Further, the diagonal wedge 53 is fixed to the door frame 1 or the door leaf 2 by bolts, and a spacer 56 for adjusting the height of the diagonal wedge 53 is interposed, and the amount of compression of the sealing strip 3 when the door is closed is changed by adjusting the number of the spacers 56, thereby securing the sealing performance.
The opening and closing angle of the two door pages 2 relative to the door frame 1 is 0-90 degrees, and when the porthole is closed, the outer plate of the door frame 1 and the outer plate of the door pages 2 are flush with the outer plate of the ship body or keep the same line shape, so that the appearance is good.
In addition, the watertight portdoor comprises a bumper 6, a door strike 7 and a door hook 8.
The two ends of the buffer 6 are respectively connected with the inner side surface of the door leaf 2 and the hull, so that the door leaf 2 is stably opened and closed, the buffer 6 is preferably a hydraulic damper or a gas spring, and the buffer 6 is beneficial to stably rotating even if the ship shakes the door leaf 2 due to inconvenient operation of the manual porthole when the ship shakes.
The door stopper 7 is fixed on the hull, and acts on the inner side surface of the door leaf 2, for limiting the opening angle of the door leaf 2.
The door hook 8 is fixed on the ship body, and a fixing hole 27 which is matched with the door hook 8 to be inserted is arranged on the inner side surface of the door leaf 2 and is used for locking the position of the door leaf 2.
Closed state: as shown in fig. 1, when the porthole is closed, the outer plate of the door frame 1 and the outer plate of the door leaf 2 are flush with the outer plate of the ship body or keep consistent with the line type; as shown in fig. 2, the locking wedge 52 of the locking device is pressed against the wedge 53; the flange 11 of the door frame 1 presses the side seal 31 of rectangular cross section as shown in fig. 5 and 6, and the center seam seal 32 of the two door leaves 2 is kept pressed.
The opening process comprises the following steps: the driving hand wheel 45 on the door leaf 2 is rotated, the linkage rotating shaft 42, the first gear 44, the second gear 46 and the gear disc 47 rotate, and then the connecting rod 54 of the locking mechanism 5 is driven by the connecting rod shaft 48 to drive the locking wedge 52 to rotate, so that the contact surface of the locking wedge 52 and the inclined wedge 53 is separated, and the door leaf 2 is opened around the hinge. Because wedge locking exists between the two door leaves 2, attention is required to the sequence of opening the two door leaves 2.
Open state: the door leaf 2 is opened to be in contact with the door bump 7, the buffer 6 is contracted to realize stable opening in the process, and then the door hook 8 is inserted into the fixing hole 27 on the door leaf 2 to form locking, as shown in fig. 4.
