[0106] The irradiation supervision tube product is made by welding parts such as a semi-tank shell, and various internal parts are installed inside and filled with helium gas. It is the piece to be autoclaved.

The gas autoclaving device and the liquid autoclaving device share the irradiation supervision tube, the high-pressure chamber, the high-temperature chamber, the temperature measurement and display system, and the pressure measurement and display system, and the rest are not shared.

[0110] This embodiment adopts the method and device of "positive pressure" autoclaving with a gas medium. The method of "positive pressure" autoclaving with a gas includes the following steps: a.

As Figure 4 shown, it is the gas medium autoclaving device adopted in this embodiment. As Figure 5 shown, it is the liquid medium autoclaving device adopted in this embodiment. Both autoclaving devices include a shared irradiation supervision tube, high-pressure chamber, high-temperature chamber, temperature measurement and display system, and pressure measurement and display system.

[0113] As Figure 1 shown, the irradiation supervision tube 1 is composed of a semi-groove shell 101 and an internal part 102. The inside of the irradiation supervision tube is filled with helium gas, and it is a sealed container product.

[0114] As Figure 2 shown, the high-pressure chamber 2 is composed of a cover 201, a tank body 202, a metal sealing ring 203, and bolt and nut connectors 204, and is used to support the workpiece 1 to be autoclaved and provide a high-temperature and high-pressure environment. The cover 201 of the high-pressure chamber has a medium channel 205, a temperature detection channel 206, and a pressure detection channel 207, which can realize the injection of helium gas medium or water medium into the high-pressure chamber and the measurement of the internal pressure and temperature of the high-pressure chamber. The tank body 202 of the high-pressure chamber has an exhaust hole 208, which can realize the discharge of air inside the high-pressure chamber. The high-pressure chamber cooperates with a control component, a pressure pump, and a pressure sensor to achieve a pressure of 25 MPa on the outer surface of the irradiation supervision tube.

[0115] As Figure 3 shown, the high-temperature chamber 3 is composed of a shell 301, a heat insulation layer 302, a heating element 303, etc., and is used to heat the high-pressure chamber. The high-temperature chamber cooperates with a control component and a temperature sensor to achieve a temperature environment of 300 °C for the irradiation supervision tube.

Through this device, the helium autoclaving of the irradiation supervision tube can be realized. The gas storage tank 1401 is a high-pressure helium gas cylinder. The gas pump 1501 is a high-pressure gas pump.

[0117] As shown in the Figure 4 figure, in the autoclaving device for the gas medium, the irradiation supervision tube 1 is installed in the high-pressure chamber 2, and then the high-pressure chamber 2 is installed in the high-temperature chamber 3. After connecting the equipment and circuits according to the figure, open the first stop valve 1301 and the second stop valve 1302, evacuate the air in the high-temperature chamber with helium, close the second stop valve 1302, and then fill the high-pressure chamber 2 with high-pressure helium. The control system first boosts the pressure and then raises the temperature through the control component, reaches a pressure of 25 MPa by controlling the gas pump 1501, controls the high-temperature chamber 3 to reach 300 °C and then automatically maintains the pressure and temperature. After reaching the required time, first reduce the pressure of the high-pressure chamber system to atmospheric pressure, then reduce the high-temperature chamber 3 to 100 °C and then open the high-temperature chamber 3. After the temperature in the high-pressure chamber 2 drops to 50 °C, open the high-pressure chamber 2 and take out the irradiation supervision tube 1 to complete the autoclaving of the irradiation supervision tube.

[0118] As Figure 5 shown in the figure, the autoclaving device for the liquid medium of the irradiation supervision tube includes an irradiation supervision tube 1, a high-pressure chamber 2, a high-temperature chamber 3, a temperature sensor 4, a temperature digital display 5, a safety valve 6, a first manual pressure relief valve 701, a third manual pressure relief valve 703, a pressure sensor 8, a pressure digital display 9, a control component 10, a third pressure gauge 1103, a second pipeline check valve 1202, a third stop valve 1303, a fourth stop valve 1304, a liquid storage tank 1402, a liquid pump 1502, a first liquid switch 1603, a second liquid switch 1604, a proportional valve 1702, a liquid pressure gauge 1802, a second pressure reducing valve 1902, and a second air filter regulator lubricator 2002. The water autoclaving of the irradiation supervision tube can be realized. The liquid storage tank 1402 is a pure water tank. The liquid pump 1502 is a high-pressure pump.

[0119] As Figure 5As shown in the figure, in the autoclaving device for liquid medium, the irradiation supervision tube 1 is installed in the high-pressure chamber 2, and then the high-pressure chamber 2 is installed in the high-temperature chamber 3. After connecting the equipment and lines according to the figure, open the third stop valve 1303 and the fourth stop valve 1304, and inject pure water as the liquid medium. At the same time, exhaust the gas inside the system completely. The control component controls the system to first increase the pressure and then increase the temperature. By controlling the liquid pump 1502, the pressure reaches 25 MPa, and by controlling the high-temperature chamber 3, the temperature reaches 300 °C and then automatically maintains the pressure and temperature. After reaching the required time, first reduce the pressure of the high-pressure chamber system to atmospheric pressure, then reduce the high-temperature chamber 3 to 100 °C and then open the high-temperature chamber 3. After the temperature inside the high-pressure chamber 2 drops to 50 °C, open the high-pressure chamber 2 and take out the irradiation supervision tube 1 to complete the autoclaving of the irradiation supervision tube.

[0120] The implementation method of the device in this embodiment is as follows:

[0121] 1) Before autoclaving, the measuring and displaying components such as temperature sensors, temperature digital displays, pressure sensors, pressure digital displays, and pressure gauges have been calibrated. The tube body of the irradiation supervision tube is in a state to be autoclaved. The autoclaving implementation site meets the requirements of safety production conditions.

[0122] 2) Open the cover of the high-pressure chamber and put in a group of irradiation supervision tubes. Use metal sealing rings and bolts and nuts to seal the high-pressure chamber, install the high-pressure chamber in the high-temperature chamber, and complete the assembly of the pressure sensor and temperature sensor inside the high-temperature chamber.

[0123] 3) When autoclaving with gas medium, after connecting the equipment and lines according to the gas medium autoclaving device diagram, open the helium gas cylinder pipeline and the high-pressure chamber stop valve, evacuate the air inside the high-temperature chamber with helium gas, close the high-pressure chamber stop valve, and then fill the high-pressure chamber with helium gas.

[0124] 4) When autoclaving with liquid medium, after connecting the equipment and lines according to the liquid medium autoclaving device diagram, close the high-pressure chamber stop valve, open the water tank pipeline stop valve, and inject water into the high-pressure chamber. After the high-pressure chamber is filled with water, use the manual pressure relief valve to exhaust the air inside the high-pressure chamber completely.

[0125] 5) The control component controls the high-pressure pump to increase the pressure of the medium in the high-pressure chamber. When the pressure reaches 25 MPa, turn on the heating function of the high-temperature chamber to make the external temperature of the high-pressure chamber reach 300 °C. After the inside of the high-pressure chamber reaches the specified high temperature and high pressure, start heat preservation and pressure maintenance. The above processes of pressure increase and temperature increase, heat preservation and pressure maintenance, and temperature compensation and pressure increase are automatically controlled by the integrated control system.

[0126] After the autoclaving operation reaches the specified time requirement, first reduce the system pressure to atmospheric pressure, then reduce the high-temperature chamber to 100 °C and then open the high-temperature chamber. After the temperature inside the high-pressure chamber drops to 50 °C, open the high-pressure chamber and take out the irradiation supervision tube to complete the autoclaving of the irradiation supervision tube.

The high-pressure gas pump is controlled to pressurize to 25 MPa, and the high-temperature chamber is controlled to be heated to 300 °C and then automatically keep pressure and temperature. After reaching the heat preservation and pressure maintenance time, first reduce the pressure of the high-pressure chamber system to atmospheric pressure, then reduce the high-temperature chamber to 100 °C and then open the high-temperature chamber. After the temperature in the high-pressure chamber drops to 50 °C, open the high-pressure chamber and take out the irradiation supervision tube to complete the "positive pressure" autoclaving of the helium medium of the irradiation supervision tube.

[0133] The said irradiation supervision tube is loaded into the high-pressure chamber and sealed through a metal sealing ring. The high-pressure chamber is loaded into the high-temperature chamber, and the equipment is connected according to the liquid medium autoclaving device diagram. The stop valve is opened, and pure water is injected into the high-pressure chamber to evacuate the air inside the high-pressure chamber. First, the pressure is increased and then the temperature is increased through the control component. The high-pressure liquid pump is controlled to pressurize to 25 MPa, and the high-temperature chamber is controlled to be heated to 300 °C and then automatically keep pressure and temperature. After reaching the heat preservation and pressure maintenance time, first reduce the pressure of the high-pressure chamber system to atmospheric pressure, then reduce the high-temperature chamber to 100 °C and then open the high-temperature chamber. After the temperature in the high-pressure chamber drops to 50 °C, open the high-pressure chamber and take out the irradiation supervision tube to complete the "positive pressure" autoclaving of the water medium of the irradiation supervision tube.
