Embodiment Construction

[0028] see in conjunction Figure 1 to Figure 7 As shown, according to the embodiment of the present application, the valve sheet includes a base layer valve sheet 1, a damping layer valve sheet 2 and a constrained layer valve sheet 3, and the damping layer valve sheet 2 is located between the base layer valve sheet 1 and the constraining layer valve sheet 3, and the base layer The valve plate 1, the damping layer valve plate 2 and the constrained layer valve plate 3 are fixedly connected.

[0029] In this embodiment, the valve plate adopts at least three-layer structure, wherein the role of the base valve plate 1 is to directly contact with the valve seat, and the rigidity is relatively high, so as to avoid the direct contact between the damping layer valve plate 2 and the valve seat, so as to avoid the damping layer valve plate 2 Damage occurs under high-frequency impact; the damping layer valve plate 2 acts as a damper and will dissipate part of the vibration energy of the ...

Abstract

The invention provides a valve plate, an exhaust valve assembly, a compressor and an air conditioner. The valve plate comprises a base layer valve plate (1), a damping layer valve plate (2) and a restraint layer valve plate (3), the damping layer valve plate (2) is located between the base layer valve plate (1) and the restraint layer valve plate (3), and the base layer valve plate (1), the damping layer valve plate (2) and the restraint layer valve plate (3) are fixedly connected. According to the valve plate, part of impact energy can be consumed, abrasion of the valve plate is effectively relieved, and the reliability of the compressor is improved.

Description

technical field [0001] The present application relates to the technical field of compressors, in particular to a valve plate, an exhaust valve assembly, a compressor and an air conditioner. Background technique [0002] Compressors are widely used in refrigeration, military and other industries. According to their working principles, they can be divided into volumetric and speed compressors. Compressors need to complete a series of processes such as suction, compression, and exhaust. Many compressors are exhausting An exhaust valve is always needed to control the exhaust pressure, such as: free piston compressor, rolling piston compressor, sliding vane machine, etc. The valve plate will be affected by the internal and external pressure difference during the switching process, which will have a certain impact on the valve seat, resulting in wear on the surface of the valve plate and valve seat, and poor reliability. Contents of the invention [0003] Therefore, the technic...
