Abstract
The utility model discloses a self-exhausting once-through filter, which comprises a water inlet, a shell, a filter screen, a water outlet, a sewage outlet and an air outlet valve, wherein the filter screen is arranged in the central portion of the shell, the sewage outlet which is used for cleaning filtering slag deposition is arranged on the lower portion of the shell in front of the filter screen, the air outlet valve is arranged on the upper portion, and the self-exhausting once-through filter can automatically exhaust air which is gathered in the filter cavity and can eliminate the negative pressure of pipelines.
Description
Technical field
The utility model relates to a kind of water filter, specifically, relates to a kind of from exhaust through type filter.Be mainly used in the water filtration of various water supply lines.
Prior art
Existing through type filter is in order to reach enough area of passages, and the area of section that filters pipeline section is all greater than the area of section of entery and delivery port, and this has caused microbubble and the Water Soluble Gas in the water constantly to be assembled in this part, has a strong impact on the water application efficiency of pipeline.
Summary of the invention
The utility model provides a kind of from exhaust through type filter at existing problem in the prior art, and its compact conformation, easy for installation can be discharged the gas of assembling in the filter chamber automatically.
The technical solution of the utility model is: a kind of from exhaust through type filter, comprise water inlet, housing, sewage draining exit, filter screen, delivery port, air bleeding valve.
Described housing middle part is provided with filter screen, and the lower housing portion before filter screen is provided with sewage draining exit, on top air bleeding valve is set.
The utility model is from exhaust through type filter, and described housing is cylindric, and filter screen is circular, is provided with air bleeding valve, sewage draining exit on housing.
During work, water enters housing by water inlet, strainer filtering in housing, remove particle, impurity in the water, flowed out by delivery port then, after filtering a period of time, the dirt that screen pack adheres to is more or when filter is not worked, the bottom that accumulated slag on gravity effect lower filter screen is fallen housing can be discharged by sewage draining exit; Microbubble in the water and Water Soluble Gas are after housing top gathers to a certain degree, and the upper end air bleeding valve can be opened discharge gas automatically.Avoid because the gas accumulation affects arrives pipeline efficient.And excessive at pipeline front end water, when causing the pipeline negative pressure, air bleeding valve is opened automatically, effectively suppresses the generation of negative pressure.
Compare with existing filter, the utlity model has following advantage:
1, easy for installation, on the basis that guarantees filtration, save the space that air bleeding valve is installed separately in the pipeline.
2, automatic vent effectively guarantees pipeline water delivery efficient.
3, can suppress the generation of negative pressure in the pipeline effectively.
Description of drawings
Fig. 1 is that the utility model is from exhaust through type structure of filter schematic diagram.
