Abstract

The invention discloses a tool for testing the tightness test of a ship pipeline. The tool comprises a sealing cover arranged on the pipe opening of a sleeve. A sealing rubber is arranged below the sealing cover, and a through hole formed in the middle of the sealing cover. One end of the through hole is communicated with the interior of the sleeve. The other end of the through hole is connected with an air inflation device. A clamping hoop is clamped at the joint part of the sleeve and the pipeline. The head parts of a plurality of bolts are configured to abut against the lower part of the clamping hoop. The tail parts of the bolts penetrate through the clamping hoop. The sealing cover protrudes out of the upper part of the sealing cover. A plurality of nuts are connected with the bolts in the one-to-one correspondence mode. The nuts abut against the upper portion of the sealing cover. According to the invention, the tool does not need to be welded in the installation process, thus being safe, quick and convenient in operation. Meanwhile, the damage of the paint in the welding process can be avoided. As a result, the paint can be prevented from being repaired.

Description

technical field

[0001] The invention belongs to the technical field of shipbuilding, and in particular relates to a tool for tightness testing of ship pipelines. Background technique

[0002] In the process of ship construction, it is necessary to do a tightness test on the installed pipeline. The usual method is to inject a certain pressure of compressed air, nitrogen or water into the pipeline and then keep the pressure for a period of time. Check the pipeline by observing the pressure change. The sealing performance of the installation of the pipeline system (including pipes and accessories such as flanges, valves, casings, etc.).

[0003] This article takes the most commonly used compressed air medium tightness as an example to illustrate. If there are flanges or threaded joints in the pipeline system, you can directly use the inflatable tooling in the form of flanges or threaded joints, but if it is in the form of a sleeve, you cannot directly install the inflatable to...
