[0008] By adopting the above technical solution, the beneficial effects of the utility model are:

[0009] The straight pipe body is divided into two sections and threadedly connected. The distance between the two sections can be adjusted by screwing to achieve the purpose of adjusting the length of the straight pipe body to meet usage requirements.

[0010] Furthermore, the second straight tube includes an inner tube and an outer tube which are spaced apart inside and outside and have the same center line, and the inner wall of the outer tube is provided with an internal thread; the outer wall of the first straight tube is provided with an external thread, and the external thread is screwed and meshed with the internal thread.

[0011] Furthermore, the first straight tube includes a Y-valve tail end body and a Y-valve tail end head connected as one body, and the side tube is fixed to the end of the Y-valve tail end body close to the Y-valve tail end head; the external thread is provided on the outer wall of the Y-valve tail end body.

[0012] Furthermore, a sealing ring is installed between the inner wall of the first straight tube and the outer wall of the inner tube.

[0013] The beneficial effect of adopting the above further technical solution is to improve the sealing performance.

[0014] Furthermore, the outer diameter of the inner tube is smaller than the outer diameter of the first straight tube, and the inner diameter of the inner tube is smaller than the inner diameter of the first straight tube; the sealing ring is installed in a sealing groove opened on the outer wall of the inner tube.

[0015] The beneficial effect of adopting the above-mentioned further technical solution is that the inner tube forms a certain wall thickness, which provides conditions for opening a sealing groove thereon, improves the sealing performance, avoids the influence on the sealing ring when adjusting the length, and increases the structural stability.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-4 As shown, the embodiment of the utility model discloses an adjustable Y-valve, including a straight pipe body 1 and a side pipe 2 connected as one body, the straight pipe body 1 includes a first straight pipe 11 and a second straight pipe 12, the side pipe 2 is fixed on the first straight pipe 11, and the first straight pipe 11 is threadedly connected with the second straight pipe 12. The utility model divides the straight pipe body 1 into two sections, and adopts threaded connection, and the distance between the two sections can be adjusted by screwing, so as to achieve the purpose of adjusting the length of the straight pipe body 1 and meet the use requirements.

[0023] Specifically, the second straight tube 12 includes an inner tube 121 and an outer tube 122 which are spaced apart and have the same center line. The inner wall of the outer tube 122 is provided with an internal thread. The outer wall of the first straight tube 11 is provided with an external thread which is screwed and meshed with the internal thread.

[0024] Specifically, the first straight tube 11 includes a Y-valve tail end body 111 and a Y-valve tail end head 112 connected as one body, and the side tube 2 is fixed to the end of the Y-valve tail end body 111 close to the Y-valve tail end head 112; an external thread is provided on the outer wall of the Y-valve tail end body 111.
