Abstract

The utility model discloses a low noise electromagnetic valve. The electromagnetic valve comprises a coil component, wherein an inner sleeve is arranged inside the coil component; a magnetic conducting core, a spring and an iron core which are matched with one another are arranged in the inner sleeve form the upper part to the lower part in sequence; the electromagnetic valve is characterized in that the magnetic conducting core is fixedly arranged in the inner sleeve; a limiting platform is integrally arranged on the inner sleeve; the spring is pressed between the limiting platform and the iron core; the limiting platform is used for separating the magnetic conducting core from the iron core. The electromagnetic valve has the advantages that the operation noise of a water inlet electromagnetic valve applied on a domestic appliance is greatly reduced on the premise that all performances of the electromagnetic valve are not weakened, the matching structure is also optimized, the production process is simplified, and the product quality is enhanced.

Description

A kind of low noise solenoid valve
Technical field
The utility model relates to a kind of solenoid valve, especially relates to a kind of low noise solenoid valve.
Background technique
The entering water electromagnetic valve using on existing most of household electric appliance, the noise when rated power is worked is generally larger, is generally all greater than 35dB, cannot meet the occasion that some have higher requirements to inlet valve noise.Although exist minority for the so-called low noise solenoid valve of household electric appliance on market, but its unreasonable structure, although the noise in the time of can reducing electromagnetic valve work, but can have a strong impact on other important performances of solenoid valve, startability and the water sealing property of solenoid valve have been weakened, the possibility that exists solenoid valve to lose efficacy.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of assurance and, under the not weakened prerequisite of solenoid valve properties, effectively reduces the low noise solenoid valve of operating noise, its reliable in structure, function admirable.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of low noise solenoid valve, comprise coil block, the inside of described coil block is provided with inner sleeve, in described inner sleeve, be disposed with from top to bottom suitable magnetic conduction core, spring and iron core, described magnetic conduction core is fixedly installed in described inner sleeve, in described, put and be wholely set limited location platform, between limit dais described in described spring is pressed in and described iron core, described limit dais is kept apart described magnetic conduction core and described iron core.
Described inner sleeve is by Shooting Technique moulding, described magnetic conduction core is fixedly installed in described inner sleeve by Shooting Technique, in described inner sleeve, be provided with annular stop groove, the outer surface of described magnetic conduction core is provided with the annular protrusion suitable with described annular stop groove, optimized cooperating structure, simplify production process, improved the reliability of solenoid valve.
The height of described limit dais is 0.1mm-0.3mm, has guaranteed the normal operation of solenoid valve.
Compared with prior art, the utility model has the advantage of because magnetic conduction core is fixedly installed in described inner sleeve, inside put and be wholely set limited location platform, spring is pressed between limit dais and iron core, limit dais is kept apart magnetic conduction core and iron core, when electromagnetic valve work, iron core is drawn to precalculated position, the now upper surface of iron core and limit dais laminating, iron core is in relative static conditions, spring is between limit dais and iron core, spring by compression after the also relative static conditions in stress balance, so just substantially eliminated because of vibration, the noise that collides and produce, now only there is extremely slight electromagnetic sound, when solenoid valve quits work, the magnetic field that coil block produces disappears, but magnetic conduction core is partially or completely magnetized, be equivalent to a small magnet, because the existence of limited location platform, the attraction force that now iron core is subject to magnetic conduction core has been reduced many, be far smaller than the pulling force sum producing after deboost that compression deformation of the spring produces and seal ring deformation, iron core moves downward specified position, rubber core lower surface is adjacent to seal ring frame mesopore, thereby make solenoid valve stop water outlet and keep good water sealing property, prevent that leaking from appearring in solenoid valve, guaranteeing under the not weakened prerequisite of solenoid valve properties, greatly the reduction of degree noise during the work of the entering water electromagnetic valve that uses on household electric appliance, can meet the occasion partly inlet valve noise being had higher requirements completely, optimize cooperating structure simultaneously, simplified production process, promoted quality of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing at A place in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
Embodiment one: as shown in the figure, a kind of low noise solenoid valve, comprise coil block 1, the inside of coil block 1 is provided with inner sleeve 2, in inner sleeve 2, be disposed with from top to bottom suitable magnetic conduction core 3, spring 4 and iron core 5, inner sleeve 2 is by Shooting Technique moulding, magnetic conduction core 3 is fixedly installed in inner sleeve 2 by Shooting Technique, in inner sleeve 2, be provided with annular stop groove 21, the outer surface of magnetic conduction core 3 is provided with the annular protrusion 31 suitable with annular stop groove 21, in inner sleeve 2, be wholely set limited location platform 22, spring 4 is pressed between limit dais 22 and iron core 5, limit dais 22 is kept apart magnetic conduction core 3 and iron core 5, the height L of limit dais 22 is 0.2mm.
Embodiment two: other parts are identical with embodiment one, and its difference is: the height L of limit dais 22 is 0.1mm.
Embodiment three: other parts are identical with embodiment one, and its difference is: the height L of limit dais 22 is 0.3mm.
