Abstract

The utility model relates to a filter with a flange. The filter with the flange is characterized by comprising a shell, a flange cover and a filter, wherein one end of the shell is connected with the flange cover; the shell is internally provided with the filter; the filter is pressed tightly on a support element through an inlet pressing element and an end part pressing element; the tail end of the end part pressing element is connected with a sewage discharge pipe; the filter comprises coarse filter cotton, active carbon and fine filter cotton; a baffle net is arranged between the coarse filter cotton and the active carbon; and a baffle net is arranged between the active carbon and the fine filter cotton. The filter with the flange has the advantages that the filter with the flange is beneficial to preventing adverse influences of flowing disturbance on the measurement accuracy of a flow meter, the filter is convenient to install, is simple in structure, is convenient to use, has long service life, and is simple to manufacture.

Description

A kind of filtrator that has flange

Technical field

The utility model relates to a kind of filtrator, relates in particular to a kind of filtrator that has flange.

Background technology

Generally the Upstream section at flow measurement instruments such as water meters adds filtrator, in order to avoid impurity causes the flow detecting element of measurement instrument and damages or metering is lost certainly in the pipeline, most flowmeters detect flow to measure fluid velocity; Speed is that vector has size and Orientation, and measuring accuracy is high when fluid is in laminar flow, if produce flow disturbance; Cause velocity field unusual, measuring accuracy descends, and fluid flows in pipeline; During through filtrator, stopped by filter screen, flow disturbance is more serious; Can obviously influence measuring accuracy, for addressing the above problem, the spy provides a kind of new technical scheme.

The utility model content

The purpose of the utility model provides a kind of filtrator that has flange.

The technical scheme that the utility model adopts is:

A kind of filtrator that has flange comprises housing, blind flange and filtrator, and said housing one end is connected with blind flange; Be provided with filtrator in the said housing; Said filtrator is pressed on the support member through import compressing member and end compressing member, and the tail end of said end compressing member is connected with blow-off pipe, and said filtrator comprises coarse filtration cotton, activated charcoal and thin filter cotton; Be provided with backstop between said coarse filtration cotton and the activated charcoal, be provided with backstop between said activated charcoal and the thin filter cotton.

Be fixedly connected through nut between said housing and the blind flange.

The utility model has the advantages that: help avoiding flow disturbance that the flowmeter survey precision is caused harmful effect, filtrator is easy for installation, and is simple in structure, easy to use, and long service life is made simple.
