Abstract

The utility model discloses a novel elbow comprising a pipe. The pipe comprises a first connector, a second connector, and an arc bend. The back of the bend is higher than the inner side of the bend. The surface of the pipe is provided with a first socketing direction sign, a second socketing direction sign, and a nameplate. The transition part between the first connector and the bend is provided with a first circular boss. The transition part between the second connector and the bend is provided with a second circular boss. The connection of the first connector is provided with a first flared socket head; the connection of the second connector is provided with a second flared socket head. The novel elbow is characterized in that the outer side of the interior of the bend is provided with a buffer structure composed of a plurality of spring plates facing in the flowing direction of fluid. Through the design of the spring plates, impact is effectively reduced; when medium carrying excess impact force acts on the bend of the elbow, the impact force weakens with deformation of the spring plates, the bend is protected correspondingly, and breakage rarely occurs.

Description

A kind of novel elbow

Technical field

The utility model relates to a kind of novel elbow, belongs to pipe joint field.

Background technique

In pipe-line system, elbow is a kind of link of indispensability, due to elbow turning point generally all at an angle, therefore all need to consider the impact resistance of elbow.Traditional approach is, at elbow turning point, reinforcement structure is set.The patent that for example patent No. is CN201310261944.X, it discloses a kind of impact resistance plastics elbow, include elbow main body, the position that is positioned at bent arc in described elbow main body is provided with a baffle plate, the two ends of described baffle plate are fixedly connected with elbow main body inner side, in the cavity that described baffle plate and elbow main body form, perpendicular to baffle plate, are provided with at least one stiffening rib.This scheme exists following not enough: 1, complex forming technology, is not easy to industrialization; 2, baffle arrangement forms certain retardance to elbow inner fluid.

Model utility content

The problems referred to above that exist in order to solve prior art, the utility model provides a kind of novel elbow.

To achieve these goals, the utility model adopts following technological scheme:

A kind of novel elbow, possesses body, described body is comprised of the first connecting head and the second connecting head and curved 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, described the first connecting head and corner transition portion are provided with the first annular boss, described the second connecting head and corner are provided with the second annular boss at transition portion, at the first connecting head jointing, be provided with the first flared type socket joint tube head, the jointing of described the second connecting head is provided with the second flared type socket joint tube head; It is characterized in that: outside, described corner inside is provided with buffer structure, and described buffer structure is some shell fragments, and described shell fragment is towards fluid flow direction.

Can be improved further and be: described buffer structure is that many rows shell fragment group of arranging along fluid flow direction forms, every row's shell fragment group is vertical with fluid flow direction, and every row's shell fragment group consists of some shell fragments.

Can be improved further and be: described shell fragment and corner angle are 30～45 degree.

Can be improved further and be: this shell fragment is plastic material.

Compared to existing technology; the utlity model has following advantage: shell fragment design of the present utility model effectively alleviates impact, and when the excessive medium of impact force acts on elbow corner, impact force can weaken along with the deformation of shell fragment; the corresponding corner of having protected, therefore be difficult for breaking.

Accompanying drawing explanation

Fig. 1 is a kind of novel elbow overall structure figure.

Fig. 2 is a kind of novel elbow internal structure schematic diagram, the figure shows shell fragment.

Fig. 3 is a kind of example of shell fragment.

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.

The elbow that this case relates to can be one eighth bend or 90 degree elbows or 135 degree elbows.The present embodiment is take one eighth bend as example.

As Fig. 1, shown in 2, a kind of novel elbow, possesses body, described body is comprised of the first connecting head 11 and the second connecting head 12 and curved 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, described the first connecting head 11 is provided with the first annular boss 111 with corner 13 transition portions, described the second connecting head 12 is provided with the second annular boss 121 with corner 13 at transition portion, at the first connecting head 11 jointings, be provided with the first flared type socket joint tube head 110, the jointing of described the second connecting head 12 is provided with the second flared type socket joint tube head 120, the inner outside of described corner 13 is provided with buffer structure, described buffer structure is some shell fragments 100, described shell fragment 100 is towards fluid flow direction, this shell fragment is plastic material.

Fig. 3 is elastic piece structure schematic diagram, and this shell fragment possesses the bottom that is square and curved top.It should be noted that, elastic piece structure form is more, is not limited to said structure, and meanwhile, shell fragment should adopt has flexible material, and its cushioning effect is better.

Buffer structure is that many rows shell fragment group of arranging along fluid flow direction forms, every row's shell fragment group is vertical with fluid flow direction, and every row's shell fragment group consists of some shell fragments.

As a kind of preferred arrangement, described shell fragment is 30～45 degree (angle that shell fragment becomes with the tangent line of shell fragment root corner of living in) with corner angle.

When the excessive medium of impact force acts on elbow corner, impact force can weaken along with the deformation of shell fragment, and the corresponding corner of having protected, therefore be difficult for breaking.

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.
