Seawater tank sealing test device

Abstract

The invention relates to a seawater tank sealing test device. The seawater tank sealing test device comprises a reinforcing ring welded at an opening of an outer plate of a seawater tank, wherein inner and outer ends of the reinforcing ring surpass two side surfaces of the outer plate, the inner end of the reinforcing ring is provided with a sealing plate, periphery of an outer end surface of thesealing plate is provided with a groove, the inner end of the reinforcing ring is in the groove, the outer end of the reinforcing ring is provided with a pressure plate, and the pressure plate is connected with the outer end surface of the sealing plate through a bolt. The seawater tank sealing test device is advantaged in that the structure is simple, the seawater tank sealing test device is convenient to mount, the sealing plate and the pressure plate are tightened and fixed through the dual-head bolt, sealing between the sealing plate and the reinforcing ring is achieved, after the test, the dual-head bolt is loosened and the sealing plate is taken down, later re-utilization is facilitated, detachable repeated use is realized, and work efficiency is improved.

Description

technical field [0001] The invention relates to a seawater tank sealing test device. Background technique [0002] The ship's sea water tank is an independent compartment, and an opening grille is opened on the outer plate so that the ship can obtain sea water from here. During the construction of the ship, it is necessary to conduct a sealing test on the weld seam of the seawater tank cabin wall, and do a water pressure test on the strength of the cabin wall, which requires sealing the openings on the outer plate. In the past, a piece of outer plate was processed Steel plates with the same line type and a surrounding wall are added to form a pentahedron box, and then the box and the outer plate are welded to close the opening of the outer plate, and the box is cut off after the tightness test and strength test are completed , the root part should be polished and smooth, and the paint damaged by welding is not good at the end. The wall of this box needs to be replaced every...

During the construction of the ship, it is necessary to conduct a sealing test on the weld seam of the seawater tank cabin wall, and do a water pressure test on the strength of the cabin wall, which requires sealing the openings on the outer plate. In the past, a piece of outer plate was processed Steel plates with the same line type and a surrounding wall are added to form a pentahedron box, and then the box and the outer plate are welded to close the opening of the outer plate, and the box is cut off after the tightness test and strength test are completed , the root part should be polished and smooth, and the paint damaged by welding is not good at the end. The wall of this box needs to be replaced every three ships, resulting in a waste of materials; and it is very heavy, inconvenient to operate, and requires many people to operate; in use Welding and cutting are also required, tools and corresponding personnel need to be prepared, and the efficiency is not high
