Problems solved by technology

[0003] However, due to the differences in material and manufacturing process of the supervisory tube, the test results will be affected. In order to eliminate the influence of the supervisory tube itself, an online detection test device for the irradiation supervisory tube is needed. Since the kettle body is mainly subjected to high temperature and high pressure , and the lid of the kettle needs to open multiple through holes to control the filling and discharging of gas and the input of data lines and control lines in addition t

Embodiment 1

[0041] Such as figure 1 , figure 2 As shown, the present invention is a temperature-compensated kettle lid of a radiation supervisory tube test device, the temperature-compensated kettle lid includes a kettle lid 20 and a plurality of first compensation temperature sensors 22 arranged on the kettle lid 20, the kettle lid At least three first compensation temperature sensors 22 are evenly arranged on the outside of the circumferential surface of the cover 20, and a first compensation temperature sensor 22 is arranged at the middle position outside the kettle cover 20; the above-mentioned first compensation temperature sensors 22 are respectively connected to an external automatic control system, Real-time test the temperature of each first compensation temperature sensor 22;

[0042] The temperature compensation kettle cover is used to connect with the kettle body 19 that cooperates with it. When the difference between the average value of each of the first compensation tempe...

Embodiment 2

[0051] Such as figure 1 , figure 2 As shown, the difference between this embodiment and Example 1 is that a temperature compensation kettle of a radiation supervision tube test device includes a kettle body 19, a temperature compensation plate 21 and a radiation supervision tube described in Example 1. The temperature compensation kettle cover of the test device, the temperature compensation plate 21 is arranged between the inner side of the kettle cover 20 and the kettle body 19; the kettle body 19 is a cylindrical chamber placed horizontally, one side of the kettle body 19 is closed, and the other side is closed. The side opening, the kettle cover 20 is snapped on the opening side of the kettle body 19, so that the kettle cover 20 is sealed and connected with the kettle body 19;

[0052] The inner wall of the kettle body 19 is provided with a second compensating temperature sensor 25 near the kettle cover 20; in the described kettle body 19, several temperature sensors 13 ...

Embodiment 3

[0064] Such as figure 1 , figure 2 As shown, the difference between this embodiment and embodiment 1 is that, specifically as figure 2 As shown, a kind of radiation supervisory tube test device comprises a high-temperature autoclave, a fixing device 12, a vacuum device, a booster device, a heating device and an automatic control system, and the vacuum device and the booster device are all connected to the high-temperature autoclave; The vacuum device, booster device and heating device are all connected with the automatic control system;

[0065] The high-temperature autoclave includes a kettle body 19 and a kettle cover 20. The kettle body 19 is a cylindrical chamber placed horizontally. One side of the kettle body 19 is open and the other side is closed. The kettle body 20 is connected to the kettle body. 19 opening to form a closed space; the irradiation supervision tube 11 is sent into the kettle body 19 from the opening of the kettle body 19, and is installed inside th...

Abstract

The invention discloses a temperature compensation kettle cover and a temperature compensation kettle of an irradiation monitoring pipe test device. The temperature compensation kettle comprises a kettle body, a temperature compensation plate and a temperature compensation kettle cover, the temperature compensation kettle cover comprises a kettle cover and a plurality of compensation temperature sensors arranged on the kettle cover, at least three compensation temperature sensors are uniformly arranged on the outer side of the circumferential surface of the kettle cover, and one compensation temperature sensor is arranged in the middle of the outer side of the kettle cover. Each compensation temperature sensor is connected to an external automatic control system, and the temperature of each compensation temperature sensor is tested in real time. The temperature compensation kettle cover is used for being connected with a kettle body matched with the temperature compensation kettle cover for use, and when the difference value between the mean value of all the compensation temperature sensors and the external reference temperature exceeds a set threshold value, the external automaticcontrol system conducts heating by controlling the temperature compensation plate between the kettle cover and the kettle body to compensate the temperature of the kettle cover. According to the invention, temperature loss can be effectively prevented, and the temperature in the cavity is kept accurate and uniform.

Description

technical field [0001] The invention belongs to the field of electric power, in particular to the field of nuclear power, in particular to a temperature compensation kettle cover and a temperature compensation kettle of a radiation supervision tube test device in the field of nuclear power. Background technique [0002] Due to the long-term radiation of the pressure vessel in the nuclear power plant, the performance or structure of the pressure vessel will change, which is not conducive to the safe operation of the nuclear power plant. Therefore, it is necessary to carry out long-term continuous monitoring of the pressure vessel. The radiation supervision tube is made of the base metal and weld material of the pressure vessel, and is taken out as planned for performance testing and analysis during the reactor life, so as to monitor and predict the performance change of the pressure vessel material after irradiation. [0003] However, due to the differences in material and ma...
