Abstract
The utility model discloses a kind of double containment antiseize valve core structures, including upper valve base, the sealing of upper valve base inclined-plane, sealed valve stem groove, lower peripheral surface sealed valve stem, floating seal wound gasket and bottom sealing socket between two-seater, it is characterized in that, lower peripheral surface sealed valve stem is equipped in the upper valve base, lower peripheral surface sealed valve stem bottom end is equipped with sealing spherical surface, the lower peripheral surface sealed valve stem is sealed equipped with upper valve base inclined-plane, upper valve base inclined-plane sealing downside is equipped with sealed valve stem groove, the upper valve base bottom end is equipped with bottom sealing socket, equipped with floating seal wound gasket between two-seater between the upper valve base and bottom sealing socket.The utility model seals the floating seal wound gasket between two-seater by upper valve base inclined-plane and realizes double containment, increase the tightness of sealing, by sealed valve stem groove, the impurity of fluid scouring can be stored in this groove, without being attached to valve rod, on valve seat, the tightness of sealing is increased.
Description
Technical field
The utility model relates to a kind of spool, specifically a kind of double containment antiseize valve core structure.
Background technique
Spool be valve body realized by its movement direction controlling, pressure control or flow control basic function valve
Part is divided into rotary (45 °, 90 °, 180 °, 360 °), parallel-moving type (radial, towards) by move mode.It can divide by shape
It (is changed for spherical (ball valve), conical (cock), patty (butterfly valve and gate valve), dome type (shut-off valve and check-valves) cylinder
To valve).Generally based on bronze or stainless steel, also there are plastics, nylon, ceramics, glass etc..Pervious valve base sealing structure is all
Single sealing, spool pass through fluid scouring, can be attached on valve rod with some impurity, cause spool that cannot close.
Utility model content
The purpose of this utility model is to provide a kind of double containment antiseize valve core structures, to solve in above-mentioned background technique
The problem of proposition.
To achieve the above object, the utility model provides the following technical solutions:
A kind of double containment antiseize valve core structure, including the sealing of upper valve base, upper valve base inclined-plane, sealed valve stem groove, lower ball
Floating seal wound gasket and bottom sealing socket between face sealed valve stem, two-seater, which is characterized in that it is close that lower peripheral surface is equipped in the upper valve base
Valve rod is sealed, the lower peripheral surface sealed valve stem is sealed equipped with upper valve base inclined-plane, and upper valve base inclined-plane sealing downside is equipped with sealing
Stem groove, the upper valve base bottom end are equipped with bottom sealing socket, close equipped with floating between two-seater between the upper valve base and bottom sealing socket
Seal wound gasket.
As a further solution of the present invention: lower peripheral surface sealed valve stem bottom end is equipped with sealing spherical surface.
Compared with prior art, the utility model has the beneficial effects that the utility model by upper valve base inclined-plane sealing with
Between two-seater floating seal wound gasket realize double containment, increase the tightness of sealing, by sealed valve stem groove, fluid scouring it is miscellaneous
Matter can be stored in this groove, without being attached to valve rod, on valve seat, increase the tightness of sealing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of double containment antiseize valve core structure.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole

Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, in the utility model embodiment, a kind of double containment antiseize valve core structure, including upper valve base 1, on
Floating seal wound gasket 5 and bottom sealing socket 6 between valve seat inclined-plane sealing 2, sealed valve stem groove 3, lower peripheral surface sealed valve stem 4, two-seater,
Lower peripheral surface sealed valve stem 4 is equipped in the upper valve base 1, the lower peripheral surface sealed valve stem 4 is equipped with upper valve base inclined-plane sealing 2, institute
It states 2 downside of upper valve base inclined-plane sealing and is equipped with sealed valve stem groove 3, the impurity of fluid scouring can be stored in this groove, without
It is attached to valve rod, on valve seat, increases the tightness of sealing, 4 bottom end of lower peripheral surface sealed valve stem is equipped with sealing spherical surface, institute
1 bottom end of upper valve base is stated equipped with bottom sealing socket 6, floating seal wound gasket between two-seater is equipped between the upper valve base 1 and bottom sealing socket 6
5。
When the utility model is used, by upper valve base inclined-plane sealing 2 and upper valve base 1 between seal and upper valve base 1 and under it is close
Floating seal wound gasket 5 realizes double containment between sealing the two-seater between seat 6, increases the tightness of sealing, passes through sealed valve stem groove
3, the impurity of fluid scouring can be stored in this groove, without being attached to valve rod, on valve seat, increase the tight of sealing
Property.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new

All changes in justice and range are embraced therein.It should not treat any reference in the claims as limiting
Related claim.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
The other embodiments being understood that.
