Description

Connecting sealing ring for deep sea petroleum drilling and production equipment

Technical Field

The utility model relates to the technical field of sealing rings, in particular to a connecting sealing ring for deep sea petroleum drilling equipment.

Background

The sealing ring is a ring-shaped sealing member with a notch, and is tightly pressed against the inner hole wall of the static member by the elasticity of the sealing ring after being pressed, and the sealing ring is made of chromium-containing wear-resistant cast iron or tin bronze.

When the sealing ring is used, the situation that a plurality of groups of sealing rings are overlapped and used can be met, but the existing sealing ring does not have a multi-stage overlapped structure, so that the upper part and the lower part of the plurality of groups of sealing rings are uneven, further, the stress is uneven, and the sealing quality is affected, and therefore the sealing ring with the multi-stage overlapped structure is needed.

Disclosure of Invention

The utility model aims to solve the defects that the prior sealing ring does not have a multi-stage superposition structure and the like in the prior art, and provides a connecting sealing ring for deep sea petroleum drilling equipment.

In order to achieve the above purpose, the present utility model adopts the following technical scheme:

the utility model provides a connect sealing ring that deep sea oil drilling equipment was used, includes the ring body, the slope groove has been seted up to the inboard of ring body lower extreme, the inboard of ring body upper end seted up with slope groove matched with slope convex ring, be located on the lower terminal surface of ring body the annular empty slot has been seted up to the periphery in slope groove, fixedly connected with connecting piece between the inboard terminal surface in empty slot.

Preferably, the cross section of one end of the sloping convex ring is in a right trapezoid structure.

Preferably, threads extending to the inner end face of the sloping convex ring are formed on the inner end face of the ring body above the sloping groove.

Preferably, a limiting ring is fixedly arranged on the inner side end surface of the upper end of the sloping convex ring.

Preferably, the connecting piece is a plurality of groups of elastic metal sheets with S-shaped structures, and the left end and the right end of the connecting piece are respectively and fixedly connected with the end faces of the left side and the right side in the empty groove.

Preferably, the inside of the empty groove is located at the upper end of the connecting piece and fixedly connected with an annular filling piece, and the filling piece is a nitrile rubber ring.

The connecting sealing ring for the deep sea petroleum drilling and production equipment has the beneficial effects that:

the slope-shaped convex rings with the right trapezoid cross section structure not only can play a role in positioning vertically, but also can improve the sealing effect in an extrusion state, and is convenient to install and use;

through the empty slot of seting up for the ring body has better elasticity, provides the expansion space, improves life and durability.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

Referring to fig. 1-4, a connecting sealing ring for deep sea petroleum drilling equipment comprises a ring body 1, wherein a sloping groove 2 is formed in the inner side of the lower end of the ring body 1, a sloping convex ring 3 matched with the sloping groove 2 is formed in the inner side of the upper end of the ring body 1, an annular empty groove 6 is formed in the lower end face of the ring body 1 and positioned at the periphery of the sloping groove 2, and a connecting piece 7 is fixedly connected between the inner end faces of the empty groove 6.

The cross section of one end of the sloping convex ring 3 is in a right trapezoid structure, so that one end facing the inner side of the ring body 1 is level with the inner side end surface of the ring body 1.

Threads 4 extending to the inner side end surface of the sloping convex ring 3 are arranged above the sloping groove 2 on the inner side end surface of the ring body 1, so that the ring body is convenient to connect with an external pipeline and is convenient to install.

The limiting ring 5 is fixedly arranged on the inner side end surface of the upper end of the slope-shaped convex ring 3, so that an external pipeline is prevented from passing through, and the limiting ring 5 can be arranged on one group of ring bodies 1.

The connecting piece 7 is a plurality of groups of elastic metal sheets with S-shaped structures, and the left end and the right end of the connecting piece 7 are respectively fixedly connected with the left end face and the right end face of the inside of the empty groove 6 to play a role in elastic support.

The inside of the empty groove 6 is fixedly connected with an annular filling piece 8 at the upper end of the connecting piece 7, and the filling piece 8 is a nitrile rubber ring, plays an elastic supporting role and has oil resistance.

The working mode is as follows; during operation, the multiple groups of ring bodies 1 are sequentially sleeved to the required number up and down through the slope-shaped grooves 2 and the slope-shaped convex rings 3, then the external pipeline is connected with threads on the outermost group of ring bodies 1, the external pipeline can be provided with a structure matched with the ring bodies 1 and the slope-shaped grooves 2 so as to improve the sealing effect, and finally the combination body of the multiple groups of ring bodies 1 and the external pipeline is placed in an external sleeve to be pressed and sealed, so that the installation can be completed.

The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
