Description
Technical Field
The utility model relates to the technical field of welding tools, in particular to a multifunctional steel pipe plug for welding.
Background
When the traditional stainless steel and carbon steel pipes are welded by manual argon arc welding or semiautomatic argon arc welding, the pipe orifices of two pipelines to be welded are sealed by adopting water-soluble paper and adhesive tapes, and the defects that the inflation time is long, a large amount of argon is wasted, and materials for plugging the pipe orifices such as water-soluble paper, gaskets and the like cannot be reused and the like are overcome. In addition, the welding thin-wall stainless steel pipe is plugged by plugs, but the welding thin-wall stainless steel pipe has various sizes with different specifications, so that the welding thin-wall stainless steel pipe is inconvenient to use because the welding thin-wall stainless steel pipe is required to be provided with the plugs with various specifications.
Disclosure of Invention
Aiming at the requirements, the utility model provides the multifunctional steel pipe plug for welding, which can be used for argon arc welding construction of the thin-wall stainless steel pipe for welding with five specifications of DN40-DN15, has the advantages of multiple purposes, strong applicability, convenient assembly and disassembly, repeated use and material saving.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a multi-functional steel pipe end cap for welding, the steel pipe end cap includes tail section and a certain amount of inserted section that connects gradually, and the diameter reduces in proper order from the tail section to the inserted section diameter of forefront and is step-like structure, is equipped with the through-hole that runs through in the middle of tail section and the inserted section, and the one end that the through-hole is close to the tail section is equipped with the screw thread section. The tail section and the insertion section are arranged in sequence from small to large to form a pagoda shape or a step shape, the argon-filled plastic pipeline is connected with the plug through the threaded section, the plug is sealed at one end of the pipeline, the other end of the pipeline can be connected with the plug by using the same plug, the threaded needle valve can be connected with the plug after connection, the valve is opened at a certain angle, the air flow is ensured to be smooth, the valve of the argon cylinder is opened, the whole welding part is ventilated, and then welding can be performed.
Preferably, the front end of the insertion section is provided with a chamfer angle, so that the insertion section can be conveniently inserted into the steel pipe.
Preferably, the steel pipe plug is made of stainless steel, PTFE or other materials.
Preferably, the steel pipe plug is formed by turning bars made of stainless steel, PTFE or other materials.
Preferably, the number of insertion sections is 5 sections.
Preferably, the insertion section is adapted to the inner diameter of a steel tube of the size DN15-DN 40. The insert section is formed by cutting the inner diameter of a DN15-DN40 steel pipe (the wall thickness of the pipe is 1.5 mm), 30 wires are reduced, the plug insert section is convenient to enter the steel pipe, and the installation and the disassembly are convenient.
The utility model has the advantages that: 1. the steel pipe plug can be used for argon arc welding construction of the thin-wall stainless steel pipe for welding with five specifications of DN40-DN15, and has multiple purposes and strong applicability; 2. the argon consumption is reduced, the protection effect is good, and the cost is reduced; 3. the disassembly and assembly are convenient, the device can be used repeatedly, and the material consumption is saved.
