Outboard pipe pressure testing sealing tool and outboard pipe device

Abstract

The invention provides an outboard pipe pressure testing sealing tool. The outboard pipe pressure testing sealing tool comprises a fixing frame for a pipe body of an outboard pipe to penetrate, a sealing piece for sealing an end opening of the pipe body of the outboard pipe, a plurality of pairs of fixing pieces which are oppositely arranged and at least two sets of connection assemblies for positioning the sealing piece. With the side face, for the pipe body of the outboard pipe to penetrate, of the fixing frame as a first reference face, the sealing piece is parallel to the first reference face. The sealing piece comprises a sealing adhesive piece opposite to the fixing frame, the connection assemblies penetrate the sealing piece to be fixedly connected to the fixing frame, the sealing piece is in slidable connection with the connection assemblies, the fixing pieces are extensively and retractably connected to the fixing frame, and the extending and retracting directions of the fixing pieces are parallel to the first reference face. The sealing tool can be rapidly assembled to the outboard pipe and can also be rapidly disassembled from the outboard pipe, the sealing work efficiency is effectively improved, the consumed time is relatively short, the outboard pipe pressure testing sealing tool can be repeatedly used, and the energy consumption in the working process and the waste of the labor cost can be greatly reduced.

Description

technical field [0001] The invention relates to an outboard pipe pressure test sealing tool and an outboard pipe device. Background technique [0002] The outboard pipe refers to the pipe structure with a flange welded at one end in the field of hull tooling. The outboard pipe of the ship under construction needs to be pressure tested in the workshop according to the requirements of relevant specifications. After inspection, the outboard pipe has no leakage. Can be installed on board. Since the outboard pipe has only one end with a flange, and the other end is a free end, such as figure 1 As shown, in order to test the pressure of the outboard pipe, the free end of the outboard pipe needs to be sealed. The current method of sealing the outboard pipe is to use an iron plate whose size is consistent with the free end of the outboard pipe to be welded at the free end of the outboard pipe, such as figure 2 As shown, the pressure test pump is then used to connect the flange e...

AI Technical Summary

Problems solved by technology

The current method of sealing the free end of the outboard pipe mainly has the following disadvantages: material waste, the iron plate used for sealing can only be used once, and after the pressure test is completed, it cannot be used again after being cut from the outboard pipe; energy waste, In order to install and remove the iron plate on the free end of the outboard pipe, processes such as welding, grinding, and cutting are required. These processes use a large amount of energy such as carbon dioxide gas, compressed air, oxygen, and acetylene; The work of installing iron plates on the top requires plumbers, welders, grinders and other types of work; the sealing efficiency is low, because the sealing of the free end of the outboard pipe involves multiple processes and multiple types of work, the sealing efficiency is low and it takes a long time
