Abstract
The utility model discloses a reducing tee joint which comprises a straight joint and a side joint, wherein the straight joint is provided with a first interface and a second interface which are connected with pipelines; the side joint is provided with a third interface connected with the pipelines; the diameter of the first interface is smaller than that of the second interface. The utility model solves the problems of time waste, labor waste and high installation cost because the reducing installation is completed by the mode of increasing complement cores in the process of the reducing installation of the pipelines. Because in the reducing installation of the pipelines, the utility model matched with the connected pipelines is selected for direct installation without regulating the pipe diameter by the complement cores, the utility model has the advantages of time saving, labor saving and low installation cost, and is used for the reducing installation of various pipelines.
Description
Technical field
The utility model relates to a kind of link that is used for piping erection, relates in particular to a kind of reducing tee.
Background technique
At present, three of use were connected with equal tee and reducing tee during the hot-water heating pipe fitting was installed, and equal tee is used for isodiametric pipeline and connects; The straight-through direction that reducing tee is meant threeway is reducing not, and the diameter of the connection mouth of the logical part of side diminishes.But in installing and using process, can run into the different pipeline of various diameters and connect, often need to finish the reducing installation by increasing modes such as mending core, waste time and energy, installation cost is also high.
Summary of the invention
Goal of the invention of the present utility model is: provides a kind of in the reducing installation process of pipeline, need not just can finish the reducing installation by increasing the benefit core, and time saving and energy saving, the reducing tee that installation cost is low.
For achieving the above object, the technical solution of the utility model is: a kind of reducing tee comprises: straight-through and side is led to, and leads directly to have first interface and second interface that can be connected with pipeline, side is logical to have the 3rd interface that can be connected with pipeline, and the diameter of first interface is less than the diameter of second interface.
Owing to adopted technique scheme, in the reducing installation process of pipeline, choose the reducing tee that is complementary with the pipeline that is connected, directly install, need not to mend core and carry out the caliber adjusting, time saving and energy saving, installation cost is low.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model reducing tee first embodiment's a structure sectional view;
Fig. 2 is the utility model reducing tee second embodiment's a structure sectional view;
Fig. 3 is the utility model reducing tee the 3rd embodiment's a structure sectional view;
Fig. 4 is the utility model reducing tee the 4th embodiment's a structure sectional view.
Embodiment
First embodiment: as shown in Figure 1, a kind of reducing tee, comprise: straight-through 1 and side logical 2, straight-through 1 has the first interface 1a and the second interface 1b that can be connected with pipeline, side logical 2 has the 3rd interface 2c that can be connected with pipeline, the diameter of the first interface 1a is less than the diameter of the second interface 1b, and the diameter of the 3rd interface 2c equals the diameter of the first interface 1a.
Second embodiment: as shown in Figure 2, the structure and first embodiment are basic identical, and its difference is: the diameter of the 3rd interface 2c is less than the diameter of the first interface 1a.
The 3rd embodiment: as shown in Figure 3, the structure and first embodiment are basic identical, and its difference is: the diameter of the 3rd interface 2c greater than the diameter of the first interface 1a less than the diameter of the second interface 1b.
The 4th embodiment: as shown in Figure 4, the structure and first embodiment are basic identical, and its difference is: the diameter of the first interface 1a equals the diameter of the second interface 1b, and the diameter of the 3rd interface 2c is greater than the diameter of the first interface 1a or the second interface 1b.
Among first, second, third and fourth embodiment straight-through 1 can be set to side logical 2: the identical and external diameter difference of pipe thickness, also can be arranged to the pipe thickness difference and external diameter is identical.
In addition, each connection mouth can be provided with screw thread and be connected with pipeline thread, also can not establish the direct and pipe bonding of screw thread.
In the reducing installation process of pipeline, choose the reducing tee that is complementary with the pipeline that is connected, directly install, need not to mend core and carry out the caliber adjusting, time saving and energy saving, installation cost is low.
