Abstract
The invention discloses an embedded port structure for high-pressure delivery pipelines. The embedded port structure comprises an inner embedded pipe, an outer sleeve and two pipe-end structures. The two pipe-end structures are connected with each other by the inner embedded pipe, two ends of the inner embedded pipe are in butt joint with the ends of the two pipe-end structures, threads are arranged on the outside of each pipe-end structure, the outer sleeve is connected with the two pipe-end structures in a threaded manner, annularly cut grooves are formed in side surfaces of an end of each pipe-end structure, annular plastic strips are respectively adhered at the two ends of the inner embedded pipe, and annular ribs are arranged on the outer side surfaces of the annular plastic strips and are fittingly mounted with the annularly cut grooves of the pipe-end structures. The embedded port structure for the high-pressure delivery pipelines has the advantages that the two pipe-end structures are connected with each other by the outer sleeve, the annular plastic strips at the two ends of the inner embedded pipe are fittingly mounted with the annularly cut grooves, so that the two pipe-end structures can be hermetically connected with each other after the annular plastic strips are abutted to the annularly cut grooves.
Description
Technical field
The present invention relates to a kind of high pressure delivery pipes embedded interface structure, belong to high-pressure delivery petroleum pipeline technical field.
Background technique
Sealing problem after the petroleum pipeline butt joint is a very important problem, prior art is often used flange-interface to connect and is sealed, its structure is comparatively complicated, and the pulling force that bolt bears in the process of flange-interface sealing is bigger, the pulling force that bolt bears is delivered on the flange, also easily flange is brought damage, thus to the requirement of flange than higher.Simultaneously, owing to bear big stress effect for a long time, the bolt that flange and adpting flange are used will inevitably produce the fatigue stress phenomenon after using a period of time, so service time, more easy appearance more of a specified duration damaged.
Simultaneously, because petroleum pipeline is in high pressure, the process of carrying at a high speed, the sealing under the pipeline hyperbaric environment also is the technical problem that prior art faces, and adopts conventional flange to connect and can not satisfy the high pressure that increases day by day, the requirement of carrying at a high speed.
Summary of the invention
In order to solve the excessive technical problem of pipe end constructions seal structure complex, stress of petroleum pipeline, solve the problem of petroleum pipeline pressure-bearing simultaneously, the invention provides a kind of high pressure delivery pipes embedded interface structure.
Purpose of the present invention is come specific implementation by the following technical programs:
A kind of high pressure delivery pipes embedded interface structure, comprise embedded pipe, outer sleeve and two pipe end constructions, connect by embedded pipe between two described pipe end constructions, dock with two described pipe end constructions ends at the two ends of described embedded pipe, the outside of each pipe end constructions is provided with screw thread, described outer sleeve is connected with two pipe end constructions by screw thread, the end sides of each described pipe end constructions is provided with the ring cutting groove, the two ends of described embedded pipe are bonded with the ring-type plastic strip respectively, the outer side surface of described ring-type plastic strip is provided with circular fin, and the ring cutting groove fit of described circular fin and described pipe end constructions is installed.
The middle part of described outer sleeve is provided with integrated hexagon nut structure.
The cross section of described ring cutting groove is rectangle.
A kind of high pressure delivery pipes embedded interface structure of the present invention, by outer sleeve two pipe end constructions are connected, and ring-type plastic strip and the ring cutting groove fit by embedded pipe two ends installed between two pipe end constructions, holding out against the back realizes being tightly connected, because the existence of outer sleeve, embedded pipe itself can pressure-bearing, and the ring cutting groove can prevent from having the embedded caliber of ring-type plastic strip to movement, the assurance link position is firm, can not produce sidesway.

The middle part of described outer sleeve 2 is provided with integrated hexagon nut structure 6.
The cross section of described ring cutting groove is rectangle.
A kind of high pressure delivery pipes embedded interface structure of the present invention, by outer sleeve two pipe end constructions are connected, and ring-type plastic strip and the ring cutting groove fit by embedded pipe two ends installed between two pipe end constructions, holding out against the back realizes being tightly connected, because the existence of outer sleeve, embedded pipe itself can pressure-bearing, and the ring cutting groove can prevent from having the embedded caliber of ring-type plastic strip to movement, the assurance link position is firm, can not produce sidesway.
