A multi-line lead-out device for a high-pressure vessel

Abstract

The invention discloses a multi-wire lead-out device of a high-pressure container. A first lead, a second lead and a third lead are inserted into a hole in the middle of a T-shaped wire-leading bolt. Gaps between the first lead and the hole, between the second lead and the hole and between the third lead and the hole are filled by pouring flexible sealing resin and rigid sealant in a layered mode. The T-shaped wire-leading bolt is inserted into a metal shell of the high-pressure container. The bottom of the T-shaped wire-leading bolt is provided with a nut for connection. A first O-shaped ring and a second O-shaped ring are arranged between the T-shaped wire-leading bolt and the metal shell of the high-pressure container, and therefore gaps between the T-shaped wire-leading bolt and the metal shell of the high-pressure container are sealed. The leads are inserted into the hole in the middle of the T-shaped wire-leading bolt and the flexible sealing resin and the rigidity sealant are used for sealing. The device is novel in structure, convenient to machine, low in cost and high in applicability and has certain business popularization value.

Description

technical field [0001] The invention relates to the field of pressure vessel sealing in mechanical engineering, and more particularly relates to a multi-wire lead-out device for airtight vessels under high pressure conditions. It is suitable for non-standard lead wires (such as multiple wires passing through at the same time, uneven thickness of a single lead wire tested successively, and no plastic package outside the lead wire), frequent disassembly and replacement (such as successive inspections in scientific experiments) and other situations. Background technique [0002] In the field of material testing and mechanical processing, multiple sensors (such as pressure, temperature, deformation, and acoustic signals) are often used to observe the specimen in the airtight container. The sensors inside the high-pressure container need to be drawn out through wires and transmitted to the external data acquisition system. . How to reliably and reasonably lead out multiple wires...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the above-mentioned technical problem of multiple wires leading out of the high-pressure container, the existing technical solutions on the market have defects in varying degrees: 1) The common porous lead device is connected to the airtight container from the outside through threads or snap rings, although it is easy to process, Inexpensive, but with serious security risks

But the problem is that the lead body and the outside of the metal shell are fixed by two bolts. The design of this structure has limited pressure bearing capacity, and there is still a safety hazard that the bolt elements pop out at high speed.
