Description

Technical Field

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

[0002] Y-type filter is an indispensable filtering device in the pipeline system of conveying medium. Y-type filter is usually installed at the inlet end of pressure reducing valve, pressure relief valve, water level valve or other equipment to remove impurities in the medium to protect the normal use of valves and equipment. Y-type filter has played a great role in the treatment of domestic wastewater, sewage and industrial sewage; and has effectively treated a large amount of domestic and industrial sewage in the application of various industries, so that precious water resources have been effectively reused.

[0003] The backwash Y-type filter filters the impurity particles in the water through the filter. When there are too many impurity particles, other water will be pumped in through the water pump to wash away the impurities on the filter and discharge them out of the pipe. There is no need to manually clean the filter. However, since the flow direction of water in the valve is fixed, with the long-term use of the filter, more impurities will accumulate on one side of the water outlet of the filter, while less impurities will accumulate on the other side, making the filter very easy to clog, and the frequency of cleaning the filter will be increased. During cleaning, the pipe is closed, affecting the delivery of water flow. Utility Model Content
