Detailed Description
In order to make the objects, technical solutions and advantageous technical effects of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments;
in the drawings: a pressure relief device for opening a sodium fire-proof airtight door comprises a fixing frame 1 arranged on an airtight door body, a screw rod 4 penetrates through a hole of the fixing frame 1 to be connected and fixed with the fixing frame, sealing covers 6 are arranged at two ends of the screw rod 4 and distributed at two sides of the airtight door, and hand wheels 7 are arranged at two ends of the screw rod 4; the locking device is characterized in that mounting seats 5 are symmetrically arranged on two sides of the sealing cover 6, locking guide rails 9 with limiting grooves 8 inside are arranged in the mounting seats 5, and the locking rods 3 penetrate through limiting holes of the sealing cover 6 and penetrate through the locking guide rails 9.
Specifically, the inner side of the sealing cover 6 is provided with a fireproof layer, so that the overall fireproof performance of the sealed door can be effectively ensured.
Two ends of the screw rod 4 are provided with reverse threads so as to realize linkage of the two sealing covers. The locking guide rail 9 is arranged between the mounting seats 5, a cylindrical boss 10 is arranged at the position of the limiting hole of the sealing cover 6, a limiting groove on the inner surface of the boss 10 is communicated with a limiting groove of the locking guide rail 9, and the limiting groove is arranged along the axial direction of the locking guide rail 9 and penetrates through the whole locking guide rail 9. The locking rod 3 on be provided with spacing groove 8 matched with latch segment 2, spacing groove 8 and latch segment 2 all set up to the swallow-tail form.
The locking blocks 2 are symmetrically arranged at two ends of the locking rod 3, and the middle section of the locking rod 3 is a smooth circle.
The invention is implemented specifically as follows: the pressure relief device is arranged on the sodium fire-proof airtight door, and when the airtight door cannot be opened due to too high indoor and outdoor pressure difference, the pressure relief device is opened to assist in opening or closing the airtight door. During installation, the locking guide rod is rotated, so that the limiting groove of the locking guide rod and the limiting groove of the limiting hole of the sealing cover are on the same straight line; then inserting a locking rod; because the two ends of the locking rod are provided with the limiting blocks matched and locked with the limiting grooves, before the sealing cover is locked, the sealing cover is pushed inwards under the action of the hand wheel and the screw rod, the lug boss is connected and fixed with the sealing plate, and the connecting mode adopts welding or integrated forming; the two sides of the sealing cover are pushed along the limiting grooves; when the sealing cover is locked, the limiting hole of the sealing cover is matched with the smooth circular section of the locking rod, the locking rod is rotated by 90 degrees at the moment, the locking block does not correspond to the limiting groove any more, and the sealing door is locked; the pressure relief device can be operated on both sides of the airtight door, and the pressure relief device can be opened and closed by rotating the hand wheel.
