Description
Technical field
This utility model relates to a kind of regulation ball valve.
Background technology
Ball valve is a kind of conventional valve, its structure generally comprises valve body, valve gap, spheroid, valve rod and the drive mechanism driving valve rod to rotate, described valve body is provided with valve pocket and the medium entrance being conducted with valve pocket and media outlet, in described spheroid is arranged on described valve pocket and is connected with valve rod.
At present, its spheroid of traditional ball valve is when less aperture, and its flow just reaches maximum.In other words, do not has linear relationship between fluid flow and the aperture of spheroid of ball valve, therefore, it is impossible to the flow of ball valve is carried out linear accurately regulation.
Additionally, known in those skilled in the art, when liquid medium in pipeline flows through the throttling section of valve, flow velocity raises, static pressure reduces, when medium from throttling section until the static pressure of valve export decreases to or below this medium saturated vapour pressure at a temperature of valve inlet, partially liq will be vaporized into gas, forms the phenomenon that gas-liquid two-phase coexists in valve, and this phenomenon is referred to as " flash distillation ".According to principle of hydrodynamics, flass can be judged by equation below:
P1-P2=FL 2(P1-Pc)；
Wherein: P1-inlet pressure；
P2-outlet pressure；
FL-pressure drop coefficient；
PcStatic pressure at-throttling section flow rate speed peak；
PvThe saturated vapour pressure of-described liquid；
Work as P1-P2≥FL 2(P1-PV) time, liquid flows through throttling section and arises that flash distillation, now will produce a large amount of bubble in valve pocket.If downstream pressure P2It is not maintained at saturated vapor pressure PvHereinafter, but the most suddenly rise after throttling section, the bubble that flash distillation produces will pressure-rupturable return liquid, this process is exactly cavitation.When producing cavitation, the bubble that flash distillation produces bursts in succession, all energy that a large amount of bubble eruptions produce concentrate on breakdown point, form great impulsive force, if and breakdown point is just near valve or inner-walls of duct, impulsive force can corrode many thickly dotted apertures at material surface, is more gradually expanded into cave, finally slowly tear material surface, here it is " cavitation erosion " phenomenon of fluid.Cavitation erosion meeting band in industrial process control system is served and is significantly endangered:
1, the corrosion to material is accelerated.Metal material surface can form the protecting film of thin layer under normal circumstances, and protection material exempts from corrosion to a certain extent, and protecting film can be destroyed within the shortest time by cavitation, makes medium accelerate the corrosion rate of material；
2, noise is produced.A large amount of bubbles that flash distillation is formed burst the most in succession, define the noise that frequency is wider, not only affect the physical and mental health of field personnel, and also the living environment to surrounding resident causes serious harm；
3, judder is caused.A large amount of bubble eruptions produce lasting dither, easily cause the strong resonance of field pipes and miscellaneous equipment, even result in equipment fault, cause serious accident time serious.
Therefore, it is necessary to this is improved.
