Method for reducing pipeline vibration stress, buffer, elbow structure and application

Abstract

The invention belongs to the technical field of air conditioners, and discloses a method for reducing pipeline vibration stress, a buffer, an elbow structure and application. By adding the buffer to the pipeline elbow, with a small testing margin, on an air conditioner external unit pipeline with design beyond improvement, the pipeline shutdown stress is reduced. The buffer comprises a shell, and the shell is a stainless steel material; the shell is filled with high-pressure gas; and a seal of the shell is a film material resistant to high temperatures and high pressure, and can expand under force action. According to the method for reducing the pipeline vibration stress, the buffer, the elbow structure and application, the buffer is mainly added to the air conditioner external unit pipeline, by adding the buffer to the pipeline elbow, with the small testing margin, on the external unit pipeline with the design beyond improvement, the pipeline shutdown stress is reduced when an air conditioner is turned off, and the problem of high-load shutdown pipe-breaking and trouble of a user are avoided, so that user experience is improved; and when the air conditioner works in high-load working conditions, stress-strain can be effectively reduced, and 95% stress absorption can be reached.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a method for alleviating the vibration stress of pipelines, a buffer, an elbow structure and applications. Background technique [0002] At present, with the development of the economy, people's living standards have been improved, and the demand for air conditioners is also increasing. The usage habits of air conditioners in different regions are different, and the environmental load is different. The user has brought a lot of trouble. The broken pipe is mainly due to the large operating load of the air conditioner and the large vibration of the pipeline. Warranty, to bring troubles to users. Therefore, there is an urgent need for a method for alleviating the shutdown stress of pipelines, avoiding the problem of broken pipes, and improving user experience. [0003] Through the above analysis, the existing problems and defects of the prior art are as follow...
