Abstract
The invention discloses a novel packing, which comprises a packing body and is characterized in that the transverse section of the packing body is rectangular; one side of the packing body is provided with two elastic parts of which the transverse sections are triangular; the two elastic parts are arranged symmetrically by taking the midline of the transverse section of the packing body on one side where the two elastic parts are positioned as a symmetric axis; the first edges of the transverse sections of the elastic parts are coincided with the packing body; the second edges of the transverse sections of the elastic parts are close to the symmetric axis; the third edges of the transverse sections of the elastic parts are far away from the symmetric axis. The novel packing has the beneficial effects that the packing can be prevented from falling off after being inserted into an oblique sealing port by means of the close coincidence of the elastic parts, so that the air tightness of the packing is improved. Even if the elastic parts are worn, the packing body still has high air tightness.
Description
Technical field
The present invention relates to a kind of Sealing, be specifically related to a kind of novel packing.
Background technique
Packing is also named stuffing box packing, and packing seal is in leakage way, to stop liquid to flow leakage with fiber plug such as linen-cottons the earliest, is mainly used as the shaft seal of water lifting machinery.Because fill source is extensive, easy processing, cheap, sealing is reliable, simple to operate, so use till today.Nowadays packing is widely used in rotating shaft sealing, reciprocating pump, the reciprocal compressor of centrifugal pump, compressor, vacuum pump, stirrer and propeller for vessels, the to-and-fro motion shaft seal of refrigerator, and the turn sealing of various valve rods etc.
Existing packing is formed by more soft thread braiding conventionally, and sectional area is that square or rectangular, circular bar are filled in seal chamber conventionally, thereby realizes sealing.But the packing of this sectional area rule can not meet the sealing needs at the sealing position of cross section inclination, such packing easily wearing and tearing comes off, and causes sealability to reduce.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of packing of difficult drop-off.
In order to realize above-mentioned target, the present invention adopts following technological scheme:
Novel packing, comprise packing body, it is characterized in that, the cross section of above-mentioned packing body is rectangular, it is leg-of-mutton elastic component that one side of above-mentioned packing body is provided with two cross sections, and two above-mentioned elastic components are take the center line of the cross section of the packing body of a side at its place as symmetry axis symmetry; The Article 1 limit of above-mentioned elastic component cross section overlaps with packing body, and the Article 2 limit of above-mentioned elastic component cross section is near symmetry axis, and the Article 3 of above-mentioned elastic component cross section is outlying from symmetry axis.
Further, the elastic component that above-mentioned elastic component is acute triangle.
Further, the length on the Article 2 limit of above-mentioned elastic component is less than the length on the Article 3 limit of elastic component.
Further, two above-mentioned elastic components end points overlaps.
Further, above-mentioned packing body and two elastic components are integrally formed.
Further, above-mentioned packing body is the basic body of carbon fiber plate, and above-mentioned elastic component is carbon fiber elastic part.
Usefulness of the present invention is: by the difficult drop-off after the sealed mouth that coincidence can make packing insert to tilt of drawing close of elastic component, improved the sealing of packing.Even if the basic body of elastic component wear disc still has good sealability.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of the invention;
Fig. 2 is cross sectional representation embodiment illustrated in fig. 1;
Fig. 3 is the schematic diagram after elastic component embodiment illustrated in fig. 2 overlaps;
Fig. 4 is the cross sectional representation of another embodiment of the present invention.
The implication of reference character in figure:
1-packing body, 2-elastic component, a-Article 2 limit, b-Article 3 limit, the center line of the cross section of L-packing body.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
Novel packing as shown in Figure 1, Figure 2, Figure 3 shows, the cross section of packing body 1 is rectangular, it is 2, two elastic components 2 of leg-of-mutton elastic component take the center line L of the cross section of the packing body 1 of a side at its place as symmetry axis symmetry that one side of packing body 1 is provided with two cross sections; The Article 1 limit of elastic component cross section overlaps with packing body 1, and the Article 2 limit a(of elastic component 2 cross sections i.e. two limits that elastic component 2 is relative) near symmetry axis, the Article 3 limit b of elastic component 2 cross sections is away from symmetry axis.
As a kind of preferred version, packing body 1 and two the basic body of carbon fiber plate and carbon fiber elastic parts that elastic component 2 is one of the forming.
More than show and described basic principle of the present invention, major character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technological scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
