This solenoid valve also includes magnetic isolating pad, and described magnetic isolating pad is located between spool and the magnetic support.
This solenoid valve also includes spacer, and described spacer is located between valve body and the spool.
The advantage that the utlity model has: simple in structure, reliable, the easily processing of sealing; Adopt the full-metallic component, very strong corrosion resistance is arranged, can be applicable to the Flow-rate adjustment of all gases.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a perspective exploded view of the present utility model;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the partial enlarged drawing of Fig. 2.
Embodiment:
A kind of solenoid valve shown in Fig. 1,2 and 3, this solenoid valve include valve bonnet 2, coil 3, seat 4, valve body 5, packing ring 9, spacer 10, spool 7, magnetic isolating pad 11, magnetic support 12 and valve port 13; Described coil 3, seat 4 and valve body 5 are located in the valve bonnet 2, and described valve body 5 is empty hood-like; Described spool 7, packing ring 9, spacer 10, magnetic isolating pad 11, magnetic support 12 and valve port 13 are located in the valve body successively; Described valve port 13 is provided with two through holes, and described magnetic support 12 central authorities are provided with tubaeform through hole, and described two through holes and tubaeform through hole form the fluid passage; Be welded with guiding reed 6 and reed 8 on the described spool 7, magnetic support 12 tubaeform through holes are passed in its lower end, can be located at the through hole top of valve port 13 up or down.Magnetic isolating pad 11 is located between spool 7 and the magnetic support 12; Spacer 10 is located between valve body and the spool 7.
Valve bonnet 2, seat 4, valve body 5, packing ring 9, spacer 10, spool 7, magnetic isolating pad 11, magnetic support 12 and valve port 13 all are that metallic material is made.Wherein, valve bonnet 2, spool 7 and magnetic support 12 all are that permeability magnetic material is made.
Above-mentioned solenoid valve is fixedly connected on the fluid line 16, and import and outlet are arranged on the fluid line 16, is communicated with two through holes of valve port 13 respectively.Big metallic gasket 15 and little metallic gasket 14 are installed between solenoid valve and the fluid line 16, solenoid valve are fixedlyed connected with fluid line 16 by clamping bolt 1.Wherein, valve body closely contacts with big metallic gasket 15, guarantees that the fluid passage that two through holes and tubaeform through hole form is a sealing configuration.
Working principle: when outage, spool 7 is still in a certain position in the valve body, and with valve port 13 certain distance is arranged, and at this moment, flow is maximum.After giving coil 3 energisings, regulate input voltage value, the suction of 12 pairs of spools 7 of magnetic support changes along with the variation of input voltage value.Therefore, the position of spool 7 in valve body 5 changes along with the variation of input voltage value, and distance changes between spool 7 and the valve port 13 thereby make, and realizes adjusting the size of flow.When input voltage value increases to a certain value, make between spool 7 and the valve port 13 that distance is zero, the flow of this moment just is zero, this moment, this solenoid valve was realized the function of closing.
The effect of each part:
The effect of clamping bolt 1 is that solenoid valve and fluid line 16 are tightened retaining element; Valve bonnet 2 is to be made by permeability magnetic material, and its effect is contained in its inside with all component; Reduce the loss of the magnetic line of force.Coil 3 effects are that energising produces magnetic field.Seat 4 effects are to bear pressure, and clamping bolt 1 is tightened, and valve bonnet 2 is to down pressing seat 4, and seat 4 is to pressing down valve body 5.There is circular hole at the center of seat 4, and protection valve body 5 is not damaged by pressure.Valve body 5 is a permeability magnetic material.Valve body act as:
1, valve body, big metal o-ring 15 and fluid line 16 form the space of sealing, and gas can not leak outside.
2, the permeability magnetic material of valve body can reduce the loss of the magnetic line of force effectively.
Be welded with guiding reed 6 and reed 8 on the spool 7, spool 7 is a permeability magnetic material, can move up and down under the effect of electromagnetic force.Guiding reed 6 can guarantee that spool does the motion of straight line.
The quantity of increase and decrease spacer 10, the scope that regulating spool 7 moves up and down.
Magnetic isolating pad 11 prevents that spool 7 from contacting with magnetic support 12, causes magnetic line of force short circuit.
12 pairs of spools of magnetic support 7 produce downward suction.
Valve port 13 is regulated the size of flow with spool 7.
