Description

Air conditioner compressor exhaust valve plate stopper

Technical Field

The invention relates to the technical field of refrigeration equipment, in particular to a limiter for an air discharge valve plate of an air conditioner compressor.

Background

The suction and discharge valve plate of the present refrigeration compressor is one of the key parts in the compressor, which plays the role of controlling the delivery of the refrigerant in the refrigeration system, the working process is a process under the action of alternating load, when the existing suction valve plate works, the opening process is the same as the up-and-down swing of a cantilever beam, an inclined angle exists when the reed collides with the valve plate, the existing compressor discharge valve plate is made of high carbon steel or stainless steel, the interaction between the existing suction valve plate and the compressor valve seat made of metal material forms inevitable main noise, the noise generated by the compressor mainly comes from the running sound of the compressor motor, the noise generated by the collision between the compressor suction and discharge valve plate and the limiting plate, and the like, the noise is unfavorable noise to the living environment of people, for the noise generated by the discharge valve plate and the limiting plate, the noise generated under the same impact force is different along with the contact area of the valve plate reed and the limiting plate, the larger the impact contact area is, the larger the noise generated when the exhaust valve plate collides with the limiting plate is, but now in order to reduce the noise of the compressor, the mass of the metal valve plate is large, the compressor overcomes the gas resistance loss of the mass of the valve plate, so that the pressure loss of the compressor is large, the pressure coefficient is low, and the gas transmission coefficient is low, so that the technical problem to be solved by the invention is how to solve and reduce the noise generated by the impact of the existing limiting device and the exhaust valve plate.

Disclosure of Invention

Therefore, the air conditioner compressor exhaust valve plate limiter provided by the invention is practical in product and reasonable in structure, and can effectively solve the problems in the background technology.

The invention is realized by the following means:

Preferably, the carbon fiber annular member comprises a carbon fiber annular ring, the carbon fiber annular ring is connected with a carbon fiber conical column through a plurality of groups of carbon fiber connecting pieces relative to the inner ring, and the central line of the carbon fiber conical column is parallel to the central line of the carbon fiber annular ring.

Preferably, the one end of fixed part is kept away from to the flexion is oval structure, oval face upper end is located to the lug, the upper surface of lug is equipped with the depressed center.

The carbon fiber conical column has a reasonable structure, the contact area can be greatly reduced through the special structure of the carbon fiber annular component, when the central line of the carbon fiber conical column and the central line of the carbon fiber annular ring are in the same straight line, the carbon fiber annular material can be uniformly stressed and acts on the elastic buffer part, the impact speed can be reduced, the corresponding stress is reduced, and the buffer effect can be effectively improved due to the structural characteristics of the carbon fiber annular component, so that the further noise reduction is realized; when the central line of the carbon fiber conical column is parallel to the central line of the carbon fiber annular ring, the elastic buffer part is stressed in the direction deviating from the vertical direction due to the stress of the carbon fiber conical body, so that the elastic buffer part rebounds the carbon fiber annular member, the contact area of the carbon fiber conical column is gradually increased, and the reduction of the contact area also ensures the noise reduction effect; compared with the noise reduction product applied by the company, the noise reduction of the product applied by the invention can be improved by 30-40%.

The invention has the beneficial effects that: the carbon fiber annular component has the advantages that the carbon fiber annular component is practical, the structure is reasonable, the stress condition is greatly reduced under the condition of the same contact area through the design of the carbon fiber annular component and the elastic buffer part structure, the contact area can be effectively reduced under the condition of the same stress condition, the performance is greatly improved, and the performance is greatly improved compared with the performance of the prior product.
