Tool for sea chest airtightness tests

Abstract

The invention discloses a tool for sea chest airtightness tests. The tool comprises a bottom plate and a cover plate; the bottom plate is arranged at the inner side of a sea chest; the bottom plate can cover the sea chest from the inner side; a plurality of threaded columns facing the outer side of the bottom plate are fixedly connected to the bottom plate; nuts are connected to the threaded columns; a first short pipe and a second short pipe are arranged on the bottom plate; the first short pipe and the second short pipe are distributed at two ends of the bottom plate respectively; two ends of the first short pipe and two ends of the second short pipe are communicated with the inner side space and outer side space of the sea chest; the cover plate is arranged at the outer side of the seachest; the cover plate can cover the sea chest from the outer side; and hole structures allowing the threaded columns to penetrate through are formed in the cover plate. The tool disclosed by the invention can be used for sea chest airtightness tests. The tool has the advantages of simplicity in use, easiness in operation, high safety, high reliability and universality.

Description

Technical field [0001] The invention belongs to the technical field of ship construction, and in particular relates to a tooling used for the air tightness test of a seabed door. Background technique [0002] In the process of ship construction, the seabed door air tightness test is an item that must be submitted for inspection before the ship leaves the dock. The submarine door is an open non-closed space. Before the air tightness test, it must be closed as a closed space. At the same time, the air inlet pipe and the air outlet pipe must be selected to continue the air tightness test. In the past, the airtight test of the submarine door usually used a method of welding and sealing the opening with a steel plate, which not only increased the workload of welding and cutting, but also the steel plate around the submarine door deformed greatly after cutting, and pyrotechnic correction was required. It also increased the workload. Summary of the invention [0003] In view of the pro...
