The main uses of valves include the following aspects:
(1) Flow control: The valve can adjust the flow of fluid as needed, thereby controlling the speed and pressure of the fluid in the pipeline. For example, a regulating valve can increase or decrease the flow of a liquid or gas as needed.
(2) Flow direction control: Valves can ensure that the flow direction of fluid in the pipeline meets the requirements. By opening or closing a valve, the flow of fluid can be changed so that it can be directed to a specific location or device.
(3) Stop flow: The valve can be completely closed to prevent the flow of fluid. This is useful when the fluid supply needs to be stopped or cut off, such as in an emergency or when repairs and replacement of plumbing fixtures are being carried out.
(4) Pressure regulation: Certain types of valves can be used to regulate the pressure of fluids. By adjusting the opening of the valve, the pressure of the fluid can be increased or decreased to meet specific process requirements.
(5) Fluid distribution: Valves can guide fluids to different pipes or equipment to achieve fluid distribution and control. This is very important for complex industrial processes and systems.
