Abstract
The utility model relates to the head gasket of a kind of motor single cylinder sealing, comprises ringwise head gasket body, it is characterized in that: described head gasket body is steel, and surface attachment has the coat of metal.The material of described head gasket body is Q235 cold-reduced sheet.The coat of metal of described head gasket body surface is fine copper, and thickness of coating is 0.1mm-0.2mm.The utility model has reliable sealability, can meet the requirement of high-power, high detonation pressure engine cylinder seal.
Description
Technical field
The utility model relates to engine component, is specifically related to the head gasket of a kind of motor single cylinder sealing.
Background technique
Engine cylinder ring is used for canned motor firing chamber, under engine behavior, when cylinder reaches maximum gaseous-pressure, can guarantee that combustion gas leakage phenomenon does not occur, require that cylinder is lined with certain intensity and elasticity, so that firing chamber ensures sealing when ensureing engine operation.The head gasket that usual motor adopts, distinguishes by cylinder number and has single cylinder head gasket and multi-cylinder integral formula head gasket; Divide by material and have steel head gasket, aluminium matter head gasket, copper head gasket etc.The head gasket intensity of steel material is good, but poor flexibility, sealing is poor; Copper and aluminium matter head gasket because of compressive strain large, resilience is good, applies wider in the motor of middle low power, low detonation pressure, but in high-power, high detonation pressure engine, because Material Strength is poor, when cylinder reaches maximum gaseous-pressure, distortion is large, and sealing is poor.CN 203547970 U disclosed " a kind of cylinder head gasket structure ", include the shim body structure of three layers of substrate composition, its mesosphere is alclad sheet, two-layerly up and down be stainless iron layer, shim body is distributed with spaced cylinder-bore, shim body outside cylinder-bore is distributed with the tappet bore of mounting hole, water hole, screw hole and its side, one end of shim body is provided with trapezoidal positioning hole, and the outward edge position of cylinder-bore, tapped hole, tappet bore and trapezoidal positioning hole is respectively equipped with rubber seal convex tendon.Its Performance Ratio is better, long service life, recoverable after dismounting simultaneously, be beneficial to environmental protection, by the structure of the rubber seal convex tendon of the outward edge position of shim body upper cylinder hole, tapped hole, tappet bore and trapezoidal positioning hole, its good seal performance, meet the requirement of internal-combustion engine to heat load and mechanical load, and pass through the structure of the trapezoidal positioning hole of longitudinal register groove and end, make in its using process, good stability.Along with engine technology levels, engine flare increasing pressure is high, and the sealing problem of the high-temperature high-pressure fuel gas of in-cylinder combustion is increasingly serious.Therefore the problem solving high-power, high detonation pressure engine cylinder seal is extremely urgent.
Summary of the invention
The purpose of this utility model is to provide the head gasket of a kind of motor single cylinder sealing, and it has reliable sealability, can meet the requirement of high-power, high detonation pressure engine cylinder seal.
The head gasket of a kind of motor single cylinder sealing described in the utility model, comprises ringwise head gasket body, it is characterized in that: described head gasket body is steel, and surface attachment has the coating of metal.
The head gasket of described a kind of motor single cylinder sealing, described in it, the material of head gasket body is Q235 cold-reduced sheet.Adopt Q235 cold-reduced sheet to make head gasket body, intensity is good, can bear the impact of high detonation pressure.
The head gasket of described a kind of motor single cylinder sealing, described in it, the coating of head gasket body surface is fine copper, and thickness of coating is 0.1mm-0.2mm.
The utility model structure is simple, and easy for installation, cost of production is low, has fabulous economic benefit; Adopt the mode that a cylinder one covers to install, mount and dismount all very easy.Because head gasket body adopts Q235 cold-reduced sheet, intensity is good, the impact of high detonation pressure can be born, on head gasket body surface, plate one deck fine copper simultaneously, make head gasket surface produce larger resiliently deformable, what allow head gasket and cylinder and cylinder head surface fit is more tight, makes the better tightness of head gasket, adopt the head gasket of this structure, the problem of high-power, high detonation pressure engine upper cylinder pad sealing difference can be solved.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model;
Fig. 2 is the B-B sectional view of Fig. 1;
Fig. 3 is the schematic diagram that the utility model installs on the engine.
Mark in figure, 1 is cylinder block, and 2 is cylinder liner, and 3 is head gasket body, and 4 is cylinder head, and 6 is coating.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
See the head gasket of a kind of motor single cylinder sealing shown in Fig. 1 and Fig. 2, comprise ringwise head gasket body 3, its outstanding substantive distinguishing features is: described head gasket body is steel, and surface attachment has the coating 6 of metal.
Preferred scheme is, the material of described head gasket body 3 is Q235 cold-reduced sheet.Adopt Q235 cold-reduced sheet to make head gasket body, intensity is good, can bear the impact of high detonation pressure.
The coating 6 of described head gasket body surface is fine copper, and the thickness of coating 6 is 0.2mm.To make head gasket surface produce larger resiliently deformable, what allow head gasket and cylinder and cylinder head surface fit is more tight, improves the sealing of head gasket.
If the thickness of coating 6 is 0.1mm, 0.15mm, namely form other embodiment.
See Fig. 3, the installation sealing explanation of the head gasket body with copper layer, cylinder block 1 is connected with cylinder liner 2, cylinder liner 2 is connected with head gasket body 3, head gasket body 3 is adjacent with cylinder head 4, by the screwing force of clamping bolt, the upper and lower surface of head gasket is closely connected with cylinder head surface and cylinder liner surface respectively, plays the effect of sealing gas in the jar.
Claims (2)
