TOILET FILL VALVE WITH IMPROVED NOISE ABATEMENT |
摘要 |
<p>A toilet fill valve includes a housing defining a water fill passage and a water inlet. A valve disposed in the passage divides the housing into a upstream portion and a downstream portion. A pressure regulator vertically oriented in the downstream portion of the housing has a spiral configuration providing a significant pressure drop in the water flow. Noise abatement is enhanced by pressure regulation which reduces the flow velocity, flow directors which inhibit turbulence, and energy drops provided in a downspout.</p> |
