Technical Field

The invention relates to the field of watertight maintenance, in particular to a large-scale vulcanization tool in a flow guide cover and an operation method.

Background

At present, the sealing between the mounting flange of a large-scale matrix in some old ships and the ship shell fails due to the aging of a sealing element, so that the water in the air guide sleeve leaks to the upper cabin. The most fundamental solution for watertight recovery between the flange and the warship body is to disassemble the array and the flange plate, replace the sealing element and then reinstall the sealing element again. Due to the fact that upper cabin pipelines are numerous, the flange connecting nut is corroded seriously and the like, the air guide sleeve cannot be opened, and under the condition, the scheme is difficult to implement and even cannot be operated.

Under the condition of not dismounting the array, a layer of rubber is vulcanized at the joint between the flange and the warship body for watertight sealing. Due to the limited space of the air guide sleeve and the poor construction environment, the joint size between the array flange and the naval vessel shell is large, the general circumference is 2-3 m, and the heating and pressurizing vulcanization operation cannot be carried out by adopting professional vulcanization equipment, so that a special tool needs to be designed to assist construction.

The small-size parts on site in the air guide sleeve are generally vulcanized by a small vulcanizing machine, and the large-size parts such as the large array flange in the air guide sleeve cannot be vulcanized by the small vulcanizing machine. The rubber can be wrapped manually, and heated by electric iron or other tools for simple vulcanization.

Generally speaking, the presses available on site are restricted by manholes and tend to be small in size, thus limiting the size of the serviceable parts. The seam between the large array flange and the naval vessel shell has a large size, the general circumference is 2-3 m, and the large standard vulcanizing machine is too large in size and cannot pass through a manhole, and is only suitable for pressure vulcanization of a flat plate and cannot pressurize the seam. The water tightness reliability is affected by the defects of insufficient rubber compactness, air holes and the like due to simple heating. If the sealing element is replaced, the air guide sleeve needs to be disassembled, and the large-scale matrix needs to be installed again.
