Problems solved by technology
[0004] 1. This type of plugging requires welding during construction. After the test, it is necessary to remove the temporary sealing plate and polish the nozzle. The entire construction period is long and the labor efficiency is low.
[0005] 2. In the process of welding and cutting off the temporary sealing plate, the spray coating layer on the inner wall of the pipe will be damaged, which is difficult to repair, resulting in easy corrosion and damage of the pipe, and the product quality cannot be guaranteed

The invention relates to the technical field of ship construction, in particular to a ship pipeline orifice plugging tightness device. The ship pipeline orifice plugging tightness device comprises a stretching connecting plate, a rubber part which is arranged on the stretching connecting plate, a thrust plate which is arranged on the rubber part, a supporting mechanism which is arranged on the thrust plate and a stretching rod which can movably penetrate through the rubber part, the thrust plate and the supporting mechanism, one end of the stretching rod is fixedly connected with the stretching connecting plate, the other end is in threaded connection with a tensioning nut, the tensioning nut is in pressure contact with the supporting mechanism, the stretching connecting plate, the rubberpart and the thrust plate are all in a round shape matched with the cross section shape of an inner hole of a ship pipeline, and the supporting mechanism can stretch out and draw back in the radial direction of the stretching rod; and the invention further relates to a using method of the device. The supporting mechanism extends to be in pressure contact with the inner hole wall of the ship pipeline, supporting and fixing of the device are achieved, the tension nut is screwed to enable the stretching connecting plate to extrude the rubber part in the direction towards the thrust plate till therubber part expands and is attached to the inner hole wall of the ship pipeline, and sealing of the inner hole is achieved.
Description
technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a sealing and sealing device for a pipe opening of a ship and a method for using the sealing and sealing device for a pipe opening of a ship. Background technique [0002] In the process of ship construction, the system pipelines installed on the ship are like animal tissue blood vessels, distributed in various positions of the ship, and the system is huge and complicated. The oil, water, gas, wind, etc. needed for the normal operation of the ship need to be continuously supplied to various types of equipment on the ship through the pipeline system. Based on the functional characteristics of the ship's pipeline, after the pipeline structure installed on the ship is completed to form a system, it is necessary to conduct a tightness and strength test on the pipeline in the system to ensure the safety and stability of the medium transmitted in the pipeline. In the process of p...
