METHOD OF INCREASING EFFICIENCY OF A Y STRAINER AND A Y STRAINER

摘要

A method of increasing efficiency of a Y strainer and Y strainer modified in accordance with the method. The Y strainer is of the type that has a filter cartridge receiving inflow through one end and outflow through apertures in a peripheral sidewall. The method involves slowing a velocity of fluids entering the filter cartridge of the Y strainer by having the fluids pass from a first bore of a first diameter into a second bore of a second diameter which is at least 50% larger than the first diameter prior to entering the filter cartridge. The filter cartridge also has the second diameter. This modification has been found to dramatically improve the performance of the Y strainer.
