Cabin-penetrating sealing device and operation method

Abstract

The invention relates to a cabin-penetrating sealing device. The cabin-penetrating sealing device comprises the following components of a cabin body, a sealing base and a sealing gland, wherein a cabin body groove is formed in the cabin body; the sealing base is fixedly arranged at the position close to a notch of the cabin body groove in a sleeving mode so as to seal the cabin body groove, and aplurality of first through holes penetrating through a body of the sealing base are formed in the sealing base; the sealing gland is arranged at the upper end of the sealing base, and a plurality of second through holes which penetrate through a body of the sealing gland and are formed in one-to-one correspondence with the plurality of first through holes are formed in the sealing gland; and the first through holes and the corresponding second through holes jointly form cabin penetrating holes allowing cabin penetrating pieces to penetrate into the cabin body groove. The cabin-penetrating sealing device adopts a simple clamping sleeve and pressing cap structure, the function of unified and centralized sealing of the plurality of pipelines is achieved, the function of cabin penetrating of the plurality of pipelines of a pressure vessel is achieved, and the blank of a dense cabin penetrating structure of a plurality of pipelines of a related hyperbaric cabin is filled up.

Problems solved by technology

[0002] In the field of hydrate development and exploitation, some low-temperature and high-pressure simulation equipment are often used, especially related experimental equipment for simulating deep formations and hydrate mining simulation research equipment. When the experimental simulation equipment or practical application equipment needs to carry out many When pipelines and thermocouples are sealed and multi-channel centralized penetrating tanks are sealed, multiple or multiple pipelines are required to be brought together to pass through the high-pressure cabin (end cover) as a whole. At present, the implementation of such technologies in the field of hydrate experiments is Most of the pipes or metal probes are poured or embedded in a high-strength ceramic or glass block as a whole, but when a certain pressure is reached, due to the brittleness of ceramics and glass, stress concentration is often prone to occur, resulting in a Due to the brittleness and hardness of the seal, cracks or micro-cracks appear in the multi-hole sealing joint, resulting in seal failure and leakage, which will lead to the loss of equipment function and seriously damage the entire set of equipment.

At present, there is no corresponding solution. The above pouring structure is unstable, and it is easy to break and fail when switching between high pressure and low pressure

[0003] On the other hand, when it is necessary to arrange many probes, the probes pass through the hatch cover from the model, and the hyperbaric cabin pipeline piercing technology is required, and most of them realize the high pressure cabin seal piercing through a single or a small number of pipelines. Technology, large volume, insufficient density, it is difficult to meet the sealing structure of a large number of high-density pipelines. At present, most physical models can have a maximum of 5-6 points per hole, which is far from satisfying a large number of high-density pipelines. Penetration structure
