Use of the products :
API pipeline ball valve is suitable for ANSI Class 150~900, working temperature- petroleum, chemical industry, fire power hydropower station of 2800 degrees Centigrade,etc. are on the pipelines of different operating modes, cut off or put through the medium. The suitable medium is: Such medium as petroleum , purified natural gas , acid natural gas , coal gas , water and coal thick liquid ,etc.. The operation mode is as follows, manual, turbine transmission , pneumatic , electronic , angry liquid are linked.
|
Product structure characteristic :
1.In the valve when a of stagnant medium unusually steps up because of changing in temperature, the medium pressure promotes the valve seat to break away from the spheroid, get the result of letting out and pressing automatically, the valve seat resets automatically after releasing pressure.
2.When in case the fire takes place or unusually intensifies to make the valve seat seal and enclose burning to decrease or soften, it is still reliable for valve to operate, meanwhile, valve between flat and spheroid form metal keep in touch to the metal, reach sealed function temporarily, prevent the fire from expanding further , accord with the regulation of APIFA.
3.Is it eliminate device checkable valve flat is it reveal to happen , can delayed in thing reduce the pollution of the valve of medium in discharging to turn on. In working order, at turn on or when imprisonning all , can change gland box , department of valve stem , all valve.
4.The valve seat is besides generally sealing, the ones that especially set up complement and make sealed structure , can play the urgent rescue function while appearing and revealing because the seal is damaged .
5.The position of the valve stem seals and adopts PTFR packing and 0 shape to enclose, is especially suitable for the gas medium. Valve stem sport position adopt high-quality SF lubricate bearing by oneself, is it rub system to be little to make, lower the moment of operating. |
