Description
Technical Field
The utility model relates to a high-pressure hydrogen storage tank inner container.
Background
The inner container of the existing high-pressure hydrogen storage tank is generally an aluminum inner container, and is processed by adopting a seamless aluminum tube high-temperature head shrinking process, then heat treatment and drilling. The aluminum is easy to generate hydrogen embrittlement, has low pressure resistance, heavier weight than the resin liner and complex production process.
At present, an injection molding process is adopted in Japan to produce a high-pressure hydrogen storage tank liner, the liner is made of a resin material, and the resin material has the advantages of good barrier property, light weight, long service life and the like, so that the liner is very suitable for preparing the high-pressure hydrogen storage tank liner.
SUMMERY OF THE UTILITY MODEL
The utility model provides a to the not enough of above-mentioned prior art existence, provide a high pressure hydrogen storage tank inner bag, the wall thickness is even, the compressive capacity is high, and long service life.
The utility model provides an above-mentioned technical problem's technical scheme as follows: a high-pressure hydrogen storage tank liner comprises a liner body, wherein the liner body comprises an integrally formed shell, the shell comprises a cylinder body and end sockets at two ends of the cylinder body, and the end sockets at two ends are respectively provided with a through hole; the shell is made of nylon, PE or nylon and EVOH (ethylene/vinyl alcohol copolymer) modified materials.
The utility model has the advantages that: the liner body is of an integral structure, has no splicing seam, high pressure resistance and long service life, and is not easy to crack; the shell is made of nylon or EVOH, and the weight is relatively light.
Further, the inner bag body still includes the inside lining that adheres on the shell inner wall, works as when the shell adopts nylon, the inside lining adopts PE, works as when the shell adopts PE, the inside lining adopts nylon.
The beneficial effect of adopting the further technical scheme is that: the double-layer liner has better pressure resistance and wider application range.
Furthermore, the insert is provided with a plug board for increasing the wrapping force of the shell and the insert, and the insert is provided with a connecting hole matched with the through hole.
Further, a bonding layer is arranged between the inner liner and the outer shell, and the bonding layer is formed by mutual permeation of the inner liner and the outer shell.
The beneficial effect of adopting the further technical scheme is that: under the prerequisite that the shell does not have the cooling, just add lining material, make its high temperature melt, and then adhere to on the shell inner wall, interpenetration between inside lining and the shell need not sticky, under the prerequisite of guaranteeing inner bag pressure resistance, the furthest reduces the possibility of inner bag fracture, improves the life of inner bag.
Drawings
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is an enlarged partial view of FIG. 1 at V;
in the drawings, the parts names represented by the respective reference numerals are listed as follows: 1. the device comprises a shell, 1-1 parts of an end enclosure, 1-2 parts of a cylinder, 1-3 parts of a through hole, 2 parts of a lining, 3 parts of an insert, 3-1 parts of a connecting hole, 3-2 parts of an inserting plate.
Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
As shown in fig. 1, the inner container of the high-pressure hydrogen storage tank comprises an inner container body, wherein the inner container body comprises an integrally formed shell 1, the shell 1 comprises a cylinder 1-2 and end sockets 1-1 at two ends of the cylinder 1-2, and the end sockets 1-1 at the two ends are respectively provided with a through hole 1-3; the shell 1 is made of modified materials such as nylon, PE or EVOH (ethylene/vinyl alcohol copolymer).
The inner container body further comprises an inner liner 2 adhered to the inner wall of the outer shell 1, when the outer shell 1 is made of nylon, the inner liner 2 is made of PE, and when the outer shell 1 is made of PE, the inner liner 2 is made of nylon.
The sealing head structure is characterized by further comprising an insert 3 connected with the sealing head 1-1, wherein a plugging groove is formed in the sealing head 1-1, a plugging plate 3-2 matched with the plugging groove is arranged on the insert 3, a connecting hole 3-1 matched with the through hole 1-3 is formed in the insert 3, and the connecting hole 3-1 is a threaded hole.
A bonding layer is also arranged between the inner liner 2 and the outer shell 1 and is formed by the mutual permeation of the inner liner 2 and the outer shell 1; under the prerequisite that shell 1 does not have the cooling, just add inside lining 2 material, make its high temperature melt, and then adhere to on 1 inner walls of shell, interpenetration between inside lining 2 and the shell 1 need not sticky, under the prerequisite of guaranteeing inner bag pressure resistance, the furthest reduces the possibility of inner bag fracture, improves the life of inner bag.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
