Description
Technical Field
The utility model relates to a sealing part field, concretely relates to novel combined seal circle.
Background
When sealing up between the part, current sealing part generally chooses O type circle for use, but because O type circle damage easily, need often change it, in the assembling process, O type circle commonly used is extruded in following the seal groove easily, leads to the installation failure, and the installation failure back, O type circle is damaged by the extrusion easily, leads to unable reuse, consequently needs a sealing performance good, long service life, the combination sealing washer of the installation of being convenient for.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a simple structure, simple to operate, sealing performance is good, can carry out effectual protection to O type circle, can increase the extrusion force of O type circle to sealed face after the installation to increase the novel combined seal circle of sealing performance.
In order to realize the purpose, the utility model provides a technical scheme is:
the utility model provides a novel combined seal ring, includes the support ring, the terminal surface all is fixed with rather than endocentric guide ring about the support ring, and the terminal surface that two guide rings carried on the back mutually is the inclined plane, the inclined plane inclines to support ring center direction towards the one end in support ring axle center, and outer annular groove has been seted up to the support ring outer fringe, and the inner ring groove has been seted up to the support ring inner edge, installs outer O type circle and interior O type circle in outer annular groove and the inner ring groove respectively.
Specifically, arc-shaped grooves are formed in the upper side and the lower side of the groove wall of the outer ring groove, flanges are machined in the upper side and the lower side of the outer O-shaped ring, and the flanges are located in the arc-shaped grooves on one side of the outer O-shaped ring.
Specifically, the outer O-shaped ring and the inner O-shaped ring are made of nitrile rubber.
Specifically, the support ring and the guide ring are integrally formed.
Specifically, the support ring and the guide ring are made of polyurethane materials.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses, simple structure, simple to operate, sealing performance is good, can carry out effectual protection to O type circle, can prevent that the sealing washer from breaking away from in the installation, can increase the extrusion force of O type circle to sealed face after the installation to sealing performance has been increased.

Detailed Description
As shown in figures 1-2, a novel combined sealing ring comprises a supporting ring 1, guide rings 2 concentric with the supporting ring 1 are fixed on the upper and lower end faces of the supporting ring 1, the support ring 1 and the guide ring 2 are integrally formed, the support ring 1 and the guide ring 2 are made of polyurethane materials, the end surfaces of the two guide rings 2 which are opposite to each other are inclined surfaces, one end of the inclined plane facing the axis of the support ring 1 inclines towards the center of the support ring 1, the outer edge of the support ring 1 is provided with an outer ring groove 6, the inner edge of the support ring 1 is provided with an inner ring groove 7, an outer O-shaped ring 3 and an inner O-shaped ring 8 are respectively arranged in the outer ring groove 6 and the inner ring groove 7, outer O type circle 3 and interior O type circle 8 are the butadiene acrylonitrile rubber material, arc recess 4 has all been seted up to the upper and lower both sides of 6 cell walls of outer annular groove, and flange 5 has all been processed to the upper and lower both sides of outer O type circle 3, and flange 5 is located the arc recess 4 of its one side.
When the utility model is installed, the outer O-shaped ring 3 and the inner O-shaped ring 8 are respectively installed in the outer ring groove 6 and the inner ring groove 7, and the flange 5 of the outer O-shaped ring 3 is positioned in the arc groove 4 on one side, when the utility model is installed, the combined sealing ring is sleeved on the shaft after being expanded, then the combined sealing ring is moved to the sealing groove, under the elastic action of the supporting ring 1, the combined sealing ring can retract into the sealing groove, in the process of retracting the combined sealing ring into the sealing groove, the guiding action of the inclined plane of the guiding ring 2 is small, the supporting ring 1 is compressed by extrusion, at the moment, the inner O-shaped ring 8 and the outer O-shaped ring 3 are extruded and deformed, the inner O-shaped ring 8 expands towards the inner direction of the supporting ring 1, the inner O-shaped ring 8 is tightly abutted against the groove bottom of the sealing groove, the outer O-shaped ring 3 expands towards the outer side of the supporting ring 1, thereby the outer O-shaped ring 3 can increase the pressure to the sealing surface, through the internal O-shaped ring 8 and the external O-shaped ring 3 which are extruded and deformed, the combined sealing ring is expanded, so that the whole diameter of the combined sealing ring is increased after the combined sealing ring is positioned in the sealing groove, and the better sealing performance can be guaranteed. Through the cooperation of arc recess 4 and flange 5, support ring 1 is by the extrusion compression back, can increase the stability of outer O type circle 3 in outer annular 6, easy to assemble.
The utility model discloses, simple structure, simple to operate, sealing performance is good, can carry out effectual protection to interior O type circle 8 and outer O type circle 3, can prevent that interior O type circle 8 and outer O type circle 3 from breaking away from in the installation, can increase the extrusion force of O type circle to sealed face after the installation to holistic sealing performance has been increased.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
