Electronically Controlled Pressure Relief Value For Water Pipeline Systems
Abstract: The present invention relates to Electronically controlled pressure relief valve for water pipeline system which is designed to regulate water pressure in a pipeline using real-time data and automated control. India, being predominantly rich in agricultural economy, relies heavily on agriculture for livelihood, food security, and economic development. Efficient irrigation systems 10 play a critical role in ensuring the sustainability and productivity of agricultural practices. With the increasing dependence on precision irrigation methods such as drip and sprinkler systems, maintaining optimal water pressure has become essential for maximizing yield. 15 20 Currently, the pressure regulation in irrigation pipelines is managed using mechanical Pressure Relief Valves (PRVs) that operate through spring-based mechanisms. While these valves are widely used, they lack the precision required for modern irrigation demands and are prone to malfunction due to rusting and wear, particularly when used in water-based applications. In contrast, electronic pressure control systems are well-established in gas and air pipelines, offering better accuracy and responsiveness. However, such electronic solutions have not been effectively implemented for water-based PRVs, especially in agricultural settings. The present invention addresses this gap by introducing a novel electronically controlled PRY system for water pipelines. This system integrates a pressure sensor, a microcontroller, and a motor-driven butterfly gate valve to regulate and release pressure in a controlled and precise ; . 25 manner. The pressirre sensor monitors the pipeline pressure in real time and transmits the data to the microcontroller. Based on predefined thresholds, the microcontroller activates the motor to adjust the valve position, thereby maintaining the desired pressure. The system also facilitates the release of trapped air during pipeline startup, enabling faster water flow and reducing the risk of pipe damage
