Description

A kind of filter tap

Technical field

The utility model belongs to valve technology field, particularly relates to a kind of filter tap.

Background technique

Filter tap is used in industrial production and daily life in a large number, is used for the granule foreign of filtered fluid medium.Filter tap comprises elements such as valve body, valve gap, mistake filter core, and valve body includes inner chamber and arm of import and outlet.The someone has designed a kind of Filter valve [China Patent No.: ZL01220786.1 before this; Notice of authorization number: CN2472796Y], valve passage has the filter that is communicated as one, and filter has filter core.The sealing of the filter port of Filter valve is bolted on the filter by many with valve gap by analysis.Each clean or more renew cartridge all need spanner one by one bolt to be opened, integral valve cover is unloaded, removed filter core and cleaned, tighten one by one again after having cleaned.So promptly inconvenient, spended time is long again.

There is the people that the linkage structure at the filter port place of above-mentioned Filter valve is improved afterwards again, for example, the disclosed Magnetic filtration device valve of Chinese patent literature, [China Patent No.: ZL200420096170.6; Notice of authorization number: CN2728596Y], by valve gap, seal ring, connecting base, filter screen, tiltedly valve-rod body etc. is formed, tiltedly the top of valve-rod body is connected with valve gap by screw thread, between oblique valve-rod body and the valve gap seal ring is arranged.Tiltedly valve-rod body and valve gap are compared the time that will spend with previous document by being threaded shortening, but particularly on the production line or need to use apparent inconvenience and lose time under the environment of frequent cleaning and filtering core.

Summary of the invention

The purpose of this utility model is the problems referred to above that exist in the existing technology, and proposed a kind ofly can to dismantle that filter core just can be realized cleaning, high working efficiency, filter tap rational in infrastructure.

The purpose of this utility model can realize by following technical proposal: this filter tap, comprise valve body, on valve body, has a blow down branch that communicates with body cavity, in blow down branch, be provided with one and cross filter core, be provided with a valve gap that pressed filter core in the port of blow down branch, it is characterized in that having a sewage draining exit on the described valve gap, the sewage draining exit place is provided with a Sealing.

This filter tap is connected in the flowing medium pipeline, and blow down branch and valve body are inclined to set, and crosses filter core and installs with the angle of inclination of blow down branch, and valve gap is pressed on body cavity crossing filter core.The port of blow down branch is provided with valve gap and is located at the effect that sealing configuration on the valve gap sewage draining exit plays the shutoff blow down branch.Open sealing configuration, flowing medium can discharge the impurity that accumulates by sewage draining exit, cleaned up filter core after, close above-mentioned sealing configuration.

At above-mentioned filter tap, described Sealing is provided with a seal plug for the sewage draining exit at valve gap, and described seal plug is by the valve gap that is threaded.Be threaded and made things convenient for the replacing of seal plug; After impurities accumulation arrives to a certain degree, turn on seal plug, impurity can discharge by sewage draining exit, thereby makes things convenient for despumation and cleaning and filtering core.

At above-mentioned filter tap, described Sealing is provided with a valve for the sewage draining exit at valve gap.After impurities accumulation arrived to a certain degree, it was more particularly to produce impurity at production line, needed under the situation of frequent cleaning and filtering core, as long as open external valve, impurity can discharge by sewage draining exit, thereby has made things convenient for despumation and cleaning and filtering core, also save time, enhance productivity.

At above-mentioned filter tap, the end of described valve gap is provided with a positioning seat one that is used to press filter core.Filter core was pressed in the bottom surface of positioning seat one, and filter core was close in the side.

At above-mentioned filter tap, described body cavity has the positioning seat two that is complementary with valve gap.Cross the filter core two ends and be installed in respectively in the positioning seat, made filter core more firm, be difficult for rocking.

Compared with prior art, this filter tap is owing to have a sewage draining exit on valve gap, and realization need not be dismantled bottom flange just can realize the cleaning and filtering core, has saved the production time, has improved working efficiency; Advantages such as the filter tap of this structure is rational in infrastructure, easy to use, long service life.
