[0023] See also Figures 1 to 4 , the utility model provides a technical solution:

[0024] Embodiment 1, a performance detection device for a sealing assembly for nuclear power equipment, the performance detection device for a sealing assembly for nuclear power equipment comprising: a gantry 1.

[0025] Specifically, a lifting device 2 is fixedly connected to one side of the gantry 1, and an upper pressure bin 3 is fixedly connected to one end of the lifting device 2. A supporting bin 4 corresponding to the position of the upper pressure bin 3 is arranged at the lower end of the upper pressure bin 3, and a sealing ring 15 is inserted at the upper end of the supporting bin 4, and the sealing ring 15 is located between the upper pressure bin 3 and the supporting bin 4. A white absorbent pad 6 is slidably inserted at the side of the gantry 1, and a valve No. 16 is fixedly connected to the upper end of the upper pressure bin 3, and a water inlet pipe 7 is fixedly connected to the upper end of the valve No. 16, and a water pumping device 8 is fixedly connected to one end of the water inlet pipe 7, and a valve No. 2 is fixedly connected to the lower end of the supporting bin 4, and a drain pipe 9 is fixedly connected to the lower end of the No. 2 valve 17, and a drain pipe 9 is fixedly connected to the upper end of the upper pressure bin 3. During the specific implementation, the lifting device 2 is first used to lift the upper pressure bin 3, and then the sealing ring 15 is inserted into the supporting bin 4, and then the upper pressure bin 3 is lowered onto the supporting bin 4, and the upper pressure is given by the lifting device 2 The upper pressure bin 3 is pressed tightly by the pressure bin 3, and then the white absorbent pad 6 is inserted into the side of the gantry 1, and the No. 1 valve 16 is opened. The water pumping device 8 then pumps water to the outside and injects it into the space between the upper pressure bin 3 and the supporting bin 4. The water injection is stopped after the injected water covers the gap between the upper pressure bin 3 and the supporting bin 4, and then the No. 1 valve 16 is closed. The water between the upper pressure bin 3 and the supporting bin 4 is pressurized by the booster pump 11. After the pressure is pressurized to the required pressure value, the pressurization is stopped, and the appropriate time is waited for. Then the white absorbent pad 6 is taken out, and the dryness and wetness of the white absorbent pad 6 is detected by the dryness and wetness detection device. If it becomes moister than before, it can be judged that the sealing performance of the sealing ring 15 cannot meet the requirements. Otherwise, it can be used. Then the No. 2 valve 17 is opened to let the water in the supporting bin 4 flow out through the drain pipe 9, and then the upper pressure bin 3 is raised and the sealing ring 15 is taken out to complete the detection. It is very convenient and less time-consuming.

[0026] In order to recycle water resources, one end of the drain pipe 9 of the present application is fixedly connected to a water tank 12, one side of the water tank 12 is fixedly connected to a flexible transmission pipe 10, the flexible transmission pipe 10 and the pumping device 8 are fixedly connected, and the side of the water tank 12 is fixedly connected to a pigment bin 13. The water output through the drain pipe 9 will enter the water tank 12, and the water drawn by the pumping device 8 is also stored in the water tank 12. The pigment bin 13 can inject soluble pigments into the water tank 12 to dye the water. In this way, if water flows out from the gap between the upper pressure bin 3 and the support bin 4, the place where the white absorbent pad 6 contacts the water will be dyed white, thereby more intuitively observing the test results of the sealing performance of the sealing ring 15.

[0027] In order to facilitate the insertion of the white absorbent pad 6, a placement rack 5 is fixedly connected to the side of the gantry 1 of the present application, and the white absorbent pad 6 and the placement rack 5 are slidably inserted, so that the white absorbent pad 6 can be better inserted into the gantry 1.

[0028] In order to facilitate the installation of the placement rack 5, the side of the placement rack 5 of the present application is fixedly connected with multiple connection blocks 14, and the multiple connection blocks 14 are all fixedly connected to the gantry 1, so that the placement rack 5 and the gantry 1 can be connected together.

[0029] In order to facilitate the insertion of the support bin 4, a placement groove 18 is opened at the upper end of the support bin 4 of the present application, and the sealing ring 15 and the placement groove 18 are slidably inserted, so that the sealing ring 15 can be placed between the gap between the upper pressure bin 3 and the support bin 4, so as to facilitate the detection of the sealing effect of the sealing ring 15.

[0030] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
