Abstract
The utility model relates to a sealing equipment field especially relates to a O type sealing washer with high sealed effect. The utility model provides a O type sealing washer with high sealed effect, this sealing washer is inside to be provided with the support frame, and the outside parcel of support frame has the rubber sleeve, this sealing washer inner ring fixedly connected with sheetmetal, and sheetmetal outer wall fixedly connected with silica gel pad. The supporting frame is arranged in the sealing ring, so that the situation that the sealing ring deforms due to overlarge pressure is reduced when the sealing ring is extruded by strength due to the supporting effect of the supporting frame, and meanwhile, the sealing performance of the sealing ring is improved by matching with the rubber sleeve wrapped outside; the metal sheet is arranged on the inner ring of the sealing ring, so that the stability of the whole sealing ring is improved, and the silica gel pad on the outer wall of the metal sheet enables the inner ring of the sealing ring to be in close contact with a sealed object, so that the sealing effect of the sealing ring is further enhanced. The utility model discloses good leakproofness has to stability is strong, and adaptability is better.
Description
Technical Field
The utility model relates to a sealing equipment field especially relates to a O type sealing washer with high sealed effect.
Background
The hardness of the existing O-shaped sealing ring can only be adjusted by replacing different rubber materials. The hardness and tensile strength (i.e. the tensile strength required for breaking the O-ring) of each type of rubber are determined, and the hardness and tensile strength of the O-ring thus produced are also determined, but the hardness and tensile strength of the O-ring cannot be increased in the prior art, and meanwhile, when the O-ring in the existing product is extruded by high strength, the O-ring deforms, thereby deteriorating the sealing performance.
Disclosure of Invention
In summary, in order to solve the problem that the sealing ring is deformed due to high-strength extrusion in the prior art, an O-shaped sealing ring with a high sealing effect is provided.
The utility model provides a O type sealing washer with high sealed effect, this sealing washer is inside to be provided with the support frame, and the outside parcel of support frame has the rubber sleeve, this sealing washer inner ring fixedly connected with sheetmetal, and sheetmetal outer wall fixedly connected with silica gel pad.
According to the arrangement, the support frame is arranged in the sealing ring, so that the situation that the sealing ring deforms due to overlarge pressure is reduced when the sealing ring is extruded by strength through the support effect of the support frame, and meanwhile, the sealing performance of the sealing ring is improved through the matching with the rubber sleeve wrapped outside; the metal sheet is arranged on the inner ring of the sealing ring, so that the stability of the whole sealing ring is improved, and the silica gel pad on the outer wall of the metal sheet enables the inner ring of the sealing ring to be in close contact with a sealed object, so that the sealing effect of the sealing ring is further enhanced.
The utility model discloses further set up, the support frame cross section is "worker" style of calligraphy.
The utility model discloses further set up, the outer anchor ring of sealing washer is provided with the recess.
Above-mentioned setting through set up the recess at the sealing washer outer annular surface, is to avoid damaging because of becoming the too big emergence of friction in the sealing washer use, leads to the condition appearance of sealed effect variation.
The utility model discloses further set up, support frame both ends outer wall shape is the arc.
Above-mentioned setting sets up to the arc because of support frame both ends outer wall, prevents that the sealing washer from receiving the extrusion in the use and can not be damaged by the support frame because of the sealing washer warp to influence the leakproofness.
The utility model discloses further set up, the sealing washer inner ring surface is provided with the recess.
The utility model discloses beneficial effect:
the O-shaped sealing ring has good sealing performance, strong stability, good adaptability and simple structure.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by the ordinary skilled person in the art without creative work all belong to the protection scope of the present invention.
As shown in fig. 1-2, the utility model relates to a O type sealing washer with high sealed effect, this sealing washer is inside to be provided with support frame 3, and 3 outside parcels of support frame have rubber sleeve 1, this sealing washer inner ring fixedly connected with sheetmetal 2, and 2 outer wall fixedly connected with silica gel pads 5 of sheetmetal.
1. Preferably, the cross section of the support frame 3 is I-shaped.
2. Preferably, the outer annular surface of the sealing ring is provided with a groove 4.
3. Preferably, the outer walls of the two ends of the support frame 3 are arc-shaped.
4. Preferably, the inner ring surface of the sealing ring is provided with a groove 4.
In-service use, this sealing washer is provided with "worker" style of calligraphy support frame 3 because of inside, and 3 outside parcels of support frame have rubber sleeve 1, make it can not appear the condition of excessive deformation in the use because of stress is too big, the leakproofness of this sealing washer in the use has been guaranteed, because 3 both ends outer wall shapes of support frame are the arc, prevent that the sealing washer from receiving the extrusion in the use and can not being harmd by support frame 3 because the sealing washer warp, influence the leakproofness of sealing washer, simultaneously sealing washer inner ring fixedly connected with sheetmetal 2, its outer wall fixedly connected with silica gel pad 5, the leakproofness of further reinforcing sealing washer closes stability, simultaneously the sealing washer inner ring all is provided with recess 4 with the outer loop.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims. While the invention has been described in detail and with reference to specific embodiments thereof, it will be apparent to one skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope thereof.
