Description

Technical Field

[0001] This application relates to the technical field of pipe joints, and particularly to a joint for preventing filter screens from being blocked. Background Art

[0002] In daily life, pipelines are usually used to transport liquid media. Intricate pipelines need to be connected by pipe joints. There may be many impurities in the media transported by the pipelines. In order to ensure the cleanliness inside the pipelines, a filtering device needs to be installed in the pipe joints. Generally, the commonly used filtering device is a filter screen.

[0003] After the existing filtering device has been used for a long time, the filter screen inside the pipe joint is easily blocked by impurities, thus affecting the transportation efficiency of the pipeline. Generally, at this time, it is necessary to first remove the joint from the pipeline system, and then remove the filter screen to clean it, which is very troublesome. Therefore, improvements are now made to the joint for preventing filter screens from being blocked. Utility Model Content
