Problems solved by technology
[0002] In energy-saving irrigation, especially drip irrigation systems, the filter needs to be cleaned frequently to ensure the effect of drip irrigation. When the filter is maintained, the filter on the system pipeline needs to be removed and cleaned before continuing to irrigate. The disadvantage of filter mode is that it makes irrigation interruption or water supply unstable, etc.

The invention discloses a filter group in a non-intermittent water irrigation system. The filter group comprises a water supply pipeline and filters, wherein a water inlet of a reversing valve is connected with the water supply pipeline; a first water outlet and a second water outlet of the reversing valve are connected with an irrigation pipeline respectively; the same filters and the same valves are connected in series to pipelines between the first and second water outlets of the reversing valve and the irrigation pipeline respectively; a water outlet in the water supply pipeline and a water outlet in a cover of the reversing valve are communicated with a rotary switch respectively. The filter group in the non-intermittent water irrigation system has the remarkable advantage that the filters are maintained under the condition of non-intermittent water irrigation.
Description
Technical field: [0001] The invention relates to an irrigation technology, in particular to a filter group in an irrigation system for checking and repairing the filter under the condition of non-stop water supply. Background technique: [0002] In energy-saving irrigation, especially drip irrigation systems, the filter needs to be cleaned frequently to ensure the effect of drip irrigation. When the filter is maintained, the filter on the system pipeline needs to be removed and cleaned before continuing to irrigate. The disadvantage of the filter mode is that it can interrupt the irrigation or the water supply is unstable. Invention content: [0003] The purpose of the present invention is to provide a filter group in an irrigation system for checking and repairing filters without stopping water irrigation. [0004] The technical solution of the present invention is that the filter group in the non-stop water irrigation system includes a water supply pipeline and a filter...
