Abstract:
A piping apparatus is provided, which comprises a strainer comprising a strainer housing including a strainer branch; wherein the strainer housing includes one or more pressure sensors; wherein, when a strainer element is in the strainer branch, at least one pressure sensor of the plurality of pressure sensors is fixed to the strainer housing at a location upstream of the strainer element and/or is fixed to the strainer housing at a location downstream of the strainer element.
Abstract:
Duplex fluid strainers, systems and methods are provided, and include a housing with a first valve chamber defining an inlet port, a first port, and a second port, and a second valve chamber defining a third port, a fourth port, and an outlet port. The first and third ports communicate with a first strainer chamber, and the second and fourth ports communicate with a second strainer. A first seal assembly includes a first disk movable within the first valve chamber into sealing engagement against either of the first port or the second port, and a second seal assembly includes a second disk movable within the second valve chamber into sealing engagement against either of the third port or the fourth port.
Abstract:
A water distribution system including a water storage tank, a water treatment unit, a diverter valve, and interconnecting water conduits arranged so that the same water treatment unit can be used to treat water supplied from a fill port to the storage tank during a fill operation, as well as water leaving the storage tank for supply to one or more points of water use during a supply operation. A diverter valve is provided which is movable between a fill position wherein the water treatment unit is in fluid communication with the fill port and not the point of water use device, and a supply position wherein the water treatment unit is in fluid communication with the at least one point of water use device and not the fill port. When the diverter valve is in the fill position, water supplied to the fill port can thus flow through the diverter valve and to the water treatment unit for treatment then to the storage tank for storage. When the diverter valve is in the supply position, the water from the storage tank can be delivered using means for pressurizing water to the same treatment unit for treatment, then through the diverter valve and to the at least one point of water use device.

Abstract:
A modular filter system using replaceable filter cartridges includes a mounting bracket for each filter cartridge and corresponding filter head that includes keyed attachment of the head to the mounting ring on the mounting bracket and modular attachment of the mounting bracket to the modular back plate. Back plates are also modular to permit assembly of a variety of multi-cartridge systems.
Abstract:
Regeneration of water treatment media is disclosed which includes a water treatment unit having one or more media therein, and which upon initiation of flow of the water, imparts turbulence and abrasion to the treatment medium to automatically cleanse the medium of light solid contaminants, as well as contaminant coatings on the media. This greatly improves the operation of the media and extends its life. In addition, the water treatment unit disclosed may simply be rotated through any one of a number of positions between service, backwash, flush, off, and/or bypass operational modes for further regeneration of the treatment media.
Abstract:
A dual filter isolation block for isolating a fluid stream between a fluid source and a user device and including a main body, a first fluid path provided in the main body between the source and the user device and a first filter provided in the first fluid path. A second fluid path is also provided in the main body between the source and the user device and a second filter is included in the second fluid path. A pair of spools are slidably disposed in the main body and intersect the first fluid path and the second fluid path, respectively, for selectively isolating the first fluid path and the first filter from the second fluid path and the second filter. In a specific application the dual filter isolation block selectively isolates a pair of filters for filteringg an operating fluid such as hydraulic oil or fluid between an actuator and a servo valve to protect the servo valve from contaminants in the operating fluid. The filters are each designed for separate removal and replacement while the hydraulic fluid flows through the other filter, to avoid interrupting operation of the user device. A method for maintaining a flow of operating fluid between a fluid source and a user device while continuously filtering the operating fluid is also included.
Abstract:
A water filtering apparatus with water flow switch valve device includes a water container filled with filtering materials and a switch valve device. The switch valve device includes a valve seat, a split valve, a control rod, and a valve cover. The valve seat is provided with threaded holes for connection with water pipes. The split valve has an interior divided into two isolated and non-communicating chambers. The outer wall of the split valve enclosing the chambers is provided with spaced water holes. When the split valve is installed in the valve seat and the valve cover is assembled to the valve seat, the split valve may be used to control the direction of flow of water into the water container for purposes of filtering water or purging the water container.
Abstract:
A deep oil fryer and filtration system is disclosed wherein the filtration system (B) is disposed within a cabinet (16) of a deep oil fryer (A) having a plurality of vats (10, 12, and 14). Filtration system (B) includes a drawer having a reservoir (20) and an adjacent utility compartment (40). A pre-filter (34) is disposed in a filter basket (30) received in reservoir (20) and spaced above a bottom wall of a reservoir by the legs (32). A drain outlet (28) from the reservoir delivers cooking oil to a pump (70). A flow line system which minimizes retention of cooking oil in the lines includes a reservoir outlet line (74), a filter inlet line (78), a filter by-pass line (80), and a return line (86). Whenever by-pass valve (82) is open and pump (70) is on, pre-filtered oil from filter (36) passes through filter inlet (50) and exits filter outlet (64) without passing through a filter element ( 48) to preheat the filter. The by-passed oil is returned to the cooking vat for rinsing out the cooking vat. When by-pass valve (82) is closed, oil entering filter inlet (50) is forced through filter element (48) on both ends (54a) and (56a). Primary filter (C) is a pressure filter which provides a final filtration of the prefiltered oil. Advantageously, pressure filter (C) includes an end cap (46) which is removable so that filter element (48) may be replaced from an opening in the oil reservoir to obtain any spillage.
