Description

Filter mechanism and filter valve Technical Field The utility model relates to the technical field of magnetic filtration, in particular to a filtering mechanism and a filtering valve. Background When the liquid conveyed by the pipeline is used, the liquid is filtered while the on-off of the liquid is controlled by the filter valve, so that the liquid outlet quality at the tail end of the pipeline is ensured. The filter valve has a filter mechanism that typically includes a screen and a bottom cover to filter larger particles in the liquid, and the screen of the filter mechanism may become clogged during use, thus requiring periodic cleaning of the screen. In order to conveniently clean the filter screen, the filter screen and the bottom cover are usually fixed mutually and are arranged in the valve body of the filter valve, and when the filter screen needs to be cleaned, the filter screen can be taken down together only by taking down the bottom cover of the filter mechanism. In the prior art, because the materials of the filter screen and the bottom cover are different, the filter screen and the bottom cover are fixed in an interference fit or glue adhesion mode, the reliability of the fixing mode is not high, and the situation that the filter screen and the bottom cover are separated from each other easily after long-term use is realized.
