It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0030] The following describes the specific implementation of the present utility model in detail with reference to specific embodiments.

[0031] Please refer to Figures 1 to 5 , a low-temperature test device for a cryogenic regulating valve provided by an embodiment of the present utility model includes: a base 1, two cover plates 2 are installed on the upper surface of the base 1, a control device 3 is installed on one side of the base 1, a connecting pipe 4 is installed at one end of the base 1, auxiliary structures 5 are provided on both sides of the base 1, and opening and closing structures 6 are provided on both sides of the base 1.

[0032] In an embodiment of the present utility model, please refer to Figure 2 and Figure 3, the auxiliary structure 5 includes four fixing plates 501. The fixing plates 501 are fixedly connected to the base 1. A fixing rod 502 is fixedly connected to the upper surface of the fixing plate 501. The four fixing rods 502 are divided into two groups in pairs. A connecting plate 503 is fixedly connected to the upper ends of a group of fixing rods 502. An installation plate 504 is fixedly connected to one side of the two connecting plates 503 close to each other. Two fixing blocks 506 are fixedly connected to the upper surface of the installation plate 504. A servo motor 505 is fixedly connected to the upper surface of the fixing block 506. The output end of the servo motor 505 is fixedly connected to a turntable 507. A traction rope 508 is fixedly connected to the arc surface of the turntable 507. The lower end of the traction rope 508 is fixedly connected to an auxiliary block 509. Guide rails 510 are fixedly connected to both ends of the auxiliary block 509. A slide bar 513 is slidably connected to the inner wall of the guide rail 510. A spring 511 is arranged inside the guide rail 510. The two ends of the spring 511 are fixedly connected to the slide bar 513 and the guide rail 510 respectively. When it is necessary to detect the valve, move the sides of the two slide bars 513 away from each other. The slide bar 513 slides on the inner wall of the guide rail 510, and the slide bar 513 drives the spring 511 to contract. Then place the valve between the two slide bars 513, and then release the two slide bars 513. The spring 511 stretches to drive the slide bar 513 to clamp and fix the valve. Moreover, an included angle is formed between the two slide bars 513 and the horizontal plane, so that the heavier the object, the greater the clamping force. The fixing block 506 is fixedly connected to the fixing plate 501 through two bolts. A limiting rod 512 is fixedly connected to the inside of the guide rail 510. The limiting rod 512 is slidably connected to the slide bar 513. The spring 511 is sleeved on the arc surface of the limiting rod 512. The limiting rod 512 can limit the spring 511 to prevent the spring 511 from deforming during use, and improve the service life of the spring 511. A number of notches 514 are opened on one side of the two slide bars 513 close to each other. The number of notches 514 is evenly distributed on the slide bar 513. The notches 514 can increase the friction force between the slide bar 513 and the connected object, and prevent the slide bar 513 from sliding when clamping and fixing the valve;

[0033] In an embodiment of the present invention, please refer to Figure 4 and Figure 5, the opening and closing structure 6 includes a slide rail 61. The slide rail 61 is fixedly connected to the base 1. Two sliders 67 are slidably connected to the inner wall of the slide rail 61. Chutes 62 are formed on both sides of the cover plate 2. A moving block 63 is slidably connected to the inner wall of the chute 62. A rotating shaft 65 is fixedly connected to the side of the moving block 63 away from the chute 62. A long plate 66 is rotatably connected to the arc surface of the rotating shaft 65. The long plate 66 is fixedly connected to the slider 67. When the cover plate 2 needs to be opened, the long plate 66 is pulled to move. The long plate 66 drives the two sliders 67 to move away from each other. Then the sliders 67 slide on the inner wall of the slide rail 61. The long plate 66 rotates on the arc surface of the rotating shaft 65. The rotating shaft 65 drives the moving block 63 to move. The moving block 63 slides on the inner wall of the chute 62. When the moving block 63 slides on the inner wall of the chute 62, it drives the cover plate 2 to move. When the cover plate 2 needs to be closed, the long plate 66 is pulled to drive the two sliders 67 to move closer to each other. A handle rod 64 is fixedly connected to the side of the long plate 66 away from the slide rail 61. A plurality of anti-slip grooves 62 are formed on the arc surface of the handle rod 64. When the long plate 66 needs to be pulled, the handle rod 64 can be directly pulled. The anti-slip lines can increase the friction between the hand and the handle rod 64. A slide bar 68 is fixedly connected to the inside of the slide rail 61. The slide bar 68 is slidably connected to the slider 67. The slide bar 68 can limit the slider 67 to prevent the slider 67 from shifting when sliding on the inner wall of the slide rail 61;

[0034] The working principle of a low-temperature test device for a cryogenic control valve provided by the present utility model is as follows: When the valve needs to be detected, the sides of the two slide bars 513 away from each other are moved. The slide bars 513 slide on the inner wall of the guide rail 510. The slide bars 513 drive the springs 511 to contract. Then the valve is placed between the two slide bars 513. Then the two slide bars 513 are released, and the springs 511 stretch to drive the slide bars 513 to clamp and fix the valve. Moreover, both of the two slide bars 513 form an angle with the horizontal plane, so that the heavier the object, the greater the clamping force. The limiting rod 512 can limit the springs 511 to prevent the springs 511 from deforming during use, and improves the service life of the springs 511. The notch 514 can increase the friction between the slide bars 513 and the connected object, and prevent the slide bars 513 from sliding when clamping and fixing the valve.

[0035] When it is necessary to open the cover plate 2, the long plate 66 is pulled to move. The long plate 66 drives the two sliders 67 to move away from each other. Then the sliders 67 slide on the inner wall of the slide rail 61, and the long plate 66 rotates on the arc surface of the rotating shaft 65. The rotating shaft 65 drives the moving block 63 to move, and the moving block 63 slides on the inner wall of the chute 62. When the moving block 63 slides on the inner wall of the chute 62, it drives the cover plate 2 to move. When it is necessary to close the cover plate 2, the long plate 66 is pulled to drive the two sliders 67 to move closer to each other. When it is necessary to pull the long plate 66, the handle 64 can be directly pulled. The anti-slip pattern can increase the friction between the hand and the handle 64. The slide bar 68 can limit the sliders 67 to prevent the sliders 67 from shifting when sliding on the inner wall of the slide rail 61.
