[0021] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. Apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model. Embodiment

[0022] Please refer to Figures 1-4 A kind of anti-shock stop valve structure, including damping box 1 and valve body 2, valve body 2 is installed on buffer box 3, buffer box 3 inside two adjacent inner walls are respectively fixedly installed with sliding rod one 11 and sliding rod two 12, sliding block 15 is slidably installed on sliding rod one 11 and sliding rod two 12, the sliding block 15 between two corresponding sliding rod one 11 on damping box 1 is connected by guide rod one 14, the sliding block 15 between two corresponding sliding rod two 12 is connected by guide rod two 13, two adjacent outer walls of buffer box 3 are respectively fixedly installed with connecting arm one 31 and connecting arm two 32, buffer box 3 is slidably installed on guide rod one 14 by connecting arm one 31, while buffer box 3 is slidably installed on guide rod two 13 by connecting arm two 32, hanging ring 34 is fixedly installed on the inner chamber top of buffer box 3, hanging ring 34 is hung with swing arm 36, counterweight ball 37 is fixedly arranged at the end of swing arm 36;

[0023] The slide bar one 11 and the slide bar two 12 are perpendicular to each other and staggered vertically on the two inner walls inside the buffer box 3, the slide bar one 11 is parallel to the guide rod two 13, and the slide bar two 12 is parallel to the guide rod one 14.

[0024] Specifically, the slide block 15 is slidably installed on the slide bar one 11 and the slide bar two 12, the slide block 15 on the corresponding slide bar in the damping box 1 is connected through the guide rod one 14 and the guide rod two 13 respectively, the buffer box 3 is slidably installed on the guide rod one 14 through the connecting arm one 31 and slidably installed on the guide rod two 13 through the connecting arm two 32, when the vibration occurs, the buffer box 3 can slide on the guide rod through the connecting arm, and the slide block 15 also slides on the slide bar;

[0025] Inside the buffer box 3, the swing arm 36 hung on the hanging ring 34 and the counterweight ball 37 at the end will swing when the vibration occurs. The counterweight ball 37 has a large mass, and its inertia will keep it relatively stable when the vibration occurs, while the swing of the swing arm 36 will be affected by the vibration. In this way, the swing of the swing arm 36 and the counterweight ball 37 will interact with the vibration of the buffer box 3, change the direction and frequency of the vibration, and the inertia of the counterweight ball 37 will also offset a part of the vibration energy, further reducing the vibration of the buffer box 3 and the valve body 2 and other components connected thereto, achieving a more comprehensive and detailed damping effect;

[0026] Through the cooperative action of the slide block 15, the guide rod and the swing arm 36 and the counterweight ball 37, the vibration can be buffered and absorbed from multiple dimensions, effectively reducing the influence of the vibration on the stop valve, reducing the risk of valve damage caused by vibration, improving the anti-vibration performance of the valve, and ensuring the normal work of the valve in the vibration environment.

[0027] Further, in order to further improve the damping effect, please refer to Figures 1-4 The guide rod one 14 and the guide rod two 13 are both sleeved with springs 16, the connecting arm one 31 is connected with the slide block 15 on the slide bar one 11 through the spring 16, and the connecting arm two 32 is connected with another slide block 15 on the slide bar two 12 through another spring 16.

[0028] The top of the buffer box 3 is provided with a vertical damping assembly 33, the buffer box 3 is connected with the mounting plate 35 through the damping assembly 33, and the mounting plate 35 moves up and down on the top of the buffer box 3 through the damping assembly 33.

[0029] The valve body 2 is installed on the mounting plate 35 through bolts.

[0030] Specifically, when the vibration occurs, the spring 16 will be compressed or stretched during the sliding process of the sliding block 15 on the slide rod and the sliding process of the buffer box 3 on the guide rod through the connecting arm. The elastic deformation of the spring 16 can absorb and store part of the vibration energy, convert the kinetic energy of the vibration into the elastic potential energy of the spring 16, and then release the elastic potential energy when the vibration is weakened, thereby reducing the direct impact of the vibration on the stop valve;

[0031] The spring 16 will generate an elastic restoring force after deformation, which can make the sliding block 15 and the buffer box 3 return to the equilibrium position after the vibration and continuously play a buffering role in subsequent vibrations. Meanwhile, the elasticity of the spring 16 enables the buffer box 3 to adapt to the changes of the vibration through the stretching and contraction of the spring 16 under the vibration in different directions, further enhancing the buffering capacity of the vibration;

[0032] The vertical buffering assembly 33 arranged at the top of the buffer box 3 is connected with the buffer box 3 and the mounting plate 35, and the valve body 2 is mounted on the mounting plate 35. When there is a vertical vibration, the mounting plate 35 can move up and down on the top of the buffer box 3 through the vertical buffering assembly 33, and the vertical buffering assembly 33 can provide an additional buffering space for the valve body 2 in the vertical direction, absorb and disperse the vertical vibration energy, and reduce the influence of the vertical vibration on the valve body 2;

[0033] The combination of the multiple buffering mechanisms processes the vibration from multiple dimensions, effectively reduces the influence of the vibration on the stop valve, greatly improves the anti-vibration performance of the valve, and enables the stop valve to remain in a normal working state in a relatively severe vibration environment, reduces the probability of problems such as valve damage and seal failure caused by the vibration, prolongs the service life of the valve, and ensures the safe and stable operation of the entire system.
