Ball for occasions titanium plate

Typically, two-position adjustment, strict sealing performance, mud , wear , necking channel , opening and closing action quickly ( 1/ 4 turn open and close ) , high-pressure cutoff (large pressure ) , low noise, there is the phenomenon of cavitation and gasification , a small amount of leakage into the atmosphere , a small operating torque , fluid resistance of the piping system, the recommended valve . As the ball is usually rubber, nylon and PTFE plastic strap seals material as the seat , so its use is limited by the valve seat ring material . As of action is to rely on the metal ball in the role of the media sphere , pressing each other between the plastic seat to complete ( floating ball valve ) . Valve seat ring at a certain contact pressure, elastic-plastic deformation occurred in some areas . This distortion can be compensated for manufacturing precision and surface roughness of the sphere , to ensure the valve pull tight straps performance . Also, because the ball valve seat ring is usually made ​​of plastic , it is in the choice of the structure and properties of ball , taking the ball of fire and plastic security seal , especially in the petroleum, chemical, metallurgy and other sectors , flammable, explosive media the types of equipment used in the system and the pipe valve, should pay attention to fire and fire . Ball also applies to the lightweight construction , low cut ( pressure difference ) , piping systems corrosive medium. In the low temperature ( cryogenic ) equipment and piping systems can also be used ball . In the metallurgical industry, oxygen pipeline system , use to skim over the ball rigorous process .
When the oil pipeline and gas pipeline to be laid in the main line in the ground , use a full-bore welded ball valve .
Require adjustment during the performance , the need to use special structures ball with V -shaped opening . In the petroleum , petrochemical, chemical, power, urban construction, the operating temperature above 200 ℃ piping systems can use metal -to-metal sealing ball valve .

Ball analytical composition titanium plate

The main valve seat ring material is polytetrafluoroethylene (PTFE). It is almost all chemicals are inert and has a low coefficient of friction , stable performance, easy to aging , wide temperature and excellent tamper proof seals performance integrated features . However, the physical properties of PTFE has a higher coefficient of expansion of the cold sensitivity and poor thermal conductivity, the valve seat tamper proof seal requirements must be designed around these characteristics. The seat seal plastic material, including aliphatic and PTFE Teflon , nylon and other materials .
However , when the sealing material is hardened , the reliability of the pull tight security seals should be destroyed , especially in the case of low pressure differential .
Additionally , such as nitrile rubber, synthetic rubber , can be used seat material , but it applies to the media and to the use temperature range is limited . Further , non-lubricated , synthetic rubber ball stuck easily .
In order to meet the high temperature , high pressure , strong erosion, long life and other requirements of industrial applications , the last decade, metal seated ball valve has been a great development. V- ball valve for regulating the flow also developed rapidly .
Especially in industrialized countries , the ball valve structure continue to improve, as used in the petroleum, natural gas pipeline fully welded ball valve , lift rod ball , ball cracker with temperature regulating valve V -shaped openings , etc. , so that the ball valve technology to achieve a whole new level .
