Description

Technical Field

[0001] The utility model belongs to the technical field of ultra-high pressure large-diameter hose structures, and in particular relates to an ultra-high pressure large-diameter hose assembly. Background Art

[0002] Ultra-high pressure hose assembly is a pipeline system used to transmit high-pressure liquid or gas, which is widely used in industrial fields such as petroleum, chemical industry, mining, etc. The hose assembly usually consists of a hose and a connector, which is used to connect the hose to other equipment or pipeline systems. In ultra-high pressure applications, it is very important to ensure the air tightness of the connector to avoid leakage or leakage and ensure the safe and reliable operation of the system.

[0003] However, the current ultra-high pressure hose assembly has some problems in the connection structure between the connector and the hose. In order to ensure the air tightness at the connector, the connection structure often needs to be designed to be very complicated. This may involve a combination of multiple sealing rings, gaskets, threads or nuts to ensure that the connection is tight and has good sealing performance. Such a complex structure requires the use of professional tools when disassembling the hose assembly in order to remove and loosen the connection parts layer by layer. This not only increases the complexity and difficulty of the operation, but also seriously reduces the efficiency of disassembly. In addition, this complex connection structure also brings inconvenience to daily maintenance and repairs, requiring professionals and special tools to operate, increasing the cost and time of maintenance.

[0004] Therefore, based on some of the above prior art situations, the present application has been further designed and improved. Utility Model Content

[0005] In view of the above deficiencies in the prior art, the present invention solves them through the following technical solutions.

[0006] An ultra-high pressure large-diameter hose assembly includes a hose body and a connector assembled at a port of the hose body. The connector is provided with an inner lining and an outer lining. When the hose body and the connector are assembled, the tube wall layer of the hose body is clamped and fixed between the inner lining and the outer lining. The inner lining and the outer lining are provided with fastening tooth rings for fixing the tube wall layer on the surfaces facing the tube wall layer. The outer lining is covered with a fastening sleeve for fastening the outer lining.

[0007] As a preferred embodiment of the ultra-high pressure large-diameter hose assembly described in the utility model, specifically, the outer lining portion includes an outer sleeve, the cross-section of the outer sleeve is Ω-shaped with a notch, so that the radial dimension of the outer sleeve can be contracted when the fastening sleeve and the outer lining portion are assembled; a connecting strip is provided on the outer sleeve, and the connecting strip is used to connect with the connecting head.

[0008] As a preferred embodiment of the ultra-high pressure large diameter hose assembly described in the utility model, specifically, the outer bushing is in the shape of a truncated cone that shrinks from the connecting portion to the free end, and the structure of the part of the squirrel fastening sleeve used to fasten the outer bushing matches the truncated cone shape.

[0009] As a preferred implementation scheme of the ultra-high pressure large diameter hose assembly described in the utility model, specifically, the angle α between the truncated cone side and the axis is 2°~5°.

[0010] As a preferred implementation scheme of the ultra-high pressure large diameter hose assembly described in the utility model, specifically, the connector is provided with an external thread, and the fastening sleeve is provided with an internal thread assembled and fixed with the external thread.

[0011] As a preferred embodiment of the ultra-high pressure large-diameter hose assembly described in the utility model, specifically, the pipe wall layer includes a corrosion-resistant layer, a reinforcement layer and a protective layer from the inside to the outside; the protective layer needs to be removed from the pipe wall layer used for assembly with the connector.

[0024] Reference Figures 1 to 5 , an ultra-high pressure large diameter hose assembly, comprising a hose body 10 and a connector 20 assembled at the port of the hose body 10. The connector 20 is provided with an inner lining 21 and an outer lining 22. When the hose body 10 and the connector 20 are assembled, the pipe wall layer of the hose body 10 is clamped and fixed between the inner lining 21 and the outer lining 22. The inner lining 21 and the outer lining 22 are provided with a fastening tooth ring 25 for fixing the pipe wall layer on the surface facing the pipe wall layer. The outer lining 22 is covered with a fastening sleeve 26 for fastening the outer lining 22.

[0025] Specifically, the outer lining 22 includes an outer sleeve 23, the cross section of which is in the shape of an Ω with a notch, so that the radial dimension of the outer sleeve 23 can be shrunk when the fastening sleeve 26 is assembled with the outer lining 22, and a connecting strip is provided on the outer sleeve 23, and the connecting strip is used to connect with the connector 20. This design enables the fastening tooth ring 25 located on the outer sleeve 23 to be more tightly embedded in the pipe wall layer, ensuring the sealing of the connection between the connector 20 and the pipe wall layer. Further, the outer sleeve 23 is in the shape of a truncated cone that shrinks from the connecting portion 24 to the free end, and the structure of the part of the squirrel fastening sleeve 26 used to fasten the outer sleeve 23 matches the truncated cone shape.

[0026] Furthermore, the angle α between the truncated cone side and the axis is 2° to 5°, so that the outer lining 22 can ensure the chimeric connection with the pipe wall layer during assembly, and can avoid excessive deformation and breakage of the connection part 24. In addition, in order to ensure that the connection head 20 and the fastening sleeve 26 are firmly connected, the connection head 20 is provided with an external thread 27, and the fastening sleeve 26 is provided with an internal thread assembled and fixed with the external thread 27.

[0027] In addition, the pipe wall layer includes a corrosion-resistant layer 11, a reinforcement layer 12 and a protective layer 13 from the inside to the outside. In order to ensure that the fastening tooth ring 25 can be firmly connected to the pipe wall layer, the protective layer 13 needs to be removed from the pipe wall layer used for assembly with the connector 20, so that the pipe wall layer used for engagement connection with the fastening tooth ring 25 is a relatively soft corrosion-resistant layer 11 and a reinforcement layer 12, so as to avoid sealing defects caused by the pipe wall layer being too hard.

[0028] The utility model can firmly assemble the connector 20 on the hose body 10. When disassembling, it is only necessary to loosen the fastening sleeve to relax the outer lining 22 to separate the connector 20 and the hose body 10 without the aid of professional tools, which greatly facilitates the maintenance of the pipeline.

[0029] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope of the present invention shall be based on the claims. Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field shall fall within the protection scope of the present invention.
