Description

Technical Field

[0001] This utility model relates to the field of valves, and in particular to an adaptive caliber quick-switching rotary valve. Background Technology

[0002] The primary function of a rotary valve is to control fluids, including liquids, gases, and steam. It can control the pressure, flow rate, and direction of the fluid, thereby achieving the purpose of controlling the fluid system. Therefore, the rotary valve is an indispensable component in fluid control systems.

[0003] The function of rotary valves varies depending on the application. In many fluid systems, rotary valves are commonly used to control the flow rate and direction of fluids, such as regulating flow in pipelines and preventing backflow. In the oil and gas industry, rotary valves are mainly used for pipeline shut-off and flow regulation. In chemical production, rotary valves can be used in processes such as mixing, separation, interference, level control, compression, and purification. Therefore, rotary valves play an important role in various fluid systems.

[0004] A rotary valve works by using the rotation of its body to control the on / off state and flow rate of fluid. A rotary valve mainly consists of a valve body, valve seat, valve stem, and valve cover. When the valve stem rotates, the valve body moves, engaging or disengaging with the valve seat, thereby controlling the on / off state and flow rate of the fluid.

[0005] To reduce valve friction and improve sealing performance, rotary valves typically feature a double-plane or spherical design for the valve body and seat. This design ensures better sealing and flow characteristics. Additionally, the valve core of a rotary valve is usually made of hard alloy material to guarantee its wear resistance and corrosion resistance.

[0006] The working principle of a rotary valve also includes the selection of the operating method. Rotary valves are typically available in manual, pneumatic, and electric operation modes. Manual operation is suitable for low-flow and low-pressure applications, pneumatic operation is suitable for high-flow and high-pressure applications, and electric operation is suitable for applications requiring remote control and monitoring of the valve.

[0007] Traditional rotary valves have a fixed orifice diameter and cannot be adjusted according to different fluid flow requirements. This leads to the need to frequently change valves of different orifice diameters under different operating conditions, increasing costs and maintenance time. When it is necessary to quickly switch the fluid flow direction or flow rate, the existing rotary valves have a slow switching speed, which cannot meet the needs of high-efficiency production. Therefore, an adaptive orifice diameter fast switching rotary valve is needed to improve the above problems. Utility Model Content

[0008] To address the issue that traditional rotary valves have a fixed orifice diameter and cannot be adjusted according to different fluid flow requirements, resulting in frequent replacement of valves with different orifice diameters under different operating conditions, which increases costs and maintenance time, and that existing rotary valves have a slow switching speed when it is necessary to quickly switch fluid flow direction or flow rate, which cannot meet the needs of high-efficiency production, this utility model proposes an adaptive orifice diameter fast switching rotary valve.
