How to realize the flow adjustment function of manual butterfly valve?
Manual butterfly valve is a common flow regulating device, widely used in various industrial fields. The main principle is to change the section shape of the pipeline by rotating the butterfly plate, so as to adjust the flow of fluid in the pipeline.
The following will introduce several important aspects of the flow control function of the manual butterfly valve:
1. Design of the butterfly plate: The butterfly plate is a key flow regulation component of the manual butterfly valve. In general, the material of the butterfly plate can be selected from stainless steel, carbon steel, cast iron and other materials, according to the specific use of the environment and fluid media to choose. In addition, the shape of the butterfly plate is also very important, usually to choose a rectangle, triangle and other shapes, and consider its opening and closing Angle in the fluid control process.
2. Valve body structure: The valve body structure of the manual butterfly valve must match the shape of the butterfly plate to ensure reliable sealing performance and efficient flow regulation performance. In addition, when purchasing manual butterfly valves, it is necessary to pay attention to the pipe connection mode, applicable pressure and other parameters.
3. Design of the operating mechanism: The operating mechanism of the manual butterfly valve usually adopts a handle or a gear transmission mechanism, which realizes the control of the butterfly plate by rotating operation. In the design need to consider the relationship between valve opening and fluid flow, as well as manual operation torque and efficiency and other factors.
4. The influence of fluid characteristics: The flow regulation function of the manual butterfly valve is affected by the characteristics of the fluid medium, such as density, viscosity, pressure and other factors. When installing and using the manual butterfly valve, the parameters need to be adjusted and optimized according to the actual situation to better play its flow regulation function.
In short, the manual butterfly valve is an important flow regulation device, and its efficient and reliable flow control ability is indispensable for the normal operation of the pipeline system. In order to ensure the best performance and safety, the selection and use of manual butterfly valves need to carefully consider the parameters, and in accordance with the standard operating procedures for use and maintenance.
