| 摘要 |
The present invention provides an in-line fluid emitter facilitating a controlled flow of fluid from a pipe in which the emitter is disposed. The emitter includes the following features: (1) a hollow generally cylindrical emitter body, with a plurality of openings defined in the emitter body to facilitate the flow of fluid therethrough; (2) a pressure compensating, resilient valve mounted in the emitter body; (3) a first passage defined in the emitter body directing the fluid from the openings to the valve; (4) an exit flow region defined in the emitter body, the exit flow region being in fluid connection with the output of the valve to receive fluid that has passed through the valve; and (5) a pair of annular sealing rings, one of which is disposed to a distal side of the openings, and the other of which is disposed to a distal side of the exit flow region, to seal the area between the pipe and the emitter.
