Description
Technical field
The utility model belongs to valve technology, relates in particular to a kind of scale protective type eccentric half-ball valve that can prevent fouling in valve.
Background technique
Eccentric half-ball valve 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 be similar to spherical crown and the valve seat that is attached to eccentric half-ball valve in the mode of mineral substance crystallization, strong adhesion is difficult to remove, affect valve seal, cause valve jam, increase valve opening and closing moment of torsion, when serious, valve cannot open and close and disabler.
At present antiscaling method conventional and environmental protection is magnetic water treatment technology, employing be high magnetic fields antiscale more than 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 utilizing magnetic field also to need further research to the antiscale of valve, make to guarantee the antiscale of valve, can not affect again the performance of valve.
Summary of the invention
The purpose of this utility model 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 eccentric half-ball valve of valve performance.
The utility model solves the technological scheme that its technical problem adopts: a kind of scale protective type eccentric half-ball valve is provided, comprise valve body, be located at valve seat in valve body, form the spherical crown of sealing pair with valve seat and support the spool of spherical crown, also comprise the magnetic material being arranged in valve body, the magnetic field range of its magnetic material acts on spherical crown surface.
The described intensity that acts on spherical crown Surface field is 10～50 Gausses.
Described magnetic material is arranged on spherical crown surface.
Described magnetic material is arranged on spool and spherical crown surface of contact position.

Compared with prior art, beneficial effect is the utility model: at the position that needs antiscale, (spherical crown surface) acts on 10～50 Gausses' low-intensity magnetic field, can guarantee the antiscale of eccentric half-ball valve, can not affect again the performance of eccentric half-ball valve; Its eccentric half-ball valve is simple in structure, good seal performance.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model scale protective type eccentric half-ball valve.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Scale protective type eccentric half-ball valve as shown in Figure 1, comprises valve body, is located at valve seat 203 in valve body, forms the spherical crown 201 of sealing pairs with valve seat 203 and supports the spool 204 of spherical crown 201, and the component of its main fouling are spherical crown 201 and valve seat 203.Once spherical crown 201 and valve seat 203 foulings, change valve seal and coordinate when dirt layer is thin, increase valve opening and closing moment, causes spherical crown 201 and valve seat 203 rapid wears, reduces life of valve, during dirty bed thickness, even cause that spherical crown and valve seat adhesion valve cannot open.Therefore, be also provided with magnetic material in valve body, the magnetic field range of its magnetic material acts on spherical crown 201 surfaces, and meanwhile, the intensity that acts on spherical crown 201 Surface fields is 10～50 Gausses.
Magnetic material in the present embodiment can be arranged on the lip-deep magnetic material layer of spherical crown 201, also can be arranged on the permanent magnet 202 of spool 204 and spherical crown 201 surface of contact positions, and its permanent magnet 202 is in full closeding state.
Magnetic material layer can be to adhere to, stick in spherical crown 201 outer surfaces; Single permanent magnet can be fixedly mounted in the groove of central position on spool 204 surfaces, can be also a plurality of permanent magnets along even circumferential distribute or non-uniform Distribution in be fixedly mounted in the groove of marginal position on spool 204 surfaces; Also can have for the groove that permanent magnet is installed at spherical crown 201 internal surfaces; Also can be that permanent magnet is fixedly mounted between spool and spherical crown, at spool and spherical crown surface, respectively open a groove cooperatively interacting, permanent magnet is stuck in these two grooves.
Making its magnetic intensity that reaches spherical crown 201 surfaces is 10～50 Gausses' low-intensity magnetic field.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 problems such as foreign material absorption.
Make spherical crown 201 water around 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, protected the sphere non-scaling of spherical crown, be unlikely to again to affect the start-stop performance of valve.
Simultaneously; valve seat 203 is magnetized to processing; making the magnetic intensity after its magnetization is 10～50 Gausses; also can select weak magnetic (10～50 Gauss) Martensitic Stain Less Steel valve seat 203; make valve seat 203 water around be subject to low-intensity magnetic field impact, the incrustation scale of generation loses adsorptive power, has protected valve seat non-scaling; the magnetic of valve seat is very weak simultaneously, does not therefore also have foreign material absorption.
In all embodiments, spherical crown and valve seat form sealing pair below, and spool supports spherical crown and is connected with spherical crown.
