Abstract

The utility model relates to a multilayer composite high-pressure gas cylinder, belonging to the gas pressure vessel made of winding steel material, enhanced integral tensile ability. The high-pressure gas cylinder uses a replaceable mobile type antiseptic rubber as an inner liner, a cylinder body is compounded and solidified by that an arc-shaped tooth anchor ear which is sheathed with a copper end head winds vertical line layer wire cables, lateral line layer wire cables, and three layers of mixed fiber alternately isolated with the two layers of the wire cables. The utility model has the advantages of simple construction technology, easy manufacture, economical and practical structure, and great popularization value.

Description

Multi-layer combined gas cylinder

The utility model relates to barochamber a kind of splendid attire compression or liquefaction, particularly strengthens the barochamber of whole resistance to tension by twining rigid material.

China patent ZL90212336.X has proposed a kind of " not having dark circumferential weld multilayer HP (high pressure) vessel " that the dark circumferential weld ladder of two ends is distributed to each layer and multilayer rigidity cylindrical shell ladder is staggered and welds, this structure and traditional cold-extruded, cold pressing or cold revolve make individual layer heavy wall high-pressure bottle compare, have significantly different, but have same wall thickness heaviness, increase cost of production and transportation, deficiency that cost of use is high.China patent ZL91110861.0 has proposed a kind of " multilayer spirally wound high pressure vessel that is used for deep cooling low temperature " that is welded at successively interlock than tube outer surface in thin winding flat steel band of multilayer and steel band two ends on the simplified end chamfer at said structure, this scheme is compared with said structure, work simplification, weight reduce, but existing all steel system structure is carried inconvenient problem and existed all the time.For this reason, China patent ZL942232003 has proposed a kind of employing lightweight material compounded " lightweight composite cylinder " with steel mesh cover and rigidity anchor ear, but this gas cylinder not only has good impact toughness, rigidity intensity and extremely strong ends the quick-fried effect of splitting, and has also solved transportation simultaneously preferably and has used problems such as light and corrosion-resistant.

The purpose of this utility model on original design " lightweight composite cylinder " patent basis, further solves the steel mesh cover and proposes a kind of follow-on multi-layer combined gas cylinder with rigidity anchor ear problem.

Technical solution of the present utility model is: general structure is still by valve protection cap, cylinder valve, bottle, glass liner, composition glass liners such as neck ring adopt has the antiseptic rubber of tension force to make, and be adhered on the steel termination by valve place packing ring, cylinder valve passes through the suction port scyewed joint on the neck ring internal thread, bottle internal layer two ends are located by the steel termination, and middle room forms inner shell with the blend fiber composite curing, the two-layer arc tooth anchor ear that adopts separation layer to disconnect through the termination suit twines vertical line layer wire rope and perpendicular horizontal line layer wire rope respectively again, and separation layer between two-layer wire rope and outer surface layer constitute by the mixed fibre composite curing, constitute the sticking canvas layer of isolating glass liner that is associated with of inner layer surface of bottle.

Multi-layer combined gas cylinder according to the such scheme manufacturing, the advantage that has not only kept original design " lightweight composite cylinder ", and solved the too big and rigidity of High Tensile Steel Wire net processing technology difficulty effectively and embrace the too thick shortcoming of button, make it work simplification and be easy to production, structure economics practicality; Next is to have further contemplated the structural issue that is easy to change after original anticorrosion glass liner wears out, and helps the raising of overall structure life cycle, and it is big to make full use of steel cable intensity once more.Superior fatigue resistance prolongs gas cylinder working life, therefore extremely has the use value of applying.

Right below in conjunction with drawings and Examples, be further described with regard to the utility model.

Fig. 1 is a multi-layer combined gas cylinder structural drawing of the present utility model.

As shown in the figure, this gas cylinder still is made up of valve protection cap 22, cylinder valve 21, bottle 8, glass liner 9, neck ring 5,12.Bottle 8 internal layer two ends fill with blend fiber by location, steel termination 6 and middle room and and steel termination 6 composite curings forms separation layer 15 and the outer surface layer 13 that inner shell 7,6 suits adopt separation layer 15 to disconnect through the termination again two-layer arc

tooth anchor ear

17,18,19

twine

14,16 of vertical line layer wire rope 16 and perpendicular horizontal line layer wire rope 14 and two-layer wire rope respectively and constitutes by the mixed fibre composite curing.Mixed fibre is made up of carbon fiber, nylon fiber, glass fibre, and forms inner casing packed layer 11, separation layer 15 and the outer surface layer 13 of bottle 8 with the epoxy resin composite curing.The vertical line layer wire rope 16 of bottle and perpendicular horizontal line layer wire rope 14 are closely to arrange to twine by the staggered in turn prestressing force of the

teeth groove

24,25,26 of arc

tooth anchor ear

17,18,19 to form.The sticking canvas layer 10 that is associated with one deck isolation glass liner 9 of bottle 8 inner layer surfaces that constituted.Glass liner 9 adopts the antiseptic rubber that tension force is arranged to make and is adhered to steel termination 6 by valve 3 place's packing rings 2.Cylinder valve 21 is connected on neck ring 5 internal threads by the suction port outside thread, and neck ring 5 connects by

sunk screw

20,23 and steel termination and pressure-bearing packing ring 2 and cylinder valve 21 suction port end faces docks with valve 3 end faces, mutual self-locking structure between the formation each several part.Valve 3 radially rosette 4 hot pressing by circumferential location are in channel rubber and form overall structures with glass liner 9, and radially rosette 4 diameters of valve 3 are less than the center-hole diameter of neck ring 5.Neck ring 5 is furnished with bonnet 22 by draw-in groove; The bottom of bottle 8 is silently neck rings 12 the same with top perforate neck ring 5.

Multi-layer combined gas cylinder is through sample test, and working pressure can reach 38MPa, and its weight ratio steel is light by 30%.
