AI Technical Summary

Technical Problem

The existing wall-through system has poor sealing effect, which can easily lead to the migration of pollutants between high-level clean areas and low-level clean areas, causing pollution to high-level clean areas.

Method used

A wall-through system is adopted that includes a sleeve with a hollow structure and an elastic seal with an annular structure. The elastic seal sleeve is arranged on the outer peripheral surface of the sleeve. The inner seal circumference surface forms a continuous circumferential seal with the cylinder wall. The reinforcement part increases the axial thickness and circumferential sealing effect of the elastic seal.

Benefits of technology

Complete sealing between the sleeve and the independent area is achieved, pollutant migration is avoided, and sealing performance and cleanliness of the wall-through system are improved.

Abstract

The utility model discloses a through-wall system, which is characterized in that a connecting channel and a sleeve are sealed by sleeving an elastic sealing piece on the sleeve, so that two independent areas are prevented from being directly communicated through a gap between the connecting channel and the sleeve, and the pollution to the independent areas is avoided. According to the reinforcing part of the elastic sealing element, on one hand, the axial thickness of the elastic sealing element is increased through the reinforcing part, the structural strength of the elastic sealing element is improved, when the elastic sealing element is arranged on the cylinder wall in a sleeving mode, circumferential tensioning force can be formed on the elastic sealing element, and the elastic sealing element is prevented from being twisted or torn due to pulling stress; the inner edge of the reinforcing part and the outer circumferential face of the sleeve wall form continuous circumferential sealing, the reinforcing part is matched with the inner sealing circumferential face to achieve circumferential complete sealing of the gap between the communicating channel and the sleeve, the sealing area is larger, and the sealing effect is better.
