safety relief valve​

     Safety holding pressure relief valve, also known as pressure reducing valve or safety relief valve, is a valve used to maintain stable internal pressure in pipeline systems. It can automatically open when the pipeline pressure exceeds the preset value, releasing excess pressure to prevent pipeline rupture or other safety accidents. At the same time, when the pressure drops within a safe range, the valve will automatically close to maintain the normal operating pressure of the pipeline system. This type of valve is usually installed on the pipelines of high-rise building water supply systems, fire water supply systems, and other water supply systems to ensure the safety and reliability of the system.

Working principle
    The safety holding pressure relief valve is usually composed of main valve, pilot valve, ball valve, pressure gauge and other components. In normal working condition, if the pressure in front of the valve is lower than the set value, the pilot valve closes and the main valve remains closed. When the pressure inside the pipeline rises to the set value, the pilot valve opens, allowing a portion of the water flow to pass through, thereby reducing the pressure in front of the main valve. If the pressure continues to rise, the main valve will also open, releasing more water flow to further reduce the pressure. When the pressure drops to a safe range, the pilot valve and main valve close in sequence to prevent water flow from continuing, thereby maintaining a stable pressure in the pipeline system

Advantage
Safety holding pressure relief valves are generally connected to gate valve due to their ability to effectively prevent and reduce water hammer effects, avoid pipeline rupture, protect water pumps, and maintain pipeline safety. They can also be used in various water supply systems in conjunction with check valve, filters, and other valve components. In addition, these valves also have the characteristics of easy operation, low maintenance costs, and good energy-saving effects, which can improve the efficiency and safety of the entire system.

In summary, the safety holding pressure relief valve is a key component for ensuring the safe operation of fluid delivery systems. Its precise working principle and strict technical specifications are crucial for preventing potential safety risks. Welcome to inquire!
