Description
Technical field
Asymmetric variation core pipe valve of the invention belongs to valve field, is in the core pipe stem nut series of my original invention
Conventional core pipe valve plate block subfamily, it has flexible characteristic, transforms in conventional pressure medium higher than normal pressures
When, automatic adjustment, decompression, limited current state are transformed by conventional circulation status, in addition, pressure medium lower than normal pressures or
When person's upstream pressure loses pressure source, it is also equipped with the function of check-valves.
Background technique
Currently, without a kind of valve can rely on oneself make a variation circulation area on the basis of, realization rely on oneself non-return, adjust, subtract
Pressure, current limliting.
Summary of the invention
The object of the present invention is to provide asymmetric variation core pipe valves, meet production and energy-efficient requirement, reduce valve
Acquisition expenses, producing cost and maintenance cost.
Asymmetric variation core pipe valve is mainly technically characterized by: the valve core tube is connection pressure vessel, press device and
The coaxial sleeve II through the sleeve I of valve body, body cavity and valve body of the fixing piece of medium pipe network；In the middle part of valve core tube
There is axial interlayer, interlayer is made of the intermediate pipeline section of the valve core tube of kernel and kernel radial radiation；The axially adjacent both sides of interlayer
It is at least one radial recirculation hole of input section and deferent segment respectively；Around the annular spool of interlayer and the annular of II throat of sleeve
Valve seat constitutes sealing pair；Input section and sleeve I and deferent segment and sleeve II are that shaft hole mode cooperates its at least one engaging portion to be arranged
Sealing；The outer diameter of input section is greater than the outer diameter of deferent segment, and therefore, the thrust that the pressure difference of inner cavity axial direction corresponding end surface is formed makes valve
Body axial movement；One of region between input section end and I end of sleeve and II end of deferent segment end and sleeve
Elastic element is set；Under the action of pressure difference and elastic force both direction potential energy, valve body makees axial reciprocating shifting relative to valve core tube
It is dynamic to realize opening and closing, power and energy.
The annular spool sealing surface is slope surface, can be unidirectional slope surface, two-way slope surface and arc slope, seals slope surface
The gradient is best >=and 8 degree, prevent ring-shaped valve seats and annular spool from locking phenomenon occur when being closely affixed.
Compressed spring is set between II end of sleeve and deferent segment end.
Extension spring is set between I end of sleeve and input section end.
The valve rod base that a piece valve rod is threaded through deferent segment end is set, and the round and smooth tail end of valve rod is coaxial successively to be withstood
Plate and compressed spring, compressed spring are fixed on II end of sleeve.
The valve core tube is axially perpendicular to ground, and deferent segment end suspends at least two compressed springs, compressed spring and sleeve
II end face of pipe is corresponding, contacts, offsets.
The spring, can be set in actual design and is adjusted axially function, achieve the purpose that be varied with pressure.
The engaging portion of the input section and sleeve I and deferent segment and sleeve II is respectively provided with sealing ring, input section and deferent segment
There is a land in end, and the inner end of land is embedded in lip ring.
The radial recirculation hole of the input section and the equal arrangement equal and well-balanced there are two aperture of deferent segment, in addition,
Input section side radially flows out interlayer again axially into interlayer there are two L-shaped small recirculation hole and inner cavity penetrates through.
The input section has the radial recirculation hole of at least two circles at least two well-balanced arrangements of every circle, and deferent segment also has corresponding
Well-balanced arrangement radial recirculation hole, total circulation area is less than the total circulation area of recirculation hole of input section, and both sides recirculation hole is equal
For the shrinkage cavity of three-level staged downbeam.
The interlayer is made of the intermediate pipeline section of the valve core tube of kernel and kernel radial radiation, can be it is integrated, can also
To be that kernel is axially forced to two parts of pipeline section among valve core tube and is constituted.
The bellows can be metal bellows, be also possible to the nonmetallic bellows such as plastics.
In conclusion asymmetric variation core pipe valve of the invention has the active effect that
1, structure is simple, convenient for manufacture；
2, no external leakage may be implemented in bellows seal；
3, ring packing valve seat and annular spool are axial straight contacts, few to rub, and sealing effect is good；
4, long service life, cost performance are high；
5, extraordinary operating condition is adapted to；
6, valve body is turned off formula to medium flow field as opening and closing element when closing valve, and opening and closing resistance is small；
Even if operability can be still good 7, under high-pressure medium state；
No matter 8, opening or closing, medium will not be to annular spool and ring-shaped valve seats erosion；
9, it relies on oneself non-return, adjusting, decompression and the current limliting of making a variation.
