The pressure safety relief valve is the key component in any system where pressure rising could be hazardous to the safety of the workers as well as the plant. Safety valves are designed to provide protection from overpressure in steam, gas, air and liquid lines. Safety valve should be a reliable and more precise design that will be working at more accuracy. In refinery distribution sector, safety is of prime important. Home appliance is also required pressure safety in the modern era. The key requirement of the process is to relieve this pressure rise in no time. Old technological design valves are unable to fulfill that requirement. Design and analysis of an emergency safety valve. From the data, the suitable valve is designed using FEA. In this project is focused on change old technological safety valve with new 3D prototype valve that has less equip parts, where in it is required that flow be shut off when a certain pressure is reached. Electronic valves are available, however the intent of this design project is have a total mechanical system, which has an in built response mechanism. The working environment is hazardous & explosive. This safety valve is an auto regulate operating valve used as tertiary safety arrangement for critical applications.

INTRODUCTION Pressure relief device protects process equipment from the hazards of high pressure in a process. It operates by opening at a recognize pressure and ejected mass from its. The ejected mass containing energy which is reduced during pressure realized. The purpose of design a safety valve to determine the physical and mechanical properties of this and optimizing the performance during critical condition. In presently used safety valve sizing standards the gas discharge capacity is based on a nozzle flow gas theory. At high pressures or low temperatures real-gas effects can no longer be neglected, so the discharge coefficient corrected for flow losses cannot be assumed constant anymore. Also the force balance and as a consequence, the opening characteristics will be affected. In former Computational Fluid Dynamics studies, valve capacities have been validated at pressures up to 1.5- 10 bar with focusing on the opening characteristic. In this paper, alternative valve sizing models and a numerical FEA tool are developed to predict the opening characteristics of a safety valve at moderate higher pressures. The first alternative valve sizing method is the real-average method that averages between the valve inlet and the nozzle throat at the critical pressure ratio. The second real-integral method calculates small isentropic state changes from the inlet to the final critical state. In a comparison, the simplest ideal method performs slightly better than the real-average method and the dimensionless flow coefficient differs less than 3% from the most accurate real-integral valve sizing method. Benchmark validation test cases from which field data is available are used to investigate the relevance of the physical effects present in a safety valve and to determine the optimal settings of the ANSYS workbench. Shock strength in a safety valve flow is small enough to be accurately computed. In digital prototype is tested this model at a statically. In this design, Safety valve is operating with normal pressure and adjust higher pressure by releasing access mass through escapes hole on body. Spring loaded valve is adjusting pine of safety valve with compression and expansion of spring by storing and release internal energy of helical spring.
