Abstract
The utility model provides a take interbedded cylinder gasket of graphite alkene, includes the cylinder gasket pad body and fills up the body and go up each function hole that sets up, fill up the body for multilayer composite construction, including lieing in two copper -aluminium alloy pieces on the upper and lower surface course, accompany in the middle of the copper -aluminium alloy piece one through the galvanized corrosion resistant plate of spurt as the core, and between corrosion resistant plate and upper and lower layer of copper -aluminium alloy piece respectively the shaping have one deck graphite alkene layer. The utility model discloses it is high temperature resistant, corrosion -resistant, can guarantee effectively that the hydro -cylinder moves the leakproofness of in -process.
Description
Technical field
The utility model relates to internal-combustion engine cylinder gasket technical field, is specially a kind of cylinder gasket possessing the band graphene interlayers of better shock-resistant resistance to high temperature.
Background technique
In internal-combustion engine, head gasket to be interposed on the junction plane between cylinder block and head and fastened, to ensure the sealing of firing chamber.
In general, head gasket, except possessing preferably except sealability, also requires there are enough mechanical strengths under high temperature, high-pressure gas effect, not fragile; Also should possess certain heat-resisting and decay resistance, not burning, not septic yeast under the effect of pressure machine oil and cooling water simultaneously.Traditional head gasket is composited by clamping asbestos slate in the middle of two panels metallic shim or two-layer asbestos slate therebetween layer of metal spurt plate, and this pad is very easy to damage, and working life is short, and assembling and dissembling process easily produces environmental pollution, is unfavorable for environmental protection.Also the fluorine rubber after having some to use sulfuration carries out sealing to increase the adhesion of stainless steel substrate, but this structure can in internal-combustion engine continuous operation, in all ever-increasing situation of heat load and mechanical load, its edge can produce sclerosis and produce certain distortion, once this deforms more than scope, affects the sealing of head gasket between cylinder head and cylinder body.
Model utility content
The technical problem that the utility model solves is to provide a kind of cylinder gasket with graphene interlayers, to solve the shortcoming in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of cylinder gasket with graphene interlayers, comprise each functional hole that head gasket pad and pad are arranged, wherein, described pad is multi-layer compound structure, comprise the two panels albronze sheet be positioned on upper and lower surface layer, accompany one piece through zinc-plated corrosion resistant plate of making a spurt as central layer in the middle of albronze sheet, and form one deck graphene layer respectively between corrosion resistant plate and upper and lower layer albronze sheet.
In the utility model, described functional hole includes but not limited to cylinder-bore, water hole, tappet bore and oilhole, its edge by impact style be processed with for realize seal burr, burr position by through vulcanizing treatment fluorine rubber edge sealing or inside hole, be provided with the resistance to scraper ring of silicone rubber.
In the utility model, described graphene layer stretches out pad and respectively to the bound edge that turns up outside upper and lower two-layer albronze sheet in pad outer rim, and in bound edge position by the fluorine rubber edge sealing through vulcanizing treatment.
Beneficial effect: the utility model structure is simple, easy to process, widely applicable, high temperature resistant, corrosion-resistant, and internal-combustion engine can be made to be issued to good sealing effect at high temperature, high pressure, there is easy for installation, the advantage such as good sealing effect and long service life simultaneously, and at marginal position, there is good stickability, the surface of substrate can be closely adhered to, difficult drop-off, improves the reliability of head gasket.
