الوصف

1, Operation saving power: the ball is supported by the upper and lower bearings to reduce friction and eliminate the excessive torque caused by the import pressure to promote the huge seal load formed by the ball and the sealing seat.



2, The sealing performance is reliable: the PTFE single material seal ring is embedded in the stainless steel seat. The end of the metal seat is equipped with a spring to ensure enough pretightening force. When the valve is worn during the operation, the valve continues to ensure good sealing performance under the action of spring.



3, Fire protection structure: in order to prevent the emergence of sudden heat or fire, the polytetrafluoroethylene sealing ring is burned and the leakage occurs. The fire seal ring is set up between the ball and the valve seat, and the sealing ring of the seat is quickly pushed to the sphere to form the seal of metal and metal under the effect of the spring force. To a certain degree of sealing effect. The fire resistance test meets the requirements of APl6FA and APl607.



4, Automatic pressure relief function: when the valve medium pressure of stagnation in the medium exceeds the pre force of the spring, the seat back out of the ball, to achieve the effect of automatic pressure relief, the valve seat automatically recovered after pressure relief.



5, Excretory pipeline: the valve body is set up and down the discharge hole, can check the valve seat leakage, in the work, when the valve is in full open or all off, unload the pressure of the middle cavity, can replace the filling directly; can discharge the retention of medium cavity, reduce the pollution of the medium to the valve£¬€š
