Abstract
The invention relates to an anti-scale check valve, which comprises a valve body, a valve seat arranged in the valve body, a central shaft, and a magnetic material arranged in the valve body, wherein a magnetic domain of the magnetic material acts on the surface of the central shaft. A low-intensity magnetic field with 10-50 Gauss acts on a part (the central shaft) needing to be anti-scale, so that scale prevention of the check valve can be ensured, and the performance of the check valve cannot be influenced. The check valve is simple in structure and good in sealing performance.
Description
Technical field
The invention belongs to the valve technology, relate in particular to a kind of scale protective type safety check that can prevent fouling in valve.
Background technique
Safety check in valve industry, major applications, in sewage, former water system, there will be more serious scale formation, the northern area of China especially, water quality meta-alkalescence, hardness are higher, and scale formation is even more serious.This type of incrustation scale is different from the fouling in the equipment such as high-temperature boiler, but the mode be similar to the mineral substance crystallization is attached on the central shaft of safety check, strong adhesion is difficult to remove, affect valve seal, cause the valve jam, increase the valve opening and closing moment of torsion, when serious, valve can't open and close and disabler.
At present commonly used and antiscaling method environmental protection is the magnetic water treatment technology, employing be the above high magnetic fields antiscale of 10000 Gausses, this high magnetic fields preventing fouling is applied on valve, high magnetic fields can have influence on the keying of valve, causes on the contrary the problems such as foreign material absorption.Therefore, for the antiscale that utilizes magnetic field to valve, also need further research, make the antiscale that can guarantee valve, can not affect again the performance of valve.
Summary of the invention
Purpose of the present invention is exactly for above-mentioned defect, and a kind of antiscale that can guarantee valve is provided, and can not affect again the scale protective type safety check of valve performance.
The technical solution adopted for the present invention to solve the technical problems is: a kind of scale protective type safety check is provided, comprise valve body, be located at valve seat and central shaft in valve body, also comprise the magnetic material be arranged in valve body, the magnetic field range of its magnetic material acts on the central shaft surface.
The described intensity that acts on the central shaft Surface field is 10～50 Gausses.
Described magnetic material is arranged on the central shaft surface.
Described magnetic material is embedded in exposed axle sleeve internal surface.
The described lip-deep magnetic material of central shaft that is arranged on is magnetic material layer.
The described magnetic material that is embedded in exposed axle sleeve internal surface is permanent magnet.
Compared with prior art, beneficial effect is in the present invention: act on 10～50 Gausses' low-intensity magnetic field at the position that needs antiscale (central shaft), can guarantee the antiscale of safety check, can not affect again the performance of safety check; Its check valve structure is simple, good seal performance.
The accompanying drawing explanation
The schematic diagram that Fig. 1 is scale protective type safety check of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
Antiscale safety check as shown in Figure 1, comprise valve body 301, be located at valve seat, the central shaft 302 in valve body and be arranged on the magnetic material in valve body, the component of its main fouling are central shafts 302, can cause the valve jam after central shaft 302 foulings, often cause valve to open, thereby cause valve function to lose efficacy.Therefore, the magnetic field range of magnetic material acts on the central shaft surface, simultaneously, and the low-intensity magnetic field that the intensity in magnetic field is 10～50 Gausses.
Magnetic material in the present embodiment can be arranged on the magnetic material layer on central shaft 302 surfaces, can be also the permanent magnet 303 that is embedded in exposed axle sleeve internal surface, and wherein, exposed axle sleeve is exposed axle sleeve in valve body.
Magnetic material layer can be adhere to, can be also to stick on the central shaft surface; Also can recessing in exposed axle sleeve, permanent magnet is fixedly mounted in this groove.
Make the low-intensity magnetic field that its magnetic intensity that reaches the central shaft surface is 10～50 Gausses.If magnetic intensity is lower than 10 Gausses, magnetic field can not magnetizing part a little less than too near medium, if magnetic intensity higher than 50 Gausses, magnetic intensity is too high affects valve opening and closing, cause the problem such as foreign material absorption.Make the axial water in center be subject to the Lorentz force effect in magnetic field, just, negative ion is respectively by left, right twisted helix shape orbiting motion, under its electrostatic attraction effect, interosculate, be combined into " solute molecule of dissolved state ", " solute molecule of dissolved state " separates out a large amount of small host crystal in water, in Crystallization Process, nucleus is constantly grown up, and the growth rate of crystal is less than nucleation rate, a large amount of micro crystals have been formed, and the structural stability of micro crystal, effectively reduce a plurality of micro crystals in conjunction with the probability that forms large crystalline solid, micro crystal finally becomes the incrustation scale of graininess, and it is more open to distribute, along with flowing of circulating water, lost the ability with wall absorption.Therefore, protect the surperficial non-scaling of central shaft 2, be unlikely to again to affect the start-stop performance of valve.
