Abstract
The utility model discloses a kind of packing filling.The packing filling includes tubular body, and the inside and outside side at least one side of the tubular body is provided with double wedge, and the axis of the double wedge is set around the tubular body axis.So when above-mentioned packing filling is put into packing cavity, by gland to its axial pressure after, filler extrudes filler cavity wall and movement parts surface, due at double wedge material be more extruded after form local high density area, because high density area and low density area are arranged at intervals so as to artificially form a labyrinth channel.Contact area is reduced simultaneously because being contacted by double wedge with movement parts, reduces heat caused by friction so that above-mentioned packing filling can keep good trouble performance in a long time.
Description
Technical field
The utility model belongs to field of sealing technology, and in particular to a kind of packing filling.
Background technology
Packing filling is mainly used in the dynamic sealing of the process machine and equipment motion parts in machinery industry, for example centrifuges
The plunger or piston rod of pump, compressor, vavuum pump, mixer, the rotating shaft sealing of reactor and reciprocating pump, reciprocating compressor,
And do sealing between straight line, the valve rod of screw valve and fixed body.Packing_seal passes through bearing effect and labyrinth
Effect reaches good sealing effectiveness.But because packing_seal is typically to be used in dynamic sealing, therefore connect in packing and movement parts
Easily there is seepage in tactile surface.
Utility model content
For above technical problem, the utility model provides a kind of packing filling, and the packing filling includes tubulose master
Body, the inside and outside side at least one side of the tubular body are provided with double wedge, and the axis of the double wedge surrounds the tubular body axle
Line is set.
Preferably, it is equipped with the double wedge on the inside and outside side of the tubular body.
Preferably, the axis of the double wedge is into closed ring, and in the flat of the same vertical tubular body axis
In face, if double wedge described in arterial highway arranges along the tubular body axis.
If preferably, the double wedge of its axis in the plane of the same vertical tubular body axis is provided with
Dry breach, rectilinear direction of the breach along the parallel tubular body axis on adjacent two double wedge do not connect.
Compared with prior art, the utility model has the advantages that：The utility model discloses a kind of packing to fill out
Material, the packing filling include tubular body, and the inside and outside side at least one side of the tubular body is provided with double wedge, described convex
The axis of tooth is set around the tubular body axis.So when above-mentioned packing filling is put into packing cavity, by gland to its axle
To after pressure, filler extruding filler cavity wall and movement parts surface, due at double wedge material be more extruded after formed it is local highly dense
Area is spent, because high density area and low density area are arranged at intervals so as to artificially form a labyrinth channel.Simultaneously because pass through double wedge
Contacted with movement parts and reduce contact area, reduce heat caused by friction so that above-mentioned packing filling can be in a long time
Keep good trouble performance.

Fig. 1 is the complete section front view of the packing filling in the utility model the first embodiment.
Fig. 2 is the top view of the packing filling in the utility model the first embodiment.
Fig. 3 is the stereogram of the packing filling in second of embodiment of the utility model.
Fig. 4 is the complete section left view of the packing filling in second of embodiment of the utility model.
Embodiment
Below in conjunction with the accompanying drawings with embodiment, the utility model is further described.
Embodiment 1
As shown in Figure 1 and Figure 2, a kind of packing filling, the packing filling include tubular body, the tubular body it is interior,
Be equipped with double wedge 1 on lateral surface, the axis of the double wedge 1 is set around the tubular body axis, the axis of the double wedge 1 into
Closed ring, and in the plane in the same vertical tubular body axis, if double wedge 1 described in arterial highway is along the tubular body
Axis arranges.
Embodiment 2
It is second of embodiment of the utility model as shown in Figure 3, Figure 4, a kind of packing filling, the packing filling includes
Tubular body, double wedge 1 is equipped with the inside and outside side of the tubular body, the axis of the double wedge 1 surrounds the tubular body
Axis is set, and the axis of the double wedge 1 is in the plane of the same vertical tubular body axis, institute into closed ring
State double wedge 1 and be provided with some breach 2, the breach 2 on adjacent two double wedge 1 is along the straight of the parallel tubular body axis
Line direction does not connect.
Compared with prior art, the utility model has the advantages that：The utility model discloses a kind of packing to fill out
Material, the packing filling include tubular body, and the inside and outside side at least one side of the tubular body is provided with double wedge, described convex
The axis of tooth is set around the tubular body axis.So when above-mentioned packing filling is put into packing cavity, by gland to its axle
To after pressure, filler extruding filler cavity wall and movement parts surface, due at double wedge material be more extruded after formed it is local highly dense
Area is spent, because high density area and low density area are arranged at intervals so as to artificially form a labyrinth channel.Simultaneously because pass through double wedge
Contacted with movement parts and reduce contact area, reduce heat caused by friction so that above-mentioned packing filling can be in a long time
Keep good trouble performance.
The scope of protection of the utility model includes but is not limited to embodiment of above, and the scope of protection of the utility model is to weigh
Sharp claim is defined, and any replacement being readily apparent that to those skilled in the art that this technology is made, deformation, improvement are each fallen within
The scope of protection of the utility model.
