It is installed on the pipeline to remove larger solid impurities in the fluid, so that machinery and equipment (including compressors, pumps, etc.) and instruments can work and operate normally, achieve a stable process, and ensure safe production. It plays a more important role in practice.

[0003] However, the following problems still exist in actual use:

Therefore, after it is damaged or used for a long time, it cannot be replaced, which will reduce the actual filtering effect and is not conducive to its promotion and use in practice.

[0005] (2) The existing pipeline valve filter has problems during use. The filter is installed on the pipeline valve by bolts, so the fixing method is relatively simple and cannot be stably installed in different positions according to actual conditions, which will reduce the stability in actual use.

[0006] For this reason, the utility model launches a filter with a cleaning function for a pipeline valve. Utility Model Content

At the same time, timely replacement can improve the actual filtering effect, which is conducive to the promotion and use in practice.

[0016] 2. The filter with a cleaning function for the pipeline valve can be used with a stabilizing mechanism. When the filter with a cleaning function for the pipeline valve is used, when the whole is installed, first, the sliding plate can be slid on the inner wall of the rectangular groove by opening a rectangular groove on the outer surface of the filter tube. After the sliding plate is slid to the corresponding installation position according to the actual situation, the T-shaped sliding block can be slid on the inner wall of the sliding plate, or the T-shaped sliding block can be slid on the inner wall of the sliding plate to the relevant installation position. After the movement is completed, the external pipeline can be connected to the inside of the filter tube.
