Welded orifice platesAs a commonly used pipeline equipment, it plays an important role in many industrial fields. Its main functions include the following aspects:
1. Flow measurement.
Welded orifice plates can be used to measure the flow of fluids in pipes. By installing the orifice plate in the pipe, a throttling device can be created so that the fluid creates local resistance as it passes through the orifice, resulting in a pressure difference. The flow rate of a fluid can be calculated using a flow calculation formula based on the relationship between the pressure difference generated before and after the orifice plate and the fluid flow rate. This measurement method has high accuracy and reliability, so it has been widely used in petroleum, chemical industry, electric power and other fields.
2. Pressure regulation.
Welded orifice plates can be used to regulate the pressure of the fluid in the pipeline. By changing the size of the orifice plate, the resistance of the fluid as it passes through the orifice plate can be adjusted, and the fluid pressure can be adjusted. In industrial production, welded orifice plates are widely used in various pressure control systems, such as pressure reducing valves, safety valves, etc., to ensure pressure stability and safety in the production process.
3. Prevent fluid backflow.
Welded orifice plates can be used to prevent fluid backflow. The backflow of the fluid can be stopped due to the resistance formed by the orifice plate in the pipe. In the application scenarios that need to prevent fluid backflow, such as water supply pipe networks, chemical material transportation, etc., welded orifice plates can play a good role in preventing backflow.
Fourth, control the flow direction of fluid.
Welded orifice plates can be used to change the flow direction of the fluid. By installing orifice plates in different orientations in the pipes, the fluid can be directed to flow in the specified direction. This application is especially common in petroleum, chemical and other fields, such as setting orifice plates in different directions in oil and gas pipelines to achieve oil and gas separation or adjust oil and gas flow direction.
5. Reduce fluid noise.
Welded orifice plates can be used to reduce fluid noise. Due to the eddy currents and friction generated by the fluid as it passes through the orifice plate, these forces consume some of the energy and produce noise. By rationally designing the shape and size of the orifice plate, the fluid noise can be effectively reduced and the production environment can be improved. For example, having proper orifice plates in oil pipelines can reduce noise pollution during fluid transfer.
