High performance fluorine ball valve is designed according to GB/T12237 standard and enterprise standard. It is mainly used to control the on-off of industrial pipeline materials. It has the advantages of small flow resistance, simple structure, reliable sealing performance, rapid opening and closing, and is suitable for highly corrosive media of acid, alkali and salt with temperature ranging from - 29 ° C to 180 ° C. Products are widely used in petroleum, chemical, chlor-alkali, pharmaceutical, mineral processing and other fields. This series of ball valves has the following structural features: 1.  Less material accumulation and anti-crystallization The liner of the body is made of imported fluorine material, which has good corrosion resistance and wear resistance. The body is compact in design and small in clearance, which can effectively reduce the accumulation of materials and prevent the accumulation of crystals from affecting the sealing effect. 2. Blowout proof stem The ball and stem are integrally cast, and the surface is equipped with through holes and dovetail grooves, which can make the inner liner closely combine with the metal parts without separation. When the valve cavity pressure is abnormal, the stem will not blow out. 3.Convex Sealing Structure of Body and Bonnet The valve body and bonnet are equipped with a sealing convex and dovetail groove structure, which can prevent the liner from falling off and effectively prevent the leakage between the bodies. 4.Self-Compensating Design for Energy Storage U-Type Seat  The body and bonnet sealing seats are equipped with U-shaped grooves. The pre-tightening force is applied to the seal through the valve body and bonnet, and the sealing seat absorbs the tightening force. When the valve is used for a long time, the sealing surface of the body and bonnet will be worn. At this time, the sealing seat releases the pre-tightening force, which can effectively compensate the sealing surface and protect the sealing effect of the valve. 5.Handle with locking device The handle and packing gland are equipped with corresponding lock holes. The lock holes in the opening and closing positions must be aligned, and required convenient locking, so that the valve will not be misoperated to guarantee the using safety.
