Abstract
The utility model provides a metal skeleton seal ring. The metal skeleton seal ring solves the problem that the seal ring intensity is low, the seal ring is easily corroded by the liquid and gas, and the seal ring is easily distorte in existing sealing ring. The metal skeleton seal ring is characterized in that a metal skeleton is arranged in the rubber body (1). The utility model has the advantages that the intensity of the metal skeleton seal ring is high, the metal skeleton seal ring does not corrode by the liquid and gas easily, and the distortion does not generate easily.
Description
Technical field:
The utility model relates to downhole tool field, oil field used seal fitting, especially metal frame seal ring.
Background technique:
On the down-hole oil production tools structure of oil field, need the seal ring sealing between a lot of parts.At present the seal ring that adopts generally all is to be made by rubber, because intensity is low, bad or produce distortion by highly pressurised liquid or gas thorn easily when liquid or gas pressure are high, making seal failure between the parts increases maintenance load, influences ordinary production.
The model utility content:
For overcome existing seal ring intensity low, easily by the deficiency of liquid or bad, the easy generation distortion of gas thorn, the utility model provides a kind of metal frame seal ring, the sealing circle has the intensity height, it is bad by liquid or gas thorn to be difficult for, be difficult for producing the characteristics of distortion.
The invention for solving the technical problem can reach by following technical solution: this metal frame seal ring comprises rubber body, and rubber body is built-in with metal frame.
Above-mentioned metal is a steel wire; The outer vulcanized rubber of steel wire and being integral.
The utility model is compared with background technique has following beneficial effect: owing to the metal frame seal ring is integral by rubber and the sulfuration of metal steel wire, intensity of steel wire height in making, the outer rubber good springiness, when liquid or gas pressure are high, be difficult for by liquid or gas thorn bad, and be difficult for the generation distortion, so this metal frame seal ring has the intensity height, is difficult for by liquid or the bad characteristics that are difficult for producing distortion that reach of gas thorn.
Description of drawings:
Accompanying drawing 1 is the utility model structure sectional view.
1-rubber body among the figure, the 2-steel wire.
Embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
By shown in Figure 1, this metal frame seal ring comprises rubber body 1, rubber body 1 is built-in with steel wire 2, steel wire 2 outer vulcanized rubbers and being integral, interior steel wire 2 intensity height, outer rubber body 1 good springiness is difficult for by liquid or gas thorn bad when liquid or gas pressure are high, and be difficult for the generation distortion, so this metal frame seal ring has the intensity height, is difficult for by liquid or the bad characteristics that are difficult for producing distortion that reach of gas thorn.
Claims (3)
1, a kind of metal frame seal ring comprises rubber body (1), it is characterized in that: rubber body (1) is built-in with metal frame (2).
2, metal frame seal ring according to claim 1 is characterized in that: skeleton (2) is a steel wire.
3, metal frame seal ring according to claim 1 is characterized in that: the outer vulcanized rubber of steel wire (2) (1) and being integral.
