Description

Technical Field

[0001] The utility model relates to the technical field of Y-type filters, in particular to a fully automatic backwashing Y-type filter. Background Technique

[0002] The Y-type filter is a commonly used pipeline filtering device. It mainly captures solid particles in the fluid through a filter screen or a filter basket to protect the normal operation of pipelines and equipment. The Y-type filter is installed at the inlet end of a pressure reducing valve, a pressure relief valve, a constant water level valve or other equipment to remove impurities in the medium, such as rust, sand grains, and a small amount of solid particles in the liquid, to protect the normal use of valves and equipment.

[0003] At present, the Y-type filter is a commonly used filtering device. Its working principle is to block impurities in the fluid through an internally inserted filter screen to protect the normal operation of subsequent equipment or pipelines. However, with the increase of the use time, a large amount of impurities will accumulate on the filter screen, resulting in a decrease in the filtering efficiency and even possibly affecting the normal operation of the entire system. Therefore, regular cleaning and replacement of the filter screen are the keys to ensuring the normal operation of the Y-type filter. Frequent disassembly and installation of the filter screen will consume a lot of time and manpower. Especially in large systems or production lines, such operations may cause production interruptions and reduce the overall work efficiency. In some special environments (such as high temperature, high pressure or corrosive environments), the operation of replacing the filter screen may be more complicated and dangerous. Summary of the Utility Model
