The air pressure use range of a product is 550-1020k Pa, the work voltage range DC (direct current) is 17.5-32V, the temperature use range rangs from -40 to 100 DEG C, the interference to a plurality of precision instruments and sensitive electronic components caused by the reversed electromotive force of a coil can be effectively reduced since the electromagnetic part is additionally provided with the piezoresistor, and the service life is 0.3 million times.
Description
Technical field
The utility model relates to the automobile electrical magnet valve, specifically is a kind of automobile normal open solenoid valve.
Background technique
At present the automobile electrical magnet valve of producing is generally Normally closed type, i.e. (no electric circuit) solenoid valve sealing gas circuit under the state usually, and the gas circuit of switching on is then opened, and the gas circuit of cutting off the power supply is then closed.But along with the continuous expansion of automobile function in fact, the solenoid valve that needs on some Special Category automobiles is a normal opened type, be that (no electric circuit) solenoid valve is connected gas circuit under the common state, the gas circuit of switching on is then closed, and the gas circuit of cutting off the power supply is then opened (working state is opposite with normally closed solenoid valve).Be mainly used in long-time ventilation, the control occasion that the short time domestic demand is died.
Summary of the invention
The purpose of this utility model is for realizing the short disconnected control function of normal open, proposing a kind of automobile normal open solenoid valve.
Technological scheme of the present utility model for this reason is, a kind of automobile normal open solenoid valve, comprise shell, valve seat, valve hole part, electromagnetic component, valve seat is provided with shell, it is characterized in that: described valve hole part is fixed on the valve seat by electromagnetic component, wherein be provided with armature assembly, be provided with ejector pin, spring and spool butt joint in the armature assembly on the top of spool; Wherein electromagnetic component presses by spacing core and receives in the shell, again and be welded with piezoresistance between the shell.
Improvement to such scheme is: described spool upper/lower terminal is provided with air cushion.
Improvement again to such scheme is: described electromagnetic component is that coil sub-unit, cover plate, O RunddichtringO are pressed into electromagnetic component, is injection molded into as a whole again.
Further improvement of these options is: described spacing core is made of brass.
Beneficial effect:
The utility model wherein electromagnetic component is earlier spacing core to be riveted on the shell, again and be welded with piezoresistance between the shell; After described ejector pin is loaded onto described spring, in the described armature assembly of packing into, in the described electromagnetic component of again it being packed into,, it is combined by the jam riveter riveted joint, then formed automobile normal open solenoid valve then with the described valve hole part described valve seat of packing into.In above-mentioned parts, armature assembly is in the effect activity of following time of electromagnetic force and spring.
The air cushion that the spool upper/lower terminal is provided with is in order to seal.
The raising of injection moulding all-in-one-piece electromagnetic component reliability.
Spacing core is brass bar, not magnetic conduction.

Embodiment
As shown in Figure 1 and Figure 2, this normal open solenoid valve, mainly constitute by valve seat 1, valve hole part 2, seal ring 3, ejector pin 4, spring 5, electromagnetic component 6, armature assembly 7, spacing core 19, dustproof seat 8, dust-proof cushion 9, dust cover 10, pack into 7 li of described armature assemblies of described ejector pin 4 the above spring 5 of cover, again it is packed into 6 li of described electromagnetic components, with pack into 1 li of described valve seat of described valve hole part 2, it is pressed on the valve seat 1 then by electromagnetic component 6.
As shown in Figure 3, described valve hole part 2 is to constitute at spool 12 and envelope air cushion 13;
As shown in Figure 4, described electromagnetic component 6 is 16 li on the shells of earlier spacing core 19 being pressed, again coil sub-unit 17, cover plate 14, O RunddichtringO 15 are pressed into assembly, weld piezoresistance 20 and plug sub-unit 21 again, by jam riveter plug sub-unit 21 and shell 16 are compressed, by injection moulding (nylon 66+30% glass) aforementioned component are integrated in together at last;
As shown in Figure 5, armature 22 and iron parts lower end surface rubber pad 23 in the armature assembly.
Working principle
Its principle as shown in Figure 6, under the no electric circuit situation, armature assembly is by spring and ejector pin jack-up, armature assembly upper-end surface rubber and spacing core envelope gas end are close to, relief opening 26 stuffiness, air-flow enters from suction port 24, by the valve hole part center hole, 25 discharge through the valve seat air outlet, and inlet hole 24 communicates with air outlet hole 25; After the energising, promptly 6.1 and 6.2 or 6.4 connect, spacing core 19 is a brass bar, magnetic conduction not, and armature assembly and valve hole part are the stainless iron staff of soft magnetism, magnetic conduction; Under the effect of coil magnetic field, armature assembly and valve hole part are magnetized, produce electromagnetic force simultaneously, because spacing core is magnetic conduction not, under the electromagnetic force effect, armature assembly overcomes spring force and moves downward, blocked by armature assembly lower end surface rubber until the valve hole part outlet side, air outlet 25 airless, closed electromagnetic valve, unnecessary pressurized gas are discharged by spacing core relief opening 26 in the valve pocket simultaneously; After the outage, armature assembly moves upward under the effect of spring force, resets, and blocks the relief opening 26 of spacing core, and the air outlet of valve hole part and valve seat air outlet are connected, and solenoid valve is opened, and inlet hole 24 is connected with air outlet hole 25.(ignoring armature assembly gravity and armature assembly kinetic friction force)
