Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] Such as figure 1 As shown, a multi-point locking double-cover sealing device is composed of a lower door assembly, an upper door assembly and a locking tool. The lower door assembly and the upper door assembly are respectively installed on two On the connected equipment, the upper door assembly is made up of upper door seat 9, upper door panel 7, upper door locking and unlocking device, upper sealing ring 8 and the like. The upper door seat 9 is used to support other parts of the upper door, and is installed on the upper equipment 1 by screws; the upper door plate 7 is installed in the upper door seat 9, and is the main structure of the upper door. In this embodiment, the locking and unlocking device for the upper door is composed of three sets of bolt shaft 4, bolt 5 and gland 6 (not limited to three sets in practical application, 2 se...

Abstract

The invention relates to a multi-point locked double-cover sealing device and belongs to the field of design of sealing transfer devices. The multi-point locked double-cover sealing device comprises an upper door component, a lower door component and a special tool, wherein each of the upper door component and the lower door component comprises a round door plate, a door seat and multiple sets of locking and unlocking devices; the door plate is arranged in the door seat; the multiple sets of locking and unlocking devices are arranged around the center of the door plate uniformly; a groove is formed at the lower end of a latch of the upper door locking and unlocking device; the latch passes through the lower door plate and is matched with a lock shaft of the lower door locking and unlocking device; the lower end of the lock shaft is connected with a clamping plate which rotates together with the lock shaft; the lock shaft is rotated by the special tool, so that the clamping plate is screwed in or out of the groove in the lower door seat and the lower door seat is separated from the lower door plate; and the latch is connected with the lower door plate, so that the upper door plate and the lower door plate are meshed with each other, sealing reliability in any state is guaranteed, and radioactive gas does not enter a personnel operating region.

Description

technical field [0001] The invention belongs to the design field of sealing transfer devices, in particular to a multi-point locking double-cover sealing device used to prevent radioactive gas from leaking in a radioactive environment. Background technique [0002] It is necessary to transfer radioactive substances between sealed equipment, or to overhaul, clean, or scrap radioactive equipment. These processes are likely to cause short-term or instantaneous loss of sealing and negative pressure, causing radioactive gas to overflow. In order to ensure the safety of personnel, The whole process must be sealed. When the above operations are carried out in the radioactive factory building, the sealing device is used to ensure the sealing between the equipment. The existing similar double-cover sealing device (201120207456) realizes the locking and unlocking of the sealing door by rotating the pull rod, locking the chuck, etc. The rotating tie rod is installed at the center of t...
