The technological scheme that the utility model adopts for its technical problem of solution is:
Head gasket, comprises cylinder port, water hole, oil duct junction, push-rod hole, positioning hole, bolt hole and sheetmetal; The periphery of head gasket is surrounded by sheetmetal, is filled with asbestos in head gasket, and head gasket is provided with cylinder port, and cylinder port is provided with three, and the side of head gasket is provided with water hole, oil duct junction, push-rod hole, positioning hole and bolt hole; Water hole is positioned at the side of cylinder port, and water hole is provided with three, lays respectively at the same side of three cylinder port, and middle cylinder port both sides are provided with oil duct junction, and oil duct junction to lay respectively between three water holes and is interspersed; The side of middle cylinder port is provided with pair of push rods hole, and push-rod hole and water hole are positioned at the same side relative to cylinder port; The cylinder port side of head gasket both sides is provided with positioning hole, and positioning hole is provided with three and water hole is positioned at the same side relative to cylinder port; The both sides of head gasket are provided with bolt hole, and bolt hole and water hole are positioned at the same side of cylinder port, and bolt hole and water hole are positioned on same level line;
In one embodiment, in asbestos, be provided with copper scale, to strengthen the thermal conductivity of head gasket, the temperature of balance cylinder block and cylinder cap;
In one embodiment, around water hole and oil duct junction, carry out the reinforcing of sheetmetal crimping, improve the intensity of head gasket and heat-transfer capability and ablation resistance;
Concrete, the periphery edge of cylinder port is to have the oxidation resistant nickel limit of high temperature resistance;
The utility model has the advantage of:
1. in head gasket, be filled with the asbestos of band copper scale, to strengthen the thermal conductivity of head gasket, the temperature of balance cylinder block and cylinder cap, head gasket is made to have higher heat resistance and certain elasticity, sealing is strengthened, and can repeated multiple timesly use, and decreases the number of times changing head gasket, what equipment was run is more lasting, and improves working efficiency.
2. be surrounded by sheetmetal outside head gasket, carry out the reinforcing of sheetmetal crimping around water hole and oil duct junction, make head gasket obtain higher intensity, ablation resistance and heat-transfer capability.
3. the periphery of cylinder port is inlayed to have high temperature resistance and is avoided the nickel limit of oxidation, can improve the burn-out-proof ability at cylinder port place, improve the working life of head gasket.
Accompanying drawing explanation
Fig. 1 is the structural representation of the head gasket that the utility model proposes.
