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 technology
Sealing problem after petroleum pipeline docking is a critically important problem, the commonly used flange-interface of prior art is attached and seals, its structure is complex, and the pulling force that during flange-interface sealing, bolt bears is larger, the pulling force that bolt bears is delivered on flange, also easily damage is brought to flange, so the requirement to flange is higher.Simultaneously as bearing big stress for a long time, the bolt of flange and adpting flange after being used for a while, will necessarily produce fatigue stress phenomenon, so use time is more long more easily occurring damaging.
Simultaneously as petroleum pipeline is during high pressure, high speed convey, the sealing under pipe high-pressure environment is also the technical problem that prior art is faced, and connects high pressure, the requirement of conveying at a high speed that can not meet increasingly increase using conventional flange.
Content of the invention
The technical problem excessive in order to solve the pipe end constructions seal structure complex of petroleum pipeline, stress, solves the problems, such as petroleum pipeline pressure-bearing, the present invention provides a kind of high pressure delivery pipes embedded interface structure simultaneously.
The purpose of the present invention to implement by the following technical programs：
A kind of high pressure delivery pipes embedded interface structure, including embedded pipe, outer tube and two pipe end constructions, connected by embedded pipe between two described pipe end constructions, the two ends of described embedded pipe are docked with two described pipe end constructions ends, the outside of each pipe end constructions is provided with screw thread, described outer tube is connected with two pipe end constructions by screw thread, the end sides of each described pipe end constructions are provided with ring cutting groove, the two ends of described embedded pipe are bonded with ring-type plastic strip respectively, the lateral surface of described ring-type plastic strip is provided with circular fin, the ring cutting groove fit of described circular fin and described pipe end constructions is installed.
The middle part of described outer tube is provided with integrally formed hex 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 tube, two pipe end constructions are connected, and installed by the ring-type plastic strip and ring cutting groove fit at embedded pipe two ends between two pipe end constructions, realize after holding out against being tightly connected, due to the presence of outer tube, embedded pipe itself can be with pressure-bearing, and ring cutting groove can prevent the embedded pipe with ring-type plastic strip from moving radially, ensure that link position consolidates, sidesway will not be produced.
