Patent number: 11773995Abstract: A relief valve device having a valve disc positioned above a nozzle, a disc holder surrounding an outer periphery of the valve disc, and a spring surrounding a valve stem. A bottom section of the nozzle is connected to a valve body and a top section of the nozzle is connected to the valve disc. An interior surface of the nozzle contains at least one groove having a circular cross-sectional profile. The relief valve device prevents flow through the nozzle when a pressure at an inlet of the nozzle is below a predetermined force of the spring. When the pressure exceeds the predetermined force of the spring the valve stem is moved linearly through the longitudinal axis of the spring to displace the valve disc from sitting atop the nozzle and permit flow through the nozzle.Type: GrantFiled: February 23, 2023Date of Patent: October 3, 2023Assignee: Prince Mohammad Bin Fahd UniversityInventors: Esam Jassim, Abdullah Alhamdan
