Abstract
The utility model provides an integrated self-cleaning filter. The filter is characterized in that a filter net is obliquely placed in a valve body; a valve deck is welded together with the valve body; the caliber of a pipeline of a section on which the filter net is placed doubles the diameter of the filter; and a blow-off pipeline is placed at the bottom of the section. When media flow in, the filter net filters impurities in the media, and the impurities after filtration flow out. As the filter net is obliquely placed, the impurities are precipitated at the bottom of the filter section and are not attached to the filter net, so that the meshes of the filter net are kept unblocked all the time. The pipeline of the filter section is bigger and can contain more impurities and dirt. When the impurities precipitated at the bottom of the filter section need to be removed, the blow-off pipeline is opened to discharge the impurities. The filter has the advantages of advanced structure, convenience in installing and washing, high dirt containing capacity, low resistance, convenience in blow-off and the like, and is mainly used for filtration in the industries such as water supply and drainage, heating and ventilation, industry, agriculture, electronics, medicine, construction, iron and steel, metallurgy, papermaking and the like.
Description
Technical field
Be a kind of integral type self-cleaning filter, the energy widespread usage is on HVAC and plumbing industry.
Background technology
Filter is installed in the entrance point of pressure-reducing valve, relief valve, Valve for keeping constant water level or miscellaneous equipment usually, is used for removing the impurity in the medium, with the normal use of protection valve and equipment.Simultaneously, remove foreign material owing to common y-type filter causes foreign material to block screen pack easily and needs to take out filter screen, cumbersome, this just need 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 out a kind ofly can not cause foreign material to block filter screen, and foreign material are concentrated automatically 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: described integral type self-cleaning filter is made up of valve body, valve gap and screen pack, valve body and valve gap welding; Valve body is welded to form by blowdown section, reducer and outlet section, and blowdown segment pipe bore is that 2 times of outlet section pipeline are big, is conducive to hold more impurity; The blowdown section bottom of valve body is placed with sewage draining exit, and bore is 1/2 to 1/3 of port of export pipeline, opens sewage draining exit and just can discharge foreign material, and blowdown is convenient; Screen pack tilts to be placed in the filter, reduced diameter portion on valve body and the valve gap is screen pack fixedly, screen pack and filter interior are fitted, screen pack tilts to place, impurity kept off down and the sewage draining exit of putting together near, be beneficial to blowdown, screen pack tilts in addition, makes impurity be not easy to stick to and makes the filter efficiency of filter better on the screen pack.
The invention has the beneficial effects as follows: resistance is little, and the impurity in the medium can not be attached on the screen pack; Pollutant holding capability is big, because it is bigger than place pipe network bore to place a segment pipe of screen pack, can hold more impurity; Blowdown is convenient, opens the blow-off line of bottom and just can discharge foreign material.
Description of drawings
Fig. 1 is that medium enters filter from the 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 the filtration flows out, when needs cleaning impurity, open the blow-off line of filter bottom, just can discharge impurity.
Among the figure: 1, valve body, 2, valve gap, 3, screen pack, 1-1, blowdown section, 1-2, reducer, 1-3, the port of export, 1-4 sewage draining exit.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
In Fig. 1, earlier screen pack is tilted to put into valve body (1), valve body (1) and valve gap (2) welding then.Because this structure of 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 that is filtered can not be attached to the filter efficiency that has guaranteed screen pack (3) on the screen pack (3) in valve body (1) bottom; When the impurity in the needs cleaning filter, open the blow-off line of valve body (1) bottom, discharge impurity.
Claims (4)
1. integral type self-cleaning filter, comprise valve body, valve gap and screen pack, it is characterized in that, described valve body and valve gap welding, valve body is welded to form by blowdown section, reducer and outlet section, the blowdown section bottom of valve body is placed with sewage draining exit, and screen pack tilts to be placed in the filter, and screen pack and filter interior are fitted.
2. state according to right and ask 1 described integral type self-cleaning filter, it is characterized in that described valve body is welded to form by blowdown section, reducer and outlet section, blowdown segment pipe bore is that 2 times of outlet section pipeline are big.
3. state according to right and ask 1 described integral type self-cleaning filter, it is characterized in that, the blowdown section bottom of described valve body is placed with sewage draining exit, and bore is 1/2 to 1/3 of port of export pipeline.
