Abstract
The utility model discloses a kind of combustion gas corrugated flexible hose, and comprise bellows, PE pipe and joint, described PE pipe is positioned at bellows outside, and described bellows one end is connected with joint by screw thread, and the other end connects a flange, is embedded with wire netting at described PE pipe.Its quality is light, cost-saving, can antioxidant anticorrosive and good toughness, effectively improve the working life of combustion gas corrugated flexible hose.
Description
Technical field
The utility model relates to a kind of combustion gas delivering pipe, is specifically related to a kind of combustion gas corrugated flexible hose.
Background technique
Combustion gas is a class calorific value high, clean low stain, safety and stability, cheap gaseous fuel, is thus extensively praised highly, but due to combustion gas be inflammable gas, easy leakage, meet fire namely to fire, have danger, the conveyance conduit therefore for combustion gas requires also stricter.
Corrugated flexible hose is a kind of combustion gas transmission pipeline common in routine use, it is a kind of flexible pipe, current corrugated flexible hose mostly be bellows, protecting cover and connecting head three part form, bellows is often made with stainless steel, protecting cover is that Stainless Steel Wire or steel band braiding form, because bellows metal and atmospheric oxygen oxidation reaction can occur, and the corrosion of gaseous impurity in pipeline in combustion gas, reduce bellows working life.The protecting cover of corrugated flexible hose is main compression-member, makes corrugated flexible hose have certain bearing capacity, and metal protection cover can effective external force resistance but cause certain waste to material, there is a class PE protecting cover at present, it is light, with low cost, but shock proof insufficient strength, Security is not high.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of combustion gas corrugated flexible hose, and its quality is light, cost-saving, can antioxidant anticorrosive and intensity is high, effectively improves Security and the working life of combustion gas corrugated flexible hose.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of combustion gas corrugated flexible hose, comprise bellows, PE pipe and joint, described PE pipe is positioned at bellows outside, and described bellows one end is connected with joint by screw thread, and the other end is provided with a flange, in described PE pipe, be also embedded with wire netting.
Described bellows is made up of the stainless steel adding 10.5% chromium.
Described flange is provided with joint the annular groove mated with PE pipe in the side be connected with bellows.
Rubber seal is provided with in described annular groove.
The beneficial effects of the utility model are:
1) bellows outside adopts the PE pipe embedding wire netting, can also add the intensity of PE pipe, protect inner bellows from the infringement of external impact while saving metallic material;
2) by the setting to annular groove, the position of PE pipe can be fixed, rubber seal is set in annular groove PE can be made to manage and the joint at two ends and flange close contact, improve the tightness of bellows, the combustion gas avoiding bellows breakage to reveal afterwards enters in air, reduces potential safety hazard;
3) bellows adopts the stainless steel of interpolation 10.5% chromium to make, and can prevent the oxidized corrosion of bellows to a greater extent, improves working life and the Security of bellows.

Fig. 3 is the utility model flange side schematic view;
Fig. 4 is the utility model joint side schematic view.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As depicted in figs. 1 and 2, a kind of combustion gas corrugated flexible hose, comprise bellows 1, PE pipe 2 and joint 3, PE pipe 2 and be positioned at bellows 1 outside, bellows 1 one end is connected with joint 3 by screw thread, and the other end also connects a flange 4, is embedded in wire netting 5 at PE pipe 2.
Wherein bellows 1 is made up of the stainless steel of interpolation 10.5% chromium.
As shown in Figure 3-4, joint 3 and flange 4 are provided with the annular groove 6 mated with PE pipe 2 in the side connected with bellows 1, be provided with rubber seal 7 in annular groove 6.
More than show and describe basic principle of the present utility model, major character and advantage.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
