Differential regulating valve.
Background technology
The conventional design structure of Multistage decompression high-differential-pressure regulating valve is labyrinth type, but is aimed at medium for dirty and contain
The occasion of solid particle fluid, if during using labyrinth type multilevel decompression regulating valve, multiple labyrinth paths are easy to by solid
Granule medium blocking, the using effect that multilevel decompression control valve can be had a strong impact on or the effect for losing step-down completely.Therefore it is multistage
The design of decompressing regulating valve with high pressure difference directly affects the using effect of whole valve, serious it may happen that accident or making
Plant downtime.For on the technical performance index, the leakage class of the Multistage decompression high-differential-pressure regulating valve of this structure is IV grade,
In valve closing, sealing surface is easy to be influenceed by erosion attack the sealing effectiveness of valve.
Labyrinth type multilevel decompression high-differential-pressure regulating valve design as shown in Figure 3,4, labyrinth type multilevel decompression regulating valve
Design principle is that many ring-shaped discs are stacked up, and forms the throttling passage by controlling valve, and electricity consumption burn into laser
（Line）The modes such as cutting make ring-shaped discs constitute fluid passage, and stream is tortuous, forces flow restriction and is passed to complications
The runner of change, and fluid passes through the purpose that a bent angle just plays one-level step-down often.In this process, fluid is consumed
Kinetic energy, reduce rate of flow of fluid, reach the effect of multilevel decompression.But medium is aimed at for dirty and contain solid particle stream
The occasion of body, if using maze-type structure multilevel decompression regulating valve when, because labyrinth path groove is narrow and be straight
Angle is turned round, therefore multiple labyrinth flow-paths are easy to be blocked by solid particle medium, have a strong impact on the use of multilevel decompression control valve
Effect loses the effect of step-down completely.
The content of the invention
In view of the problem that above-mentioned prior art is present, a kind of Cascade multilevel decompression High Pressure Difference regulation of the utility model offer
Valve design, in valve working, fluid is throttled by the step that multiple step plug is risen as high as the banks so that the fluid edge of high pressure drop
The bending flowing of valve core axis directions, is constantly turned by the circulation area formed between valve element and valve cage, bump flow, adopted
The radial and axial method for designing being combined during with flow of fluid, make the High Pressure Difference of medium along valve core axis direction it is continuous under
Drop, the pressure drop of effective control fluid and flow velocity, prevent fluid from producing flash distillation and cavitating.
To achieve the above object, the technical scheme for being used is the utility model：A kind of Cascade multilevel decompression High Pressure Difference
Regulating valve, including valve body, valve seat pad, valve seat, valve seat Upper gasket, valve cage, valve element, bonnet gasket, bonnet, it is characterised in that：

On valve seat, the valve cage loads in valve body, and the lower end of valve cage is arranged on the end face of valve seat and valve seat Upper gasket, and the valve element leads to
Cross valve cage to load in valve body, the bonnet is placed and is fixed on valve body, and bonnet gasket is set between bonnet and valve body.
The characteristics of the utility model is：The utility model be specific to dirty and occasion containing a small amount of solid particle and
The through type or angie type multilevel decompression high differential pressure control valve of design, big with stream cavity space, the characteristics of self-cleaning function is strong, it can
The problems such as with the blocking, erosion and the sealing surface wear that effectively solve multilevel decompression control valve.
The utility model is mainly used in precise control high temperature, high pressure, High Pressure Difference and the stream containing solid particle fluid
Amount, the occasion of pressure and temperature, the valve combine the design advantage of the multilevel decompression control valves such as porous type, labyrinth type, can
The liquid cavitation erosion that especially liquid containing solid particle is produced is prevented, high-velocity fluid is reduced and trim is washed away, reduced
The noise that fluid is produced.
It is dirty and containing the occasion of solid particle fluid to be directed to medium, is designed by the special construction of valve element, valve cage
Make the fluid of High Pressure Difference step pressure reducing in the space that valve cage and valve element are formed.
