One-hole multi-point cabin penetrating sealing device and method for temperature and pressure measuring probe

Abstract

The invention belongs to the technical field of pipeline cabin penetrating sealing, and discloses a one-hole multi-point cabin penetrating sealing device and method for a temperature and pressure measuring probe. The one-hole multi-point cabin penetrating sealing device for the temperature and pressure measuring probe is provided with a high-pressure cabin body, wherein the middle of the upper endof the high-pressure cabin body is provided with an open slot, the upper end of the high-pressure cabin body is sleeved with a sealing base, and the upper end of the sealing base is fixed with a sealing gland through a locking bolt; a plurality of through holes, which are aligned up and down, are formed between the sealing base and the sealing gland, and the through holes are arranged in a concentric ring shape; cylindrical compression columns are arranged at the positions of the through holes at the junction of the sealing base and the sealing gland, the lower end of each compression columnis provided with a conical sealing clamping sleeve, and a hole communicated with the through hole is formed between each compression column and the corresponding sealing clamping sleeve. The device isgood in universality, can be easily installed on different high-pressure equipment through an O-shaped ring seal, can carry out high-temperature and low-temperature resistant seal expansion, and effectively expands deep research of stratum and deep water area research of ocean engineering.

Description

technical field [0001] The invention belongs to the technical field of pipeline penetration sealing, and in particular relates to a one-hole multi-point penetration sealing device and method for temperature and pressure measuring probes. Background technique [0002] At present, the closest existing technology: At present, with regard to the pipeline piercing technology of hyperbaric chambers, most of them realize the sealing and piercing technology of high pressure chambers by compressing and sealing a single or a small number of pipelines. The sealing structure of dense pipelines, most of the current physical models can reach up to 5-6 at most in one hole and multiple points, which is far from satisfying the structure of a large number of high-density pipelines through the warehouse. This invention proposes a method of sealing 90 pipelines in one hole The special structure of the pipeline realizes that the limited space can carry high-density sealed pipelines, and has achi...

AI Technical Summary

Problems solved by technology

[0006] When multiple or multiple pipelines pass through the high-pressure cabin as a whole, most of them are sealed through a one-hole multi-line sealing joint, which is prone to stress concentration and other phenomena. Due to the brittleness of the seal, cracks or micro-cracks appear, resulting in seal failure. and leakage, it will lead to the loss of equipment function, and seriously cause the damage of the whole set of equipment
