Abstract
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
The present invention relates to mechanical processing industry corollary equipment technical field, be specifically related to a kind of low pressure pipeline docking adapter.
Background technique
At present, domestic many heat treatment furnaces belong to versatible furnace, the i.e. heat treatment process requirement of demand fulfillment various workpieces, when needs process comparatively casual labourer's part time, practical overall stove needs to waste a large amount of energy, for energy-conservation consideration, for energy-conservation consideration, usual stove adopts segmental structure, each section has relatively independent combustion system, when needs overall practicality, air conduit needs docking, and current domestic usual employing connection by metal hose, moves with body of heater, resistance of air loss is large, structure is lengthy and tedious, and rate of fault is high, and potential safety hazard is larger.
Therefore, the problems referred to above should be paid attention to and the problem solved in the design and use process to heat treatment furnace low pressure pipeline docking adapter.
Summary of the invention
For above-mentioned Problems existing, the invention provides a kind of low pressure pipeline docking adapter.
Technical solution of the present invention is: a kind of low pressure pipeline docking adapter, it is characterized in that: comprise large connecting head, little connecting head and seal ring, described large connecting head is shaped hollow round table, and collar extension is large, interior young, described little connecting head is also in round table-like, young outward, internal orifice is large, and the inner ring of described large connecting head is surrounded with one deck seal ring, described little connecting head operationally inserts in described large connecting head, and the outer ring of described little connecting head connects with described seal ring.
Further improvement of the present invention is: when described large connecting head connects with described little connecting head, gradient differs 5 ~ 15 °.
A kind of low pressure pipeline docking adapter of the present invention, when carrying out pipeline docking, little connecting head inserts in large connecting head, and with large connecting head inner seal circle by pressure contact seal, the gradient of large connecting head and little connecting head is between 5 ~ 15 °.
The invention has the beneficial effects as follows: the present invention can meet the object of stove segmentation independent heating, effectively reduce resistance of air in use, structure is simple, easy to use, and flexibly, good sealing effect, rate of fault is high and for ease of maintenaince in adjustment.
Accompanying drawing explanation
Structural representation when Fig. 1 is the docking of a kind of low pressure pipeline docking adapter of the present invention.
Fig. 2 is the structural representation of a kind of low pressure pipeline docking adapter of the present invention when not docking.
Wherein, the large connecting head of 1-, the little connecting head of 2-, 3-seal ring.
Embodiment
In order to deepen understanding of the present invention, be described in further detail the present invention below in conjunction with drawings and Examples, this embodiment, only for explaining the present invention, not forming protection scope of the present invention and limiting.
As depicted in figs. 1 and 2, the present embodiment provides a kind of low pressure pipeline docking adapter, comprises large connecting head 1, little connecting head 2 and seal ring 3, and described large connecting head 1 is in shaped hollow round table, collar extension is large, interior young, described little connecting head 2 is also in round table-like, outer young, internal orifice is large, the inner ring of described large connecting head 1 is surrounded with one deck seal ring 3, and described little connecting head 2 operationally inserts in described large connecting head 1, and the outer ring of described little connecting head 2 connects with described seal ring 3.When described large connecting head 1 connects with described little connecting head 2, gradient differs 5 ~ 15 °.
A kind of low pressure pipeline docking adapter of the present embodiment, when carrying out pipeline docking, little connecting head 2 inserts in large connecting head 1, and with large connecting head 1 inner seal circle 3 by pressure contact seal, the gradient of large connecting head 1 and little connecting head 2 is between 5 ~ 15 °.
The beneficial effect of the present embodiment is: the present invention can meet the object of stove segmentation independent heating, effectively reduces resistance of air in use, and structure is simple, easy to use, and flexibly, good sealing effect, rate of fault is high and for ease of maintenaince in adjustment.
