Description
Technical field
The present invention relates to Solenoid Valve Technology field, relate in particular to a kind of switch electromagnetic valve.
Background technique
Switch electromagnetic valve is the industrial part by Electromagnetic Control, is the automation foundation element for controlling fluid, belongs to final controlling element, is used in direction, flow, speed and other the parameter of in industrial control system, adjusting medium.In switch electromagnetic valve, be typically provided with airtight chamber, and have through hole at diverse location, each through hole connects different tracheaes, carrys out the movement of control valve body by obtaining dead electricity, thereby opens or close different through holes.In prior art, switch electromagnetic valve exists the response time long, and the defect that return is slow need to be improved.
Summary of the invention
In order to solve the technical problem existing in background technique, the present invention proposes a kind of switch electromagnetic valve, realize the improvement to switch electromagnetic valve, make the switch electromagnetic valve response time short, return is fast.
A kind of switch electromagnetic valve that the present invention proposes, comprise valve body, in valve body, be provided with static iron core, moving iron core, coil, static iron core, moving iron core is all arranged in valve body, moving iron core is positioned at static iron core top, on the end face of moving iron core near static iron core, be provided with inner chamber, in above-mentioned inner chamber, be provided with the first spring, above-mentioned first spring one end is connected with static iron core and the other end is connected with moving iron core, on the end face of moving iron core away from static iron core, be provided with strut, it is stifled that strut is provided with valve away from moving iron core one end, the stifled side of valve contacts with valve interior wall by lining, lining and valve interior wall part are provided with seal ring, valve is stifled is provided with cavity away from described strut one side, in above-mentioned cavity, be provided with the second spring, second spring one end and valve be stifled to be connected and the other end is connected with valve body, on valve body, be provided with inlet hole and air outlet hole by the stifled positioning control break-make of valve, the elasticity coefficient of the first spring is greater than the elasticity coefficient of the second spring.
Preferably, described inner chamber is cylindrical.
Preferably, described cavity is cylindrical.
In the present invention, when moving iron core is during in power failure state, because the elasticity coefficient of the first spring is greater than the elasticity coefficient of the second spring, the elastic force that the first spring produces is greater than the elastic force that the second spring produces, under the comprehensive function of the first spring, the second spring, moving iron core is to moving away from static iron core direction, thereby drive strut, to valve, stifled formation promotes, valve is stifled to be sealed inlet hole and air outlet hole near valve body, thereby cuts off the gas flow between inlet hole and air outlet hole; When moving iron core is in the time obtaining electricity condition, under the elastic force effect of magnetic force and the generation of the second spring, moving iron core is to moving near static iron core direction, thereby drive strut, to valve, stifled formation pulls, valve is stifled away from inlet hole and air outlet hole, thereby is communicated with the gas flow between inlet hole and air outlet hole; Owing to adopting dual spring, can make switch electromagnetic valve operate steadily cutting off in gas handshaking procedures, opening in gas handshaking procedures operation rapidly.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of switch electromagnetic valve of proposing of the present invention.
Embodiment
As shown in Figure 1, Fig. 1 is the structural representation of a kind of switch electromagnetic valve of proposing of the present invention.
With reference to Fig. 1, a kind of switch electromagnetic valve that the present invention proposes, comprise valve body, in valve body, be provided with static iron core 6, moving iron core 5, coil, static iron core 6, moving iron core 5 is all arranged in valve body, moving iron core 5 is positioned at static iron core 6 tops, on the end face of moving iron core 5 near static iron core 6, be provided with inner chamber, in above-mentioned inner chamber, be provided with the first spring 9, above-mentioned first spring 9 one end are connected with static iron core 6 and the other end is connected with moving iron core 5, on the end face of moving iron core 5 away from static iron core 6, be provided with strut 7, strut 7 is provided with valve stifled 4 away from moving iron core 5 one end, stifled 4 sides of valve contact with valve interior wall by lining 1, lining 1 is provided with seal ring 8 with valve interior wall part, valve stifled 4 is provided with cavity 11 away from described strut 7 one sides, in above-mentioned cavity 11, be provided with the second spring 10, second spring 10 one end are connected with valve stifled 4 and the other end is connected with valve body, on valve body, be provided with inlet hole 2 and air outlet hole 3 by the stifled 4 positioning control break-makes of valve, the elasticity coefficient of the first spring 9 is greater than the elasticity coefficient of the second spring 10, wherein, inner chamber and cavity 11 are cylindrical.
In the above-described embodiments, when moving iron core 5 is during in power failure state, because the elasticity coefficient of the first spring 9 is greater than the elasticity coefficient of the second spring 10, the elastic force that the first spring 9 produces is greater than the elastic force that the second spring 10 produces, under the comprehensive function of the first spring 9, the second spring 10, moving iron core 5 is to moving away from static iron core 6 directions, thereby drive strut 7 that valve stifled 4 is formed and promoted, valve stifled 4 seals inlet hole 2 and air outlet hole 3 near valve body, thereby cuts off the gas flow between inlet hole 2 and air outlet hole 3; When moving iron core 5 is in the time obtaining electricity condition, under the elastic force effect producing at magnetic force and the second spring 10, moving iron core 5 is to moving near static iron core 6 directions, thereby drive strut 7 that valve stifled 4 is formed and pulled, valve stifled 4 is away from inlet hole 2 and air outlet hole 3, thus the gas flow between connection inlet hole 2 and air outlet hole 3; Owing to adopting dual spring, can make switch electromagnetic valve operate steadily cutting off in gas handshaking procedures, opening in gas handshaking procedures operation rapidly.
