In the structure of regular tap solenoid valve, the pole shoe major part all is a direction location, will cause like this relative position requirement of armature and armature pipe, increased the friction of armature, shortened the working life of valve, in case the position of pole shoe changes simultaneously, the magnetic energy ring will be affected, thereby affect the fluctuation of electromagnetic force, the property indices of solenoid valve can not normally be finished.
In the structure of regular tap solenoid valve, the lead-in wire of coil all is to draw from the electromagnet afterbody, and this makes things convenient for power line in the situation of electromagnet afterbody, if the position of power line changes, this will make troubles to the connection of power line, and increase very large difficulty for the design of circuit.
In the structure of regular tap solenoid valve, press mounting type, it can be divided into the formula of inserting and two kinds of mounting types of flange plate, the different installation of mounting interface is just different.With regard to its cartridge valve, higher to the size requirement of plug-in mounting part, processing difficulties, the length dimension of general required installation is larger, and the scope of use is relatively just narrower.
Summary of the invention: the object of the present invention is to provide a kind of solenoid valve for air separation control device, this solenoid valve component technological is good, and assembling is simple, and stain resistance is strong, is convenient to clean, and can reach the purpose of reliable operation, simple in structure and long service life.
Formation of the present invention: formed by component such as valve body, ball valve assembly, armature component, coil block, spring, screw, packing ring, seal ring and pads;
Its assembled relation is: coil is enclosed within is pressed into coil housing on the pole shoe member again, just formed coil block, steel ball is put into valve seat, after mixing up stroke, load onto pad, again ball valve assembly is pressed into valve body, the spring of packing into, armature component and seal ring, then link together with screw, packing ring, just consisted of solenoid valve.
Solenoid valve of the present invention is two-position three way normally closed switch valve.During no electric circuit, the elastic force that spring produces is pushed steel ball and armature component to the right side, and steel ball seals up filler opening, and fluid flows to return opening from the control mouth; During energising, electromagnetic force sucts armature component, and with the return opening sealing, at this moment, fluid flows to the control mouth from filler opening to steel ball under the hydraulic power effect.
In this electromagnetic valve structure, adopt valve assembly to adopt the double-valve-seat steel ball structure, this structure can be well to steel-ball limiting, and the flow of switch valve is controlled flow by stroke, in assembly process, directly the gap of valve base chamber is controlled the stroke of steel ball, this just brings convenience to assembling and setting, also improved the conformity of solenoid valve flow, this structure has had very large improvement to the processing technology of valve body and valve seat simultaneously.
In the structure of this solenoid valve, electromagnet and valve body partly are to dismantle, and assembling and setting just is easier to, and this has also brought convenience to proposition cleaning, replacing and the maintenance of component.Improved greatly solenoid valve working life, reduced cost of production, be conducive to produce in enormous quantities.
In the structure of this solenoid valve, what pole shoe adopted is two-way location, shortens the working life of solenoid valve and the fluctuation of magnetic valve performance with regard to avoiding position because of pole shoe to change like this.The property indices of solenoid valve can be worked.
In the structure of this solenoid valve, the lead-in wire of coil is to pass valve body to draw from the attachment face of valve body, and this makes things convenient for the connection of power line, the multiple choices scheme is provided for the layout of power line, has simplified the layout of electric wire and has widened the using scope of solenoid valve.
In the structure of this solenoid valve, mounting type is the flange plate mounting type, and disc type is installed and is applicable to filler opening, control mouth, return opening in conplane situation, and the relative plug-in type of his processing requires lower, and technology capability is better.On aircraft, be subjected to the restriction of space and weight, quite crucial to selecting of the mounting type of solenoid valve, the different installation of mounting interface is just different, and the layout of mounting interface will directly affect the performance output of complete machine and size, weight.Therefore, this mounting design again the using scope of having widened solenoid valve again.
