Technical Field
The invention is used in the field of compressors, and particularly relates to a cylinder head assembly, a compressor and refrigeration equipment.
Background
The cylinder head part of the traditional compressor is square, and the parts mainly comprise: the cylinder cover comprises a cylinder cover, a cylinder cover gasket, an air suction silencer, a valve plate component, an air suction valve plate, a valve plate gasket, cylinder cover screws and the like, wherein the number of the cylinder cover screws is four. The cylinder cover, the cylinder cover gasket, the valve plate component, the air suction valve plate and the valve plate gasket are in square design in appearance, and cylinder cover screw mounting holes are formed in four corner positions. The square cylinder head part has sufficient space, the mounting position of the exhaust valve plate can be freely arranged, the compression surface of the exhaust valve plate is far away from the sealing surface of the cylinder cover, and meanwhile, the exhaust valve plate is ensured to have enough effective working length.
In order to better save the material consumption of the compressor, the design of the compressor is more compact, the design cost of the product is reduced, the latest design scheme adopts the design of a circular cylinder head, and the material quota of cylinder head parts is greatly reduced. However, the circular cylinder head proposal brings new technical problems, namely, the installation space of the exhaust valve plate is insufficient because the design of the cylinder head part is too compact. In order to meet the requirement that the effective working length of the exhaust valve plate meets the requirement, the distance from the root part of the exhaust valve plate to the sealing and pressing surface of the cylinder cover is extremely small. If the traditional cylinder head gasket material is continuously adopted, because the deformation amount of the traditional cylinder head gasket material after compression is small, the whole exhaust valve plate has to be adopted, namely the exhaust valve plate has the appearance with the size corresponding to the whole sealing and pressing surface of the cylinder head, the appearance size is completely matched with the cylinder head gasket, the material consumption is large, and the cost of the exhaust valve plate is high. If in order to reduce the material quota of the exhaust valve plate and reduce the cost, the tongue-type exhaust valve plate is adopted and is matched with the traditional cylinder cover gasket material for use, the root part of the exhaust valve plate is too close to the sealing and pressing surface of the cylinder cover, and meanwhile, the deformation of the traditional cylinder cover gasket material after compression is very small, so that the pressing surface of the cylinder cover corresponding to the root part of the exhaust valve plate can be jacked up by the root part of the exhaust valve plate, the pressing force of the sealing and pressing surface of the cylinder cover close to the root part of the exhaust valve plate is insufficient, the leakage in the compressor is caused, the product performance is seriously influenced, and the cylinder cover gasket can be.
