Abstract
The invention relates to a seal pipe connecting assembly for nonmetallic pipelines. The seal pipe connecting assembly comprises a core shaft, a compression ring, a limiting compression ring and a check ring, wherein a plurality of limiting rings are coaxially and uniformly distributed on the outer wall of the core shaft at intervals; the compression ring sleeves one end of the core shaft in an interference manner; the end part of one pipeline is coaxially pressed and fixed between the core shaft and the compression ring; the limiting compression ring sleeves the other end of the core shaft in an interference manner; the check ring is coaxially mounted inside the limiting compression ring in a limiting manner; the other pipeline is coaxially sleeved by the part between the check ring and the limiting compression ring in a sealing manner. The seal pipe connecting assembly is widely applicable to the connection of various nonmetallic pipelines, the high-precision matching connection between the core shaft and the compression ring is adopted, the construction is quick, the joint strength is high, good sealing property is achieved by virtue of the interference fit of metal pipe fittings, the durability is good, the service life is long, and the sealing property is excellent.
Description
Technical field
The invention belongs to oil pipe connector, especially a kind of nonmetal pipeline sealed tube coupling assembling.
Background technology
Along with the change of oilfield exploitation environment, the Various Complex such as deep-well, high-pressure oil-gas well hole condition proposes better requirement for the bonding strength of oil pipe and sealing.At present, connection for nonmetal pipeline adopts clip or card cover device to connect usually, pipeline link position needs to use bolt to be fixed in outside, cause pipeline link position too fat to move, take up room large, easily affecting by external force in using causes sealing performance to decline, and mounting process is comparatively wasted time and energy.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, the nonmetal pipeline sealed tube coupling assembling that a kind of structure is simple, precision is high, bonding strength is high, safe and reliable is provided.
The present invention solves its technical problem and takes following technical scheme to realize:
A kind of nonmetal pipeline sealed tube coupling assembling, it is characterized in that: comprise mandrel, pressure ring, spacing pressure ring and back-up ring, mandrel wall coaxial is shaped with many spacing rings 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 in this spacing pressure ring, coaxial limit mounting has a back-up ring, and between this back-up ring and spacing pressure ring, co-axial seal is set with another root pipeline.
And, be shaped with the conical surface in the outer of axial one end of mandrel, and the outer wall of back-up ring is shaped with the conical surface.
And one end internal diameter of described pressure ring in the middle part of mandrel is shaped with taper chamfering.
And the outer end of described spacing pressure ring is shaped with transition cannelure, be shaped with the expansion screw hole of fixing screw hole and ellipse at the corresponding spacing pressure ring spaced radial of transition cannelure.
And, described fixing screw hole and expansion screw hole eccentric setting.
Advantage of the present invention and good effect are:
The present invention is widely used in the connection of various nonmetal pipeline, and adopt high-precision mandrel, pressure ring is connected, quick construction, strength of joint is high, utilizes the sealing that metal tube interference fit reaches good, good endurance, long service life, good seal performance.

Detailed description of the invention
Below in conjunction with accompanying drawing, also by specific embodiment, the invention will be further described, and following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
A kind of nonmetal pipeline sealed tube coupling assembling, comprise mandrel 3, pressure ring 4, spacing pressure ring 2 and back-up ring 1, mandrel wall coaxial is shaped with many spacing rings 5 uniformly at intervals, mandrel one end interference has a pressure ring 4, is coaxially pressed abd fixed between mandrel and pressure ring the end of a pipeline during use;
Mandrel other end interference has a spacing pressure ring, and in this spacing pressure ring, coaxial limit mounting has a back-up ring 1, and between this back-up ring and spacing pressure ring, co-axial seal is set with another root pipeline.
By mandrel two ends spacing ring respectively with pressure ring and fiber pressure ring interference fit, ensure that coupling assembling sealing is reliable.
This product has 6 ", 8 ", 10 ", 12 " plurality of specifications.
For the ease of being sleeved on mandrel by pipeline, be shaped with the conical surface 6 in the outer of axial one end of mandrel; The outer wall of back-up ring is shaped with the conical surface.
For the ease of installing pressure ring, one end internal diameter of pressure ring in the middle part of mandrel is shaped with taper chamfering 10.
The outer end of spacing pressure ring is shaped with transition cannelure 7, conveniently inserts in spacing pressure ring by pipeline; Further, firm in order to ensure the installation of spacing pressure ring and back-up ring, be shaped with the expansion screw hole 8 of fixing screw hole 9 and ellipse at the corresponding spacing pressure ring spaced radial of transition cannelure, these two screw hole eccentric settings, erection & lift fastness.
Although disclose embodiments of the invention and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the present invention and claims, various replacement, change and amendment are all possible, therefore, scope of the present invention is not limited to the content disclosed in embodiment and accompanying drawing.
