초록 ▼

The inlet to the water valve is provided with a resilient flow control device which deflects under pressure to reduce the inlet orifice and maintain substantially uniform flow. On the outlet side of the flow control the liquid is forced to turn at right angles to reach the multiple restricted orifices where the liquid again must turn 90°. At low pressures the flow is divided between 8 orifices 4 of which are gradually shut off by deflection of the flow control so at high inlet pressure the flow is divided among 4 orifices positioned in channels protecting them from being shut off by deflection of the flow control. The reduced velocity caused by the two 90°turns in flow results in substantial reduction of flow noise.

The combination with a water valve having a body provided with an inlet and a resilient centrally apertured flow control device mounted in the inlet and having a dashed downstream face and deformed by inlet pressure to provide generally uniform flow through the device with varying inlet pressure, of means for reducing the flow noise comprising, a partition in the inlet, downstream of the flow control device, having a blind hole therein in alignment with the central aperture of the flow control device surrounded by an annular surface which is engaged by the dished downstream face of the flow control device as the device deflects under inlet pressure, a plurality of first ports through the partition from said annular surface to the outlet side of the partition and subject to being closed off by said flow control device as the flow control device deflects against the annular surface, a plurality of grooves in said annular surface, one end of each groove communicating with said blind hole to receive flow passing through the flow control device under all flow conditions, and a plurality of second ports through the partition each located in one of said grooves remote from the blind hole and leading to the outlet side of the partition.
