Description
Technical field
The utility model relates to a kind of medium circulation control apparatus, relates in particular to a kind of high-frequency electromagnetic valve with sorting apparatus Control work medium break-make.
Background technique
Solenoid valve is to utilize electromagnetic effect to realize the industry equipment of control function, a kind of for valve, and its working principle is the electromagnetic force that produces through control electromagnetic coil energising back, realizes the unlatching of solenoid valve or closes, mobile with this control flows body medium.According to the difference of valve core structure form, solenoid valve can be divided into types such as slide column type, seat valve formula, traveller seat valve formula and slide board type.
Color selector is to be used for the defective products of materials such as rice is rejected, and can carry out the Hi-Tech equipment of classification to material.Compare with traditional sorting apparatus, color selector has outstanding advantages such as precision of color separation height, reliable in quality, feature richness.And the core component of carrying out as color selector sorting action, solenoid valve adopts the seat valve formula more.This be because; Seat valve formula solenoid valve has " not needing oil mist lubrication; avoided the pollution to sorted materials such as rice ", " the very little amount of movement of usefulness just can make the spool complete opening or close; satisfied color selector to the short requirement of spray response valve time " and advantages such as " good sealing effect have improved and taken ratio out of ".Take out of than being meant, under the normal condition, after the spray valve is rejected operation to the defective products particle; Tail gas can exert an influence to the non-defective unit particle of follow-up whereabouts; Carry it in the disallowable defective products material, and in the disallowable material, the defective products particle is with the non-defective unit proportion of particles and takes ratio out of.Take out of than the important performance indexes that is color selector, when other conditions equate, take out of highlyer than more, to reject ratio just low more for the mistake of non-defective unit particle in the sorted materials, and the performance of color selector is good more.
The straight-through seat valve formula solenoid valve that existing color selector generally adopts mainly is made up of valve tail, valve seat, moving plate, iron core sleeve, iron core and coil.Valve tail, valve seat, moving plate and iron core sleeve are connected in order, and iron core is arranged in the iron core sleeve, and are provided with coil between iron core and the iron core sleeve, and the afterbody of iron core and iron core sleeve directly contacts moving plate.Valve tail communicated cavity Cross section Design becomes rectangle, and the degree of depth of valve tail communicated cavity is bigger.That this solenoid valve has is simple in structure, processing and advantage such as easy to assembly.But, several kinds of shortcomings below existing straight-through seat valve formula solenoid valve exists:
The first, tail gas is big, and for the color selector that uses this spray valve, it takes than is difficult to further raising out of.This be because, carrying out solenoid valve when design, for easy to process; Valve tail communicated cavity cross section is designed to rectangle, and simultaneously in order to reduce the suffered resistance of air-flow, the degree of depth of valve tail communicated cavity is bigger; This has just caused the volume of valve tail communicated cavity bigger, after carrying out the defective products rejecting, though the spray valve cuts out; But residual more pressurized gas in the valve tail communicated cavity, these residual pressurized gas form tail gas when carrying out puffing.Particularly when carrying out small particles material sorting such as small Semen setariae, these tail gas are just more serious to the harmful effect of taking out of than causing.Take out of lowlyer than more, the non-defective unit particle that contains in the disallowable material is just many more, and this has just caused serious wastage of material.For avoiding wastage of material, existing technology is that disallowable material is carried out the secondary sorting, so that the non-defective unit particle in the disallowable material is reclaimed, still, this has caused the increase of energy consumption and the reduction of manufacturing efficiency again.
The second, shortcoming such as have that noise is big, the life-span is short, this is because when solenoid valve is opened with closing motion, moving plate directly and iron core sleeve and iron core collide, cause the generation of noise and wearing and tearing.Particularly along with the development of color selector technology, the switching frequency of spray valve is increasingly high, and the movement velocity of moving plate also increases thereupon, and the noise of generation is also serious further with wearing and tearing.
The 3rd, this solenoid valve is invaded by particulates such as dust in storage and transport process easily, can not effectively close when causing solenoid valve work.This is because this solenoid valve relies on pressurized gas that moving plate is pressed on the valve seat in the course of the work, to close solenoid valve, still; In processes such as accumulating, can't remain under valve tail one side direction, moving plate also just can not keep combining closely with valve seat; At this moment, particulates such as dust can be invaded solenoid valve inside, between moving plate and valve seat, pile up; When causing solenoid valve work, moving plate can not closely contact with valve seat, thereby causes gas leakage.
The model utility content
For solving the problem that existing straight-through seat valve formula solenoid valve exists; The utility model provides a kind of novel high-frequency solenoid valve, and its noise is lower, the life-span is longer, and uses the color selector of this solenoid valve; Can significantly improve and take ratio out of, improve raw material availability, reduce energy consumption, enhance productivity.
