Description
Technical field
The utility model relates to a kind of electromagnetic valve structure.
Background technique
Own now maintenance solenoid valve is just announced shown in No. 557462 as TaiWan, China, and it comprises: single coil, and it is twining a bobbin in a direction; One removable iron stamen, itself and a fixed iron stamen are configuration coaxially; First spring, it promotes this removable iron stamen away from this fixed iron stamen; And an annular permanent magnnet, its end points that is mounted to the end points of this fixed iron stamen and this removable iron stamen is part toward each other.This annular permanent magnnet part is round the external peripheral surface of this fixed iron stamen and this removable iron stamen.
Under this coil state of not powering, the elastic force fs of spring is greater than the attraction force F of this permanent magnet, but so that removable iron stamen involution initial point.
Supplying power under this coil state, promptly producing this solenoidal attraction force, in order to adding to the attraction force of this permanent magnet, and producing this strength, this strength is greater than the elastic force of this spring, so that this solenoid valve can be in the unlatching ON state.
After being in this unlatching ON state, this solenoid valve make electric power end to supply power to this coil, this permanent magnet is bestowed fixed iron stamen magnetic and is connected the elastic force of the greatest attraction forces of removable iron stamen greater than this spring, keeps the function of strength so that can reach to control oneself under need not electric power.
Continue it, after this electric power is ended to supply power to this coil, if the power supply with reversing current polarity is to this coil, then the elastic force of this spring is greater than a strength, this strength deducts this solenoidal attraction force by the attraction force of this permanent magnet and is produced, and so can make removable iron stamen involution initial point.
Make a general survey of this structure, it at least still has following three shortcomings:
One, overall structure and be unfavorable for accurate assembling; Because being group, fixed iron stamen is fixed in bobbin, removable iron stamen then is to sleeve to formed track between guide ring and permanent magnet, these tracks that close for removable iron stamen cunning are made of single component, so making and must pay special attention to during assembling guide ring and the caused interference of the permanent magnet cumulative limit situation that has some setbacks, especially permanent magnet quite is unfavorable for precision cutting processing, causes the control of whole manufacture cost and precision real in being difficult for.
Two, still have the space of improving of power saving; Its fixed iron stamen, the attraction force of removable iron stamen end points when being connected with each other are quite big, so removable iron stamen is desired by involution initial point under the hold mode, coil must be enough to make removable iron stamen end points to break away from fixed iron stamen end points with sizable reversing current polarity supplier of electricity, these electric currents are quite big and waste, and it really has necessity of minimizing.
Three, still have working life to be strengthened; Its removable iron stamen is excitatory down in coil moment, its removable iron stamen end points can powerfully collide fixed iron stamen end points, the permanent use down, vibrations that this collision causes can cause removable iron stamen that the error situation that the position is loosening or slippage has some setbacks is arranged, make this solenoid valve can't reach accurate automatic control function, and must change again.
Because the structural design of existing own maintenance solenoid valve causes the precision machining cost to increase, and working life long shortcoming, be professional experiences and the gains in depth of comprehension with for many years, grind through constantly conceiving, creating, be to develop the utility model.
