Description

A kind of elbow facilitating connection

Technical field

The utility model relates to pipe bending connector, in particular to a kind of elbow for facilitating connection.

Background technique

In heavy construction, the application of material transportation pipeline is more and more extensively that elbow is important in material transportation pipeline One of component, its quality and camber determine the quality of the quality of pipeline entirety.

Notification number is that the Chinese patent of CN201250983Y discloses a kind of socket joint elbow, by socket, bellmouth, bending section Point, the composition such as socket joint slot, have socket joint slot on socket, socket, bellmouth are located at the both ends of bending part.

Elbow pipeline connected to it at present, the connection type of elbow is usually and welds, but actually using at present Cheng Zhong is easy to appear residual dead angle in the seam crossing of elbow, leads to being gathered in seam crossing a part for solder, need work people Member re-starts repair welding to the position of not solder, and polishes again processing to the position of aggregation solder, it has not been convenient to connect.

Utility model content

The purpose of the utility model is to provide a kind of elbows for facilitating connection, the advantage is that and elbow is facilitated to connect with pipeline It is fixed.

The above-mentioned technical purpose of the utility model has the technical scheme that

A kind of elbow facilitating connection, including tube body, one end of the tube body are provided with first interface, the tube body it is another One end is provided with second interface, and internal screw thread is provided on the inner wall of the first interface, and the inner wall inclination of the first interface is set It sets, external screw thread is provided on the outer wall of the second interface, the outer wall of the second interface is also inclined to set, and described second connects The outer diameter of mouth gradually becomes smaller axially outwards along it.

By using above-mentioned technical proposal, when being connected and fixed, pipeline can be with the with externally threaded connector One interface thread is cooperatively connected, and since the inner wall of first interface is obliquely installed, connector is facilitated to be inserted into first interface；The Two interfaces are inserted into the threaded hole of pipeline, have second interface to be inclined to set with externally threaded outer wall, are also facilitated and are inserted Enter and be threadedly coupled, advantageously reduce the operation difficulty of staff, elbow and pipeline is facilitated to be connected and fixed.

Further, the internal diameter of the first interface gradually becomes smaller axially inward along it.

By using above-mentioned technical proposal, i.e. dimension of inner screw thread gradually becomes smaller, and inclined internal screw thread can play certain lead To effect, the connector of extraneous pipeline is facilitated to be inserted into first interface.

Further, the inlet of the first interface is provided with groove, the smooth setting in the surface of the groove.

By using above-mentioned technical proposal, when the connector of extraneous pipeline is initially inserted into first interface, if occurring Deviation, connector and the groove contact of pipeline, the connector edge of groove conduit, which is correctly oriented, to be slid into first interface.

Further, the altitude range of the groove is 0.3 mm to 1.2mm.

By using above-mentioned technical proposal, suitable groove depth is selected according to the pore size of elbow, is conducive to groove Play preferably guidance effect.

Further, the tilt angle of the groove is greater than the tilt angle of first interface.

By using above-mentioned technical proposal, the bayonet of groove is more wide, makes the connector of pipeline is more convenient to be inserted into In first interface.

Further, the first interface is identical with the inclined degree of second interface, the internal diameter of the first interface and Two interface outer diameters are identical.

By using above-mentioned technical proposal, due to needing elbow mutual with elbow sometimes in actual use process Connection, second interface is inserted into first interface at this time and the two is threadedly engaged connection.

Further, the axial angle of the axial direction and second interface of the first interface is 90 °.

By using above-mentioned technical proposal, two different root canal roads are linked together, and are vertically arranged between pipeline.

Further, the knee of the tube body is provided with fillet, and ribs triangular in shape is provided on the fillet.

By using above-mentioned technical proposal, due to the seamed edge that fillet is not sharp, uniform stressed, there is stress concentration in reduction The case where, while ribs further increases the structural strength at fillet, at reduction fillet a possibility that depressed deformation.

In conclusion the utility model has the following beneficial effects:

1. passing through the setting of second interface and first interface, elbow and pipeline is facilitated to be connected and fixed；

2. play guiding function to pipeline by the setting of groove, make Petrochemical Pipe Joints it is more convenient be inserted into In one interface；

3. passing through the setting of ribs and fillet, there is the case where stress concentration in reduction, reduces fillet vertical line depressed deformation A possibility that.
