Abstract

The utility model discloses a kind of Welded fitting, its drip irrigation device be comprise welding body in a tubular form and with weld body one and the coaxial connecting tube arranged, the end wall welding body is set to face of weld, face of weld is provided with multiple concave curvature.The purpose of this utility model is to provide a kind of bonding area increased between pipe joint body and pipeline, to increase the Welded fitting of stability and the sealing of welding between face of weld with pipeline.

Description

Welded fitting

Technical field

The utility model relates to a kind of Welded fitting.

Background technique

Welded fitting Applicable media: the non-aggressives such as Oil, Water, Gas or Korrosionsmedium.To welding type sealed pipe joint, the specification requirement of adapted steel pipe is more flexible, by the effect of more than two or two pipeline conductings, thus can be widely adopted in a lot of field with after pipeline welding, be also applicable to the hydraulic transmission pipelines such as various mechanical engineering, machine tool simultaneously.

But due to vibration that equipment operationally can continue in a lot of situation, simultaneously because face of weld on pipe joint is less or face of weld is plane, so cause not prison welding solid, add the vibration of equipment, therefore there is the situation of splitting between the face of weld of pipe joint and pipeline, thus cause the sealing of pipe joint to be destroyed, and liquid medium in the duct flows out, the situation polluting or waste, therefore also exists the space of improvement.

Model utility content

For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of bonding area increased between pipe joint body and pipeline, to increase the Welded fitting of stability and the sealing of welding between face of weld with pipeline.

For achieving the above object, the utility model provides following technological scheme: a kind of Welded fitting, comprise welding body in a tubular form and with weld body one and the coaxial connecting tube arranged, the end wall welding body is set to face of weld, face of weld is provided with multiple concave curvature.

Preferably, concave curvature is extended along the circumferential surface of welding body.

Preferably, concave curvature is provided with two.

Preferably, the symmetrical setting of diameter of concave curvature correspondence welding body.

Preferably, the area of each described concave curvature is 1/2nd of whole face of weld area.

Preferably, on connecting tube projection and face of weld.

Compared with prior art, the utility model has the advantage of: in the technical program, owing to face of weld being provided with multiple concave curvature, so the bonding area of whole face of weld can increase relatively, make welding of the present utility model firm and stable with family; On the other hand, because face of weld is rough state, so the Impact direction on face of weld can be made comparatively to disperse, so after having welded, welding stability of the present utility model is promoted (namely after force dispersion, each component relatively can be less, and the stressed meeting simultaneously on opposite direction is cancelled out each other) significantly, therefore the utility model has stable sealing, and welded structure intensity has the raising of conspicuousness.

Accompanying drawing explanation

Fig. 2 is the front view of the utility model Welded fitting embodiment;

Fig. 3 is the side view of the utility model Welded fitting embodiment.

Reference character: 1, weld body; 2, concave curvature; 3, connecting tube.

Embodiment

Referring to figs. 1 through Fig. 3, the utility model Welded fitting embodiment is described further.

A kind of Welded fitting, comprise welding body 1 in a tubular form and connecting tube 3, welding body 1 and connecting tube 3 one and coaxially arrange, the diameter of welded pipe is greater than the diameter (namely welding body 1 to be positioned on the outer side wall of connecting tube 3) of connecting tube 3, the end wall of welding body 1 is set to face of weld, face of weld is provided with multiple concave curvature 2, namely the intermediate portion of this concave curvature 2 is arranged to the other end depression of welding body 1, the two ends setting concordant with face of weld of concave curvature 2 simultaneously, thus to increase the bonding area on face of weld.

Further, concave curvature 2 is along the circumferential surface extended (face of weld in the utility model is a ring surface on the projection surface) of welding body 1, this setting can increase the epitaxial growth degree of concave curvature 2, thus increases the area of concave curvature 2, to increase the area of face of weld; Also facilitate production of the present utility model simultaneously, namely cost-saving.

Further, concave curvature 2 is provided with two, in the technical program, two concave curvature 2 are set for preferred technological scheme, because when concave curvature 2 arranges too much, the difficulty of production can be increased, namely improve production cost, and after two concave curvature 2 are set, the male and fomale(M&F) of face of weld can be increased to a certain extent, thus with increase the utility model welded after and join strength between pipeline, ensure stable and sealing between the two.

Further, the symmetrical setting of diameter of concave curvature 2 correspondence welding body 1, this setting can increase the distributing homogeneity of concave curvature 2, thus each component on face of weld can be made can to cancel out each other, to increase stability of the present utility model symmetrically simultaneously.

Further, the area of each described concave curvature 2 is 1/2nd of whole face of weld area, and this is arranged so that, face of weld just has two concave curvature 2 to be formed, thus add the bonding area of face of weld greatly, to increase stability of the present utility model, soundness and sealing.

Further, on connecting tube 3 projection and face of weld, the setting of this connecting tube 3, can play spacing effect to being welded on the pipeline that face of weld (is socketed on connecting tube 3) simultaneously to a certain extent, makes the connection between pipeline and the utility model more stable, firm.

The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
