Description

Pneumatic regulating valve with filtering structure Technical Field The utility model relates to the technical field of pneumatic regulating valves, in particular to a pneumatic regulating valve with a filtering structure. Background The pneumatic regulating valve is industrial control equipment which uses compressed air as a power source and utilizes a pneumatic actuating mechanism to drive a valve core to move, thereby realizing automatic regulation of flow, pressure, temperature or liquid level and other technological parameters of fluid media (such as gas, liquid, steam and the like), and the conventional pneumatic regulating valve is usually provided with a filtering structure in order to avoid blockage inside a valve body. In the prior art, after the filter structure is used for a long time, the filter holes of the filter structure are easy to be blocked by impurities, so that the filter structure is difficult to clean and the filter effect of the filter structure is also influenced, meanwhile, the filtered and intercepted impurities are difficult to clean, the centralized treatment of the impurities is difficult to realize, and a plurality of inconveniences are brought to the normal use and maintenance of the pneumatic regulating valve.
