Description

Aramid fiber woven reinforcement layer rubber hose

Technical Field

The utility model relates to a rubber hose technical field, in particular to enhancement layer rubber hose is woven to aramid fiber.

Background

The rubber hose is a steel wire woven hose. The rubber tube consists of an inner rubber layer, a steel wire braided layer and an outer rubber layer. Suitable for use in transporting hydraulic fluids such as alcohols, fuels, lubricants, emulsions, and the like. In contrast to hard tubes, flexible (rubber) tubes are most characterized by flexibility. The design of the hose varies according to the difference between the working conditions and the performance requirements, and common parameters include size, pressure, weight, length, curvature, chemical durability and the like. Compared with a hose for civil use, the industrial operation environment is more complex and harsher, and the requirement of equipment on a conveying pipe is also harsher, so that the industrial hose has strict specifications and standards from design, material selection to production, transportation and even final storage, and the hose tends to require high pressure resistance and long service life. The size of the industrial hose is wider in optional range, the pressure and temperature range is wide, and the chemical resistance is higher. The existing rubber hose has weak wear resistance and strength, and the increase of bending stress caused by large caliber can cause the outer sleeve to crack after long-term use.

Therefore, an aramid fiber braided reinforced layer rubber hose is needed to solve the problem.

SUMMERY OF THE UTILITY MODEL

To above-mentioned condition, for overcoming prior art's defect, the utility model aims at providing an enhancement layer rubber hose is woven to aramid fiber, the effectual above-mentioned problem of having solved.

The technical scheme of its solution is, the utility model discloses an by interior and outer inlayer pipe, fire-retardant layer, reinforcing tube, thermal-insulated pipe and the outer pipe that sets gradually, the reinforcing tube includes that the equipartition has the support pipe wall of a plurality of recesses on the lateral wall, installs the telescopic link in the recess, and the tip of telescopic link is equipped with the arc roof, still overlaps on the telescopic link and is equipped with the spring, the one end mounting groove's of spring bottom, the other end of spring is installed on the arc roof, outer intraductal a plurality of chambeies of moving away to avoid possible earthquakes that are equipped with.

The utility model has the advantages that: the utility model has the advantages of ingenious structure, novel conception, compact structure, reasonable design, strong practicability, high pressure resistance, tensile resistance, longer service life, durability, wear resistance, firmness and durability, adopts the shockproof sleeve, lightens the pressure and the shock sensation from the ground, and further prolongs the service life of the pipe body; the adopted shock-proof cavity is a trapezoidal cavity, so that a good compression-resistant effect is achieved, the phenomena of distortion and bending are effectively prevented, the use is convenient, the air circulation is smooth, and the working efficiency is improved.
