Embodiment
As shown in Figure 1, electromagnetic impulse valve of the present utility model, comprise main valve body 1, cover the large diaphragm 3 of main valve body 1 bottom, be arranged on the air outlet 13 and the auxiliary valve body 11 that is arranged on main valve body 1 top of main valve body 1 one sides, be main cavity 2 between described main valve body 1 and the large diaphragm 3, the bottom of described main valve body 1 is provided with suction port 4, be provided with Small diaphragm-piece 12 between described auxiliary valve body 11 and the main valve body 1, it is secondary cavity 8 between described auxiliary valve body 11 and the Small diaphragm-piece 12, be provided with little spring 10 in the described secondary cavity 8, be socketed with armature 14 in the described little spring 10, described Small diaphragm-piece 12 is provided with the exhaust port that links to each other with air outlet 13, described armature 14 is inserted in the exhaust port, be provided with the vent 7 that is connected between described main cavity 2 and the secondary cavity 8, the top of described auxiliary valve body 11 is provided with the electromagnetic coil 9 of control armature 14 usefulness; Be provided with big spring 6 in the described main cavity 2, be socketed with air inlet slide block 5 in the described big spring 6, described air inlet slide block 5 is inserted in the suction port 4.
In the time of concrete the use, be connected with air outlet 13 respectively at suction port 4 with tracheae, air inlet slide block 5 retreats at the effect lower compression big spring 6 of gas pressure, gas enters main cavity 2, and then enters secondary cavity 11 by vent 7, because main cavity 2 is identical with pressure in the secondary cavity 11, this moment, Small diaphragm-piece 12 abutted against on the air outlet 13, air outlet 13 is blocked, and at this moment, whole gas circuit is in closed condition.
Give 9 one pulse signals of electromagnetic coil, under the effect of the electromagnetic force of electromagnetic coil 9, armature 14 retreats, exhaust port is opened, gas in the secondary cavity 8 13 is discharged from the air outlet, and the air pressure in the secondary cavity 8 reduce and the air pressure in the main cavity 2 gradually, and this moment, Small diaphragm-piece 12 was away from air outlet 13, air outlet 13 is opened, and this moment, whole gas circuit was in opening state.
By the time after the pulse signal ends, armature 14 resets, vent closure, air pressure in the secondary cavity 8 raises gradually and air pressure final and in the main cavity 2 equates, this moment, Small diaphragm-piece 12 abutted against on the air outlet 13, and air outlet 3 is blocked, and this moment, whole gas circuit was in closed condition once more.
Therefore, electromagnetic impulse valve of the present utility model, simple in structure, the reach by electromagnetic coil 9 control armature 14 and retreating realizes the closing and opening of exhaust port, and the final control that realizes gas path on-off, thereby highly sensitive.
The utility model is not limited to above-mentioned mode of execution, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technological scheme, all fall within the protection domain of the present utility model.
