Description

Technical Field

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

[0002] Rotary valves are crucial components for fluid control, regulating pressure, flow rate, and direction to meet the demands of modern fluid systems. They operate by rotating the valve body to control fluid flow and on / off. The valve body and seat employ a double-plane or spherical structure to ensure superior sealing and flow characteristics. Rotary valves can be operated manually, pneumatically, or electrically, with the appropriate method selected based on the specific application.

[0003] Rotary valves are widely used in petroleum, natural gas, chemical, and power industries. With the continuous development of modern industry, the requirements for the quality and efficiency of fluid control are becoming increasingly higher, which has also promoted the continuous improvement and development of rotary valve technology.

[0004] Currently, the connection mechanism of rotary valves is welded. However, defects such as porosity, slag inclusions, incomplete penetration, and lack of fusion are prone to occur during the welding process. These defects reduce the strength and sealing performance of the weld. The thermal stress generated during welding may lead to local stress concentration, affecting the structural strength and service life of the valve. Once installed, welded valves are very difficult to disassemble and replace, requiring cutting and re-welding. This is not only time-consuming and labor-intensive, but may also damage the pipeline system. Furthermore, poor sealing performance can lead to an increase in the sealing gap, reducing the valve's sealing performance and causing leakage. Leakage not only wastes the medium, but may also pollute the environment and even cause safety accidents. Therefore, an adaptive diameter quick-switching rotary valve connection mechanism is needed to improve the above problems. Utility Model Content

This connection method has strong disassembly, making the maintenance process more efficient.

[0029] A flow meter 204 is fixedly connected to the top of the flow pipe 201. Four nuts 304 are provided on the side of the first flange plate 302. Both the first flange plate 302 and the second flange plate 305 have through holes 303 inside.
