Abstract
The invention relates to an all-metal cylinder gasket, belonging to the technical field of cylinder gasket structure. The all-meal cylinder gasket having multiple sealings comprises an inner layer 2, an upper layer 3, and a lower layer 4 of the gasket matched with the sealing structure of the cylinder end, and is characterized in that at least two annular row sealing waveforms 1 of the inner layer 2 are arranged at the periphery of the cylinder end of the cylinder gasket, the gas sealing part is equivalent to be arranged with multiple sealing defence lines, when the burst gas of the cylinder breaks through the first defence line, the later defence lines can stop the gas, thereby greatly improving the sealing effect of the cylinder end and reducing the generation of leakage and cylinder slugging. The invention has ingenious conception, reasonable design, good sealing performance, high intensity, and reliable use, has two or more sealing waveforms, can effectively reduce the generation of leakage and cylinder slugging, and has obvious economic benefit.
Description
One, technical field
The present invention relates to a kind of full-metallic cylinder gasket, belong to technical field of cylinder gasket structure.
Two, background technique
As everyone knows, cylinder gasket is to be used for connecting cylinder head and cylinder block, simultaneously lubricant oil, cooling liquid and the cylindrical implosion body of getting angry is sealed, the good and bad sealing that directly influences cylinder of cylinder gasket, and the gas seal of existing metal cylinder mat sheet is to adopt to seal waveform together in the compacting of cylinder oral area position and come sealing gas, it is unreal to adopt this structure to produce cylinder seal sometimes, leaks gas.
Three, summary of the invention
The objective of the invention is to solve the deficiency that above-mentioned prior art exists, provide a kind of and be skillfully constructed, reasonable in design, good airproof performance with multiple-sealed full-metallic cylinder gasket.
Of the present invention a kind of with multiple-sealed full-metallic cylinder gasket, comprise the pad internal layer 2, upper strata 3, the lower floor 4 that match with cylinder seal with annular groove structure, special way is to be at least twice in the cylinder oral area position of cylinder gasket along the ring-like sealing waveform 1 of the peripheral internal layer 2 that is provided with of cylinder mouth, so just be equivalent to set up multiple-sealed defence line at the gas seal position, cylinder outburst gas has broken through the first line of defence, also have second and third .... the defence line, road, thereby can well improve the sealing effect of cylinder oral area position, reduce generation towards the cylinder gas leak phenomenon.
The described internal layer 2 that is provided with in the cylinder oral area position of cylinder gasket two seals waveform 1 at least is to be formed by compacting, and sealing waveform 1 is positioned at the U type bending 5 on the peripheral pad of cylinder mouth upper strata 3;
The internal layer 2 that described cylinder oral area position at cylinder gasket is provided with at least the surface of contact of two seals waveform 1 and the U type bending 5 on upper strata 3 can guarantee that good sealing property is as the criterion;
Consider that from practical with economic angle above-mentioned sealing waveform in the compacting of the cylinder oral area position of cylinder gasket is twice or three roads.
The present invention is a kind of to be skillfully constructed with multiple-sealed full-metallic cylinder gasket, reasonable in design, be provided with twice to multiple tracks and seal waveform, have good airproof performance, the intensity height, use advantages such as reliable, reduced effectively, have tangible economic benefit towards the generation of cylinder gas leak phenomenon.

Fig. 2: prior art a kind of with multiple-sealed full-metallic cylinder gasket cylinder oral area position sectional view;
Fig. 3: of the present invention a kind of with multiple-sealed full-metallic cylinder gasket cylinder oral area position sectional view.
Five, embodiment
Following with reference to accompanying drawing, provide the specific embodiment of the present invention, be used for formation of the present invention is further specified.
Present embodiment a kind of with multiple-sealed full-metallic cylinder gasket with reference to figure 1-3, comprise the pad internal layer 2 that matches with cylinder seal with annular groove structure, upper strata 3, lower floor 4, the circular row sealing waveform 1 of the internal layer 2 that is provided with along cylinder mouth periphery in the cylinder oral area position of cylinder gasket is twice, so just be equivalent to set up multiple-sealed defence line at the gas seal position, cylinder outburst gas has broken through the first line of defence, also has defence line, second road, thereby can well improve the sealing effect of cylinder oral area position, minimizing is towards the generation of cylinder gas leak phenomenon, internal layer 2 two seals waveforms 1 are formed by compacting, sealing waveform 1 is positioned at the U type bending 5 on the peripheral pad of cylinder mouth upper strata 3, and the size of the surface of contact of the U type bending 5 on two seals waveform 1 and upper strata 3 is for can guarantee that good sealing property is as the criterion.
Present embodiment a kind of with multiple-sealed full-metallic cylinder gasket with reference to figure 1-3, comprise the pad internal layer 2, upper strata 3, the lower floor 4 that match with cylinder seal with annular groove structure, the ring packing waveform 1 of the internal layer 2 that is provided with along cylinder mouth periphery in the cylinder oral area position of cylinder gasket is three roads, so just be equivalent to set up multiple-sealed defence line at the gas seal position, cylinder outburst gas has broken through the first line of defence, also have second road and three lines of defence, thereby can well improve the sealing effect of cylinder oral area position, reduce generation towards the cylinder gas leak phenomenon.
The present invention is a kind of to be skillfully constructed with multiple-sealed all metal cylinder washer, reasonable in design, The twice that are provided with to multiple tracks seals waveform, has good airproof performance, and the intensity height uses the advantages such as reliable, Effectively reduce the generation of rushing the cylinder gas leak phenomenon, had obvious economic benefit.
Claims (4)
1, a kind of with multiple-sealed full-metallic cylinder gasket, comprise the pad internal layer (2), upper strata (3), the lower floor (4) that match with cylinder seal with annular groove structure, be characterised in that the ring packing waveform (1) of the internal layer (2) that is provided with along cylinder mouth periphery in the cylinder oral area position of cylinder gasket is at least twice.
