[0020] like Figures 1 to 7As shown, a valve sealing combination safety gasket includes a cylindrical main body sealing combination column 1, and the main body sealing combination column 1 is made of stainless steel material and can be used instead of the existing single circular gasket. A full-through assembly combination connection hole 2 is provided at the center position of the main body sealing combination column 1, and this space can be used in conjunction with the delivery space of the pipeline when used. The interior of the assembly combination connection hole 2 is provided with an integrally formed and circumferentially evenly distributed arc-shaped first limiting matching plate 3 at the center position in the height direction, which can be used to match and connect the components of the valve delivery channel position matched at the upper end. The lower end of the assembly combination connection hole 2 is provided with a circumferentially distributed second assembly limiting column 4, which can ensure better structural strength on the inner side, and can perform a stable limiting combination of the embedded matching structure as needed, so that the combination accuracy during matching is higher and the matching stability is more reliable. The interior of the assembly combination connection hole 2 is located at the lower end of the first limiting matching plate 3 and is provided with a circle of second limiting matching plates 5, which can limit the matching components at the lower end position and enable a double-layer isolation space between the upper and lower matching components, thereby ensuring better matching stability during use, more convenient later maintenance, and no impact between different components. When in use, it can meet the insertion and combination of the ends of the pipe-type components that match at both ends through the two sets of limiting structures set up internally, and can play the role of stop fitting during assembly, with better position stability during installation. The internal arc-shaped limiting matching plate can cooperate with the rubber sealing ring for double sealing, which has better sealing stability during assembly and higher safety during later use. It can be reused during later maintenance, and has better structural stability, more reliable connection strength, and higher overall combination efficiency during assembly.

[0021] Preferably, the lower end position of the second assembly limiting column 4 coincides with the lower end surface of the main sealing combination column 1, so that the overall structural strength is better and the service life is longer during use.

[0022] Preferably, the thickness of the second position-limiting matching plate 5 is greater than that of the first position-limiting matching plate 3 , so that the bearing capacity of the lower end stop structure is stronger when matched, and the combination stability is more reliable.

[0023] Preferably, a spare assembly fastening connection thread groove is provided on the inner cylindrical surface of the assembly combination connection hole 2, and a fastening connection can be performed through the thread as needed, so that the matching stability during connection is more reliable.

[0024] Preferably, the upper and lower edge positions of the assembly combination connection hole 2 are provided with a convenient chamfer structure for installation and combination, which is more convenient when performing assembly and combination, has a matching guide function, and can improve the matching efficiency during assembly.

[0025] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or substitutions can be made without departing from the principles described in the present invention. These improvements or substitutions should also be regarded as the scope of protection of the present invention.
