Abstract
The utility model discloses a household fuel gas rubber tube which is used for connecting a natural gas household main pipeline with a gas cooker. The cross section of a tube body adopts a round structure; the tube body adopts a three-layer compound structure which is formed by tightly bonding an inner layer which is resistant to gas corrosion, an intermediate layer with enhanced elasticity and an outer layer having a protective effect; and the inner layer is rubber with corrosion resistance and gas tightness, the intermediate layer is elastic and anti-deformation rubber, the outer layer is antioxidant rubber, and polarities of the three layers of rubber are similar. The household fuel gas rubber tube solves the technical problems that the conventional tube is prone to corrosion and aging.
Description
Technical field
The utility model relates to a kind of rubber fuel tube of the flexible pipe that is connected with household gas utensils, particularly a kind of composite structure.
Background technique
After natural gas line delivers into user terminal, generally to link through flexible pipe and by metal permanent joint and gas range.Existing flexible pipe has various material and structure, modal is polyvinyl chloride hose, and this flexible pipe generally has only 2 years its service life, and using for a long time easily, ageing hardening becomes fragile even ftractures gas leakage, because PVC flexible pipe flame retardant property is poor, run into the naked light initiation fire that burns easily.Take place for fear of the problems referred to above, the double-deck flexible pipe of employing is also arranged, as adopting General Purpose Rubber as flexible pipe internal layer matrix, General Purpose Rubber can be corroded in use for some time and further cause deterioration phenomenon, and influence is used.
The model utility content
The purpose of this utility model provides a kind of domestic gas rubber pipe, solve existing flexible pipe technical problem perishable, that easily wear out.
For achieving the above object, the utility model adopts following technological scheme:
A kind of domestic gas rubber pipe; the rounded structure of its body cross section; described body is the internal layer that corroded by the gasproof body, strengthen flexible middle level and three-layer composite structure that the outer closely adhesion that shields forms; described internal layer, be anticorrosive, tightness rubber; the middle level is elastic reactance distortion rubber; skin is anti-oxidant rubber, three layers of rubber electrodes similar temperament.
Described internal layer can be the synthetic rubber of chlorohydrin rubber or nitrile butadiene rubber/chlorohydrin rubber blend.
Described skin can be neoprene or the compound sizing material of haloflex;
Described middle level can be nitrile butadiene rubber;
The thickening in gradient successively of the internal layer of described body, middle level and outer order.
Described internal layer, middle level and outer field thickness are between the 1mm-2mm, and above-mentioned three layers thickness summation is between 2.5-4.5mm, and the nominal outside diameter of described body is not more than 13mm.
Compared with prior art the utlity model has following characteristics and beneficial effect:
Scientific structure design of the present utility model, simple, long service life, tightness is good, the Safety performance height.Internal layer of the present utility model, middle level and outer field thickness are between the 1mm-2mm, the thickening in gradient successively of internal layer, middle level and outer order, above-mentioned three layers thickness summation is within 2.5-4.5mm, when the accurate control of thickness can guarantee combustion gas rubber pipe free bend without any the slit, thereby reach the requirement of elasticity and the sealing of use, can make the various bending deflections in use of three layer sizings and layer and the separating of layer do not occur.
Internal layer of the present utility model is made of the chlorohydrin rubber of medium-resistance excellence, has anticorrosive and the good airproof performance characteristic, is applicable to the characteristics of the corrosion of various combustion gas media; Its middle level is attached on the internal layer, is made of the nitrile butadiene rubber of comprehensive good physical performance, has performances such as the resiliently deformable of reinforcement; Its skin is attached to above the middle level, has crust protection and oxidation resistant effect, and sizing material has higher intensity, toughness, flame retardancy and ageing-resistant performance.
Description of drawings
The utility model is described in more detail below in conjunction with accompanying drawing.
Fig. 1 is cross sectional representation of the present utility model.
Fig. 2 is the schematic representation of the utility model oblique profile.
Reference character: 1-internal layer, 2-middle level, 3-skin.
Embodiment
Referring to Fig. 1, Fig. 2; the utility model is a kind of domestic gas rubber pipe that connects between natural gas in home house lead in main pipe and the gas range; the rounded structure of its body cross section; described body is the internal layer 1 that corroded by the gasproof body, strengthen flexible middle level 2 and three-layer composite structure that the skin 3 tight adhesions that shield form; described internal layer 1, be anticorrosive, tightness rubber; middle level 2 is elastic reactance distortion rubber, and outer 3 is anti-oxidant rubber, three layers of rubber electrodes similar temperament.
Described internal layer 1 can be the synthetic rubber of chlorohydrin rubber or nitrile butadiene rubber/chlorohydrin rubber blend.
Described outer 3 can be neoprene or the compound sizing material of haloflex.
Described middle level 2 can be nitrile butadiene rubber.
The internal layer 1 of described body, middle level 2 and the thickening in gradient successively of outer 3 orders.
The thickness of described internal layer 1, middle level 2 and skin 3 is between the 1mm-2mm, above-mentioned three layers thickness summation is between 2.5-4.5mm, the nominal outside diameter of described body is not more than 13mm, have in that aging-resistant is simultaneously anti-and subdue crooked function, can make the various bending deflections in use of three layer sizings and separating of layer and layer do not occur.
The above mode of execution; it only is the more representational embodiment of the utility model; but the utility model institute resist technology scheme is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; can all should be encompassed within the protection domain of the present utility model from direct all changes or the replacement of deriving or expecting easily of the disclosed content of the utility model.
