Description
Technical field
The invention belongs to valve field, regulate valve especially with regard to one.
Background technology
Be presently used for the regulation valve more employing stop valve of pipeline medium Flow-rate adjustment, its structure include valve body,
Valve seat, spool, valve rod, valve gap, drive mechanism, valve seat is arranged on valve body and imports and exports between passage, in order to
Reducing and close moment, it is mutual with valve seat that valve flowing channel typically uses high in and low out structure, spool lower surface to be shaped with
The sealing surface coordinated, spool upper surface is fixing with valve rod to be connected, by transmission mechanism control spool Lift,
Control the rate-of flow by valve seat, it is achieved the regulation to rate-of flow.The subject matter that this structure exists
Being: when spool Lift is less that velocity of medium is very big, medium is to valve core sealed cover and sealing surface of seat
Wash away very big, reduce the service life of valve, and close for nonlinear change between Lift and flow
System, degree of regulation is poor.In order to reduce medium, valve core sealed cover and sealing surface of seat are washed away, improve and produce
Product service life, in typically using the valve channel outside sealing surface of seat, a circumferencial direction is installed and is shaped with
The sleeve of opening, spool periphery is dynamic with sleeve lining to be coordinated, along with the increase of spool Lift, stream
The quantity of through hole medium circulation increases therewith, reaches to regulate traffic engineering capability, effectively reduces medium to valve base sealing
Washing away of face and valve core sealed cover, improves valve service life.Its major defect is that medium passes through opening
Flow velocity is the highest, and noise is the biggest.
Summary of the invention
It is an object of the invention to the shortcoming existed for prior art, it is provided that one length in service life, flow are adjusted
The joint labyrinth adjusting valve that the linearity is good, noise is low.
Technical scheme includes valve body, valve seat, spool, valve rod, valve gap, and valve seat is arranged on valve body
Import and export between passage, valve body uses high in and low out structure, and spool lower surface is shaped with and cooperates with valve seat
Sealing surface, spool upper surface is fixing with valve rod to be connected, and installs sleeve between sealing surface of seat periphery and valve gap
Assembly, spool periphery is dynamic with sleeve assembly inner round wall to be coordinated；Mainly sleeve assembly is by several many borehole jacks
Cylinder combined set with one heart is constituted, and its inner layer sleeve and outer layer sleeve are formed respectively with several radial direction through hole, two
One sleeve being shaped with some long arc-shaped holes along circular arc direction is installed between the individual sleeve being shaped with radial direction through hole, should
Long arc-shaped holes one end of sleeve connects with the radial direction through hole of its inner barrel, the other end and the footpath of its outer barrel
Connect to through hole；Installing compensating cylinder between sleeve assembly and valve gap, spool uses cylindrical structure, this cylinder
External disc coordinates composition piston cylinder operator with compensating cylinder inwall movable sealing, makes between cylindrical upper and lower end face
There is the through hole of connection compensating cylinder inner chamber and valve outlet passage；Between compensating cylinder and valve body, setting is interconnected
Irrigation channel, one end of this irrigation channel by compensating cylinder lower surface with centre long arc-shaped holes sleeve on every
One long arc-shaped holes connection, the other end connects with the flushing valve on valve body.
Preferably, sleeve assembly uses seven concentric combined sets of porous sleeve to constitute, the two of its inner layer sleeve
Align in individual radial direction through hole two ends with the second sleeve long arc-shaped holes respectively；The radial direction through hole of the 3rd sleeve inner with
The justified of the second sleeve long arc-shaped holes, the radial direction through hole outer end of the 3rd sleeve and the 4th sleeve long arc-shaped holes
One end alignment；The other end of the 4th sleeve long arc-shaped holes aligns with radial direction through hole the inner of the 5th sleeve, the
Align with one end of the 6th sleeve long arc-shaped holes in the radial direction through hole outer end of five sleeves, the 6th sleeve long arc-shaped holes
The other end aligns with the radial direction through hole of outer layer sleeve.
It is an advantage of the invention that sleeve assembly is made up of the concentric combined set of several porous sleeves, each sleeve it
Between through hole be interconnected formation labyrinth flow-path, medium enters by multiple sleeves from the radial direction through hole of outer barrel
Flow out from the radial direction through hole of inner barrel after the deceleration of the labyrinth flow-path of composition and decompression, and from axial every layer
The flow that labyrinth flow-path flows out is equal, tuning linearity is good, sealing surface is washed away little, length in service life by fluid,
Noise is low.
