Embodiment
Shown in Fig. 4-6, in an embodiment of solenoid valve of the present utility model, comprise yoke 11, secured core 12, seal ring 13, spring 14, movable core 15, bobbin 16, coil 17 and loam cake 18.This coil 17 is wound on the bobbin 16, as the element of power input, by to the conducting of coil 17 or by, cooperate the effect of spring 14, drive the motion of movable core 15.
The bobbin 16 of present embodiment is for having the integral type bobbin 16 of a side opening hollow cavity.It is included in the rolling part 161 of medium position setting and the interface 162 that is provided with on top.This coil 17 can be wound on the rolling part 161, and introduces power supply by lead 19; And upper interface 162 is provided with the first passage 163 that is communicated with the hollow cavity of bobbin 16, and this first passage 163 can be used as outlet passageway.This upper interface 162 is as link, and outwards outstanding the extension is connected with the pipeline of outside above rolling part 161 gets, and by first passage 163 hollow cavity is communicated with external pipe.Further, also be provided with the second channel 164 that is communicated with hollow cavity, can be used as disappointing passage, as the passage of exhaust, liquid on the top of bobbin 16.
Yoke 11 is " U " type substantially as the assembly of whole solenoid valve, comprises the base plate 111 that is provided with perforate 113 and the upwardly extending side plate 112 in the both sides of base plate 111.This bobbin 16 opening end stretch out and be provided with the joint 165 of fixedlying connected with yoke 11 base plates 111, this joint 165 is placed on the base plate 111 of yoke 11, further, under the suppression by loam cake 18, bobbin 16 is compressed in the space that base plate 111 and side plate 112 surround.
This secured core 12 is provided with the third channel 121 of perforation, and this third channel 121 is communicated with the hollow cavity of bobbin 16, can be used as gas-entered passageway, introduces gas, liquid etc.This secured core 12 is fixedly mounted in the perforate 113 of yoke 11 base plates 111, and at least one section opening side from bobbin 16 is inserted into the hollow cavity of bobbin 16, and one section the outer race that is inserted into hollow cavity at secured core 12 is provided with seal ring 13, seal ring 13 joins with the sidewall sealing of hollow cavity, thereby plays the effect of sealing.
This movable core 15 inserts and is arranged in the hollow cavity of bobbin 16, and is provided with the slit between the inwall of the outer wall of movable core 15 and hollow cavity, for gas, liquid provide a runner.In the present embodiment, the sectional shape of this movable core 15 is a cydariform, thereby makes movable core 15 form the slit between hollow cavity.And spring 14 pretensions are installed between secured core 12 and the movable core 15, utilize the elastic-restoring force of spring 14 to promote the limit position upwards that remains on of movable core 15.Also be respectively equipped with the sealing gasket 151 relative with second channel 164 and third channel 121 at the two ends up and down of movable core 15, as adopt elasticity such as rubber preferably soft material make, play the effect of sealing second channel 164 and third channel 121 respectively.Further, the inboard of this second channel 164 forms projection 166, and the cross sectional area of this projection 166 is less than the cross sectional area of the sealing gasket 151 of movable core 15 upper ends, thereby makes that sealing pad 151 can complete closed projection 166, has good sealing effect; Same, form projection 122 in the inboard of third channel 121, the cross sectional area of this projection 122 is less than the cross sectional area of the sealing gasket 151 of movable core 15 lower ends, thereby makes that sealing gasket 151 can complete closed projection 166, has good sealing effect.
During assembling, secured core 12 is fixedly mounted in the perforate 113 of yoke 11, then seal ring 13 is set on the secured core 12; Coil 17 is wound on the rolling part 161 of bobbin 16, and sealing gasket 151 is installed in the two ends up and down of movable core 15 respectively, then spring 14 is arranged on the position between movable core 15 and the secured core 12, again movable core 15 is inserted into the hollow cavity of bobbin 16; Then bobbin 16 is nested on the secured core 12, again the joint 165 of bobbin 16 bottoms is fixedlyed connected with the base plate 111 of yoke 11, cover loam cake 18 at last, bobbin 16 is compressed in the yoke 11, finish assembling.The utility model has avoided prior art air outlet adapter need be installed to the trouble of loam cake, and reduced the link position that needs sealing, thereby the chance that has reduced gas leakage or revealed has that rational in infrastructure, good sealing effect, saving of work and time, cost are low, environmental protection and energy saving, advantage such as easy to assembly.
As shown in Figure 5, when solenoid valve is in not "on" position, movable core 15 is under the promotion of spring 14, be positioned at limit position upwards, the import of the sealing gasket 151 open third channels 121 of movable core 15 bottoms, gas, liquid can enter by third channel 121, pass through the slit between movable core 15 and the hollow cavity then, flow out to external pipe through first passage 163 again; At this moment, the sealing gasket 151 sealing second channels 164 at movable core 15 tops, thus realize the inflation of external pipe, the effect of liquid.
As shown in Figure 6, and when solenoid valve is switched on, coil 17 conductings, produce magnetic field, adhesive movable core 15, make movable core 15 move downward downward limit position, the import of the sealing gasket of movable core 15 bottoms 151 sealing third channels 121, thus gas, liquid can't enter in the solenoid valve; At this moment, the sealing gasket 151 open second channels 164 at movable core 15 tops, make second channel 164 be communicated with first passage 163, because the supply of gas, liquid, the gas of external pipe, liquid reflux by first passage 163, discharge by second channel 164 again, realized the effect of exhaust, liquid.Thereby switch in the short time at solenoid valve, can realize the function of losing heart; And when solenoid valve cuts off the power supply, realize playing energy-saving and cost-reducing effect by aerification function.
Understandable, solenoid valve of the present utility model is except being the above-mentioned normally closed form, also can be designed as normal open form formula, as long as structures such as the direction of the power of change spring 14 or employing extension spring, the state of above-mentioned solenoid valve energising and outage can be exchanged, that is to say that first passage 163 communicates with third channel 121 when "on" position, and second channel 164 and first passage 163 by; And in when outage, first passage 163 and third channel 121 by, and second channel 164 communicates with first passage 163.This often opens or the normal close type solenoid valve can use third channel 121 air inlets, and first passage 163 is given vent to anger, and second channel 164 loses heart; Perhaps use first passage 163 air inlets, and third channel 121 is given vent to anger, second channel 164 loses heart.
