Combined sealing strip for underwater cabin observation window

Abstract

The invention relates to a combined sealing strip for an underwater cabin observation window. The combined sealing strip comprises a male sealing strip and a female sealing strip which are connected in a matched way. The cross section of the male sealing strip is in the shape of an inverted T, a protruding connecting end is formed on an upper part of the male sealing strip, a cavity is made in theprotruding connecting end, and U-shaped grooves are symmetrically formed in two side walls of the lower part of the male sealing strip. The cross section of the male sealing strip is in the shape ofa letter U, a sealing and embedding groove adapted to the protruding connecting end of the male sealing strip is formed in the female sealing strip, and a vibration damping chamber is arranged in themiddle of the female sealing strip, lip-shaped grooves are symmetrically formed on two sides of a lower part of the female sealing strip, end grooves are formed at a root of the protruding connectingend on the male sealing strip, and ribs adapted to the end grooves of the male sealing strip are formed on two side groove wall ends of the sealing and embedding groove. According to the combined sealing strip, the male sealing strip and the female sealing strip are matched and connected in the form of plugging, the overall sealing of an observation window is ensured, and the vibration damping effect is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of shipbuilding, and relates to a sealing technology for an observation window of a launching tank, in particular to a combined sealing rubber strip for the viewing window of a launching tank. Background technique [0002] The observation window sealing strip of the submarine's launching compartment is one of the important parts of the launching compartment, and it should have the functions of sound insulation, dustproof, water seepage prevention and shock absorption. Generally, the sealing strip of the observation window is required to be convenient for injection molding processing, has a certain degree of elasticity, appropriate hardness, and small compression permanent deformation, is not easy to decompose and harden, and can maintain a good sealing state for a long time. However, due to the submarine's water tank The observation window sealing strip is always under water, which has relatively higher requ...

AI Technical Summary

Problems solved by technology

Generally, the sealing strip of the observation window is required to be convenient for injection molding processing, has a certain degree of elasticity, appropriate hardness, and small compression permanent deformation, is not easy to decompose and harden, and can maintain a good sealing state for a long time. However, due to the submarine's water tank The observation window sealing strip is always under water, which has relatively higher requirements on the structure and corrosion resistance of the sealing strip

Generally, a single-shaped sealing strip can no longer meet the needs
