Abstract
An embodiment of the utility model discloses a gas pipe, which comprises an inner flame-retardant layer and an outer ageing-resistant cold-resistant layer. A wire sandwich layer is arranged between the inner flame-retardant layer and the outer ageing-resistant cold-resistant layer. The inner flame-retardant layer does not react with chemical substances in components of gas, and is flame-retardant. The outer ageing-resistant cold-resistant layer is ageing-resistant and cold-resistant. Therefore, the gas pipe is ageing-resistant and cold-resistant, while ageing is prevented. Further, the wire sandwich layer is arranged between the inner flame-retardant layer and the outer ageing-resistant cold-resistant layer, pressure resistance of the gas pipe is improved, strength of the gas pipe is enhanced, the inner flame-retardant layer and the outer ageing-resistant cold-resistant layer are fixed, and thereby the gas pipe has the advantages of safety and the like.

Technical field
The utility model relates to the conveyance conduit technical field, more particularly, relates to a kind of combustion gas with managing.
Background technique
People need be connected kitchen range with pneumatic tube when using gas range with origin.At present, the pneumatic tube of a lot of combustion gas users uses is non-combustion gas pipes, and for example water pipe replaces combustion gas with managing use, because characteristics such as it is fire-retardant that water pipe does not possess that the combustion gas sebific duct has, therefore, phenomenons such as gas leakage taking place easily, easily causes accidents such as economic loss and casualties; In addition, the composition of some flexible pipes can react with the chemical substance in the contained composition of combustion gas on the market, therefore, during with pipe, easily causing flexible pipe emulsification gas leakage as combustion gas, can lead to major accidents such as casualties.
Combustion gas pipe commonly used at present is a rubber pipe.Because the chemical substance that rubber pipe is not easy in the contained composition of combustion gas reacts, therefore, often be used to combustion gas at present with managing.But rubber pipe is easily aging, and working life is short, and gas leak phenomenon takes place easily, has very big potential safety hazard.For example, application number is a kind of gas cooker special-purpose flexible pipe that connects that 02219284.0 Chinese patent literature has been reported, this flexible pipe is a rubber pipe, and the company's section that connects at the source of the gas of rubber pipe and kitchen range is divided into and is provided with threaded coupling, is provided with gasket seal in the inipple.The rubber pipe of this structure has been avoided coming off of rubber pipe to a certain extent, thereby has avoided the gas safe accident that causes because of coming off.But under high temperature and low temperature, the easily aging and be full of cracks of this rubber pipe, tolerance to cold is relatively poor, and this rubber pipe is a single layer structure, therefore, when gaseous-pressure is excessive, phenomenons such as modification takes place easily, and anti-pressure ability is relatively poor.
The model utility content
In view of this, the technical problems to be solved in the utility model is to provide a kind of combustion gas with managing, and this combustion gas has cold-resistant preferably, anti-aging and anti-pressure ability with pipe.
The utility model provides a kind of combustion gas with managing, and comprising:
Fire-retardant internal layer and ageing-resistant cold-resistant skin are provided with the clamp layer between described fire-retardant internal layer and the described ageing-resistant cold-resistant skin.
Preferably, described clamp layer is a nylon wire.
Preferably, described fire-retardant internal layer is the fire-retardant internal layer of PVC.
Preferably, described ageing-resistant cold-resistant skin is the ageing-resistant cold-resistant skin of PVC.
Preferably, the internal diameter of described fire-retardant internal layer is 6～10mm.
Preferably, the internal diameter of described fire-retardant internal layer is 7～9mm.
Preferably, ageing-resistant cold-resistant outer field external diameter is 12～16mm.
Preferably, ageing-resistant cold-resistant outer field external diameter is 13～15mm.
From above-mentioned technological scheme as can be seen, the utility model provides a kind of combustion gas with pipe, comprises fire-retardant internal layer and ageing-resistant cold-resistant skin, is provided with the clamp layer between described fire-retardant internal layer and the described ageing-resistant cold-resistant skin.Fire-retardant internal layer not with the contained composition of combustion gas in chemical substance react, have fire-retardant effect; Ageing-resistant cold-resistant skin is owing to have ageing-resistant cold-resistant effect, and therefore, the combustion gas that the utility model provides has ageing-resistant cold-resistant effect with pipe, has prevented aging.And the utility model is provided with the clamp layer between fire-retardant internal layer and ageing-resistant cold-resistant skin, has improved the anti-pressure ability of combustion gas usefulness pipe, has strengthened the intensity of combustion gas with pipe, and has fixed fire-retardant internal layer and ageing-resistant cold-resistant skin, thereby had advantages such as safe.
