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 cut-off valves, and specifically relates to an ultra-high pressure cut-off valve, which includes a valve body, a high-pressure pipeline is arranged in the middle of the valve body, a valve core is arranged inside the valve body, and the valve core is embedded with a There is a sealing assembly, and the sealing assembly includes sealing assembly I and sealing assembly II, and the valve core is connected with a cylinder assembly through a valve rod. Both the sealing assembly I and the sealing assembly II are cylindrical. The middle parts of the sealing assembly I and the sealing assembly II are respectively provided with a passage I and a passage II. There are two sealing components I and two sealing components II, the two sealing components I are separated by the valve core, and the two sealing components II are connected by the passage II. The invention passes the ultrahigh pressure fluid into the sealing ring through the passage in the sealing assembly, and uses the pressure of the ultrahigh pressure fluid to press the sealing ring to the joint surface, so that the shut-off valve is not easy to release pressure and has good sealing performance when the pressure in the cavity is high. The invention is used for the cut-off sealing of liquid under 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, ...
