Abstract

A kind of high pressure flange rubber seal relates to the sealed member between a kind of high pressure flange dish.It is characterized in that the high pressure flange rubber seal of ring-type, its cross section is a Long Hexagon.Usefulness is: simple in structure, and convenient processing and manufacture, cost is low.Under the 15-20Mpa working pressure, can use length for a long time, also can not produce leakage, can significantly reduce the number of times of operation, reduce operating cost, help producing.Because the sealing circle is manufactured with rubber material, in transportation or installation process, do not need specially careful, easy to use.The utility model is specially adapted on the injection well head assembly in oil field.

Description

The high pressure flange rubber seal
Technical field
The utility model relates to the sealed member between a kind of high pressure flange dish.
Background technique
On the well mouth of oil well in oil field or on the pipeline of high-pressure delivery liquid, as required, adopt flange that pipeline is linked together sometimes, at this moment just need sealing between the flange, prevent leaked liquid.Way at present commonly used is that to be processed with cross section respectively on two flanged surfaces be trapezoidal annular groove, and the seal ring of making of steel is installed in annular groove, and the requirement on machining accuracy of this steel seal ring is very high, and the comparison difficulty is manufactured in processing, and cost is higher.And in transportation or installation process, want extreme care,, influence its sealing effect in order to avoid its surface sustains damage.This steel seal ring of particularly on the water injection well well head, installing, because of the sewage of being annotated has very strong corrosivity, after after a while, the surface etching of steel seal ring will be gone out many age spots, make it lose the function of sealing, produce leakage, will go up the big four that the operating personnel changes seal ring or well head, so not only influence the ordinary production of water injection well, also increase cost of production.
The model utility content
The purpose of this utility model is that simple, non-damageable high pressure flange rubber seal is manufactured in a kind of processing of design.
Technical solution of the present utility model is achieved in that a kind of high pressure flange rubber seal, is made of the rubber ring of ring-type, and its special way is that its cross section is a Long Hexagon.
Usefulness of the present utility model is: (1) is simple in structure, convenient processing and manufacture, and cost is low.(2) because rubber has certain elasticity,, can not produce leakage even be corroded in the seal groove of flange yet, service time is long, can significantly reduce the number of times of operation, reduces operating cost, and can make water injection well keep long up-time, help producing.(3) because the sealing circle is manufactured with rubber material, in transportation or installation process, do not need specially careful, easy to use.
Description of drawings
Accompanying drawing is a sectional structure chart of the present utility model.
Embodiment
Selecting hardness for use is the anti-corrosive rubber of 85 ± 5 Shao Er, and this high pressure flange rubber seal 1 is manufactured in processing, and its cross section becomes Long Hexagon, and the angle between the surface 2 of homonymy and the surface 3 and the angle of the seal ring on the flange plate adapt.Perhaps its cross section is made into ellipse.This seal ring is installed on the water injection well well head, and water injection pressure can use for a long time at 15-20MPa, need not change seal ring, also need not carry out operation, accomplishes safety in production.

Claims (1)

1, a kind of high pressure flange rubber seal, rubber ring (1) formation by ring-type is characterized in that its cross section is a Long Hexagon.
