What is the function of relief valve?
Relief valve is a valve used to regulate the pressure of a fluid (such as water or gas). Its main function is to reduce the pressure of the fluid and keep the outlet pressure at a stable level. The following are the main functions of the pressure reducing valve:
Pressure regulation: The relief valve adjusts the flow rate and kinetic energy of the fluid by changing the throttling area, thereby changing the pressure loss of the fluid to achieve the purpose of reducing pressure.
Pressure stability: The relief valve relies on the regulation of the control and regulation system to balance the fluctuation of the pressure behind the valve with the spring force, so that the pressure behind the valve remains constant within a certain error range.
Protect equipment: The relief valve can protect the equipment from damage caused by excessive pressure, extend its service life, and improve the stability and safety of the system.
Water saving and pressure reduction: In high-rise buildings, urban water supply networks, mines and other occasions, the relief valve achieves the effect of water saving and pressure reduction by reducing water pressure and leakage rate.
Industrial application: In industrial production, the relief valve is used to accurately control the steam pressure, protect the steam system, and ensure that the steam drives the turbine to work smoothly and efficiently.
Chemical industry: In chemical production, relief valves are used to control reaction pressure, ensure smooth reaction, and improve the efficiency of chemical reactions and product quality.
Offshore platforms and long-distance pipelines: In offshore platforms and long-distance pipelines, relief valves are used to maintain pipeline pressure in a safe range at all times, ensuring safe and efficient transportation of natural gas.
In short, relief valves play an important role in many fields, from households to industries, from water conservancy to chemicals, and are indispensable equipment.
