    • A drip emitter is provided for delivering irrigation water from a supply tube to an emitter outlet at a reduced and relatively constant flow rate. Water enters the emitter through a first inlet and proceeds into a first chamber. When the water pressure is above a predetermined level, a one-directional valve opens to allow fluid flow past the first chamber, through a tortuous path flow channel, and through an emitter outlet. A second inlet is used to compensate for water pressure fluctuations in the supply tube to maintain output flow at a relatively constant rate. Water enters the second inlet and presses a flexible diaphragm toward a water metering surface to provide pressure-dependent control of the output flow. A copper member is mounted to the emitter over the emitter outlet to prevent plant root intrusion into the emitter outlet.
    • 提供滴水发射器,用于以降低且相对恒定的流速将灌溉水从供应管输送到发射器出口。 水通过第一入口进入发射器并进入第一室。 当水压高于预定水平时,单向阀打开以允许流体流过第一腔室,通过曲折路径流动通道,并通过发射器出口。 第二个入口用于补偿供应管中的水压波动,以保持输出流量相对恒定的速率。 水进入第二入口并将柔性隔膜压向测水表面,以提供对输出流量的压力依赖性控制。 铜构件通过发射器出口安装到发射器,以防止植物根侵入发射器出口。
