Description
Technical field
The present invention relates to high-pressure rubber pipe technical fields, more particularly to a kind of impact resistance high-pressure rubber pipe.
Background technique
High-pressure rubber pipe is mainly used for mine hydraulic support, oil field development, engineering construction, lifting transport, metallurgy forging and stamping, mine
It is conveyed in equipment, ship, injection machine, agricultural machinery, various lathes and each industrial department mechanization, automation hydraulic system
Petroleum base (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) with certain pressure and temperature and water fluid is (such as
Emulsion, oil-water emulsion, water) etc. and liquid transmission pipeline.
High-pressure rubber pipe when in use, although, if improper use, also can greatly shorten under the premise of quality is guaranteed
Sebific duct ground service life.In real work, damaging to most of high-pressure rubber pipe is all as caused by improper use.Main cause
Have: (1) by frequent, violent compression shock.High-pressure rubber pipe bursts, be generally not because bear static pressure it is too big caused by, and
It is related with the severe degree of compression shock and number.Engineering machinery the unexpected of oil pressure can occur in operation repeatedly in oil pipe
The case where being raised and lowered, so that constitute causes the oil sealing in each portion to damage aggravation, sebific duct appearance to the frequent compression shock of oil pipe
The loose leaky phenomenon of blistering and rupture and pipe fitting.Therefore in operation, pulling for valve rod can not be too quickly, has to put down
It is slow.(2) the use temperature of oil liquid is excessively high.When engineer machinery operation, hydraulic system makes oil liquid generate heat because of power loss, in addition outer
The influence (especially in summer) of boundary's temperature, can be such that oil temperature sharply increases.Oil liquid is higher using temperature, and rubber is more easy to aging, elasticity
It is deteriorated, intensity and sealing performance decline, and sebific duct will burst quickly.Therefore, in operation, when temperature rise occurs in hydraulic system
When high, too fast, it should ascertain the reason, be excluded in time；Summer operation when especially working continuously, should take necessary cooling
Measure.(3) sebific duct select, install it is unreasonable.When replacing high-pressure rubber pipe, length, the steel wire number of plies, the connector shape of selected sebific duct
Shape and size will be reasonable, and should minimize sebific duct bending degree；When tightening collar nut, sebific duct not made to generate torsion
Song, excessive bending and distortion will be greatly reduced the service life of sebific duct；Some positions for being easy to happen friction should be taken anti-
Shield measure, to prevent sebific duct from bursting because of abrasion.Above-mentioned failure, so that high-pressure rubber pipe in routine use, is relatively easy to because of height
The working environment of low temperature uses and leads to aging, and the service life is lower, and replacement is more frequent, influences mine, oil field, engineering construction etc.
Development progress reduces working efficiency.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a kind of impact resistance high-pressure rubber pipe, its object is to

Dry cylindrical protrusion portion or several hemispherical protrusions are equably arranged on the inner wall of inner glue layer, and every two is cylindric
Gap between protrusion or bulbous protrusion portion is no more than each cylindrical protrusion portion or each bulbous protrusion portion
Radius.On the one hand, outer glue-line is used using silicone sealant as weather-resistant glue, improves the cold-resistant and high temperature resistant of high-pressure rubber pipe
And anti-aging property；On the other hand, be provided on the inner wall of inner glue layer it is several it is uniform circle arrangement cylindrical protrusions or
Hemispherical protrusion, and the gap between every two cylindrical protrusion or bulbous protrusion be less than each cylindrical protrusion or
Each bulbous protrusion ensure that the density of cylindrical protrusion or bulbous protrusion is larger, and then be the high pressure of inner glue layer trickling
Liquid provides enough cushion effects, alleviates the friction and corrosion of the inner wall of highly pressurised liquid and high-pressure rubber pipe inner glue layer, Jin Erti
The high service life of high-pressure rubber pipe, and further improve using high in high-pressure rubber pipe in use, its replacement frequency can be reduced
The development efficiency of mine, oil field, the engineering construction of moulding pipe etc..The height of each cylindrical protrusion portion or hemispherical protrusion
Degree must not exceed the half of outer glue-line thickness.Cylindrical protrusion portion or hemispherical protrusion are distributed as in high-pressure rubber pipe
Continuous arrangement is only distributed at crooked position.Outer glue-line is SS511 weather proofing sealant.
Compared with prior art, the beneficial effects of the present invention are: high-pressure rubber pipe of the invention, outer glue-line and enhancement layer it
Between be provided with the objects such as mixture or sponge filled with yellow ground or yellow ground and calcium carbonate, when day heat, high-pressure glue can be reduced
Temperature in pipe, and play the role of buffering high-pressure rubber pipe, when high-pressure rubber pipe is hit or is frequently hit, Ke Yihuan
Impact force is rushed, avoiding extraneous impact force directly causes high-pressure rubber pipe explosion or glue to split；In addition, the outside of outer glue-line is additionally provided with
Several protrusions can play the role of direct anticollision from the outside of high-pressure rubber pipe, further enhance the anti-of high-pressure rubber pipe
Collision performance, and protrusion irregular alignment in outer glue-line, can not only play preferable anti-collision effect, also effectively mitigate
The quality of high-pressure rubber pipe, reduces manufacturing cost.
The present invention improves impact resistance ability, corrosion resistance and the weather resistance of high-pressure rubber pipe, and then avoids height
Moulding pipe as frequent impact when in use caused by explosion, glue split, to improve its service performance and service life, reduce
Cost.
