Description
Technical field
The utility model relates to Sealing field, particularly relates to a kind of Sealing back-up ring.
Background technique
At present, oil production equipment casing head and bobbin seal need easy for installation, reliability is high, due to the various complexity of applying working condition, faced by medium, pressure, temperature scope very wide, usually back-up ring and seal ring are supported the use, back-up ring can prevent seal ring under the effect of the pressure from being got into the gap of low voltage side, keep sealing effect, part play can also be prevented.Not only can improve the range of working pressure of seal ring, also serve the effect of protection seal ring.When oil production equipment casing head and bobbin seal, general employing be metal collar, but metal collar complex process, cost is high, metal collar aperture position is sharp, easy damaged Sealing, collar material adopts spring steel, not corrosion-resistant, back-up ring control gap ability during pressurized, metal collar resilience stress is large, installs difficulty, needs special tool to install.Therefore, urgently a kind of installation and when safeguarding dismounting convenient, cost is low, can ensure again the back-up ring of sealing property of sealing component.
Model utility content
For solving the problem, the utility model provides a kind of easy for installation and low Sealing back-up ring not damaging Sealing of cost.
The utility model solves the technological scheme that its technical problem adopts:
A kind of Sealing back-up ring, comprise the back-up ring body being applied to Sealing, back-up ring body comprises some mutually linking and closely stacking wire, and each port wiry is all hidden in back-up ring body interior.
Be further used as the improvement of technical solutions of the utility model, material wiry is stainless steel.
Be further used as the improvement of technical solutions of the utility model, stainless steel is S316.
Be further used as the improvement of technical solutions of the utility model, the sectional shape of back-up ring body is rectangle.
Be further used as the improvement of technical solutions of the utility model, back-up ring body adopts mould compressing.
The beneficial effects of the utility model: the back-up ring body of this Sealing back-up ring comprises some mutually linking and closely stacking wire, make back-up ring have bending rebound elasticity, install simple, cost is low, closely stacking wire has certain degree of compaction, without extruding gap, anti-extrusion is effective, and each port wiry is all hidden in back-up ring body interior, whole back-up ring is without sharp opening, can not rubber seal be damaged, and uniform force, overall tightness is good.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model embodiment overall structure schematic diagram;
Fig. 2 is the utility model embodiment partial sectional view;
Fig. 3 is the partial sectional view that the utility model embodiment is applied to Sealing.
Embodiment
Be clearly and completely described below with reference to embodiment and the accompanying drawing technique effect to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.Obviously; described embodiment is a part of embodiment of the present utility model, instead of whole embodiment, based on embodiment of the present utility model; other embodiments that those skilled in the art obtains under the prerequisite not paying creative work, all belong to the scope of the utility model protection.
With reference to Fig. 1 ~ Fig. 3, the utility model is a kind of Sealing back-up ring, comprises back-up ring body 1, and back-up ring body 1 comprises some mutually linking and closely stacking wire, and it is inner that each port wiry is all hidden in back-up ring body 1.
The back-up ring body 1 of this Sealing back-up ring comprises some mutually linking and closely stacking wire, make back-up ring have bending rebound elasticity, install simple, cost is low, closely stacking wire has certain degree of compaction, without extruding gap, anti-extrusion is effective, and it is inner that each port wiry is all hidden in back-up ring body 1, whole back-up ring is without sharp opening, can not rubber seal be damaged, and uniform force, overall tightness is good.
As the utility model preferred embodiment, material wiry is stainless steel.
Stainless steel back-up ring has bending rebound elasticity, and install very simple, temperature resistant range is at-80 DEG C ~ 200 DEG C.Tackling different work condition environments selects the stainless steel of the different trade mark to remove opposing acid and alkali corrosion etc.
As the utility model preferred embodiment, stainless steel is S316.
Wire netting back-up ring adopts stainless steel S316 material, and corrosion resistance is strong, is applicable to oil drilling equipment.
As the utility model preferred embodiment, the sectional shape of back-up ring body 1 is rectangle.
The utility model is applicable to the back-up ring of different cross section shape.
As the utility model preferred embodiment, back-up ring body 1 adopts mould compressing.
Sealing back-up ring adopts mould-forming, and make the back-up ring adopting Stainless Steel Wire to make have certain degree of compaction, anti-extrusion is effective, the gap between each wire and wire, and thermal diffusivity is good, improves heat resistance.And not only do not slacken the structural strength of back-up ring, also make back-up ring have good elasticity and expansion coefficient.During expansion, extrude the gap between each wire and wire, make wire netting back-up ring by compression swelling time without extruding gap, overall tightness is good.Mould-forming, technique is simple, and production efficiency is high, and cost is low.
Molding mode of the present utility model is roughly, and adopts wire to knit into net, then shears materials for later use, last compression molding.
Certainly, the invention is not limited to above-mentioned mode of execution, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent distortion or replacement are all included in the application's claim limited range.
