Description
Technical field
The utility model relates to a kind of high-pressure bottle, particularly relates to a kind of composite cylinder.
Background technique
Gas cylinder is in order to store and transport Permanent gas, liquid gas and dissolved gas disposable or portable pressurized container that can repeated inflation, safety problem is the major issue that gas cylinder is produced and used, therefore, relevant international standard, such as ISO11119, ISO11120 etc. are put into effect for gas cylinder.Conventional gas cylinder in industry, all adopt high strength alloy seamless steel pipe as raw material, process through two ends mould pressing, overall quenching with Subsequent tempering, processing whorl of bottleneck, removing inner and outer surface corrosion thing, nondestructive inspection, thickness measuring, outer anticorrosive coating, the operations such as pressurize that overflow.In addition, also need further to carry out strict quality control and inspection measure, guarantee reaches the requirement of relevant international standard like this.Thereby the manufacture cost of this type of gas cylinder is high, conduct oneself with dignity also larger.
In order to reduce the quality of gas cylinder, increase gas cylinder intensity simultaneously, in the prior art, also have a kind of middle-size and small-size gas cylinder of glass reinforced plastic winding structure, be wound around the mixture of glass fibre and epoxy resin at steel cylinder skin, thereby formed a protective layer shell.This can form reinforcement and protection to a certain degree to cylinder liner, can cushion the explosion of inner bag.This gas cylinder, than lightweight with isometric overall structure gas cylinder, has been applied to the gas container of Natural gas vehicles; More senior gas cylinder is to be wound around carbon fibre resin at the outer surface of high tensile aluminium alloy inner bag or high strength plastic liner, forms the protective layer that weight is lighter, intensity is larger, can bear higher working pressure, and this type of gas cylinder does not apply prestressing force yet.But through this type of process treatment process complexity, equipment cost and cost of material are very high, the cost of the gas cylinder of manufacture is extremely expensive.
But no matter be common steel cylinder or composite cylinder, because bottle or glass liner are in forming process, metal is stretched or is pushed, and can form tiny crack, be filled with after gas, gas can enter these tiny air clefts, because the air pressure in gas cylinder is very high, long-time time after, crack can be large by gas support, reduce gas cylinder compressive strength, can only improve by increasing the thickness of gas cylinder at present the safety coefficient of gas cylinder, be unfavorable for the lightweight of gas cylinder.
Model utility content
The utility model provides a kind of composite cylinder, simple in structure, lightweight, has good compressive strength simultaneously.
A kind of composite cylinder, comprises that outer wall is wound with the glass liner of fabric reinforcement, and glass liner comprises the courage body and the bottle neck that are interconnected, and bottle neck place is sealed with cylinder valve, and the inwall of described courage body is coated with innerliner, and the thickness of described innerliner is 0.75mm～1.50mm.
Composite cylinder of the present utility model, cover innerliner by the inwall at courage body, innerliner is opened isolated the fine cracks on the gas in gas cylinder and courage body inwall, make gas can not enter crack, thereby avoid gas cylinder in long-time using process, the problem that the long-term punching press of pressurized gas crack causes crack to increase, in substantially not increasing gas cylinder weight, effectively improves the compressive strength of gas cylinder.
For convenient this innerliner of coating, preferred, the material of described innerliner is resin.Such as unsaturated resin or epoxy resin etc., can utilize prior art to spray or roller coating, and impose corresponding condition and be cured, and resin has good tightness.
In order to improve the compressive strength of gas cylinder entirety, preferred, described innerliner extends to the inwall of bottle neck.Because the sealing configuration operated by rotary motion of gas cylinder is in bottle neck position, the therefore inwall of pressurized gas cover part bottle neck, the inwall that innerliner extends to bottle neck can increase the useful area of coated pressurized gas.
In order to improve the sealing of gas cylinder entirety, make innerliner cover all pressurized gas simultaneously, further preferred, described cylinder valve comprises and is positioned at the valve body of bottle neck outside and communicates with valve body and stretch into the suction tude of bottle neck, and the outer wall of suction tude and the extension of described innerliner are sealed and matched.The sealed fitted seal of pressurized gas is in gas cylinder, thereby the position in being sealed and matched has all covered innerliner, completely coated all pressurized gas.
The mode of sealing gas is a lot, installs for convenient, further preferred, between the outer wall of suction tude and the extension of described innerliner, is provided with seal ring.
The extension part branch of innerliner increases the inner wall thickness of bottle neck, form ledge structure, can cause like this suction tude in the time coordinating with extension, scratch extension, because the general quality of gastight material is softer, easily scratched and come off or damage, therefore, preferably, described bottle neck is being provided with circular groove near on the inwall of courage body one side, and the extension of described innerliner is filled in this circular groove.By circular groove is set; forming towards a side of courage body the protection step being connected with extension; the thickness of described extension flushes with protection step or a little less than protection step, avoids suction tude to stretch into while being transitioned into extension along bottle neck inwall, and extension is scratched.
Because the edge of extension easily comes off, further preferred, described circular groove is being provided with the deepened section radially extending out away from one end of courage body, and the edge of described extension turns up and is filled in this deepened section.The edge of extension is positioned at circular groove in the one end away from courage body, and outwards turnover is filled in this deepened section, has improved the adhesion at edge, makes edge difficult drop-off.
Preferably, described bottle neck is away from the extension smooth transition of inwall and the innerliner of courage body one side.Arrange like this can make suction tude insert bottle neck time, sealing configuration enters extension smoothly, prevents that sealing configuration and extension from mutually scratching and damaging.
Further preferred, the inwall of described extension is mutually concordant with the inwall of bottle neck, thereby makes the transition of inwall of extension and bottle neck more level and smooth, the assembling of the sealing configuration of being more convenient for.
The beneficial effects of the utility model:
Composite cylinder of the present utility model, covers innerliner by the inwall at courage body, thereby prevents that filling pressurized gas from entering in the fine gap of courage body, improves the compressive strength of gas cylinder, extends the working life of gas cylinder.
