Specific embodiment
Embodiment 1
As shown in Figure 1, the present embodiment provides a kind of piston type air entraining substation long-tube trailer rupture disk fatigue test device, packet Surge tank 2, reciprocating compressor 4, storage cylinder 11 and recording controller 16 are included, the air inlet side piping connection of surge tank 2 has first Blow valve 1, surge tank 2 go out gas side through 3 piping connection reciprocating compressor 4 of Y-filter, and reciprocating compressor 4 successively passes through Solenoid valve 5,6 piping connection storage cylinder 11 of charging check valve are inflated, the gas side that goes out of charging check valve 6 is sequentially connected through pipeline all the way It unloads pneumoelectric magnet valve 8, direct-operated regulator 7 and is connected to the second blow valve 15, charging check valve 6 goes out gas side through another way pipeline It is sequentially connected the first ball valve 9, rupture disk 10 and the air inlet side for being connected to the second blow valve 15, storage cylinder 11 goes out gas side second 12 piping connection rupture disk 10 of ball valve and the air inlet side for being connected to the second blow valve 15, the air inlet side of storage cylinder 11 and out gas side Be connected separately with first pressure gauge 13 and second pressure gauge 14 on pipeline, 16 signal of recording controller connect reciprocating compressor 4, Inflation solenoid valve 5 unloads pneumoelectric magnet valve 8, first pressure gauge 13 and second pressure gauge 14.
Three phases are mainly divided in pressure change section in the gas cylinder of piston type air entraining substation long-tube trailer: first is that in mother station It is inflated into the gas cylinder of piston type air entraining substation long-tube trailer, pressure rises to 20MPa from 3MPa;Second is that piston type air entraining substation is long Pipe trailer transports gas cylinder to substation from mother station, this Process Gas pressure in the bottle is about maintained at 20MPa;Third is that will be lived by compressor Gas in the gas cylinder of plug air entraining substation long-tube trailer extracts and is pressed into the vehicle bottle of natural gas vehicle, and the pressure of gas cylinder will from 20MPa To 3MPa, it is believed that the gas in gas cylinder has run out.Piston type air entraining substation long-tube trailer rupture disk testing fatigue dress of the invention The pressures cycle period set also mainly includes three phases: first is that aeration phase, second is that packing stage, third is that the gas stage is unloaded, point The above three constant interval of the gas pressure in the bottle of piston type air entraining substation long-tube trailer is not corresponded to.
Pneumoelectric magnet valve 8 is unloaded in aeration phase, closing, opens inflation solenoid valve 5, starts reciprocating compressor 4, through inflating non-return Valve 6 is inflated with the rate of 350Nm3/s or so into storage cylinder 11, and second pressure gauge 14 measures pressure value, is reached to pressure value After 20MPa, the charge operation of storage cylinder 11 terminates, and reciprocating compressor 4 and inflation solenoid valve 5 is closed, into packing stage.It protects Pressure stage, 11 dwell time of storage cylinder about 60s, into the oil return stage.It unloads the gas stage, opens and unload pneumoelectric magnet valve 8, in storage cylinder 11 High pressure gas unloaded pneumoelectric magnet valve 8, direct-operated regulator 7 and the discharge of the second blow valve 15, wherein direct-operated regulator 7 is logical Cross the pressure difference flow automatic regulation of its upstream and downstream.First pressure gauge 13 measures pressure value, drops to gas pressure in storage cylinder 11 After 3MPa, depressed beam is unloaded, pneumoelectric magnet valve 8 is unloaded in closing.After unloading gas, 5s is rested, then start the pressure test in next period, Above-mentioned pressures cycle testing time is 4000 times.Being inflated to storage cylinder 11 or during unload gas, if rupture disk 10 occur it is quick-fried Broken, the gas in storage cylinder 11 flows through under the first ball valve 9 or the second ball valve 12 and rupture disk 10 of 10 upstream tandem of rupture disk The pipeline of trip is discharged through the second blow valve 15, and closes the first ball valve 9 or the second ball valve of 10 upstream tandem of rupture disk in time 12 continue to release to prevent high pressure gas.Because rupture disk 10 be 10 groups, when test pressures cycle number respectively reach 500 times, When 1000 times, 2000 times, 3000 times, 4000 times (or explosion), the 11 each 1 set of rupture disk 10 in front and back of storage cylinder is respectively removed, is carried out quick-fried Broken test, tests its burst pressure.The air inlet side of storage cylinder 11 forms 5 groups through the first ball valve 9, the series connection of rupture disk 10, storage cylinder 11 the second ball valve of gas side 12 out, 5 groups of formation of the series connection of rupture disk 10.Pipeline between rupture disk 10 and the second blow valve 15 is It releases pipeline.Blow valve 1 is used in the inflation of storage cylinder 11, unloads during releasing of storage cylinder 11 after 10 explosion of gas or rupture disk Surge tank 1 and ambient pressure is kept to balance.First pressure gauge 13 is to the air inlet side of storage cylinder 11 and the pipe connecting with rupture disk 10 The pressure on road carries out test and pressure data acquisition, and second pressure gauge 14 is connect to the gas side out of storage cylinder 11 and with rupture disk 10 Pipeline pressure carry out test and pressure data acquisition and data processing.Usually to the pressure test of rupture disk 10, need more Gas operation is unloaded in secondary inflation, pressure maintaining, and to simulate the applying working condition of rupture disk 10, recording controller 16 controls reciprocating compressor 4, inflate solenoid valve 5 and unload the switch of pneumoelectric magnet valve 8, first pressure gauge 13, second pressure gauge 14 by the number pressure of acquisition it is believed that It number is transmitted to recording controller 16, realizes the automatic control of testing fatigue process and the accurate recording of data.
Embodiment 2
It is in place of the present embodiment and the difference of embodiment 1, recording controller 16 is programmable logic controller (PLC), be may be programmed Logic controller high reliablity, strong antijamming capability, can stablize, efficiently control test process operation.Recording controller 16 connect reciprocating compressor 4 through Bluetooth signal, inflation solenoid valve 5, unload pneumoelectric magnet valve 8, first pressure gauge 13 and second pressure Table 14, be omitted reciprocating compressor 4, inflation solenoid valve 5, unload pneumoelectric magnet valve 8, first pressure gauge 13 and second pressure gauge 14 with The connection of 16 signal cable of recording controller facilitates reciprocating compressor 4, inflation solenoid valve 5, unloads pneumoelectric magnet valve 8, first pressure gauge 13 and second pressure gauge 14 installation, and Bluetooth transmission is also more safe and reliable when gas is flammable explosive gas.
Certainly, the above description is not a limitation of the present invention, and the present invention is also not limited to the example above, this technology neck The variations, modifications, additions or substitutions that the technical staff in domain is made within the essential scope of the present invention also should belong to of the invention Protection scope.
