Abstract
The present invention relates to a kind of nonmetallic pipeline seal pipe connection component, including mandrel, pressure ring, spacing pressure ring and back-up ring, mandrel wall coaxial is formed with a plurality of spacing ring uniformly at intervals, and mandrel one end interference has a pressure ring, and the end of a pipeline is coaxially pressed abd fixed between mandrel and pressure ring；Mandrel other end interference has a spacing pressure ring, and coaxial be mounted has a back-up ring in the spacing pressure ring, and co-axial seal is set with another pipeline between the back-up ring and spacing pressure ring.The present invention is widely used in the connection of various nonmetal pipelines, is connected using high-precision mandrel, pressure ring, and quick construction, strength of joint is high, reaches good sealing, good endurance, service life length, good seal performance using metal tube interference fit.
Description
Technical field
The invention belongs to oil pipe connector, especially a kind of nonmetallic pipeline seal pipe connection component.
Background technology
With the change of oilfield exploitation environment, connection of the Various Complex such as deep-well, high-pressure oil-gas well hole condition for oil pipe is strong
Degree and sealing propose more preferable requirement.At present, the connection generally use clip for nonmetallic pipeline or card cover device enter
Row connection, pipeline link position need to use bolt to be fixed in outside, cause pipeline link position too fat to move, space-consuming
Greatly, easily influenceed by external force to cause sealing property to decline in use, and mounting process is more wasted time and energy.
The content of the invention
It is an object of the invention in place of overcome the deficiencies in the prior art, there is provided one kind is simple in construction, precision is high, connection is strong
High, the safe and reliable nonmetallic pipeline seal pipe connection component of degree.
The present invention solves its technical problem and takes following technical scheme to realize：
A kind of nonmetallic pipeline seal pipe connection component, it is characterised in that：Including mandrel, pressure ring, spacing pressure ring and gear
Circle, mandrel wall coaxial are formed with a plurality of spacing ring uniformly at intervals, and mandrel one end interference has a pressure ring, the end of a pipeline
Coaxially it is pressed abd fixed between mandrel and pressure ring；Mandrel other end interference has a spacing pressure ring, coaxial in the spacing pressure ring
Limit installation has a back-up ring, and co-axial seal is set with another pipeline between the back-up ring and spacing pressure ring.
Moreover, the conical surface is formed with the outer of axial one end of mandrel, and the outer wall of back-up ring is formed with the conical surface.
Moreover, the pressure ring is formed with taper chamfering towards one end internal diameter in the middle part of mandrel.
Moreover, the outer end of the spacing pressure ring is formed with transition annular groove, between transition annular groove corresponds to spacing pressure ring radial direction
Every the expansion screw hole for being formed with fixing screw hole and ellipse.
Moreover, the fixing screw hole and expansion screw hole eccentric setting.
The advantages and positive effects of the present invention are：
The present invention is widely used in the connection of various nonmetal pipelines, is connected, applied using high-precision mandrel, pressure ring
Work is quick, and strength of joint is high, reaches good sealing using metal tube interference fit, good endurance, service life is grown, close
Sealing property is good.

Embodiment
Below in conjunction with the accompanying drawings and the invention will be further described by specific embodiment, and following examples are descriptive
, it is not limited, it is impossible to which protection scope of the present invention is limited with this.
A kind of nonmetallic pipeline seal pipe connection component, including mandrel 3, pressure ring 4, spacing pressure ring 2 and back-up ring 1, mandrel
Wall coaxial is formed with a plurality of spacing ring 5 uniformly at intervals, and mandrel one end interference has a pressure ring 4, by pipeline during use
End is coaxially pressed abd fixed between mandrel and pressure ring；
Mandrel other end interference has a spacing pressure ring, and coaxial be mounted has a back-up ring 1, the gear in the spacing pressure ring
Co-axial seal is set with another pipeline between circle and spacing pressure ring.
It is interference fitted respectively with pressure ring and fiber pressure ring by mandrel both ends spacing ring, ensures that connection component sealing can
Lean on.
This product has 6 ", 8 ", 10 ", 12 " plurality of specifications.
For the ease of pipeline is sleeved on mandrel, the conical surface 6 is formed with the outer of axial one end of mandrel；The outer wall of back-up ring
It is formed with the conical surface.
For the ease of installing pressure ring, pressure ring is formed with taper chamfering 10 towards one end internal diameter in the middle part of mandrel.
The outer end of spacing pressure ring is formed with transition annular groove 7, convenient to insert pipeline in spacing pressure ring；Also, in order to ensure
Spacing pressure ring and back-up ring firmly install, transition annular groove correspond to spacing pressure ring spaced radial be formed with fixing screw hole 9 and
The expansion screw hole 8 of ellipse, two screw hole eccentric settings, erection ＆ lift fastness.
Although disclosing embodiments of the invention and accompanying drawing for the purpose of illustration, those skilled in the art can manage
Solution：Do not departing from the present invention and spirit and scope of the appended claims in, it is various replace, change and modifications all be it is possible,
Therefore, the scope of the present invention is not limited to embodiment and accompanying drawing disclosure of that.
