Abstract
The utility model relates to a cylinder bed mattress, which is composed of a mattress on which a cylinder mouth hole, a water hole, an oil hole and a silk hole are arranged. The mattress is made of the composite materials of asbestos and iron sheets. The utility model is characterized in that a circle of convex sealing ring is arranged on the inner circumstance of the cylinder mouth hole, and a circle of annular lining is arranged in the sealing ring. The utility model ensures the sealing performance of a gas cylinder. Under the condition of the same pressure, the sealing performance is greatly improved and the dynamic energy of the gas cylinder is efficiently improved. The utility model also has the advantages of simple structure, long service life, convenient processing, low cost, etc.
Description
(1) technical field: the utility model relates to the cylinder accessory of motor, is a kind of cylinder mattress of sealing usefulness of cylinder port specifically.
(2) background technique: the cylinder mattress is used for the sealing of cylinder head and cylinder cap, at present, generally adopts asbestos sheetmetal structure, that is, whole cylinder mattress is made with asbestos, the internal orifice of cylinder mattress stripper band bag.Its outstanding advantage is that price is low.But because factors such as materials, its working life is often shorter.
Be the using effect of raising cylinder mattress, a kind of improved steel bed pad, the internal orifice of cylinder mattress is still used the stripper band bag, and the cylinder mattress adopts sandwich structure, promptly adds iron sheet in asbestos.The using effect of this cylinder mattress obviously improves, but still not ideal enough.
The aluminium alloy cylinder pad is the cylinder mattress of popular in the market another New Type Material,, steady quality in light weight with it, can use repeatedly, and be subjected to people's welcome.But the cylinder mattress of this structure is a plane contact between pad and the top cylinder cap, and area of contact is big, in press-fiting process, need big pressure could guarantee sealability, pressure is little will to influence sealing effect, the phenomenon that causes gas leakage of cylinder mouth or hydrophthalmia to leak, and influence is normally used; And pressure usually can make cylinder along damage when big, causes scrapping of cylinder.
(3) summary of the invention: the purpose of this utility model be to provide a kind of sealability better, long service life, lower-cost cylinder mattress.
The purpose of this utility model realizes by following scheme: a kind of cylinder mattress, form by pad, pad is provided with cutout hole, hydrophthalmia, oilhole and silk eye, pad is that the composite material of asbestos and iron sheet is made, in cutout hole, be arranged with the seal ring of a circle projection, seal ring is closely buckled on the pad, is characterized in: be provided with a circle lining papers in the seal ring.
The utility model is after adopting above structure, owing in cutout hole, be arranged with the seal ring of projection, and be provided with in the seal ring one the circle lining papers (constituting by iron wire, copper wire, aluminium wire usually), when press-fiting, cylinder cap only contacts with seal ring, reduced the area of contact between the two effectively, thereby guaranteed the sealability of cylinder mattress, under same pressure condition, sealability increases substantially, and has improved the kinetic energy of cylinder effectively, has simple in structure, practical, long service life, advantage such as easy to process.Simultaneously, compare, have lower-cost advantage with the aluminium alloy cylinder pad.
(4) description of drawings: accompanying drawing is the utility model overall structure schematic representation.
In the accompanying drawing: 1 is pad, and 2 is cutout hole, and 3 is hydrophthalmia, and 4 is oilhole, and 5 is the silk eye, and 6 is seal ring, and 7 is lining papers.
(5) embodiment: model utility is further described below in conjunction with embodiment:
Embodiment 1: as shown in drawings, a kind of cylinder mattress, form by pad (1), pad is provided with cutout hole (2), hydrophthalmia (3), oilhole (4) and silk eye (5), pad can be made by the composite material of asbestos and iron sheet, in the cylinder mouth, be arranged with the seal ring (6) of a circle projection, seal ring can adopt iron sheet, wraps in the cutout hole and encloses, can be by the pressure effect, seal ring is closely buckled on the pad, in seal ring, Feng Youyi encloses grommet (7), and grommet can be made up of metal ring, metal ring can constitute for the metallic material of circle, also can constitute for square metallic material.
Metallic material of the present utility model can be a kind of in irony, aluminium matter, the copper material, and adopting thickness (or diameter) be 0.5-1 times of asbestos composite wood thickness.
Claims (7)
1, a kind of cylinder mattress is made up of pad, and pad is provided with cutout hole, hydrophthalmia, oilhole and silk eye, pad is that the composite material of asbestos and iron sheet is made, be arranged with the seal ring of a circle projection in cutout hole, seal ring is closely buckled on the pad, it is characterized in that: be provided with a circle lining papers in the seal ring.
2, a kind of cylinder mattress according to claim 1, it is characterized in that: lining papers is a metal ring.
