Abstract
The invention discloses a double-flange plate. The double-flange plate is characterized by comprising a first flange (1) and a second flange (2), the two of which are the same and arranged at the two ends of a connecting tube (3), wherein a central through hole (4) is formed to penetrate through the first flange (1) and the second flange (2); polygonal lugs (5) are formed in a circle at the periphery of the central through hole (4); the first flange (1) and the second flange (2) are discs; a plurality of grooves (7) are evenly formed at the edge of each disc; a plurality of cambered slotted holes (6) are evenly formed in each disc next to the edge. The double-flange plate is simple in structure, good in airtightness, secure in plate body, excellent in thermal insulation property, suitable for occasions needing to keep warm and high in practicability.
Description
Technical field
The present invention relates to mechanical fitting field, particularly relate to a kind of double flange.
Background technique
At present, the application of double flange is more and more wider, and the performance impact of its each side its scope used and occasion, and have very large space to its research, for the use occasion of cold, the performance of flange more needs reliable and stable.
Summary of the invention
The present invention, in order to solve the problem of prior art, provides a kind of double flange.
In order to reach above object, the technological scheme that the present invention adopts is: a kind of double flange, it is characterized in that, comprise the first identical flange 1 and the second flange 2 being arranged on connecting tube 3 two ends, run through the first flange 1 and the second flange 2 is provided with central through bore 4, the outer of described central through bore 4 is arranged with a circle polygonal projection 5, described first flange 1 and the second flange 2 are circular discs, the limit of circular discs is evenly provided with some grooves 7, on circular discs is kept to the side, is evenly distributed with some arc-shaped slots 6.
As preferably, be wound with warming snub rope at described connecting tube external spiral.
The invention has the beneficial effects as follows: double flange structure of the present invention is simple, good airproof performance, disk body is firm, and cold-proof performance is good, is applicable to and needs warming occasion, practical.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Embodiment
All features disclosed in this specification, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Arbitrary feature disclosed in this specification (comprising any accessory claim, summary and accompanying drawing), unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
As Fig. 1, a kind of double flange provided by the present invention, it is characterized in that, comprise the first identical flange 1 and the second flange 2 being arranged on connecting tube 3 two ends, run through the first flange 1 and the second flange 2 is provided with central through bore 4, the outer of described central through bore 4 is arranged with a circle polygonal projection 5, and described first flange 1 and the second flange 2 are circular discs, the limit of circular discs is evenly provided with some grooves 7, on circular discs is kept to the side, is evenly distributed with some arc-shaped slots 6.Warming snub rope is wound with at described connecting tube 3 external spiral.
The double flange structure of invention is simple, good airproof performance, and disk body is firm, and cold-proof performance is good, is applicable to and needs warming occasion, practical.
The present invention is not limited to aforesaid embodiment.The present invention expands to any new feature of disclosing in this manual or any combination newly, and the step of the arbitrary new method disclosed or process or any combination newly.
