Abstract
The invention discloses a trapezoidal slip-ring-type combination sealing ring, and belongs to the manufacturing field of combination sealing materials. The trapezoidal slip-ring-type combination sealing ring comprises a trapezoidal sealing ring and an O-shaped rubber ring, wherein a triangular groove is formed in the right sealing surface of the trapezoidal sealing ring; a circular arc groove is formed in the lower lip surface of the trapezoidal sealing ring; the trapezoidal sealing ring is made of polytetrafluoroethylene; the O-shaped rubber ring is made of nitrile rubber; and the section of the O-shaped rubber ring is circular. The trapezoidal slip-ring-type combination sealing ring has such advantages as simple structure, convenience for mounting, good sealing performance, little frictional force, long service life and automatic elastic compensation, and is particularly suitable for high-speed rotary sealing.
Description
Technical field
The invention belongs to combined labyrinth and carbon gland material and manufacture field, relate in particular to a kind of trapezoidal sliding ring combined seal.
Background technique
Sealing is to prevent that fluid or solid particle from, from leaking between adjacent junction plane and preventing the component that introduced contaminants is invaded machinery equipment inside as dust and moisture etc., having static seal and the large class of motive sealing two.Static seal mainly contains pad sealing, sealant sealing and directly contacts sealing three major types; Motive sealing can be divided into rotary seal and two kinds of fundamental types of reciprocation sealing, and whether the component of doing relative movement by Sealing and its contact, and can be divided into contact seal and noncontact seal; Can be divided into again circumferential sealing and end face seal by Sealing and contact position.To the basic demand of sealing be good airproof performance, safe and reliable, life-span length, compact structure, system simply, manufacture easy to maintenance, with low costly, most of Sealing easily damaged partss, should ensure interchangeability, realize standardization, seriation.Requirement to sealing material is: material compactness is good; There are suitable mechanical strength and hardness; Compressibility and rebound elasticity are good; Not softening under high temperature, non-sclerous under low temperature; Corrosion resistance is good; Friction factor is little, and wear resistance is good; Have with sealing surface and paste full ductility; Ageing resistance is good; Low price.Can select as required the materials such as rubber, graphite tape, teflon to make.The present invention is a kind of trapezoidal sliding ring combined seal, belongs to rotation, contact-type circumferential sealing in motive sealing.Sealing circle is the garden ring of a similar trapezoidal sliding ring of sectional shape and an O shape rubber body composition, sliding ring adopts the composite material that teflon is main raw material to make, because of teflon friction factor little, be only 0.02-0.04, having self-lubricating property and static and dynamic friction coefficient equates, thermal adaptability is strong, and advantage that can long-term work within the scope of-55-255 DEG C, for the normal work of sliding ring provides guarantee.The right of trapezoidal seal ring is provided with triangular groove, and triangular groove makes to contact and diminish with dual face, and the frictional force of generation is little and heat-dissipating is less, can store lubricant oil in triangular groove simultaneously, has further strengthened sealing effect, has reduced frictional force, the thin lip in lower end of trapezoidal seal ring is provided with a groove, O shape rubber ring is placed in groove, the surface of contact of O shape rubber ring and groove is circular arc, O shape rubber ring has pre compressed magnitude after being combined with groove and installing, there is certain precompressed O shape rubber ring to pre-pressing force of trapezoidal seal ring, trapezoidal seal ring is tightly fitted in by Sealing surface, faying surface has the effect of lubricating and playing sealing without leakage, along with the increase of sealing directional pressure, the enclasping force of sealing is larger, the laminating on sealed surface is tightr, be that more high leak tightness is better for pressure, therefore, trapezoidal combination seal has good selfsealings performance, O shape rubber ring by two side bumpers of trapezoidal seal ring, thereby can " do not extruded ", can tolerate the pressure of 300Mpa, when the polytetrafluoroethylene ring long-term work of high abrasion forms after wearing and tearing, the spring energy that O shape rubber ring provides makes seal ring produce enough distortion with compensate for wear amount, therefore trapezoidal combination seal has the function of auto-compensation, greatly improve operating life.Due to the combination of teflon seal ring and O shape rubber ring, make the features such as trapezoidal combined seal ring has long working life, and surface friction drag is little, and sealability is splendid, anti-high pressure.
Summary of the invention
The problem that the present invention mainly solves is to provide a kind of trapezoidal sliding ring combined seal, the series of advantages such as that this product has is simple in structure, easy for installation, good seal performance, frictional force are little, long working life, automatic elastic compensating.
The technical solution used in the present invention is:
A kind of trapezoidal sliding ring combined seal, comprising: trapezoidal seal ring, O shape rubber ring; It is characterized in that: the right sealing surface of trapezoidal seal ring is provided with triangular groove, the lower labial surface of trapezoidal seal ring is provided with circular groove.
Further technological scheme of the present invention is:
Described trapezoidal seal ring is made up of teflon.
Described O shape rubber ring is made up of nitrile butadiene rubber, and its cross section is circular.
The invention has the beneficial effects as follows: a kind of trapezoidal sliding ring combined seal is provided, the advantage of this trapezoidal sliding ring combined seal is: simple in structure, easy for installation, good seal performance, frictional force are little, long working life and have the advantages such as automatic elastic compensating, are especially adapted to High Rotation Speed sealing.
Brief description of the drawings:
If Fig. 1 is sectional view of the present invention, Fig. 2 is trapezoidal sliding ring combined seal entirety plan view.
Embodiment
Further illustrate the particular content that uses this trapezoidal sliding ring combined seal most preferred embodiment below in conjunction with accompanying drawing:
1. a trapezoidal sliding ring combined seal, comprising: trapezoidal seal ring 1, O shape rubber ring 2; It is characterized in that: the right sealing surface of trapezoidal seal ring is provided with triangular groove 101, the lower labial surface of trapezoidal seal ring is provided with circular groove 102; Described trapezoidal seal ring 1 is made up of teflon; Described O shape rubber ring 2 is made up of nitrile butadiene rubber, and its sectional shape is circular.
3. by after this combined seal ring installation, the right of trapezoidal seal ring 1 is provided with triangular groove 101, when use, the interior storage lubricant oil of triangular groove 101 plays lubrication and seal effect, the thin lip in lower end of trapezoidal seal ring 1 is provided with circular groove 102, O shape rubber ring 2 is placed in circular groove 102, O shape rubber ring 2 has pre compressed magnitude with circular groove 102 after installing, trapezoidal seal ring 1 is tightly fitted in by the surface of Sealing, faying surface has the lubricated effect that plays sealing without leaking, along with the increase of sealing directional pressure, the enclasping force of sealing is larger, the laminating on sealed surface is tightr, be that more high leak tightness is better for pressure, O shape rubber ring 2 by 102 liang of side bumpers of the circular groove of trapezoidal seal ring 1, thereby can " do not extruded ", can tolerate the pressure of 300Mpa, when trapezoidal seal ring 1 long-term work of high abrasion forms after wearing and tearing, the spring energy that O shape rubber ring 2 provides makes trapezoidal seal ring 1 produce enough distortion with compensate for wear amount, therefore trapezoidal combined seal ring has the function of auto-compensation, greatly improve the operating life of trapezoidal combined seal ring.
