Straight-through type filter device

Abstract

The invention discloses a straight-through type filter device. The straight-through type filter device is vertically arranged in front of a water feeding pump used for supplementing water to a boilerand comprises a straight barrel and a filter element, wherein the upper end of the straight barrel is an inlet end, and the lower end of the straight barrel is an outlet end; the filter element is conical and is provided with a conical top end and a conical bottom end in an axial direction; a plurality of filter holes are formed in the conical side wall of the filter element; the filter element isarranged in the straight barrel; and the conical top end faces the inlet end, and the conical bottom end is matched with the outlet end. The straight-through type filter device is low in fluid resistance, high in filtering precision and good in filtering effect.

Description

technical field [0001] The invention relates to the technical field of pipelines, in particular to a straight-through filter device. Background technique [0002] Boiler replenishment requires a feed water pump to send demineralized water into the boiler. A feed water filter is required before the feed water pump. The forced circulation boiler is also equipped with a hot water circulation pump. The inlet of the circulation pump is equipped with a circulating water filter. The above filter is configured before the pump. , to prevent particulate impurities from entering the pump and causing damage to the pump. [0003] Filter, also known as decontamination device and filter valve, is an indispensable device for the pipeline system of conveying medium. [0004] Filters suitable for the above occasions, such as figure 2 As shown, most of the Y-type filters 100 that are directly available on the market are Y-shaped. The Y-type filter 100 has low filtration precision and large ...

AI Technical Summary

Problems solved by technology

[0006] The filter element of the current Y-shaped filter 100 is installed from the oblique outlet 202, and the flow area of ​​the fluid flow filter element only accounts for a part of the filter element, so there is a problem that the actual flow cross-sectional area is small, resulting in the flow resistance of the fluid through the filter. Big

At the same time, in order to prevent excessive resistance, the filter holes on the filter element are relatively large, resulting in low filtration accuracy of the filter.
