Universal Double Cover Hot Cell Service Airlock

Abstract

The invention belongs to the field of chamber design of the nuclear industry, and in particular relates to a general double-cover type hot cell maintenance airlock. The purpose is to provide a general-purpose double-cover type hot cell maintenance airlock that can be commonly used in different hot cells. The airlock body is a sealed chamber made of stainless acid-resistant steel plates. There are two independent partitions in the inner temperature zone and the hot zone. The independent zones are connected through a sealed door; the temperature zone is also equipped with a sealed door and a hot room outside the airlock for maintenance. The area is connected; the hot area is additionally provided with a sealed door to connect with the hot chamber; the hot area of ​​the airlock body and the hot chamber are provided with a double-covered airtight door, and the double-covered airtight door is sealed by a double cover installed in the hot area of ​​the airlock body. It consists of an outer door and a double-cover sealed inner door installed on the heat chamber shell. The advantages are high strength and good sealing performance; it eliminates the need to repeatedly build an air tent, realizes fast docking and disengagement, and the interface surface is not contaminated after separation, and it also has the advantages of convenient transfer.
