The specific embodiment

By reference to the accompanying drawings, the utility model is described in further detail.

As shown in the figure, the utility model magnetic filter is characterized in that: described filter includes a housing 1, and it is comprised of main body and 2, lid, and both are screwed in together, and seal with plastic washer 28, on housing 1, also are provided with draining valve 6; An entrance 15 and a main body 16 are arranged on the main body of described housing 1, a magnetic shaft is arranged on the inside of housing 1, sleeve 9 is round magnetic shaft; Blow vent 4 in described lid 2 includes a bell tap 22 and a main body, and an O shape ring 25 is arranged between magnetic shaft and blow vent 4.Described magnetic shaft can be the tubular products 17 of a hollow, and a plurality of magnet 18 and magnetic pole 19 are contained in its inside, forms magnetic field, magnet 18 and magnetic pole 19 both alternative arrangements of a pipeline.The terminal of described tubular products 17 has a stainless steel plug 20 to seal.Described round handle 21 control inner shaft move up and down and make inner passage open or close.On described passage 4, be provided with rubber 1 and rubber 2 24, be provided with element 3 between magnetic shaft and passage 4.On described filter, also be provided with plastic washer 1 and plastic washer 28.

As shown in the figure, overall structure of the present utility model as indicated earlier.As shown in Figure 1, housing 1 is made by mold injection, and its profile can be different shape.This filter is specifically designed to heating system at boiler, and radiator is combined between valve and some other water heating fittings and with pipeline.Due to it, for hot-water heating system, answer the material of this housing 1 can bear the temperature of 100 degree and deformation does not occur.Generally, the temperature of fluid can not arrive so high temperature.In addition, the entrance on housing 1 15 and outlet 16 are made by metal die.Entrance 15 and outlet 16 are all that 3/4 " the BSP pin thread can be fixed on other parts by it, as the copper valve of heating system.Inner structure is generally cylindricality, like this can so that fluid along the path flows of rotation.Its inner surface should be level and smooth, can reduce like this obstruction of liquid flow.At housing entrance 15 places, a screwed hole is arranged, this is a passage, is filtered dry to guarantee air, a magnetic shaft is arranged in the inside of housing 1, magnetic element is fixed to and covers on 2, and blow vent 4 is screwed to bottom along axis, then by plastic washer one 7 sealings, avoids leaking.Plastic washer 1 and plastic washer 28 are to be made by silicon rubber, nontoxic in heating system, environmental protection.

As shown in Figure 3, stainless steel plug 20 can prevent the magnet contact of inside, waters.Magnet 18 and magnetic pole 19 are positioned at inner alternative arrangement.Two adjacent magnet relative directions are placed.The principle of magnetic characteristic is the magnet that the magnet of the South Pole and the arctic does not comprise north and south poles.When two magnet are put together, the magnetic line of force will change its original direction, by magnetic force nearly all on surface on tubular products 17.But when radial distance increases, magnetic force will reduce rapidly.Like this, should in the design plastic fuselage, consider that separator is in the axle of filter and the effect on magnetic flux.

When in application, water is 10 inflows from entrance 16 around magnetic shaft, then by outlet 15, flow out.Ferrous particle and mud in liquid can be adsorbed to stainless steel pipe surface under the effect of magnetic force.Sleeve 9 is convenient to clear up mud around magnetic shaft 10, and it can be put back to and reuses.Thin plastic sleeve 9 also can affect magnetic field intensity.In described lid, the extension of the axle of the blow vent 4 in lid 2 is fixed on magnetic shaft.As shown in Figure 4, round handle 21 control inner shaft move up and down and make inner passage open or close.When bar during at upside, rubber 24 leaves valve and produces certain space and form passage.When bar rubber contact valve and passage during in lower end.Rubber 1 and rubber 2 24 make the more reliable performance of blow vent, when producing the heat hydraulic pressure, have avoided the appearance of leakage problem.Blow vent 4 is fixed by screw thread with magnetic shaft.Two borings on magnetic shaft have produced a passage in enclosure interior in addition.

O shape ring 25 is set between magnetic shaft and blow vent 4 be for Leakage prevention.A groove is arranged be used to keeping O shape ring 25 to be in stable position in crooked main body, prevent from when himself is on being fixed to magnetic rod being scratched by screw thread.This structure is more stable in the environment of water is arranged.The acting as of element 3 can increase with the contact area of blow vent 4 and make to cover 2 aesthetic in appearance.During by sludge removal, lid 2 is positioned at the magnetic rod place with blow vent 4 when needs, and plastic sleeve 9, element 3 can screw down from main body.When sleeve 9 is taken off from magnetic rod, around sleeve 9, just no longer include the ferrous attraction of magnetic attraction on surface, the collection of mud more for convenience.

When cleaning operation, lid 2 is screwed back to original position, have and introduce the danger of a certain amount of air to housing, airborne oxygen is unfavorable for pipe-line system, should in this blow vent 4, be necessary to add a certain amount of chemical dose to make System Operation normal.Identical at the structure of the draining valve 6 of porch and blow vent 4, but the screw thread of different size is arranged.When this system not in use, by round handle 21, unclamp draining valve 6, the water in housing can be discharged by bell tap 22 places, keeps housing to be in drying regime.In use, this equipment can vertically install also can be horizontally installed with ball valve and other part.
