Abstract
The utility model discloses a kind of valve element groove structure, and it includes valve element and a plurality of grooves being circumferentially located at from top to bottom along valve element on valve core outer surface.The utility model can effectively reduce the contact area of valve element and sleeve with avoid because friction and caused by stucking phenomena, moreover it is possible to reduce pipeline small particles impurity to covering the damage of sealing surface of seat.
Description
Technical field
It the utility model is related to valve field, and in particular to a kind of valve element groove structure.
Background technology
It is shown in Figure 1, valve rod 3, valve element 1 and sleeve 4 are provided with valve body 5, valve element is located at valve stem end, existing valve element
Radial dimension is identical, and the contact area of valve element and sleeve is big, and in use, the little particle impurity in pipeline readily flows to cover
Cylinder in valve turn-off transient with the gap location and sealing surface of seat of valve element, can not only be such that valve element generation stucking phenomena also presses
Bad sealing surface makes occur pit on sealing surface, causes leakage so as to cause valve to be unable to completely close.
The content of the invention
Goal of the invention of the present utility model is to provide a kind of valve element groove structure, can effectively reduce connecing for valve element and sleeve
Contacting surface product with avoid because friction and caused by stucking phenomena, moreover it is possible to reduce pipeline small particles impurity to cover sealing surface of seat damage
It is bad.
To achieve the above object of the invention, the technical solution adopted in the utility model is：A kind of valve element groove structure, it includes
Valve element and a plurality of grooves being circumferentially located at from top to bottom along valve element on valve core outer surface.
Preferably, the groove is end to end annular ditch groove.
Preferably, the rectangular cross-section of the groove.
Further, the quantity of the groove is 6 ~ 8.Preferably, the quantity of the groove is 7.
Preferably, the spacing between each two adjacent trenches is equal.
Further, the width of the groove is 2 ~ 4mm, and depth is 2 ~ 4mm.Preferably, the width of the groove is
2mm, depth 2mm.
Further, the size all same or incomplete same of each groove.
Because above-mentioned technical proposal is used, the utility model has following advantages compared with prior art：
1. the utility model is on the outer surface of valve element by setting a plurality of grooves, the little particle impurity in pipeline can be with
Flow in groove, can effectively prevent little particle impurity from flowing at the gap location and sealing surface of seat of sleeve and valve element, so as to
Reduce the contact area of valve element and sleeve with avoid because friction and caused by stucking phenomena, and reduce pipeline small particles impurity pair
The damage of sealing surface of seat is covered, extends the service life of valve, the impurity in groove can be cleaned in maintenance of valve；
2. the utility model is simple in construction, easily manufactured, bad working environments demand is disclosure satisfy that, suitable for popularization and application.
Brief description of the drawings
Fig. 1 is the valve core structure schematic diagram of prior art.
Fig. 2 is the valve core structure schematic diagram of the utility model embodiment one.
Wherein：1st, valve element；2nd, groove；3rd, valve rod；4th, sleeve；5th, valve body.
Embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model：
Embodiment one：
Shown in Figure 2, a kind of valve element groove structure, it includes valve element 1 and is circumferentially located at valve along valve element from top to bottom
A plurality of grooves 2 on core outer surface, the groove are formed by lathe process.
In the present embodiment, the valve element is located in sleeve 4 and is engaged with sleeve, and the valve element is connected with valve rod 3, described
Valve element, valve rod and sleeve are located in valve body 5.
The groove is end to end annular ditch groove.
The rectangular cross-section of the groove.
The quantity of the groove is 7.
Spacing between each two adjacent trenches is equal.
The width of the groove is 2mm, depth 2mm.
The size all same or incomplete same of each groove, only need to meet that little particle impurity can be flowed into groove
.
The little particle impurity that groove of the present utility model can allow in pipeline flows into wherein, prevents little particle impurity from flowing to set
Cylinder with the gap location and sealing surface of seat of valve element, so as to reduce the contact area of valve element and sleeve, in valve turn-off transient
Be not in stucking phenomena, and reduce damage of the pipeline small particles impurity to set sealing surface of seat, extend valve uses the longevity
Order, the impurity in groove can be cleaned in maintenance of valve.
The foregoing description of the disclosed embodiments, professional and technical personnel in the field are enable to realize or new using this practicality
Type.A variety of modifications to above-described embodiment will be apparent for those skilled in the art, determine herein
The General Principle of justice can be realized in other embodiments in the case where not departing from spirit or scope of the present utility model.Cause
This, the utility model is not intended to be limited to above-described embodiment shown in this article, and is to fit to and principles disclosed herein
The most wide scope consistent with features of novelty.
