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 the situation of power line at the electromagnet afterbody, if the position of power line changes, this will make troubles to the connection of power line, and increase very big 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 bigger, 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 that is used for air separation control device, this solenoid valve component good manufacturability, 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: this solenoid valve is a two-position three way normally closed switch valve, and 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 power effect of surging;
The structure of valve is formed: selector valve is by valve body, ball valve assembly, and armature component, coil block, spring, screw, packing ring, seal ring, component such as pad are formed, and 1. valve assembly adopts bivalve seat steel ball structure; 2. valve assembly and electromagnet demountable structure connect with screw between the two; 3. the pole shoe member both ends of the surface are two locatees; 4. go between and pass, draw from end opposite from valve body; 5. solenoid valve is the flange-type mounting structure.
Compared with the prior art, the present invention is in this electromagnetic valve structure, valve assembly adopts bivalve seat steel ball structure, this structure can be well spacing to steel ball, and the flow of switch valve comes control flow rate 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, has also improved the conformity of solenoid valve flow, and this structure has had very big 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, help producing 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.Make every performance index energy proper functioning of solenoid valve.
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 for use of the mounting type of solenoid valve, the different installation of mounting interface is just different, and the layout of mounting interface will directly influence machine performance output and size, weight.Therefore, this installation and design again the using scope of having widened solenoid valve again.
