Background
The fluorine lining ball valve uses a ball body with a circular through hole as an opening and closing part, and the ball body rotates around the central line of a valve body along with a valve rod to realize the opening and closing of the valve. A special mould pressing process is adopted, so that the sealing surface is compact and good, and the valve achieves zero leakage by combining the V-shaped PTFE filler; the ball body and the valve rod are cast into a whole, so that the possibility that the valve rod is punched out of the pressure-bearing part due to pressure change is avoided, and the safety in use is fundamentally ensured; the process of full plastic lining is adopted, and the high corrosion of the medium is resisted.
The fluorine-lined ball valve consists of a pneumatic piston type actuating mechanism and an O-shaped fluorine-lined ball valve. The inner cavity of the valve body and the disc plate are lined with the polyfluorinated ethylene propylene which is corrosion-resistant and ageing-resistant by adopting a high-pressure injection molding process, so that the valve body has reliable corrosion resistance and sealing property. The device is mainly used for adjusting or cutting off strong corrosive media such as acid and alkali in the production process. The fluorine-lined ball valve is mainly used for adjusting or cutting off strong corrosive media such as acid and alkali in the production process. The automatic control system is widely applied to automatic regulation and remote control systems in the industries of food, environmental protection, light industry, petroleum, papermaking, chemical industry, light spinning, electric power and the like.
In the fluid medium pipeline, the ball valve is an effective and necessary cut-off device, in order to clear away impurity and filth in the fluid medium, keeps pipeline's cleanness and unblocked, sets up the filter in pipeline and then is the essential important equipment of improvement fluid quality, but the filter is easy to be blockked up in long-time work in the pipeline, causes the pipeline transportation volume to descend, and it is a huge engineering again to take out the washing with the filter in the pipeline, consuming time and wasting force.
