After opening manually operated valve B301, make into that loop, cabin 1 and deliver from vault reflux circuit 2 forms a path, make propellant agent can be full of into loop, cabin 1 and deliver from vault reflux circuit 3, reach the purpose that into cabin pipeline 106 and deliver from vault return line 303 propellant agents are filled.
Advance cabin pipeline 106 and deliver from vault return line 303 and be welded by steel pipe, steel pipe adopts 45# steel steel pipe, and diameter is 6mm, and wall thickness is 1mm, can satisfy the needs of pressure in the pipeline, sprays paint to handle and prevent to get rusty in the surface, and acidification has been passed through in inside; Elasticity pipeline 204 is that the metal thin tube of 1.5mm is made by diameter 2mm, internal diameter.
The four-way that four-way 205 selects for use Jiangsu Ai Keer pipe-line equipment Co., Ltd to produce.
The concrete steps that the propellant agent of arc heating motor 501 is filled are as follows:
1) closes manually operated valve A102, the monostable solenoid valve C104 in the loop, cabin 1 into, the manually operated valve B301 in the deliver from vault reflux circuit 3; Open the monostable solenoid valve A201 at suction port 206 places of cabin inner looping 2, monostable solenoid valve B203; This moment, cabin inner looping 2 was communicated with vacuum cabin 5, and disconnected with the external world.
Starting vacuum system vacuumizes vacuum cabin 5; Shown in the arrow among Fig. 2, the gas in the cabin inner looping 2 passes through monostable solenoid valve B203 along the pipeline in the cabin, arrives four-way 205, and gas is extracted out from suction port 206 fast through monostable solenoid valve A201 then; Simultaneously, advance in the loop, cabin 1, monostable solenoid valve C104 also passes through monostable solenoid valve A201 to gas between the four-way 205 and the manually operated valve B301 in the deliver from vault reflux circuit 3 to the gas between the four-way 205, extract out fast from suction port 206, it is bigger to have solved in the arc heating motor 501 flow resistance capillaceous like this, extracts the shortcoming of difficulty.
Monostable solenoid valve A201 by suction port 206 places on the four-way 205 opening and closing, make the pipeline in the cabin realize disconnecting and being connected with vacuum cabin 5, like this when cabin inner looping 2 carries out extracting vacuum, gas in the pipeline can be bigger by internal diameter fast, the suction port 206 that flow resistance is very little is extracted out, thereby realized the requirement of cabin inner looping 2 extracting vacuum, for the filling of cabin inner looping 2 propellant agents has solved crucial problem.
2) treat that degree of vacuum reaches 10 in the vacuum cabin 5
-1Pa, the pressure transducer A202 that arranges before four-way 205 can measure the force value in the pipeline, when force value that pressure transducer A202 measures identical with force value in the vacuum cabin 5 or very near the time, reached the cabin inner looping fully, the standard of elasticity pipeline 204 extracting vacuum particularly, this moment, the cabin inner looping 2 reached the requirement that vacuum is filled.
3) pressurized gas enter basin boost-up circuit 4, shown in the arrow among Fig. 1, at first enter knock out drum 406, will filter through the impurity in the pressurized gas of filter C405 then, enter propellant agent basin 101 by manually operated valve C402 control then, propellant agent basin 101 is carried out supercharging;
4) then close the suction port 206 of four-way 205, monostable solenoid valve A201, monostable solenoid valve B203, thereby cut off getting in touch of cabin inner looping 2 and vacuum cabin 5; Open monostable solenoid valve C104, manually operated valve A102, carry out the tapping filling advancing cabin pipeline 106; Because the effect of pressure reduction, shown in the arrow among Fig. 1, the propellant agent in the propellant agent basin 101 flows into into loop, cabin 1.
5) open manually operated valve B301 in the deliver from vault reflux circuit 3, propellant agent flows out along deliver from vault reflux circuit 3, deliver from vault return line 303 is carried out propellant agent fill; Propellant agent flows out along deliver from vault reflux circuit 3, flows in the glass tube 302 through manually operated valve B301, flows out deliver from vault reflux circuit 3 at last, flows in the recovery tower.
6) propellant agent in the glass tube 302 in the monitoring deliver from vault return line 303 when treating that propellant agent no longer is mixed with bubble in the glass tube 302, is closed manually operated valve B301; When just beginning owing to also have gas in the deliver from vault return line 303, flow in deliver from vault return line 303 and the glass tube 302 is the mixture of propellant agent and gas, so sight glass pipe 302 can find that bubble is arranged in the propellant agent at this moment, and when the gas in the pipeline is all discharged, what flow through in the glass tube 302 then is pure propellant agent, no longer contains bubble this moment; So far finishing the into tapping in loop, cabin 1 and deliver from vault reflux circuit 3 fills.
When hydrazine arc heating motor needs propellant feed, open monostable solenoid valve B203, by the connection of pipeline in the switch control vacuum cabin 5 of monostable solenoid valve B203.Monostable solenoid valve B203 is used for accurately controlling the service time of propellant agent.Adopt fast monostable solenoid valve B203 of on-off effect time in the device, the CLK clock that the switch of monostable solenoid valve B203 is sent by data acquistion system is controlled, and has avoided manually-operable to supply with the problem in the reaction time that switch brings; Simultaneously because this monostable solenoid valve B203 in vacuum cabin 5, has realized remote operation by monostable solenoid valve B203.Because in the elasticity pipeline 204 is vacuum, the propellant agent hydrazine just can promptly be filled elasticity pipeline 204, supplies to the arc heating motor, satisfies its job requirement.
Cabin inner looping 2 is by designing the suction port that internal diameter is bigger at four-way 205 places, and by monostable solenoid valve A201 control suction port, make the extracting vacuum of cabin inner looping 2 be easy to realize, the pressure transducer A202 by cabin inner looping 2 can detect the force value in the cabin inner looping 2 simultaneously; The design of deliver from vault reflux circuit 3 makes the propellant agent in loop, cabin 1 into fill and is easy to realize, whether the propellant agent that can observe out loop, cabin 1 and deliver from vault reflux circuit 3 by the glass tube 302 of deliver from vault reflux circuit 3 is filled and finished simultaneously.The pressure transducer A202 of cabin inner looping 2 and the glass tube 302 of deliver from vault reflux circuit 3 make whole filling process be convenient to observe and operation.
The monostable solenoid valve A201 that whether opens suction port 206 places of four-way 205 is contrasted during to extracting vacuum in the test.Degree of vacuum reaches 10 in vacuum cabin 5
-1During Pa, at first the monostable solenoid valve A201 at suction port 206 places of four-way 205 is not opened in selection, and this moment, discovery changed extremely slow by the force value in the pressure transducer A202 monitoring cabin inner looping 2, and after 10 minutes, force value has only reached 4.3 * 10
4Pa is far from reaching the requirement of extracting vacuum; Open the monostable solenoid valve A201 at suction port 206 places of four-way 205 then, force value has quickly fallen to 10 about 10 seconds
-1Pa has reached the requirement of extracting vacuum.Evidence, the ingenious design of four-way 205 place's suction ports 206 makes the vacuum of cabin inner looping 2 fill the realization easily that becomes, and can save a lot of time.For the development and the application of low-power hydrazine arc heating motor 501 provides the good premise guarantee.
