Description
Technical field
The utility model relates to a kind of solenoid valve.
Background technique
The solenoid valve in gas technology field is a kind of more common automation foundation original paper, belongs to final controlling element, and application is wider, has mechanical control field that daily life field is also arranged.When using with the above-mentioned thermocouple of mentioning, solenoid valve is installed in the kitchen range air valve cavity in the use, plays the effect of switch; And the temperature receiving terminal of thermocouple contacts with gas flame, and the other end of thermocouple is connected with solenoid valve, when electric thermo-couple temperature receiving terminal temperature rises; Can produce electric current, pass to solenoid valve, the moving iron core in the solenoid valve is inhaled with static iron core mutually; The valve core of the electromagnetic valve retraction, the gas outlet of burner is unimpeded.When the gas cooker accident extinguishing and people have little time to close gas valve, even also unknown when flame-out, be easy to cause the accident of gas leakage, for this reason people through one with the cooperate blowout protection that carry out gas cooker of thermocouple with solenoid valve.
Solenoid valve comprises parts such as valve seat, valve bonnet, spring, valve shaft and sealing gasket, and said valve seat outer end is provided with electrode, is provided with moving iron core, static iron core in the described valve bonnet and is wrapped in the outer coil of static iron core skeleton.Present solenoid valve cooperates thermocouple to use, and the electric current that produces owing to thermocouple is very little, and the therefore general diameter that adopts is the blister copper silk winding of 0.53mm, to reduce resistance.Therefore this solenoid valve has certain requirement to the power supply unit that is mated, and the electric current that requires to be produced is less, can't be used with equipment such as dryelement cell.(because the voltage that thermocouple produces is very low, require its loop resistance little, therefore general employing diameter is the copper enameled cable coiling of 0.53mm, to reduce resistance.Because loop resistance is very little, so this solenoid valve has certain requirement to the power supply unit that is mated, and can't be used with equipment such as dryelement cell.) in addition, the electrode end surface of existing solenoid valve is plane when contacting with thermocouple, effectively area of contact is little, is prone to skid.
The model utility content
The technical problem that the utility model will solve is: provide a kind of can applied range, solenoid valve that the electrode end surface area of contact is big.
The technological scheme that the utility model is taked is: a kind of solenoid valve, and it comprises the valve seat that is set with valve bonnet, the other end of valve seat is provided with electrode; Be provided with the static iron core that connects valve seat in the valve bonnet; Twining coil on the skeleton outside the static iron core, also be provided with the moving iron core that is connected valve shaft one end in the valve bonnet, the other end of valve shaft connects a sealing gasket; Sealing gasket is positioned at outside the valve bonnet; Be provided with a spring and spring seat between sealing gasket and the valve bonnet end, spring housing is outside valve shaft, and forming the coil brass wire diameter is 0.05mm-0.09mm.
The curved indent in described electrode exterior edge face.
Be provided with insulating trip between described electrode and the valve seat.
The beneficial effect of the utility model is: it is the copper wire coiled of 0.05mm-0.09mm that the coil of the utility model adopts diameter, and ABAP Adapters such as suitable dryelement cell use together, is fit to wider.
As improvement, the curved inner concavity in described electrode exterior edge face, the area of contact of ABAP Adapters such as increase electrode and dryelement cell makes that the signal transmission is more accurate.
Description of drawings
The whole cross-sectional schematic of Fig. 1 the utility model.
Among the figure, 1, valve bonnet, 2, valve seat, 3, electrode, 3.1, the arc indent, 4, static iron core, 5, skeleton, 6, coil, 7, valve shaft, 8, moving iron core, 9, sealing gasket, 10, spring, 11, spring seat, 12, insulating trip.
Embodiment
Below be the utility model preferred embodiment, but therefore do not limit the protection domain of the utility model.
With reference to shown in Figure 1, a kind of solenoid valve of the utility model, it comprises the valve seat 2 that is set with valve bonnet 1; The other end of valve seat 2 is provided with electrode 3, is provided with the static iron core 4 that connects valve seat 2 in the valve bonnet 1, is twining coil 6 on the skeleton 5 outside the static iron core 4; Also be provided with the moving iron core 8 that is connected valve shaft 7 one ends in the valve bonnet 1; The other end of valve shaft 7 connects a sealing gasket 9, and sealing gasket 9 is positioned at outside the valve bonnet 1, is provided with a spring 10 and spring seat 11 between sealing gasket 9 and valve bonnet 1 end; Spring 10 is enclosed within outside the valve shaft 7, and forming coil 6 copper wires (copper enameled cable) diameter is 0.05mm-0.09mm.It is the coil 6 that 0.07mm processes that present embodiment adopts brass wire diameter.This novel on two shelfs of skeleton 5 respectively dextrorotation 200 circle copper wires (copper enameled cable) and left-handed 200 circle copper wires (copper enameled cable) formation coil.The resistance that the copper wire of this new design (coil) produces is bigger, can use external device connection uses such as dryelement cell.
In addition, as further improvement, the curved indent 3.1 in described electrode 3 exterior edge faces.Increase the area of contact of ABAP Adapters such as electrode 3 and dryelement cell, make that the signal transmission is more accurate.
Be provided with insulating trip 12 between described electrode 3 and the valve seat 2.Improve the safety of products performance.
The working principle of the solenoid valve in the middle of the working principle of the utility model and the existing technology is consistent, just no longer continues detailed narration here.
