Abstract
The utility model discloses a single-layer plate type cylinder gasket for diesels, which comprises a cylinder gasket body. A cylinder port, a water-oil hole and a bolt hole are arranged on the cylinder gasket body. The single-layer plate type cylinder gasket for the diesels is characterized in that the cylinder gasket body is made of a single-layer iron plate, a cylinder port seal rib is arranged on the periphery of the cylinder port by stamping, and a seal rubber ring is arranged on the cylinder gasket body positioned at the water-oil hole. The single-layer plate type cylinder gasket for the diesels has the advantages that since the cylinder gasket body is made of the single-layer iron plate, design defects of a multi-layer metal cylinder gasket are avoided, and manufacturing cost is reduced. Conventional seal ribs, seal cooling water and lubricating oil are substituted by the seal rubber ring, fine seal effect is achieved, and thereby faults of water leakage and oil leakage can be avoided.
Description
Technical field
The utility model relates to a kind of cylinder pad, particularly a kind of diesel engine single layer board head gasket.
Background technique
Along with the continuous development of engine technology, all to save material, to reduce cost, energy-conserving and environment-protective are target for motor and all kinds of accessory.Head gasket is bigger to performance impact on a motor component, be to be made at first by asbestos material, but along with the appearance of national relevant laws and regulations and the lifting of engine performance, asbestos washer begins to satisfy the usage requirement of motor gradually, the substitute is metal cylinder mat.The most spring stainless steel materials that use of present diesel engine metal cylinder mat, and adopt the sandwich plate structure.The upper and lower layer corrosion resistant plate thickness difference of head gasket relies on the top plate flange to produce height difference sealing cylinder oral area position, water oilhole place means of press seals muscle.Its subject matter is: 1, the top plate hardness of flange is lower, thereby causes the sealing force of sealed muscle lower, and faults such as leakage of oil occur leaking through regular meeting in the using process; 2, adopt stainless steel material, manufacture cost is higher.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of good sealing effect, can avoid occurring the oil leakage fault that leaks, the diesel engine single layer board head gasket of low cost of manufacture.
The diesel engine single layer board head gasket that the utility model relates to, comprise the head gasket body, on the head gasket body, be provided with cylinder port, water oilhole and bolt hole, its special way is: described head gasket body is made for individual layer iron plate, punching press has the seal with annular groove muscle around cylinder port, is positioned at water oilhole place and is provided with packer ring on the head gasket body.
Above-mentioned diesel engine single layer board head gasket, described packer ring are that the fluorine rubber on metal frame constitutes by a metal frame and sulfuration, and packer ring is by metal frame and the welding of head gasket body.
The utility model has the advantages that: because the head gasket body is made for individual layer iron plate, avoided the design deficiency of multiple layer metal head gasket, reduced manufacture cost; And substitute conventional seals muscle sealing cooling water and lubricant oil by packer ring, good sealing effect can avoid occurring the oil leakage fault that leaks.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A broken section enlarged view of Fig. 1;
Fig. 3 is the B-B broken section enlarged view of Fig. 1.
Among the figure: head gasket body 1, cylinder port 101, bolt hole 102, water oilhole 103, seal with annular groove muscle 104, packer ring 2, metal frame 201, fluorine rubber 202.
Embodiment
As shown in Figure 1, the utility model has a head gasket body 1, and described head gasket body 1 is made for individual layer iron plate, is provided with a plurality of cylinder port 101, bolt hole 102 and water oilhole 103 on head gasket body 1, around cylinder port 101, pass through stamping process processing cylinder mouth sealed muscle 104, referring to Fig. 2.On head gasket body 1, be positioned at water oilhole 103 places and be provided with packer ring 2, packer ring is that the fluorine rubber 202 on metal frame 201 constitutes by a metal frame 201 and sulfuration, packer ring 2 is by metal frame 201 and 1 welding of head gasket body, referring to Fig. 3.
Adopt said structure, avoided the design deficiency of stacked conducting plate head gasket, replace sealed muscle to make the sealing of cooling liquid and lubricant oil more reliable with packer ring; The seal with annular groove muscle is through verification experimental verification, and sealing effect is reliable; And, greatly reduce manufacture cost because the head gasket body only is made by individual layer iron plate.
Claims (2)
1. diesel engine single layer board head gasket, comprise the head gasket body, on the head gasket body, be provided with cylinder port, water oilhole and bolt hole, it is characterized in that: described head gasket body is made for individual layer iron plate, punching press has the seal with annular groove muscle around cylinder port, is positioned at water oilhole place and is provided with packer ring on the head gasket body.
2. diesel engine single layer board head gasket according to claim 1 is characterized in that: described packer ring is that the fluorine rubber on metal frame constitutes by a metal frame and sulfuration, and packer ring is by metal frame and the welding of head gasket body.
