Abstract
The utility model discloses a kind of T-shaped metal three-way pipe, comprise the first body, the second body and the 3rd body, one end of described first body and the second body is wholely set, and become T-shaped setting with the 3rd body, described 3rd body is mutually extruded by the first body and the second body and forms, and the end face of one end that described first body, the second body are connected with external pipe with the 3rd body all offers annular groove.T-shaped metal three-way pipe of the present utility model, formation the 3rd body is mutually extruded by utilizing the first body and the second body, just do not need extra welding the 3rd body, and the setting of annular groove, external pipe just can be embedded in groove, so just effectively can increase the sealing of three-way pipe.
Description
Technical field
The utility model relates to a kind of pipeline, relates to a kind of T-shaped metal three-way pipe in particular.
Background technique
It is very general that metallic conduit uses in the process of liquid, gas conveying; just effectively liquid or gas can be transported to the position of specifying by the connection between pipeline; the situation needing threeway often can be run into, thus three-way pipe very general in the application of reality in the process of conveying.
More common three-way pipe is T-shaped metal three-way pipe at present, this pipeline comprises the first body, second body and the 3rd body, one end of three bodys is interconnected and is communicated with, and in 90 degree of settings, so just effectively can reach the effect of a threeway, wherein the first body here and the second body are wholely set, form a longer body, the tube wall of this body sets out a through hole, then is got on by the welding of thermofussion welding technology in one end of the 3rd body, but the three-way pipe of this structure, because the 3rd body is got on by thermofussion welding technology extra soldered, so just there will be rosin joint to cause the problem that three-way pipe sealing is not strong in the process used, this first body simultaneously, second body and the 3rd body are with the Placement of external pipe and weld, and the first body, the connecting end surface of the second body and the 3rd body and external pipe is plane, thus be easy to after having welded occur that the sealing that rosin joint causes three-way pipe to be connected with external pipe goes wrong.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is the T-shaped metal three-way pipe providing a kind of sealing strong.
For achieving the above object, the utility model provides following technological scheme: a kind of T-shaped metal three-way pipe, comprise the first body, the second body and the 3rd body, one end of described first body and the second body is wholely set, and become T-shaped setting with the 3rd body, described 3rd body is mutually extruded by the first body and the second body and forms, and the end face of one end that described first body, the second body are connected with external pipe with the 3rd body all offers annular groove.
By adopting technique scheme, by by the 3rd body be the first body and the second body extruding form, so the 3rd body, the first body and the second body are wholely set, the 3rd body would not be there is like this and the problem of rosin joint between the first body and the second body, effectively add the sealing of three-way pipe, simultaneously by the setting of annular groove, when connection external pipe, just external pipe can be embedded in annular groove and weld again, so just can effectively avoid causing with external pipe rosin joint the problem that sealing is not strong.
The utility model is set to further: two cell walls of described annular groove are evenly distributed with several projections.
By adopting technique scheme, by the setting of projection, when three-way pipe and external pipe carry out sweat soldering, projection will melt, change into molten metal, this molten metal will be paved with the space in annular groove, welding between three-way pipe with external pipe so just can be made to there will not be the problem of rosin joint, add the sealing be connected between three-way pipeline with external pipe greatly.
The utility model is set to further: described projection shape is hemispherical.
By adopting technique scheme, projection being arranged to hemispherical, seeming more round and smooth when external pipe is inserted in annular groove, and hemispheric setting also makes projection more easily melt to fill up space.
In the utility model embodiment, the first body, the second body and the 3rd body are made by copper product.
Accompanying drawing explanation
Fig. 1 is the sectional view of T-shaped metal three-way pipe of the present utility model;
Fig. 2 is the enlarged view in A portion in Fig. 1.
In figure: 1, the first body; 2, the second body; 3, the 3rd body; 4, annular groove; 41, projection.
Embodiment
Shown in 2, the T-shaped metal three-way pipe of one of the present embodiment, comprise the first body 1, second body 2 and the 3rd body 3, one end of described first body 1 and the second body 2 is wholely set, and with the T-shaped setting of the 3rd body 3 one-tenth, described 3rd body 3 is mutually extruded by the first body 1 and the second body 2 and forms, and the end face of one end that described first body 1, second body 2 is connected with external pipe with the 3rd body 3 all offers annular groove 4.
By adopting technique scheme, when making three-way pipe, only need to get the connecting body of a long tube as the first body 1 and the second body 2, then on the tube wall of long tube, a cylindric protuberance is squeezed out by extrusion die, then bump is carried out opening, this completes the making to three-way pipe, the 3rd body 3 and first can be found out, second body 2 is wholely set, carry out having welded with regard to not needing like this, the 3rd body 3 and first would not be there is like this, the problem of rosin joint between second body 2, considerably increase the sealing of three-way pipe, when connecting tee pipe and external pipe, the tube wall of one end of external pipe is only needed to be embedded in annular groove 4, and then adopt thermofussion welding technology to weld it, welding the tube wall completed due to external pipe be embedded in annular groove 4 completely, so would not occur that rosin joint causes occurring gap between external pipe and three-way pipe, make the problem that sealing declines.
Above the connection procedure of three-way pipe and external pipe and principle are described in further detail.
With reference to shown in Fig. 2, when needs connect external pipe and three-way pipe time, first tube wall external pipe being connected one end with three-way pipe is embedded in annular groove 4, then its attachment portion is heated, in the process of heating, the projection 41 be distributed in annular groove 4 will slowly melt, be melted into molten metal to flow in annular groove 4, when the gap that molten metal fills up in annular groove 4 completely, just no longer heat, molten metal will slowly solidify, so just can effectively the tube wall of external pipe and the tube wall of three-way pipe be welded firmly, and be similar to and be wholely set, so just can avoid the problem of rosin joint, add the sealing be connected between three-way pipe with external pipe greatly.
In sum, by extruding the first body 1 and the second body 2 forms the 3rd body 3, three of the three-way pipe of the present embodiment bodys are just made to be wholely set, effectively add its sealing, by the setting of annular groove 4, the tube wall of external pipe just can be made when the three-way pipe of the present embodiment is connected with external pipe to be embedded in annular groove 4, to be just not easy the problem occurring rosin joint, to add the sealing that three-way pipe is connected with external pipe.
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.
