[0023] The present invention will be further described below with reference to the embodiments.

[0024] Please see Figures 1-5 This utility model provides a novel cryogenic manifold valve assembly for cutting gas, including a cryogenic valve 1, a pipe 2, a support mechanism 3, and a buffer mechanism 4. The cryogenic valve 1 is connected to both sides of the pipe 2, the support mechanism 3 is located below the cryogenic valve 1, and the buffer mechanism 4 is located below the support mechanism 3.

[0025] The support mechanism 3 consists of a support base 301, a telescopic rod 302, a fixed rod 303, a rack 304, a movable plate 306, a positioning block 307, a connecting rod 308, a baffle 309, and a first spring 310. The support base 301 is fixedly connected to the lower part of the cryogenic valve 1, the telescopic rod 302 is fixedly connected to the lower part of the support base 301, the fixed rod 303 is located outside the telescopic rod 302, and the telescopic rod 302 slides inside the fixed rod 303. The rack 304 is fixedly connected to the left side of the telescopic rod 302. An installation groove 305 is provided in the upper left of the interior of the fixed rod 303. The movable plate 306 is slidably connected to the interior of the installation groove 305. The positioning blocks 307 are evenly fixedly connected to the right side of the movable plate 306.

[0026] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the size of the tooth block on the rack 304 is the same as that of the positioning block 307, and the inclined surface of the tooth block on the rack 304 is opposite to the inclined surface of the positioning block 307.

[0027] The rack 304 and the positioning block 307, which are set in opposite directions, can be moved in one direction, making it easy to pull out the telescopic rod 302.

[0028] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the connecting rod 308 is fixedly connected to the left side of the movable plate 306, and the connecting rod 308 is slidably connected between the mounting groove 305 and the outer surface of the fixed rod 303. The baffle 309 is fixedly connected to the left end of the connecting rod 308, and a handle is provided on the left side of the baffle 309.

[0029] When it is necessary to retract the length of the telescopic rod 302, manually pull the handle. The baffle 309 drives the moving plate 306 to move to the left. The moving plate 306 drives the positioning block 307 to retract into the mounting slot 305, releasing the restriction on the rack 304. At this time, the telescopic rod 302 can be slid into the fixed rod 303 for easy storage.

[0030] As can be seen from the above working process, the extension length of the telescopic rod 302 can be adjusted by the support mechanism 3, so as to adapt to the installation of cryogenic valve 1 at different heights, improve the applicability and flexibility of the mechanism, improve the stability of cryogenic valve 1 during use, and ensure the normal operation of the valve group.

[0031] Further as Figure 2 , Figure 3 and Figure 5As shown, it is worth noting that the first spring 310 is symmetrically arranged on the front and rear sides of the connecting rod 308, and the first spring 310 is fixedly connected between the moving plate 306 and the side of the mounting groove 305.

[0032] The first spring 310 can both reset the positioning block 307 and fix the position of the rack 304 by its own elasticity, and ensure that the moving plate 306 has room to move so that it can be used in the future.

[0033] Further as Figure 2 , Figure 3 and Figure 5 As shown, it is worth noting that the buffer mechanism 4 consists of a base plate 401, a fixed column 402, a movable column 403, a second spring 404, a base 405, a connecting plate 406, a rotating shaft 407, a rotating rod 408, a slider 409, and a third spring 410. The base plate 401 is fixedly connected to the bottom of the fixed rod 303. The fixed column 402 is symmetrically fixedly connected to the bottom of the base plate 401. The movable column 403 is slidably connected to the bottom surface of the fixed column 402. The second spring 404 is fixedly connected between the movable column 403 and the fixed column 402. The base 405 is fixedly connected to the bottom of the movable column 403.

[0034] Further as Figure 2 , Figure 3 and Figure 5 As shown, it is worth noting that the connecting plate 406 is fixedly connected between the two fixed columns 402, the rotating shaft 407 is inside the connecting plate 406, the rotating rod 408 is symmetrically rotated and connected to the outside of the rotating shaft 407, the slider 409 is fixedly connected to the other end of the rotating rod 408, one end of the base 405 is provided with a groove that matches the slider 409, and the third spring 410 is fixedly connected between the slider 409 and the groove.

[0035] This solution has the following working process: During installation and use, the cryogenic valve 1 is first connected to the pipe 2 via a flange. Then, the fixing rod 303 is pulled down, causing the positioning block 307 and the rack 304 to move in opposite directions. The rack 304 squeezes the positioning block 307, causing it to retract into the mounting groove 305, thus avoiding obstructing the movement of the fixing rod 303, until the buffer mechanism 4 below contacts the ground. At the same time, the moving plate 306 is reset under the elastic action of the first spring 310, causing the positioning block 307 to re-insert into the rack 304, fixing the height of the telescopic rod 302, providing support for the cryogenic valve 1, and ensuring the stability of the cryogenic valve 1 during use.

[0036] When the cryogenic valve 1 is subjected to external vibration, the vibration is transmitted to the fixed rod 303 through the support base 301 and the telescopic rod 302. The vibration continues to be transmitted to the buffer mechanism 4 below through the fixed rod 303. In the buffer mechanism 4, the base plate 401 is vibrated first, and then the vibration is transmitted to the moving column 403 through the fixed column 402. Since a second spring 404 is provided between the moving column 403 and the fixed column 402, the second spring 404 absorbs and disperses some of the vibration energy, playing a buffering role. At the same time, the vibration is transmitted to the slider 409, causing the slider 409 to slide inside the slide groove, driving the rotating rod 408 to rotate outside the rotating shaft 407. Since a third spring 410 is provided between the slider 409 and the slide groove, the third spring 410 further absorbs and disperses the vibration energy, enhancing the buffering effect and improving the stability of the connection at both ends of the cryogenic valve 1.

[0037] In summary: the support mechanism 3 allows for adjustment of the extension length of the telescopic rod 302, thus adapting to the installation of cryogenic valves 1 at different heights, improving the applicability and flexibility of the mechanism, enhancing the stability of cryogenic valves 1 during use, and ensuring the normal operation of the valve assembly; the buffer mechanism 4 absorbs and dissipates vibration energy during the use of cryogenic valves 1, thereby reducing vibration and ensuring the stability and safety of the connection of cryogenic valves 1.
