Problems solved by technology
[0002] For the sealing of the ultra-high pressure globe valve, in the prior art, various sealing rings and gaskets are mostly used for sealing. When the pressure in the cavity is particularly high, the sealing effect is not good, and it is easy to cause pressure relief and accidents. Therefore, it is necessary to design an ultra-high pressure globe valve structure that can adapt to the sealing requirements under various pressures.

The invention belongs to the technical field of stop valves and particularly relates to an ultra-high-pressure stop valve. The ultra-high-pressure stop valve comprises a valve body. A high-pressure pipeline is arranged at the middle portion of the valve body. A valve element is arranged in the valve body. Sealing assemblies are embedded in the valve element. The sealing assemblies comprise sealingassemblies I and sealing assemblies II, and the valve element is connected with an air cylinder assembly through a valve rod. The sealing assembly I and the sealing assembly II are cylindrical. Passages I and passages II are arranged in the middles of the sealing assemblies I and the middles of the sealing assemblies II correspondingly, the two sealing assemblies I and the two sealing assembliesII are arranged, the two sealing assemblies I are separated through the valve element, and the two sealing assemblies II communicate with each other through the passages II. By means of the ultra-high-pressure stop valve, due to the passages in the sealing assemblies, ultra-high-pressure fluid is led into a sealing ring, pressure of the ultra-high-pressure fluid is used for pressing the sealing ring to a combination face, the stop valve is not likely to release pressure when the pressure in a cavity is high, and the sealing performance is good. The ultra-high-pressure stop valve is used for stop sealing of liquid in a high-pressure environment.
Description
technical field [0001] The invention belongs to the technical field of cut-off valves, in particular to an ultra-high pressure cut-off valve. Background technique [0002] For the sealing of the ultra-high pressure globe valve, in the prior art, various sealing rings and gaskets are mostly used for sealing. When the pressure in the cavity is particularly high, the sealing effect is not good, and it is easy to cause pressure relief and accidents. Therefore, it is necessary to design an ultra-high pressure stop valve structure that can adapt to the sealing requirements under various pressures. Contents of the invention [0003] In view of the above technical problems, an ultra-high pressure cut-off valve with good sealing and not easy to release pressure is provided. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] An ultra-high pressure cut-off valve, comprising a valve body, ...
