The purpose of using a uniform gas tee is to ensure uniform gas distribution during connection, adjust flow pressure, improve efficiency and energy saving, and enhance reliability and stability.
[0003] In the existing technology, some heating furnace gas uniformity tees are usually used to connect the heating furnace and the gas delivery pipeline. Most of them are connected through two assembly plates, and then the bolts and nuts are tightened with tools, and then the sealing ring is used to complete the connection of the pipeline and play a sealing role. However, during long-term use, due to the influence of vibration and temperature changes, the seal will not be tight, and the gas will leak from the connection part, affecting the normal operation and work efficiency of the heating furnace. Therefore, in response to the above shortcomings, a heating furnace gas uniformity tee is proposed. Utility Model Content

[0013] The utility model has the following beneficial effects:
[0014] 1. In this utility model, by connecting the pipe to the tee, the dynamic ring and the static ring are brought into contact.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] Reference Figures 1 to 3 The utility model provides an embodiment of a heating furnace gas uniforming tee, including a tee 1, the outside of the tee 1 is fixedly connected to a plurality of connecting pipes 2, which play the role of connecting and transmitting gas, and the outer sides of the multiple connecting pipes 2 are fixedly connected to the mounting plates 3 on the far sides, and the mounting plates 3 provide an installation basis for subsequent connection and sealing structures, and the inner sides of the multiple mounting plates 3 are fixedly connected to a plurality of fixing blocks 4 on the adjacent sides, and the internal sliding connection of the fixing blocks 4 is connected to a sliding rod 5 in a sliding manner, and the fixing blocks 4 provide a stable support for the sliding of the sliding rod 5, and the outer sleeve of the sliding rod 5 is provided with a spring 6 for providing spring force, which will generate rebound force after compression, and the adjacent sides of the multiple sliding rods 5 are fixedly connected to three slip rings 7 for connecting subsequent components;
[0024] The outer sliding connection of the slip ring 7 is inside one side of the mounting plate 3, one end of the spring 6 is fixedly connected to one side of the slip ring 7, and the other end of the spring 6 is fixedly connected to one side of the fixed block 4. This fixed connection is for a stable connection. One side of the slip ring 7 is fixedly connected with a connecting ring 8 for connecting. One side of the connecting ring 8 is fixedly connected with a dynamic ring 9. The adjacent sides of the multiple sliding rods 5 are rotatably connected with an adjustment component for force adjustment. The adjustment component includes a bolt 10, and the far sides of the multiple bolts 10 are respectively rotatably connected to the adjacent sides of the multiple sliding rods 5. The external thread of the bolt 10 is connected with a nut 11. By screwing the nut 11, it can be moved outside the bolt 10 to change the compression degree of the spring 6, thereby adjusting the sealing force. One side of the nut 11 is in contact with one side of the fixed block 4, and the far sides of the multiple mounting plates 3 are provided with an annular hole 12. The outer sliding connection of the connecting ring 8 is inside the annular hole 12 to ensure the stability of the movement.
[0025] Reference Figures 2 to 4 , the far sides of multiple mounting plates 3 are fixedly connected with a connecting assembly for tightening, and the connecting assembly includes a rotating disk 13 for additional support. The upper and lower sides of the rotating disk 13 are fixedly connected with threaded blocks 14, and the external threads of the threaded block 14 are connected to the inside of one side of the mounting plate 3. The outside of the rotating disk 13 is fixedly connected with a rotating block 15, and the upper and lower sides of the rotating disk 13 are respectively fixedly connected to the adjacent sides of the two static rings 16. The inside of the rotating disk 13 is fixedly connected with a filter plate 17, which can effectively filter impurities and particulate matter in the gas. The upper and lower sides of the connecting assembly are fixedly connected with static rings 16, and the outside of the dynamic ring 9 is in contact with the outside of the static ring 16 to jointly achieve a sealing effect.
[0026] Working principle: First, when installing and connecting the gas uniforming tee of the heating furnace, move the pipe close to the tee 1. As the pipe approaches, the static ring 16 on the mounting plate 3 gradually contacts the dynamic ring 9. During the contact process, the dynamic ring 9 is squeezed, driving the sliding rod 5 to slide inside the fixed block 4. The sliding of the sliding rod 5 causes the slip ring 7 to slide inside one side of the mounting plate 3, while compressing the spring 6. After being compressed, the spring 6 generates a rebound force, which acts on the slip ring 7 and the dynamic ring 9, so that the dynamic ring 9 is in close contact with the static ring 16, ensuring good sealing under various working conditions, effectively preventing gas leakage, and improving the reliability of the seal.
[0027] Next, adjust the spring force of spring 6 by turning nut 11, depending on the gas delivery pressure. As nut 11 is turned, it moves outside bolt 10, changing the degree of compression of spring 6 and thus adjusting the sealing force. Whether operating under low or high pressure conditions, the appropriate spring force of spring 6 can be found to ensure a good seal.
[0028] Then, in order to further strengthen the connection between the tee pipe 1 and the pipeline, the rotating block 15 is rotated. The rotating block 15 drives the rotating disk 13 to rotate, and the threaded blocks 14 on the upper and lower sides of the rotating disk 13 are connected to the internal thread on one side of the mounting plate 3 to tighten the tee pipe 1 and the pipeline. The rotation of the rotating disk 13 provides a greater connection force, ensuring that the connection between the tee pipe 1 and the pipeline is more secure and reliable. At the same time, when the gas passes through the tee pipe 1, the filter plate 17 inside the rotating disk 13 plays a role. When the gas passes through the filter plate 17, the filter plate 17 can effectively filter impurities and particulate matter in the gas, prevent them from entering the heating furnace, protect the components inside the heating furnace, and improve the working efficiency and stability of the heating furnace.
[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
