| Abstract: | The pressure compensating emitter, which have the advantages of constant flow under the change of pressure, anti-clogging and self-cleaning performance, has become the research hot point in the world. The compensating theory and structure of three kinds of pressure compensating emitters, namely on-line orifice emitters, in-line flat emitters and in-line cylindrical emitters, were e- valuated in this paper. The development trend of pressure compensating emitters was analyzed and some suggestion for improving study ability on pressure compensating of China was presented, too. |
