For achieving the above object, technical solution adopted in the utility model is: providing a kind of sleeve adjusting valve core assembly, including flap and valve seat, flap upper end is provided with valve rod, and flap lower end is positioned at inside valve seat；Flap is provided with and the sealing surface of valve seat opening laminating, and flap lower end is provided with the positioning guide column being positioned within valve seat, is provided with the through flow hole at multiple through flap two ends inside flap upper end, and sealing surface narrows towards positioning guide column direction；Positioning guide column is provided with the annular groove for avoiding affecting discharge characteristic and some grooves, and institute is fluted uniformly to arrange around positioning guide column external cylindrical surface, annular groove coaxial with flap and with fluted UNICOM, annular groove is between groove and sealing surface.
As preferably, on flap, Middle face is provided with the blind hole of indent, and valve rod lower end is provided with the locking cap being positioned at blind hole, and valve rod lower end is socketed with the sleeve for being fixed in blind hole by locking cap, and sleeve is spirally connected with blind hole.
As preferably, flap upper end is from top to bottom sequentially provided with step I and step II, and step II is socketed with flexible gasket ring, step I is socketed with and the pressure ring of flexible gasket ring laminating.
As preferably, pressure ring is fixed on flap by trip bolt, and trip bolt is spirally connected through pressure ring with flap.
The beneficial effects of the utility model are:
1, the sealing surface of flap of the present utility model seals laminating with valve seat opening part, and positioning guide column is inserted in valve seat positioned internal can make the sealing surface of flap be easier to align with valve seat, it can be ensured that the sealing of regulation valve is more good reliable；Positioning guide column is evenly equipped with some grooves along cylindrical, and groove connects matching trim and can ensure that positioning guide column does not affect the discharge characteristic of regulation valve with annular groove.
2, valve rod of the present utility model realizes floating connection by sleeve and flap, it can be ensured that the deformation of valve rod does not interferes with the sealing surface of flap and the sealing of valve seat, regulation valve can be made to seal relatively reliable, so that regulation valve is longer for service life.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with this utility model specific embodiment and corresponding accompanying drawing, technical solutions of the utility model are clearly and completely described.
With reference to Fig. 1,2,3, the present embodiment provides a kind of sleeve adjusting valve core assembly, and including flap 4 and valve seat 10, flap 4 upper end is provided with valve rod 8, and it is internal that flap 4 lower end is positioned at valve seat 10.Flap 4 is provided with and the sealing surface 3 of valve seat 10 opening laminating, and flap 4 lower end is provided with the positioning guide column 1 being positioned within valve seat 10, is provided with the through flow hole 5 at multiple through flap 4 two ends inside flap 4 upper end, and sealing surface 3 narrows towards positioning guide column 1 direction.Positioning guide column 1 is provided with the annular groove 2 for avoiding affecting discharge characteristic and some grooves 9, and institute fluted 9 uniformly arranges around positioning guide column 1 external cylindrical surface, annular groove 2 coaxial with flap 4 and with fluted 9 UNICOMs, annular groove 2 is between groove 9 and sealing surface 3.
On flap 4, Middle face is provided with the blind hole 14 of indent, and valve rod 8 lower end is provided with the locking cap 13 being positioned at blind hole 14, and valve rod 8 lower end is socketed with the sleeve 12 for being fixed in blind hole 14 by locking cap 13, and sleeve 12 is spirally connected with blind hole 14.
Flap 4 upper end is from top to bottom sequentially provided with step I 15 and step II 16, and step II 16 is socketed with flexible gasket ring 6, step I 15 is socketed with and the pressure ring 7 of flexible gasket ring 6 laminating.Pressure ring 7 is fixed on flap 4 by trip bolt 11, and trip bolt 11 is spirally connected through pressure ring 7 with flap 4.
In implementation process, positioning guide column 1 cylindrical is formed when regulating valve and closing with valve seat 10 endoporus and coordinates, the sealing surface 3 of flap 4 seals laminating with valve seat 10 opening part, positioning guide column 1 is inserted in valve seat 10 positioned internal can make the sealing surface 3 of flap 4 be easier to align with valve seat 10, it can be ensured that the sealing of regulation valve is more good reliable.Positioning guide column 1 is evenly equipped with some grooves 9 along cylindrical, and groove 9 connects matching trim 3 and can ensure that positioning guide column 1 does not affect the discharge characteristic of regulation valve with annular groove 2.
With reference to Fig. 2, when using the valve rod 8 of thick and good rigidity, valve rod 8 can form a fixed connection with flap 4, makes whole core assembly reach the highest axiality, is conducive to improving the sealing property of regulation valve.With reference to Fig. 3, when the valve rod 8 that employing is tiny and rigidity is little, valve rod 8 realizes floating connection by sleeve 12 and flap 4, can ensure that the deformation of valve rod 8 does not interferes with the sealing surface 3 of flap 4 and the sealing of valve seat 10, balance valve core structure regulation valve operating physical force can be made less, regulation valve can be made to seal relatively reliable, so that regulation valve is longer for service life.
Above-mentioned embodiment is used for illustrating this utility model; rather than this utility model is limited; in spirit of the present utility model and scope of the claims, any modifications and changes that this utility model is made, both fall within protection domain of the present utility model.
