Description

Technical Field

[0002] A valve is a device used to control the direction, pressure, and flow of a fluid in a fluid system. Existing valves, such as the iris valve with a novel locking mechanism and a control ring disclosed in the invention patent with publication number CN101631504B and the iris aperture variable valve disclosed in the invention patent application with publication number CN112228579A, can all achieve control of the flow of gas or liquid.

[0003] However, it was found during use that when regulating the flow of gas or liquid containing particulate matter, an ultra-high temperature gas flow regulating valve disclosed in the invention patent with publication number CN113339517B or a liquid flow regulating valve disclosed in the invention patent with publication number CN118030875B is generally used, but it is not convenient to flexibly adjust the flow. When using the existing iris valve, during the closing process, the particulate matter in the gas or liquid is easily stuck between multiple blades, affecting the sealing effect of the valve. The temperature of the gas or liquid and the surrounding environment will also affect the sealing effect of the iris valve. When the gas or liquid flows through the valve body, the particulate matter therein is easy to hit multiple blades, affecting the service life of the valve. In addition, the existing valves are not convenient for remote monitoring and data transmission, resulting in poor practicality. Therefore, a valve system with a long-distance monitoring function is urgently needed to improve the above problems. Summary of the invention
