Abstract
The invention discloses a 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 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 member is and in particular to a kind of packing.
Background technology
Packing is also named airtight and watertight padding, and packing seal is to stop liquor stream to be let out in leakage path with fiber plug such as linen-cottons earliest
Leakage, is mainly used as the axle envelope of water lifting machinery.Due to fill source extensively, handling ease, cheap, sealed reliable, operation letter
Single, so using till today.Nowadays packing is widely used in turning of centrifugal pump, compressor, vacuum pump, blender and propeller for vessels
Turn sealing of sealing, piston pump, reciprocating compressor, the reciprocating motion axle envelope of refrigeration machine, and various valve rod etc..
Existing packing is generally formed by relatively soft thread braiding, and usual sectional area is square or rectangular, circle
Bar be filled in seal cavity, thus realize seal.But the packing of this sectional area rule can not meet section and incline
The sealing of oblique sealing position needs, and easily abrasion comes off such packing, causes sealing property to reduce.
Content of the invention
For solving the deficiencies in the prior art, it is an object of the invention to provide a kind of packing difficult for drop-off.
In order to realize above-mentioned target, the present invention adopts the following technical scheme that：
Packing, including packing body it is characterised in that the cross section of above-mentioned packing body is rectangle, above-mentioned packing is originally
The side of body is provided with the elastic component that two cross sections are triangle, the packing body of the side that two above-mentioned elastic components are located with it
Cross section center line be symmetrical axial symmetry；The a line of above-mentioned elastic component cross section is overlapped with packing body, above-mentioned elasticity
The Article 2 side of part cross section near axis of symmetry, the Article 3 of above-mentioned elastic component cross section outlying from axis of symmetry.
Further, above-mentioned elastic component is the elastic component of acute triangle.
Further, the Article 2 of above-mentioned elastic component while length be less than elastic component Article 3 while length.
Further, an end points of two above-mentioned elastic components 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.
The invention has benefit that：Overlapped so that packing inserts the seal of inclination by drawing close of elastic component
Difficult for drop-off afterwards, improve the sealing of packing.Even if the basic body of elastic component wear disc still has good sealing property.
Brief description
Fig. 1 is the structural representation of one embodiment of the invention；
Fig. 2 is the cross-sectional view of embodiment illustrated in fig. 1；
Fig. 3 is the schematic diagram after the elastic component coincidence of embodiment illustrated in fig. 2；
Fig. 4 is the cross-sectional view of another embodiment of the present invention.
The implication of in figure reference：
1- packing body, 2- elastic component, a- Article 2 side, b- Article 3 side, the center line of the cross section of L- packing body.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is made with specific introduction.
Packing as shown in Figure 1, Figure 2, Figure 3 shows, the cross section of packing body 1 is rectangle, and the side of packing body 1 is provided with
Two cross sections are the elastic component 2 of triangle, in the cross section of packing body 1 of side that two elastic components 2 are located with it
Line L is symmetrical axial symmetry；The a line of elastic component cross section is overlapped with packing body 1, the Article 2 side of elastic component 2 cross section
, near axis of symmetry, the Article 3 side b of elastic component 2 cross section is away from axis of symmetry for a (i.e. the relative side of two elastic components 2).
Elastic component 2 is elastic component that cross section is acute triangle.The length of the Article 2 side a of elastic component is less than elastic component
Article 3 side b length, be so easy to two elastic components 2 and draw close to axis of symmetry.Two elastic components 2 after the overlap that is squeezed
Cross section be merged into a big triangle, simultaneously elastic component 2 itself be subject to Article 3 side b outwards separate pulling force, therefore
This big triangle can be stuck in the sealing position of inclination, it is possible to increase sealing property.After elastic component 2 weares and teares, elastic component 2
The pulling force of Article 3 side b can be subject to outwards separately, remain able to fill up sealing position.The one of a line of two elastic components 2
Individual end points overlaps, and that is, two elastic components 2 have a common summit, and the relative side of the elastic component 2 after being so squeezed is permissible
It is completely superposed.As Fig. 4, in order that the even closer coincidence of the Article 2 side a of elastic component 2, the Article 2 side a of elastic component 2 is permissible
It is the toothed edge that cooperates.Now, air line distance between the two-end-point of a for the Article 2 is less than length during Article 3.
As a kind of preferred version, the basic body of carbon fiber plate and carbon that packing body 1 and two elastic components 2 are one of the forming
Fibrous elasticity part.
The basic principles, principal features and advantages of the present invention have been shown and described above.The technical staff of the industry should
Understand, the invention is not limited in any way for above-described embodiment, all obtained by the way of equivalent or equivalent transformation
Technical scheme, all falls within protection scope of the present invention.
