Abstract

The utility model relates to an annular pressure container with a fibre coiled composite material rubber liner. The inner surface of the annular pressure container 1 is provided with a rubber liner 2, a coiled structure layer 4 made from the fiber 3 coiled composite material is arranged outside the rubber liner, the annular pressure container 1 is provided with one joint 5 for media in and out at least, and the section of the annular pressure container is round or elliptic. The utility model has the advantages of light weight, low manufacturing cost, short production cycle, stable quality, good fatigue resistance, etc. The utility model solves the problem that a metallic vessel is easily destroyed in low pressure by the existing tiny defects and does not generate large quantity of antipersonnel fragments even the pressure container is ruined.

Description

Pressure container with wound composite fiber material and rubber liner

The utility model belongs to a kind of toroidal pressure vessel.

Aeronautics and Astronautics and military field widespread demand toroidal pressure vessel, but because its structural feature is more special, traditional construction of pressure vessel material mainly is a metallic material.In manufacturing process, exist shortcomings such as quality of product is big, manufacture cost is high, the manufacture cycle is long, poor stability.And in a single day metal pressure container exists tiny flaw that the low pressure breakoff phenomenon can take place, and easily generation can lethal fragment, causes casualty accident.And can not reach Aeronautics and Astronautics and military field to its performance demands with the toroidal pressure vessel that other any single nonmetallic material are made.

The purpose of this utility model is a kind of pressure container with wound composite fiber material and rubber liner of design.This toroidal pressure vessel is organically combined by two kinds of nonmetallic material and makes.It should have product structure rationally, characteristics such as lighter weight, low cost of manufacture, with short production cycle, constant product quality.It also should solve canister and has tiny flaw and the low pressure breakoff phenomenon takes place, and produces the problem of a large amount of lethal fragments.

The purpose of this utility model realizes in the following manner: the internal surface of toroidal pressure vessel 1 is a rubber material inside liner 2, the construction layer 4 that intrinsic fiber 3 wound composites are made on the outside of rubber material inside liner 2, on toroidal pressure vessel 1, be provided with at least one medium turnover joint 5, be connected inside and outside joint 5 and the toroidal pressure vessel 1.

The rubber material inside liner 2 of the utility model toroidal pressure vessel 1 internal surface seals; The construction layer 4 that outer fiber 3 wound composites are made works to bear pressure.So it has product structure structure, light weight, low cost of manufacture, with short production cycle, advantage such as mass stability is high, fatigue performance is good.It has also solved canister and has had tiny flaw and the problem that low pressure is destroyed takes place.Even damaging, this container can not produce a large amount of lethal fragments yet.

Fig. 1 is a plan view of the present utility model, and Fig. 2 is the plan view of Fig. 1, and Fig. 3 is embodiment two a plan view.

Embodiment one: the cross section of the toroidal pressure vessel 1 of present embodiment is circular.The internal surface of toroidal pressure vessel 1 is a rubber material inside liner 2, the outside of rubber material inside liner 2 is winding structure layers 4 that intrinsic fiber 3 wound composites are made, on toroidal pressure vessel 1, be provided with two media turnover joints 5, be connected inside and outside joint 5 and the toroidal pressure vessel 1.

Embodiment two: present embodiment and embodiment one are different is that the cross section of toroidal pressure vessel 1 is for oval.Other composition is identical with embodiment one with annexation.
