Below by taking low thrust liquid engine as an example, the operation principle of the two-way electromagnetic valve of above structure is described：
It needs to use two-way electromagnetic valve on low thrust liquid engine, to control the switch of two pipelines simultaneously, wherein
One Pipeline transport strong oxidizer, another Pipeline transport deep-etching fuel when work, need fuel road to be opened prior to oxidant road
Open 0-2ms, fuel road is closed than oxidant road delay 0-2ms when closing, i.e., fuel Lu Yaoxian is closed after opening, and oxidant Lu Yaohou
It opens and first closes.
Therefore when installing two-way electromagnetic valve described in the present embodiment, one 8 lower end medium runner of spool corresponds to and oxidant road
Connection, and 2 10 lower end medium runner correspondence of spool is connect with fuel road.
When being powered to electromagnet, electromagnetic attraction is generated, armature 2 moves upwards under the action of electromagnetic attraction, drives valve
The drawstring 2 11 of core 2 10 overcomes 801/1001 elastic force of diaphragm to move upwards, once spool 2 10 moves upwards, then spool 2 10
The runner of lower end closed is opened；When armature 2 continues up, drawstring 1 is gradually tightened, as armature 2 continues up fortune
Dynamic, spool 1 is pulled up by drawstring 1, and the medium runner of one 8 lower end of spool is opened；Until armature 2 moves to and static iron core
1 lower face is bonded, and two groups of medium runners fully open.
In the state of above-mentioned fully open, the elastic force F1 that the diaphragm 801 on spool 1 generates is two groups of medium runners：
F1=K1* (b1+t-t1), the elastic force F2 that the diaphragm 1001 on spool 2 10 generates are：F2=K2* (b2+t) is made by design
801 stiffness K 1 of diaphragm on spool 1 is more than 1001 stiffness K 2 of diaphragm on spool 2 10, it is ensured that 1.2F2≤F1≤1.4F2；
Wherein, b1 is the initial deformation amount of one 8 diaphragm 801 of spool, and b2 is the initial deformation amount of 2 10 diaphragm 1001 of spool,
T is the range of armature 2, and t1 is that armature 2 pulls spool 1 to start the stroke before action.
Since spool 2 10 is acted prior to spool 1, the length travel of spool 2 10 is more than the longitudinal position of spool 1
It moves, after electromagnet dead electricity, armature 2 is detached from static iron core 1 and moves downward, and the tensile force of drawstring 1 and drawstring 2 11 is released from, valve
Core 1 and spool 2 10 lose the pulling force of corresponding drawstring, the spool 1 under the action of corresponding 801/1001 elastic-restoring force of diaphragm
It is moved downward along spool mounting hole 15 for 2 10 times with spool, until spool 1 and 2 10 lower end of spool are by corresponding medium runner
It closes.Since the upward length travel of spool 2 10 is more than the upward length travel of spool 1, simultaneously because F2≤F1, therefore
In spool return, the return time of spool 2 10 will be later than spool 1, spool 2 10 may be implemented with this first open to close afterwards, and
The purpose first closed is opened after spool 1.
In conjunction with above-mentioned operation principle, the embodiment of the present invention is done as described below：
In the above-described embodiments, drawstring 2 11 remains tensioned state, and the original state of drawstring 1 is relaxation shape
State, according to 2 length travel of requirement and armature for the time interval opened to spool 1 and spool 2 10 under particular condition in use
Speed, the length or slackness needed for drawstring 2 11 can be calculated.
It these are only the preferred embodiment of the present invention, be not intended to restrict the invention, for those skilled in the art
For member, the invention may be variously modified and varied.Any modification made by all within the spirits and principles of the present invention,
Equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
