A braided strainer for a draw line, and method of forming same. The strainer comprises a frame in the form of a pair of spaced planar plates, one being a solid end plate and the other having a control aperture. A plurality of spaced, parallel rods of similar length are positioned near the peripheries of the plates and secured and extending between the plates. A plurality of cylindrical walls of braided strands of strainer medium, are provided, the braided cylindrical walls having similarly spaced rod-receiving holes extending longitudinally in spaced fashion through the strands of strainer medium. These walls are contiguously stacked on the plates to extend between them. The plate having the central aperture permits flow of fluid drawn through the cylindrical walls during operation of the strainer. That plate has associated with it a connector to releasably secure the strainer to a mating connector on a free end of the draw line.
A method of forming a strainer for a draw line, said strainer comprising an outer strainer wall defining an enclosed interior space, said method comprising the steps of:
A method of forming a strainer for a draw line, said strainer comprising an outer strainer wall defining an enclosed interior space, said method comprising the steps of:
A strainer for a draw line comprising an outer strainer wall defining an enclosed interior space and a frame for supporting said wall, said frame comprising a base and a cap spaced apart from each other by an array of parallel rods defining the position of said strainer wall, said rods having axially extending fluid deflecting ribs on their surfaces, at least one of said base and cap having an opening therein in communication with said interior space to receive and connect with a draw line, said strainer wall comprising at least one elongate strand of filter medium comprising a plurality of individual strands braided together, said filter medium having opposed lateral surfaces and array of openings extending between said lateral surfaces spaced to receive said rods, said braid being threaded onto said rods through said openings to define said filter wall.
A strainer for a draw line comprising an outer strainer wall defining an en-closed interior space and a frame for supporting said wall, said frame comprising a base and a cap spaced apart from each other by an array of parallel rods defining the position of said strainer wall, said rods including at one end thereof a bulbous member for fitting within a similar shaped opening within said base to provide relative movement therebetween, at least one of said base and cap having an opening therein in communication with said interior space to receive and connect with a draw line, said strainer wall comprising at least one elongate strand of filter medium comprising a plurality of individual strands braided together, said filter medium having opposed lateral surfaces and array of openings extending between said lateral surfaces spaced to receive said rods, said braid being threaded onto said rods through said openings to define said filter wall.
