Novel air-tight door with linkage synchronous lock

Abstract

The invention discloses a novel air-tight door with linkage synchronous lock, and is characterized in that a driving mechanism comprises a drive gear and a driven gear, which are engaged; a linkage mechanism comprises a connecting rod A and a combined connecting rod, and the combined connecting rod comprises a connecting rod B coaxially fixed by an axial adjustment component; each of insertion locking mechanisms comprises a pin shaft, a locking pin and a slope wedge block, and the pin shaft is inserted in a pinhole on the locking pin; the driven gear is hinged with the connecting rod A, the connecting rod A is hinged with the combined connecting rod, the connecting rod B is hinged with the locking pin, the pin shaft is fixed on a door leaf, and the slope wedge block is fixed on a door frame; when the sealing door is locked, the locking pin is inserted into the slope wedge block. According to the sealing door provided by the invention, when the sealing door is closed, the driving gear can control multiple insertion locking mechanisms to lock the fan leaf synchronously, so that the integrated compaction quantity of sealing materials of the sealing door is balanced and consistent on a vertical surface, and the reliable sealing effect of the sealing door under a nuclear radiation environment is achieved; meanwhile, a purification plant of a nuclear power plant reaches using requirements without nuclear leakage under a shock resistant condition.

Description

technical field [0001] The invention relates to the hermetic door technology, in particular to a novel hermetic door suitable for interlocking synchronous locking in nuclear power plants. Background technique [0002] The airtight door of the nuclear power plant is the entrance and exit for personnel to enter and exit the purification device. Its strength is required to be able to maintain a good seal under the SSE earthquake load, and the working pressure is negative pressure, which belongs to the equipment used in the radiation environment. In order to achieve the safety of operators and the protection of the environment, the airtight doors of nuclear power plants must be able to meet the requirements for use in a radiation-resistant environment. However, the ability of the existing airtight doors of nuclear power plants to be resistant to radiation and uniformly sealed as a whole needs to be improved. Contents of the invention [0003] Purpose of the invention: In order...
