Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail, described in be to this utility model
Explanation rather than restriction.
As in figure 2 it is shown, this utility model includes electric pushrod 1, push rod installing plate 2, central layer and valve body
6, central layer includes central layer main body 3, seal washer 4 and yoke 5；In central layer main body 3, yoke is installed
5, act primarily as the effect of conducting magnetic circuit, seal washer 4 plays sealing between central layer main body 3 and yoke 5
Effect.Central layer inserts in valve body 6, and push rod installing plate 2 is arranged on valve body 6, and electric pushrod 1 slides
It is arranged on push rod installing plate 2, and electric pushrod 1 is fixed with central layer and is connected.As shown in Figures 3 and 4,
Central layer main body 3 includes fixing magnetic system 9 and mobile magnetic system 10, and mobile magnetic system 10 is connected to by spring 11
Fixing magnetic system 9 middle part.It is fixed on the fixing magnetic system 9 of central layer main body 3 one end by multiple parallel and phase
Mutual spaced magnetic group forms, and includes multiple permanent magnets in each magnetic group, and permanent magnets depends on along pole orientation
Secondary layout, the magnetic pole of adjacent permanent magnet block is contrary；Mobile magnetic system 10 is slidably arranged in the another of central layer main body 3
One end, the magnetic group structure of mobile magnetic system 10 is identical with the magnetic group structure of fixing magnetic system 9, mobile magnetic system 10
Magnetic group be embedded between the magnetic group of fixing magnetic system 9.Wherein, move in magnetic system 10 and be provided with limiting block
Block 12；When valve body 6 is opened, spring 11 promotes mobile magnetic system 10 to left movement, positive stop 12
Just stagger the length of a permanent magnets in the position of the position and fixing magnetic system 9 that limit mobile magnetic system 10；
When valve body 6 is closed, mobile magnetic system 10, by the counteracting force of body base, makes the shifting of mobile magnetic system 10
Dynamic, positive stop 12 limits the position of mobile magnetic system 10 and just aligns with the position of fixing magnetic system 9.
In this preferred embodiment, as shown in Figure 3 and Figure 4, mobile magnetic system 10 includes two groups of magnetic groups, fixing
Magnetic system 9 includes that three groups of magnetic groups, two groups of magnetic groups of mobile magnetic system 10 are respectively embedded in the three of fixing magnetic system 9
In two intervals that group magnetic group is formed.Each magnetic group all includes five permanent magnets.
During use, this device is arranged on vertical direction slurry at disc mill stock inlet by mounting flange 7
Immediately below pipeline 8, under disc mill normal operating conditions, slurry is flowed to horizontal pipe by vertical pipeline and goes forward side by side
Entering disc mill stock inlet, now, this device valve port is closed, now, and the central layer in valve body 6
Band is magnetic, when the irony foreign material in slurry can be flowed through this device by vertical pipeline, due in device
The magneticaction of magnetic central layer, absorption yoke 5 surface on central layer, stop irony foreign material entrance dish
Grinding machine.When equipment downtime maintaining, valve port can be promoted automatically to be beaten by this device by electric pushrod 1
Opening, now central layer does not the most have magnetic, it is impossible to continue to attract to be fixed on yoke 5 surface by irony magazine,
The absorption irony foreign material on yoke 5 surface are automatically drained out.
Operation principle of the present utility model is under device opening, as it is shown on figure 3, mobile magnetic system 10
Ejecting under the effect of spring 11, movement magnetic system 10 is limited to appointment position by positive stop 12, makes
Just staggering the length of a permanent magnets in the position of the position and fixing magnetic system 9 that must move magnetic system 10, makes
Aliging with the S pole of fixing magnetic system 9 in the N pole of mobile magnetic system 10, the S pole of mobile magnetic system 10 is with fixing
The N pole alignment of magnetic system 9, according to the principle of continuity of magnetic flux and magnetic field superposition principle, magnetic pole cancellation, magnetic
Property reduce, core plate surface, substantially without producing magnetic, does not produce magnetic in actual application.Such as Fig. 4 institute
Show.When the device is closed, electric pushrod 1 promotes central layer to move, and mobile magnetic pole 10 touches valve body 6
Bottom time, under the thrust of electric pushrod 1, mobile magnetic system 10 gradually moves right, spacing
Movement magnetic system 10 is limited to specify position by block 12, makes the position of mobile magnetic system 10 and fixing magnetic system
The aligned in position of 9, it may be assumed that aliging in just N pole with fixing magnetic system 9, the N pole of mobile magnetic system 10, moves
Aliging with the S pole of fixing magnetic system 9 in the S pole of dynamic magnetic system 10, folds according to the principle of continuity of magnetic flux and magnetic field
Adding principle, now magnetic field superposition, the magnetic line of force from magnet N pole out, through yoke 5, returns to magnet
S pole, yoke surfaces produces magnetic such that it is able to by irony impurity absorption in yoke surfaces.
