Description

Technical Field

[0001] This utility model relates to the field of tee pipe technology, and in particular to a connection and sealing structure for a tee pipe fitting. Background Technology

[0002] Tees are commonly used where pipelines branch off, connecting pipes with different directions, making them convenient and simple to use. To facilitate disassembly and reassembly of the tee, a fitting is usually installed at the end of the tee, which securely and seals the connection to the pipeline.

[0003] Typically, the inner or outer wall of the end of a tee pipe is threaded, and the connecting fittings that mate with it are also threaded. Therefore, the tee pipe can be connected to the pipeline by threaded connection of the connecting fittings. During the connection process, white tape needs to be wrapped around the surface of the connecting fittings to ensure the sealing of the connection between the connecting fittings and the tee pipe.

[0004] While this connection allows for connection and disassembly, the sealing performance deteriorates with use, often necessitating the replacement of sealing tape. Furthermore, the aforementioned connection method requires careful consideration of screwing adjustments to position the tee pipe correctly, which is quite inconvenient. Therefore, it is essential to improve upon the existing structural design flaws. Summary of the Invention

[0005] The purpose of this utility model is to solve the problems mentioned in the background art and to provide a connection and sealing structure for a tee fitting.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A connection sealing structure for a tee fitting includes a tee body and a connecting pipe head. A connection sealing assembly is provided at the ends where the tee body and the connecting pipe head connect. The connection sealing assembly includes a fixing ring and a sealing ring. The fixing ring presses the sealing ring into the port of the tee body or the connecting pipe head. When the fixing ring is installed on the tee body or the connecting pipe head, the end face of the fixing ring is inside the port of the tee body or the connecting pipe head. The end of the sealing ring is bent and fitted against the port of the fixing ring. When the fixing ring is installed on the tee body or the connecting pipe head, the end plane of the sealing ring is higher than the port plane of the tee body or the connecting pipe head.

[0007] In the connection and sealing structure of the above-mentioned tee fitting, a fixing groove and a sealing groove are respectively provided at the port of the tee body or the connecting pipe head. The fixing pressure ring forms a fixed connection through the fixing groove, and the sealing ring is positioned and fixedly installed through the fixing pressure ring and the sealing ring.

[0008] In the connection and sealing structure of the above-mentioned tee fitting, the sealing ring is provided with an installation groove, and the fixed pressure ring is provided with a connecting boss. The sealing ring is connected to the fixed pressure ring through the connecting boss.

[0009] In the connection and sealing structure of the above-mentioned tee fitting, the sealing ring includes a body, a pressing root, and a sealing end, and the connecting boss of the fixing ring presses and fixes the pressing root.

[0010] In the connection and sealing structure of the above-mentioned tee fitting, the tee body and the port of the connecting pipe head are respectively provided with a screw-on buckle and a screw-on boss, and a mating screw-on opening is formed between the screw-on buckle and the screw-on boss for the screw-on buckle to pass through.

[0011] In the connection and sealing structure of the aforementioned tee fitting, the sealing ring is an integral structure.

[0012] In the connection and sealing structure of the aforementioned tee fitting, the fixed pressure ring and the fixed groove are fixedly connected by adhesive bonding, heat fusion, or interference fit.

[0013] In the connection and sealing structure of the aforementioned tee fitting, the sealing ring is installed on the fixed pressure ring by ultrasonic connection.

[0014] The advantages of this utility model: This utility model not only facilitates easy disassembly and connection, but also features a designed sealing connection structure that can ensure a long-term and sufficient sealing connection at the pipe opening. The sealing structure can be assembled before pipe connection, eliminating the need for the cumbersome traditional sealing installation process. The connection design between the tee pipe body and the connecting pipe head not only facilitates connection and installation without considering placement limitations, but also, combined with the sealing structure design, makes the connection more robust and airtight.

[0015] The sealing ring is installed on the fixed pressure ring using ultrasonic connection to achieve a high-strength, high-sealing permanent connection that will not fall off during disassembly, ensuring the sealing of the connection. Attached Figure Description

[0023] Please see Figures 1 to 6 The present invention provides a connection sealing structure for a tee fitting, comprising a tee body 1 and a connecting pipe head 2. A connection sealing assembly is provided at the ends where the tee body 1 and the connecting pipe head 2 are connected. The connection sealing assembly includes a fixing ring 3 and a sealing ring 4. The fixing ring 3 presses the sealing ring into the port of the tee body 1 or the connecting pipe head 2. When the fixing ring 3 is installed on the tee body 1 or the connecting pipe head 2, the end face of the fixing ring 3 is inside the port of the tee body 1 or the connecting pipe head 2. The end of the sealing ring 4 is bent and fitted to the port of the fixing ring 3. When the fixing ring 3 is installed on the tee body 1 or the connecting pipe head 2, the end plane of the sealing ring 4 is higher than the port plane of the tee body 1 or the connecting pipe head 2.

[0024] Furthermore, a fixing groove 5 and a sealing groove 6 are respectively provided at the port of the three-way pipe body 1 or the connecting pipe head 2. The fixing pressure ring 3 forms a fixed connection through the fixing groove 5, and the sealing ring 4 is positioned and fixedly installed through the fixing pressure ring 3 and the sealing ring 4.

[0025] Furthermore, the sealing ring 4 is provided with an installation groove 7, and the fixing ring 3 is provided with a connecting boss 8. The sealing ring 4 is connected to the fixing ring 3 through the connecting boss 8.

[0026] Furthermore, the sealing ring 4 includes a main body 9, a pressing root 10, and a sealing end 11, and the connecting boss 8 of the fixing ring 3 presses and fixes the pressing root 10.

[0027] Furthermore, the three-way pipe body 1 and the connecting pipe head 2 are respectively provided with a screw-on buckle 12 and a screw-on boss 13, and a mating screw-on opening 14 is formed between the screw-on buckle 12 and the screw-on boss 13 for the screw-on buckle 12 to pass through.

[0028] Furthermore, the sealing ring 4 is installed on the fixing pressure ring 3 by ultrasonic connection. Preferably, the sealing ring 4 is an integral structure.

[0029] Furthermore, the fixing ring 3 and the fixing groove 5 are fixedly connected by adhesive bonding, heat fusion, or interference fit.

[0030] Before the T-fitting is installed, the fixing ring 3 and sealing ring 4 are usually already assembled at the port of the T-fitting body 1 or the connecting head 2. During the connection, the screw clips 12 on the T-fitting body 1 and the connecting head 2 pass through the mating screw openings 14 on each other, and then rotate, so that the screw clips 12 on the T-fitting body 1 and the connecting head 2 form a snap with the screw protrusions 13 on each other, thereby completing the fixed connection.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
