Abstract
The utility model discloses a valve sealing element, include valve body, sealing member, compress tightly piece and centre bore, the valve body middle part is equipped with the valve rod, the valve rod passes the sealing member through the centre bore, the sealing member top is equipped with and compresses tightly the piece, the sealing member below is equipped with support piece, be equipped with the centre bore on the sealing member, the sealing member all is equipped with the flange on the face of centre bore both ends, the utility model discloses rational in infrastructure, the function is practical, owing to be equipped with the flange, during material such as transmission liquid, the flange is overlayed to the valve rod when the valve body in, and the leakproofness is better, and owing to compress tightly the piece, and the sealing member can not receive pressure and produce to move and lead to the fact the leakage, and this sealing member has that the leakproofness is good, dismantle conveniently and the valve rod reciprocates that the comparison is smooth and easy to reach steady advantage.
Description
Technical field
The utility model relates to field of mechanical technique, is specially a kind of valve sealing element.
Background technique
Valve generally comprises the pipeline that valve body is connected with valve body and the device closing and open pipeline.When valve rod opens valve, sealing must be had, material in no side valve door will leak, this just needs Sealing, but in the existing Sealing be applied on valve, the center bore inner wall of Sealing is generally only provided with a seal ring, and the shape of the cross section of its annular sealing ring is generally triangle, its Problems existing is: because only have an annular sealing ring, and valve rod, to move up and down stability in work bad, play phenomenon can occur.
The technological scheme that patent discloses a kind of Sealing of the patent No. 201120393304.0, although the sealing of ensure that, or could not solve valve rod moves up and down, and the problem of the upper and lower play of seal ring, causes valve rod to move up and down not steady.
Model utility content
The purpose of this utility model is to provide a kind of valve sealing element, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme: a kind of valve sealing element, comprise valve body, Sealing, compressing member and center hole, valve rod is provided with in the middle part of described valve body, described valve rod through Sealing by center hole, is provided with compressing member above described Sealing, is provided with supporting element below described Sealing, described Sealing is provided with center hole, and described Sealing is equipped with flange in center hole both ends of the surface.
Preferably, described flange and Sealing are integral type structure.
Preferably, described Sealing cross section is annular.
Preferably, described flange is that Sealing first extends outward to extend in center hole along center hole wall again and formed.
Compared with prior art, the beneficial effects of the utility model are: the utility model is rational in infrastructure, practical function, owing to being provided with flange, when materials such as fluid transfers in valve body, flange pressurized is affixed to valve rod, better tightness, and due to compressing member, Sealing can not be under pressure and produce and mobile cause leakage, this Sealing has good airproof performance, convenient disassembly and valve rod move up and down than smoothly and stable advantage.

Fig. 2 is the utility model schematic top plan view;
In figure: 1, valve body, 2, compressing member, 3, Sealing, 4, supporting element, 5, valve rod, 6, flange, 7, center hole.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model provides a kind of technological scheme: a kind of valve sealing element, comprise valve body 1, Sealing 3, compressing member 2 and center hole 7, valve rod 5 is provided with in the middle part of described valve body 1, described valve rod 5 through Sealing 3 by center hole 7, is provided with compressing member 2 above described Sealing 3, is provided with supporting element 4 below described Sealing 3, described Sealing 3 is provided with center hole 7, and described Sealing 3 is equipped with flange 6 in center hole 7 both ends of the surface.
Described flange 6 is integral type structure with Sealing 3, and described Sealing 3 cross section is annular, and described flange 6 is formed toward extension in center hole 7 toward extension along center hole 7 wall for Sealing 3 is first again.
Concrete usage mode: the utility model in use, valve rod 5 moves up and down, flange 6 on Sealing 3 receives the extruding of shipped material in valve body 1, flange 6 pressurized is affixed to valve rod 5 formation and is tightly connected, better tightness, and owing to being provided with compressing member 2, Sealing 3 can not be subject to valve internal pressure and move up and down, ensure that valve rod 5 moves up and down stably, simultaneously the good sealing effect of the seal.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any reference character in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to mode of execution, but not each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technological scheme in each embodiment also through appropriately combined, can form other mode of executions that it will be appreciated by those skilled in the art that.
