[0027] Figure 1 It is a schematic diagram of a low-temperature immersion device for an electric explosion valve according to an embodiment of the utility model; Figure 2 It is a schematic diagram of a low-temperature immersion device for an electric explosion valve according to another embodiment of the utility model.

[0028] like Figure 1 As shown, the utility model provides a low-temperature immersion device for an electric explosion valve, comprising: an electric explosion valve box 101, inside which the electric explosion valve to be tested is arranged; a liquid nitrogen tank 102, for storing liquid nitrogen and connected to the electric explosion valve box 101 through a first pipeline; an alcohol tank 103, for storing alcohol and connected to the electric explosion valve box 101 through a second pipeline; a nitrogen storage tank 104, for storing nitrogen and connected to the electric explosion valve through a third pipeline.

[0029] Specifically, the low-temperature immersion test of the electric explosion valve can verify whether the relevant performance of the electric explosion valve meets the design requirements and subsequent use requirements under low-temperature conditions. The low-temperature immersion device of the electric explosion valve in this embodiment can realize the joint adjustment of two different low-temperature media, liquid nitrogen and alcohol, so that the temperature of the low-temperature immersion environment required by the electric explosion valve is maintained within a set range.

[0030] In specific operation, when the medium temperature in the electric explosion valve box 101 exceeds the set temperature range, the liquid nitrogen tank 102 is opened to add liquid nitrogen, and when the set temperature range is reached, the liquid nitrogen input is closed. When the medium temperature in the electric explosion valve box 101 is lower than the set temperature range, the alcohol tank 103 is opened to add alcohol, and when the set temperature range is reached, the alcohol input is closed. Among them, the nitrogen provided by the nitrogen storage tank 104 can be energized through the electric explosion valve to complete the supply of high-pressure nitrogen. After the electric explosion valve completes the low-temperature immersion test, if the performance of the electric explosion valve is not affected after the test, the nitrogen pressure on the third pipeline connected to the nitrogen storage tank 104 will be released. If the performance of the electric explosion valve is affected after the test, the pressure on the third pipeline connected to the nitrogen storage tank 104 will not be released, then it is necessary to open the emergency air release valve 208 on the nitrogen storage tank 104.

[0031] By means of the low-temperature immersion device of the electric explosion valve in this embodiment, the low-temperature medium of the electric explosion valve box 101 can be adjusted at any time to ensure that the temperature of the electric explosion valve is maintained during the low-temperature immersion test. Moreover, after completing the immersion test, the device can directly perform the on-off test of the electric explosion valve, ensuring the accuracy of the test data and the rapidity of the test.

[0032] like Figure 2 As shown, according to one embodiment of the utility model, the low-temperature immersion device of the electric explosion valve also includes: a liquid nitrogen regulating valve 201, which is arranged on the first pipeline for controlling the delivery of liquid nitrogen; and an alcohol regulating valve 202, which is arranged on the second pipeline for controlling the delivery of alcohol.

[0033] According to an embodiment of the utility model, the low-temperature immersion device of the electric explosion valve further includes: a high-pressure stop valve 203, which is arranged on the third pipeline to control the delivery of nitrogen.

[0034] According to an embodiment of the present invention, the low-temperature immersion device of the electric explosion valve further includes: a first pressure sensor 204 , which is disposed on the nitrogen storage tank 104 and is used to monitor the pressure of the nitrogen in the nitrogen storage tank 104 .

[0035] According to an embodiment of the present invention, the low-temperature immersion device of the electric explosion valve further includes: a second pressure sensor 205, which is arranged on the third pipeline and is used to monitor the pressure of nitrogen in the third pipeline.

[0036] According to an embodiment of the present invention, the low-temperature immersion device of the electric explosion valve further includes: a temperature sensor 206, which is arranged on the electric explosion valve box 101 to monitor its temperature.

[0037] According to an embodiment of the present invention, the low-temperature immersion device of the electric explosion valve further includes: a medium drain valve 207 , which is arranged at the lower end of the electric explosion valve box 101 and is used to discharge the medium in the electric explosion valve box 101 .

[0038] According to an embodiment of the present invention, the low-temperature immersion device of the electric explosion valve further includes: a vent valve 208, which is arranged on the fourth pipeline and is used to release nitrogen in the electric explosion valve, and the fourth pipeline is connected to the third pipeline.

[0039] According to an embodiment of the utility model, the electric explosion valve comprises an electric explosion tube 301. After the electric explosion valve is soaked in low temperature, the electric explosion tube 301 is energized for testing.

[0040] According to an embodiment of the present utility model, the electric explosion tube 301 is fixed on the electric explosion valve by means of bolts 302 .

[0041] Specifically, remotely controlled regulating valves are arranged on the first pipeline, the second pipeline and the third pipeline, which are respectively a liquid nitrogen regulating valve 201, an alcohol regulating valve 202 and a high-pressure stop valve 203, for controlling the delivery of liquid nitrogen, alcohol and high-pressure nitrogen. Through the setting of the remote regulating valve, the operator can monitor the temperature of the cryogenic medium according to the data of the temperature sensor 206 on the electric explosion valve box 101, so as to open or close the regulating valve. When the temperature output by the temperature sensor 206 in the electric explosion valve box 101 exceeds the set temperature range, the liquid nitrogen regulating valve 201 is opened to add liquid nitrogen, and when the set temperature range is reached, the liquid nitrogen regulating valve 201 is closed. When the temperature output by the temperature sensor 206 in the electric explosion valve box 101 is lower than the set temperature range, the alcohol regulating valve 202 is opened to add alcohol, and when the set temperature range is reached, the alcohol regulating valve 202 is closed.

[0042] In one embodiment, after the low-temperature immersion test of the electric explosion valve is completed, the medium drain valve 207 is opened to discharge the low-temperature medium including liquid nitrogen and alcohol in the electric explosion valve box 101. Next, the electric explosion tube 301 cable is tested for continuity. After the cable continuity test is completed, the high-pressure stop valve 203 on the third pipeline is opened to deliver nitrogen, and the pressure of the first pressure sensor 204 on the nitrogen storage tank 104 and the pressure of the second pressure sensor 205 on the third pipeline are observed to see whether they meet the test requirements. If the requirements are met, the high-pressure stop valve 203 is closed. When the pressure meets the requirements, the electric explosion tube 301 is powered on for testing. If the pressure of the second pressure sensor 205 is released after the electric explosion tube 301 is started, the test is completed, and the low-temperature immersion device of the electric explosion valve is disassembled. If the pressure of the second pressure sensor 205 is not released after the electric explosion tube 301 is started, the air release valve 208 on the fourth pipeline is opened urgently to observe the pressure release of the second pressure sensor 205.

[0043] Among them, the low-temperature immersion device of the electric explosion valve in the present application can be remotely controlled through the real-time temperature of the temperature sensor 206, and the low-temperature medium in the electric explosion valve box 101 is kept within the set temperature range by remotely controlling the on and off of the liquid nitrogen regulating valve 201 and the alcohol regulating valve 202. It has been verified that the electric explosion valve subjected to the low-temperature immersion test by the low-temperature immersion device of the present application can meet its design requirements and the subsequent use requirements, and the device can effectively reduce the manual operation of the staff and avoid safety problems.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
