Abstract
A locomotive metal or rubber hose includes a pipe and a withholding component and the pipe compriseswoven stainless steel wires. The internal and external sleeves of the withholding component are connected by threads and clamped at the port of the hose together and the clamping surface is disposed with corresponding taper and anti-sliding mechanism. The utility model is applicable to oil transfer line under strong vibration and comparatively high oil pressure, especially to mobile oil and fuel pipeline system for DF-style locomotive; the utility model has excellent anti-pressure and anti-shock performances. Moreover, the utility model is convenient to assemble and dismantle with a long service life and the utility model overcomes the obvious defect that the present metal or rubber hoses used for locomotive are easy to be damaged and difficult to be mounted.
Description
Technical field
The utility model relates to a kind of transport pipe, especially for the antidetonation of locomotive pipe-line system, withstand voltage metal-rubber composite soft tube.
Background technique
The machine oil of engine, particularly DF type locomotive, the transport pipe in the fuel piping system are general at present to adopt steel pipe, or metallic hose, or rubber hose.Steel pipe is shaken easy damage, and difficulty is installed; Metallic hose is tired easily and ftracture under the pulse of machine oil, fuel oil and dither state, and particularly the buckling piece at body two ends adopts welding type to connect usually, because tube wall is thinner, more is subject to vibrations and draws bad.The rubber hose withstand voltage properties is relatively poor, explosion easily under the pulse of machine oil, fuel oil and dither state.Therefore present several transport pipe all respectively have deficiency.
Summary of the invention
The purpose of this utility model is to overcome the defective that present transport pipe is fragile, installing/dismounting is difficult, provide a kind of withstand voltage, anti-seismic performance good, easy installation and removal, the locomotive metal sebific duct of long service life.
The technical solution of the utility model is: locomotive metal sebific duct comprises body and is assemblied in the assembly of withholding at body two ends, improvements are described bodys by rubber pipe and are wrapped in the outer field Stainless Steel Wire mesh grid of rubber pipe and constitute, the described assembly of withholding comprises inner sleeve, outer sleeve and attaching nut, inside and outside sleeve pipe is by being threaded, be clamped in the port position of body jointly, the gripping surface of inside and outside sleeve pipe has corresponding tapering and anti-slip mechanism is arranged.
Further, described attaching nut pine is enclosed within the boss inboard of inner sleeve; Described anti-slip mechanism is provided in a side of the inner sleeve outside and outer sleeve inboard, cross section indentation and crown antislip ring inwards; Described antislip ring is circular or helical.
Adopt above technological scheme, since the toughness and the good springiness of rubber pipe, the energy antidetonation, its outer parcel one deck Stainless Steel Cloth then improves withstand voltage properties greatly, and the peculiar design of two ends buckling piece in addition connects reliable, easy to operate, not fragile.Therefore the utility model combines the advantage of metallic hose and rubber hose, and keeps away its deficiency, and is withstand voltage, anti-seismic performance good, easy installation and removal, and long service life is particularly useful for DF type locomotive machine oil, fuel piping system.
