Abstract
The utility model relates to an electromagnetic valve, which is composed of a magnet conducting casing 1, a coil 2, a mandrel 5 and a return spring 8, wherein, the inner side of the coil 2 is provided with a magnet isolating sleeve 4; the mandrel 5 can move along the axis direction in the magnet isolating sleeve 4; the inner side of the dead end of the magnet conducting casing 1 is provided with a dummy club 9; a magnet 10 is embedded in the mandrel to realize bidirectional driving. The suction force along an axial direction to the mandrel is greatly enhanced and reliable operation can be realized under the high temperature condition of 90 DEG C.
Description
The utility model belongs to the calutron technical field, relates in particular to a kind of novel solenoid valve.
No matter be at mechanical field or at electric field, solenoid valve often is used to control the operating position of some devices.In prior art, solenoid valve all is to adopt electromagnetic coil, action element and return spring structure.Because leakage field on the structure, these solenoid valve ubiquity power are little, volume big, the insecure problem of action under the temperature condition with higher.In addition, the prior art solenoid valve all is a unidirectional drive, and its action element need lean on the spring return, if the elastic force of spring is improper.Insecure phenomenon also can appear moving.
The purpose of this utility model will overcome the deficiency of above-mentioned prior art exactly, and a kind of power is big, volume is little, the electromagnetic valve of high temperature resistant bi-directional drive but provide.
The purpose of this utility model is achieved in that a kind of solenoid valve, form by magnetic conduction casing, coil, mandrel and return spring, it is characterized in that the coil inboard is provided with every the magnetic core cover, mandrel can move along axial direction in the magnetic core cover, the perforate end of housing is provided with every the magnetic steering cover, and the cecum inboard is provided with boss.
In order to realize bi-directional drive, can in such scheme, cancel return spring, and be embedded in magnetic patch at mandrel.
In order to realize the purpose of this utility model better, described boss stretches in the magnetic core trepanning.
Adopt scheme of the present utility model, the magnetic field that electromagnetic coil produces along housing guiding cecum, again through boss guiding mandrel, thereby is concentrated the magnetic line of force by after the magnetic core cover separates, and has strengthened the axial suction to mandrel significantly.Owing to be embedded in magnetic patch at mandrel,, can realize the bi-directional drive of mandrel as long as change the energising polarity of coil.The experiment proved that, solenoid valve of the present utility model can be under 90 ℃ high temperature action message.
Fig. 1 is embodiment's schematic diagram of the utility model unidirectional drive solenoid valve.
Fig. 2 is embodiment's schematic diagram of the utility model bi-directional drive solenoid valve.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Referring to Fig. 1, unidirectional drive solenoid valve housing 1 adopts permeability magnetic material, and electromagnetic coil 2 is positioned at housing 1 inside, and two terminal 3 of coil 2 are drawn from housing 1.Be provided with every magnetic core cover 4 in the inboard of electromagnetic coil 2, its material can be selected NULL such as copper or 1Cr18Ni9Ti steel for use.Mandrel 5 usefulness soft magnetic materials are made, and part places in magnetic core cover 4, and part is stretched out the outside from housing 1 one STH ends, can move along axial direction.Between the outer end of mandrel defining flange 6 and housing, be provided with return spring 8.Making of opening in shell end every magnetic steering cover 7 employing H62 copper products.There is a boss 9 the cecum inboard of housing, stretches in the hole of core retainer plate 4.After connecting power supply, electromagnetic coil 2 generation magnetic fields, owing to the effect every magnetic core cover 4 and magnetic conduction casing 1 and boss 9 thereof, the magnetic line of force is concentrated the axial direction of guide ledges 9, thereby mandrel 5 is attracted the displacement action of realization mandrel 5.After the outage, magnetic field disappears, under the effect of return spring 8, and mandrel 5 return-to-home positions.
If will realize bi-directional drive, then cancel return spring, mandrel 5 adopts for example such NULL of 1Cr18Ni9Ti, is embedded in magnetic king's and so on magnetic patch 10 at mandrel.When switching on a kind of polarity, magnetic field attracts mandrel 5 to a direction, realizes displacement; When switching on opposite polarity, magnetic field attracts mandrel 5 round about, realizes displacement.See Fig. 2.
