Cylinder head assemblies, compressors and refrigeration equipment

Abstract

The invention discloses a cylinder head assembly, a compressor and a refrigeration device. The cylinder head assembly comprises a cylinder seat and a cylinder head component, wherein the cylinder headcomponent comprises an air suction valve sheet, a valve plate, an air exhaust valve sheet, a cylinder cover gasket and a cylinder cover, a cylinder hole is formed in the cylinder seat, the cylinder cover is connected to the cylinder seat, a circular assembly space is formed at the position, between the cylinder cover and the cylinder seat, of the front end of the cylinder hole, the air suction valve sheet, the valve plate, the air exhaust valve sheet and the cylinder cover gasket are arranged in the assembly space, the cylinder cover gasket is formed by adopting a rubber material, the air exhaust valve sheet is in a tongue-sheet type, the cylinder cover is provided with an air exhaust valve sheet root pressing surface capable of pressing the root of the air exhaust valve sheet, the cylinder cover gasket is provided with an air exhaust avoidance hole and an air exhaust valve sheet root pressing region located between the air exhaust valve sheet root pressing surface and the root of theair exhaust valve sheet, the compressor comprises the cylinder head assembly, and the refrigeration device comprises the compressor. According to the cylinder head assembly, the compressor and the refrigeration device, the advantages of miniaturization and low cost of a circular cylinder head are achieved, and the defect of high cost of the air exhaust valve sheet is avoided.

Description

technical field [0001] The invention is used in the field of compressors, and in particular relates to a cylinder head assembly, a compressor and refrigeration equipment. Background technique [0002] The cylinder head parts of traditional compressors are square, and the parts mainly include: cylinder head, cylinder head gasket, suction muffler, valve plate parts, suction valve plate, valve plate gasket, cylinder head screws, etc., among which the cylinder head The number of screws is four. The cylinder head, cylinder head gasket, valve plate parts, suction valve plate, and valve plate gasket have a square design, and cylinder head screw mounting holes are set at the four corners. The square cylinder head part has sufficient space, and the installation position of the exhaust valve plate can be freely set to keep the pressing surface of the exhaust valve plate away from the sealing surface of the cylinder head, and at the same time ensure that the exhaust valve plate has su...
