The main function of a pressure reducing valve is to regulate the pressure in a pipeline system. Specifically, the pressure reducing valve reduces the inlet pressure to a certain required outlet pressure through throttling and regulation of the opening and closing parts, and automatically maintains the outlet pressure stable by relying on the energy of the medium itself.
From the perspective of fluid mechanics, a pressure reducing valve is a throttling element with variable local resistance. It changes the flow rate and the kinetic energy of the fluid by changing the throttling area, thereby causing different pressure losses to achieve the purpose of reducing pressure.
Pressure reducing valves are widely used in many fields such as petrochemicals, electricity, water treatment, pharmaceuticals, and construction, especially in occasions where high requirements for fluid pressure control are required. In applications such as water supply systems and fire protection systems, pressure reducing valves can stably regulate the water flow pressure in the pipeline to ensure that a constant pressure output is provided in the system, which helps to protect the pipeline system, water pumps and other equipment from excessive or low pressure and extend the service life of the equipment.
In addition, the pressure reducing valve also has a wide pressure regulation range, which can adapt to the pressure requirements of different fields and equipment, and ensure the stable operation of the system by quickly responding to changes in system pressure. At the same time, the structure of the pressure reducing valve is relatively simple and clear, easy to install and maintain, and reduces the maintenance cost and difficulty.
