At present, in the feedwater and fire protection pipeline connecting, extensively adopt mechanical three-way at groove type for building, on pipeline, boring installation threeway is convenient to install take-off line.For being installed, this class threeway all needs with U-shaped structural member or U-bolt, mechanical three-way to be fixed on pipeline, this class accessory size is often all very large, and when the mechanical three-way of large pipeline is especially installed, accessory size is very large, consume a lot of steel, and will take the space of very large conduit shaft.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency of the prior art and shortcoming, disclose a kind of lightweight, easy construction, be convenient to the expansion mechanical three-way installing, take up room little.
For reaching above-mentioned technical purpose, expansion mechanical three-way of the present invention, the inner tube that is through hole by center and the ringfeder, outer ring, the nut that are positioned at inner tube one end form its agent structure, described inner tube and pipeline junction transition zone are the conical surface, described conical surface outside is provided with outer ring, an end face of described outer ring is the cambered surface matching with phase distribution pipes outer round surface, in described outer ring, there is ringfeder, there is big sealing ring described ringfeder outside, in the hole of described ringfeder right-hand member outer ring, there is small sealing ring, described outer ring right-hand member is provided with nut, and described nut is fixed in inner tube by threaded together; The right-hand member of described inner tube is provided with flat side, and inner tube right-hand member outside is provided with pipe thread.
For making technique effect of the present invention reach best, the outer ring internal diameter of expansion mechanical three-way of the present invention is identical with ringfeder outside dimension.
As another kind of preferred version of the present invention, the wherein said conical surface can be provided with minute tapering breach such as four roads.
Owing to having adopted technique scheme, the invention has the beneficial effects as follows: 1) because inner tube and pipeline junction transition zone are the conical surface, its conical surface and the pipeline inner circle of installing match, and can avoid mechanical three-way by spanner switching after being arranged on pipeline, and then avoid mechanical three-way to lose efficacy; 2) described outer ring end face is the cambered surface matching with phase distribution pipes outer round surface, between the two, can fit completely, simultaneously owing to adding ringfeder, in specific operation, can ringfeder be out of shape by fastening nuts, and then be stuck in completely in the hole that pipeline offers, in addition the good sealability of big sealing ring and small sealing ring, make it in use the accidents such as leakage can not occur, it is very convenient to install; 3) simultaneously, the large cylindrical of inner tube and the transition zone of little cylindrical are processed into after the conical surface, also can process at conical surface place minute tapering breach such as four roads, make original conical surface become four segments, can in installation process, prevent from spinning equally; 4) at the little cylindrical the other end, be screw thread, nut be installed, with screw thread near be a flat side in place, the inner tube end beyond flat side is screw thread, when connecting other pipe fitting on pipe thread, flat horizontal is put spanner, prevents switching mechanical three-way when pipe fitting is installed.

Embodiment
In order to make the advantage of object of the present invention and technological scheme clearer, below in conjunction with accompanying drawing and example, the present invention is further elaborated.
With reference to Fig. 1 ~ Fig. 3, expansion mechanical three-way of the present invention, the inner tube that is through hole by center (1) and be positioned at the ringfeder (3) of inner tube one end, outer ring (4) and nut (2) form its agent structure, described inner tube (1) is the conical surface (10) with pipeline (13) joint transition zone, the described conical surface (10) outside is provided with outer ring (4), an end face of described outer ring (4) is the cambered surface matching with phase distribution pipes (13) outer round surface, in described outer ring (4), there is ringfeder (3), there is big sealing ring (5) described ringfeder (3) outside, in the hole of described ringfeder right-hand member outer ring (4), there is small sealing ring (6), described outer ring (4) right-hand member is provided with nut (2), described nut (2) is fixed in inner tube (1) by threaded together (7), the right-hand member of described inner tube (1) is provided with flat side (9), and inner tube (1) right-hand member outside is provided with pipe thread (8), outer ring (4) internal diameter is identical with ringfeder (3) outside dimension.
