Abstract

The utility model relates to a high-sealing-performance flange comprising a main body (1), a groove (2), a small boss (3), a sealing pad (4) and a big boss (5), wherein the main body (1) of the high-sealing-performance flange is of an annular structure and used in pairs; a center hole (A) is arranged in the main body; more than four bolt holes (B) are uniformly distributed in the outer circumference of the main body; the annular big boss (5) is arranged between the center hole (A) and the bolt holes (B); one position in the middle of the annular big boss (5) is provided with the annular groove (2) while the other position is provided with the annular small boss (3); the annular sealing pad (4) is arranged in the groove (2); and the sealing pad (4) is pressed by the small boss (3). The flange disclosed by the utility model is simple in structure and reliable in sealing and suitable for crude oil collecting and transmitting pipelines of heavy oil wells of oil fields and has the advantages that the rated pressure of sealing work is up to 4MPa; the failure processing pressure is up to 12MPa; the crude oil and sewage loss is reduced; the environmental pollution is reduced; the labour intensity of workers is reduced; the time of processing the pipeline blocking failure is shortened; and the normal production of the crude oil of the oil fields is guaranteed.

Description

The high sealing performance flange
Technical field
The utility model relates to the pipeline valve connecting accessory, specifically a kind of high sealing performance flange.
Background technique
At present in field produces; crude oil gathering pipeline design rated working pressure 2.5MPa; and in producing in the winter time; particularly thick oil well is owing to producing the reasons such as undesired or power failure; often cause pipeline to stop up; in case the pipeline plugging fault occurs, needs to use hot sewage; the cement pump truck is processed, and it is also not smooth that pressure reaches the above pipeline of 12 MPa sometimes; conventional flange mat often thorn is bad; sometimes also the staff is stabbed, cause crude oil loss and environmental pollution, because common flange plane sealing structure problem; need repeatedly add mat; make the pipeline plugging fault processing time long, cause worker's labor intensity large; it is long to stop the well time, affects oil well and normally produces.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of high sealing performance flange is provided.
The technical solution of the utility model comprises: main body, groove, small boss, sealing gasket, large boss.The main body of its high sealing performance flange is cirque structure, use in pairs, be provided with center hole, the outside in the circumference uniform 4 with upper bolt hole, be provided with the large boss of annular between center hole and bolt hole, a slice is provided with annular groove in the middle of the large boss of annular, and another sheet is provided with annular small boss, be placed with Gask-O-Seal in the groove, small boss is pushed down sealing gasket.
The beneficial effects of the utility model are: simple in structure, sealing is reliable, be suitable for the oil-field thick-oil well crude oil gathering pipeline, specified sealed operating pressure 4MPa, processing pipeline plugging fault pressure can reach 12 MPa, reduces crude oil, sewage loss, reduce befouling environment, alleviate worker's labor intensity, shorten the processing pipeline plugging fault time, the assurance crude oil is normally produced.
Description of drawings
