Abstract
The invention provides a one-piece self-cleaning filter. A filter screen is inclinedly arranged in a valve body, and a valve cover is welded with the valve body, wherein the caliber of a pipeline of a filter screen section is twice the diameter of the filter, and a discharge pipeline is arranged on the bottom of the filter screen section. When a medium flows into the filter, impurities in the medium are filtered by the filter screen, and the filtered-out impurities flow out; because the filter screen is inclinedly arranged, the impurities precipitate on the bottom of the filter section and are not attached to the filter screen, and meshes of the filter screen are always kept clear; the pipeline of the filter section is relatively large to house more impurities; when the impurities precipitating on the bottom of the filter section need to be cleaned up, the discharge pipeline is opened and the impurities are discharged. The filter has the advantages of advanced structure, convenient installation and clean, large impurity carrying capacity, low resistance, and convenient impurity discharge. The filter is mainly used for filtering in the industries such as water supply and drainage, heating and ventilating, industry, agriculture, electronics, medicine, building, steel, metallurgy and papermaking.
Description
Technical field
Be a kind of integral type self-cleaning filter, can be generally applied in HVAC and plumbing industry.
Background technology
Filter, is arranged on the entrance point of pressure-reducing valve, relief valve, Valve for keeping constant water level or miscellaneous equipment conventionally, is used for removing the impurity in medium, to protect the normal use of valve and equipment.Meanwhile, because common y-type filter easily causes foreign material to block screen pack and needs to take out filter screen, remove foreign material, cumbersome, this just need to a kind ofly be not easy to cause foreign material to block the self-cleaning filter of screen pack.
Summary of the invention
Content of the present invention is: the principle in conjunction with y-type filter is improved, and invents a kind ofly can not cause foreign material to block filter screen, and foreign material are automatically concentrated and do not needed to take out screen pack and the self-cleaning filter of removing foreign material.
The technical solution adopted for the present invention to solve the technical problems is: in tapered pipeline, place a screen pack, screen pack and pipeline journey certain angle, be beneficial to medium by filter screen impurity, be blocked and be automatically deposited to bottom, in bottom, place in addition a blow-off line, for discharging impurity, need not take out screen pack.
The invention has the beneficial effects as follows: resistance is little, the impurity in medium can not be attached on screen pack; Pollutant holding capability is large, because a segment pipe of placement screen pack is larger than place pipe network bore, can hold more impurity; Blowdown is convenient, opens the blow-off line of bottom and just can discharge foreign material.
Accompanying drawing explanation
Fig. 1 is that medium enters filter from valve gap end, and the screen pack of filter interior filters medium, is blocked the contamination precipitation that gets off in filter bottom, medium after filtration flows out, when needs are cleared up impurity, open the blow-off line of filter bottom, just can discharge impurity.
In figure: 1, valve body, 2, valve gap, 3, screen pack.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
In Fig. 1, first screen pack is tilted to put into valve body (1), then valve body (1) and valve gap (2) welding.Due to the structure of this filter, the caliber of fillter section is the twice of filter latus rectum, so enter filter when medium, screen pack (3) can not increase the resistance of medium and play the effect of filtration, and can hold more impurity; Because screen pack (3) tilts at an angle, the contamination precipitation being filtered, in valve body (1) bottom, can not be attached to the filter efficiency that has guaranteed screen pack (3) on screen pack (3); When need to clear up in filter impurity time, open the blow-off line of valve body (1) bottom, discharge impurity.
Claims (4)
1. an integral type self-cleaning filter, comprise valve body, valve gap and screen pack, described screen pack tilts to be placed in valve body, then by valve gap and valve body welding, it is characterized in that, when medium flows into, screen pack impurity screening, the medium after filtration flows out, because screen pack is slant setting, impurity can be deposited in duct bottom and not be attached on screen pack, and the pipeline of fillter section is larger, can hold more impurity dirt; Fillter section duct bottom is placed with blow-off line, in the time of need to clearing up impurity, opens blow-off line and just can discharge impurity dirt.
2. according to right, state the valve body of asking described in 1, it is characterized in that, valve body is comprised of three pipelines, the fillter section pipeline of placing screen pack is connected by eccentric reducer with filter drift diameter pipeline, flange is placed at valve body two ends, because fillter section pipe diameter is the twice of this filter latus rectum, this filter can be crossed and hold more impurity dirt.
3. according to right, state the valve body of asking described in 1, it is characterized in that, valve body fillter section bottom is placed with a pipeline, and bore is 1/2 to 1/3 of this filter latus rectum, and this pipeline is blow-off line, and main discharge is filtered the impurity dirt herein that is deposited on that net filtration gets off.
4. according to right, state the screen pack of asking described in 1, it is characterized in that, there is the screen pack of certain specification mesh through processing, place inlet valve body and with its laminating, due to screen pack slant setting, make above impurity is not easy to be attached to, to keep the unimpeded of mesh, reduce the resistance of medium and play the impurity concentrated effect of precipitation automatically.
