Abstract
The invention relates to the technical field of industrial parts, in particular to an improved sealing piece. The improved sealing piece comprises a body and a center hole formed in the body. The body is provided with at least two arc-shaped holes communicated with the center hole in the horizontal direction, and arc-shaped plates are matched to be inserted in the arc-shaped holes. One ends of the arc-shaped plates penetrates out of the arc-shaped holes and are covered with rubber layers, and push-pull pieces are integrally formed at the other ends of the arc-shaped plates. According to the improved sealing piece, the arc-shaped holes are formed in the body, the arc-shaped plates are matched to be arranged in the arc-shaped holes, in the using process, the arc-shaped plates are pushed to be in contact with a valve rod, and therefore moving of the valve rod is controlled. In addition, one ends of the arc-shaped plates are provided with the rubber layers which can achieve a better sealing effect together with the body.
Description
Technical field
The present invention relates to industrial part technical field, especially relate to the sealing member of a kind of improvement.
Background technology
In the existing sealing member being applied on valve, the center bore inner wall of sealing member is typically provided only with a ring packing
Ring, and the shape of its annular sealing ring cross section is generally triangle, due to only one of which annular sealing ring, so valve rod is upper
Move down disorder of internal organs less stable, it may occur that the phenomenon of play.
Utility model content
The deficiency existed for above-mentioned prior art, the purpose of this utility model is to provide the sealing member of a kind of improvement, its
Have the advantages that sealing effectiveness is more preferable and valve rod is more stable in movement.
To achieve these goals, this utility model be the technical scheme is that the sealing member of a kind of improvement, including this
Body and the centre bore being opened in body central, described body laterally offers at least two arcuate sockets communicated with centre bore, should
Coordinating in arcuate socket and be inserted with arc, one end of arc passes arcuate socket and this end is coated with rubber layer, arc another
One end is integrally formed with push-pull piece.
Wherein, described inner body wall is arranged with dismountable packing ring, and described packing ring offers is easy to the logical of arc insertion
Hole, the through-hole wall of packing ring is extended with stator.
Wherein, described body laterally offers at least two threaded hole communicated with centre bore, and this threaded hole is described arc
The further restriction in shape hole, coordinates in this threaded hole and is inserted with spiral lamina, and this spiral lamina is the further restriction of described arc.
Use after said structure, this utility model the most advantageously: it includes body and opens
Being located at the centre bore of body central, described body laterally offers at least two arcuate sockets communicated with centre bore, this arcuate socket
Interior cooperation is inserted with arc, and one end of arc passes arcuate socket and this end is coated with rubber layer, the other end one of arc
Body formed have push-pull piece, and this utility model is by offering arcuate socket at body, and in arcuate socket, cooperation is provided with arc, makes
Used time, by promoting arc, making arc conflict with valve rod, control the play of valve rod with this, additionally arc one end is provided with
Rubber layer can play better seal effect together with body.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
In figure: 1, body；2, centre bore；
3, arcuate socket；4, arc；
5, push-pull piece.
Detailed description of the invention
The following stated is only preferred embodiment of the present utility model, the most therefore limits protection model of the present utility model
Enclose.
As shown in Figure 1: the sealing member of a kind of improvement, including body 1 and the centre bore 2 that is opened in body 1 center, described
Body 1 laterally offers at least two arcuate sockets 3 communicated with centre bore 2, coordinates and be inserted with arc 4, arc in this arcuate socket 3
One end of plate 4 passes arcuate socket 3 and this end is coated with rubber layer, and the other end of arc 4 is integrally formed with push-pull piece 5, described
Body 1 can also be provided with dismountable packing ring at inner wall sleeve, and described packing ring offers is easy to the through hole that arc 4 inserts, packing ring
Through-hole wall be extended with stator, described body 1 also can laterally offer at least two threaded hole communicated with centre bore, should
Coordinating in threaded hole and be inserted with spiral lamina, this utility model is by offering arcuate socket 3 at body 1, and coordinates in arcuate socket 3 and set
There is arc 4, in use, by promoting arc 4, make arc 4 conflict with valve rod, control the play of valve rod with this, separately
Outer arcuate plate one end is provided with rubber layer can play better seal effect together with body.
The above is only better embodiment of the present utility model, therefore all according to described in this utility model patent claim
Structure, feature and principle done equivalence change or modify, be all included in this utility model patent claim.
