Abstract
The utility model relates to a T-branch pipe and aims to provide a reliable connection type T-branch pipe which is convenient to machine. The reliable connection type T-branch pipe comprises a T-branch pipe body formed by three sections of pipe bodies, wherein the three sections of pipe bodies are communicated, and external threads are arranged at the end of each pipe body. The reliable connection type T-branch pipe is characterized in that an annular groove is formed in the inner end of the external threads of each pipe body, and the outer diameter of the external threads outside the annular groove is smaller than or equal to the outer diameter of the pipe body inside the annular groove. Due to the arrangement of the annular grooves, the screwing length of a nut can be increased, threaded connection is made to be tighter, and machining of the external threads is facilitated. Furthermore, a sealing ring can be installed in advance in each annular groove before the connection with the nut, and therefore the sealing performance of the threaded connection is improved. The reliable connection type T-branch pipe solves the technical problems existing in the field for a long time through structural improvement.
Description
Technical field
The utility model relates to pipe joint or claims pipe fitting, is specifically related to three-way pipe.
Background technique
The pipe joint of three openings is arranged three-way pipe, also can be understood as three bodys and be connected and constitute the three-way pipe body.Three-way pipe is widely used in the pipe network of carrying liquid, gas.Be used for realizing mixed flow or the shunting of material.Three bodys on the three-way pipe can be caliber identical also can be different.
Pipe end on the three-way pipe of prior art arranges outside thread usually so that join with other parts.Usually outside thread to the body portion caliber between the body joint of three-way pipe body less than externally threaded external diameter; The screw-in length of nut is secure in such structure, and the sealing reliability of connection is better.But external thread section normally is welded on the body in such structure; That perhaps earlier the externally threaded position of preprocessing is processed is thicker, and then threading; But the processing of dual mode is all very inconvenient.
Or direct threading on the body of three-way pipe body, easy to process like this, but externally threaded limited length, the screw-in length of nut is difficult to guarantee that it is unreliable to connect sealing.
Summary of the invention
The purpose of this utility model provide a kind of easy to process, connect reliable three-way pipe.
For achieving the above object, the utility model has adopted following technological scheme: a kind of three-way pipe, comprise that three sections bodys are communicated with the three-way pipe body that constitutes, outside thread is set on the pipe end, it is characterized in that: described outside thread the inner arranges circular groove, and the externally threaded external diameter of described ring slot outside is smaller or equal to the external diameter of the body of circular groove inboard.
Preferably, the outside thread of described ring slot outside equates with the external diameter of the body of inboard.
Preferably, the width dimensions of described circular groove is more than or equal to 2mm, and depth dimensions is more than or equal to 1mm.
Preferably, the width of described circular groove equals 2.5mm, and depth dimensions equals 1.5mm.
The beneficial effects of the utility model are: in the said structure, circular groove not only can increase the screw-in length of nut, make be threaded tightr; Also be convenient to externally threaded processing.Especially the utility model is big or identical with the body external diameter than inboard smooth outer wall of the major diameter of external thread setting of this ring slot outside, seal ring or the winding unsintered tape formation of can packing in advance in circular groove like this is protruding, and then the attaching nut, be threaded with regard to many resealing guarantees.
According to above-mentioned purpose, circular groove of the present utility model will reach enough width, the degree of depth, the purpose that is able to install seal ring, and also the body caliber of circular groove inboard also must not be less than externally threaded caliber, to guarantee that axial displacement does not take place seal ring.The utility model has solved related domain technical barrier for a long time by architecture advances.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of three-way pipe as shown in Figure 1 comprises that three sections bodys 1 are communicated with the three-way pipe body that constitutes, and body arranges outside thread 2 on 1 termination, and outside thread 2 the inners arrange circular groove 3, and the external diameter of the outside thread 2 in described circular groove 3 outsides and the body 1 of circular groove 3 inboards equates; Perhaps externally threaded external diameter is smaller.
Add man-hour, process circular groove 3 at body 1 earlier, then at ring slot outside threading 2, the external diameter of the outside thread 2 just external diameter with body 1 is identical, perhaps repeats outside thread processing several times, and the external diameter of outside thread 2 is just little than body 1 so.
As for the size and dimension of circular groove 3, the width of preferred circular groove 3 equals 2.5mm, and depth dimensions equals 1.5mm.Can place seal ring like this, not influence the arrangement structural behaviour of body 1 again.Certainly, if the size of body 1 increases, then the size of circular groove 3 can correspondingly increase.
Claims (4)
1. three-way pipe, comprise that three sections bodys are communicated with the three-way pipe body that constitutes, outside thread is set on the pipe end, it is characterized in that: described outside thread the inner arranges circular groove, and the externally threaded external diameter of described ring slot outside is smaller or equal to the external diameter of the body of circular groove inboard.
2. three-way pipe according to claim 1 is characterized in that: the outside thread of described ring slot outside equates with the external diameter of inboard body.
3. three-way pipe according to claim 2, it is characterized in that: the width dimensions of described circular groove is more than or equal to 2mm, and depth dimensions is more than or equal to 1mm.
4. three-way pipe according to claim 3, it is characterized in that: the width of described circular groove equals 2.5mm, and depth dimensions equals 1.5mm.
