Abstract
The utility model relates to a special nylon flexible pipe assembly, belonging to a fluid conducting tool. The utility model is composed of a pipe body and a buckled joint, wherein, the pipe body is composed of an inner nylon pipe, an enhanced layer with steel wires and an outer protective mark made of red resin, and the annular inner wall cogs are sheathed out of the buckled joint. Since structure and materials selected reasonably, the utility model has simple preparing process, low cost and the performances of acetylene resistance, acetylene diffusion prevention, aging resistance, electric conduction, etc., and the safety factor of voltage resistance is more than 3.5 times. Production and personal safety in acetylene melting industry are ensured.
Description
The utility model belongs to fluid transporting instrument, particularly a kind of dissolved acetylene special high-pressure transporting instrument.
The ignition energy of dissolved acetylene and all very low naturally is inflammable and explosive inflammable gas.Filling of its transporting and gas cylinder is a big key of keeping the safety in production in the Dissolved Acetylene Industry.At present, Dissolved Acetylene Industry has had special-purpose sebific duct, " the special-purpose hose assembly of dissolved acetylene " as No. 86210012 utility model patents elaborations of China, technical problems such as media-resistant, withstand voltage, conduction have been solved, production technology is complicated, cost is higher, ageing-resistant performance is not ideal enough but exist, and the long-term outer glue-line color and luster in back that uses is seriously polluted and owing to the slow diffusion of acetylene gas in rubber has disadvantages such as bubbling and blasting phenomena during glue-line outside causing.
The purpose of this utility model provides a kind of both anti-acetylene, medium-acetone, can derive static, high pressure resistantly simplifies production technology again, reduce cost, improve outer protective emblem layer ageing-resistant performance, reduce pollute, rubber hose assembly beautiful in colour.
The utility model is achieved in that this assembly parts comprises body and fastening-pressing type joint, and its middle tube body is made up of pipe, steel wire enhancement layer, red resin class, outer protective emblem layer in the nylon, and the joint overcoat of fastening-pressing type joint has the inwall annular tooth.Its working process is as follows: braided steel wire enhancement layer outside the pipe in nylon, coat the outer protective emblem layer of red resin class then, and finish body and make.The flexible pipe of intercepting fixed length embeds steel joint overcoat and joint core bar at its two ends.The adjustment amount of withholding is withheld the joint overcoat, makes its inwall annular tooth penetrate outer protective emblem layer and is pressed on securely on the steel wire enhancement layer.Lock on core bar with coupling nut external again.Finished the making of dissolved acetylene special-purpose nylon rubber hose assembly with this.
The utility model is owing to select for use nylon tube as inner tube material, and the anti-diffusion, the ageing-resistant performance that have improved acetylene gas reach interior pipe self to resistance to pressure; After braided steel wire strengthened, the withstand voltage properties of body obviously improved, and safety coefficient is up to more than 35 times, and bursting pressure reaches more than the 90MPa; The inwall annular tooth of steel joint overcoat directly firmly contacts with body steel wire enhancement layer can reach conductive effect; Outer protective emblem layer adopts the red resin material, has improved ageing-resistant performance and has made color and luster more gorgeous.The production and the personal safety of Dissolved Acetylene Industry are ensured.
Fig. 1 is a kind of concrete structure schematic representation of the present utility model.
Among the figure: the 1-coupling nut; 2-joint core bar; 3-joint overcoat; 4-inwall annular tooth; The outer protective emblem layer of 5-; 6-steel wire enhancement layer; Pipe in the 7-nylon.
Below in conjunction with this structure of description of drawings tool of the present utility model.
In nylon, outside the pipe, implement steel wire enhancement layer 6 with φ 0.3mm steel wire; After coating red polychloroethylene with high polymerization degree protective emblem layer 5, by usage requirement intercepting fixed length; The nested joint overcoat 3 and insert core bar 2 at the flexible pipe two ends is withheld joint overcoat 3 and is realized that inwall annular tooth 4 penetrate outer protective emblem layer 5 and are pressed on securely on the steel wire enhancement layer 6; Lock on pin head 2 with coupling nut 1 external again.Promptly constitute dissolved acetylene special-purpose nylon rubber hose assembly.
