is necessary to further consider the influence of the operating parameters such as temperature and the design parameters of the valve structure,and optimise the prediction algorithm.
