Abstract

The invention discloses a pipe orifice rainproof protection device in ship industry. The device comprises a rubber plug, a sealing circular plate, a first elastic ring, a second elastic ring, a third elastic ring and an elastic sealing mechanism, the rubber plug is arranged in a pipe orifice, one end of the rubber plug is connected with the sealing circular plate, the sealing circular plate is located on the outer side of a flange, the sealing circular plate is provided with the first elastic ring in the circumferential direction, the outer ring of the first elastic ring is fixedly connected with one side of the second elastic ring, the other side of the second elastic ring is connected with the outer side of the third elastic ring, and the third elastic ring is located on the inner side of the flange. According to the device, the flange is wrapped by the first elastic ring, the second elastic ring and the third elastic ring, so that the flange cannot be exposed when the device is not taken down, the flange pipe orifice cannot be connected through the flange, and an operator is prevented from forgetting the device when connecting a pipeline.

Description

technical field [0001] The invention relates to the technical field of protection of pipe fittings with flanges at nozzles of ships, in particular to a rainproof protection device and protection method for nozzles in the shipbuilding industry. Background technique [0002] The number of pipe fittings involved in the shipbuilding industry is huge, there are many types, and the sizes are different. Most of the pipe fittings are mainly in the form of flanged nozzles. After the pipe fittings are manufactured, they are sent to galvanizing, and then sent to the module yard for waiting Assembly often takes a long time and is uncertain. Whether it is protection during transportation or waterproof and anti-rust protection during storage, the existing protection devices are easy to detach during use, and are easy to be forgotten after installation, making the operator Forgetting to remove the device when connecting the tubes, resulting in unusable after the tubes are connected. For t...
