Abstract
The utility model comprises a valve body, a valve base equipped in the valve body, a control element cooperated with the valve base and a drive device connected with the control element. A magnet retainer is equipped on the inner wall of the valve body; a permanent magnet is equipped on the magnet retainer. The permanent magnet carries out magnetization processing for the agent flowing across the valve body, so that the impurity contained by the working agent closes to the center of the duct under the function of the magnetic field, and it prevents the impurity assembling at the sealing surface to increase the grind to the surface, and raises the service life of the valve. In addition, when the valve is used for the water supply duct, it can provide magnetized water for living and is beneficial to human body health.
Description
Technical field
The utility model relates to a kind of valve, relates generally to a kind of medium to the valve of flowing through and magnetizes the valve of processing.
Background technique
Traditional valve is after long-term the use, and the impurity in working medium knot easily forms fouling on the surface of sealing surface, causes the wearing and tearing of sealing surface, has influenced the working life of valve.
Summary of the invention
Thereby the purpose of this utility model provides a kind of impurity of flowing through in the valve that can prevent improves the valve valve in working life in the sealing surface fouling.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: this Magnetic valves comprises valve body, be arranged on valve seat in the valve body, with valve seat control unit that matches and the drive unit that is connected with control unit, the inwall of valve body is provided with magnetizing assembly.
Described magnetizing assembly comprises magnet retainer and permanent magnet, and the magnet retainer is circular, and its cylindrical matches with valve interior wall, is symmetrically arranged with at least two shrinkage pools on the cylindrical of magnet, and permanent magnet is contained in the shrinkage pool, and the bottom of shrinkage pool is provided with small through hole.
Valve interior wall is provided with groove, and the magnet retainer is split at least two sections, is embedded in the groove.
The magnet retainer by screw on valve body.
Described permanent magnet is columniform.
The magnet retainer is arranged on the side of valve seat.
Owing in valve body, be provided with magnetizing assembly, permanent magnet in the magnetizing assembly has carried out magnetization to the medium of flowing through to be handled, the impurity that working medium is included is drawn close to pipeline center under the effect in magnetic field, prevent the wearing and tearing that impurity is assembled to be increased in sealing surface its surface, the working life of having improved valve.In addition, when this valve is used for water supply pipe, also can provide, be of value to health through magnetized domestic water.

Embodiment
Present embodiment is a kind of magnetic force butterfly valve (see figure 1), comprises valve body 1 and is contained in valve shaft 6 in the valve body, and the overhanging end of valve shaft 6 is connected with the output terminal of unit head 9, and unit head 9 is manual, also can adopt in addition surge, electronic or pneumatic.Butterfly plate 5 is housed on valve shaft 6, and the valve seat in butterfly plate 5 and the valve body 1 matches, and is fixed with seal ring 2 and pad 3 in the cooperation place by trim ring 4.The inwall of valve body 1 is provided with magnet retainer 7, and permanent magnet 8 is housed on the magnet retainer 7.Magnet retainer 7 is circular, its cylindrical matches with the inwall of valve body 1, is symmetrically arranged with at least two shrinkage pools on the cylindrical of magnet retainer 7, and permanent magnet 8 is contained in the shrinkage pool, the bottom of shrinkage pool is provided with small through hole, and small through hole helps the (see figure 2) of passing through of the magnetic line of force.In the present embodiment, symmetry has been installed 20 permanent magnets 8 on the magnet retainer 7, and permanent magnet 8 is columniform.In addition, the quantity of permanent magnet can be two or more symmetrically arranged any numbers, and permanent magnet 8 also can be other arbitrary shape, as long as match with shrinkage pool on the magnet retainer 7.In the present embodiment, the inwall of valve body 1 is provided with ring groove, and magnet retainer 7 is split at least two sections, is embedded in the groove.In addition, magnet retainer 7 also can be by screw on valve body 1, or directly magnet retainer 7 is welded on the valve body 1; Except structure shown in Figure 2, the magnet retainer can also be netted, maybe permanent magnet can be fixed and can be made other shape that the magnetic line of force passes through.
For fear of the sealing surface fouling, should magnet retainer 7 be arranged on as far as possible valve seat near, in the present embodiment, magnet retainer 7 is arranged on a side of valve seat.
Except butterfly valve, this magnetizing assembly can also be used for preventing the various valves of the impurity of working medium in the sealing surface fouling, valve as other types such as ball valve, gate valves, the position that only needs the magnet retainer to be installed in the close sealing surface of valve interior wall gets final product, and the magnet retainer can be contained on the valve interior wall by the mode of embedding, screw or welding.
Figure 5 shows that a kind of magnetic force gate valve, be provided with seal ring 10 between the valve seat in flashboard 5 and valve body 1, magnet retainer 7 is housed on the inwall of valve body 1, permanent magnet 8 is housed in magnet retainer 7, handwheel 9 drives valve shaft 6 rotations and makes flashboard 5 liftings, for opening, for closing, this magnetic force gate valve is equipped with magnetizing assembly respectively on the inwall of the valve body 1 of flashboard both sides during decline during rising.
This structure also is applicable to need be with the magnetized various valves of working medium, when this valve is used for water supply pipe, can provide through magnetized domestic water, are of value to health.
