Embodiment Construction

[0014] The nuclear power push-pull airtight door of the present embodiment is as Figure 1 to Figure 3 As shown, the angle steel door frame 1 is welded with embedded parts and fixed at the door opening of the building through expansion bolts, and sealed with the door opening with silica gel. A horizontal guide rail mounting frame 2 extending horizontally is fixed on the door frame 1. The mounting frame 2 The horizontal guide rail 4 is hoisted by the vertical fastening bolt 3 . In order to compensate the pressing stroke of the thick door leaf, the fastening bolt 3 passes through the long slot hole extending in the direction of the door frame of the installation frame 2, so that not only the initial position of the horizontal guide rail 4 can be adjusted as required during installation, but also a certain compensation function can be formed. mobile vice.

Abstract

The invention relates to a nuclear power push-pull airtight door belonging to the technical field of nuclear power special facilities. The airtight door comprises a door frame fixed on a building door opening, wherein a horizontal guide rail with a hanging pulley wheel is fixedly arranged on the door frame; a door sash is hung below the hanging pulley wheel through a short connecting rod; the outer side of a door plate of the door sash is provided with a side frame with a profile being larger than the inner profile of the door frame; the inner side of the door plate is provided with a door body which protrudes towards the door frame and has a profile being smaller than the inner profile of the door frame; sealing strips are fixed around the door body; a group of positioning screw rods with compression hand wheels extending towards the door sash is fixed at one side of the door frame; a group of nuts is fixed at the other side of the door frame; one side of the door sash is provided with a group of horizontal guide grooves corresponding to the positions of the screw rods respectively; and the other side of the door sash is provided with a group of locking hand wheels with screw rods, which correspond to the positions of the nuts respectively. By adopting the airtight door, the door sash can be opened and closed by freely pushing and pulling and can be moved towards the door frame within a certain range, so that compressing force can be applied by using a locking mechanism, the sealing strips are utilized effectively, and reliable sealing is realized.

Description

technical field [0001] The invention relates to an isolation door, in particular to a nuclear power push-pull airtight door, which belongs to the technical field of nuclear power special facilities. Background technique [0002] When the nuclear power plant unit is running, the pressure value of each area is required to be strictly controlled, so the partition doors between each area must not only have sufficient strength, but also need to have reliable airtightness. For conventional hinged doors, since there is a pressing force between the door leaf and the door frame when closing, the sealing problem is easier to solve. But for the push-pull airtight door of push-pull opening and closing, it is a difficult problem to realize reliable sealing. [0003] The typical structure of the existing hanging type sliding door is as disclosed in the Chinese patent application number 200820020446.0, including the upper frame of the door, the door frame and the door leaf, the upper fram...
