Air condition compressor discharge valve plate limiter

Abstract

The invention discloses an air condition compressor discharge valve plate limiter. The air condition compressor discharge valve plate limiter comprises a fixed part and a bending part, wherein one endof the fixed part is fixedly connected with one end of the bending part; the fixed part is of a surface plate structure; the bending part is of an arc-shaped plate-like structure; the upper surface of the other end of the bending part is provided with a lug; the upper surface of the lug is connected with an elastic buffer part; and the top of the elastic buffer part is connected with a carbon fiber ring component. The air condition compressor discharge valve plate limiter is practicable and has a reasonable structure, the stress condition can be greatly reduced under the condition of same contact area through the design of the carbon fiber ring component and the elastic buffer part structure, the contact area can be reduced effectively under the condition of same stress condition, the performance is greatly promoted, and the performance is greatly increased by compared with former products.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to an air conditioner compressor exhaust valve stopper. Background technique [0002] At present, the suction and discharge valves of refrigeration compressors are one of the key components in the compressor, which play a role in controlling the delivery of refrigerant in the refrigeration system. The working process is a process subject to alternating loads. The existing suction When the valve plate is working, its opening process is like a cantilever beam swinging up and down. There is an inclination angle when the reed and the valve plate collide with each other. However, the existing compressor exhaust valve plates are all made of high carbon steel or stainless steel. The interaction with the compressor valve seat made of metal material has become an inevitable main noise, and the noise generated by the compressor mainly comes from the running sound of the compre...

[0002] At present, the suction and discharge valves of refrigeration compressors are one of the key components in the compressor, which play a role in controlling the delivery of refrigerant in the refrigeration system. The working process is a process subject to alternating loads. The existing suction When the valve plate is working, its opening process is like a cantilever beam swinging up and down. There is an inclination angle when the reed and the valve plate collide with each other. However, the existing compressor exhaust valve plates are all made of high carbon steel or stainless steel. The interaction with the compressor valve seat made of metal material has become an inevitable main noise, and the noise generated by the compressor mainly comes from the running sound of the compressor motor, the collision between the suction and discharge valve plates of the compressor and the limit plate. Noise, etc. These sounds are unfavorable to people's living environment. For the noise generated by the exhaust valve plate and the limit plate, the noise generated under the same impact force will follow the valve plate reed and limit plate. The contact area of ​​the plate varies with the size of the impact contact area. The larger the impact contact area, the greater the noise generated when the exhaust valve plate collides with the limit plate. Now, in order to reduce the noise of the compressor, the metal valve plate has a large mass, and the compressor overcomes the valve plate. The gas resistance loss of its own quality causes a large pressure loss in the compressor, which makes the pressure coefficient low and the gas transmission coefficient low. Therefore, how to solve and reduce the noise generated by the collision between the existing limiter and the exhaust valve plate has become the solution of the application of the present invention. technical issues
