技术领域 technical field
本实用新型涉及发动机零部件，具体涉及一种发动机单缸密封的气缸垫。 The utility model relates to engine components, in particular to a single-cylinder sealed cylinder pad of the engine.
背景技术 Background technique
发动机气缸垫用于密封发动机燃烧室，在发动机工作状态下，气缸达到最大燃气压力时，能够确保燃气不发生泄露现象，要求气缸垫有一定的强度和弹性，以便保证发动机工作时燃烧室保证密封。通常发动机所采用的气缸垫，按缸数区分有单缸气缸垫和多缸整体式气缸垫；按材料分有钢质气缸垫、铝质气缸垫、铜质气缸垫等。钢质材料的气缸垫强度好，但弹性差，密封性较差；铜质和铝质气缸垫因压缩变形大，回弹性能好，在中小功率、低爆压的发动机中应用较广，但在大功率、高爆压发动机上，因材质强度较差，在气缸达到最大燃气压力时变形大，密封性差。CN 203547970 U公开的“一种气缸垫结构”，包括有三层基片组成的垫片本体结构，其中间层为镀铝板，上下两层均为不锈铁层，垫片本体上分布有间隔排列的气缸孔，气缸孔外侧的垫片本体上分布有安装孔、水孔、螺丝孔以及其一侧的挺杆孔，垫片本体的一端设有梯形定位孔，气缸孔、螺纹孔、挺杆孔以及梯形定位孔的外边缘位置分别设有橡胶密封凸筋。其性能比较好，使用寿命长，同时拆装后可回收利用，利于环保，通过垫片本体上气缸孔、螺纹孔、挺杆孔以及梯形定位孔的外边缘位置的橡胶密封凸筋的结构，其密封性能好，满足了内燃机对热负荷和机械负荷的要求，而且通过纵向定位凹槽和端部梯形定位孔的结构，使其使用过程中，稳定性好。随着发动机技术水平发展，发动机爆发压力越来越高，缸内燃烧的高温高压燃气的密封问题日益严峻。因此解决大功率、高爆压发动机气缸密封的问题迫在眉睫。 The engine cylinder gasket is used to seal the engine combustion chamber. When the engine is working, when the cylinder reaches the maximum gas pressure, it can ensure that the gas does not leak. The cylinder gasket is required to have a certain strength and elasticity to ensure that the combustion chamber is sealed when the engine is working. . Generally, the cylinder head gasket used in the engine can be divided into single-cylinder cylinder head gasket and multi-cylinder integral cylinder head gasket according to the number of cylinders; according to the material, there are steel cylinder head gasket, aluminum cylinder head gasket, copper cylinder head gasket, etc. Steel cylinder gaskets have good strength, but poor elasticity and poor sealing; copper and aluminum cylinder gaskets are widely used in engines with small and medium power and low explosion pressure due to large compression deformation and good resilience performance. In high-power, high-explosion-pressure engines, due to poor material strength, when the cylinder reaches the maximum gas pressure, the deformation is large and the sealing is poor. CN 203547970 U discloses "a cylinder head gasket structure", which includes a gasket body structure composed of three layers of substrates. The middle layer is an aluminum plate, and the upper and lower layers are stainless iron layers. There are mounting holes, water holes, screw holes and tappet holes on one side of the gasket body outside the cylinder hole. One end of the gasket body is provided with a trapezoidal positioning hole. The cylinder hole, threaded hole, tappet The outer edges of the hole and the trapezoidal positioning hole are respectively provided with rubber sealing ribs. Its performance is relatively good, its service life is long, and it can be recycled after disassembly and assembly, which is beneficial to environmental protection. Through the structure of the rubber sealing ribs on the cylinder hole, threaded hole, tappet hole and the outer edge of the trapezoidal positioning hole on the gasket body, Its sealing performance is good, which meets the requirements of the internal combustion engine for thermal load and mechanical load, and through the structure of the longitudinal positioning groove and the trapezoidal positioning hole at the end, it has good stability during use. With the development of engine technology, the explosion pressure of the engine is getting higher and higher, and the sealing problem of the high-temperature and high-pressure gas burned in the cylinder is becoming more and more serious. Therefore, it is extremely urgent to solve the problem of cylinder sealing of high-power, high-explosion-pressure engines.
发明内容 Contents of the invention
本实用新型的目的是提供一种发动机单缸密封的气缸垫，其具有可靠的密封性能，能够满足大功率、高爆压发动机气缸密封的要求。 The purpose of the utility model is to provide a cylinder head gasket for single-cylinder sealing of an engine, which has reliable sealing performance and can meet the requirements for sealing the cylinder of a high-power, high-explosive-pressure engine.
本实用新型所述的一种发动机单缸密封的气缸垫，包括呈环形的气缸垫本体，其特征是：所述气缸垫本体为钢质，表面附着有金属的镀层。 The utility model relates to a sealed cylinder head gasket for a single cylinder of an engine, which includes a ring-shaped cylinder head gasket body, and is characterized in that: the cylinder head gasket body is made of steel, and a metal coating is attached to the surface.
所述的一种发动机单缸密封的气缸垫，其所述气缸垫本体的材质为Q235冷轧板。采用Q235冷轧板制作气缸垫本体，强度好，能够承受高爆压的冲击。 The cylinder head gasket for single-cylinder sealing of an engine is described, and the material of the cylinder head gasket body is Q235 cold-rolled plate. The cylinder gasket body is made of Q235 cold-rolled sheet, which has good strength and can withstand the impact of high explosion pressure.
所述的一种发动机单缸密封的气缸垫，其所述气缸垫本体表面的镀层为纯铜，镀层厚度为0.1mm-0.2mm。 The cylinder head gasket for the single-cylinder seal of the engine, the plating layer on the surface of the cylinder head gasket body is pure copper, and the thickness of the plating layer is 0.1mm-0.2mm.
本实用新型结构简单，安装方便，生产成本低，有着极好的经济效益；采用一缸一盖的方式安装，安装和拆卸都非常简便。由于气缸垫本体采用Q235冷轧板，强度好，能够承受高爆压的冲击，同时在气缸垫本体表面上镀一层纯铜，使气缸垫表面产生较大的弹性变形，让气缸垫和气缸以及气缸盖表面贴合的更加紧密，使气缸垫的密封性更好，采用本结构的气缸垫，能解决大功率、高爆压发动机上气缸垫密封性差的问题。 The utility model has the advantages of simple structure, convenient installation, low production cost and excellent economic benefits; it is installed in the way of one cylinder and one cover, and the installation and disassembly are very convenient. Because the body of the cylinder head gasket is made of Q235 cold-rolled plate, it has good strength and can withstand the impact of high explosion pressure. And the surface of the cylinder head is more tightly bonded, so that the sealing performance of the cylinder head gasket is better. The cylinder head gasket with this structure can solve the problem of poor sealing performance of the cylinder head gasket on a high-power, high-explosive-pressure engine.
