La description
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 sealing ring of polytetrafluoroethylene is
burned and the leakage occurs. The fire seal ring is set up between
the ball and the valve seat. When the seal is destroyed, the seal
ring of the seat is pushed quickly to the sphere to form the seal
of metal and metal. To a certain degree of sealing effect. The fire
resistance test meets the requirements of APl6FA and APl**7.
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 full off, unload the pressure of the
cavity, can directly replace the packing; can discharge the
retention of the medium, reduce the pollution of the medium to the
valve.
