Abstract
The utility model discloses a natural gas composite material gas bottle. The natural gas composite material gas bottle solves the problems that a natural gas bottle is easy to corrode, is poor in safety and is not easy to place and fix in the prior art. The natural gas composite material gas bottle comprises an inner container made of high density polyester plastics and a composite fiber layer winding the outer wall of the inner container, wherein saddles are arranged on the composite fiber layer, grooves matched with the outer wall of the composite fiber layer are arranged in the saddles, and the number of the saddles is two. The natural gas composite material gas bottle has the advantages of being light in weight, high in capacity ratio, good in gas tightness, high in fatigue life, convenient to place and fix, low in cost and the like.
Description
Technical field
The utility model relates to compressed natural gas cylinder, particularly a kind of rock gas composites gas cylinder.
Background technique
At present, steel gas cylinder is to use early and widely used a kind of gas cylinder, can be divided into again from the manufacturing process of steel gas cylinder and to rush bottle moving and glass tube vial, the advantage of steel gas cylinder is that preparation process is simple, price is low, but the shortcomings such as volume to weight ratio is high, perishable, poor stability are also arranged, and this steel gas cylinder is difficult for laying and fixing.
The model utility content
The purpose of this utility model is to provide a kind of rock gas composites gas cylinder, solves that natural gas cylinder of the prior art is perishable, poor stability and be difficult for the problem of laying and fixing.
To achieve these goals, the technical solution adopted in the utility model is as follows:
The rock gas composites gas cylinder comprises the inner bag that is formed by the polyester of high density plastic production, is wound in the composite fibre layer of this inner bladder outer wall; Be provided with saddle on the described composite fibre layer outer wall.
Further, described saddle is provided with the groove that is complementary with the composite fibre layer outer wall, and saddle is two.
Again further, described composite fibre layer outer surface also is provided with the protective layer that is made by polyurethane.
Further, place, described inner bag air outlet is provided with by the coupled metal flange of screw thread.
In addition, described saddle is the trapezoid body shape, and described groove is arranged at the upper surface of saddle.
Compared with prior art, the utlity model has following advantage and beneficial effect:
(1) inner bag and composite fibre layer are all selected the material of expansion coefficient mismatching in the utility model, and adopt the structural design of optimizing, and prevent that effectively internal and external layer from coming off, bulge;
(2) composite fibre layer of the present utility model adopts a large amount of fibers, fiber on every square centimeter reaches several thousand, several ten thousand, when composite cylinder overloads and a small amount of fiber breakage occurs, its load can be redistributed rapidly on unbroken fiber, this does not cause gas cylinder forfeiture bearing capacity in short-term and even in the quite a long time, so its durability is significantly improved;
(3) the utlity model has good bearing capacity, sealing, corrosivity and Security, when the optimum drive of taking for the user is experienced, effectively reduced energy consumption and cost; The more important thing is, even in case gas bottle explosion occurs, the utility model can not produce any fragment yet, allows the user no longer include a back of the body gas cylinder just such as the fear of the back of the body " bomb flows ", so can make gas cylinder described in the utility model become the best substitute of gas-fueled vehicles metal gas cylinder;
(4) the utility model is provided with saddle, is conducive to laying and fixing of rock gas composite cylinder;
(5) the utility model is simple in structure, and is with low cost, is easy to promote the use of.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is place, inner bag air outlet enlarged diagram in the utility model.
Wherein, the component name that mark is corresponding in the accompanying drawing is called: 1-inner bag, 2-composite fibre layer, 3-saddle, 4-protective layer, 5-metal flange.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, and mode of execution of the present utility model includes but not limited to the following example.
Embodiment
As shown in Figure 1, 2, the rock gas composites gas cylinder comprises the inner bag 1 that is formed by the polyester of high density plastic production, is wound in the composite fibre layer 2 of this inner bag 1 outer wall, and is arranged at the protective layer 4 that these composite fibre layer 2 outer surfaces are made by polyurethane; Also be provided with on the described protective layer outer wall and be convenient to the saddle 3 that the utility model is laid and fixed; And described inner bag 1 air outlet also is provided with the metal flange 5 that is connected with inner bag by screw thread, and this metal flange is between inner bag and composite fibre layer.
Above-mentioned saddle 3 is provided with the groove that is complementary with the protective layer outer wall, and saddle 3 is two; This saddle 3 is the trapezoid body shape, and described groove is arranged at the upper surface of saddle.
The composite fibre layer of the present embodiment is made by carbon fiber and glass fibre, and this composite fiber layer thickness is 4.5mm, and the angle that this composite fiber hoop twines is 70 °.
The shoulder breadth ratio of described metal flange is 1.5, and its external surface is consistent with the external surface curvilinear equation at place, inner bag air outlet, and its interior shape face thickness from the neck root to the shoulder breadth edge is attenuate gradually.
According to above-described embodiment, just can realize well the utility model.
