Abstract
The utility model discloses a blowout preventer side door seal ring which comprises a first annular steel ring (1) and a second annular steel ring (2), wherein the first annular steel ring (1) is overlapped on the second annular steel ring (2); annular seal bars (3) are connected inside the first annular steel ring (1) and the second annular steel ring (2); and steel wire cloth (4) is filled between the first annular steel ring (1) and the second annular steel ring (2). The high-strength steel wire cloth is filled between the two annular steel rings and used for binding and connecting the two annular steel rings, the integral high-pressure resistance strength of the seal ring is improved, and the blowout preventer side door seal ring is difficult to deform and damage, and has a better seal effect. The utility model belongs to the technical field of seal fittings.
Description
Technical field
The utility model belongs to the seal fitting technical field, especially relates to a kind of side door of blowout preventer seal ring.
Background technique
Preventer is to be used for operation process such as formation testing, well workover, completion to cut out well head, prevents a kind of machinery that gas blowout accident takes place.During oil drilling, be installed on the well head casing head, be used for controlling the blowout device of high pressure oil, gas, water.When the OIH atmospheric pressure was very high, preventer can seal well head (closing dead).When in drilling rod, being pressed into weighted mud, under its flashboard four-way is arranged, the replaceable mud that goes out to receive gas cut, the pressure of fluid column in the increase well is to push down the ejection of high-pressure oil gas.The quality that is applied in the sealability of the side door of blowout preventer seal ring on the preventer directly has influence on the quality of preventer.
Existing side door of blowout preventer seal ring is formed by stacking on two annular steel rings, and the steel ring inboard is provided with rubber ring, and the steel ring outer surface is surrounded by Stamping Steel Ribbon, is filled with rubber between two steel rings.The sealing circle is applied in the middle of the hyperbaric environment, and the pressure that receives is bigger, and only adopts rubber to fill between the two annular steel rings, and the join strength between two steel rings is not enough, causes in hyperbaric environment, being prone to deform, and influences sealing at last.
Summary of the invention
The utility model technical problem to be solved is: the side door of blowout preventer seal ring of carrying intensity height, good sealing effect.
The technological scheme that the utility model is taked is: a kind of side door of blowout preventer seal ring; Comprise the first annular steel ring and the second annular steel ring; The first annular steel ring is stacked on the second annular steel ring; Be connected with annular sealing strip in the first annular steel ring and the second annular steel ring, filler wires cloth between the first annular steel ring and the second annular steel ring.
Described steel wire is furnished with many ring like steel wire and is formed by stacking successively, and many ring like steel wire spray rubber outward.
The beneficial effect of the utility model is: is filled with high-intensity ring like steel wire between the two annular steel rings of the utility model both coupled together, improved the whole anti-high voltage intensity of seal ring, and not yielding when practical, also be difficult for coming unstuck, sealing effect is better.
Description of drawings
Fig. 1 is the utility model sectional view.
Fig. 2 is an A-A view among Fig. 1.
Among the figure, 1, the first annular steel ring, 2, the second annular steel ring, 3, annular sealing strip, 4, card clothing.
Embodiment
Below be the utility model preferred embodiment, but therefore do not limit the protection domain of the utility model.
In conjunction with Fig. 1, shown in Figure 2; A kind of side door of blowout preventer seal ring of the utility model; Comprise the first annular steel ring 1 and the second annular steel ring 2; The first annular steel ring 1 is stacked on the second annular steel ring 2, is connected with filler wires cloth 4 between annular sealing strip 3, the first annular steel rings 1 and the second annular steel ring 2 in the first annular steel ring 1 and the second annular steel ring 2.
Described card clothing 4 has many ring like steel wire to be formed by stacking successively, and many ring like steel wire spray rubber outward.
Be filled with high-intensity card clothing 4 between the two annular steel rings both are intertwined and connected, improved the whole anti-high voltage intensity of seal ring, not yielding when practical, also be difficult for coming unstuck, sealing effect is better.
Claims (2)
1. side door of blowout preventer seal ring; Comprise the first annular steel ring (1) and the second annular steel ring (2); The first annular steel ring (1) is stacked on the second annular steel ring (2); Be connected with annular sealing strip (3) in the first annular steel ring (1) and the second annular steel ring (2), it is characterized in that: filler wires cloth (4) between the first annular steel ring (1) and the second annular steel ring (2).
2. side door of blowout preventer seal ring according to claim 1 is characterized in that: described card clothing (4) has many ring like steel wire to be formed by stacking successively, and many ring like steel wire spray rubber outward.
