Abstract
The utility model discloses a direct welding formula connects, including connecting the body, nut, connecting pipe and welding ends, the one end of connecting pipe stretches into the inside that connects the body to nut through connecting on the body carries out sealing connection, connect the body keep away from the connecting pipe one end be equipped with the welding ends, the inboard of welding ends is equipped with the second inclined plane, the outside that the one end of the joint body was kept away from to the connecting pipe is equipped with first inclined plane. The utility model discloses a through type, it can the reinforce to lead to oil, and loss of pressure is little, and because the welding ends is sunken structure, bonding area is big, and joint strength is high, and the difficult phenomenon that the fracture appears is avoided leading to the fact and is polluted and be extravagant, all is equipped with the inclined plane on the connecting pipe simultaneously, the connection of the pipeline of being convenient for.
Description
Technical field
The utility model relates to oil connection field, specifically a kind of straight-through welded fitting.
Background technology
Existing oil connection, often due to connect the reasons such as insecure, sealing is poor, causes oil pipe easily to come off from oil connection, causes the fuel leakage in oil pipe or splashing, be likely to result in the accidents such as fire.
For the transmission pipeline on the hydraulic tests such as mechanical engineering equipment or lathe, it is used mostly Welding oil pipe joint, but owing to equipment operationally can sustained vibration, and the solder side of welded fitting is less, the most cracking phenomenon, thus cause the liquid in pipeline to expose, cause pollution and waste, time serious, there is accident hazard.
Summary of the invention
The deficiency existed for above-mentioned prior art, the purpose of this utility model is to provide a kind of straight-through welded fitting.
To achieve these goals, the utility model be the technical scheme is that
A kind of straight-through welded fitting, including fittings body, nut, connecting tube and welding ends, the inside of fittings body is stretched in one end of described connecting tube, and be connected and sealed by the nut on fittings body, described fittings body away from connecting tube one end be provided with welding ends, the inner side of welding ends is provided with the second inclined-plane, and described connecting tube is provided with the first inclined-plane away from the outside of one end of fittings body.
Further, one end that described connecting tube is connected with fittings body is provided with sealing ring.
Further, the outside diameter of described welding ends is 18mm, and the degree of depth of welding ends is 7.5mm.
Further, the angle between described first inclined-plane and horizontal plane is 60 degree.
Further, the angle between described second inclined-plane and horizontal plane is 12 degree.
Use after technique scheme, the utility model the most advantageously:
Straight-through welded fitting described in the utility model, use through type, oil filling capacity is strong, and the pressure loss is little, due to the structure that welding ends is concave, bonding area is big, bonding strength is high, is difficult to cracking phenomenon, it is to avoid pollute and waste, it is simultaneously connected with on pipe and is equipped with inclined-plane, it is simple to the connection of pipeline.
Accompanying drawing explanation
With embodiment, the utility model is further illustrated below in conjunction with the accompanying drawings:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is side view of the present utility model.
In reference: 1-fittings body；2-nut；3-connecting tube；4-the first inclined-plane；5-welding ends；6-the second inclined-plane.
Detailed description of the invention
The following stated is only preferred embodiment of the present utility model, the most therefore limits protection domain of the present utility model.
Embodiment, as shown in Figure 1-2, a kind of straight-through welded fitting, including fittings body 1, nut 2, connecting tube 3 and welding ends 5, the inside of fittings body 1 is stretched in one end of connecting tube 3, one end that connecting tube 3 is connected with fittings body 4 is provided with sealing ring, and be connected and sealed by the nut 2 on fittings body 1, fittings body 1 away from connecting tube 3 one end be provided with welding ends 5, the outside diameter of welding ends 5 is 18mm, the degree of depth of welding ends 5 is 7.5mm, the inner side of welding ends 5 is provided with the second inclined-plane 6, angle between second inclined-plane 6 and horizontal plane is 12 degree, connecting tube 3 is provided with the first inclined-plane 4 away from the outside of one end of fittings body 1, angle between first inclined-plane 4 and horizontal plane is 60 degree.
Operation principle: during use, is connected connecting tube 3 with pipeline away from one end of fittings body 1, owing to being provided with the first inclined-plane 4, it is easy to connecting tube 3 and stretches in pipeline, welded pipe is stretched into the inner side of welding ends 5 on fittings body 4, and welds, increase bonding area, so that bonding strength is higher.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize the utility model in other specific forms.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes fallen in the implication of equivalency and scope of claim included in the utility model.Should not be considered as limiting involved claim by any reference in claim.
The above; it is only preferred embodiment of the present utility model; not in order to limit the utility model, every any trickle amendment, equivalent and improvement made above example according to technical spirit of the present utility model, within should be included in the protection domain of technical solutions of the utility model.
