Abstract
The utility model discloses a kind of shock resistance elbow, comprises body, and the radius of curvature of crossing water channel in described body becomes large gradually from feed-water end toward waterexit end; In described body, cross water channel and there is inlet segment, extending section, changeover portion, contraction section and water exit end.(1) the interior radius of curvature of crossing water channel of the utility model body becomes greatly gradually, and therefore the medium in body is less to the impact of inboard wall of tube body, and body is more durable; (2) in the utility model body, cross water channel and there is inlet segment and extending section, pipe in-vivo medium is in the time entering crooked position, flow velocity can reduce accordingly, reduce the impact of medium to inboard wall of tube body, extending section rear portion arranges contraction section, in body, velocity of medium can reduce, and has reduced the impact of pipe in-vivo medium to body.
Description
Technical field
The utility model relates to a kind of elbow, relates in particular to a kind of shock resistance elbow.
Background technique
In pipe-line system, elbow is the pipe fitting (link) that changes pipeline direction, is generally divided into three kinds of 45 degree, 90 degree and 180 degree according to angle, in particular cases also comprises other improper angle elbows such as 60 degree according to requirement of engineering.From material, the material of elbow has cast iron, stainless steel, alloyed steel, malleable cast iron, carbon steel, non-ferrous metal and plastics, etc.In traditional elbow, in the time that pipe in-vivo medium exists hard medium, elbow interior wall is impacted larger, the especially wall of crooked position, affect working life of elbow, and serious meeting causes too early the scrapping of elbow because of deteriorating.
Model utility content
The problems referred to above that exist for prior art, the utility model provides a kind of shock resistance elbow.
To achieve these goals, the utility model adopts following technological scheme: a kind of shock resistance elbow, comprise: body, described body is made up of the first connecting head, the second connecting head and corner, described corner back is higher than corner inside, described body surface is provided with the first socket joint direction signs, the second socket joint direction signs and nameplate, is provided with the first flared type socket joint tube head at the first connecting head jointing, and the jointing of described the second connecting head is provided with the second flared type socket joint tube head; The radius of curvature of crossing water channel in described body becomes large gradually from feed-water end toward waterexit end; In described body, cross water channel and there is inlet segment, extending section, changeover portion, contraction section and water exit end.
Further, described body adopts PPR material to make.
Further, changeover portion is positioned on the wall of corner back side some fins for cushioning is set, and fin is towards water flow direction.
Compared to existing technology, the utlity model has following advantage: the radius of curvature of crossing water channel in (1) the utility model body becomes greatly gradually, and therefore the medium in body is less to the impact of inboard wall of tube body, and body is more durable; (2) in the utility model body, cross water channel and there is inlet segment and extending section, pipe in-vivo medium is in the time entering crooked position, flow velocity can reduce accordingly, further reduce the impact of medium to inboard wall of tube body, described extending section rear portion arranges contraction section, in body, velocity of medium can reduce, and has reduced the impact of pipe in-vivo medium to body.
Brief description of the drawings
Fig. 1 is shock resistance elbow structure figure in embodiment.
Fig. 2 is the inner water channel schematic diagram of crossing of shock resistance elbow in embodiment.
Description of reference numerals: 11-the first connecting head, 110-the first flared type socket joint tube head, 112-the first socket joint direction signs, 12-the second connecting head, 120-the second flared type socket joint tube head, 122-the second socket joint direction signs, 13-corner, 131-corner back, 132-corner inside, 14-nameplate, 21-inlet segment, 22-extending section, 23-changeover portion, 24-contraction section, 25-water exit end, 300-fin.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Embodiment
As illustrated in fig. 1 and 2, in figure, the direction of arrow represents into water direction, a kind of shock resistance elbow, comprise body, described body is made up of the first connecting head 11, the second connecting head 12 and corner 13, described corner back 131 is higher than corner inside 132, described body surface is provided with the first socket joint direction signs 112, the second socket joint direction signs 122 and nameplate 14, be provided with the first flared type socket joint tube head 110 at the first connecting head jointing, the jointing of described the second connecting head is provided with the second flared type socket joint tube head 120.
The radius of curvature of crossing water channel in described body becomes large gradually from feed-water end toward waterexit end; In described body, cross water channel and there is inlet segment 21, extending section 22, changeover portion 23, contraction section 24 and water exit end 25.
The radius of curvature of crossing water channel in body becomes greatly gradually, and therefore the medium in body is comparatively speaking less to the impact of inboard wall of tube body, and body is more durable.In body, cross water channel and have inlet segment and extending section, pipe in-vivo medium is in the time entering crooked position, and flow velocity can reduce accordingly, has further reduced the impact of medium to inboard wall of tube body.Described extending section rear portion arranges contraction section.In body, velocity of medium can reduce, and has reduced the impact of pipe in-vivo medium to body.
In embodiment, body adopts PPR material to make.
Changeover portion is positioned on the wall of corner back side some fins 300 for cushioning is set, and fin 300, towards water flow direction, can further reduce the impact of medium to tube wall.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
