Frequently upspring reduction safety valve service life, safety valve is broken down, and gas cannot be discharged safely, causes the quick-fried of equipment and pipeline
The problem of fried accident.
The utility model has following several workflows：
Workflow one：The aerating of tank car 5, when there is tank car 5 to need inflation, is connected with inflation post 4, manually boots inflation post
Inflation on 4 allows call button, and signal transmission sends instruction to PLC control devices 8, PLC control devices 8 to compressor, permits
Perhaps compressor start, PLC control devices 8 start single respective compressive machine or multiple compressors start simultaneously, open first
The automatic valve 7 of automatic valve 2 and second, compressor possesses start bar by detecting the parameters such as compressor intake and exhaust pressure at different levels, temperature
During part, compressor normally starts, and compressor is by low pressure natural gas by after multi-stage booster, gases at high pressure are entered by discharge duct
First automatic valve 2, the second automatic valve 7, enter inflation post 4 afterwards, and inflation post 4 starts to be the aerating of tank car 5, the gas pressure of tank car 5
Gradually rise, the pressure of tank car 5 is slightly below Compressor Discharge Pressure, until the gas pressure of tank car 5 reaches rated value, PLC control dresses
Put 8 pairs of compressors and send halt instruction, compressor sails out of gas station, this work automatically into shutdown, compressor shutdown, tank car 5
Flow is completed.
Workflow two：The aerating of CNG automobile 13, it is necessary to be the aerating of CNG automobile 13 during workflow one is performed
When, CNG automobile 13 is connected with filling machine 12, filling machine 12 is opened, filling machine 12 sends a signal to PLC control devices 8, PLC
Control device 8 sends instruction, opens the 3rd automatic valve 11, closes the second automatic valve 7, and compressor is by low pressure natural gas by multistage
After supercharging, gases at high pressure are sent into by the first automatic valve 2, the 3rd automatic valve 11 by discharge duct, afterwards into filling machine 12, plus
Mechanism of qi 12 starts to be the aerating of CNG automobile 13.Because the initial pressure of CNG automobile 13 is relatively low, far below pressure (this practicality of counterbalance valve 3
It is new to be preferably 19.5MPa), so compressor air-discharging can preferentially enter CNG automobile 13, gas pressure in the gas bomb of CNG automobile 13
Power is quickly raised, and the pressure of CNG automobile 13 is slightly below Compressor Discharge Pressure；Until the gas pressure of CNG automobile 13 reaches counterbalance valve 3
Pressure (is typically set at 19.5MPa), and counterbalance valve 3 is stressed influence, automatically turns on, and compressor gases at high pressure pass through discharge duct
Into the first automatic valve 2, counterbalance valve 3, enter and inflate post 4, inflation post 4 is the aerating of tank car 5, now, tank car 5 and CNG vapour afterwards
The aerating simultaneously of car 13, because the gas bomb of tank car 5 is larger, does not result in pressure and raises immediately, at this moment can close filling machine
12, air filling gun is extracted, stopping carries out aerating to CNG automobile 13, and CNG automobile 13 sails out of gas station, and this workflow is completed.If
Without filling machine 12 is closed in time, additional effect will not be caused to the system, only when tank car 5 and the gas pressure of CNG automobile 13
Rated value is reached simultaneously, and PLC control devices 8 can just send halt instruction, compressor autostop, if necessary to right to compressor
The aerating of second or more CNG automobile 13, repeats this flow.
Note, only workflow one is carrying out, can implementation flow two, that is, ensure that compressor all the time can be to groove
Car 5 carries out aerating, can open compressor.Because the mounted gas cylinder of CNG automobile 13 often only has tens liter capacities, only to CNG
During 13 aerating of automobile, will soon fill it up with, if compressor cannot stop in time or gas is without remaining storing apparatus, gas pressure
Power will be raised quickly, and compressor air-discharging safety valve can cause compressor fault to shut down, together because being upspring more than specified set-pressure
When safety valve frequently upspring, will reduce safety valve service life；If other safety valve breaks down, gas cannot be arranged safely
Go out, the explosion accident of equipment and pipeline can be caused, tank car 5 can play the effect of caisson, evade above-mentioned risk, while rising
To buffer gas, accelerate the purpose of aeration speed.
General principle of the present utility model, principal character and advantage has been shown and described above.The technical staff of the industry
It should be appreciated that the utility model is not restricted to the described embodiments, the simply explanation described in above-described embodiment and specification is originally
The principle of utility model, on the premise of the utility model spirit and scope are not departed from, the utility model also has various change
And improvement, these changes and improvements are both fallen within the range of claimed the utility model.The utility model claims scope
Defined by appending claims and its effect thing.
