Problems solved by technology
[0002] At present, many heat treatment furnaces in China are general-purpose furnaces, that is, they need to meet the heat treatment process requirements of various workpieces. When processing shorter workpieces, a large amount of energy needs to be wasted in practical overall furnaces. For energy-saving considerations, usually furnaces The segmented structure is adopted, and each segment has a relatively independent combustion system. When the overall practicality is required, the air pipe needs to be connected. At present, metal hoses are usually used in China to connect, and the air resistance loss is large, the structure is cumbersome, and the failure rate is high. Big security risk

Embodiment Construction
[0012] In order to deepen the understanding of the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, which are only used to explain the present invention and do not limit the protection scope of the present invention.
[0013] Such as figure 1 with figure 2 As shown, this embodiment provides a low-pressure pipe butt joint, including a large connector 1, a small connector 2 and a sealing ring 3. The large connector 1 is in the shape of a hollow circular table with a large outer port and a small inner port. The small connector The head 2 is also in the shape of a circular platform, with a small outer opening and a large inner opening. A layer of sealing ring 3 is surrounded on the inner ring of the large connecting head 1. The small connecting head 2 is inserted into the large connecting head 1 during operation. The outer ring of the small connector 2 is in contact with the sealing ...

The invention discloses a butt joint device for low-pressure pipelines. The butt joint device comprises a large connector, a small connector and a sealing ring. The large connector is in the shape of a hollow circular truncated cone and is provided with a large outer opening and a small inner opening. The small connector is also in the shape of a circular truncated cone and is provided with a small outer opening and a large inner opening. The inner ring of the large connector is surrounded by a layer of sealing ring. The small connector is inserted into the large connector during work, and the outer ring of the small connector is connected with the sealing ring. According to the butt joint device for the low-pressure pipelines, the purpose of segmented and independent heating of a furnace can be achieved, air resistance in the use process is effectively reduced, the structure is simple, use is convenient, adjusting is flexible, and a sealing effect is good.
Description
technical field [0001] The invention relates to the technical field of supporting equipment in the machining industry, in particular to a low-pressure pipeline butt joint. Background technique [0002] At present, many heat treatment furnaces in China are general-purpose furnaces, that is, they need to meet the heat treatment process requirements of various workpieces. When processing shorter workpieces, a large amount of energy needs to be wasted in practical overall furnaces. For energy-saving considerations, usually furnaces The segmented structure is adopted, and each segment has a relatively independent combustion system. When the overall practicality is required, the air pipe needs to be connected. At present, metal hoses are usually used in China to connect, and the air resistance loss is large, the structure is cumbersome, and the failure rate is high. The safety hazard is relatively large. [0003] Therefore, the above-mentioned problems should be considered and so...
