Technical Field
The utility model relates to the technical field of pipeline gas shielded welding, in particular to a quick sealing device for ship pipeline gas shielded welding.
Background
In order to ensure the sailing safety of ships and the necessity of working and living of crews and passengers, pipeline systems are needed on the ships to connect various equipment and instruments for conveying relevant working media such as water, oil, gas and the like. Whether the ship can run reliably and normally or not plays an important role in the technical performance of the pipeline in addition to the technical performance of each device. Due to the characteristics of multiple specifications, multiple varieties and multiple quantities of ship pipelines, heavy pipeline work contents are completed in a short production period, and the heavy pipeline work contents are already key factors influencing the ship construction cost and the construction period.
In order to ensure the welding quality of the pipeline, gas shielded welding is generally adopted for welding. In the traditional gas shielded welding in the industry, water-soluble paper, tin foil paper, paper boards and the like are adopted to plug two ends of a pipeline, protective gas is filled into the pipeline, and air is discharged to form a gas shielded area. Foretell traditional protection mode has following shortcoming, and when the pipeline welding goes on to the certain extent, the welding heat is concentrated, and the arc post temperature is high, and the body is heated and heaies up, can lead to water-soluble paper, tin foil paper, cardboard etc. to be heated and appear becoming flexible or dropping, and intraductal shielding gas runs off, reduces the protecting effect, and the extravagant phenomenon of shielding gas influences gas shielded arc and welds the welding effect. Meanwhile, the plugging process is complicated, the workload and the time are increased, the water-soluble paper, the tin foil paper, the paperboard and the like are disposable and easily-consumed products, and the production cost is a form of gradual progress all year round.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a quick sealing device for pipeline gas shielded welding, which is applicable to a plurality of pipe diameters, is convenient and fast to operate in a sealing process, and solves the problems of long time consumption and gas leakage in pipeline gas shielded welding installation of a sealing tool.
In order to realize the purpose, the utility model adopts the following technical scheme:
the utility model provides a pipeline gas shielded welding welds quick sealing device, includes gas seal protection device, gas seal protection device divide into preceding gas seal protection end cap and back gas seal protection end cap, preceding gas seal protection end cap, back gas seal protection end cap are the taper shape, preceding gas seal protection end cap, back gas seal protection end cap peg graft respectively at the tip of pipeline.
Furthermore, a protective gas inlet and an air exhaust are respectively arranged on the front gas sealing protective plug and the rear gas sealing protective plug.
Furthermore, the gas sealing protection device is made of high-temperature-resistant silica gel materials.
Furthermore, one side of the protective gas inlet is connected with a ball valve.
Furthermore, one side of the ball valve is connected with a quick connector.
Has the advantages that:
through the device, the operation steps of the gas shielded welding sealing process are simplified, a gas shielded area is quickly formed on the inner side of the pipeline, shielding gas is filled into the pipeline before welding, and air in the pipeline is discharged, so that the pipeline meets the welding requirements of gas shielded welding. The device has the advantages of light structure, simple operation, quick switching and connection of protective gas by connecting the ball valve and/or the quick joint on one side of the air inlet, good sealing effect and reduction of consumable consumption and waste of protective gas. The device can realize the pipeline sealing of a plurality of pipe diameters according to the position of the edge of the pipeline pipe diameter size adjusting device matched with the inner wall of the pipeline.
