After the ship leaves the factory and is launched, there are many vulnerable parts on the ship, such as ship doors and Windows. In addition to normal wear and tear, there are also parts on the ship that are damaged due to accidents and other reasons. This involves the need for timely replacement, to avoid the danger caused by faults when the ship is sailing. The manufacture of ship fittings requires a high technical level and manufacturing level. The production requirements of ship fittings are very high, and the precision of fittings is required to be higher. Just think about it, ships are traveling in the vast sea or rivers, relative to land traffic, it has a certain risk index, so every machine equipment and spare parts have strict manufacturing standards, to ensure the normal operation of the ship.
Generally, the elastic flame-retardant rubber with an air gap is used to stick on the positioning surface of the door in a sticky way. The height is easy to control and the compression is large. When the pre-tightening force of the door reaches a certain degree, the sealing effect is very good, and the opening and closing are guaranteed free and the operation is convenient. (3). The design of the escape door pressing mechanism: the seal of the escape door needs a certain amount of external force to press the elastomer and produce the sealing effect, and the device producing the pressing force in the escape door usually has the following two kinds: The first is the use of spiral rotation to make the locking tongue sliding along the inclined plane (5°) to produce locking force, this mechanism locking reliable, large compression force, strong self-locking ability, but the structure is more complex, not compact enough. It takes up a lot of space, but there are still many manufacturers using this structure.
