Abstract
The invention discloses a switch electromagnetic valve, which comprises a valve body, wherein a static iron core, a movable iron core and a coil are arranged in the valve body, the static iron core is arranged at the lower part of the valve body, the movable iron core is arranged above the static iron core in the valve body, an inner cavity is arranged on the end surface of the movable iron core, a first spring is arranged in the inner cavity, a support rod is arranged on the other end surface of the movable iron core, a sealing cover is sleeved on the support rod, a top block is arranged at the upper end of the support rod, a second spring is sleeved on the top block, a step surface is arranged on the outer peripheral surface of the top block, one end surface of the second spring is in contact with the step surface, and the; the elastic force of the first spring is greater than the elastic force of the second spring. Because kicking block and movable iron core are independent parts, quiet iron core only need overcome the elasticity of first spring, and need not overcome the effort that the negative pressure of vacuum source pair kicking block formed, actuation voltage is less, the coil outage, the elasticity of first spring will do all can the power transmission for the kicking block through movable iron core and bracing piece, the kicking block is pushed up to the vacuum source connecting pipe, the elasticity of first spring is far greater than the second spring, the kicking block can laminate rapidly with the vacuum source connecting pipe, the return speed is fast, the outage return is fast.
Description
Technical field
The present invention relates to a kind of electromagnetic coil switch driven solenoid valve that passes through, belong to automobile and use the switch electromagnetic valve field.
Background technique
The existing employed switch electromagnetic valve of automobile, as shown in Figure 1, through the moving iron core 21 of electromagnetic coil energising static iron core 16 adhesives; And Sealing 20 is one with moving iron core 21 through interference fit; The suction of static iron core 16 must overcome the making a concerted effort of negative pressure that spring 18 and vacuum source connecting tube 19 vacuumize formation, and break connecting tube 17 and vacuum source connecting tube 19 are communicated with, and when outage; 21 of moving iron cores lean on the active force of spring 18 to be pushed up back vacuum source connecting tube 19; This moment, atmosphere access tube 15 communicated with break connecting tube 17, and this structure exists pick-up voltage big, and the outage return waits shortcoming slowly.
Summary of the invention
It is short that technical problem to be solved by this invention provides a kind of response time, the switch electromagnetic valve that pick-up voltage is little, return is fast.
Switch electromagnetic valve of the present invention is realized through following technological scheme:
A kind of switch electromagnetic valve comprises valve body, is provided with static iron core, moving iron core, coil in the valve body; Static iron core is arranged on the bottom of valve body, and moving iron core is arranged on the top of static iron core in the valve body, and said moving iron core is provided with inner chamber in the face of the end face of static iron core; Be provided with first spring in the inner chamber, the other end of moving iron core is provided with strut, is set with sealing cover on the strut; The upper end of strut is provided with jacking block, is set with second spring on the jacking block, and the jacking block outer circumferential face is provided with step surface; One end face of second spring contacts with step surface, and the other end of second spring contacts with an interior edge face on valve body top.
The elastic force of first spring is greater than the elastic force of second spring.
Beneficial effect: switch electromagnetic valve of the present invention, because jacking block and moving iron core are parts independently, so static iron core only need overcome the elastic force of first spring; And need not overcome through the active force of the vacuum source in the logical inlet valve body of vacuum source connecting tube to the negative pressure formation of jacking block, pick-up voltage is less, coil one outage; The elastic force of first spring passes to jacking block through moving iron core and strut 5 with power, and jacking block is pushed up to the vacuum source connecting tube, because the elastic force of first spring is greater than the elastic force of second spring; So jacking block and vacuum source connecting tube can be fitted rapidly; Return speed is fast, and the outage return is fast, can accurately control the connection and the shutoff of source of the gas.
Description of drawings
Fig. 1 is the structural representation of switch electromagnetic valve in the existing technology;
Fig. 2 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is described further.
A kind of switch electromagnetic valve comprises valve body 1, is provided with static iron core 9, moving iron core 6, coil 7 in the valve body 1; Static iron core 9 is arranged on the bottom of valve body 1, and moving iron core 6 is arranged on the top of static iron core 9 in the valve body 1, and moving iron core 6 is provided with inner chamber in the face of the end face of static iron core 9; Be provided with first spring 8 in the inner chamber; The other end of moving iron core 6 is provided with strut 5, is set with sealing cover 4 on the strut 5, and the upper end of said strut 5 is provided with jacking block 3; Be set with second spring 2 on the said jacking block 3; The end face that jacking block 3 outer circumferential faces are provided with step surface 14, the second springs 2 contacts with step surface 14, and the other end of second spring 2 contacts with an interior edge face 13 on valve body 1 top.
The elastic force of first spring 8 is greater than the elastic force of second spring 2.
As shown in Figure 2, switch electromagnetic valve is under "on" position; Moving iron core 6 moves downward and static iron core 9 is fitted, because jacking block 3 and moving iron core 6 are parts independently, so 9 need of static iron core overcome the elastic force of first spring 8; And need not overcome through the active force of the vacuum source in the vacuum source connecting tube 11 logical inlet valve bodies 1 to the negative pressure formation of jacking block 3, pick-up voltage is less, and this moment, vacuum source connecting tube 11 communicated with break connecting tube 12; Coil one outage, the elastic force of first spring 8 passes to jacking block 3 with strut 5 with power through moving iron core 6, and jacking block 3 is pushed up to vacuum source connecting tube 11; Because the elastic force of first spring 8 is much larger than second spring 2; So jacking block 3 can be fitted rapidly with vacuum source connecting tube 11, return speed is fast, and this moment, atmosphere access tube 10 communicated with break connecting tube 12.
