Abstract
The utility model belongs to sealing ring technical field, discloses a kind of compressed natural gas oil expeller high-pressure seal ring, for solving the existing manufacture for solving existing sealing ring presence, installing the problem of changing difficult.The utility model includes lip-shaped sealed ring, it is characterised in that the pressure-bearing portion of the lip-shaped sealed ring is provided with stainless steel spring circle flexible back bone.Compressed natural gas oil expeller high-pressure seal ring of the present utility model, stainless steel spring circle flexible back bone is devised at sealing ring pressure-bearing position, so as to improve the anti-high pressure ability of sealing ring, stainless steel spring circle flexible back bone has certain flexibility, the problem of solving manufacture, installation and the difficult replacing that existing rigid backbone is present.
Description
Technical field
The utility model belongs to sealing ring technical field, and in particular to a kind of compressed natural gas oil expeller high-pressure seal ring.
Background technology
Gas storage compressed natural gas oil expeller high pressure lip type ground rice circle is the Special seal element of fast opening blind, and its effect is
Prevent equipment in normal course of operation because of the washing away of impurity, medium in the fluctuation, the influence of operating temperature, medium of operating pressure
The reason such as burn into rubber material ages and potted component is failed, stop so as to produce natural gas leaking, exploding and firing, equipment
The harm such as fortune.
High pressure lip-shaped sealed ring is mounted on the oil expeller of gas storage electric driven compression unit, once occur potted component
Failure, will directly contribute equipment stoppage in transit, then influence compressor set normal operation, not only influence the gas injection of whole gas storage
Yield, and be likely to result in natural gas leaking irritability catch fire, casualties situations such as.
The high-pressure seal ring for oil removing of natural gas device includes two kinds of structures in the prior art：A kind of lip-shaped sealed ring is complete
Rubber structure, this structure is easily damaged under pressure causes seal failure；Another lip type in full rubber structure is close
Increase sets rigid backbone in seal, because the outer ring of sealing ring and seal groove must be close, therefore, is manufactured to sealing ring and raw
Production is extremely difficult, while also causing in-site installation and changing extremely difficult.
Utility model content
The utility model provides a kind of to solve the problem of manufacture, installation that existing sealing ring is present change difficult
Compressed natural gas oil expeller high-pressure seal ring.
In order to solve the above technical problems, the technical scheme that the utility model is used is：
A kind of compressed natural gas oil expeller high-pressure seal ring, including lip-shaped sealed ring, it is characterised in that the lip-type seal
The pressure-bearing portion of circle is provided with stainless steel spring circle flexible back bone.
The stainless steel spring circle flexible back bone and lip-shaped sealed ring are cemented together through the vulcanization of rubber.
The lip-shaped sealed ring includes upper lip, lower lip and the connecting portion for connecting upper lip and lower lip, the upper lip
Openend and the openend of lower lip have opening, have the cavity with open communication between the upper lip, lower lip and connecting portion.
The upper lip is inclined to be connected on connecting portion, and upper lip is obliquely installed along the direction away from cavity.
The open end of the upper lip is one towards the inclined inclined plane of cavity.
Compared with prior art, the utility model has the advantages that：
Compressed natural gas oil expeller high-pressure seal ring of the present utility model, stainless steel bomb is devised at sealing ring pressure-bearing position
Spring coil flexible back bone, so as to improve the anti-high pressure ability of sealing ring, stainless steel spring circle flexible back bone has certain flexibility, solution
The problem of manufacture, installation and difficult replacing that existing rigid backbone of having determined is present.
The lip type structure design of sealing ring of the present utility model, has sealing compared to lip-shaped sealed ring of the prior art
The characteristics of effect is good.
