Problems solved by technology

According to this process, on the one hand, due to the insulation structure on the outer wall of the autoclave, it takes a long time for the pressure and temperature in the autoclave to drop to a safe value. In addition, when the receiving container leaks, the angle valve cannot be closed in time.

Abstract

The invention belongs to the technical field of nuclear fuel cycling and particularly relates to a valve opening device for a uranium hexafluoride pressure heating tank. The valve opening device comprises a rotary box, a left connecting shaft, a cross shaft type universal coupling, a right connecting shaft, a magnetic coupling, a valve, an open valve disk, a spring and a cardan universal joint. Anoutput shaft of the rotary box is connected with the left connecting shaft, the cross shaft type universal coupling, the right connecting shaft, the magnetic coupling, the cardan universal joint andthe rotary box in sequence. The spring is arranged between the open valve disk and the cardan universal joint. The open valve disk is in centering connection with a valve rod of the valve. The valve opening device adopts the magnetic driving mode; the rotary box, the universal coupling, the universal joint, the spring and other parts are arranged on a transmission shaft. It is guaranteed that opening and closing of the angle valve on an internal storage container can be achieved without opening an end cover of the pressure heating tank.

Description

technical field [0001] The invention belongs to the technical field of nuclear fuel cycle, and in particular relates to a valve opening device for an autoclave of uranium hexafluoride. Background technique [0002] At present, in the field of uranium enrichment, the liquefaction and homogenization of UF6 is mainly realized by heating the concentrate in the receiving container through an autoclave. The autoclave is a closed pressure vessel. Functionally, on the one hand, it can realize the heating of the material receiving container, and at the same time, it can be used as an accident container of the material receiving container. Once the material receiving container leaks, it can be contained. In the previous process operation, after the heating is completed, when the pressure and temperature in the autoclave tank drop to a safe value, the end cover of the autoclave tank is opened, and then the angle valve on the receiving container is closed to complete the liquefaction of...
