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 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 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 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
