Description

Technical Field

[0001] The utility model belongs to the technical field of home decoration PPR water supply, in particular to a quick-insert three-way pipe fitting. Background Art

[0002] Most current water systems on the market use taps at the end of the pipe or connect water fixtures directly to the pipes. This fixes the location of water fixtures and prevents them from being moved. Some water points are even not originally planned, making it inconvenient to add them later. For example, a large proportion of people in northern China use wall-mounted boilers for heating, using heat sinks in their rooms to achieve heat exchange. However, these boilers are only used during the heating season and are unused the rest of the time. They not only take up a lot of space but are also unsightly. Therefore, achieving plug-and-play functionality for water fixtures became a pressing issue. Utility Model Content

[0019] In order to better understand the purpose, structure and function of the present invention, a quick-insert three-way pipe fitting of the present invention is further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-4 As shown, a quick-insert three-way pipe fitting of the present invention comprises a three-way pipe fitting body 1, a copper insert 7, a quick-insert valve core 4, a bushing 9, a locking ring 8 and a quick-insert port 6, and each component is a hollow pipe fitting. The three-way pipe fitting body 1 is a three-way structure, including a left valve port 11, a right valve port 12 and an upper valve port 13. A platform sealing surface is provided in the middle of the three-way pipe fitting body 1, which is similar to the stop valve body. The bushing 9 is arranged at the lower part of the upper valve port 13 and is clearance-matched with the three-way pipe fitting body 1. The copper insert 7 is arranged inside the upper valve port 13 to provide the connection strength of the quick-insert port 6; the locking ring 8 is fixed on the inner side of the copper insert 7 to compress the bushing 9; the quick-insert valve core 4 is arranged on the inner wall of the bushing 9 through the elastic member 5 and is sealed with the inner wall of the bushing 9. The bottom of the quick-insert valve core 4 has three special-shaped holes 42 on the side, and the quick-insert port 6 can be threadedly connected to the inner side of the upper end of the copper insert 7. Under normal circumstances, the three special-shaped holes 42 on the bottom side of the quick-insert valve core 4 are placed in the bushing 9 under the action of the elastic force of the elastic member 5, blocking the passage of the upper valve port 13. When the quick-insert port 6 is rotated into the copper insert 7 , the quick-insert valve core 4 is pressed by the quick-insert port 6 , and the special-shaped hole 42 extends out of the bottom of the bushing 9 to form a passage with the right valve port 12 .

[0021] like Figure 2 As shown, the upper inner wall of the copper insert 7 is provided with two raised semicircular shoulders 71, which are used to mate with the quick-connect socket 6 and facilitate insertion and rotational tightening of the quick-connect socket 6. The outer ring of the copper insert 7 is provided with a dovetail groove 73 to enhance the bonding strength with the tee pipe fitting body 1. The interior is provided with threads 72, which are used to mate with the locking ring 8 to tighten and secure the bushing 9. An anti-rotation structure 74 is provided at the bottom of the copper insert 7 to enhance its torsional strength.

[0022] The outer surface of the quick-insert valve core 4 is provided with two sealing ring grooves 41, each containing a sealing ring 1 2 and a sealing ring 2 3, respectively, for sealing against the bushing 9. The three elliptical holes 42 at the bottom of the quick-insert valve core 4 increase the flow cross-section and shorten the valve core insertion stroke, achieving a larger flow cross-section with a shorter insertion stroke. The upper end of the quick-insert valve core 4 has a stepped portion 43, which limits the insertion distance of the quick-insert valve core 4. When inserted to the lowest point, the stepped portion 43 contacts the upper end of the bushing 9.

[0023] There is a clearance fit between the bushing 9 and the tee pipe fitting body 1 , and a sealing ring 10 is provided inside the bushing 9 and the tee pipe fitting body 1 .

[0024] The outer wall of the locking ring 8 has an external thread, which cooperates with the thread 72 of the copper insert 7 and is tightened to fix and compress the bushing 9.

[0025] The elastic member 5 is disposed between the step portion 43 of the quick-insert valve core 4 and the end surface of the bushing 9 .

[0026] The quick-insert port 6 has a notch 61 on the outside and a sealing groove 62 on the bottom. When the quick-insert port 6 is inserted into the copper insert 7, the notch 61 is engaged and fixed with the semicircular shoulder 71 of the copper insert 7. A sealing ring 14 is provided between the sealing groove 62 at the bottom of the quick-insert port 6 and the upper end surface of the quick-insert valve core 4.

[0027] Under normal circumstances, that is, when the quick socket 6 is not inserted, the quick plug valve core 4 and the bushing 9 are sealed, the flow channel is not opened, and water can only enter the left valve port 11 from the right valve port 12 of the three-way pipe fitting. When the quick socket 6 is rotated and inserted, the quick plug valve core 4 moves downward until it contacts the internal end face of the three-way pipe fitting body 1. At this time, water enters the flow channel of the quick plug valve core 4 from the right valve port 12 of the three-way pipe fitting and flows to the upper valve port 13.

[0028] The structure adopted by the utility model can well realize plug-and-play of water use points and can also change the flow direction of the original pipeline.

[0029] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
