摘要： A flow control includes a conduit and a flow control washer disposed in the conduit between the conduit's inlet and the outlet. A gas inlet passage opens into the conduit, preferably at a location just downstream of the flow control washer, to permit a gas (typically ambient air) to enter a liquid stream flowing through the flow control washer. The admission of a gas into this liquid stream reduces noise generated by liquid flow through the flow control washer. Gas induction and noise reduction capabilities may be enhanced by admitting the gas fluid into a low pressure region of a venturi located in the conduit downstream of the flow control washer. The flow control is particularly useful in a wastewater drain of a water softener control valve, but is also useful in a variety of other applications. A method of reducing noise in a flow control is also provided.

摘要： A seal stack, configured for supporting, guiding, and sealing a piston of a water softener control valve or the like, can be preassembled prior to its insertion into the associated valve bore and compressed after it is inserted into the bore. This post-assembly seal stack compression assures reliable assembly of the seal stack, facilitates valve assembly and disassembly, and negates the need to hold tight tolerances in bore diameter design and seal diameter design. The seal stack includes a plurality of static seals, a plurality of dynamic seals which are either combined with or separated from the static seals, and a plurality of spacers that support the seals. Each of the static seals is disposed between two adjacent spacers and seals against a peripheral surface of the bore, and each of the dynamic seals is disposed between two adjacent spacers and seals against the piston. Each of the spacers is connected to an adjacent spacer by a lost motion connector that permits limited axial movement therebetween and axial compression of the seal stack when the seal stack is assembled into the bore. Each of the static seals compresses axially and expands radially upon axial compression of the seal stack to enhance the sealing contact between the static seals and the peripheral surface of the bore.
