Charging tooling；
(2) gas circuit filling releases interface and is passed through nitrogen, and gas source cavity pressure is P1, igniting agent filling outfall be passed through nitrogen, igniting agent
Cavity pressure is P2, P1> P2；
(3) compound half both sides differential pressure of membrane △ Pg=P1-P2It is squeezed and is adjacent to igniting agent cavity wall, released by igniting agent filling
Interface is vacuumized with nitrogen replacement operator three times；
(4) igniting agent filling releases interface by the external igniting agent charging tooling connection filling tank of igniting agent, and igniting agent is filling
Tank pressure P3, P3=P2, by adjusting gas source cavity pressure P1, so that P1< P2, in pressure difference △ Pd=P3-P1Under the action of, it is compound
Half film starts slowly to overturn to gas source chamber, releases interface from igniting agent filling and igniting agent is sucked igniting agent chamber；
(5) igniting agent filling volume flow V is setdIt is pressure difference △ Pd=P3-P1With the function of local temperature T, i.e. Vd=F (P3-P1,
T), by controlling gas source cavity pressure P1, opening and closing and the igniting agent filling flow of filling process can be precisely controlled；
(6) in igniting agent filling process, the nitrogen of gas source chamber releases interface from gas circuit filling and excludes, and the gas of exclusion passes through outside
The pipeline of gas circuit charging tooling excludes, which is inserted into the flask for holding silicone oil, with air-isolation；
(7) when silicone oil flask bubble-free is emerged, show that igniting agent filling finishes, remove external igniting agent road charging tooling, and fill
It prepares igniting agent filling and releases sealing joint and fastener；
(8) after the completion of filling, compound half film is adjacent to gas source cavity wall, releases interface by gas circuit filling and external gas circuit fills work
Dress is vacuumized with nitrogen displacement three times, final to maintain gas source cavity pressure for P4(P4 is less than), as air cushion；
(9) external gas circuit charging tooling is removed, gas circuit filling is assembled and releases sealing joint and fastener, complete igniting agent filling
Process.
10. one kind can single/repeatedly igniting suction squeeze half membrane type ignition module working method, it is characterised in that step is such as
Under:
(1) when working, pressure P5High pressure gas from ignition module pressurization air source entrance enter, rack pressurization air source and enter membrana oralis
After plate valve, diaphragm valve fracture pressure Pm< P5, half film of extrusion cladding；
(2) compound half film squeezes igniting agent, and racks igniting agent outlet diaphragm valves, fracture pressure Pmm< P5, by igniting agent from point
Fiery agent outlet squeezes out, and into external igniting supply line, completes ignition module work.
