Abstract
The present invention relates to a flame-retarded heat-insulating hose, which comprises a rubber hose composed of a joint, a connecting nut, a rubber hose and a sheath of the joint, a flame-retarded layer which is made of heat-insulating materials and is wrapped outside the rubber hose, and a metal corrugated pipe covered outside the flame-retarded layer. The flame-retarded heat-insulating hose can lengthen the service life of the rubber hose, the structure is simple, and the industrial cost can be reduced.
Description
Technical field
The present invention relates to a kind of anti-flaming thermal-insulation flexible pipe, particularly a kind of anti-flaming thermal-insulation flexible pipe that is used for the rubber hose of workroom in high temperature delivery hydraulic pressure wet goods media such as smelting.
Background technique
Wait the rubber hose of workroom in high temperature delivery hydraulic pressure wet goods medium in smelting; because the temperature of surrounding environment is very high; also have molten metal or slag splashes; can cause the aging rapidly and damage of rubber pipe; existing protective measure is an anti-flaming thermal-insulation material such as looping asbestos cloth outside rubber pipe; with the steel wire asbestos cloth that is fastened; but asbestos cloth is loose easily like this; and go down for a long time; still can not avoid the damage of molten metal or slag, influence the working life of rubber hose rubber pipe.
Summary of the invention
The object of the present invention is to provide a kind of working life that prolongs rubber hose, simple in structure, and can reduce the anti-flaming thermal-insulation flexible pipe of industrial cost.
For achieving the above object, anti-flaming thermal-insulation flexible pipe of the present invention, it comprises rubber hose of being made up of joint, attaching nut, sebific duct and connection protective cap and the flame-retardant layer of making at the anti-flaming thermal-insulation material of sebific duct outside looping, metal bellows on the flame-retardant layer outer cover.
Anti-flaming thermal-insulation flexible pipe of the present invention, wherein metal bellows is the stainless steel metal bellows.
Anti-flaming thermal-insulation flexible pipe of the present invention wherein respectively welds a ring baffle at the two ends of the joint, two ends of rubber hose metal bellows, leaves the gap between described ring baffle and the rubber hose.
Anti-flaming thermal-insulation flexible pipe of the present invention is wherein at the two ends of the joint, two ends of rubber hose metal bellows difference weld metal blend stop.
Anti-flaming thermal-insulation flexible pipe of the present invention wherein has several air holes on described ring baffle.
Anti-flaming thermal-insulation flexible pipe of the present invention, owing to adopt anti-flaming thermal-insulation material outer cover metal bellows, the protection rubber pipe is not damaged, and has prolonged the working life of rubber hose; Adopt sideboard, can make the metal bellows fixed position, have several air holes on sideboard, the heat that external environment is radiated in the metal bellows can distribute from air hole.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A sectional drawing of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples in detail the present invention is described in detail.
Anti-flaming thermal-insulation flexible pipe shown in Figure 1, it comprises by joint 1, the attaching nut 2, rubber hose that sebific duct 3 and connection protective cap 8 are formed and the flame-retardant layer of making at the asbestos cloth of sebific duct 3 outside loopings 4, stainless steel metal bellows 5 on flame-retardant layer 4 outer covers, the two ends of stainless steel metal bellows 5 terminate in two end connectors, 1 place of rubber hose, a ring baffle 6 is respectively welded at two ends at two end connectors, 1 place's stainless steel metal bellows 5 of rubber hose, leave the gap between described ring baffle 6 and the joint 1, fix stainless steel metal bellows 5 with this ring baffle 6, shown in Figure 2, for the A-A sectional view of Fig. 1 is the schematic representation of ring baffle 6, have several air holes 7 on ring baffle 6, the heat that external environment is radiated in the metal bellows can distribute from air hole 7.
At steel works; for the rubber hose of hydraulic transmission delivery hydraulic pressure oil because near steel making furnace; splashing of hot environment on every side and molten metal or slag; make rubber hose be easy to aging and damage; use this anti-flaming thermal-insulation flexible pipe can protect rubber hose not to be damaged, prolong the working life of rubber hose.
This stainless steel metal bellows 5 also can replace with other metal flexible hose.
Two ends at stainless steel metal bellows 5 also can the weld metal blend stop.
This anti-flaming thermal-insulation flexible pipe is equally applicable to the protection to pipelines such as nylon tube, pitch tube, four fluorine tubes.
This anti-flaming thermal-insulation flexible pipe is applicable to that also in the pipeline of various Connecting format, internal diameter, length are not limit.
