1. The seat of the cavity plate spring deformation, sealed performance is bad, so that the silicon powder into the cavity, the seat plate spring deformation caused by plate spring blocking expires, ball valve is seat lock and so cannot be good for the switch. 2. body between the ball and the lumen of the Industrial Valves switch into the silicon powder, which caused valve ball lock cannot be smoothly switch. But need a working condition, cause this is in the case of silicon powder damp can stick inside the cavity. And silicon powder in the case of dry or fluid is not cause of this lock. If silicon powder in the case of dry or fluid situation that is the first cause, holding in death of the cavity of silicon powder into the seat plate spring deformation. To solve the above two methods of produce lock valve: 1. Zigong valve factory is the 'O' type ball, double seat, plate spring loaded structure, the seat seal design into a wide face scraper type structure, can remove the stick when valve switch in spherical silica powder, has since cut self-cleaning function, plate spring with double graphite sealing structure, at the same time of the valve seal, plate spring also sealed, medium will not enter the cavity plate spring deformation, disable plate spring not be blocked, can meet the needs for a long time. 2. On silicon powder damp block valve lumen lock can't switch this special situation, we generally advise clients to strengthen silicon powder or switch to the drying effect of zigong Industrial Valves factory of v-shaped ball Industrial Valves, to thoroughly solve the congestion problem.
