I would appreciate it if the experts could help me figure out how to calculate the heat input required to account for the liquid expansion of safety valves

First, it is necessary to determine various overpressure conditions and identify the source of heat in order to determine the amount of heat transferred. For specific calculations, refer to HG/T 20570.2-95 \"Installation and Selection of Safety Valves\", SY/T 10043-2002 \"Guidelines for Pressure Relief and Pressure Reduction Systems\", and SY/T 10044-2002 \"Recommended Practices for the Sizing, Selection, and Installation of Pressure Relief Devices in Refineries\". Or just look at API 520 and 521 – anyway, other standards also copy from them; P
