[0032] Reference below Figure 1-Figure 2 A test system 100 for a breakaway valve test according to an embodiment of the present invention is described.

[0033] like Figure 1 and Figure 2 As shown, a test system 100 for testing a breakaway valve according to an embodiment of the present invention is used to detect the performance of the breakaway valve, and includes: a detection component 1, an air intake component 2, a boost component 3, a refrigeration component 4, an exhaust component 5 and a control component 6; wherein the detection component 1 includes a detection cabin 11, the detection cabin 11 includes a cabin body and a cabin door, the cabin body is provided with a detection cavity, the breakaway valve is placed in the detection cavity, and the cabin door is rotatably connected to the cabin body to open or close the opening of the cabin body.

[0034] The air intake assembly 2 includes an air intake pipe 21; the air intake pipe 21 can deliver test gas to the breakaway valve.

[0035] The booster assembly 3 includes a booster 31, which is arranged on the intake pipe 21 to boost the test gas in the intake pipe 21 so as to provide high-pressure test gas for the breakaway valve for pressure testing, leakage testing, cycle testing, etc. of the breakaway valve.

[0036] The refrigeration assembly 4 includes a refrigerator 41, which is arranged on the air inlet pipe 21 and located between the supercharger 31 and the detection chamber 11. The refrigerator 41 can cool the test gas so as to perform a low-temperature test on the breakaway valve.

[0037] The air intake pipe 21 between the supercharger 31 and the refrigerator 41 is provided with a first flow channel 211 and a second flow channel 212. One end of the first flow channel 211 and the second flow channel 212 are both connected to the supercharger 31, and the other end of the first flow channel 211 is connected to the refrigerator 41. An air inlet is provided on the cabin body, and the air inlet is connected to the break valve and the other end of the second flow channel 212 or to the break valve and the refrigerator 41. A first control valve 2111 is provided on the first flow channel 211, and a second control valve 2121 is provided on the second flow channel 212.

[0038] In this embodiment, the first flow channel 211 and the second flow channel 212 can divert the test gas flowing out of the supercharger 31. When a low-temperature test is required, the first control valve 2111 is opened and the second control valve 2121 is closed to connect the first flow channel 211 and allow the test gas to flow through the refrigerator 41 for cooling. When a low-temperature test is not required, the first control valve 2111 is closed and the second control valve 2121 is opened to connect the second flow channel 212 and allow the test gas to flow directly into the breakaway valve.

[0039] The exhaust assembly 5 includes a first exhaust pipe 51, which is connected to the break valve to discharge the test gas in the break valve. The first exhaust pipe 51 is provided with a third control valve 511 and a one-way valve 7. When the break valve test is completed, the third control valve 511 is opened, the first exhaust pipe 51 is connected, and the test gas in the break valve can be discharged from the first exhaust pipe 51. The one-way valve 7 can prevent gas backflow, thereby ensuring the safety of the test system.

[0040] The supercharger 31, the refrigerator 41, the first control valve 2111, the second control valve 2121 and the third control valve 511 are all electrically connected to the control component 6, and the control component 6 can control the opening or closing of the supercharger 31, the refrigerator 41, the first control valve 2111, the second control valve 2121 and the third control valve 511 to enable the test system to operate normally.

[0041] In some embodiments, the test gas is hydrogen.

[0042] In some embodiments, both the gas outlet end of the second flow channel 212 and the gas outlet end of the refrigerator 41 are provided with a one-way valve 7 .

[0043] According to the test system 100 for testing a breakaway valve according to an embodiment of the present invention, by providing a pressurizing component 3 and a refrigeration component 4, the test system can perform pressure testing, leakage testing, cycle testing, pre-cooling hydrogen exposure and other tests on the breakaway valve.

[0044] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the boost assembly 3 also includes a low-pressure gas storage tank 32 and a high-pressure gas storage tank 33. The low-pressure gas storage tank 32 and the high-pressure gas storage tank 33 are both arranged on the intake pipe 21. The low-pressure gas storage tank 32 is located on one side of the intake end of the supercharger 31, and the high-pressure gas storage tank 33 is located on one side of the outlet end of the supercharger 31.

[0045] In this embodiment, both the low-pressure gas tank 32 and the high-pressure gas tank 33 can store test gas so that the test gas can be delivered to the break valve at any time; after the test gas enters the air intake pipe 21, it will flow into the low-pressure gas tank 32 and be stored in the tank. After the test gas flows out of the low-pressure gas tank 32 and is pressurized by the supercharger 31, it will flow into the high-pressure gas tank 33 and be stored in the tank. When the test requires high-pressure test gas, the high-pressure gas tank 33 can immediately release the high-pressure test gas to allow it to flow to the break valve.

[0046] In a specific embodiment of the present invention, Figure 1 and Figure 2As shown, a first pressure sensor 321 is provided at the low-pressure gas storage tank 32, a fourth control valve 322 and a one-way valve 7 are provided at the air inlet end of the low-pressure gas storage tank 32, a second pressure sensor 331 is provided at the high-pressure gas storage tank 33, a flow meter 332 is provided at the air outlet end of the high-pressure gas storage tank 33, a fifth control valve 213 is provided on the air inlet pipe 21 between the supercharger 31 and the high-pressure gas storage tank 33, and the first pressure sensor 321, the second pressure sensor 331, the flow meter 332, the fourth control valve 322 and the fifth control valve 213 are all electrically connected to the control component 6.

[0047] In this specific embodiment, the first pressure sensor 321 can monitor the gas pressure in the low-pressure gas tank 32, and the second pressure sensor 331 can monitor the gas pressure in the high-pressure gas tank 33. Both the first pressure sensor 321 and the second pressure sensor 331 can transmit the gas pressure signal to the control component 6. If the gas pressure signal is greater than the preset pressure threshold in the control component 6, the control component 6 can control the fourth control valve 322 and / or the fifth control valve 213 to close to prevent the gas from continuing to flow into the low-pressure gas tank 32 and / or the high-pressure gas tank 33, so as to avoid the gas pressure in the gas tank from being too high and causing an explosion. In this way, the overall safety performance of the test system is improved.

[0048] In addition, the one-way valve 7 can prevent gas backflow, thereby improving the gas storage efficiency; the flow meter 332 can monitor the test gas flowing out of the high-pressure gas storage tank 33, and transmit the monitored gas flow signal to the control component 6. If the gas flow is too small and does not meet the test requirements, the control component 6 can issue a prompt in time to remind the test personnel that the flow is too small, so as to promptly detect the test system and eliminate the fault.

[0049] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the exhaust assembly 5 also includes a second exhaust pipe 52, which is connected to the intake pipe 21 and is arranged close to the air inlet. In this embodiment, the test gas in the intake pipe 21 can be discharged through the second exhaust pipe 52, so that when the intake pipe 21 is tested next time, it can ensure that there is no residual test gas in the pipe body, thereby avoiding the residual test gas affecting the accuracy of the next test.

[0050] In a specific embodiment of the present invention, Figure 1 and Figure 2As shown, the second exhaust pipe 52 is provided with a third flow channel 521 and a fourth flow channel 522. One end of the third flow channel 521 and the fourth flow channel 522 are both connected to the outlet end of the second exhaust pipe 52. The third flow channel 521 is provided with a sixth control valve 5211 and a one-way valve 7. The fourth flow channel 522 is provided with a safety valve 5221. When the pressure value in the fourth flow channel 522 exceeds the set threshold of the safety valve 5221, the safety valve 5221 opens, and the sixth control valve 5211 is electrically connected to the control component 6.

[0051] In this specific embodiment, when it is necessary to discharge the residual test gas in the intake pipe 21, the control component 6 controls the sixth control valve 5211 to open so that the test gas can be discharged through the third flow channel 521. At this time, part of the test gas enters the fourth flow channel 522 at the same time. Since the safety valve 5221 is in a normally closed state, the test gas cannot be discharged through the fourth flow channel 522. If the pressure value of the test gas in the fourth flow channel 522 is greater than the set threshold value of the safety valve 5221, the safety valve 5221 will open to allow the test gas to be discharged through the fourth flow channel 522. In this way, the gas pressure in the second exhaust pipe 52 can be quickly reduced to avoid the occurrence of pipeline rupture due to excessive pressure, thereby effectively improving the safety of the test system.

[0052] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, a third pressure sensor 214 and a temperature sensor 215 are provided on the air inlet 21, and the third pressure sensor 214 and the temperature sensor 215 are both provided at the air inlet, and the third pressure sensor 214 and the temperature sensor 215 are both electrically connected to the control unit. In this embodiment, the third pressure sensor 214 can monitor the gas pressure value at the air inlet in real time, and the temperature sensor 215 can monitor the gas temperature at the air inlet in real time; the control component 6 can judge whether the pressure and temperature of the test gas meet the test requirements according to the received gas pressure signal and gas temperature signal, and if not, the control component 6 can issue a prompt in time to remind the test personnel, so as to detect the test system in time and eliminate the fault.

[0053] In one embodiment of the present invention, Figure 1 and Figure 2As shown, a circulation device 111, a heat exchange device 112 and a refrigeration device 113 are provided in the detection chamber. The heat exchange device 112 is used to increase the gas temperature in the detection chamber, the refrigeration device 113 is used to reduce the gas temperature in the detection chamber, and the circulation device 111 is used to circulate the gas in the detection chamber. In this embodiment, the heat exchange device 112 and the refrigeration device 113 can adjust the ambient temperature and humidity in the detection chamber to create a test environment that meets the test requirements; the circulation device 111 can promote the air circulation in the detection chamber 11, so that the ambient temperature of each part in the detection chamber 11 is relatively balanced, so as to create a test environment with a relatively stable ambient temperature.

[0054] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the air intake component 2 also includes a test gas pipeline 22 and a first purge gas pipeline 23. The test gas pipeline 22 and the first purge gas pipeline 23 are both connected to the air intake end of the air intake pipe 21. The test gas pipeline 22 is provided with a seventh control valve 221 and a one-way valve 7. The first purge gas pipeline 23 is provided with an eighth control valve 231 and a one-way valve 7. The seventh control valve 221 and the eighth control valve 231 are electrically connected to the control component 6.

[0055] In this embodiment, the test gas pipeline 22 is used to deliver the test gas to the intake pipe 21 to maintain the normal progress of the test, and the first purge gas pipeline 23 is used to deliver the purge gas to the intake pipe 21. The purge gas is used to blow the residual test gas in the intake pipe 21 out of the intake pipe 21 to clear the intake pipe 21, which not only prevents the residual test gas from corroding the intake pipe 21, but also prevents the residual test gas from affecting the next test. The control component 6 can control the opening and closing of the seventh control valve 221 and / or the eighth control valve 231 so that the test gas or the purge gas can enter the intake pipe 21 in time.

[0056] In a specific embodiment of the present invention, Figure 1 and Figure 2 As shown, the air intake assembly 2 further includes a second purge gas pipeline 24, which is connected to the detection chamber, and a one-way valve 7 is provided on the second purge gas pipeline 24. The exhaust assembly 5 further includes a third exhaust pipe 53, which is connected to the detection chamber. In this specific embodiment, the second purge gas pipeline 24 can deliver purge gas to the detection chamber, and the purge gas can replace the air in the detection chamber to prevent impurities in the air from affecting the detection of the detection device, thereby ensuring the normal operation of the detection device, and at the same time, reducing the hydrogen and oxygen concentration in the detection chamber to avoid explosion and ensure the safety of the test.

[0057] In some embodiments, the purge gas is nitrogen.

[0058] In a specific embodiment of the present invention, Figure 1 and Figure 2 As shown, an exhaust fan 531 is provided on the third exhaust pipe 53, and a hydrogen and oxygen concentration sensor 114 is provided in the detection chamber. The hydrogen and oxygen concentration sensor 114 monitors the concentration of hydrogen and oxygen in the detection chamber in real time, and transmits an electrical signal to the control component 6, so that the control component 6 controls the opening or closing of the exhaust fan 531. In this specific embodiment, when the hydrogen and oxygen concentration signal received by the control component 6 is higher than the preset hydrogen and oxygen concentration value, the control component 6 controls the exhaust fan 531 to open, and controls the second purge gas pipeline 24 to continuously deliver purge gas to the detection chamber, so as to quickly discharge the hydrogen and oxygen in the detection chamber, reduce the hydrogen and oxygen concentration value in the detection chamber, and ensure the safety of the detection chamber.
