Abstract
The utility model belongs to the technical field of air conditioning refrigeration technologies, and particularly relates to a modified type tee joint pipe fitting. The problems that when a conventional tee joint pipe fitting is mounted, a core is required to be supplemented, the installation is inconvenient, and the like are solved. The modified type tee joint pipe fitting comprises a main pipe body, wherein a branch pipe body which is perpendicular to the main pipe body and communicated with the main pipe body is arranged on the main pipe body. The pipe fitting is characterized in that a connecting pipe communicated with the interior of the main pipe body is arranged at one end of the main pipe body; the connecting pipe is sleeved with an installation nut; first external threads are formed in the other end of the main pipe body; second external threads are formed in the branch pipe body; the external diameter of the main pipe body is smaller than that of the branch pipe body; and the internal diameter of the main pipe body is equal to that of the branch pipe body. Compared with the prior art, the modified type tee joint pipe fitting has the advantages as follows: the structure is simple and reasonable; by the aid of a guiding head, the installation is more convenient; during reducing installation, the core is not required to be supplemented; the application range is wide, and the sealing performance is good; a joint cannot leak easily; and the strength and the cost are high.
Description
Technical field
The utility model belongs to the air-conditioning refrigeration system technical field, especially relates to a kind of improved type tee pipe fitting.
Background technique
Tee pipe fitting is the link between pipe fitting and pipe fitting, is again pipe fitting threeway or tee pipe fitting or tee union, is used in main pipeline and wants the branched pipe place.It is widely used in the fields such as various air-conditionings, chiller plant and machinery.In air-conditioning refrigeration system; tee pipe fitting is generally used for the shunting of coolant; in order to guarantee that the coolant in body does not leak, the joint of threeway and pipe fitting must have sealing preferably, thereby but existing tee pipe fitting often can the phenomenon of leaking closely not occur owing to connecting when mounted.Except outside existing tee pipe fitting also exist: complex structure, cost is high, and inconvenience is installed, intensity is low, Applicable scope is little, need mend the problems such as core when reducing is installed.
The problem existed in order to solve prior art, people have carried out long-term exploration, have proposed solution miscellaneous.For example, Chinese patent literature discloses a kind of right-angle tee [application number: 201220391531.4], comprise a straight shape supervisor, middle part described straight shape supervisor is shaped with and is responsible for vertical arm, the straight shape supervisor upper, lower tube outer end diameter of described right-angle tee is identical with supervisor's external diameter size, respectively be shaped with the cylinder step hole in the upper, lower tube end, the diameter of its cylinder step hole is larger than latus rectum in supervisor.
Such scheme has solved the high problem of existing tee pipe fitting cost to a certain extent, but this scheme still exists: complex structure, and sealing is poor, and inconvenience is installed, and intensity is low, and Applicable scope is little, the problem that need mend core when reducing is installed.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of simple and reasonable, easy for installation, and reducing does not need to mend the improved type tee pipe fitting of core while installing.
For achieving the above object, the utility model has adopted following technical proposal: this improved type tee pipe fitting, comprise the main pipe, described main pipe is provided with perpendicular to main pipe and the Zhi Guanti that is connected with the main pipe, it is characterized in that, described main pipe's one end is provided with the connecting tube be connected with main pipe inside, be arranged with mounting nuts on described connecting tube, described main pipe's the other end is provided with the first outside thread, be provided with the second outside thread on Zhi Guanti, described main pipe's external diameter is less than the external diameter of Zhi Guanti, described main pipe's internal diameter equates with the internal diameter of Zhi Guanti.Without mending core, simultaneously easy for installation while adopting said structure to make reducing install.
In above-mentioned improved type tee pipe fitting, described connecting tube end has installing sleeve, and an end to the other end diameter that described installing sleeve is connected with connecting tube becomes large gradually.
In above-mentioned improved type tee pipe fitting, the outer surface of described installing sleeve is provided with gasket seal.
In above-mentioned improved type tee pipe fitting, the 1.2-1.5 of the external diameter that the external diameter of described Zhi Guanti is the main pipe doubly.
In above-mentioned improved type tee pipe fitting, described main pipe's end is provided with the first tapered guide head, and the end of described Zhi Guanti is provided with the second tapered guide head.
Compared with prior art, the advantage of this improved type tee pipe fitting is: simple and reasonable, guide head makes while installing convenient, without mending core, applied widely when reducing is installed, good airproof performance, and joint is difficult for leaking, and intensity is high, and cost is high.
The accompanying drawing explanation
The structural representation that Fig. 1 provides for the utility model.
In figure, main pipe 1, the first outside thread 11, the first guide head 12, Zhi Guanti 2, the second outside thread 21, the second guide head 22, connecting tube 3, installing sleeve 31, mounting nuts 4, gasket seal 5.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1, this improved type tee pipe fitting, comprise main pipe 1, main pipe 1 is provided with perpendicular to main pipe 1 and the Zhi Guanti 2 that is connected with main pipe 1, main pipe's 1 one ends are provided with the connecting tube 3 be connected with main pipe 1 inside, be arranged with mounting nuts 4 on connecting tube 3, main pipe's 1 the other end is provided with the first outside thread 11, be provided with the second outside thread 21 on Zhi Guanti 2, main pipe 1 external diameter is less than the external diameter of Zhi Guanti 2, main pipe 1 internal diameter equates with the internal diameter of Zhi Guanti 2, without mending core, simultaneously easy for installation while adopting said structure to make reducing install.
As a kind of technological scheme of comparatively optimizing, connecting tube 3 ends in the present embodiment have installing sleeve 31, and an end to the other end diameter that installing sleeve 31 is connected with connecting tube 3 becomes large gradually.The outer surface of installing sleeve 31 is provided with gasket seal 5.The 1.2-1.5 of the external diameter that the external diameter of Zhi Guanti 2 is main pipe 1 doubly.Main pipe 1 end is provided with the first tapered guide head 12, and the end of Zhi Guanti 2 is provided with the second tapered guide head 22.
