[0028] The utility model provides Figure 1-5 A three-way ball valve for filtering dirt shown includes a pipeline 1 for conveying a medium fluid;

[0029] T-type ball valve 2, movably arranged inside pipeline 1, used for cutting off, distributing and changing the medium;

[0030] The adapter 10 is movably connected to both sides of the pipeline 1 and is used to connect equipment;

[0031] The connecting sleeve 14 is fixedly installed on one side of the pipeline 1. The inner two side surfaces of the connecting sleeve 14 are provided with card grooves 15. The card groove 15 is movably connected with a card block 16. A jacket 17 is fixedly installed on one side of the card block 16. Seals 18 are arranged on the outer sides of the jacket 17. Threaded grooves 19 are arranged on the front two side surfaces of the jacket 17. A handle 20 is fixedly installed on the top of the jacket 17. A filter screen 21 is fixedly arranged inside the jacket 17. The filter screen 21 is used to filter impurities in the fluid medium. Bolts 22 are penetrated on both sides of the front of the jacket 17. The filter screen 21 arranged inside the connecting sleeve 14 at the input end of the pipeline 1 can block impurities and dirt in the fluid, thereby improving the use effect in the three-way ball valve and avoiding contamination of the fluid. The filter screen 21 needs to be cleaned regularly for long-term use. The bolts 22 on one side of the connecting sleeve 14 are loosened and removed, and then the jacket 17 and the filter screen 21 are pulled out of the card groove 15 in the connecting sleeve 14 to release the limit. After that, the filter screen 21 can be cleaned and replaced.

[0032] like Figure 1 and Figure 2 As shown, a transmission block 3 is fixedly connected to the top of the T-type ball valve 2, and limiting grooves 4 are provided on both side surfaces above the transmission block 3. The limiting grooves 4 are internally movably connected to limiting blocks 5, and a handle 6 is fixedly installed on one side of the limiting block 5. A threaded column 7 is fixedly installed on the upper end of the transmission block 3, and a nut 8 is movably connected to one end of the threaded column 7. The limiting block 5 fixedly installed below the handle 6 is inserted into the limiting groove 4 above the transmission block 3, which not only improves the docking installation of the two, but also enhances the stability of the rotation of the handle 6.

[0033] like Figure 1 and Figure 3 As shown, a sealing ring 11 is provided on the outside of one side of the adapter 10, an external thread 12 is provided on the outside of one side of the adapter 10, and a second internal thread 13 is provided on one end of the adapter 10. The adapter 10 is threadedly connected to the pipeline 1, and installation and disassembly become simple and convenient. At the same time, the adapter 10 can be used to produce various specifications according to customer requirements. After such a valve body is produced, there can be options for water outlet external pipes of various specifications, and the production is efficient and flexible.

[0034] like Figure 1 , Figure 4 and Figure 5 As shown, the card slot 15 opened inside the connecting sleeve 14 and the card block 16 fixedly installed under the outer sleeve 17 form a card-engaging connection. The card slot 15 and the card block 16 are used in conjunction with each other. The cooperation between the card slot 15 and the card block 16 improves the docking and stability of the outer sleeve 17 during installation and prevents looseness from occurring.

[0035] like Figure 4 and Figure 5 As shown, the seals 18 are respectively arranged on the front and rear sides of the outer sleeve 17. The seals 18 are arranged in a "U" shape.

The bolts 22 are symmetrically arranged with respect to the central axis of the connecting sleeve 14. The connecting sleeve 14 and the outer sleeve 17 are assembled by using the bolts 22, thereby improving the connectivity and avoiding looseness.

[0037] The working principle of the utility model is as follows: firstly, the external thread 12 at one end of the adapter 10 is aligned with the first internal thread 9 inside the pipe 1 for threaded connection, and then the one end of the adapter 10 is connected to the setting of the medium to be transported, and then the connecting sleeve 14 is connected to the transported medium fluid. When the connection is completed, the medium fluid is transported from the connecting sleeve 14 in front of the pipe 1. When the medium fluid passes through the filter screen 21 inside the connecting sleeve 14 during the transportation process, the impurities and dirt in the fluid are blocked, thereby improving the filtering effect of the overall device. When the medium fluid needs to be transported to the right side of the pipe 1, the handle 6 is turned 45° to the right, and the transported medium fluid enters In the pipe 1 on the right, and when it is necessary to transport the pipe 1 on the left, it is rotated 90° in the opposite direction. At this time, the medium fluid is transported to the pipe 1 on the left. Later, when used for a long time, impurities will remain on the surface of the filter screen 21. In order to avoid blockage, loosen the bolt 22 in front of the connecting sleeve 14, loosen the outer sleeve 17 and the filter screen 21, and then pull the handle 20 above the outer sleeve 17 to pull it out from the slot 15 in the connecting sleeve 14. After pulling it out, the surface of the filter screen 21 can be cleaned and replaced. After cleaning, the filter screen 21 is installed again in the same way as before. In this way, the use process of the three-way ball valve that is easy to filter dirt is completed.
