Description
Technical field
The utility model relates to pipe technology fields more particularly to a kind of transmission of Novel oil gas to use high-pressure hose.
Background technique
Currently, oil gas transmission pipeline in China's has about 600,000 kms to service life, and the main problem of pipe network is at present
Single layer hose bearing capacity is not high, and the layering of outer glue-line destructible leads to leak rate height, pipeline burst Frequent Accidents, causes environment
Pollution and the wasting of resources, and the reparation and substitute mode of " formula of cutting open the chest " of existing pipeline, had not only affected normal traffic circulation, but also
Pollution is brought to environment.
In oil gas transmission pipeline use process, flexible nonmetallic tubing often has outer surface to destroy the phenomenon that can not replying, and changes frequently
Replace time-consuming and laborious, project amount is big, seriously affects normal work and life.Under such background condition, a kind of no-dig technique pipe
Road repair hose demand come into being, can bear high pressure (various high-low pressures), meet various bores, releasing pressure automatically, can be extensive
Multiple requirement.
Utility model content
The purpose of this utility model is to provide a kind of Novel oil gas transmission high-pressure hoses, by being arranged in outer glue-line
Be conducive to the internal relief hole for gathering gas discharge, while using the double-deck aramid fiber enhancement layer, can both discharge the pressure in the hose
Power, and may insure the bearing capacity of the hose.
In order to achieve the above objectives, the technical solution adopted in the utility model is: a kind of Novel oil gas transmission high-pressure hose,
Including hookah bodies, inner glue layer, the first enhancement layer, the second enhancement layer and outer glue-line are successively arranged on the outside of the hookah bodies,
Along hookah bodies axis direction is parallel to equipped with multiple pressure release bands in the outer glue-line, the pressure release band includes outside multiple non-through
The relief hole of glue-line, one end of the relief hole are abutted against with the second enhancement layer, and the other end is located at the inside of outer glue-line, this is let out
Pressure is gradually reduced on hole along the hole internal diameter far from the second enhancement layer direction.
As further optimization, the relief hole is bellmouth or frustum of a cone hole.
As further optimization, distance of the one end apart from outer glue-line outer wall being located in outer glue-line on the relief hole is
0.05-0.30mm。
As further optimization, first enhancement layer and the second enhancement layer are aramid fiber braiding layer.
As further optimization, the inner glue layer and outer glue-line are fire-retardant glue-line.
As further optimization, the number of the pressure release band is six to ten.
Compared with prior art, the utility model has below the utility model has the advantages that by the way that multiple let out is arranged in outer glue-line
Hole is pressed, the form of traditional " stifled " is become into the scheme " dredged ", air-tight state is kept when daily and gas pressure is small, prevents
Substance in environment influences hose；When gathering gas in the hose and forming biggish outward pressure, can pass through relief hole will
Gas release, then relief hole is closed under the action of outer layer glue elasticity restoring force.
Detailed description of the invention
Fig. 1 is the axial sectional view of the utility model.
Fig. 2 is A-A cross-sectional view in Fig. 1.
In figure, 1. hookah bodies；2. inner glue layer；3. the first enhancement layer；4. the second enhancement layer；5. outer glue-line；6. pressure release band,
61. relief hole.
Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1 to Figure 2, a kind of Novel oil gas, which transmits, uses high-pressure hose, including hookah bodies 1, outside hookah bodies 1
Side is successively arranged inner glue layer 2, the first enhancement layer 3, the second enhancement layer 4 and outer glue-line 5, and edge is parallel to hookah bodies 1 in outer glue-line 5
Axis direction is equipped with multiple pressure release bands 6, and pressure release band 6 includes the relief hole 61 of multiple non-through outer glue-lines 5, one end of relief hole 61
It is abutted against with the second enhancement layer 4, the other end is located at the inside of outer glue-line 5, along far from 4 side of the second enhancement layer on the relief hole 61
To hole internal diameter be gradually reduced.
By the way that multiple relief holes 61 are provided in outer glue-line 5, the form of traditional " stifled " is become into the scheme " dredged ", pressure release
Hole 61 is non through hole, keeps air-tight state when daily and gas pressure is small, prevents the substance in environment from influencing hose；When
When gathering gas in the hose and forming biggish outward pressure, gas can be discharged by relief hole 61, then relief hole 61
It is closed under the action of 5 elastic restoring force of outer layer glue.
Relief hole 61 is bellmouth or frustum of a cone hole, and one end in outer glue-line 5 is located on relief hole 61 outside outer glue-line 5
The distance of wall is 0.05-0.30mm, is conducive to the discharge of gas and the closure of outer glue-line.
First enhancement layer 3 and the second enhancement layer 4 are aramid fiber braiding layer, solve the problems, such as low pressure-bearing using aramid fiber, are used
Double-layer structure, operating pressure reach as high as 16MPa；The gap of the structure of braiding is conducive to gather gas to relief hole 61 simultaneously
Position flowing.
Inner glue layer 2 and outer glue-line 5 are fire-retardant glue-line, and the flame retardant property of the hose can be improved.
The number of pressure release band 6 is six to ten, and multiple relief holes 61 are arranged on each pressure release band 6, increases collection in the hose
The release way of gather qi together body.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
